If a woman’s menstrual period lasts about 2-3 days, but the amount of menstrual flow is between 20-60 milliliters, it is a normal physiological phenomenon. If a woman’s menstrual period is always regular and there are no other uncomfortable symptoms, it is a normal physiological phenomenon. If the amount of menstruation is less than 20 ml, it means that the amount of menstruation is low, and there is a possibility of insufficient qi and blood, uterine cold, and qi stagnation and blood stasis. If the symptoms are mild, it can be relieved by taking Motherwort capsule and Angelica sinensis blood tonic capsule orally, and also consider whether the amount of menstruation is affected by the environment, such as prolonged emotional tension, excessive work pressure, and malnutrition. If a woman’s menstrual flow is low for a long time, it may be caused by low estrogen levels in the body, low estrogen levels in the body lead to endometrial hyperplasia which is not thick enough, and if this phenomenon persists for a long time, it will have an impact on conception, so it is recommended to go to the hospital in time for treatment.
