Oolong tea inhibits the growth and progression of breast cancer cells
May 08, 2019 03:07 PM
Many persons drink tea for relaxation, stress relief, and to get a caffeine fix but little do they know that drinking tea can help to inhibit the growth of breast cancer cells. Some researchers in both America and China who worked together have found that drinking tea can lead to DNA damage in the cells of breast cancer. Since this tea can be used to prevent also the progression of a tumor, it is hoped that one day they can be a non-toxic means to prevent the growth of breast cancer. In the USA alone, about 250,000 women were diagnosed with breast cancer in 2018 and about 41,000 are expected to die from the disease. Although there are improvements in the screening for breast cancer, and in treatment, it is noted that more needs to be done to help women. The researchers discovered that tea has long been used in medicinal treatment in China for centuries and reckoned that black tea is used more often than green tea and oolong tea. And although the benefits of green tea in treating cancer has long been known, the use of oolong tea for cancer is not known, so the researchers sought out this tea in their experiment. Using patients from Fujian, China, where oolong tea is grown mainly, they found out that there was a lower incidence of cancer among people who take oolong tea.
"Like black and green teas, oolong tea contains several vitamins, minerals, and helpful antioxidants."

Fight Free Radical Damage From Toxins With Vitamins And Herbs
July 28, 2010 11:34 AM
There are many things that destroy the immune system. Each day we are bombarded with them in many forms. The following are some of the most common ones that are encountered.
Agene, also known as Nitrogen Trichloride, is used to bleach flour and give it a white appearance. Unfortunately, it can cause epileptic-like fits along with failure of muscle coordination. Excessive use of alcohol also severely impairs the immune system. It increases susceptibility to infection and weakens the central nervous system. Alcohol promotes chronic lung disease, malignancies of the neck and head, intestinal problems, hypoglycemia, diabetes, liver disease, and a whole variety of other problems. B vitamins, folic acid, niacin, vitamin E, magnesium, zinc, and protein are depleted by alcohol. All of these nutrients play a huge role in immune health. Aspartame breaks down in the digestive tract into a toxic material known as methanol. In order to prevent methanol from metabolizing into formaldehyde, a poison, a person needs to take another poison, ethanol.
Glutamic acid is a substance that is found in monosodium glutamate, a flavor enhancer. It affects the central nervous system and can trigger depression, gloomy fantasies, and rage for as long as two weeks following the ingestion of monosodium glutamate. High-diet fat intake increases the levels of bile acids in the colon. This breaks down into deoxycholic and lithocholic acids, both of which are cancer-causing elements. This can cause cancer of both the colon and the rectum. A diet that is high in animal protein and fat can cause cancer of the pancreas, breast, gallbladder, ovaries, uterus, prostate, and leukemia. Junk food such as sweets, white flour, and white sugar products, put a double amount of stress on the body. When too much junk food is eaten, the appetite for good, wholesome food is dulled.
Caffeine decreases immunity in the body, with fibrocystic breast disease being connected with the consumption of foods that contain caffeine. It is often caused by the chemicals methylxanthine, theophylline, and theobromine, which are found in coffee, black tea, cola drinks, chocolate, and other soft drinks. These elements act on hormones that cause breast tissue to develop fibrocystic lumps. Caffeine takes away the body’s own use of iron and inositol, and is often suspected of causing cancer in the pancreas.
Food dyes and flavorings are the culprits in behavioral problems that occur in children and adults, with some of these problems being learning disabilities and hyperactivity. Sodium nitrate is a preservative that is often found in cured meats like hot dogs, bologna, and ham. It has the potential to produce permanent epileptic changes in brain activity and damage the central nervous system.
High protein diets can deplete calcium in the body, especially when the source of protein is an animal product. There are concentrated doses of hormones and antibiotics that are found in beef which suppress the immune system and promote tumor growth. Poly-unsaturated fats undergo a process that produces rancidity in oils. This process releases dangerous free radicals, which eventually lead to cancer.
Heavy metals like lead and mercury can cause serious damage to the nervous system, with even small amounts being considered toxic. Lastly, the wide use of vaccinations and antibiotics is considered to be one of the main causes of immune system disorders.
Our bodies are under constant attack by our toxic environment. Fortunately, with regular vitamin and herb use, one can help the body restore its immune system to proper function so we can live a happier healthier life.

Kombucha is also known as Manchurain tea or mushroom. It is not an official member of the fungi family. Actually, it is a symbiotic culture of genus Saccharomyces yeast and xylinum bacteria. Kombucha dates back as far as two thousands years in East Asia. Originally, it was used for healing in Japan, China, and Korea. Kombucha use spread with the beginning of trade. Merchants took the kombucha plant to Russia and then to Eastern Europe. Although it is not technically a fungus, it contains many similar healing properties. Because of this, it is often recommended along with members of the mushroom family.
This herb is usually placed in a nutrient solution of distilled water, black tea, and sugar. The process of brewing kombucha was introduced in Russia and Ukraine at the end of the 1800s. However, it did not become popular until the early 1900s. The kombucha culture is known locally as chayniy grib and the drink itself is referred to as grib, tea kvass, or simply kvass. Then, it undergoes chemical changes which make it beneficial for human consumption. The chemical reactions that occur in this process are very complex. The kombucha feeds on sugar, thus producing glucuronic acid, lactic acid, vitamins, amino acids, and some antibiotic solutions.
The healing properties are thought to be due to the production of glucuronic acid, B-complex vitamins, C vitamins, and lactic acid. Like all foods, there must be some care taken when preparing and storing kombucha, or else contamination may result. Keeping this herb safe and contamination-free is a concern to many home brewers. Key components of food safety when brewing kombucha include a clean environment, proper temperature, and low pH.
Russian studies have uncovered the presence of substances in the kombucha tea that contain antibiotic properties. The tea was found to prevent the growth and colonization of other yeasts and bacteria. The kombucha plant is also believed to help with a wide variety of conditions. It seems to have a detoxifying effect on the entire body, which makes it extremely beneficial for invigorating the whole body.
Research done in Germany led by Dr. Valentin Koehler found that kombucha has the ability to increase the function of the immune system. It does this by boosting levels of interferon. Kombucha contains many different cultures along with several organic acids, active enzymes, amino acids, and polyphenols. Due to the acidic fermentation process used in it’s brewing. Kombucha contains ethyl alcohol in amounts that vary from 0.5% to 1.5%. The range depends on the anaerobic brewing time and proportions of microbe. Commercial preparations of this herb are typically 0.5% in order to comply with distribution and safety procedures.
The entire kombucha plant is used to provide antibacterial, antibiotic, antifungal, and immuno-stimulant properties. Primarily, this herb is extremely beneficial in dealing with immune deficiencies and effects of toxins. In order to obtain the best results when supplementing with this, or any herb, it is important to consult your health care provider before beginning any regimen while on medications. For more information on the many beneficial effects provided by kombucha, please feel free to consult a representative from your local health food store with questions.
Polyphenols is an Antioxidant
October 13, 2008 02:14 PM
A lot of new evidence suggests that consuming more plant polyphenols is a powerful way to protect aging arteries. These polyphenol compounds help improve endothelial function, a critical factor in preventing atherosclerosis; inhibit abnormal platelet aggregation which causes most sudden heart attacks and strokes; fight inflammation; and support healthy blood lipids. Polyphenols that are of particular interest are those derived from green tea, cocoa, apples, and black chokeberry, which all complement each other in helping to build the body’s defenses against various ailments.
All throughout history, the medicinal potential of plants has been celebrated. Modern science has found that edible plants are to be valued for their high vitamin and fiber along with their rich store of polyphenols. Polyphenols are found in fruits and vegetables, as well as cocoa, tea, and chokeberry and have been shown to be a type of chemical that may protect the body against some common health problems as well as certain effects of aging. Polyphenols protect cells and body chemicals against damage that is caused by free radicals and block the action of enzymes that cancers need for growth, deactivating substances that promote the growth of cancer. The increased consumption of polyphenols has been associated with a reduced risk of cardiovascular disease and potentially cancer and stroke.
In Aztec culture, cocoa was one of the most highly prized due to its medicinal and stimulant value, along with its taste. The polyphenols found in cocoa occur in a higher concentration than can be found in any other food. They also have antioxidant activity much greater than those found in broccoli or red wine. The catechins and procyanidins that are found in cocoa seem to lower the risk of cancer and heart disease. Cocoa has also been proven in studies to reduce blood pressure, improve insulin sensitivity, and slightly ameliorate the lipid profile. Although cocoa is a healthy and tasteful food, it is high in caloric content and therefore, its ingestion must be accompanied by the careful reduction of calories from other sources.
Many studies have shown that tea polyphenols can be extremely beneficial to human health, possessing anti-obesity, antihypertensive, anti-diabetic, antioxidant, anti-inflammatory, and anticancer effects. Tea is the world’s second most consumed beverage, although less popular in the Western diet. Green tea and white tea retain more polyphenols in their intact form, as oolong and black teas undergo more extensive processing before they are marketed. Tea polyphenols break down in high temperatures therefore; freshly brewed tea contains a higher amount of polyphenols per serving than do tea drinks that are canned or bottled.
Similar to the blueberry, the black chokeberry is high in anthocyanins and antioxidant activity. It is native to eastern North America and has become popular in Eastern Europe and Russia due to its health-promoting potential. This berry protects the liver from chemical poisoning and the stomach lining from ulcers. It also acts as an anti-inflammatory, lowers harmful cholesterol levels, and prevents dangerous swings in blood pressure. Some studies have shown that this berry seems to prevent the harmful mutations in cell cultures, regulates immune function of human white blood cell cultures, and suppressed the growth of human colon cancers.

Kombucha is a mushroom like substance made up of a group of yeasts and bacteria. It is a symbiotic colony of several cultures, which include genus saccharomyces yeast and xylinum bacteria. Used in East Asia as far back as 2,000 years ago, Kombucha was originally used for healing in Japan, China, and Korea, with its use spreading when European trade began. Merchants took the herb to Russia and then to Eastern Europe. Although it is not technically a mushroom, kombucha has many similar healing properties, which makes it often recommended along with other members of the mushroom family.

Kombucha feeds on sugar-producing glucuronic acid, lactic acid, vitamins, amino acids, and some antibiotic solutions. The healing properties that are associated with kombucha are thought to come from the production of glucuronic acid, vitamins B-complex, vitamin C, and lactic acid.
Russian research has found that substances in kombucha tea contain antibiotic properties. These properties prevent the growth and colonization of certain yeasts d bacteria. There is a group of organisms in kombucha that contain usnic acid, which has shown possibilities of being responsible for the antibiotic activity that kombucha provides.
The most important function of kombucha is its ability to detoxify the body, as it is virtually impossible to avoid contact with some forms of toxins on a daily basis. A buildup of these toxins can result in many forms of illness. Keeping the body as clean as possible is essential for health. Kombucha helps us achieve a clean and health state because it works on the entire body to clean toxins from the system. It is also helpful to the support and strengthening of the glandular system. Additionally, it has been found to be useful for conditions including cancer, arthritis, fatigue, constipation, gout, multiple sclerosis, and arteriosclerosis.
Kombucha has been proven to be helpful in a wide variety of conditions. It has a detoxifying affect on the entire body, which allows for it to be beneficial in invigorating the entire body. It does not seem to specifically work for individual diseases, but it does work on cleansing the body as a whole, so that it may more effectively fight disease. Once toxins are eliminated, the body is able to better heal itself.
German research under the supervision of Dr. Valentin Koehler has discovered that kombucha possesses the ability to increase the function of the immune system, as it boosts the levels of interferon. The detoxifying abilities that kombucha holds allows it to help the body in working more effectively in fighting disease keeping one healthier.
Many remedies of great value are offered from the plant kingdom, with medicinal mushrooms turning out to be one of the richest offerings. Mushrooms can help to heal naturally and gently, without the toxic side effects that most synthetic drugs have. The use of mushrooms is beginning to grow thanks to increasing evidence of their healing potential. They stimulate the immune system and aid the body in preventing and healing illness. Kombucha is a mushroom like substance which has been used by eastern healers for thousands of years, and is now making its way into the western world.

Tea is soaked in culture and history, with its roots dating back to ancient China. Chinese legend says that tea was created more than 5,000 years ago when the leaves fell into the boiling water of an early emperor. From there, tea has become a popular drink, with a culture of its own. True teas are made from the dried leaves of the tea plant, which was first cultivated in China and found growing wild in India. The different processing techniques are used on the leaves of the tea plant in order to produce the many different styles. Green tea is produced by steaming the fresh-picked leaves, followed by heat-drying, while black tea is made by allowing the tea leaves to ferment completely before firing. Oolong teas are made by partially fermenting the leaves before firing while white tea is the least processed of all the teas, with it not being oxidized or rolled by instead, dried by steaming.
Anything that doesn’t come from the Camellia sinensis plant is known as an herbal tea. Herbal teas contain herbs and spices that are often used for health purposes. Rooibos, which is the popular herbal tea, is also referred to as red tea, is full of polyphenols and flavonoids which help reduce cellular damage that is caused by free radicals which weaken natural defenses. Red tea also contains many beneficial vitamins and minerals and helps to reduce cramping and gas.
Other herbal tea blends are made for various symptoms such as PMS, energy, weight control, and detoxing. An herbal tea blend that is comprised of astragalus, cranberry, rooibos, and three types of Echinacea can help to support the body’s natural defense system. Peppermint blend teas alleviate digestive disorders and insomnia, while Holy Basil tea helps to alleviate stress, lowers cortisol levels, and promotes a sense of well-being. All ingredients in an herbal tea have a purpose. The herbs and spices improve well-being and contribute to an active, balance, and healthy lifestyle.
A quality herbal tea looks at several aspects of the ingredients. Each herb is looked at for its medicinal value before being included in a tea. Higher quality herbs mean that a higher price is paid for the starting bulk materials, making the price of the finished tea product more expensive. Where the herbs are grown, how they are grown, and how they are harvested are all very important pieces of information to tea makers, who all want the best quality available for their tea formulas. The most important fact to tea makers is that the herbs are organic, and if they’re not organic, that they are wild-crafted, meaning that they go through quality control procedures to make sure that there are no chemical pollutants, heavy metals, or toxins in them.
Finally, the cut of the herbs is also especially important when creating teas, with tea bag cut producing the most effective single serving healthful tea. A tea bag cut means that they are small enough to be broken down and extract all the valuable components are able to be extracted out of the herbs in the shortest amount of time. Herbs should also be large enough that they don’t pass through the filter bag and leave residue in the cup. Herb quality and freshness is also very important, with the color of the herbs being vibrant and the smell obvious.
Fight Histamine With Quercetin
February 11, 2008 03:48 PM
Quercetin is one of the more powerful of the body’s antioxidants, and it can also be used to reduce the rate of histamine release by the body normally initiated by contact with an allergenic substance (for which your immune system has designed an antigen). We shall examine the biochemical mechanism which this is achieved, but first let’s have a closer look at quercetin and what it actually is.
Quercetin is what is known as a phytochemical, which is simply the scientific name for a chemical that is naturally produced by plants. Other phytochemicals include vitamin C and omega 3 fatty acids, so the term is very broad ranging for any substance that is produced by plants. It is commonly known as a flavanol, one of a family of compounds known as flavonoids that give color to plants.
It is a very active flavonoid, with very powerful antioxidant properties, in addition to acting as an anti-histamine and anti-inflammatory. Histamine is an amine released as part of the body’s immune response to allergenics, and quercetin inhibits its manufacture and release. This amine is an irritant and can itself cause inflammation and the other symptoms associated with allergies such as runny and itchy eyes, a stuffy nose, sneezing and itchy spots. Quercetin can be used to alleviate these symptoms by blocking the manufacture in the body of the histamine that causes them.
It demonstrates other anti-inflammatory properties such as alleviating the symptoms of arthritis, and also helps to destroy free radicals in the body through its strong antioxidant properties, but before we discuss how it does this we shall have a closer look at the mechanisms used in its effect in inhibiting histamine.
Calmodulin is a protein that is used to transport calcium ions, Ca++, across the membranes of certain cells in the body, and by doing so it helps to mediate a number of biochemical processes within the body, among them the immune response and inflammation. It should not be thought these are always unwelcome responses: on the contrary, they are the body’s way of reacting to foreign bodies and preventing more serious conditions from developing.
However, there are instances where the body can become sensitized to certain substances and overreact to their presence leading to conditions such as hay fever or, considerably more serious, asthma. These are just two of the undesirable manifestations of the human immune system that we would be better without. What quercetin does is to prevent calmodulin from properly binding to certain enzymic proteins and so suppress the effect of these proteins. Among these are the enzymes that control the secretion of histamine from mast cells.
Mast cells are found mainly in areas prone to injury and at the interface between internal tissues and outside world, such as the nose, mouth, lungs, eyes, blood vessels and feet. They contain granules rich in histamine that degranulate and released the histamine when the immune system detects foreign bodies such as pollen grains and dust mites, especially when the body has created antigens against them.
Quercetin suppresses the release of histamine from the granules in the mast cells by preventing the degranulation. The release of the histamine is not completely halted, but its effects are reduced and quercetin is used in the treatment of asthma where it is believed to help reduce the symptoms by reducing histamine-induced swelling in the airways.
A similar application of this flavonoid is in reducing the inflammatory response to arthritis, the main cause of the swelling of this painful condition. Your skin can also be affected by inflammation that is partially controllable by quercetin. Collagen and fibronectin biosynthesis is increased that help to maintain not only healthy joints, but also to speed up the healing of wounds and repair damaged nerves. It is also believed that quercetin can hold back the effects of aging on the skin, and slow down the formation of wrinkles.
There are other applications of this versatile flavanol, including its effect on acute prostatitis where it reduces oxidative stress and the accompanying inflammation of the prostate gland. In fact, it is believed to have positive effect on many conditions caused by free radical oxidation and excessive reaction by the immune system causing inflammation. Apart from the allergies and arthritis previously referred to, quercetin is believed to have been effectively used in the treatment of gout, macular degeneration and heart disease, and it can also help to prevent the oxidation of low density lipoproteins (LDL) responsible for transporting cholesterol to where it is needed to repair major blood vessels.
When these lipoproteins become oxidized by free radicals then the cholesterol associated with them tends to be excessively deposited in the arteries it is meant to be repairing, and lead to atherosclerosis. This condition can lead to heart failure or to strokes if the blood vessels are in the brain.
Studies have indicated that the flavonoid might help to prevent certain cancers by preventing the nutrition of some types of cancerous cells, effectively killing them. Due to its phytoestrogen properties, quercetin can be used to bind to the sites in cancerous cells that are receptive to estrogen and so prevent their growth. Many types of cancerous cells need estrogen for their growth and proliferation, and phytoestrogens mimic the effect of this hormone. However, these are laboratory studies, and more work is required.
More certain is the effect of quercetin on heart disease due largely to the aforementioned control of cholesterol deposition in your arteries, but also through its ability to strengthen the capillaries. However, when all things are considered, it is in the properties of this non-allergenic bioflavonoid to fight histamine release that it finds it’s most popular and effective use.
So what is the best way to take quercetin? Like most bioflavonoids, it is available naturally in the majority of plant foods. Particularly rich sources are broccoli, red onions, red apple skins, black tea, red wine, red and purple berries and almost all dark green leafy vegetables.
However, the name of the game these days is to take measured doses, and while you should continue to eat these foods, you can also receive controlled doses by use of supplements. From 200 to 500 milligrams thrice daily is a good average dose, depending on the severity of your immune reaction or allergy. Bromelain is believed to improve its absorption in the gut, and quercetin is frequently provided with bromelain, which itself is also a good treatment for allergies and excessive response of your immune system to irritation.
Bromelain is an enzyme, generally extracted from pineapple, and treatments higher than the above doses of quercetin with or without bromelain are available online, although like any natural remedy you should inform your own physician of the dosage you are taking.
There is no better non-allergenic bioflavonoid to fight histamine and its potentially unpleasant effects on your body than quercetin.

Today’s scientists might be less poetic that tea’s ancient admirers. But they are no less impressed by the fragrant beverage’s lengthy list of health-boosting compounds, including a powerful antioxidant called epigallocatechin gallate (EGCG) that may interfere with potentially harmful genetic changes. Researchers at the University of Rochester (New York) Medical Center have found that EGCG binds to a protein called HSP90, jamming an important gene-damaging mechanism (biochemistry 4/5/05). Tea may also help stymie cancer development by interacting with toxin-neutralizing enzymes in the liver and by encouraging apoptosis, a process that causes cells to die when their useful life is over.
Studies of actual tea-drinking humans have had mixed results; some show a cancer-preventive effect, others don’t. The most promising research comes from China, where green tea is the beverage of choice. Among more than 18,000 men, those who drank tea were half as likely to develop cancer of the stomach or esophagus (which leads from the mouth to the stomach) as non-imbibers (Carcinogenesis 9/02).
Americans have traditionally favored black tea, which has different chemical properties. A 2005 American Institute for Cancer Research survey showed that only 15% of the US population drinks green tea on any given day and less than 1% matches the per-person consumption seen in Asia (although green tea sales have climbed considerably in recent years).
Meanwhile, the good news continues to pour in. in February, an investigation published in the Journal Carcinogenesis found a 22% drop in breast cancer risk among women who quaffed five cups a day. And in two preliminary studies, green tea extract, which provides tea compounds in an easy-to-take, form, has been linked to reduced risk of cancer in men with precancerous prostate changes and has benefited people with leukemia.
Green Tea: Supplement vs. Beverage

Green Tea: Supplement vs. Beverage
While most of the studies on Green tea have been done on the consumption of brewed tea, a study published in the American Journal of Clinical Nutrition found that catechin absorption was enhanced when tea polyphenols were administered as a Green tea supplement in pill form.(9) Simply put, the Green tea in supplement form showed enhanced bioavailability compared with that of Green or black tea in beverage form. Whether you prefer to drink tea of take a pill, you are still getting the health benefits of Green tea.
GREEN TEA EXTRACT - For Antioxidant Support
June 29, 2005 01:16 PM
For centuries the art of drinking and serving tea has played a major cultural role in many Asian countries. Americans are now discovering this healthful brew. Studies have shown that green tea is a powerful antioxidant that supports cardiovascular health and promotes dental health and glucose metabolism. The polyphenols are the most beneficial components in green tea, especially the catechin EGCG. Source Naturals offers two convenient ways to get the benefits of green tea: a highly concentrated, 100 mg GREEN TEA EXTRACT or the higher potency 500 mg GREEN TEA EXTRACT. Both extracts are standardized for polyphenols, particularly EGCG.
The Tale of Tea
Green, black and oolong teas are all processed from the young leaves of Camellia sinensis, a white-flowered evergreen that originated in southeastern Asia. Monks brought it to Japan and from there it spread around the world. The three basic types of tea are classified by processing method. black tea is made by fermenting and roasting the leaves, giving it a dark color and rich taste. Oolong is partially fermented. Green tea is lightly steamed so it retains the chlorophyll of the leaf and its green color, along with high concentrations of polyphenol compounds.
The Science of Green Tea
All teas contain polyphenols, which are chemical compounds that act as antioxidants. In green tea the main polyphenols are the catechins, including gallocatechin (GC), epigallocatechin (EGC), epicatechin (EC), and epigallocatechin gallate (EGCG). Studies have shown that these catechins are the beneficial, health-promoting components of green tea, especially EGCG, a proven powerful antioxidant.
Catechins have significant antioxidant power and may prove to be heart healthy agents in combating lipid peroxidation within the cell membranes that line arterial walls. Antioxidants neutralize destructive free radicals and support cardiovascular health by preventing the oxidation of cholesterol. Oxidized cholesterol is an unstable molecule that damages the integrity of arteries. Research shows that EGCG is a much more potent antioxidant than vitamin C or vitamin E. The catechins in green tea have been shown to fight foreign organisms and help prevent the plaque buildup that leads to poor dental health. Research shows that green tea also promotes healthy glucose levels in the blood stream by enhancing the action of insulin.

Nothing to Sneeze At
June 18, 2005 08:41 AM
Nothing to Sneeze At by Carole Poole Energy Times, August 14, 2004
To many, nothing is more annoying than a persistent allergy. Runny nose, itchy eyes, hives, sneezing, coughing...Frequently, allergies seem to represent suffering with no end.
When you are sensitive to something in your environment, often your only hope for relief appears to be to flee to an elsewhere that eludes the problematic, trouble-making allergen.
Complementary measures are available that can lower your risk of allergic reactions. Heading off allergic reactions before they strike can help you enter a comfort zone that leaves nothing to sneeze at.
Limit Your Antibiotics
While people have always suffered allergies, today, many experts agree, allergies are on the rise. One possible explanation: antibiotics. For instance, research at the Henry Ford Hospital in Detroit demonstrates that kids who get antibiotics within six months of being born run an increased risk of being allergic to dust mites, ragweed, grass and animals. At the same time, if two or more cats or dogs live with them, they reduce their chances of allergies (Eur Respir Soc ann conf, 2003).
" I'm not suggesting children shouldn't receive antibiotics. But I believe we need to be more prudent in prescribing them for children at such an early age," Christine Cole Johnson, PhD, says. "In the past, many of them were prescribed unnecessarily, especially for viral infections like colds and the flu when they would have no effect anyway."
Dr. Cole's investigators found that by age 7, kids who got one or more rounds of antibiotics were:
When antibiotics are necessary, they are crucial to quelling bacterial infections. However, if you or your children suffer colds or flus, diseases caused by viruses, antibiotics have no effect on your illness but could increase your chance of developing allergies.
" Over the past four decades there has been an explosive increase in allergy and asthma in westernized countries, which correlates with widespread use of antibiotics and alterations in gastrointestinal (GI) microflora," says Mairi Noverr, a researcher on a study linking allergies to antibiotic use (104th Gen Meet Amer Soc Microbiol, 2004). "We propose that the link between antibiotic use and dysregulated pulmonary immunity is through antibiotic-induced long-term alterations in the bacterial and fungal GI microflora." While a lot of research needs to be done, it may help to fortify the probiotic, or good, microbes in your intestines with probiotic supplements. One study has shown that giving probiotics to pregnant women helped their children avoid allergic eczema, a skin condition (Lancet 2001; 357:1076-9).
Green Tea Relief
Research has demonstrated that various types of tea can produce a range of health benefits. Tea drinkers can add allergy relief to that list.
Research in Japan demonstrates that for the allergy-oppressed, green tea may help them have nothing to sneeze at. In laboratory tests, scientist found that green tea contains a substance that blocks one of the immune cell receptors which is often a part of the allergic response. The substance, methylated epigallocatechin gallate (EGCG), is believed to have a similar effect in the real world (J Agr Food Chem 10/9/02).
" Green tea appears to be a promising source for effective anti-allergenic agents," notes Hirofumi Tachibana, PhD, the study's chief investigator and an associate professor at Kyushu University in Fukuoka. "If you have allergies, you should consider drinking it." Traditionally, many people have consumed tea as part of their effort to suppress sneezes, coughs and itchy eyes caused by allergies. This experiment supports the evidence that green tea, in particular, has a reliable effect.
According to Dr. Tachibana, green tea's anti-allergenic benefits have not been completely established, but tea apparently has the potential to be effective against allergens like dust, chemicals, pet dander and pollen.
EGCG has also been shown to be a very active antioxidant, helping to quell the destructive effects of the caustic molecules known as free radicals. Green tea is richer in EGCG than black tea or oolong tea (a type that falls between black and green).
Although other research has demonstrated that EGCG offsets allergic responses in lab animals fed this substance, scientists don't completely understand why it works for allergies. Researchers theorize that EGCG restricts the production of histamine and immunoglobulin E (IgE), two substances secreted in the body as part of the chain of chemical reactions that lead to an allergic reaction, says Dr. Tachibana.
This study shows, for the first time, that a methylated form of EGCG can block the IgE receptor, which is a key receptor involved in an allergic response. The effect was demonstrated using human basophils, which are blood cells that release histamine. As of now, nobody knows how much green tea you need to guzzle to have the best protection against allergies and, of the several varieties available, nobody knows which green tea is best.
Outside of the US, green tea is the second most popular beverage in the world, right behind water. In the US, however, black tea is more popular than green. But the allergy sensitive should think and drink green.
Stay Away from Diesels
Those who are allergic to ragweed or pet dander usually know they should avoid the source of their allergies. But now scientists have found that, for many allergy sufferers, diesel exhaust can also worsen sneezes and wheezes.
Scientists at two southern California schools have shown that about half of us have inherited a sensitivity to diesel pollution that can make our allergies significantly worse (Lancet 1/10/04). "[T]his study suggests a direct way that pollution could be triggering allergies and asthma in a large number of susceptible individuals...," says Frank D. Gilliland, MD, PhD, the study's lead author. Diesel exhaust particles are thought to act as destructive free radicals in the lungs, forming caustic molecules that damage lung tissue. This irritation can cause your immune system to create larger amounts of compounds that make you sneeze and wheeze more.
The Antioxidant Advantage
Antioxidants, scientists believe, can help defuse this damage and ease the body's allergic responses. The California scientists looked at two antioxidant enzymes the body makes to protect the lungs called glutathione S-transferase M1 (GSTM1) and glutathione S-transferase P1 (GSTP1). Only about five of ten people's immune systems can make all the effective forms of these enzymes. The rest of us lack this protection to some degree, and the immune system in about one in five people can't make any effective form of these enzymes.
The research team found that people allergic to ragweed who lacked these antioxidant enzymes suffered more when they took in both ragweed pollen and particles from diesel pollution.
Breathe Easier With C
This research may help explain why many health practitioners recommend vitamin C, a potent antioxidant, to allergy sufferers. Vitamin C "prevents the secretion of histamine by the white blood cells, increases the detoxification of histamine and lowers the blood-histamine levels," says Sylvia Goldfarb, PhD, author of Allergy Relief (Avery/Penguin).
Scientists continue to study the allergy conundrum. Meanwhile, sip a cup of green tea and shut the window before the next truck comes by.
Botanical Arsenal - Plants can help our bodies fight off cancer's deadly ...
June 13, 2005 10:31 AM
Botanical Arsenal by Fred Thomas Energy Times, May 3, 1999
The complexities surrounding the various types of cancer stem from the variety of ways in which these diseases can wreak their havoc. Luckily, the equally complex world of plants contains novel compounds that can help our bodies fight off cancer's deadly progress.
Research into these botanical compounds is mushrooming. An example: The mighty maitake, a fungus with flair, alternately known as the king (it can grow as large as a basketball, worth its weight in silver to the ancient Japanese); the prince; the Hen of the Woods (it sticks out of from trees when it grows in the wild); and the dancing mushroom to those who leaped for joy when they found one growing in its native northeastern Japan.
Researchers today dub it with a new moniker: Herbal Heavyweight.
Mushroom with Potential
The maitake, with such other medicinal mushrooms as shiitake and reishi, historically has been eaten to promote general well-being and vitality. In the modern lab, however, scientists focus on the potent immune enhancing powers of maitake, which spotlight its cancer fighting potential.
Twenty years ago, maitake, Grifola frondosa, was an obscure, largely unavailable mushroom. A series of significant Japanese studies then catapulted it into prominence-and popularity.
Hiroaki Nanba, PhD, of the department of immunology at Kobe Women's College of Pharmacy on Kobe, Japan, and a leading international researcher on maitake, conducted the preliminary tests on the mushroom, demonstrating that it stimulates immune function and inhibits tumor growth.
In 1986, Dr. Nanba fed powdered maitake to mice injected with tumor cells; 86.3% displayed inhibited tumor growth.
Dr. Nanba and his colleagues went on to run additional mouse tests, finally reporting that this potent mushroom "directly activates various effector cells (macrophages, natural killer cells, killer T-cells, etc.) to attack tumor cells."
From then, maitake mushrooms were headed to fame as cancer ninjas.
Stoking The Immune Engine
Like other mushrooms, maitake is rich in complex polysaccharides, immunomodulators that successive tests after Dr. Nanba's have shown to be effective in cancer and AIDS treatment.
The polysaccharides in maitake have a unique structure, rendering them some of the most powerful to be studied (Chem Pharm Bull 1987:35:1162-8).
What makes maitake a particularly hot property is beta-D-glucan, its primary polysaccharide. Studies show that the body absorbs it readily, at which point it effectively stimulates interleukin-1, natural killer cells and macrophages, anti-tumor warriors that battle solid cancers (Chemotherapy 1990;38:790-6; also International Conference on AIDS, Amsterdam, 1992).
Effective And Safe
In addition to lab tests, trials on people have shown that maitake may offer powerful therapy against liver and stomach cancer (studies in China), breast and colon cancer (US research) and Kaposi's Sarcoma, the virulent cancer attacking AIDS sufferers.
Importantly, studies show that no side effects or interactions accompany maitake's efficacy.
Maitake fortunately has won the interest and enthusiasm of the scientific community. Currently, researchers at the Cancer Treatment Centers of America, headed by Denis Miller, MD, are completing an exhaustive test of the anticancer and immunostimulatory actions of maitake on folks with advanced colorectal cancer. These investigators hypothesize that the polysaccharide beta-glucans derived from the fruitbody of maitake fight tumors and boost immune function. "Though it cannot be said that maitake ...[is] the cancer cure," said Dr. Nanba in his closing remarks at the Adjuvant Nutrition in Cancer Treatment Symposium in Tampa, Florida, in October 1995, "one can safely say that they do maintain the quality of life of patients and improve the immune system, resulting in the possible remission of cancer cells with no side effects."
More Bodily Benefits
Maitake maven Dr. Nanba also has tested-with strongly positive results-the effect of maitake on blood glucose, insulin and triglycerides in mice, whose levels of all three substances declined when they were fed the mushroom (H. Nanba working paper, Anti-Diabetic Activity by Maitake Mushroom, 1994).
With colleagues, Dr. Nanba showed that maitake lowered blood pressure in hypertensive rats (Chem. Phann. Bu//36:1000-1006,1988). Other studies suggest it may accelerate weight loss.
This admirable adaptogen (meaning it helps the body adapt to stress and normalize its functions) is water soluble and may be eaten in food or taken as a supplement. Vitamin C is believed to intensify maitake's beta-glucans and enhance their absorption.
It's not just what you eat that may help protect against cancer, but what you drink as well. Research from China and Japan, where tea is the everyday drink and rates of several cancers like breast and prostate are lower, may persuade you to turn over a new leaf in your own beverage choice. One of the first studies to spark interest in tea came from Shanghai (Journal of the National Cancer Institute, June 1, 1994), where people who drank two to three cups a day were found to have about a 60% reduction in the risk of cancer of the esophagus. The reason: tea leaves contain compounds called polyphenols, potent antioxidants.
In fact, in tests at the University of Kansas, three of these, known as catechins, far outshone the common antioxidant vitamins C and E. Clinical trials are just starting, but early results are encouraging. A team of Chinese scientists reported that in a third of people with precancerous mouth sores who drank three cups of a mixture of green and black tea the lesions shrank significantly.
Researchers at the Saitama Cancer Center in Japan found that green tea seems to improve the prognosis of breast cancer. They followed a group of women with early-stage tumors for seven years. Those who drank more than five cups of green tea a day were only half as likely to suffer a recurrence as patients who consumed fewer than four cups a day.
And at the University of Indiana, toxicologist James Klaunig found that the lungs of cigarette smokers who drank the equivalent of six cups of tea a day suffered 40 to 50 percent less damage from the toxins in smoke, potentially lowering their risk of lung cancer and other pulmonary problems. Simultaneously, research from Purdue University suggests tea's cancer-discouraging powers go beyond being an antioxidant. Scientists Dorothy and D. James Morre showed that a tea catechin dubbed EGCG inhibits a growth-promoting enzyme on the surface of many cancer cells-happily without affecting normal cells. And researchers at the Ohio State University College of Medicine found that EGCG counteracted another enzyme, urokinase, that helps cancer cells spread. To top it off, Mayo Clinic scientists recently showed that EGCG prompted prostate cancer cells to commit suicide (Cancer Letters, Aug. 14, 1998).
So far, most tea research has focused on green tea, and investigators agree it's more potent than the black tea most Americans favor. But because both kinds come from the same plant, Camellia sinensis (it's the processing that makes the difference as black tea is fermented, green tea isn't) both contain cancer-fighting polyphenols, just in different quantities. As long as the tea you drink (even decaffeinated) is fresh brewed, it's likely to provide some benefit; powdered and prepared teas probably don't. And adding milk may dilute the effect.
Astragalus Against Tumors
Astragalus, an herb commonly used in Asia to boost stamina, has impressed western doctors for its potential for helping people cope with chemotherapy. As John Diamon, MD, W. Lee Cowden, MD and Burton Goldberg point out in the Definitive Guide to Cancer (Future Medicine), "Astragalus appears to protect the liver against the harmful toxic effects of chemotherapy and may be effective in treating terminally ill liver cancer patients." (They cite a study in the Jrnl of Ethnopharmacology 1990, 30:145-149.) In addition, they point out, research in Japan supports using a ginseng-astragalus combination to improve the function of natural killer (NK) cells which can boost immunity (Japanese Jrnl of Allergy, 37:2, 1998, 107-114).
Other studies confirm astragalus' potential in fighting off cancer. Research at the General Hospital of PLA, Beijing, showed that flavonoids (pigments) in astragalus could help protect cell membranes from oxidative damage caused by ultraviolet exposure (Chung Kuo Chung Yao Tsa Chih, 21(12):746-8; 1996 Dec).
A study of laboratory animals at Cunma University in Maebashi, Japan, found that Astragalus could help preserve immune function against the harmful side effects of chemotherapy (Chung Kuo Chung Hsi I Chieh Ho Tsa Chih, 15(2):101-3, 1995 Feb).
Like a flame attracting moths, garlic bulbs have irresistibly drawn the attention of medical researchers. A study at Aarhus University, Denmark, found that skin cells in laboratory dishes treated with garlic supplements lived longer, healthier lives than untreated cells (Jrnl Ethnopharm, 1994. 43:125-133).
Meanwhile, a long list of research demonstrates that garlic's phytochemicals may fight tumors and reduce the carcinogenicity of the pollutants and chemicals that assault us daily. A study in China reported in the American Journal of Chinese Medicine showed that garlic helped slow tumors in lab animals (1983, 11:69-73). Another study in the Journal of Nutrition found that compounds in garlic could "suppress the growth of human colon tumor cells" (126, 1355-1361).
Added to those benefits, Robert A. Nagourney, MD, reports in the Journal of Medicinal Food (1:1, 1998, 13-28), garlic may "modify the carcinogenicity of foodstuffs." In other words, studies show that garlic can make chemicals in foods like pork less likely to cause your cells to become cancerous. (Ind J Physiol Pharmacol, 39:347-353).
DNA, the stuff that genes are made of, face constant threats from free radicals, caustic molecules that can alter cellular structure and possibly cause genetic mutations that lead to cancer. But research into what are called oligomeric proanthocyanidins (OPC), flavonoids (pigments) derived from fruits vegetables, grape seed extract and the bark of maritime pine trees shows that OPC may be able to shield DNA from injury.
In particular, studies of a grape seed extract called Activin have demonstrated this substance can help liver cell DNA escape a destructive process called peroxidation (FASEB, 11:3, 2/28/97).
In these experiments, Activin demonstrated the ability to inhibit the growth of tumor cells as well as slow the replication enzymes of HIV viruses. This protective ability proved to be more potent than that of vitamin C, beta carotene and vitamin E.
What does the future promise to reveal? Scientists believe that many unexamined plants probably contain undiscovered phytochemicals that hold great potential for helping us fight the cancer epidemic.
Certainly, if the next few years produce as many results as the past decade, the next millennium will witness a long line of cancer-prevention discoveries. Before long, you should be able to take advantage of these potent substances.
As you gulp your garlic, tip your tea cup, mull your maitake, acquire Activin and await your astragalus, you may meditate on what may soon be added to our growing anti-cancer arsenal. Undoubtedly, scientists with a botanical bent will be uncovering more coveted anti-cancer secrets before too long.
Vitali-Tea - Tea fits a healthy lifestyle to a T...
June 13, 2005 09:45 AM
Vitali-Tea by Leah Brinks Energy Times, October 9, 2003
If the research is even only half right, tea fits a healthy lifestyle to a T. Whenever scientists look at a teapot's contents, they find striking health benefits: Heart protection. Reduced cancer risk. Better skin.
All of these are apparently in the bag when you choose to drink tea. Tea green, tea black: Which to choose? Actually, both types come from the same plant, Camellia sinensis. Green tea is steamed and dried; black tea is fermented, which allows its darker color to develop. Some lesser-known types include white tea, which is actually green tea that undergoes the most minimal of handling. (Another rare white tea, white cantaloupe, is rich in antioxidants.) Oolong is a tea that falls between green and black in processing and flavor.
One increasingly popular tea color, red, is not tea at all, but an herbal brew called rooibos (technically, herbal teas are known as tisanes). This South African plant yields a citrus-flavored beverage high in vitamin C. Other herbs known for yielding flavorful infusions include chamomile, used to promote sound sleep; peppermint, a digestion easer; and rose hips, which, like rooibos, combines healthy vitamin C levels with a delightfully zesty taste.
The evidence for tea's health benefits has practically boiled over. For instance, researchers at the University of Rochester have found that green tea substances inhibit the action of a molecule irritated by tobacco smoke, a toxin central to tobacco's cancer-causing danger. This action, say the scientists, may be the reasons that smokers who drink tea suffer less cancer (Chem Res Tox 7/21/03).
The Rochester researchers found that tea helps protect a cellular molecule called the aryl hydrocarbon (AH) receptor. Ordinarily, AH is frequently disturbed by toxic substances that cause cancer and other illnesses. Tobacco smoke (as well as the pollutant dioxin) interacts with AH to initiate cancer and other problems.
But at least two chemicals in green tea-epigallocatechingallate (EGCG) and epigallocatechin (EGC)-interfere with AH's harmful activity. These substances, flavonoids similar to healthful chemicals found in grapes, wine and cruciferous vegetables like broccoli, have been shown to lower cancer risk.
"It's likely that the compounds in green tea act through many different pathways," says Thomas Gasiewicz, professor and chair of Environmental Medicine and director of Rochester's Environmental Health Science Center.
In the Rochester study, Dr. Gasiewicz and his colleagues found that EGCG and EGC close down the AH receptor in cancerous animal cells and most likely produce the same benefit in human cells.
Still to be made clear is how tea is metabolized when the body digests tea, but the Rochester scientists are still peering through their microscopes and teapots to find out.
Scientists at the Linus Pauling Institute at Oregon State University have found that drinking green or white tea can significantly lower your risk of colon cancer as well the prescription drug sulindac, which has been shown effective for people at high tumor risk (Carcinogenesis 3/03).
"Tea is one of the most widely consumed beverages in the world, and recent upswings in the sales of green tea in the United States can be attributed to reports of potential health benefits against cancer and other chronic diseases," says Gayle Orner, an OSU research associate. "Teas exert significant protective effects in experimental animal models of skin, lung, esophageal, gastric, hepatic, small intestinal, pancreatic, colon, bladder and mammary cancer."
While many people today take aspirin and similar drugs that have been shown to lower cancer risk, this study shows that drinking tea and taking low doses of these drugs, called NSAIDs, can reduce the risk even further. (High doses of NSAIDs, while protective against colon cancer, can cause internal bleeding.)
"These are pretty exciting results," Orner says. "What's especially significant is that as far as we can tell consumption of tea has none of the side effects of NSAIDs, which can be severe, including bleeding, ulcers and even death."
In this research on animals, use of tea dropped the risk of cancer by about two-thirds. According to the lab results, drinking about three large cups of tea a day should provide significant cancer protection. Based on research in Japan that looked at how green tea lowers the risk of stomach cancer, the Linus Pauling scientists urge plenty of tea drinking: "The more the better."
Studies show that nations of tea drinkers have less trouble with their hearts than residents of places where tea is hardly ever brewed. And now research is starting to zero in on the substances in tea that benefit heart health.
A study of 240 Chinese men and women who have high cholesterol has found that chemicals in tea can significantly drop harmful cholesterol (Arch Int Med 6/23/03).
"Personally, I was very surprised," says David J. Maron, MD, professor at the Vanderbilt University Medical Center, lead author of the study. "I expected, if anything, a very slight cholesterol-lowering effect. But what we saw was a 16% reduction in low density lipoprotein (LDL) cholesterol."
LDL cholesterol is known as "bad" cholesterol because it can increase your risk of heart disease.
The researchers in this study gave people extracts of green and black tea enhanced with theaflavin, an antioxidant also found in green tea.
In the future, if past results are any indication, tea's rich supply of beneficial chemicals will continue to pleasantly surprise researchers with even more benefits.
White Tea 500mg 60 Vegi Caps.
May 07, 2005 09:46 AM
Newly released by Solaray White Tea 500mg per capsule, White Tea is a rare chinese tea made from the youngest and most tender buds. The buds are carefully picked in the spring while still covered in fine silvery white hairs.
Unlike the other varieties of Camellia sinensis: Green, Oolong and black tea; White tea is not withered or fermented.
