Quercetin is a bioflavonoid (sometimes called vitamin P) that is packed with natural antioxidant, antiviral, anti-inflammatory and antiallergenic qualities. Normally found in highly nutritious foods and plants, such as citrus, red apples, teas, broccoli and onions, etc., you can easily take it in a supplement form; and because the human body cannot produce bioflavonoids, they must be supplied in the diet - and you should supply them to maximize sound health!
Quercetin is a bioflavonoid, an important member of a large group of compounds that are found in many herbs and plants, including Onions (thought to have the largest amount), Broccoli, Citrus fruits (especially the white material just beneath the peel of citrus fruits), Grapes, teas (especially Green Tea), Blue-green Algae, Red Apples, Red Wine and many others.
Although not a real vitamin in the true sense, it is sometimes referred to as vitamin P, a so-called vitamin that maintains the resistance of cell and capillary walls to permeation. Bioflavonoids cannot be manufactured in the body and are necessary for good health and essential for the absorption of vitamin C. It is recommended that Quercetin and vitamin C be taken simultaneously for optimum efficacy. Bromelein, too, is said to help absorption of Quercetin; they're synergistic, and taking them at the same time will enhance the efficacy of Quercetin.
There are many different bioflavonoids, including Quercetin, RUTIN, Hesperidin, flavones, citrin, etc., and some of the herbs that contain this essential nutrient include Chervil, Elderberry, Hawthorne, Horsetail, ROSE HIPS and Shepherd's Purse, to name a few. Recent studies show that bioflavonoids may be a big factor in preventing invasive infection and serious malignant diseases.
Pursuant to fighting malignancy, Quercetin is said to stop the chemical signals that give ovarian Cancer cells a growth advantage over healthy cells. Furthermore, studies at the Indiana University School of Medicine have found that Quercetin and genistein (a key isoflavone in SOY) will enhance each other's effects when combating ovarian and other malignant cells and may thus be more effective when used together.
Quercetin is considered an anti-allergenic and is said to inhibit allergic reactions by preventing multiplication of cells that secrete histamine, the chemical that causes inflammation and swelling; and it does not induce drowsiness often accompanying the use of antihistamines because its action does not act upon the nerves that stimulate the cells. Quercetin is said to help the lungs deal with dust and particle pollution and can benefit the discomforts of emphysema, asthma, bronchial problems, Hives and other allergies.
With regard to cataracts, diabetic retinopathy and Macular degeneration, although Quercetin does not correct the blood-vessel defects that cause these disorders; it does protect the cells of the retina and the eye's lens from the effects of low oxygen levels and neurological toxins.
Quercetin is thought to help blood vessels injured by debility or high Blood pressure by inhibiting the growth of Cholesterol that forms into plaque in the blood vessels. It is said to slow the chemical reactions that cause large numbers of macrophages to cluster on the artery walls, reducing plaque formation (clotting), which can be beneficial for promoting improved blood Circulation and reducing the risk of arteriosclerosis.
Chemically similar to sodium cromoglycate, a drug that is used to protect against migraines provoked by foods known to cause a Migraine attack, Quercetin inhibits many of the pathways of inflammation associated with Migraine and is said to prevent headaches associated with allergies.
Quercetin may help to prevent heart problems by reducing the oxidation of LDLs (bad Cholesterol) in the blood and promoting normal Blood pressure levels.
Considered an antiviral, Quercetin has demonstrated effective activity against human immuno-deficiency virus (HIV), Herpes simplex, polio virus and respiratory syncytial virus.
Quercetin and other bioflavonoids (working in conjunction with vitamin C) are said to be useful for bleeding gums, bruising, varicose veins, hemorrhoids and blood clots.
Quercetin is believed to be an excellent anti-inflammatory that is thought to relieve Celiac problems, Eczema, Gout and prostatitis, among many other inflammatory conditions. With regard to Celiac disease, Quercetin interferes with the chemical pathways by which inflammatory hormones are activated and is a useful supportive treatment. Quercetin also stops the multiplication of neutrophils, the immune cells involved in the production of inflammation-causing hormones, preventing the release of the inflammation-causing bodies known as leukotrienes. Because Quercetin counteracts the effects of xanthine oxidase, an enzyme that promotes uric acid production, it helps to combat Gout.
Quercetin increases the production of collagen and fibronectin, which is good news for those of us who want smoother skin with fewer Wrinkles. Recent studies show that bioflavonoids may be a big factor in preventing invasive malignant infection and serious illness.
Quercetin initially gained attention several decades ago when it was found to cause DNA mutations in Bacteria, a possible sign that it might actually contribute to causing Cancer. Animal research done since that time has been inconclusive, and what little evidence there is in humans does not seem to support this idea. Research in recent years has focused on several possible beneficial effects of quercetin, including its potential role in preventing Cancer.
