Motherwort granules can be taken at regular intervals or when menstruation occurs. The specific time to take them should be determined by a doctor according to the patient’s condition so as not to affect the therapeutic effect or produce adverse reactions. It is mainly used to treat menstrual disorders caused by blood stasis, such as low menstrual flow, dysmenorrhea, and postpartum abdominal pain. Therefore, if you have symptoms such as low menstrual flow, dysmenorrhea, dark menstruation and blood clots, you can take this medicine to regulate menstruation under the guidance of a doctor and stop taking it when the symptoms recover. In addition, if abdominal pain and blood stasis in the uterine cavity occur after childbirth, taking this medicine can promote uterine contraction and discharge of blood stasis. However, if the patient’s irregular menstruation is caused by prolonged periods or low menstrual flow due to stagnation of Qi and blood, this can be taken before and during menstruation to help regulate menstruation. It is important to note that patients who are allergic to motherwort and those who have weak qi and blood, i.e. with pale and thin menstrual periods, dizziness and weakness, should not take this medicine before taking it. In addition, when taking motherwort granules, you should pay attention to avoid cold and spicy food, drink more warm water, avoid staying up late, and develop a good work and rest to help your body recover.
