Wild Yam Extract
A versatile antispasmodic herb often used for menstrual comfort and menopausal support.
Also known as: Dioscorea villosa • Colic Root
Overview
Wild Yam is a plant whose root and bulb have been used in traditional medicine to treat a variety of ailments, particularly those involving spasms and inflammation. It contains diosgenin, a plant-based steroid that was historically used as a starting material for synthesizing hormones like progesterone. While the body cannot convert diosgenin into hormones itself, Wild Yam is valued for its relaxing effects on smooth muscles, making it useful for menstrual cramps and digestive issues.
