flavonoid

Herbal medicine
Any of a family of yellow pigments which are chemically similar to tannins and somewhat similar in use; flavonoids have been used for bruising, hay fever and menorrhagia. 

Nutrition
A family of biologically active polyphenolic compounds found in fruits (in particular in the pulp thereof), vegetables, tea and red wine, which are potent antioxidants and effective platelet inhibitors; a flavonoid-rich diet may protect against atherosclerosis and platelet-mediated thrombosis, due to flavonoids’ platelet-inhibition.
