The main principle of moxibustion is to warm the menstrual cycle and promote blood circulation through the penetration of medicine and heat stimulation, which can treat various diseases caused by meridian blood or blood stasis, and also promote menstruation. If the patient’s menstruation is early within a week after moxibustion and the amount of bleeding is not too much, it is a normal fluctuation of the menstrual cycle and does not require intervention or treatment. If the menstruation is too early after moxibustion, accompanied by heavy menstruation or irregular vaginal bleeding, it is abnormal and requires a thorough medical examination to rule out other diseases, such as inflammatory diseases, tumor diseases and other organic lesions. Patients need to stop moxibustion and observe for a period of time, it will be relieved on its own and does not require treatment, so if the symptoms worsen, it needs to be treated with hemostatic drugs, such as Yunnan Baiyao or caffeic acid.
