What should I do if the color of my menstrual blood is very dark and the flow is light each time?

Patient's question:

Age
Detailed medical condition and consultation purpose: For the past year, each menstrual period has had very dark blood, low flow, and a small amount of non-lump-like substance. I have had one painless abortion in the past and once took emergency contraception. Other than that, there are no other symptoms. Who knows any medication that can improve the color of dark menstrual blood? Please tell me the name of the medication. Thank you!

Doctor's answer:

The main reasons for a small amount of dark-colored menstrual flow are kidney deficiency, menstrual irregularity, and improper menstrual care. A small amount of dark-colored menstrual flow is considered an abnormal condition, so it is important to maintain good health practices during daily life. For example, underwear should preferably be made of cotton because it has good breathability. Additionally, women should regularly disinfect their underwear. Maintain a cheerful mood, avoid mental stress and emotional fluctuations, develop good living habits, pay attention to hygiene, and prevent bacterial infections.
Maintain a cheerful mood, avoid mental stress and emotional fluctuations. Some women may experience lower abdominal bloating, back pain, breast tenderness, mild diarrhea, fatigue, drowsiness, emotional instability, irritability, or tendency to depression during their menstrual period, which are all normal and do not require excessive concern.
Pay attention to hygiene and prevent infections. Maintain cleanliness of the external genitalia. During the menstrual period, sexual activity is absolutely forbidden. Pay attention to keeping warm and avoid cold exposure. Avoid overexertion.
Avoid eating cold, sour, spicy, or other stimulating foods. Drink plenty of warm water to keep bowel movements regular. For those with blood heat, it is recommended to consume more fresh fruits and vegetables during the premenstrual period and avoid stimulating foods like garlic, onions, leeks, and ginger. For those with poor blood and qi, it is necessary to increase nutrition regularly, such as milk, eggs, soy milk, pork liver, spinach, pork, chicken, and lamb, while avoiding cold fruits and vegetables.
For those with a small amount of menstrual flow, it is recommended to drink brown sugar water.
