The soursop otherwise know as Graviola, tree is said to have cancer fighting properties up to ten thousand times stronger in slowing the growth of cancer cells than Adriamycin a commonly used chemotherapeutic drug. Unlike chemotherapy it kills only the cancer cells and does not harm healthy cells. It is said to be effective in twelve types of cancer, including colon, breast, prostate, lung and pancreatic cancer.
The National Cancer Institute performed the first scientific research in 1976; the result showed the soursop leaves and stems were effective in attacking and destroying cancer cells. Since then the soursop leaves has proven to be a potent cancer in twenty independent laboratory tests. With all these amazing qualities one no doubt will wonder why the soursop (graviola) is not being used more in the treatment of cancer. The problem is that the soursop is completely natural and under federal law not patent-able. There is no way to make serious profits from it and that is where the roadblock comes up. One drug company invested almost seven years trying to synthesize two of the soursop’s most potent ingredients. If they could isolate and produce man-made clones of what makes the soursop so potent they would be able to patent it and make their money back. However they were unable to replicate the original.
