According to secondary sources, all components of the black bryony plant, including the tubers, are poisonous due to saponin content. Therefore, it is not typically used internally; however, it has been used as a poultice for bruises and inflamed joints. It has been suggested that black bryony be used topically with caution, due to a tendency for the plant to cause painful blisters.
Known Hazards: Studies have isolated calcium oxalate deposits and histamines in the berry juice and rhizomes, which may contribute to skin irritation and contact dermatitis associated with black bryony.
