Low menstrual flow and dark colour are associated with a variety of factors, such as insufficient Qi and blood, ovarian dysfunction with abnormal secretion of oestrogen and progesterone, thin endometrium and repeated induction of labour and abortion, resulting in damage to the endometrium.
If there is a deficiency of qi and blood, medication to tonify the qi and blood can be used under the guidance of a doctor.
If there is a problem with ovarian function, it is recommended that exogenous estrogen and progesterone can be supplemented to promote the growth of the endometrium.
The cause needs to be identified and targeted for symptomatic treatment.
