Jesuit's Bark, later called Peruvian Bark (fever-wood) is the bark of the cinchona or chinchona tree. Its existence was brought to Europeans by a Jesuit about 1535 but it was not generally used until 1633 when the wife of the viceroy of Peru was cured of a fever with it. She brought it to Europe in 1639 and it came into general use in 1680. The active constituent of Jesuit's Bark is quinine. Research Jesuit's Bark
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 Contrary to popular opinion, the use of quinine has not entirely superseded the use of quinine containing barks in medicine, bark is still used in the Caribbean and South America for the treatment of fever and other ills.
