If your menstrual blood is black and low in volume, it is recommended to take gynecological pellets and motherwort pellets to regulate your menstruation and pay attention to keeping your abdomen warm during menstruation to avoid getting cold. If you have black menstrual blood and low volume frequently, you may have endocrine disorder, polycystic ovary syndrome, anemia, etc. It is recommended to go to the hospital for endocrine examination and gynecological examination to diagnose the cause of black menstrual blood and treat it. If the endocrine and gynecological examinations are normal and the menstrual blood is black and the volume is low, it may be caused by cold in the uterus. It is recommended to drink more hot soups, especially ginger soup and brown sugar water, to help relieve the low menstrual flow and blackness. Pay attention to the warmth of the abdomen, especially the small abdomen, and avoid eating cold food to avoid aggravating the symptoms of uterine cold.
