What is the reason for menstruation turning black after taking traditional Chinese medicine?

Patient's question:

No

Doctor's answer:

It could be a case of cold uterus, or it might be blood stasis in the uterus. During the menstrual period, you can drink motherwort tea and pay attention to keeping warm. If necessary, go to the hospital for an ultrasound and other tests like the six sex hormone tests to confirm and treat the condition.
