Vinca
its actually purple, not blue
There are at least 86 alkaloids extracted from plants in the Vinca genus. Vincristine, extracted from Vinca rosea Linn. (Catharanthus), is a type of chemotherapy called a vinca alkaloid used to treat some leukemias, lymphomas and childhood cancers, as well as several other types of cancer and some non-cancerous conditions. Vinblastine is a chemical analogue of Vincristine and also used to treat various forms of cancer.
