If the menstrual flow is low and dark in color, it is recommended to take Yimoucao capsules or Bazhen Yimou capsules, both of which are clinically useful for treatment. It is better to take the medicine with brown sugar and ginger water for better effect. If the symptoms do not improve after two consecutive courses of medication, it is recommended to have a clinical blood test for sex hormone six, mainly on the second or third day of menstruation on an empty stomach, and it is recommended to rest for about 10 minutes before the blood draw to avoid the test results being affected by the elevated prolactin caused by strenuous exercise. Depending on the results of the test, clinical treatment is then given accordingly. In addition, it is also important to rule out polycystic ovary syndrome clinically and to do ultrasound examination if necessary.
