Hyoscyamus Niger

Commonly known as Henbane. In Greek legend the dead in Hades were crowned with Henbane as they wandered beside the Styx. The plant has been used since antiquity in magic and diabolism for its power of causing delirium and hallucinations.

In poisonous doses, poor vision, dizziness, sleepiness are often followed by delirium and convulsions. The active constituents are Hyoseyamine, Atropine and Hyoseine.

 Similar to Belladonna in its medicinal uses, however the added presence of Hyoscine gives it the properties of reducing secretions and relax spasm of involuntary muscles.

It has been employed in hysteria, pain and rheumatism.  It was also used extensively in insane asylums for treating mania and delirium tremens.
