Resveratrol was identified and extracted for the first time from the white veratrum Veratrum album L. var grandiflorum) in 1939 by the Japanese researcher M. TAKAOKA. Its name comes from the plant from which it was isolated. This natural polyphenol of the stilbene class is also present in grapes, bilberries, rhubarb, blackberries and peanuts. It is also found in Japanese knotweed, an East Asian herbaceous plant used in traditional Chinese and Japanese medicine to fight against various pathologies including inflammatory and cardiovascular diseases. This molecule is present in two forms: cis-resveratrol and trans-resveratrol, the most abundant form in nature and the most active. Resveratrol is known for its powerful antioxidant activity, acting at two levels: it neutralizes existing free radicals and prevents others from forming. It thus has a dual preventive and corrective action against sources of oxidation, which helps limit premature aging of the skin. Studies have also shown that this active ingredient can reduce inflammatory responses by inhibiting the synthesis and release of pro-inflammatory mediators. Finally, resveratrol also has anti-microbial activity.
