Quinine is an anti-malaria drug derived from the bark of the cinchona tree (Jesuit's Bark). It was first discovered in 1820 by Pelletier and Caventou and the first artificial quinine was prepared in 1865 by Scott. Contrary to popular opinion, the use of quinine has not entirely superseded the use of quinine containing barks in medicine, bark is still used in the Caribbean and South America for the treatment of fever and other ills.
