Quercetin is a flavonoid, or bioflavonoid, a substance that is found in plants. It is also an antioxidant, which means it protects cells against free radical oxygen molecules, claims UMMC. In studies, it has been found to inhibit the release of histamines, substances that cause the symptoms of allergies. Quercetin may also lower levels of LDL, the bad cholesterol that leads to dangerous plaque build-up in the arteries.
As of 2015, other studies show that quercetin may be useful in lowering high blood pressure and can ease the symptoms of inflammation of the prostate as well as interstitial cystitis. Quercetin also seems to lower the risk of certain types of cancers, especially reproductive cancers and cancers of the lungs and colon, according to UMMC. Smokers who eat foods abundant in quercetin seem to have a lower risk of developing lung cancer.
Studies also found that quercetin was effective in combating viruses such as the polio and Herpes simplex virus, and helped to prevent cataracts in rodents suffering from diabetes, according to the NYU Langone Medical Center.Learn more about Vitamins & Supplements
