Oleander has proven to be one of the most potent cancer fighters and immune boosters known to man. It is effective for a broad range of conditions including hepatitis-C, HIV/AIDS, and just about every kind of cancers (the oleander based supplement from South Africa, Sutherlandia OPC, has had over 90% success agoinst cancer and 100% success against HIV). With some cancers, such as pancreatic and melanoma, it is one of the very few things that work with a high degree of success.
In 1987-88 studies conducted in Europe, oleander was found to have fully six times the immune stimulating activity of the most powerful immune stimulators known to man - and I have no doubt that its ability to boost the immune system plays a very large role in it's success. However, it does far more than just boost the immune system and let the body attack cancer with its natural first line of defense. Oleander also attacks cancer itself, inducing cell death via apoptosis and autophagy and preventing cancer cells from multiplying.
Despite numerous studies, scientists still have not figured out exactly how oleander works, other than it appears obvious that it is a combination of the many different compounds found in the oleander plant. These compounds include the major active cardiac glycoside Oleandrin, a number of other cardiac glycosides such as Oleandrinogen, Oleandrigenin and others, several long-chain polysacharrides such as Beta-sistosterol, Quercitin, Linoleic-acid, Oleic-acid, Adynerin, Alpha-amyrin, Betulin, Foliandrin, Folinerin, Gitoxigenin, Isoquercitrin, Lauric-acid, Neriin, Oleandrin, Oleandrigenin, Oleanolic-acid, Rutin, Stigmasterol, Ursolic-acid, Uzarigenin.
No one knows how they work together, but those familiar with cancer and cancer research will recognize that most of these substances are stated in the literature to have antitumoral and/or immune stimulant and/or antiviral and/or antibacterial or other beneficiary activities.
I imagine that few, if any, plants in the world contain such a potent mix of immune boosters and cancer fighters - and in my mind there is no doubt that is why few, if any, plants in the world can compete with the success of oleander when it comes to cancer, HIV-AIDS, and immune boosting.
