Digitalis for congestive heart failure was first isolated from the foxglove plant. Various antibiotics (penicillin) and anticancer agents (taxol) are derived from natural product sources. There are numerous other examples. 

William Withering, an English physician with a strong interest in botany, was the first to introduce the diuretic digitalis (from the foxglove plant Digitalis purpurea) into common medical practice for the treatment...
