A systematic review of complementary medical treatments, carried out by researchers at Oregon Health and Science University in the USA, has shown acupuncture can alleviate the symptoms of post-traumatic stress disorder (PTSD). They assessed 33 studies looking into the effects of various therapies on PTSD, and concluded there was good evidence for the usefulness of acupuncture, hypnotherapy, meditation and visualisation.
