A Cochrane Database systematic review by Australian authors, has concluded that acupuncture and acupressure may improve both physical and psychological symptoms of PMS. Five trial results, covering 277 women, were analysed. The results suggest acupuncture can improve overall mood and physical symptoms, compared with sham acupuncture. Quality of evidence was limited by small sample sizes.
