Description:Resveratrol is a naturally occurring phytoalexin produced by some higher plants in response to injury or fungal infection. Phytoalexins are chemical substances produced by plants as a defense against infection by pathogenic microorganisms, such as fungi. Alexin is from the Greek, meaning to ward off or to protect. Resveratrol may also have alexin-like activity for humans. Epidemiological, in vitro and animal studies suggest that a high resveretrol intake is associated with a reduced incidence of cardiovascular disease, and a reduced risk for cancer.
