Periwinkle Leaf, Whole – Catharanthus roseus -100 Gram

Catharanthus roseus (Madagascar periwinkle, or locally known as Sadabahar) whole leaves contain potent biochemicals—most notably vinca alkaloids like vinblastine and vincristine—which are used pharmaceutically to create critical cancer-fighting chemotherapy medications. Raw whole leaves are also used in folk remedies, though direct consumption carries high toxicity risks.
