Henban From the family Solanaceae
This native of Europe has become widely distributed worldwide and is found growing -J- on waste ground or roadsides on well-drained sandy or chalk soils. Two famous deaths are attributed to henbane. Hamlet's father was murdered by a distillation of henbane being poured in his ear, and in 1910 Dr Crippen used hyoscine, which is extracted from the plant, to murder his wife. Every part of the plant is toxic.
Henbane has been considered to have aphrodisiac properties and is the main ingredient in some love potions and witches' brews. It was also placed by the hinges of outer doors to
protect against sorcery.
