The bulb and roots of wild yams contain a chemical called diosgenin, which can influence the production of several useful hormones in humans, such as Estrogen or dehydroepiandrosterone (DHEA).
Consuming wild yam may be a natural way of promoting these hormones in the body, which could have certain medical benefits. Wild yam also contains a chemical called dioscoretine, which helps with the regulation of blood sugar levels.
Wild yam could be useful in regulating blood sugar levels in people with diabetes. Consuming wild yam is rare due to its bitter taste. However, it is available in a variety of formulations, including, tablet, capsule, tincture, cream, tea, and powder.
