Is Japanese knotweed the same as resveratrol?
Resveratrol is a stilbenoid compound found predominantly in Japanese knotweed roots, functioning as a plant defence substance with antioxidant activity. In the UK, trans-resveratrol is authorised as a novel food with a maximum daily intake of 150 mg for adults; it is regulated as a food supplement, not a medicine. Grapes and wine are the most common dietary sources of resveratrol, and the content is often related to variety, origin, ripeness, brewing method, and grape fermentation time.Polygonum cuspidatum is a good source of resveratrol, provided an efficient method of extraction is developed. The main difference between resveratrol extracted from Polygonum cuspidatum and resveratrol extracted from grapes is the composition of the extract.Japanese Knotweed Extract (Polygonum cuspidatum) contains resveratrol which shows anti-oxidant and anti-inflammatory effects by inducing a significant reduction of the generation of reactive oxygen species and inflammation-inducing cytokines.Food sources Resveratrol is found in grapes, wine, grape juice, peanuts, cocoa, and berries of Vaccinium species, including blueberries, bilberries, and cranberries (140-143).While peanuts and grapes contain low levels of the stilbenes, Itadori tea and red wine both supply relatively high concentrations of resveratrol. For people who do not consume alcohol, Itadori tea may be a suitable substitute for red wine.
What are the dangers of Japanese knotweed?
