There is no evidence that hot coconut water could cure cancer.
A 2019 research stated that coconut water and vinegar reportedly possess potential anti-tumor and immunostimulatory effects. However, the anti-tumor, anti-inflammatory, and immunostimulatory effects of coconut water and vinegar are yet to be tested. Coconut water does have certain health benefits, but nowhere has it been mentioned that hot coconut water can kill cancer cells. Radiation therapy (radiotherapy) is a cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors. Around 60 percent of cancer patients go through this treatment. Dr. Rajendra Badwe, the director of Tata Memorial Hospital, said that there was no data to suggest that hot coconut water could cure any cancer.
