Mild moxibustion at different intervention times on the levels of ET-1 and NO in the uterine tissues of rats with cold-damp coagulation and stagnation type dysmenorrhea

The analgesic effect of mild moxibustion at different intervention times on cold-damp coagulation and stagnation type dysmenorrhea rats was different, which was the most significant in pre-instant moxibustion group. One of the mechanisms of action may be related with the adjustment of abnormal levels of ET-1 and NO.
