Hormone Support
Wild Yam
Also known as: Dioscorea villosa, Mexican yam, Colic root, Wild Yam Extract
Wild yam root extract is traditionally used in herbal medicine for hormonal balance and menopausal symptom support, though clinical evidence remains limited. The extract contains diosgenin and other steroidal saponins, but lacks robust RCT evidence confirming efficacy in humans.

Evidence notes
Limited human clinical trial data. Most evidence is traditional use, in vitro studies, or animal models. Diosgenin research is preliminary; human bioavailability and efficacy for hormone support lacks rigorous RCT validation.
Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
