Cragg GM1, Newman DJ, Plants as a source of anti-cancer agents; J Ethnopharmacol. 2005 Aug 22;100(1-2):72-9.
Plant-derived compounds have been an important source of several clinically useful anti-cancer agents.
Cancer drugs/agents made from plants include vinblastine, vincristine, the camptothecin derivatives, topotecan and irinotecan, etoposide, derived from epipodophyllotoxin, and paclitaxel (taxol ).
A number of promising new agents are in clinical development based on selective activity against cancer-related molecular targets, including flavopiridol and combretastin A4 phosphate, while some agents which failed in earlier clinical studies are stimulating renewed interest.
Cancer curing plants whose properties have been properly scientifically researched include Madagascar Periwinkle,May Apple and Pacific Yew.
