Traditional uses

For generations, Native American nations of the eastern woodlands and later the granny-women and midwives of Appalachia turned to the bitter root of Aletris farinosa as a tonic for a troubled stomach and a trusted support through a woman's cycles and pregnancy. Its common names tell its story plainly: colic root for its digestive use, and unicorn root for the odd, single spike of mealy white flowers it sends up each summer. By the nineteenth century it had earned a steady place in American Eclectic and physiomedical practice, where physicians listed it among the native tonics worth keeping on the dispensary shelf. It was valued less as a dramatic cure and more as a slow, steadying presence, the kind of root a household kept on hand rather than reached for only in emergencies.

Did you know?

Aletris farinosa is frequently mixed up with "false unicorn root" (Chamaelirium luteum), an entirely different plant from a different genus that shares a similar folk reputation for women's health, a mix-up that has muddled herb books and apothecary shelves for well over a century.

Safety

Use only properly dried root; the fresh root is acrid and can cause nausea, vomiting, or narcotic-like effects in quantity. Avoid during pregnancy and breastfeeding.
