What are some side effects of graviola?

Graviola's side effects include potentially destroying nerve cells in the brain and other parts of the body as well as causing movement disorders comparable to Parkinson's disease, according to WebMD. The site states that women who are pregnant or breast-feeding should not use graviola.

As WebMD explains, graviola is a small evergreen tree, and its leaves, fruit and seeds are used to manufacture medicine. It is traditionally used to treat infections stemming from parasites and bacteria.

Despite safety concerns, graviola is used to treat infections caused by bacteria and parasites including herpes, coughs and cancer. People also use graviola to help them relax, and it may be applied to the skin to treat arthritis.
