Description of Plant(s) and Culture

Henbane is a biennial plant; the brown, spindle-shaped rootstock produces, in the second year, a dirty-green stem covered with sticky hairs and bearing alternate, sticky oblong-lanceolate, sessile leaves. The funnel-shaped flowers are dull yellow or beige, with purple veins and bases, and grow in one-sided, leafy spikes from July to September. The plant has a fetid odor.

Where Found

Found growing in dry, sandy soils, waste grounds and gravelyards and around the foundations of neglected houses in northern states of the United States, and in Canada and Europe.

Medicinal Properties

Anodyne, antispasmodic, calmative, narcotic, analgesic, diuretic, hypnotic

Biochemical Information

Alkaloids including hyoscyamin and atropine, tannin, choline, traces of essential oil. Contains the narcotics hyoscyamine and scopolamine, which are used as pain killers and to induce sleep. Deadly poison without medical supervision.

Legends, Myths and Stories

Once upon a time, henbane was believed to have aphrodisiac properties and was a main ingredient in love potions. Hamlet’s father was murdered by pouring a distillation of henbane in his ear (perhaps he had complained of earache). Henbane has figured prominently in literature and folklore throughout the ages as a poisonous narcotic similar to belladonna and datura. Therefore, no formulas are attached.

Uses

Historically, henbane was employed primarily in external applications due to its toxicity. An oil derived from the leaves was formulated into lotions intended to ease earache and rheumatism, as well as applied topically to sores and gout. In traditional practice, decoctions or tinctures were occasionally administered internally with the aim of alleviating pain, inducing sleep, reducing perspiration, and addressing nervousness, irritability, coughs, asthma, colitis, and bladder irritation.

Warning

The whole plant is poisonous. Children have been poisoned by eating the seeds or seed pods. Considered very dangerous when taken internally. Use only under medical supervision.
