Overview

Fo-Ti, also known as He Shou Wu, is a popular herb in Traditional Chinese Medicine (TCM) with a long history of use as a longevity and anti-aging tonic. Its name translates to "the black-haired Mr. He." It is thought to work by stimulating hair follicles, promoting the transition from the telogen (resting) phase to the anagen (growing) phase of the hair cycle. It is also believed to enhance melanin production, which could help in maintaining natural hair color.

Key Benefits

Promotes Hair Growth

Studies suggest Fo-Ti can induce the anagen (growth) phase in dormant hair follicles, leading to increased hair growth.

May Restore Hair Color

Traditionally, Fo-Ti is used to combat graying hair. It is thought to support melanin synthesis, the pigment responsible for hair color.

Overall Rejuvenation Tonic

In TCM, it is considered a blood and kidney tonic, which is believed to support overall vitality and healthy aging, indirectly benefiting hair.

Dosage & How to Take

It is crucial to use prepared (cured) Fo-Ti, not the raw, unprocessed root.
