The most important health benefit of soursop tea that you will see advertised online or in stores is cancer treatment. The base tea of soursop leaves is considered by many to treat, prevent, and even cure cancer. However, at present, there is no overwhelming evidence to support these claims.
Preliminary studies suggest that soursop has both preventative and therapeutic chemo potential, but there are no conclusive results and further research is warranted.
Well-respected cancer organizations always recommend caution:
The Memorial Sloan Kettering Cancer Center acknowledges that soursop has shown anticancer properties in laboratory studies, but human data is lacking. Cancer Research UK (an England-based non-profit organization) says there is no evidence to show that soursop works as a cure for cancer.
America's Cancer Treatment Centers advise, “Experts warn against using the fruit to treat cancer. Although research suggests that soursop may fight cancer, it has not been studied in humans. As a result, there is no evidence that it is safe or effective. "
In addition to its anti-cancer properties, some people use soursop to treat infections, coughs, weight loss, herpes, inflammation of the nose and throat, and parasitic infections such as lice. Others may use graviola tea or soursop fruit to induce vomiting or to increase relaxation.
