Medicinal Uses

The whole baneberry plant, but especially the root, is pain-relieving, antirheumatic, and has agents that promote secretion of milk and cause reddening or irritation when applied to the skin. The plant was often used medicinally by North American Indian tribes, though modern users should be aware of the plants potential toxicity. A tea made from the root was used as an appetizer, in the treatment of stomach pains, coughs, colds, menstrual irregularities, post partum pains, to increase milk flow and as a purgative after childbirth.

Poisonous Properties

Great caution should be employed if using this plant internally, the rootstock is a violent purgative, irritant and emetic. All parts of the plant are toxic, containing the poison protoanemonin, apparently acting upon the heart. As few as 2 berries can cause severe cramps, headaches, vomiting, bloody diarrhea and/or dizziness. Severe poisoning results in paralysis of the respiratory system and cardiac arrest.
