The Jesuits were members of the Society of Jesus. During the 1600’s this medieval society (also called the Company) found a remedy for malaria in the bark of the quina tree, now the source of quinine. Protestants continued dieing from malaria in great numbers because they distrusted the Jesuits, thinking them only trying to poison them with the new concoction.
