Resveratrol is a polyphenolic phytoalexin which is produced in plants with the help of the enzyme stilbene synthase, and which has anti-fungal properties. It is found in the skins of certain red grapes, in peanuts, blueberries, some pines (Scots pine, eastern white pine) and the roots and stalks of Japanese knotweed (hu zhang in China) and giant knotweed. Resveratrol was first isolated from an extract of the Peruvian legume Cassia quinquangulata in 1974. It is now available as a mass-produced nutritional supplement but not as a therapeutic agent (though it is now registered as an investigational drug). The supplement, first sourced as ground dried red grape skins, has shifted somewhat to include certain of the knotweeds as a raw material.
