Fo-Ti for Hair
A legendary herb in Traditional Chinese Medicine believed to reverse gray hair and combat hair loss.
Also known as: He Shou Wu • Polygonum Multiflorum
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.
| Purpose | Dose | Notes |
|---|---|---|
| Hair Health and Anti-Aging | 500-1000mg/day of extract | Always start with a lower dose to assess tolerance. Ensure the product is from a reputable source and specifies it is prepared root. |
Best Time to Take
Can be taken with or without food.
With or Without Food
Not required, but can be taken with food to minimize potential GI upset.
