Virginia Snakeroot

Aristolochia serpentaria

Virginia snakeroot earned its name and its reputation the same way: European settlers, watching Indigenous healers of the eastern woodlands, came to believe the gnarled, fibrous root could counter the bite of a venomous snake, a belief reinforced by the old doctrine of signatures, since the twisted rhizome itself was thought to resemble a small serpent. For generations it was steeped as a bitter tonic for fevers, colds, and sluggish digestion, and it found its way into nineteenth century apothecary cabinets and official pharmacopoeias as a stimulating bitter. That history matters, but it belongs firmly to the past. Modern research has shown the plant to be genuinely dangerous, and it has been retired from responsible herbal practice.

Safety.

Aristolochia serpentaria contains aristolochic acid, a compound classified by the International Agency for Research on Cancer as a Group 1 human carcinogen and a potent nephrotoxin. Ingesting any part of this plant, in any preparation or amount, has been linked to irreversible kidney failure and urinary tract cancers, sometimes appearing years after exposure, a condition now known as aristolochic acid nephropathy. Because of this, the FDA has warned consumers to avoid all Aristolochia-containing products, and many countries restrict or ban their sale outright. It is not safe during pregnancy, is not safe for anyone regardless of health status, and has no established safe dose. This plant should never be ingested, brewed, or taken internally in any form. If you are drawn to Virginia snakeroot, enjoy it as a native woodland plant in the garden or in botanical history, and please speak with a qualified healthcare provider or medical toxicologist before considering any Aristolochia product, rather than using this or any reference as a guide for use.
