Quercetin may also be beneficial in the treatment of dysentery, gout, and psoriasis.Quercetin is a phytochemical that is part of the coloring found in the skins of apples and red onions. Quercetin may expel phlegm and arrest oughing, it can also be used as antiasthmatic. Quercetin has anticancer activity, inhibits PI*-kinase activity and slightly inhibits PIP Kinase activity, reduces cancer cell growth via type II estrogen receptors. Quercetin may inhibit histamine release from basophils and mast cells.Quercetin may control the spread of certain viruses within the body. Quercetin may help reduce tissue destruction. Quercetin may also be beneficial in the treatment of dysentery, gout, and psoriasis.

FUNCTION:

Allergies, Asthma, Hay Fever and Hives

In test tubes, quercetin prevents immune cells from releasing histamines, chemicals that cause allergic reactions. On that basis, researchers think that quercetin may help reduce symptoms of allergies, including runny nose, watery eyes, hives, and swelling of the face and lips. However, there is no evidence yet that it works in humans.

Heart Disease

Test tube, animal, and some population based studies suggest that the flavonoids quercetin, resveratrol, and catechins (all found in high concentration in red wine) may help reduce the risk of atherosclerosis (plaque build up in arteries that can lead to heart attack or stroke). These nutrients appear to protect against the damage caused by LDL ("bad") cholesterol and may help prevent death from heart disease. However, most human studies have looked at flavonoids in the diet, not as supplements. Animal studies have used extremely large amounts of flavonoids (more than you could get through a supplement). More studies in people are needed to see if flavonoid supplements can be effective.

High Cholesterol

Test tubes studies show that quercetin prevents damage to LDL cholesterol, and population studies show that people who eat diets high in flavonoids have lower cholesterol. One study found that people who took quercetin and an alcohol free red wine extract (which contains quercetin) had less damage to LDL cholesterol. Another study found that quercetin reduced LDL concentrations in overweight subjects who were at high risk of heart disease. More studies are needed, however, to show whether taking a quercetin supplement will have the same effect.

Hypertension

Studies show that quercetin supplementation reduces blood pressure in people who have hypertension.

Interstitial Cystitis

Two small studies suggested that people with interstitial cystitis might benefit from flavonoids. People with this condition have bladder pain, similar to a bladder infection, and often experience an urgent need to urinate. In both studies, those who took a supplement containing quercetin appeared to have fewer symptoms. However, the studies included other flavonoids, so it isn't known which one might have the most beneficial effect. More and better designed studies are needed.

Prostatitis

Some preliminary evidence indicates that quercetin might reduce symptoms of prostatitis (inflammation of the prostate). One small study found that men who took quercetin had a reduction in symptoms compared to men who took placebo. The study was small, however, and the results need to be confirmed.

Rheumatoid Arthritis (RA)

There are reports of people with RA who had fewer symptoms when they switched from a typical Western diet to a vegan diet with lots of uncooked berries, fruits, vegetables, nuts, roots, seeds, and sprouts containing antioxidants, including quercetin. But there is no evidence that the positive effects were due directly to antioxidants, and no evidence that quercetin supplements would help treat RA.

Cancer

Scientists have long considered quercetin, and other flavonoids contained in fruits and vegetables important in cancer prevention. People who eat more fruits and vegetables tend to have lower risk of some types of cancer. And animal and test tube studies suggest that flavonoids do indeed have anti cancer properties. Quercetin and other flavonoids have been shown in these studies to inhibit the growth of cancer cells from breast, colon, prostate, ovarian, endometrial, and lung tumors. One study even suggests that quercetin is more effective than reservatrol in terms of inhibiting tumor growth. Another found that frequent intake of quercetin rich foods was associated with lower lung cancer risk. The association was even stronger among subjects who smoked more than *0 cigarettes daily. However, more research is needed.
