Mixed Evidence

Folk medicine use; no rigorous clinical trials.

How it works

Aletris root contains steroidal saponins (diosgenin-like compounds), bitter glycosides and alkaloids. Steroidal saponins from Aletris have been historically associated with uterine and tonic effects, though there is no direct evidence that diosgenin is converted into progesterone or other hormones in vivo. Traditional uses include menstrual irregularity, threatened miscarriage and dyspepsia. Modern clinical evidence is essentially absent.

Dosage

No established RDA. Traditional doses are 0.5-2 g of dried root or 2-4 mL of tincture, taken 2-3 times daily.
