Quercetin is a chemical found naturally in a number of foods (including apples, onions, teas, berries, and red wine) and in some herbs (such as ginkgo biloba and St. John's wort). Quercetin acts as an antioxidant, scavenging free radicals (chemical by-products known to harm cell membranes and damage DNA).
Concern had been expressed about the possible tumor-promoting effect of quercetin. Mild constipation and hair thinning were reported by two of 260 patients taking AS195, which contains red vine leaf extract that is rich in quercetin.
