Noting that although cupping therapy has been used in China for thousands of years, there has been no systematic summary of clinical research on the practice, investigators from Center for Evidence-Based Chinese Medicine, Beijing University of Chinese Medicine evaluated the therapeutic effect of cupping therapy using evidence-based approach based on all available clinical studies.
The authors identified 550 clinical studies, including 73 randomized controlled trials, 22 clinical controlled trials (RCTs), 373 case series, and 82 case reports. They determined that the quality of the RCTs was generally poor according to the risk of bias of the Cochrane standard for important outcome within each trials. The diseases in which cupping was commonly employed included pain conditions, herpes zoster, cough or asthma, etc. No serious adverse effects were reported in the studies.
They found that the quality and quantity of RCTs on cupping therapy appears to be improved during the past 50 years, and that the majority of studies show potential benefit on pain conditions, herpes zoster and other diseases. They recommend further rigorously designed trials to evaluate the use of cupping in clinical practice.
