A systematic review carried out in Portugal concludes that there is good scientific evidence encouraging the use of acupuncture therapy to treat anxiety disorders. Thirteen papers were selected for analysis. All studies reported a significant decrease in anxiety for the treatment group relative to the control group. Based on their analysis, the authors suggest the inclusion of the body points Neiguan P-6, Yintang, M-HN-3 and Shenmen HE-7, and the auricular points Relaxation, Tranquiliser and Master Cerebral points. Acupuncture was associated with fewer side effects than conventional treatment.
