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.^[1] 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.
