Sweet, slightly bitter, and warming, He Shou Wu is used to nourish the Liver and Kidneys, tonify blood, and support healthy aging. Its reputation in traditional lore for restoring gray hair to black has made it especially famous in herbal formulas for vitality and rejuvenation.
What Is Chinese Knotweed Root?

In TCM, it is classified as bitter, sweet, astringent, and slightly warm, entering the Liver and Kidney meridians. It is traditionally used to tonify Liver and Kidney yin and blood, secure essence, strengthen tendons and bones, and moisten the intestines.
