Wild yam (Dioscorea villosa)

Tier 3 — weak evidence · Menopause · Hormonal claims

Marketed as a natural progesterone source for menopause, but your body cannot convert the diosgenin in wild yam into progesterone. That conversion requires industrial laboratory processes. No clinical trial has demonstrated hormonal benefits from wild yam supplements or creams. Some products secretly contain added synthetic progesterone, which is why some users report effects. Not recommended for hormone management.

Dose: Not recommended; body cannot convert diosgenin to progesterone; no effective dose established
