To assess the clinical efficacy of acupuncture combined with infrared light and efficacy of warming needle acupuncture for primary dysmenorrheal patients. Methods: Sixty-four patients were randomly divided into treatment group of 22 cases， warming-needle moxibustion group of 22 cases， and control group of 20 patients. From 7 days before menstruation， all patients in 3 groups were acupunctured Qihai(CV6)， Guanyuan(CV4)， Shuidao(ST28)， Guilai(ST29)， Sanyinjiao(SP6)， Diji(SP8)， once a day until onset of menstrual flow. While retaining needle， treatment group received infrared irradiation， and warming-needle moxibustion group received warming-needle moxibustion. Control group only received acupuncture. All patients were treated with 3 menstruation cycles and followed up for 3 months. Results: Overall curative effects of 3 groups were respectively 68.18% and 63.64%，and 45.00%， two treatment groups were significantly superior to that of control group(P<0.05)， and there was no statistical difference between the two treatment groups. Treat groups also showed significantly lower Vas scores， and Cox scores than that of control group (P<0.05)， and the scores were not significantly different between the two groups. Conclusion: Acupuncture combined with infrared light， and warming needle moxibustion are both effective method to treat primary dysmenorrheal. Infrared light will be more widely accepted for such advantages as user-friendliness and zero pollution.
