Motherwort can be taken when you have your period, and it is especially recommended to start taking it on the first day of your period until it is over. Why is it good to take motherwort when I have my period? Because motherwort works to strengthen the contractions of the uterus. When motherwort is working, the uterus will contract well and menstruation will come more smoothly. Therefore, motherwort is suitable for patients with heavy and prolonged menstruation and dysmenorrhea. When the amount of menstruation exceeds three packs of ordinary toilet paper or the duration of menstruation exceeds one week, it is called excessive and prolonged menstruation. Patients who also have dysmenorrhea, if they add motherwort, will slow down the occurrence of dysmenorrhea, reduce the amount of menstruation and make it come better and more smoothly.
