Quercetin helps lower high blood pressure

October 25, 2007

Epidemiological studies show that Quercetin, a flavanol found in berries, green tea, apple skins and onions, is associated with a reduced risk of developing coronary heart disease, suffering a stroke, and developing some lung cancers. Quercetin supplements have lowered blood pressure in studies of hypertensive animals.

In this newly published study, researchers at the University of Utah, Salt Lake City, gave 19 people with prehypertension (their average was 137/86) and 21 people with stage 1 hypertension (their average was 148/96) 730mg Quercetin for 28 days in a double-blind, placebo-controlled, crossover study; the gold standard for research. Blood pressure was not affected in prehypertensive subjects, but in patients with high blood pressure the average decline was 7/5 mm Hg. The study is published in the November 2007 issue of The Journal of Nutrition.

Commentary by Jerry Hickey, R.Ph. - Quercetin is thought to decrease the risk of lung cancer in people who do not smoke and to help protect the vasculature of smokers. Science is pointing at protective benefits for the pancreas, colon, lungs, and inflamed prostate. It is ideal for allergy sufferers, asthmatics, and diabetics developing sorbitol based cataracts.
