The recorded history of He Shou Wu as a medicinal herb dates back to the Tang Dynasty, appearing first in He Shou Wu Lu by Li Ao. Legend tells of a man named Mr. He who regained his vitality and dark hair after taking the herb—giving rise to its name, He Shou Wu (literally "Mr. He's Black Hair").
Centuries later, the renowned herbalist Li Shizhen highlighted the root in his classic Compendium of Materia Medica. He noted its ability to strengthen bones and sinews and darken hair, citing its successful use by the Ming Dynasty's Jiajing Emperor. These accounts solidified He Shou Wu's status as a staple in traditional wellness culture.

Raw vs. Processed He Shou Wu: Key Differences

Modern Safety Considerations: Liver Health Notice
While He Shou Wu has a rich history, modern medical evaluations require a cautious approach regarding its oral use:
-
Liver Health Risks: Scientific reports link oral consumption of He Shou Wu—particularly the raw form—to potential liver injury (hepatotoxicity).
-
Usage Advice: Even processed forms should not be taken indiscriminately, in high doses, or over prolonged periods without consulting a qualified healthcare professional or licensed herbalist.
