Question

Atropine used at the time of eye testing is obtained from the leaves of
A) Belladona
B) Cinchona
C) Calotropis
D) None of the above

Answer 1

The deadly nightshade plant, also known as belladonna, is so poisonous that eating as few as two berries can kill a child. The plant contains atropine and other dangerous alkaloid chemicals, including scopolamine and hyoscyamine. Despite its toxicity, when used in small quantities atropine has important medical applications.

Deadly nightshade is native to Europe, North Africa, and Western Asia, but the plant grows in North America as well. Its scientific name is Atropa belladonna. All parts of the plant are poisonous.

The flowers of the deadly nightshade plant are bell-shaped and are purple and green in color. The large, oval leaves have pointed tips. Unripe berries are green. As they ripen, the berries become black, shiny, and beautiful. The deadly nightshade is sometimes called devil’s cherries because although the berries look appetizing they are actually very toxic.

So it is belladonna.
