The term "oleander" refers to two plant species, Nerium oleander (common oleander) and Thevetia peruviana (yellow oleander), which grow in temperate climates throughout the world. Both species contain chemicals called "cardiac glycosides" that have effects similar to the heart drug digoxin. Both species can be toxic when taken by mouth with many documented reports of deaths.

These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
Laboratory studies of oleander suggest possible anti-cancer effects, although reliable research in humans is not currently available. There are reports that long-term use of oleander may have positive effects in patients with leiomyosarcoma, Ewing's sarcoma, prostate cancer, or breast cancer. More research is needed before a recommendation can be made.
