“…Furthermore, these cases should be noted: Shikonin (from Lithospermum erythrorhizon), curcuminoid (from Curcuma longa), camptothecin (from Camptotheca acuminate), and ingenol mebutate (from Euphobia peplus), Trastuzumab emtansine (Kadcyla) which is an antibody conjugated to a synthetic derivative of the cytotoxic principle of the Ethiopian plant Maytenus ovatus and used to treat breast cancer. 3 Although more than half of the anticancer compounds used to treat cancer are obtained from plant sources or marine and microorganisms, it seems that there is still little knowledge about the power of natural resources in the face of incurable diseases such as cancer. 4 Finally, the fewer side effects, availability, and lower cost of drugs obtained from plants compared to synthetic samples, especially for cancer patients who have weakened immune systems, make alternative medicine a very important issue.…”
