Explanation

Quinine, obtained from Cinchona ledgeriana, is a very commonly used anti-malarial drug. Reserpine, an alkaloid obtained from the roots of Rauwolfia serpentina, is used as Tranquilizer. Caffeine is a bitter, white crystalline xanthine alkaloid and a stimulant drug obtained from Camellia sinensis. In humans, caffeine acts as a central nervous system stimulant, temporarily warding off drowsiness and restoring alertness. Atropine, an anticholinergic agent obtained from Atropa belladonna, is used as premedication in anaesthesia to reduce upper respiratory secretions.
