What is the reason for dark menstrual color and reduced amount?

Patient's question:

No

Doctor's answer:

Generally, it is caused by a cold constitution. Menstrual volume is small and dark, which is a symptom of uterine cold. It is recommended that you eat less raw and cold foods, as well as cold-natured foods. Such as watermelon, pears, pork, mung beans, rock sugar, bitter gourds, etc.
