He Shou Wu (Fo-Ti / Polygonum multiflorum): Traditional Jing Preservation, Stilbenes, and Hepatic Cautions

The Black-Haired Root of Daoist Folklore

Legend tells of herbalist Mr. He, who consumed wild roots of Polygonum multiflorum and restored his youthful vitality, black hair, and virility—giving the plant its Chinese name He Shou Wu (何首烏)—"Black-Haired Mr. He".

1. Crucial Distinction: Raw vs. Prepared Fo-Ti

• Raw He Shou Wu (Sheng Shou Wu): Unprocessed; contains high concentrations of emodin anthraquinones that act as harsh laxatives and carry significant risk of hepatotoxicity.
• Prepared He Shou Wu (Zhi Shou Wu): Stewed extensively with black bean broth and yellow wine, converting harsh anthraquinones into protective tetrahydroxystilbene-2-O-$\beta$-D-glucoside (TSG), a powerful antioxidant compound resembling resveratrol.

2. Jing (Vital Essence) in Eastern Longevity

In Daoist theory, prepared He Shou Wu tonifies the Kidneys and Liver, nourishing the deep ancestral reservoir of life vitality (Jing).
