Deadly Nightshade

Atropa belladonna or Atropa bella-donna, commonly known as Belladonna or Deadly Nightshade, is a perennial herbaceous plant in the family Solanaceae, native to Europe, North Africa, and Western Asia. The foliage and berries are extremely toxic, containing tropane alkaloids. These toxins include scopolamine and hyoscyamine which cause a bizarre delirium and hallucinations, and are also used as pharmaceutical anticholinergics. The drug atropine is derived from the plant.

It has a long history of use as a medicine, cosmetic, and poison. Before the Middle Ages, it was used as an anesthetic for surgery; the ancient Romans used it as a poison (the wife of Emperor Augustus and the wife of Claudius both were rumored to have used it to murder contemporaries); and predating this, it was used to make poison-tipped arrows. The genus name "atropa" comes from Atropos, one of the three Fates in Greek mythology, and the name "bella donna" is derived from Italian and means "beautiful woman" because the herb was used in eye-drops by women to dilate the pupils of the eyes to make them appear seductive.

Famous quotes containing the word deadly:

    It is well worth the efforts of a lifetime to have attained knowledge which justifies an attack on the root of all evil—viz. the deadly atheism which asserts that because forms of evil have always existed in society, therefore they must always exist; and that the attainment of a high ideal is a hopeless chimera.
    Elizabeth Blackwell (1821–1910)
