Resveratrol

A phytoalexin produced naturally by several plants when under attack by pathogens such as bacteria or fungi. Found in the skin of grapes, peanuts, berries of vaccinum species, some pines and the roots and stalks of giant knotweed and Japanese knotweed, it has been linked to reducing blood sugar levels and recent scientific study has shown that it stimulates the ‘longevity’ gene, which could help organisms live up to 20 per cent longer.
