He Shou Wu has been prized for centuries because of its ability to prevent premature aging and enhance longevity and youthfulness. According to Chinese theory, He Shou Wu restores and nourishes the primal energy of the body known as "Jing" or "Essence." By nourishing that root energy the skeletal system, the muscular system, and the nervous system are tonified and energized. He Shou Wu has also been shown to increase the body's level of SOD (superoxide dismutase), a critical antioxidant that the body produces to fight free radical damage. SOD helps the body maintain proper cellular function and replication with protection against DNA damage. He Shou Wu is very rich in the mineral Zinc, which supports reproductive and sexual energy, and iron, which supports healthy blood building. 250 gram packet 125 servings per packet Ideal for: Anyone who want to support longevity and youthfulness, build blood.
