Description: Resveratrol is a naturally occurringphytoalexin produced by some higher plants in response to injury orfungal infection. Phytoalexins are chemical substances produced byplants as a defense against infection by pathogenic microorganisms,such as fungi. Resveratrol may also have alexin-like activity forhumans. Epidemiological, in vitro and animal studies suggest that ahigh resveratrol intake is associated with a reduced incidence ofcardiovascular disease, and a reduced risk for cancer.
