RESUMO
It's been confirmed that acupuncture-moxibustion is effective in treating primary dysmenorrhea, and the efficacy is closely related to the intervention time. By summarizing the latest research progress on real-time intervention and pre-intervention of acupuncture-moxibustion in treating primary dysmenorrhea, this articlewas to discuss about the effect of intervention time on the efficacy in treating primary dysmenorrhea and thus to provide evidence to choose the optimal intervention time. It brought up that real-time intervention of acupuncture-moxibustion can produce a significant analgesic effect in treating primary dysmenorrhea, while pre-intervention of acupuncture-moxibustion presents its advantages in generally regulating the body function. Therefore, the treatment of primary dysmenorrhea should combine real-time intervention and pre-intervention of acupuncture-moxibustion to enhance the clinical efficacy.
