You can drink motherwort granules for low menstrual flow because they have the function of activating blood circulation, helping the uterus contract and promoting the discharge of stagnant blood from the uterine cavity. If a woman’s low menstrual flow is caused by poor discharge of stagnant blood from the uterine cavity, she can drink motherwort for a good therapeutic effect. There are many reasons for low menstrual flow, such as adhesions in the uterine cavity, decline of ovarian function, thin endometrium, and damage to the endometrium caused by repeated scrapings. Therefore, it is necessary to have a checkup, such as an ultrasound to understand the condition of the endometrium, a sex hormone test to understand the function of the ovaries, and a hysteroscopy to understand whether there are adhesions in the uterine cavity and inflammation of the endometrium. According to the results of the examination, the right treatment will be given, which may be much better than simply drinking motherwort pellets, so the different causes should be targeted.
