Overcoming adrenal fatigue naturally
July 22, 2018 11:53 AM
The human body has a well-developed system it uses to aid us when we experience stress. Firstly, the brain identifies the threat. Then the body releases hormones designed to do two things, rush blood to the muscles and heart to assist in fighting off the aggressive agent and dampening body processes that are not needed in the attack, such as digestive ones.
Were one fighting of a saber-tooth tiger, this would be of benefit. Today's stresses are far more nuanced, insidious and long-lasting. And when constant stress overworks the adrenals, which are the rabble-rousers in charge of turning off immunity and digestion until the tiger has turned tail, well then they get tired. This condition is called, aptly, adrenal fatigue. It can last for a short while, or a long time. It induces fatigue and it can lead to "brain fog." Other symptoms can include disturbances in mood, or sleep, food cravings and muscle and bone loss. To recuperate, it's necessary to convince the body the tiger has gone. Eat healthy, sleep healthy. Take vitamins and nourish yourself physically and psychically.
"One of the most important parts of restoring adrenal function is listening to your body and minding your stress levels."

Some researchers believe that Overcoming stress and depression may be as easy as breathing. Many studies have been done to test the effect of slow and steady breathing on the body. Scientists have found that people who practice breathing meditation on a regular basis are able to lower their stress hormones and cytokines that have an adverse effect on the body. So, the next time you feel stressed, just practice some deep breathing to help calm yourself.
"Controlled breathing, like what you just practiced, has been shown to reduce stress, increase alertness and boost your immune system."
Importace of vitamin k-2
June 06, 2014 04:08 AM
We all know that calcium is needed for healthy bones and teeth. If calcium deficiency in the body is neglected for many years, it may cause bone disease in old age, which is also known as osteoporosis in medical terms, and many other complications. Vitamin K-2 works to help with the absorption of the calcium ions in the body.
Calcium supplements or tablets are normally recommended by doctors all over the world to overcome calcium deficiency. There are tablets that one can use to replenish the calcium in their body. Therefore, calcium supplements and one's bone health are closely related to each other. By taking vitamin K-2, there will be no need of taking the supplements.
Where can you find calcium
Calcium is mostly found in our bones, teeth, blood and cells. Almost 98% of calcium present in the body is concentrated in the bones where it is needed for the right development of the skeletal system. It has also a lot of vitamin K 2 which will help in absorption of the calcium important in the formation of bones.
Calcium supplements and one's bone health are connected by the very fact that they will not only help in Overcoming calcium deficiency in the body, they will also help in preventing many degenerative diseases that are related to the skeletal system for instance osteoporosis.
Our immune system is the one that is responsible for maintaining the health of our bones. However, as we age our immune systems becomes weak and do not perform at its maximum due to other health conditions. At this age, doctors nowadays advocating for nutritional supplements for bone health and health specialists. Liquid calcium supplements together with the tablet forms offer many benefits in respect to the overall well being of your body. The vitamin K-2 will help in keeping the immune system strong, giving us strong bones.
Relax With Passion Flower, and Overcome Your Insomnia
June 09, 2011 11:33 AM
Passion flower is used by many people to help them relax and overcome their insomnia. People who find it difficult to sleep have discovered that a few drops of passion flower extract or a passion flower tea before bed can help them relax and get to sleep. They are amongst a growing number of people trying to avoid diazepam and Valium as a means of relaxation and Overcoming stress, because it doesn’t get them hooked.
According to a study carried out by some PhD researchers and reported in the Journal of Clinical Pharmacy and Therapeutics in 2001, the alkaloids and flavones contained in passion flower are just as good as these oxazepams at calming your general anxiety levels, yet do not impair your ability to work as the likes of diazepams such as Valium do, and are also non-addictive.
Passion flower works by calming you down through its effect on the neurotransmitters in your central nervous system, and not only overcomes general anxiety symptoms, but helps you to relax and sleep well at night. It is a natural substance, unlike the synthetic chemical nature of diazepam and other oxazepams and many insomniacs find it a godsend.
BoneSet For Fevers
June 09, 2009 12:15 PM
Boneset was used by Native Americans for a valuable remedy against colds, flu, and fevers. Other common names that boneset is identified by include: thoroughwort, vegetable antimony, feverwort, agueweed, Indian sage, sweating plant, eupatorium, crossword, thoroughstem, thoroughwax, and wild Isaac. In most cases, boneset has been used primarily to treat fevers. They introduced boneset to the settlers in the New World. From 1820 through 1916, boneset was listed in the U.S. Pharmacopoeia. This herb was also listed in the National Formulary from 1926 through 1950. Boneset has been used to restore strength in the stomach and spleen. It has also been used as a tonic for acute and chronic fevers. Dr. Edward E. Shook actually felt that boneset was beneficial for every kind of fever humans are subjected to. He also believed that it had never failed in Overcoming influenza.
Recent research has found that boneset contains antiseptic properties that help to promote sweating. These properties also help in cases of colds and flu. Boneset has also been shown to contain antiviral properties and strengthen the immune system by enhancing the secretion of interferon. Additional studies have found that boneset is effective against minor viral and bacterial infections by stimulating white blood cells. Additionally, this herb has been used to treat indigestion and pain and may also contain some mild anti-inflammatory agents to help with conditions like arthritis.
Boneset is a perennial herb that has an erect stout and a hairy stem. It grows from two to four feet high, with branches at the top. The leaves of the boneset plant are large, opposite, united at the base, and lance-shaped. They grow anywhere between four to eight inches in length and taper into a sharp point. The edges of these leaves are finely toothed, with prominent veins. These leaves help to distinguish this plant species at first glance. The flower heads of the boneset plant are terminal and numerous, being large, and having anywhere from ten to twenty white florets. The plant possesses an aromatic odor, with an astringent and strongly bitter taste. This plant species varies considerably in size, hairiness, form of leaves, and inflorescence. It can typically be found flowering from July to September.
The entire herb is used to provide alterative, anti-inflamamtory, antiperiodic, antiviral, diaphoretic, emetic, febrifuge, purgative, nervine, and stimulant properties. The primary nutrients found in boneset include calcium, magnesium, PABA, potassium, and vitamins C and B-complex. Primarily, boneset has been shown to be extremely helpful in dealing with chills, colds, coughs, fever, flu, malaria, pain, rheumatism, typhoid fever, and yellow fever. Additionally, this herb is beneficial in treating bronchitis, catarrh, jaundice, liver disorders, measles, mumps, Rocky Mountain spotted fever, scarlet fever, sore throat, and worms. For more information on the many beneficial effects provided by boneset, please contact a representative from your local health food store.
Although there is no recent clinical evidence that guides the dosage of boneset, traditional use of the herb suggests that a dose be about two grams of leaves and flowers. The internal use of this herb should be tempered by the occurrence of hepatotoxic pyrrolizidine alkaloids in this plant. For those women who are pregnant or lactating, this herb should not be used, as there have been documented adverse effects on those women who are pregnant and/or lactating.
Boneset is available in capsule, tablet, and liquid extract forms at your local or internet health food store. Look for name brands to ensure quality and purity of the product you purchase.
EFA's - Essential Fatty Acids
September 15, 2008 09:42 AM
Many recent studies have found that EFAs may be extremely helpful for many chronic, stubborn conditions. Their continuously growing range of applications includes Overcoming diseases such as alcoholism, breast cancer, and cardiovascular disease; strengthening the immune system; helping eliminate yeast infection; reducing symptoms of premenstrual syndrome; minimizing inflammation of rheumatoid arthritis; and assisting in the proper management of weight.
Alcohol dependence is an extremely serious condition that often results in decreased life expectancy, suicide, degeneration of the brain and liver, osteoporosis, and many other conditions. For each person, the rate at which alcohol is metabolized in the body is different, as a lot of it has to do with the person's nutritional status, the concentration and activity of liver enzymes, and the rate at which alcohol is consumed.
Alcoholics tend not to eat because the calories from alcohol, although nutrient-poor, diminish the appetite, causing many alcoholics to become extremely malnourished. An overall nutritional program should be employed to those people who are dependant on alcohol, which should include vitamins A, C, and B, complex, along with zinc, magnesium, selenium, amino acids, milk thistle, acidophilus, antioxidants, L-carnitine, and essential fatty acids. EFAs, especially those that are high in GLA, keep blood lipid levels from going out of control.
The body's immune system has a vital role in protecting us against cancer, as it recognizes and annihilates any abnormal cells before they have the chance to multiply and do damage. When the immune system is overwhelmed or not functioning properly, abnormal cells will reproduce without having anything to stop them. Because of the rapidly growing tumors which have a huge appetite for nutrition to keep them going, cancer patients often become malnourished and lose weight. A diet that is rich in cruciferous vegetables, fiber, antioxidants, vitamins A, C, and E, minerals, and essential fatty acids can help prevent breast cancer. Research shows that EFAs, especially GLA, have anti-tumor properties.
All of the cells in the body have a dependence on nutrients that are transported through the circulatory network. When blood vessels become clogged with fats and cholesterol, nutrition distribution is hindered and blood flow can be stopped in some areas, causing the heart to die. Exercise is a good for increasing circulation and keeping the blood from getting stuck. A diet that is high fruits, vegetables, natural fiber, and low in saturated fats, meats, and homogenized dairy products is also a good idea. Additionally, antioxidants, hawthorn berry, ginkgo biloba, vitamin E, Co Q-10, L-carnitine, calcium, magnesium, potassium, and EFAs will also be of benefit to the cardiovascular system.
Essential fatty acids have been shown to stop the growth of yeast organisms in the body. They do so by helping the oxygen to flow to cells. Since yeast is anaerobic, it cannot thrive in the presence of oxygen. Yeast overgrowth can cause a variety of symptoms that are often diagnosed as another condition, ranging from joint swelling to memory loss.
PMS is a collection of symptoms that occurs one to two weeks before menstruation, affects about one-third of women who are younger than forty. It is caused by hormone imbalances, which result in anxiety, irritability, and mental sluggishness. Research has found that women with PMS usually eat more refined carbohydrates, dairy products, and sodium, and less iron and other minerals than those women who do not experience this condition. Vitamin B complex, beta carotene, vitamin E, magnesium, milk thistle, acidophilus, and essential fatty acids are very helpful for PMS. Essential fatty acids, especially GLA, are helpful in balancing the body's hormone levels.
Reducing symptoms of disease like arthritis or PMS is important to all those who suffer from them. EFA's can help reduce the symptoms of these diseases. American diets are low in EFA's and one should consume them either in the foods they eat or supplement form to help the body strengthen its self and fight off disease.
Evening Primrose Oil
September 04, 2008 09:08 AM
The tiny seeds of the evening primrose flower are the source of oil that has been valued in the world for building health and Overcoming a lot of common health problems. Evening primrose, also known as evening star, night willow herb, scabish, and tree primrose, has a recorded history of at least 500 years of use for its health promoting properties. Growing in a wider variety of climates, the plant can be found in rocky roadsides, shallow streams, or even high deserts.
The plant can even be found growing at elevations as high as 9,000 feet. This plant has yellow flowers from July through September that open after sunset and are pollinated by insects of the night. Open only until sunrise, the flowers die the next day, causing hundreds of small black seeds to form inside. These seeds are the source of the plant’s oil, with about 5,000 seeds being used for just one 500 mg capsule. Due to this, evening primrose can be relatively expensive. Evening primrose’s value in a variety of illnesses was recognized by American Indians and European immigrants. Indians used it to treat skin wounds, asthma, coughs, and also as a sedative. One of the first botanicals exported to Europe from North America, it was brought to Italy in 1619 and planted in the Padua Botanical Gardens. It was so valued by the Puritans that they called it the “King’s cure-all” and exported it to England. The ancients didn’t know scientifically why evening primrose was so effective for so many illnesses, but that didn’t affect its abilities. Modern science has found that the essential fatty acids that are found in the oil of the evening primrose seeds are the secret to the health-building properties.
Fat has gotten a bad name for itself in the past few years, but the truth is that there are actually certain types of fats that are vital for good health. One of these healthy fats is essential fatty acids, which are found in unprocessed vegetable, plant, and fish oils. One of the richest sources known is actually mother’s milk. Like vitamins and minerals, essential fatty acids are nutritional substances that have far-reaching effects on many body processes.
These effects include reducing blood pressure, helping to prevent arthritis, reducing the growth rate of breast cancer, lowering cholesterol and triglyceride levels, maintaining healthy skin, aiding in transmission of nerve impulses, playing a role in normal brain function, constituting the building blocks of body membranes, promoting proper hormone function, and forming the basis for prostaglandin production.
Because essential fatty acids can not be manufactured in the body, they must be consumed in the diet, with at least three percent of an adult’s daily caloric intake being recommended to be comprised of essential fatty acids. Children and pregnant women should have a diet containing at least five percent essential fatty acids. Essential fatty acids are essential for normal functioning of all body tissues.
Because of this, the list of symptoms of essential fatty acid deficiency includes reduced growth rate, skin disorders, male and female infertility, kidney abnormalities, decreased capillary resistance, susceptibility to infection, heart problems, anemia, enlarged liver, sparse hair growth in infants, poor wound healing, and an increased susceptibility to infection.
In conclusion, to prevent or heal these conditions, a diet that is rich in essential fatty acids must be present. Evening primrose oil is a good source of essential fatty acids, containing about 72 percent linoleic acid and 9 percent GLA. Have you had your evening primrose oil today?
Give Your Health A Boost With Beta Glucan
February 19, 2008 04:54 PM
Beta Glucan is a little-known component of many common foods we eat on a daily basis. Cereal, mushrooms, and even baker's yeast contain beta glucan. The substance is most common found in such grains as barely and oats. Beta glucan is often used in soluble fiber supplements. The FDA has given baker's yeast the rating for being generally safe (G.R.A.S.).
Beta Glucan has been studied in Japan for its anti-tumor and anti-malignancy properties. It is commonly known worldwide to have a significant impact on improving the human immune system. The clinical applications have been many for this substance. Beta glucan has been studied for preventing infection in post-operative patients. Likewise, it has been attributed with slightly faster, more efficient healing of wounds. Beta glucan has helped patients with septic shock.
This substance has also been studied for its effects on individuals suffering from arthritis. Beta glucan has been attributed with slowing the disease's progress and preventing further damage to tissues. Beta glucan has been studied for decades, however was too expensive for the general public until recent times. It has no known reactions with prescription medications and beta glucan supplements derived from baker's yeast isn't know to contain enough to cause a reaction in those with yeast allergies.
There are also on-going studies regarding beta glucan and it's usefulness with radiation and radiation exposure. There is a great deal of interest that this can perhaps lessen the severity of symptoms from radiation in chemotherapy and help those experiencing nuclear therapy or who are involved in a nuclear emergency.
Beta glucan is one of the few nutrients that are recommended for both humans and animals. It is also advised for those who have poor daily nutrition, athletes, those regularly exposed to radiation, individuals under stress, or anyone who wants to stay healthy. In truth, studies indicate that consumption of oats, cereal grains, and other beta glucan containing products can lower cholesterol, can aid in Overcoming intestinal problems, and can benefit those diagnosed with AIDS and multiple sclerosis.
Beta glucan strengthens the cells responsible for fighting foreign invaders in the body such as viruses, bacteria and even parasites. It helps these cells be more responsive and stronger when free radials enter the body. One study in Canada evaluated the response of beta glucan to Anthrax. As a result, the beta glucan proved to be a very effective supplement to the antibiotics used in treating this disease.
Higher dosages do not equal effectiveness. Beta glucan is not measured by the size or milligram of the supplement. The determining factors for the effectiveness of beta glucan involve how the substance is processed and if the particular pill re-aggregates during the digestive process. If your supplement re-aggregates, it will not have the same effective nature as those that do not.
Be sure to evaluate the labels and inspect the image the company is portraying. If a product is "too good to be true," it is. As always, consult with your physician before starting this or any other long-term supplement.
Take Charge Of Your Health With Herbal Bio-Identical hormones
November 04, 2007 03:17 PM
Bioidentical hormones assist women in Overcoming acute menopausal symptoms, while improving skin. They help by strengthening bones, keeping the mind sharp, promoting energy and well-being, and helping to preserve vaginal tone and resist vaginal dryness. In men, these hormones add energy and vitality, while improving muscle tones and mental sharpness. Bioidentical hormones (BHRT) are exact duplicates of the hormones that are produced by the body. However, they are much more easily metabolized by the body into safe forms of estrogen than their counterparts, which stimulate toxic metabolites. When they are used in physiologic amounts, bioidenticals carry much fewer risks than synthetic hormones. However, despite the fact that research supports their use and proves them safe alternatives to prescription drugs, few physicians are actually using these hormones in their practices.
Those patients, who wish to address menopausal and andropause symptoms, or to achieve lifelong hormonal balance in order to prevent illness, often do not know where to go to find a comprehensive bioidentical hormone replacement program. Instead, they read whatever they can to formulate a plan and purchase various products that are available over the counter, often spending precious time and money on programs and products that don’t do what they’re expected to do. One of the most common errors among people is putting together a program based solely on symptoms instead of first checking hormone levels. Symptoms may overlap from one hormone pattern to another. If you try to replace or augment specific hormones without having an accurate test of the levels first, your results will seldom be good.
If your doctor is prescribing transdermal hormones, make sure to do a saliva self-test to measure your hormones levels as it is much more accurate and revealing than other types of tests. You can submit your samples to Mead Labs, where you will actually receive a telephone consultation from a health professional to interpret your results followed by a program of products prescribed especially for you from one of their medical professionals. With your own results, you can learn a lot about the exact state of your hormones instead of blindly guessing from symptoms which may be similar. For example, men may not need testosterone shots or transdermal patches, as the results may show estrogen dominance. The answer for this is not adding more testosterone, because the man could be converting testosterone into estrogen, but instead a program including special herbs and nutrients may be much more beneficial. No matter your gender, your health professional at Mead Labs will design a safe and effective program based solely on bioidentical hormones, herbs, and nutrients first. In the past years, when prescription, non-bioidentical HRT was used by any women with menopausal symptoms, there was no testing to find out what kind of imbalance was actually occurring. Proponents of BHRT are trying to ensure that this method of prescribing the same combination and amounts of medications to everyone is not used with natural hormones. Because hormone profiles and levels can vary significantly from person to person, even those people in the same gender, testing hormones levels and obtaining recommendations from a medical professional who is experienced in BHRT are the key points to ensure you benefit from this therapy.
Medical Tourism Adopted by Businesses
September 19, 2006 05:46 PM
(NewsTarget) A number of U.S. employers that fund their own health insurance plans have started sending their employees to countries such as India and Thailand for operations that can cost tens of thousands of dollars more in the United States.
“the hospitals have a monopoly,” says North Carolina based Blue Ridge Paper Products Inc. benefits director Bonnie Blackley. “They don’t care, because where else are patients going to go? Well, we’re going to go to India.”
“This accelerating trend of medical tourism,” adds Mike Adams, a medical industry watchdog and critic to conventional medicine, “is the free markets way of Overcoming the anti-competitive, monopoly practices that have now become accepted as standard in the U.S. medical industry. Despite the industry’s best efforts to exploit patients by limiting their options, smart consumers are realizing that U.S. meical costs are, indeed, a sham, and that they can get the same level of care – plus a free vacation to Asia – for a fraction of what they’d spend in the U.S.”
The benefits of a manual exam for prostate cancer far outweigh any embarrassment.

2. The benefits of a manual exam for prostate cancer far outweigh any embarrassment.
While women routinely visit the GYN for yearly or even bi-yearly exams, many men find the idea of being examined so intimately to be disconcerting. “It’s not their favorite exam, but it’s not that painful,” admits Dr. E. Roy Berger, MD, FACP, Director of North Shore Prostate Cancer Consultation and Treatment Service at North Shore Hematology/Oncology Associates in East Setauket, New York. “There is no spectrum involved. It’s just a finger.” Education and understanding are the key to men Overcoming their anxiety. It’s also an opportunity for women to reassure their significant others that this type of exam is vital to good health and a gratifying love life. “Patients should actually ask their primary care doctor for a digital rectal exam,” suggests Berger. “It’s a matter of mindset.”

One of the reasons St. John’s wort is attracting so much interest is because of one of its compounds, hypericin. The journal Photochemistry-Photobiology recently published a review of hypericins and the structurally related hypocrellins, giving a favorable outline of the various recent breakthroughs in medicine using these two compounds. The review states, Hypocrellins and hypericins, structurally related plant pigments isolated from Hypocrella bambuase and Hypericum respectively, are known photodynamic agents. This review summarizes certain significant advances in the phtotophysics, photochemistry and photobiology of these pigments in the last two years and discusses their prospects as novel therapeutic and diagnostic agents in the future . . . In particular, substantial progress has been made in both anticancer and antiviral applications (especially anti-human immunodeficiency virus). . . . The biomedical advances of hypocrellins and hypericins have been further promoted by significant progress in their chemical synthesis and the recent commercialization of . . . hypericins.2 The compound hypericin was isolated from St. John’s wort in 1942 and has been used as an anti-depressant and mood stabilizer for emotionally and mentally disturbed people.
Among its many beneficial qualities is that of increasing blood flow to stressed tissue, thereby having a tranquilizing effect. It also reduces the fragility of capillaries and enhances uterine muscle tone because of its ability to increase blood flow.3 It is this compound that is being extensively researched for its possible therapeutic properties for a variety of diseases, mainly depression, AIDS and other viruses, cancer and sleep disorders.
Extensive research has been done, especially recently, to determine exactly how hypericin works in treating these and other disorders. Nearly all the researchers are saying the same thing—that Hypericum (and specifically hypericin) promises significant value to the medical world in Overcoming these serious disorders. The following sections discuss the various disorders that are being researched in conjunction with Hypericum/ hypericin therapy.
Important Information for Allergy Sufferers
May 13, 2005 09:52 AM
Important Information for Allergy SufferersRichard Conant, L.Ac. C.N.
Imagine you are one among millions who greet each spring with worry about the flood of pollen that fills the air this time of year. When the pollen season arrives, as it inevitably does, you find yourself with two choices. You can either take over-the-counter antihistamines and put up with unpleasant side-effects, or endure the sneezing, runny nose, itchy, watery eyes and other discomforts of hay fever.
If there was a natural ingredient, a nutritional substance found throughout nature in many foods and plants, that could offer an alternative, would you not be interested?
Quercetin, one among hundreds of flavonoids found throughout the plant kingdom, is this ingredient. Quercetin has been researched in numerous pharmacological studies. The results of this work strongly suggest that quercetin helps to stabilize the fundamental process in the body which causes an allergic reaction. Quercetin, as shown in test-tube ("in vitro") studies, prevents the release of histamine from "mast cells," immune cells that stand guard in the tissues which meet the outside environment—the nasal passages, the lungs, the digestive tract and skin. While this has yet to be confirmed by human clinical trials, in the picture that emerges from the research so far, quercetin looks like a rescue nutrient for allergy sufferers.
Reports from Quercetin Users
I have seen numerous reports from individuals who have indeed achieved significant reductions in allergic sensitivity by using quercetin. And this includes food allergies as well as environmental allergies. Anecdotal stories like these carry little weight among scientists, because they do not provide evidence that the observed result will be repeated in other cases. Only placebo-controlled, double-blind studies can produce this kind of scientific proof. Yet, when anectodal evidence (this includes physician "case reports") correlates with the results of pharmacological research such as we have on quercetin, I believe it should be taken seriously. And quercetin is a nutrient that works effectively when taken as a dietary supplement.
For example, one gentleman writes that his wife, who is allergic to pollen and dust, is now "sneeze-free" after using quercetin for three years. A Pennsylvania woman writes that her husband, also a long time allergy sufferer, "seems to be nearly allergy free" after one month of use. Another man says that "quercetin has literally changed my life." These are not isolated cases; a respected nutritionist who specializes in allergies and environmental problems has seen many similar outcomes with a quercetin. Clearly something significant is going on with respect to quercetin as a nutritional approach for Overcoming allergies.
Bear in mind, though, that quercetin does not function like an antihistamine medication; it is not a quick fix. As a nutrient that helps to normalize body functions naturally, quercetin needs time to work, and should be taken for at least two or three weeks to achieve these results.
Exerting a broad range of biological effects, quercetin is perhaps the most active and versatile flavonoid. In test-tube studies, quercetin acts directly on the mast cell in a way that quiets the allergic response.
An allergic reaction occurs when IgE antibodies, positioned on the mast cell surface, come in contact with a potential allergy-causing substance like pollen. The mast cell is then signaled to release histamine from storage granules located inside the cell, through a process called "degranulation." The histamine circulates throughout the body, causing the runny nose, itching and other discomforts associated with allergies.
Quercetin stabilizes mast cell membranes, in effect turning down the allergic response signal. Quercetin also slows other mechanisms which are involved with inflammation, such as the production of inflammatory prostaglandins and leukotrienes. This adds to its membrane-stabilizing effect, and its value in allergy control.
Quercetin appears to substantially raise the threshold for initiation of an allergic reaction. In allergy sufferers this threshold is low, for reasons which are not well understood. They may have more IgE antibodies than normal, making the mast cells overly "trigger happy." Histamine has its proper place in the immune response that defends us against truly harmful foreign substances in the body. But like many chemicals produced by the body, histamine is a two-edged sword. In allergy-prone individuals, the mast cells have become overreactive, releasing too much histamine, unnecessarily. With quercetin in the bloodstream, histamine release from mast cells is kept under control. Quercetin's ability to down-regulate both the inflammatory and allergic responses makes it, I believe, a highly important nutrient for humans to consume on a regular basis.
Quercetin-the Scientific Evidence
Several studies, published in respected journals such as the Journal of Allergy and Clinical Immunology and others, have demonstrated quercetin's ability to control the release of histamine from mast cells. (Quercetin has the same effect on basophils, a type of white blood cell that also contains histamine.) In these experiments, mast cells taken from both animals and humans are exposed in the test tube to various substances—called "antigens"— that stimulate histamine release. The researchers then add an inhibiting agent such as quercetin to the mixture and measure the differences in histamine output. Quercetin has shown itself to be one of the more powerful histamine inhibitors, more powerful, in fact, than disodium cromoglycate, an anti-asthma drug.
Quercetin has other beneficial properties. A strong antioxidant, Quercetin has a higher level of antioxidant activity than both vitamin C and vitamin E. (Quercetin enhances the antioxidant activity of vitamin C; quercetin and vitamin C are true synergists.) Quercetin has been shown to block the oxidation of LDL cholesterol by free radicals. Quercetin also protects cell membranes from being injured by oxidized LDL. The damage that oxidized LDL causes to the delicate membranes of blood vessel linings allows plaque deposits to form, setting the stage for atheroslcerosis. These observations point to quercetin as a key nutrient for maintaining cardiovascular health.
Like all flavonoids, quercetin is not classified as an essential nutrient, although flavonoids were once called "Vitamin P." In view of its many beneficial actions, quercetin is a nutrient that clearly has important roles to play in human nutrition, for allergy sufferers, and for everyone.
