Uses based on scientific evidence.:

High cholesterol:

 Animal studies have shown that wild yam can reduce absorption of cholesterol from the gut. Early studies in humans have shown changes in the levels of certain sub-types of cholesterol, including decreases in low-density lipoprotein (LDL, or "bad cholesterol") and triglycerides,and increases in high-density lipoprotein (HDL, or "good cholesterol"). However, no changes in the total amount of blood cholesterol have been found. More studies are needed in this area.

 Menopausal symptoms:

 Most studies have not shown a benefit from wild yam given by mouth or used as a vaginal cream, in reducing menopausal symptoms. However, replacing two thirds of staple food with yam for 30 days was shown to improve the status of sex hormones, lipids, and antioxidants in a recent study in postmenopausal women. The authors suggest that these effects might reduce the risk of breast cancer and cardiovascular diseases in postmenopausal women. Further research is needed before a recommendation can be made.

 Hormonal properties (to mimic estrogen, progesterone, or DHEA):

 Despite popular belief, no natural progestins, estrogens, or other reproductive hormones are found in wild yam. Its active ingredient, diosgenin, is not converted to hormones in the human body. Artificial progesterone has been added to some wild yam products. The belief that there are hormones in wild yam may be due to the historical fact that progesterone, androgens, and cortisone were chemically manufactured from Mexican wild yam in the 1960s.

 Wild yam extract,the roots of wild yams were used in the first commercial production of oral contraceptives, topical hormones, androgens, estrogens, progesterones, and other sex hormones. Diosgenin, a component of wild yam, is promoted as a natural precursor to dehydroepiandrosterone (DHEA). Some wild-yam products are promoted as "natural DHEA." Although diosgenin can be converted to steroidal compounds, including DHEA, in the laboratory, this chemical synthesis does not occur in the human body. So taking wild-yam extracts will not increase DHEA levels in humans. There is no research showing wild yam has any effectiveness when applied topically on skin. If anything, the studies that do exist have demonstrated that topical application of wild yam has little to no effect on menopausal symptoms.
