A Cochrane Database systematic review has concluded that moxibustion may help to reduce the haematological and gastrointestinal toxicity of chemotherapy or radiotherapy, and thereby improve the quality of life in people receiving cancer treatment. Twenty-nine RCTs involving 2569 participants met the Chinese authors inclusion criteria. They found beneficial effects of moxibustion on increasing blood cells and promoting immunological function, decreasing gastrointestinal symptoms caused by toxicity of chemotherapy or radiotherapy (such as nausea and vomiting), and improving quality of life. However, poor reporting and high risk of bias in study methods reduced the certainty of the evidence.
