Parts used:—The whole plant.
Uses:—It was formerly used in Europe by professional beggars to produce or maintain blisters or open sores intended to excite sympathy. Roxburgh remarks that it has no native name, and that its properties are apparently unknown. It certainly possesses a very powerful principle, and one would expect to find it taking a place in the practice of herbalism. Water distilled from a decoction retains its acrid character, and, if this be allowed to slowly evaporate, it leaves behind a quantity of highly insoluble crystals of a very inflammable character.
The fresh plant is poisonous, and produces violent effect if taken internally. The bruised leaves form an application to raise blisters, and may also be used to keep open sores caused by vesication, or by other means (Murray).
