Acupuncture is one of the safest medical treatments on offer in the UK, both in conventional and complementary medicine. Two independently conducted surveys published in the British Medical Journal in 2001, concluded that the risk of an adverse reaction to acupuncture is less than 1 in 10,000. A further study of 6,000 acupuncture patients in 2003, reported a handful of minor and transient side effects.
Slight bruising around acupuncture points may occur occasionally. Cupping and guasha can sometimes temporarily mark the skin, but this will usually clear in a day or two.
