Jesuit's bark

Jesuit's bark, also known as cinchona bark, Peruvian bark or China bark, is a former remedy for malaria, as the bark contains quinine used to treat the disease. The bark of several species of the genus Cinchona, family Rubiaceae indigenous to the western Andes of South America, was introduced to Jesuit missionaries as a traditional treatment for malaria by indigenous people in Peru during the 17th century.
