Atropa belladonna is one of the most poisonous plants known, with all parts of the plant containing toxic tropane alkaloids. A. belladonna extracts have been used since ancient times as both a poison and as a cosmetic agent for dilation of the pupils. A number of the A. belladonna alkaloids are used in modern medicine as anticholinergic agents. Atropine is used for a wide variety of conditions, including bradychardia and Wenckebach block. Scopolamine (levo-duboisine, hyoscine) is used to treat motion sickness in the form of a patch. Hyoscyamine alleviates the symptoms of various gastrointestinal disorders. Donnatal combines A. belladonna alkaloids hyoscyamine, atropine and scopolamine with phenobarbital to treat intestinal cramping.
