Aged garlic is incredibly good for your heart
May 03, 2019 04:18 PM
Natural compounds found in aged garlic can be very beneficial to cardiac health. For example, a 2016 Los Angeles Biomedical Research Institute study on subjects with metabolic syndrome found that aged garlic extract reduced both the accumulation of new plaque within the arteries and the total amount of plaque present as well. Additional research suggests that aged garlic extract can help reduce C-reactive protein and interleukin levels. The polysulfides in garlic also support greater production of the nitric oxide that helps keep your blood vessels supple, reducing another cardiac risk factor.
"The LA BioMed researchers concluded that garlic not only decreased the amount of plaque in the arteries. The extract also stopped new plaque from appearing in the blood vessels. (Related: Aged garlic extract balances your cholesterol levels, study finds.)"

Garlic is an essential ingredient in many kitchens, and also demonstrates an impressive array of health benefits. For example, garlic can encourage higher production of hydrogen sulfide, which helps to keep your blood vessels open and supple, reducing your risk of heart disease. Garlic can help mitigate metabolic syndrome and reduce your risk of several types of cancer, including stomach cancer. By neutralizing enzymes that help break down bone, garlic may also help to ward off osteoarthritis, too.
"Garlic, a member of the onion family, has a centuries-long history of medicinal use on a global scale."

New class of hydrogen sulfide donor molecules
January 16, 2017 10:59 AM
One of the most destructive forces in our bodies is oxidative stress. This causes a breakdown of molecules within the body, which then leads to problems such as heart attacks, cancer, and Alzheimer’s disease. The University of Oregon has just released a study showing that they were able to design organic molecules that can be used to release hydrogen sulfide when oxidative stress triggers it. This compound functions to restore molecular stability within the body. This is just the first step in producing new drugs for treating currently life-threatening conditions.
"Oxidative stress damages cells and is tied especially to heart disease and cancer, as well as Alzheimer's and Parkinson's disease."
Can MSM Help Improve Joint Health?
November 09, 2013 05:58 PM
What is MSM
The initials MSM stands for methyl- sulfonyl – methane commonly known as sulfur. MSM is white sulfur powder which is organic. MSM comes from the ocean and is soluble in water. It is a food commonly found in meats, vegetation, plants and dairy products. In the human body, it is the third largest nutrient. Sulfur is very important in human body; it plays a very critical role in the production of collagen which acts as a building block of skin, joints, nails, hair and other connective tissues.
What are the Benefits of MSM
Physical strain and Osteoarthritis (OA) may lead to swelling and joint pain. The pain caused by OA can be relieved using MSM. From the research done; MSM is believed to have anti-inflammatory effects.
Many people especially the old suffer from joint disease. The OA affected joints suffer from uneven loading, which results to altered lines of weight bearing. Cartilage starts to form to compensate for the uneven load, this leads to formation of deformities and roughening in the surface of the joint. The operation of the joint inflame is affected because the socket and the ball rub unevenly due to the friction of outgrowths of bone and cartilage, called osteophytes.Up to date no cure for OA has been found therefore, the treatment available only eases the symptoms.
How Sulfhur Helps our Body
Sulfur is delivered into our bodies by MSM in a usable way. Sulphur helps in maintaining the connective tissue structure by forming cross linkages. This therefore means that sulphur strengthens the joint tissues.Sulphur is very important for the good health of the joints.Glycosaminoglycans (GAGs) are the crucial building blocks of joint cartilage. GAG molecules are held together by the disulfide bonds. As the name suggests, the disulfide bonds are bonds between 2 atoms of sulphur. Disulfide bridges reduce the conformational flexibility of the GAG chains, hence making the cartilage resilient and firm. Thus the integrity of the cartilage depends on sulphur.
What Is Glutathione Good For?

What is Glutathione?
Glutathione (GSH)is a tripeptide derived from non-proteinaceous amino acids. Contains apeptide bond between the group unusual amino of the cysteine group and the carboxylside chain of glutamate. Glutathione, an antioxidant, helps protect cells from reactive species of oxygen such as free radicals and peroxides. Glutathione is nucleophilic at sulfuracceptors and conjugated electrophilic attack poisonous. Groups thiolare maintained in a reduced state to a concentration of about ~ 5 mM in animal cells. Indeed, glutathione reduces any link disulfideformed with in proteins cytoplasmic cysteines by acting as a donor of electrons.In the process, glutathione is converted to its oxidized form glutathione disulfide (GSSG). Glutathione is found almost exclusively in its reduced form, since the enzyme that turns its oxidized form, glutathione reductase,is constitutively active and inducible to oxidative stress.In fact, the ratio of reduced glutathione to oxidized glutathione in cells is often used scientifically as a measure of cellular toxicity. H2O2+ GSSG + 2 ------- 2GSH H2O.
Advantages of the Glutathione
Before discussing the benefits of L-Glutathione, let's first talk a little about the nutrient. Glutathione is an antioxidant enzyme dominant which is soluble in water.It is absorbed mainly in the liver.It helps fight against free radical damage.The free radical damage is harmful relatives. Glutathione is involved in a variety of other functions in the body.
The function of Glutathione - Benefits of Glutathione
Glutathione works in DNA synthesis and repair, protein and prostaglandin synthesis, and amino acid transport.It helps in the metabolism of carcinogens and toxins.Immune system is improved through the use of Glutathione, and contributes to the prevention of cellular oxidative damage, and activation of enzymes. Glutathione also helps and maintains the functions of other antioxidants.
There is the possibility of a deficiency of glutathione. It usually occurs during aging.For example, it is seen in macular degeneration related to age, diabetes, and lung and gastrointestinal diseases. It may be the cause of pre-eclampsia, Parkinson's, AIDS and other neurodegenerative diseases.
Where to get Glutathione
Some sources of glutathione include fruits such as tomatoes, watermelon, grapefruit, oranges, peaches and cantaloupe.It is found in vegetables such as avocados, potatoes, spinach, okra, acorn squash, and asparagus.It is found in most meats as well. Other sources of vegetables such as broccoli, cabbage, Brussels sprouts, cauliflower, kale, parsley, and not only provide GSH - glutathione peroxidase, but it also stimulates the body to make more BA.Since cooking destroys much of glutathione, you will get more to eat raw or steamed vegetables for the best benefits of Glutathione.
Reduced glutathione is in a supplementation that we personally use a company called source naturals a Natural Product meeting the above requirements.The nutrient content in their signature product - Total Balance.
What Does A Selenium Deficiency cause In The Body?
September 26, 2011 04:56 PM
What is Selenium
Selenium is also known as selenium yeast, selenium sulfide and selenium acid as it has different forms. Its main role in our bodily functions is to work in tandem with Vitamin E. As with vitamin E's main functions, selenium also has been deemed vital in the preservation and elasticity of tissues. It is commonly found from sulfide ores such as pyrite and in some cases can partially replace sulfur. Aside from its uses for health it also is used in industry as chemicals and pigments.
This is defined basically as the lack of Selenium in the body, at depreciated levels that may cause health disorders. For the most part, this mineral can easily be obtained and consumed however unlike other minerals it takes only a little to create a deficiency in the body so it is important to be vigilant about Selenium levels. The most common cause found is impaired intestinal functions as it relates to the absorption of this mineral.
Aging Process Alteration
So much cosmetic products in the market today are geared towards beauty and slowing down the aging process. If you are the kind of person that does not like chemical products on your skin this might be interesting to you. Studies have shown that Selenium is necessary if we want to slow down the process of aging. How does it do it? You may ask. It is by increasing endurance which leads to improved blood and oxygen supply for the muscles of the heart. Another key to how Selenium is essential to a slowed down aging process is that the prostoglandins in the human body which is responsible for high blood pressure protection cannot be formed without selenium. Prostoglandins are substances that aid our body's avoidance of harmful blood clots. With this action, strokes and heart attacks can be prevented. With a deficient amount of selenium in the body these are some of the positive things that you can say good bye to in our body.
Recent research has shown that selenium can aid in preventing cancer. It would seem that patients with low levels of selenium are more prone to certain cancers. Recognition has been given that it does work as an antioxidant. It works in an indirect way. It basically helps other enzymes get rid of the body’s toxic free radicals that may be harmful to our bodies in the long run by causing certain cancers. As something that works in tandem with Vitamin E it should be evident that selenium in itself is able to influence our cells protection against free radicals as Vitamin E does.
Aside from the two major possible health issues from being deficient in selenium mentioned above there is a wide variety of more minor problems that can occur from not having the right levels of this mineral in your body. It can cause joint tissue weakening, hypothyroidism and muscle weakness just to name a few. Over longer periods of time without treatment, it may also cause a steady but gradual decline in mental health.
How Does Glutathione Work in the Body to Detox
May 06, 2011 10:11 AM
Glutathione a Body Detox
Glutathione belongs to the category of antioxidants that the human body can synthesize. It is an organic compound that is quite pervasive in nature as it is found in many multicellular organisms, microscopic or not. Almost all plants and animals are capable of producing glutathione, and, like human beings, they utilize this substance to neutralize free radicals and detoxify heavy metals.
Scavenges Free Radicals
It is common knowledge that free radicals are harmful to our body. It damages tissues, proteins, and even DNA. Free radicals are highly reactive by-products of cellular respiration. Cells utilize oxygen to power their activities, but in the process produce a group of compounds called reactive oxygen species, which change into radicals, harming cell organelles when not disposed of and raising cellular toxicity.
Glutathione is in the employ of every cell, for it is a fundamental part of the antioxidant defense of cells. Throughout the body, it is usually found in its reduced form, which donates reducing equivalents to reactive oxygen species. Glutathione becomes reactive in the process, but easily reacts with other reactive glutathione to form glutathione disulfide. Antioxidant enzymes manufacture glutathione in the presence of glutathione disulfide. This process constitutes the antioxidant mechanism of all cells.
Detoxifies Liver Metabolites
Metabolism is a complex process. Bioactive compounds in the foods we eat produce metabolites and by-products that are not necessarily good for our health. In fact, most of the drugs and medications we take directly harm us. Fortunately, the liver comes to our defense. For example, alcohol is converted into large amounts of acetaldehyde in its first stage of metabolism, creating effects we usually refer to as hangover.
The presence of glutathione enables the liver to easily recuperate from the damages brought on by harmful metabolites. That being said, glutathione in its reduced form does get depleted. One good example is drug overdose. The analgesic paracetamol, or acetaminophen, is known for its toxic by-product that induces liver failure in the absence of glutathione. Drugs are immediately detoxified in the liver with the help of glutathione. Low levels of glutathione may even result in death as is the case with paracetamol overdose.
Expels Foreign Materials
A number of substances in our diet are considered xenobiotics, or foreign materials, by our body. Most of them passes the alimentary canal undigested and enters the colon together with waste materials. However, there are substances that readily undergo absorption in the small intestines, such as trace elements and heavy metals. They pose considerable threats to health when they enter the systemic circulation in large quantities.
Glutathione is one of the compounds that keep xenobiotics in check. It facilitates the excretion of heavy metals and many known toxins. Glutathione conjugation plays a major role in detoxification and quite common at the cellular level. It makes sure that foreign compounds do not undergo reabsorption once it reaches the kidneys, effectively washing them away through the urine.
Protect The Liver with Glutathione And Cysteine
April 23, 2009 01:54 PM
The tripeptide L-glutathione is synthesized in the body from L. glutamic acid, L-cysteine and glycine, a reaction that can occur in any cell of the body although it is essential that it also occurs in the liver. Should glutathione concentrations drop, they can be increased by supplementing with cysteine or any other of the three amino acids that are used in the biosynthesis of this important if substance
The tripeptide exists in two forms: the reduced form (GSH) which contains a sulfhydryl (SH) functional group attached to the cysteinyl part of the molecule, and the oxidized form glutathione disulfide (GSSG). As electrons are lost from the reduced form, two molecules combine to create a dimer formed by a disulfide bridge, the process which can be reversed through reduction of the GSSG. Such electrons are lost during its reaction with free radicals, in which the free radicals are neutralized by the donation of an electron from the oxidized version of glutathione.
The definition of a free radical is a molecule that is lacking one electron from an electronic pair. Its prime purpose is then to steal an electron from the nearest molecule to it. In doing so, it can not only destroy that molecule, but also destroy body cells and lead, not only to premature aging, but also to some potentially fatal conditions.
It is an unusual peptide in that it involves a link between the cysteine amino grouping and the carboxyl functional group of the glutamic acid. It is a powerful antioxidant, acting as an effective free radical scavenger and protecting the body cells from the effects of free radical oxidation. However, it is on its detoxification effect in the liver that we shall focus here prior to discussing some other uses to which the body puts glutathione in its two manifestations.
Much of the detoxification is connected with the thiol group in the molecule. Take mercury for example. The thiol grouping forms a strong Hg-sulfydryl chemical bond within the liver, in the form of a glutathione-mercury chelate. In this form mercury is unable to exert any toxic effect on the body and can be excreted in the normal manner. The same reactive pathway is followed by other heavy metals that can bond to thiol groupings. In this way L-glutathione can protect the liver from the effects of a number of toxic heavy metals such as cadmium and chromium.
This is an important property of the amino acid, particularly in industrial and urban environments where the population is more prone to exposure to heavy metals than their rural counterparts. However, the end result on the glutathione is that it is removed from the body, and, particularly with city dwellers, a supplement may be required to maintain a healthy concentration of this amino acid in the body and in particular in the liver. Therefore, although L-glutathione is not considered an essential amino acid, in that it is biosynthesized within the body, a supplement is sometimes required, particularly by those who live in large cities.
It is important to consider the form in which the glutathione supplement is administered. This is because of the presence of gamma-glutamyltranspeptidase within the digestive system. This enzyme appears to destroy L-glutathione before it can be absorbed in the intestine so normal oral forms of supplementation are likely to be ineffective. Possible forms of effective administration include buccal (between the cheek and teeth) and hypodermically.
An alternative means of supplementation is to take substances such as selenium, methionine, alpha-lipoic acid, vitamin C and glutamine that stimulate the biosynthesis of glutathione. Also, since the substance utilizes the raw materials of L-cysteine, glutamic acid and glycine in its intracellular production, supplementation with these amino acids should also help to produce L-glutathione.
That said, let's return to its antioxidant properties and its effect on the liver that contains the largest stocks of glutathione in the body. It is generally regarded as the most important antioxidant in the body. It protects cellular cytoplasm from oxidation by reducing disulfide groups and maintaining a highly reducing environment within the cytoplasm. It reacts with hydrogen peroxide and other oxidative agents, and is converted to the oxidized form GSSG. It is then reduced back to GSH through the combination of the reducing agent and an enzyme. The reducing agent is nicotinamide adenine dinucleotide phosphate (NADPH), the enzyme being glutathione reductase.
The implications that this strong reducing effect has on the liver are significant. Reduced GSH L-glutathione levels have been found in patients suffering from HIV, hepatitis C and other liver diseases. Supplementation with GSH has been found to restore normal levels of glutathione to the liver, and it has been demonstrated that the treatment has improved such conditions significantly.
Atherosclerosis is a condition of the arteries caused by the deposition of plaques formed from oxidized low-density lipoproteins, otherwise known as bad cholesterol. The strong antioxidant effect of GSH prevents this from LDLs from being oxidized and deposited on the arterial wall. There are other results of glutathione supplementation that indicate the effectiveness of antioxidants in the treatment of serious liver conditions, and there are no doubts that combating the effects of free radicals and oxidizing agents within the liver has a positive effect on many potentially serious liver diseases.
Many of these are exacerbated by the generation of free radicals by relatively modern pollution sources such as pesticides, petrol and diesel emissions, tobacco fumes and various other chemical emissions. A strong antioxidant such as L-glutathione cannot be anything other than an effective means of reducing the biological effect of these oxidants. It protects not only the liver but also the lungs and cardiovascular system.
For all these reasons a supplement consisting of L-glutathione or its constituent parts, glutamic acid, cysteine and glycine, provide significant protection against the stresses and strains of modern living. Increased pollution levels and heightened oxidative stress levels within the body are playing havoc with our body defenses, and GSH is an important one of them that can easily be enhanced by supplementation. There are no known reactions to L-glutathione supplementation, but pregnant women and babies should receive expert medical advice prior to taking it.

Garlic is a member of the lily family, related to onions and chives, and offers many health benefits other than deterring vampires. There is now ample scientific evidence and proof of its beneficial effect on both a healthy immune system and the circulatory system.
The active ingredients in garlic are thiosulfinates, of which the predominant one is allicin, sulfoxides such as alliin and dithiins, of which ajoene is the most widely researched. These compounds are not only responsible for the pungent odor of garlic, but also for its benefits to your health. Among the other components of garlic are selenium, manganese and vitamins B6 and C.
Before considering the other effects of garlic on your health, we shall first consider how it benefits the immune system. The immune system is an essential part of human biology, and protects your body from invasion by pathogenic organisms. Without the immune system your body would rapidly be overcome by bacteria, viruses, fungi, parasites and other foreign bodies, and your body would rapidly fail to function.
The immune system consists of several components that can act in concert to protect you from these foreign invaders. It is too large a subject to be discusses in this article, although its major components are the thymus, the spleen, the lymphatic system, bone marrow, antibodies, and white blood cells of various types. Without it your body would rapidly be broken down to nothing, and would revert to a skeleton in a few weeks.
It is your immune system that causes inflammation, fevers, boils and pus. These are all examples of the immune system at work to protect your body, and even a fever is the immune system raising your body temperature to one that is unfavorable to invaders. Arthritis and hay fever are other examples of how your immune system reacts to invaders, in one case mistaking damaged joint tissue as being foreign and responding by causing inflammation to protect the joint, and in the other a reaction to invading bodies such as pollen.
So what does garlic do to help your immune system? Let's first have a look at the inflammatory reaction of the immune system, a prime example of which is rheumatoid arthritis. The inflammation is caused by compounds known as prostaglandins and thromboxanes, the biosynthesis in your body of which requires the enzymes lipoxygenase and cyclooxygenase (LOX and COX). If these enzymes can be inhibited, then the inflammatory response can be modulated, and LOX and COX inhibition is one of the studies currently being carried out into the treatment of some forms of cancers.
However, where garlic comes in here is that two effective non-reversible inhibitors of LOX and COX are the chemicals Di(1-propenyl) sulfide and ajoene, and both of these are components of garlic. Garlic can therefore be used, not to stop the inflammatory response altogether since it is an essential part of the immune system for certain infections, but to modulate it and protect you from the more severe effects of conditions such as arthritis - both osteo and rheumatoid - and asthma, which is also an immune response.
Allicin has been shown to work with vitamin C to kill certain types of bacteria and viruses, and can help the immune system to protect you from colds and flu, Candida and some gastroenteric viruses. It can also be effective against some of the more powerful pathogens such as tuberculosis. It should be stressed that garlic will not cure these conditions, but help the immune system to deal with them. In fact with respect to the common cold, a study at Munich University has shown that garlic significantly reduces the activity of kappa-B, which is a nuclear transcription factor that mediates the inflammatory response. In other words, the cold symptoms are greatly reduced.
This is significant, since increased kappa-B levels can be triggered off by any pathogen that causes an inflammatory response by the immune system (e.g. infection, allergens, physical trauma). The study showed that unfertilized garlic provided a reduction of 25% in kappa-B activity, while garlic fertilized with sulfur reduced it by 41%.
There have been other studies carried out that demonstrated that Helicobacter pylori, the organism responsible for gastritis and peptic ulcers, was less active in those that took a regular amount of garlic in their diet. This was shown by measuring the antibody concentration, and while H.pylori was found in both sets (with and without garlic in the diet), the antibody count in the garlic-eating set was much lower indicating a significantly lower population of the bacterium.
Another unexpected result was that a group taking both cooked and uncooked garlic had a lower antibody count than those taking either cooked or uncooked. This appears to indicate that cooking changes the chemical nature of garlic, so that both forms work together to provide a more potent effect that cooked and uncooked separately.
What has also been established is that odorless garlic has less of an effect on the immune system that natural garlic, so while the odorless type is more socially acceptable, it is not so good at supporting your immune system. The allicin levels in odorless garlic are very much lower than in the natural bulb.
Garlic has also been found to be able to help with certain types of cancer. Two servings weekly have been found effective in protecting from colon cancer. Allicin has been found to protect colon cells from the toxic effect of various chemicals, and also reduce the growth rate of any cancerous cells that develop. People in Southern Europe consuming large quantities of garlic have been shown to be 39% less liable to contract cancer of the mouth and pharynx, and 57% less liable to contract cancer of the esophagus. It also had an effect on other cancers, including breast and ovarian cancer. However, the effect of onions on such cancers is even greater.
Most people are aware of the cardiovascular benefits of garlic, and it can reduce blood pressure, cholesterol levels and serum triglyceride levels, thus protecting against the harmful condition of atherosclerosis and also of diabetic heart disease. Reduced atherosclerosis means a reduced chance of heart attacks or strokes. It also appears to possess antioxidant properties.
There is no doubt that garlic helps to promote a healthy immune system, although the odorless form appear to be less effective in this respect as natural garlic, and there is evidence that a diet containing uncooked and cooked garlic can be more effective than either of these alone.
L-Glutathione Can Eliminate Toxins in the Liver
December 07, 2007 11:54 AM
L-glutathione is the reduced form of glutathione, and is a tripeptide synthesized in the animal and plant tissues from glycine, cysteine and glutamate. Commonly known as GSH, it contains thiol groups that are maintained in a reduced state, and is a very powerful antioxidant, considered to be the key antioxidant and protective substance in the body.
Glutathione can reduce any disulfide groups in the cytoplasm within the body of the cell, and ensures that the cytoplasm is a strongly reducing medium protecting against oxidation. It has a synergistic effect with other antioxidants to protect the body against free radicals and oxidizing agents that cause so much damage to the body through what is commonly referred to as ‘oxidative stress’. However, there is more to it than that and it attaches itself to toxic chemicals and drugs in the liver and renders them into a state suitable for elimination from the body.
These toxic materials include poisonous pesticides, hydrogen sulfide, carbon monoxide, heavy metals such as mercury, cadmium and chromium and many other substances that we come into contact with due to present day pollution of our atmosphere and foodstuffs. Glutathione can also help protect the body from the effects of chemotherapy and evidence is suggesting possible links with the control of some cancers, diabetes, atherosclerosis and many other degenerative conditions caused by free radical attack and the effects of pollutants.
The way that GSH acts in the cells is that the redox state of the glutathione-glutathione disulfide couple is critical to the health of the intercellular and intracellular fluid. GSH in the reduced state of glutathione reacts with an oxidative agent such as hydrogen peroxide to form the oxidized form, glutathione disulfide and water. It hence mops up oxidizers such as peroxides and free radicals within the cytoplasm of the body’s cells, and also in between the cells. The disulfide is then converted back to GSH by the combined action of the enzyme glutathione reductase and NADPH (the reducing agent nicotinamide adenine dinucleotide phosphate).
The cycle then repeats so that two molecules of glutathione continue to reduce damaging oxidizing agents without themselves being consumed. In so doing, the NADPH becomes oxidized. A continuous supply of NADPH is needed to allow GSH to undergo these biochemical reactions, and up to 10% of our blood glucose is used by the pentose phosphate pathway by which NADPH is synthesized.
Since this cycle consumes no glutathione, it would appear that a supplement is unnecessary. However, this is not the case since the molecule takes part in other reactions in the body, particularly in the elimination of toxic heavy metals from the body. Mercury is highly reactive with the thiol that GSH is, and so will bind to form a stable Hg-sulfydryl bond in the liver. This mercury-glutathione chelate is unable to bind to other proteins or gain access to the body cells, and is eventually harmlessly secreted. The same is true of many other heavy metals that are reactive with thiol’s.
In this way the body is protected from the harmful effects of these heavy metals. However, it results in the loss of the glutathione, and the pollution of modern day living can take a heavy toll of the GSH content of our bodies. For this reason a glutathione supplement is recommended, especially for city dwellers that may be exposed to more heavy metals than those residing in rural areas.
However, the form in which this supplement is taken is very important, because the human digestive tract contains a significant amount of gamma-glutamyltranspeptidase. That is an enzyme which apparently destroys glutathione before it can be absorbed. However, it can be absorbed directly into the bloodstream by dissolving the pill between the teeth and inner cheek. It has also been suggestion that the supplement could be administered by injection.
Others have suggested that rather than administer a supplement, individuals could take other supplements that contain the materials needed to stimulate the formation of GSH. Substances such as vitamin C, selenium (important in GSH biochemistry), methionine, alpha-lipoic acid and glutamine could all help to increase the body’s production of glutathione. A supplement of the constituent parts of cysteine, glycine and glutamic acid should also help. The dosage ranges recommended vary widely from 50mg to 500mg daily, and the effects of supplementation are not yet well know.
Some specific conditions that this wonder antioxidant is useful in treating include liver disease such as hepatitis, cirrhosis and so on. Patients suffering from these diseases show a massive reduction in their GSH content and prior GSH treatment appeared to offer a significant degree of protection in controlled clinical investigations. Patients suffering from chronic hepatitis C have been found to be associated with reduced GSH levels, particularly if also HIV positive.
Similar deficiencies have been noted in some lung conditions such as asthma and other pulmonary conditions. In such cases it has been demonstrated that administration of GSH supplements sufficient to restore normal levels of the substance improved the patients’ conditions by a significant amount. Its effect on atherosclerosis appears to be significant since a decreased level of GSH peroxidase has been recorded in such patients in addition to an increase in lipid peroxides, indicating that oxidation of the arterial wall had been occurring.
Anti-viral therapies that rely on GSH biochemistry for their action have been found to be less effective in those with low GSH levels, and other studies have confirmed that supplementing with GSH improves the response to interferon treatment. These results indicate the activity of oxidizing agents and free radicals in liver conditions, and in fact this has been demonstrated by tests carried out in New York and Philadelphia in the 1990s.
This suggests that the liver is prone to damage by oxidative stress, and that GSH levels may be able to be used as an indication of potential liver disease. What is evident is that a strong case can be made for glutathione supplementation as protection against potential liver, pulmonary and cardiovascular diseases, especially by those exposed to specific polluting agents such as primary or secondary tobacco smoke, auto and diesel fumes and chemicals and pesticides.
L-glutathione is useful, not only for the elimination of toxins in the liver, but also in protecting this large and vital organ from the oxidative stress that modern living brings. L-Glutathione and its precursors are sold over the counter at your local or internet health food store.

Apple Polyphenol (procyanidin B2 and C1) - phytochemical concentrate found in the skin of unripe apples that acts as potent antioxidant. It protects cells against free radicals, reactive atoms that contribute to tissue damage in the body. These chemical compounds are being studied extensively in labs around the world for their health effects in major diseases including treatment of hair growth. Studies showed that after sequential use, an increase of almost 80% of hair diameter and an increase in number of total hairs was shown, with no side effects.
In 2000, Japanese researchers presented their findings to the international community on the hair growth effects of apple polyphenols - specifically one known as procyanidin B-2. They identified two successful compounds- one from chardonnay grapes, and one extracted from unripe apples. The procyanidin B-2 fraction clearly outperformed the grape extract. "Procyanidin B-2 purified from apples," stated the research team, "shows the highest activity of more than 300% relative to controls."
In the same year, in a double-blind placebo-controlled trial, nineteen men with male pattern baldness were studied with a daily topical application of a 1% procyanidin B-2 solution, extracted from apples. Ten other balding men served as controls, receiving a placebo solution. After 6 months, the study concluded:
• The increase in number of total hairs and terminal hairs in the procyanidin B-2 group subjects was significantly greater than controls.
• 78.9% of subjects showed an increased mean value of hair diameter.
• "Procyanidin B-2 therapy shows promise as a cure for male pattern baldness."
Following the revelations, an attempt was made to further understand the mechanism by which the remarkable hair growth effects occurred. The results were published in the prestigious British Journal of Dermatology: Procyanidin B-2, extracted from apples, promotes hair growth: a laboratory study, Br J Dermatol. 2002 Jan;146(1):41-51. In this study, the researchers concluded that procyanidin B-2 acts to diminish protein kinase C isozymes, which play an important role in the hair growth cycle. Procyanidin B-2 seems to promote hair growth by down regulating PKC in both the anagen (active growth phase) and telogen (resting phase) of the hair follicle. When the anagen phase is prolonged, and the telogen phase is shortened, increased hair growth results.
Two more clinical trials and a total of seven published studies have now confirmed the surprising hair growth-promoting effects of apple procyanidins. Here is a summary of those findings:
• Total Number of Hairs: Significantly Increased
• Total Number of Terminal Hairs: Significantly Greater
• Increase in Hair Diameter: 78.9% Positive • Ratio of Thicker (terminal) Hairs: Significantly Higher
• Hair Follicle Activation: Intensive
In the most exciting development yet, Japanese researchers released a new study late in 2005. Once again, procyanidin therapy was proven successful in regrowing hair in subjects with male pattern baldness. The new study, published in the Journal of Cosmetic Dermatology, confirmed the findings of earlier studies, showing clear improvement in the number of hairs and the density of hairs in the treated area. Building on the success of earlier trials, the study was extended to 12 months in the procyanidin group, and proved that longer term procyanidin therapy was even more successful than prior 4 and 6 month trials.
Cooper Peptides - Cooper Peptides have two main properties: (1) potent tissue protective anti-inflammatory agents that limit oxidative damage after tissue injury, and (2) tissue remodeling activation agents, that is, the processes for removal of damaged protein and scar tissue and their replacement by normal tissue. Studies at numerous universities and research institutes have found copper-peptides to improve hair transplant success, increase hair follicle size, stimulate hair growth and reduce hair loss.
Research scientists at the University of San Francisco Wound Center stumbled upon very interesting results. Their discovery was made while applying a synthetically formulated compound, Copper Peptide, to severe wound areas on several patients. During this process something unusual happened. Not only did the wounds heal about 30 percent faster, but a significant stimulation of the follicular cells occurred. As a side effect, these tripeptide complexes actually grew hair around the wound area.
The discovery was so startling that they then applied the same Copper Peptide complex to a female patient who had suffered roughly 90 percent alopecia (hair loss) for years. After about six months of use, she had recovered almost 100 percent of her hair. Dr. Loren Pickart, the leading authority in Copper Peptide technology, describes it as being like a protein injection to the scalp.
Tests were then conducted with chemotherapy patients and recent hair transplant recipients, all with great success in stimulating newer and stronger hair follicles.
Spin traps – are very special compounds that were originally utilized in measuring free radical activity because they react with free radicals both in vitro and in vivo, producing stable complexes. The most commonly used spin trap and the standard which measures new ones is PBN - alpha-phenyl- N-tert butyl nitrone. Hundreds of studies have been conducted over the last ten years that have tested PBN and other “spin traps” in numerous conditions. Later it was discovered that these spin traps had powerful free radical quenching abilities in living systems and could treat a variety of conditions. Spin traps could provide unique protection against free radical damage that complements and enhances the activities of the classical antioxidants such as vitamin C and vitamin E.
Spin traps modulate NF kappa-B regulated cytokines and inducible nitric oxide synthases that are implicated in pro-inflammatory disease conditions. A method for ameliorating a cellular dysfunction of a tissue such as the treatment of hair loss and stimulation of hair growth comprises administering a nitroso or nitrone spin trap to the affected tissue. These agents inhibit the reaction of superoxide and nitric oxide to produce peroxinitrite. Scientists discovered that nitrone and nitroso spin traps have properties in the body for ameliorating cellular dysfunction in tissue attributed, in part, to high energy oxygen and hydroxyl free radicals, and enhancing recuperation of the tissue. Alpha-phenyl-N-tert butyl nitrone (PBN) can be administered, for example, as an anti-alopecia agent to stimulate hair growth.
Spin traps can be administered to the skin to be treated, such as the scalp. Depending on the type of hair loss or alopecia being treated and the conditions thereof, the stimulation of hair growth can usually be obtained by topical application, preferably repeated daily application. The utility of topically applied spin traps is not limited thereto, however, and the stimulation of hair growth can include an increased rate of growth, increased hair diameter, follicular neogenesis, and the like; inhibiting hair loss or alopecia from progressing.
Ketoconazole - Topical ketoconazole shows itself to have an anti-DHT binding effect in the scalp. Nevertheless, it is likely that ketoconazole exhibits other methods to its anti-hair-loss effect. One such theory of ketoconazole anti-alopecia effects may be on its activity upon the removal of sebum, a fatty substance that accumulates in the scalp around the hair follicles. In addition, ketoconazole is an antifungal medication and is significant for people combating hair loss since acting as an antifungal agent it reduces scalp irritation caused by fungal colonization or infection. Reduction of the inflammatory process that occurs in male pattern alopecia is crucial.
If we first examine the role of androgens, specifically dihydrotestosterone (DHT), we find that this hormone has been thought to slowly "choke" the growth of the hair follicle by inhibiting the function of an enzyme in the hair follicle called adenylate cyclase. Suffice it to say that when DHT concentrations remain high in the scalp, we see terminal (thick, coarse) scalp hair become reduced to vellus hair (fine, thin peach fuzz). On March 04, 2001, at the American Academy of Dermatology Meeting in Washington DC, scientists presented the findings of a study done on 1% ketoconazole shampoo which had good news for hair loss sufferers. In the study presented, one hundred male volunteers with mild to moderate dandruff and somewhat oily scalp, were using in a double-blind fashion either a 1% ketoconazole shampoo or a 1% zinc pyrithione shampoo, 2-3 times a week for 6 months.
Analysis of the different parameters set up in the study shows that the hair diameter gradually increased with ketoconazole use (+8.46%) over a 6 month period, whereas the diameter showed a trend to decrease with zinc pyrithione use over the same period (-2.28%). The sebum excretion rate was reduced with ketoconazole (-6.54%) while it increased with zinc pyrithione (+8.2%) over the same period of time. The number of hairs shed over a 24-hour period was reduced by 16.46% with ketoconazole and 6.02% with zinc pyrithione after 6 months. Finally, the percentage of hairs in the anagen phase increased by 6.4% and 8.4% respectively during the study.
The results are similar to a previous study done on 2% prescription strength Ketokonazole where it was shown that use of 2% ketoconazol yielded an increase in hair shaft diameter similar to what was achieved by the control group using 2% Minoxidil and a non-medicated shampoo.
Rooibos - Rooibos or Red Bush Tea - a hardy shrub indigenous to the North Western Cape of South Africa – is an exciting new botanical ingredient with potent antioxidant and anti-inflammatory properties well documented in medical literature. In alternative medicine Rooibos is often prescribed for nervous tension, allergies, stomach and digestive problems. Results from an independent study also showed a significant improvement in hair loss. Studies were initiated at an independent laboratory (Dermascan, France) to study the effect of the use of Rooibos in a hair lotion on a group of healthy persons who were suffering from the problem of hair loss. A 90 day trial was conducted comparing a hair lotion containing Rooibos with a placebo lotion.
After 90 days results showed a significant increase of the hair growth in the lotion containing Rooibos compared with the placebo. An increase in the hair growth was observed with 89% of the volunteers with no undesirable reactions (irritation or allergy). The participants were next asked to fill in a questionnaire. When the results were tallied, 67 percent rated their hair loss as zero or low, 78 percent saw a low to medium improvement, 45 percent saw a low to medium regrowth of hair, and 63 percent considered their hair had become smoother and shinier.
Conclusion: results show that most of the volunteers had a remarkable improvement in both the increase of hair growth and the decrease in hair loss.
MSM - Sulphur is present in protein-rich foods containing high levels of the amino acids methionine and cysteine. These foods include meat, fish, legumes, nuts, eggs, and vegetables, especially onions. However, sulphur has recently become a popular nutritional supplement and topical treatment thanks to the discovery of methylsulfonylmethane, or MSM.
The use of MSM as a nutritional supplement and topical application is relatively recent. An American chemist named Robert Herschler, began studying MSM in 1955. However, another man, Dr. Stanley Jacob with Oregon Health Sciences University in Portland, is considered by many to be the father of MSM. Dr. Jacob found that simple marine life like algae and plankton convert inorganic sulphur to organic sulphur compounds. These compounds are known as dimethylsulfonium salts. These salts are transformed into dimethyl sulfide (DMS), which is released into the atmosphere and is converted by ultraviolet light into dimethyl sulfoxide (DMSO). When DMSO oxidizes, it turns into MSM and is absorbed by plants that become food for animals and humans. MSM is a white, crystalline powder that is odorless and nearly tasteless. When taken as a dietary supplement, MSM proved to have the same health benefits as DMSO without side-effects such as bad breath, itchy skin, nasal congestion, and shortness of breath. Why does MSM help with the development of stronger hair? Various scientific studies have proven that MSM contributes a definite normalizing effect on body functions. The sulfur normally provided to the body by MSM is required for healthy collagen and keratin which are essential for healthy hair, skin and nails. MSM also has proven antioxidant benefits which can disrupt or alter damaging chain reactions of lipid peroxidation in the cell membranes.
MSM has been widely used as a dietary supplement without any reports of allergy or intolerance related to its use. Supplements of MSM are comfortably assimilated without side effects. There are no known contraindications.
Caffeine 4% - Active caffeine ingredient helps to regulate the effects of testosterone levels. Male pattern baldness is known to occur in individuals with sensitivity to testosterone, causing damage to hair follicles that eventually leads to baldness. Caffeine is a xanthine alkaloid compound that acts as a stimulant in humans. Caffeine is a central nervous system (CNS) stimulant, having the effect of warding off drowsiness and restoring alertness.
The independent study at the University of Jena used hair samples from the scalps of young men entering into the first stages of hormone-related hair loss. The study relied on a hair organ culture that used four different types of testing samples. The first was a nutrient-based sample, the second a testosterone only sample, the third was a caffeine only sample and the fourth a mixture of caffeine and testosterone.
According to the research, the results showed that the samples containing the caffeine nutrient helped to stave off hair loss and encouraged new hair growth, while the sample that relied on testosterone only led to increased hair loss. But perhaps the most impressive was the testosterone and caffeine sample, which helped to prevent further hair loss.
The results showed that using the caffeine treatment average growth was increased by around 46 per cent and the life cycle of the hair was extended by 37 per cent, when compared to the control study.
Carnitine Tartrate - L-Carnitine, a vitamin-like nutrient, occurs naturally in the human body and is essential for turning fat into energy. Active energy metabolism is an essential prerequisite for the growth of strong and healthy hair. In biological systems ATP acts as the universal energy currency. One of the most potent bio-actives that significantly increases cellular ATP content is carnitine tartrate.
Statistical evaluation demonstrated a significant increase in ATP equivalents in human hair roots treated with carnitine tartrate, showing that carnitine tartrate is an ideal ingredient for hair care formulations, providing energy for the optimal environment to produce strong and healthy hair. Throughout the test period ATP content within plucked hair follicles was determined twice daily using a commercially available test kit. Statistical evaluation of baseline adjusted values demonstrated a significant increase in ATP equivalents in human hair roots treated with carnitine tartrate. These effects were absent in the placebo group, thus underlining the stimulating activity of carnitine tartrate.
The outstanding bio-activity of carnitine tartrate was furthermore demonstrated in a second study, assessing the effects after a single application of a shampoo formulation supplemented with carnitine tartrate. Again, ATP levels in plucked human hair follicles were significantly increased.
Amino Acids: Ornitine, Taurine, Cysteine - Amino acids are the building blocks of protein, from which hair is created. They are assembled in the correct sequence by stem cells to form keratin, a complex and immensely strong hair protein. Vital amino acids have to be replaced consistently, as damage is accumulated over time. We can replace a combination of these lost amino acids directly into the hair, where they are shown to provide significant tensile benefits to the hair shaft.
Hair is composed primarily of proteins (88%). These proteins are of a hard fibrous type known as keratin. Keratin protein is comprised of what we call "polypeptide chains.” The word, polypeptide, comes from the Greek word "poly" meaning many and "peptos" meaning digested or broken down. In essence, if we break down protein, we have individual amino acids.
Many (poly) amino acids joined together form a "polypeptide chain". Two amino acids are joined together by a "peptide bond", and the correct number of amino acids placed in their correct order will form a specific protein; i.e. keratin, insulin, collagen and so on. The "alpha helix" is the descriptive term given to the polypeptide chain that forms the keratin protein found in human hair. Its structure is a coiled coil. The amino acids link together to form the coil and there are approximately 3.6 amino acids per turn of the helix (coil). Each amino acid is connected together by a "peptide bond". The peptide bond is located between the carbon atom of one amino acid extending to bond with the nitrogen atom of the next amino acid. In many individuals the extremities, including the top of the head, are the most difficult places to maintain blood flow. Follicles which are constantly deprived of blood, and therefore nutrients, cannot produce hair properly. Lack of proper nutrients, amino acids, minerals and vitamins can certainly hamper hair growth.
L-Arginine is a semi-essential amino acid synthesized by the body from L-Ornithine. Arginine + Ornithine support protein synthesis because they are involved in the transport and storage of nitrogen. The usage of taurine corrects the "rigidification" of the connective sheath that surrounds the Pilosebaceous unit and hair follicles, specifically those affected by pattern hair loss. This is a novel and previously undisclosed angle on hair loss treatment that has yet to be touched upon in any of the medical literature or prior publications.
The amino acid, l-cysteine speeds up hair growth and increases hair shaft diameter resulting in fuller hair. L-cysteine has been reported to facilitate longer hair growth, beyond what is genetically programmed. L-cysteine also provides potent antioxidant protection to the hair follicle. Users of topical n-acetyl-cysteine have reported hair regrowth.
Emu Oil - The emu, dromaius nova hollandiae, is a flightless bird part of a group called ratites which also includes the ostrich and the kiwi. Modern Australians learned early on from the Aborigines the many valuable qualities in the emu and its oil. The earliest research studies in emu oil come from Australia, and Australia continues to export emu oil to this day.
In the United States today there is a growing network of research labs interested in emus and their incredible oil. Emu oil is rendered from a thick pad of fat on the back of the bird that was apparently provided by nature to protect the animal from the extreme temperatures in its Australian homeland. Emu oil is deep penetrating and super hydrating to the skin - an all-natural tissue nutrient. Michael Hollick, MD, Ph.D., Professor of Medicine, Physiology, and Dermatology at Boston University School of Medicine conducted a study involving emu oil and hair growth. His study found that there was a 20% increase in growth activity of skin that received emu oil compared to skin that received corn oil. Looking at the hair follicles Dr. Hollick realized they were much more robust, the skin thickness was remarkably increased suggesting that emu oil stimulated skin growth and hair growth. Additionally, the study showed that over 80% of hair follicles that had been "asleep" were woken up, and began growing.
Emu oil is anti-inflammatory, which may be in part why it stimulates hair growth. Emu Oil has also been shown to be a 5 alpha reductase inhibitor in target tissues when topically applied, which likely contributes significantly to its hair growth properties. A third important property of emu oil is that it is bacteriostatic.
Emu Oil contains a multitude of Essential Fatty Acids (EFA) which helps to "feed" the skin. Consumers who suffer from natural forms of baldness have reported hair re-growth. Since Alopecia Areata only suppresses the hair follicle (vs. killing the hair follicle), emu oil may have an effect to assist with hair regrowth.
Biotin – Biotin is a member of the B-vitamin family and a major component in the natural hair manufacturing process -- it is essential to not only grow new hair, but it also plays a major role in the overall health of skin and nails. The beneficial effects of biotin on hair may be linked to its ability to improve the metabolism of scalp oils. Biotin when absorbed by the scalp may promote hair growth and it is able to penetrate the hair shaft making it expand which actually thickens the hair cuticle.
Biotin is used in cell growth, the production of fatty acids, metabolism of fats and amino acids. It plays a role in the Krebs Cycle, which is the process in which energy is released from food. Biotin is so important to hair health, that many dermatologists prescribe biotin supplements to their patients as part of their medical treatment for hair loss.
After applying Revita with a gentle massage, you should leave it on the scalp from 1 – 2 minutes before rinsing. Then repeat and leave on the scalp for 3 – 5 minutes. If desired, follow with a high quality conditioner. For optimal results, Revita should be used at least 5 times per week.
This formulation is contraindicated in individuals with a history of sensitivity reactions to any of its components. It should be discontinued if hypersensitivity to any of its ingredients is noted.
Q. Is Revita safe ?
A. Revita primarily contains compounds that are not only safe in topical use, but actually dramatically enhance overall skin health. The other active ingredients such as Ketoconazole have been tested in clinical studies and have been shown safe.
Q: Can I use hair sprays, mousses, gels, etc.?
A: Hair spray, gel, and other styling aids are not recommended since they tend to clog the hair shaft. However, you can use them while using Revita.
Q: Can I have my hair colored or permed while using Revita ?
A: While there is no evidence that coloring or perming hair can lead to or even worsen hair loss, it is generally not recommended for people with hair loss. If you are experiencing hair loss then perming and coloring hair is not recommended. However, this will not interfere with Revita.
Q: What is SLS/SLES free ?
A: SLS means Sodium Lauryl Sulfate and SLES means Sodium Laureth Sulfate, commonly used low cost detergents in shampoos and cleansers. They are linked to skin irritation, skin drying and hair loss due to follicle attack. Revita is Sodium Lauryl Sulfate and Sodium Laureth Sulfate free, and that means that Revita does not irritate you scalp and preserves your hair follicale health.
Q: Can I blow dry my hair after using Revita ?
A: Extreme heat damages the proteins in the hairs making them fragile. Nevertheless, if you need or want to blow dry your hair, you can do it after using Revita.
Q: Who is a candidate for Revita ?
A: Ideal candidate is someone with little hair loss or at the beginning stages of hair loss, since it is much easier to prevent hair loss then to grow new hair. Someone who is concerned with hair loss prevention should start using Revita immediately.
Q: What type of results should I expect with Revita ?
A: When deciding to use Revita, it is important to have realistic expectations. Depending of severity and duration of your hair loss, it could take some time to see hair growth. In fact, during the first 2 weeks of treatment you may actually notice increased hair loss as old hairs are being pushed out and the hair follicles start growing new hair. Do not become alarmed with this and just stick to the treatment.
Q. Does Revita have any systemic side effects ?
A. No, when used as directed, Revita active ingredients have a long history of use both orally and topically.
Q. Does Revita work for women?
A. Yes. In most cases, the cause of hair loss in women is surprisingly similar to men. Fortunately for women, estrogen helps to protect the hair follicle from the destructive effects of DHT. However, many women develop thinning hair and loss due to fluctuation of estrogen levels and/or over production of DHT. Revita can help protect the hair follicle from DHT resulting in a thicker, fuller and healthier hair.
Q. I am using other topical treatments. Can I use Revita at the same time ?
A. Yes. Revita has no side effects and does not cross react with other topical treatments. You can safely opt to use Revita with other products, and we strongly recommend the association with Spectral.DNC for more severe hair loss or Spectral.RS for thinning hair.
Q. Do I need to use Revita for a long time ?
A. Once you have reached the desired results, you should continue to use Revita as your regular shampoo to maintain the revitalized hairs and a healthy scalp.
Q: Is stress a factor in hair loss?
A: When the body is under significant physical and emotional stress it is possible that the immune system will produce anti-bodies that attack hair follicles, and this results in bald patches or diffuse loss. Stress-induced loss will respond very well to Revita and you should keep using Revita as your regular daily shampoo to keep your scalp healthy.

HIGH BLOOD PRESSURE AND GARLIC THERAPY

HIGH BLOOD PRESSURE AND GARLIC THERAPY
Garlic has been used for generations in China and Japan for as a traditional medicine for hypertension. Even today, it continues to be a popular remedy for a disease that has become an epidemic in the western world. Taking a daily dose of garlic can result in a 12 to 30 mmHg reduction is systolic blood pressure and a 7 to 20 mmHg reduction in diastolic pressure in people who suffer from essential hypertension.12
One scientific study revealed that 40 out of 100 patients with high blood pressure experienced a reduction of 20 mmHg or more after a week of garlic treatment.13 Apparently, rabbits and humans who have been tested with garlic have demonstrated a rapid and continued decrease in blood pressure. One reason for this is that garlic seems to dilate blood vessel walls.14 It is the methyl allyl trisulfide contained in garlic which creates this action. Evidently, the effectiveness of using garlic for high blood pressure is dependent to some extent on the type of garlic used. Bulgarian studies suggested that aged Garlic extracts were more effective although this view has been subject to debate. Most practitioners who use garlic for their hypertensive patients recommended a high dosages initially.
In 1992, an article in Planta Medica, a German scientific journal, suggested that gamma-glutamyl-S-allyl-cysteine, a peptide found in Garlic, inhibits a certain enzyme which is involved in the conversion of certain hormones that actually regulate blood pressure. Angiotensin I does not raise blood pressure, however, Angiotensin II can. The peptide found in garlic inhibited the enzyme that changes Angiotensin I into Angiotensin II.15 Consequently, blood pressure levels dropped.
In addition to the actions discussed above, the ajoene compounds in garlic also help to prevent high blood pressure by inhibiting the tendency of blood cells to adhere together and create clots. Garlic oil can increase the breakdown of fibrin by over 100 percent in humans.16 When the blood is discouraged from clotting, blood flow is not restricted, therefore, blood pressure does not rise. Some people who have been on hypertensive drugs have gradually been able to wean themselves off using garlic. If you decide to use garlic for high blood pressure, make sure you check with your doctor and do not abruptly stop taking your medication. (Note: People who have abnormally low blood pressure need not avoid eating garlic. There is evidence to suggest that hypotension benefits from the therapeutic effects of garlic as well as hypertension.
Considering these findings, it would seem that garlic acts to normalize blood pressure whether it be high or low, an action which prescription drugs cannot accomplish.)

The Latest Breakthroughs in Garlic Research
on Cancer and Cardiovascular Disease
Presented at the 2005 World Garlic Symposium
Many of the world’s top-level scientists gathered in Washington D.C. this week for the 2005 Garlic Symposium, entitled, “Significance of Garlic and its Constituents in Cancer and Cardiovascular Disease.” The conference provided current scientific information about the effect of garlic and its constituents on health and performance. The symposium was held at the Georgetown University Conference Center on April 9-11, 2005.
“For the first time in seven years authorities in various fields of garlic research from all over the world to provide the latest updates, specifically regarding aged garlic extract and its actions in diseased states including heart disease and cancer,” commented Dr. Matthew Budoff, M.D. cardiovascular researcher at UCLA. “Garlic has been used medicinally for thousands of years in virtually all ancient cultures. Now, new metabolic roles for garlic are being proposed and there are many promising lines of research.”
Presentation highlights included:
Effect of aged garlic extract (AGE) has been tested in the placebo-controlled double blind randomized clinical study that determined that the atherosclerotic plaque burden detected by electron beam tomography (EBT) changed significantly with the use of aged garlic extract, Patients in Dr. Budoff’s study were able to significantly lower their total cholesterol, blood pressure, homocysteine and LDL cholesterol oxidation levels with aged garlic extract supplementation.
“Garlic is turning out to be a major player in cancer and heart disease prevention and control, especially in combination with drug treatments,” said Richard Rivlin, M.D. of Strang Cancer Prevention Center at Cornell. “It’s also showing us that we can start early. It’s madness to treat cancer and heart disease in their advanced stages. We need to start early and aged garlic extract is an excellent way to do that.”
Almost 400 scientific studies have been completed on aged garlic extract, done in major universities worldwide. These studies have focused on a variety of heart disease risk factors such as cholesterol, high blood pressure, homocysteine levels, inhibiting LDL oxidation, anti-platelet aggregation and adhesion, stimulating blood circulation; in addition to other studies on immune stimulation, cognitive effects, liver function and anti-tumor effects. .
PRECLINICAL PERSPECTIVE ON GARLIC AND CANCER. John A. Milner, National Cancer Institute, Rockville, MD 20892
Mounting evidence points to the anticancer properties of fresh garlic extracts, aged garlic, garlic oil, and a number of specific organosulfur compounds from garlic. These prevention characteristics arise through both a dose and temporal related change in several cellular events including those involving drug metabolism, immunocompetence, cell cycle regulation, apoptosis and angiogenesis. A block in carcinogen activation through modulation of cytochrome P450-dependent monooxygenases and/or acceleration of carcinogen detoxification via induction of phase II enzymes likely account for some of this protection. The block in preneoplastic lesions and/or tumors in several sites suggests a generalizable mechanism. The efficacy of water- and lipid-soluble allyl sulfur compounds against chemical carcinogenesis appears comparable, although more studies are needed. A shift in sulfhydryl groups, redox status or enzyme catalysis may account for some of the phenotypic changes. They may also account for the observed hyperphosphorylation of specific cell cycle related proteins and histone hyperacetylation; both of which have been correlated with suppressed tumor cell proliferation. Several forms of allyl sulfur compounds are effective in blocking cell division and inducing apoptosis, but notable differences in the efficacy among these various compounds and across tumor types are evident. While the expression of many genes and proteins can be influenced by allyl sulfides; the challenge is to determine which is responsible for a phenotypic change. Additional studies are needed with more modest exposures and over prolonged periods and that utilize transgenic and knockout models to assist in the identification of molecular targets. Finally, additional research is needed to identify sensitive “effect” and “susceptibility” biomarkers that can ultimately be used to identify responders from non-responders.
INHIBITION OF CORONARY ARTERIAL PLAQUE ACCUMULATION BY GARLIC. Matthew Budoff, Harbor-UCLA Medical Center, UCLA School of Medicine, California, USA
Effect of Aged garlic extract (AGE) has been tested in the placebo-controlled double blind randomized clinical study to determine whether the atherosclerotic plaque burden detected by electron beam tomography (EBT) will change at a different rate under the influence of AGE or placebo. EBT can non-invasively quantitate the amount of coronary calcification and track atherosclerotic plaque over time. Nineteen of 23 patients completed the study protocol. The patients were well matched for age, gender, statin use and cardiac risk factors. Patients underwent EBT and blood testing at baseline, and then again after 12 months of randomization. The average change in the calcium score (Volumetric method) ± SD for the AGE group (n = 9) was 7.5 ± 9.4% over the one year. The placebo group (n = 10) demonstrated 22.2 ± 18.5% annual progression, significantly greater than the treated cohort (p = 0.01). While there were no significant changes in cholesterol parameters, or C Reactive protein between the groups, high density lipoproteins and plasma homocysteine in the AGE group demonstrated a trend toward improvement compared to the placebo patients. Thus, although this is a small-scale trial, it demonstrates the potential of AGE to inhibit the rate of atherosclerosis (progression of coronary calcium), as compared to placebo over one year. Larger studies need to be performed to assess this potential anti-atherosclerotic therapy and the impact on coronary events.
INFLUENCE OF GARLIC ON ENDOTHELIAL DYSFUNCTION IN HYPERHOMOCYSTEINEMIA. N. Weiss, N. Ide, T. Abahji, L. Nill, C. Keller, U. Hoffmann. Klinikum der Universität München, D-80336 Munich, Germany
Endothelial dysfunction (ED) due to decreased bioavailable nitric oxide (NO) by increased vascular oxidant stress plays a critical role in the vascular pathobiology of hyperhomocysteinemia (hhcy). Aged Garlic Extract (AGE) minimizes intracellular oxidant stress and stimulates NO generation in endothelial cells. We performed a placebo-controlled, blinded, cross-over study to examine whether AGE prevents macro- and microvascular ED during acute hhcy induced by an oral methionine challenge in healthy subjects. Acute hhcy leads to a significant decrease in flow-mediated vasodilation of the brachial artery as determined by vascular ultrasound, indicative of macrovascular ED, as well as a decreased number of recruited nailfold capillaries during postischemic reactive hyperemia as determined by videomicroscopy, and to a decreased ratio of acetylcholine (endothelium-dependent) vs. sodium nitroprusside (endothelium-independent) iontophoresis induced skin perfusion as measured by laser doppler flowmetry, indicative of microvascular ED. Preliminary results show that pretreatment with AGE for six weeks diminishes the adverse effects of acute hhcy on endothelium-dependent brachial artery vasodilation and on acetylcholine-induced stimulation of skin perfusion. Whether or not this is accompanied by changes in biochemical parameters of ED is still under investigation. It is concluded that AGE may at least partly prevent a decrease in bioavailable NO during acute hhcy.
