If the menstrual flow is low and organic pathology is excluded, you can take Motherwort capsule, Eight Treasures Motherwort capsule or Gui Zhi Fu Ling capsule, all of which can effectively treat low menstrual flow. It is recommended to start taking the capsule one week before menstruation, and continue to take it until the menstruation is clean, and observe whether there is any change in the amount of menstruation. If there is an increase in the amount of menstrual flow, it is recommended to continue taking the product for three consecutive menstrual cycles in the following month. If there is no change in the amount of menstruation, it is recommended to do the following clinical examinations to find out what causes the decrease in menstruation and then give medication to treat it. First, on the 2nd-3rd day of menstruation, take a blood test for sex hormone six. Secondly, ultrasound examination should be done to find out the thickness of the endometrium, so as to exclude whether the decrease in menstrual flow is caused by incomplete adhesion of the uterine cavity, and then medication should be given in the clinic.
