The classic case is the rosy periwinkle, found in the tropical forests of Madagascar.
For example the rosy periwinkle (Catharanthus roseus) is the source of alkaloids used to treat childhood leukemia and Hodgkin's disease.
For example, as recently as the 1980s, the plant rosy periwinkle (Catharanthus roseus) gave rise to two important drugs, vinblastine and vincristine, which are used to treat Hodgkin's disease and childhood leukemia, respectively.
For example, willow tree bark contains salicylic acid, aspirin's active agent; cinchona bark has malaria-fighting quinine; foxglove digitalis treats congestive heart failure; rosy periwinkle has leukemia-fighting chemicals; and the evergreen ephedra is commonly used in decongestants.
And yet, no plant indigenous only to Madagascar other than the rosy periwinkle has contributed to any drug approved by the FDA.
