belladonna and atropine poisons

Etymology: It, belladonna, fair lady; Gk, Atropos, one of three Fates; L, potio, drink
two powerful poisons obtained from solanaceous plants. Atropine, derived from Atropa belladonna, blocks the effects of acetylcholine in effector organs supplied by postganglionic cholinergic nerves. Belladonna is obtained from the dried leaves of Atropa belladonna, also known as deadly nightshade, or of Atropa acuminata, a source of alkaloids that are converted to atropine. Atropine sulfate is commonly used in ophthalmological applications and as an antispasmodic.
