Wild yam has been used in traditional herbal medicine for its supportive role in women's health. Derived from the root of the wild yam plant (Dioscora villosa), this botanical has been valued for centuries by indigenous and early American herbalists for its soothing and anti-inflammatory properties. Today, it is commonly discussed in relation to hormone support, digestive comfort, and relief from menstrual discomfort. In this article, we'll explore the health benefits and supplement options available.
Wild Yam Benefits
Wild yam has a balancing effect on the female hormonal system. It contains precursor molecules to the human hormone, progesterone. Progesterone dominates the second half of the menstrual cycle, the time when the body is preparing for a possible pregnancy.
In today’s world, many women experience health problems due to low progesterone or estrogen that is not properly balanced with progesterone. It is used for conditions like PMS, water retention, menopausal complaints, infertility and low libido.
Diosgenin is the steroidal molecule from which some pharmaceutical progesterone is derived. However, researchers have yet to find a pathway through which diosgenin can be converted into progesterone in the human body. Thus, many medical researchers believe that wild yam supplements have no medicinal value. Many women would disagree, and perhaps there are undiscovered molecules or pathways that will be able to explain the activity of this herb.
Wild Yam Supplement Options
These supplements can be purchased as a loose herb, tincture or encapsulated herb. Better-quality supplements are standardized to ensure the product contains wild yam and has some active properties. Creams with this ingredient are also a popular form of administration.
It is often grown with fertilizers and pesticides that may not be removed from supplements. Choose organic varieties or inquire with the manufacturer to ensure that the raw ingredients are properly prepared and grown.
Important Information
Although natural health practitioners sometimes recommend it to pregnant women, wild yams should be used cautiously in these cases. It may alter hormonal cycles and theoretically can interfere with birth control pills and hormone replacement therapy. Don't use this nutrient if you have a history of hormone-dependent tumours, stroke or embolus. It may interact with steroidal medications.
I never heard of wild yam before this article and find it cool that this herb has a "balancing" effect on the female hormonal system with the mechanism being that it contains precursor molecules to the human hormone, progesterone.
There's a general awareness of low (or high!) estrogen causing many women to experience health problems so thank you for bringing attention to the importance of considering progesterone as well.
One thing I am confused about: you never say if or how diosgenin derives fom wild yam. Could you please explain the connection? Is it the progesterone precursor that you discus at the article outset?
Hello Rachel,
Thank you for your comment. Yes, diosgenin is the progesterone precursor discussed in the article.
Diosgenin is a compound that is naturally present in certain plants, and most notably, wild yam. It belongs to the steroidal saponins family.
While it does not supply hormonally active progesterone, it is a phytoestrogen that functions as a precursor in the body's hormonal pathways, and thus stimulates the synthesis of progesterone and other steroid hormones like cortisone and pregnenolone.
Extracting diosgenin from wild yam involves several steps: harvesting roots during dormancy, cleaning to remove debris, chopping or grinding for increased surface area, then extracting using methods such as solvent extraction or steam distillation, commonly employing solvents like ethanol or methanol.
Filtration then separates diosgenin-containing solvent from solid material, followed by concentration through solvent evaporation. Purification steps may follow, removing impurities via techniques like chromatography. The resulting purified diosgenin is dried to eliminate residual solvent and water, yielding a powdered form that can be used in dietary supplements and cosmetics.
