Healthy flavonoid: Quercitin is a flavonoid found in many fruits ; veggies, esp. Onions, apples ; citrus. It may help allergies, reduce blood pressure ; prevent/treat cancer. As a supplement it's poorly absorbed; i advise isoquercitin which is much better absorbed.See http://umm.Edu/health/medical/altmed/supplement/quercetin ; http://www.Quercetinallergy.Info/ ; https://www.Biopharmasci.Com/%5cfile/isoquercetin-2.Pdf.
