Catharanthus roseus is commonly known as Sadabahar, as it is always in bloom. It is a tropical/subtropical plant spread throughout the world. The anti-hyperglycemic activity of this plant was recognized long before, and this attracted several researchers to do extensive research on this plant. The practice of using the leaf decoction as a cure for diabetes has been an age old practice. Vincristine and vinblastine are the two chemical constituents of this evergreen shrub, which make it famous for its anti-cancer activity.
