Motherwort has the effect of promoting menstruation. Motherwort has the effect of activating blood circulation and regulating menstruation, and is often used for the treatment of low menstruation due to blood stasis, irregular menstruation, and post-partum poor discharge of evil dew. Taking motherwort during menstruation can promote the discharge of blood stasis in the body and increase menstrual flow. The reason for delayed menstruation or low menstrual flow is not necessarily due to the inability of menstrual blood to be discharged, but also due to premature failure of the ovaries, the body’s low level of estrogen, which is not good for relying on motherwort to stimulate menstruation alone. Organic diseases, such as endometriosis and fibroids, can also lead to irregular menstruation. If you have irregular menstruation, you should go to the hospital for abdominal ultrasound and hormone six tests to clarify the cause of the disease and actively treat the primary disease.
