People use the fruit to make juice, smoothies, ice cream, and other sweet treats.

Does SoursopTea Contain Caffeine?

Soursop tea is not a "tea" in the traditional sense and is not made from the leaves of theCamellia sinensis plant, like black tea or green tea. It is brewed using just parts of the soursop plant, which does not contain any caffeine. Therefore soursop tea is completely caffeine-free.

SoursopTea Health Benefits

Cancer treatment is the most significant soursop tea health benefit you'll see advertised online or in stores. The tea made from soursop leaves is believed by some to treat, prevent, and even cure cancer. However, right now there is no overwhelming evidence to support those claims.

Preliminary studies suggest that soursop has both chemopreventive and therapeutic potential, but there are no conclusive results and further research is warranted.

Well-respected cancer organizations still advise caution:

• Memorial Sloan Kettering Cancer Center acknowledges that Graviola has shown anticancer properties in lab studies, but human data are lacking.
• Cancer Research UK (a non-profit cancer organization based in England) states that there is no evidenceto show that Graviola works as a cure for cancer.
• The Cancer Treatment Centers of America advise, "Experts warn against using the fruit to treat cancer. While research suggests soursop can fight cancer, it has not been studied in humans. As a result, there is no evidence of its safety or efficacy."

In addition to its anticancer 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.
