Fo-Ti (He Shou Wu) Fo-Ti root, or He Shou Wu (pronounced huh – similar to English “huh”, but not as open – show woo) is one of the most popular and highly revered tonic herbs in Asian herbalism. He Shou Wu is the prepared tuberous root of Polygonum multiflorum, a plant that grows in the mountains of central and southern China. It shares the position as the primary essence (Jing) tonic of Chinese herbalism with the Goji berry. By virtue of its ability to accumulate tremendous quantities of Qi into its root, this herb can tonify the human and animal organs and can tonify and nourish the blood. He Shou Wu is not a stimulant. However, it is one of the greatest energy tonics known to mankind. Its action is cumulative, as any truly healthy tonic dietary supplement would be. Because it is a very mild sedative, it will calm the nervous system. So it can be said that He Shou Wu is both energizing and calming. That is the magic of a great tonic herb.
