Before the [[Middle Ages]], it was used as an [[Anesthesia|anesthetic]] for surgery, and it was used as a poison by early men, [[Ancient Rome|ancient Romans]], including the wives of two Emperors, and by [[Macbeth of Scotland]] before he became a Scottish King. The genus name "atropa" comes from [[Atropos]], one of the three [[Moirae|Fates]] in [[Greek mythology]] (the one who cuts the thread of life), and the name "atropa bella donna" is derived from an admonition in [[Italian language|Italian]] and [[Greek language|Greek]] meaning "do not betray a beautiful lady".<ref name="spiegl"/><ref name="harris"/><ref name="groombridge"/> [[Image:Atropa bella-donna1.jpg|thumb|left|200px|''Atropa belladonna'']] ''Atropa belladonna'' is a branching [[herbaceous]] perennial, often growing as a [[subshrub]], from a fleshy rootstock. Plants grow to {{convert|1.5|m|ft}} tall with {{convert|18|cm|in}} long ovate leaves. The bell-shaped [[flower]]s are dull purple with green tinges and faintly scented. The [[fruit]]s are [[berry|berries]], which are green ripening to a shiny black, and approximately {{convert|1|cm|in}} in diameter. The berries are sweet and are consumed by animals that disperse the [[seed]]s in their droppings, even though the seeds contain toxic [[alkaloid]]s.<ref>{{cite book |author=Kay QON |title=Edible fruits in a cool climate: the evolution and ecology of endozoochory in the European flora.
