Synopsis

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

Polygonum, a genus that includes several species such as Polygonum multiflorum (commonly known as He Shou Wu or Fo-Ti), has a long history of use in traditional Chinese medicine (TCM) for supporting various aspects of health, including the eyes. According to TCM, He Shou Wu is believed to nourish the liver and kidney, organs which are traditionally associated with eye health. It is often included in herbal formulas intended to address visual disturbances, blurry vision, or age-related eye decline.

However, the evidence supporting Polygonum for eye health is primarily based on traditional uses and theoretical frameworks within TCM. There is a lack of robust, peer-reviewed scientific studies directly validating the efficacy of Polygonum species—especially Polygonum multiflorum—in supporting or improving eye function in humans. Most available scientific research on Polygonum focuses on its antioxidant properties, potential anti-aging effects, and liver health, rather than direct ophthalmological outcomes.

In summary, while Polygonum is traditionally used to support the eyes within herbal medicine systems like TCM, there is limited scientific evidence specifically supporting its efficacy for this purpose. Therefore, its use for eye health is justified mainly by tradition rather than by modern clinical research.
