A review of 19 randomised controlled trials covering over 3600 patients, shows acupuncture is more effective for migraine prevention than propranolol. The meta-analysis by authors at Chengdu University of Traditional Chinese Medicine, looked at trials in which acupuncture or propranolol was compared to sham acupuncture, placebo, waiting list control, or usual care. The analysis showed acupuncture had a significant advantage over the drug in reducing migraine frequency over a four week period. Acupuncture was also associated with fewer adverse events.
