Is Acupuncture safe?
Large-scale studies of side and adverse effects in acupuncture have shown that pneumothorax and burns occur at a rate of 1 per 10,000 to 100,000 treatments, while minor adverse effects (fainting, bleeding, tiredness and pain) occur regularly (a rate of 1 per 2 to 10 treatments) (ref 14-16). When acupuncture is used for nausea and vomiting, only one needle is usually used at one point on each arm, the risk of side and adverse effects is therefore very low.
