He Shou Wu (Polygonum multiflorum) is among the very elite healthy-aging, and longevity tonic herbs in the world. It is a longevity and replenishing herb of the highest order. Legend has it that it can return an aging person back to youth. It builds essence, builds blood, and enhances Jing energy. Our He Shou Wu is prepared in the classic and traditional way, slow cooked in a stew of black beans for 36 hours to promote optimum bio-availability and absorption. Its traditional attribute of increasing essence and blood means it also increases female fertility.
