Rating (out of 5): 2

Polygonum is a large genus that includes several species, such as Polygonum multiflorum (also known as He Shou Wu or Fo-Ti) and Polygonum aviculare (knotgrass). The use of Polygonum to support the reproductive system is primarily rooted in traditional herbal medicine, particularly in Traditional Chinese Medicine (TCM). Polygonum multiflorum is especially well-known for its reputed benefits in supporting reproductive health, longevity, and vitality. In TCM, He Shou Wu is traditionally believed to nourish the liver and kidneys, organs considered fundamental to reproductive health and sexual vitality. It has been used to address issues such as infertility, low libido, and menstrual irregularities. These uses are mainly based on longstanding historical practices and anecdotal evidence rather than robust scientific studies.

While some laboratory research has investigated the phytochemicals present in various Polygonum species, there is limited direct clinical evidence supporting their efficacy for reproductive health in humans. Most of the available scientific studies focus on antioxidant or anti-inflammatory effects, with only a few animal studies suggesting possible fertility benefits. Therefore, the use of Polygonum to support the reproductive system is best characterized as traditional, with a low-to-moderate level of supporting evidence (rated 2 out of 5).
