Diosgenin

Diosgenin is a plant steroid found in certain medicinal herbs, such as wild yam and fenugreek.  It’s a plant steroid that bears some resemblance to human sex steroids, and can serve as a precursor for their synthesis, but the necessary conversion steps take place only in the laboratory – not the human body.  Although diosgenin has potential medical uses (such as reducing serum cholesterol), it does not have any known hormonal effects when consumed in supplemental form.
