PARTS TRADITIONALLY USED
Dried roots and rhizomes.
CULINARY USES
None; it is extremely bitter and potentially emetic if not properly aged.
TRADITIONAL USES
Used extensively by Native Americans and early American physicians (like the eponymous Dr. Culver) as a strong purgative, laxative, and hepatic tonic. Fresh root is considered too violent; dried root was used for liver and bowel issues.
GROWING / HARVESTING
Grows in moist to mesic prairies, woods, and thickets. Roots are dug in the autumn after the plant dies back, then carefully dried and aged (often for a year) to mellow their harsh action.
SAFETY / CAUTION
Fresh root is an aggressive emetic and cathartic. Even dried, it is a powerful laxative and should be used with extreme care. Contraindicated in pregnancy and intestinal inflammation. Always consult your doctor before using this or any herbal remedy.
