The Pacific Yew and the Periwinkle



The chemotherapy drug paclitaxel (Taxol), used in breast, ovarian and lung cancer treatment, is derived from Taxus brevifolia, the Pacific Yew tree.

Vincristine (brand name, Oncovin), also known as leurocristine, is a vinca alkaloid from the Catharanthus roseus (Madagascar periwinkle), formerly Vinca rosea and hence its name. It is a mitotic inhibitor, and is used in cancer chemotherapy.
