Atropa belladonna or
Atropa bella-donna, commonly known as
belladonna or
deadly nightshade, is a
perennial herbaceous plant in the tomato family
Solanaceae, native to
Europe,
North Africa,
Western Asia, and introduced in some parts of Canada and the United States. The foliage and
berries are extremely
toxic, containing
tropane alkaloids. These toxins include
atropine,
scopolamine and
hyoscyamine, which cause a bizarre
delirium and
hallucinations, and are also used as pharmaceutical
anticholinergics.
