Legends, Myths and Stories

Bryony was considered a wicked plant in the Middle Ages. Medieval con men passed off carved bryony roots as mandrakes, making great profits and deceiving many people, including childless women who bought the root as a fertility drug or charm.

Uses

Historically, white bryony was regarded by herbalists as a strong purgative. In German folk tradition, the rootstock was prepared by hollowing it out, filling it with beer, and subsequently drinking the liquid to address constipation. Traditional practitioners also employed the dried root for coughs, shortness of breath, rheumatism, dizziness, dropsy, cramps, and kidney stones.

Externally, herbal preparations were applied with the intention of cleansing sores, wounds, bruises, and boils, as well as addressing sunburn and freckles.

Warning

White byrony purges violently; should have medical supervision. The rootstock is poisonous in large doses. The berries are very poisonous. 40 berries will kill an adult; 15 berries will kill a child. Another variety: Red bryony (B. dioica) contains a dangerously poisonous resin. Do not use either Red or White Byrony without medical supervision.
