Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Fo-Ti (Polygonum multiflorum), also known as He Shou Wu, is a traditional Chinese herb historically used to support hair health and purported to prevent or reverse graying. According to Traditional Chinese Medicine (TCM), Fo-Ti is believed to nourish the liver and kidneys, organs thought to influence hair vitality in TCM theory. Its use for promoting hair growth and restoring hair color dates back centuries, with anecdotal reports and classical texts frequently citing its benefits for maintaining youthful hair. However, scientific evidence supporting these claims remains limited. While some laboratory studies suggest potential antioxidant and anti-inflammatory properties, robust human clinical trials demonstrating clear benefits for hair growth or prevention of hair loss are lacking. Most claims about Fo-Ti’s effects on hair are rooted in tradition rather than rigorous science. Moreover, there are safety concerns with long-term or high-dose use, as liver toxicity has been reported in some cases. In summary, while Fo-Ti enjoys a long history in traditional herbal practice for hair support, scientific validation for these effects is currently weak, justifying a moderate evidence rating based primarily on tradition rather than empirical research.
