Here is some info:
Quinine was extracted from the bark of the South American cinchona tree and was isolated and named in 1817.
The medicinally active bark, which is stripped from the tree, dried and powdered, includes other alkaloids that are closely related to quinine but react differently in treating malaria. As a medicinal herb, cinchona bark is also known as Jesuit's bark or Peruvian bark.
