An oncology dietitian has warned cancer patients against using soursop tea as a treatment method, stating it 'does not work' and may cause side effects. Nichole Andrews, a dietitian specializing in cancer nutrition, addressed the topic in a recent TikTok video, urging people not to rely on the tropical fruit beverage for cancer care.
Soursop, also known as graviola, is a green fruit whose leaves are used to make a caffeine-free tea. While it is promoted for health benefits such as antibacterial properties and antioxidants, some claim it can treat cancer. However, Cancer Research UK says there is insufficient reliable evidence to support this.
Andrews responded to a viewer's question about consuming soursop while on hormone blockers for breast cancer, advising: 'Do not use soursop as any type of treatment method for cancer. It will not work. It is not even a safe choice as it can cause some side effects and issues with cancer survivors during their treatments.'
Cancer Research UK notes that lab studies have shown soursop extracts can kill some cancer cells, but these studies were not conducted on humans. The charity warns that some chemicals in the fruit may cause nerve changes and movement disorders, with symptoms similar to Parkinson's disease. They state: 'Many sites on the internet advertise and promote graviola capsules as a cancer cure. But reputable scientific cancer organisations do not support them.'
While consuming soursop in food or drink as part of a balanced diet is unlikely to pose a risk, the dietitian and charity advise patients to consult their GP before starting any complementary or alternative treatment.
