Evidence supporting the use of: Dioscorea oppositifolia
For the body system: Reproductive System
Synopsis
Source of validity: Traditional
Rating (out of 5): 2
Dioscorea oppositifolia, commonly known as Chinese yam or nagaimo, has a longstanding history of use in traditional Chinese medicine (TCM) to support the reproductive system. In TCM, it is believed to nourish "kidney yin," which is associated with reproductive health, vitality, and hormonal balance. Chinese yam is frequently included in formulas intended to address issues such as infertility, irregular menstruation, and menopausal symptoms. However, most of the support for these uses comes from traditional practice and anecdotal evidence rather than rigorous scientific research.
While Dioscorea species, particularly Dioscorea villosa (wild yam), have been studied for their diosgenin content—a compound that can be converted into steroidal hormones in the laboratory—there is little evidence that consuming the plant directly produces these effects in humans. Research on Dioscorea oppositifolia itself is limited, and the available studies have not conclusively demonstrated its efficacy in supporting the reproductive system. Thus, the use of Dioscorea oppositifolia for reproductive health is primarily supported by traditional knowledge rather than scientific validation.
