The small greenish white flowers are gathered into umbellate cymose inflorescences. The fruit is a berry, with two to eight very hard disk-shaped seeds with shiny, silky hairs. The nux vomica is native to the tropical forests of Asia and northern Australia; it is cultivated in the tropics of Africa. Like several other closely related species, it contains poisonous alkaloids (strychnine, brucine), mainly in the seeds. Strychnine (nitrate) and galenicals (the dried extract and tincture of nux vomica) are used in medicine and veterinary medicine as tonics to treat lowered metabolism, rapid fatigability, hypotension, weakened cardiac activity (resulting from intoxication and infection), pareses and paralyses, and atony of the stomach. The genus Strychnos contains 150 to 200 species, which are common to the tropics of both hemispheres. Some species are used as a source of the arrow poison curare, which contains alkaloids called curarines; others are used to treat snakebites and to purify drinking water.
