Dioscorea, commonly known as wild yam, has a long history of traditional use for various women’s health issues, including menstrual irregularity. In traditional medicine systems such as those practiced by Native American and Chinese herbalists, wild yam root was often employed to address symptoms associated with the menstrual cycle, including cramps, irregular bleeding, and menopausal symptoms. The rationale behind its use largely stems from the presence of diosgenin, a plant steroid that can be chemically converted in the laboratory to progesterone and other steroids. However, it is important to note that the human body does not convert diosgenin into progesterone naturally; this transformation requires industrial processes. Despite this, the traditional use of wild yam as a women’s tonic persists, and it is still found in some herbal blends marketed for menstrual support.

From a scientific perspective, the evidence supporting wild yam’s efficacy for menstrual irregularity is limited and mostly anecdotal. A few small studies and animal experiments have suggested a potential for antispasmodic or anti-inflammatory effects, which could theoretically help with menstrual cramps, but robust clinical research in humans is lacking. Major reviews and authoritative sources, such as the National Center for Complementary and Integrative Health (NCCIH), state that there is insufficient scientific evidence to support wild yam for hormone-related conditions. Thus, its use for menstrual irregularity remains primarily justified by tradition rather than strong scientific validation.
