PARTS TRADITIONALLY USED
Rhizomes (roots).
CULINARY USES
While related to edible yams, the root of Dioscorea villosa is bitter, tough, and mostly used medicinally, not as food.
TRADITIONAL USES
Renowned for its antispasmodic properties. Traditionally used to treat intestinal colic, gallstone pain, menstrual cramps, and joint pain. It contains diosgenin, a precursor once used in the lab to synthesize early birth control pills, though the body does not convert it into hormones directly.
GROWING / HARVESTING
Grows in moist woods and thickets. The long, knotty rhizomes are harvested in the fall.
SAFETY / CAUTION
Generally safe in moderate amounts, but large doses may cause nausea. Avoid during pregnancy and nursing, or if you have a hormone-sensitive condition. Always consult your doctor before using.
