Low and dark menstruation can be regulated by diet and medication. 1. Dietary modification: Low and dark menstruation may be a symptom caused by insufficient qi and blood or blood stasis from the perspective of traditional Chinese medicine (TCM). Normally, you can eat some foods that can tonify and activate blood, such as hawthorn, spinach, animal liver, red dates, black fungus, etc., which can play the role of tonifying and activating blood, and don’t eat spicy, stimulating and cold foods. 2. Medication: If menstruation is small and dark and accompanied by dysmenorrhea and other symptoms, you can take some medicines that can tonify qi and nourish blood, activate blood circulation and remove blood stasis (to promote blood circulation and eliminate blood stasis in the body) to relieve pain, such as qi and blood double tonifying pill, blood circulation capsule, and Dingkundan and other medicines. Note that those who are allergic to the above drugs are prohibited. Along with diet or medication, you should also pay attention to adjusting your mood and work routine. If the symptoms are not relieved, it is recommended to go to the hospital for consultation and standardized treatment under the guidance of physician’s diagnosis.
