There are many reasons for the low menstrual flow. It is recommended to take motherwort when you have your period because it has the effect of activating blood and removing blood stasis. Some women may have a smooth discharge of menstrual blood after taking this medicine and their menstrual flow will increase. However, some women may not be able to increase their menstrual flow even after taking motherwort. If the decrease in menstrual flow is due to ovarian hypofunction or failure, they may have to undergo alternative treatment, such as treatment with Fentanyl or Clomid, to achieve an increase in menstrual flow. Some women have had multiple abortions or scrapings, which may damage the endometrium and even lead to cervical adhesions and cervical canal adhesions, and may need to undergo cervical canal dilation or hysteroscopic separation of cervical adhesions, after which high-dose estrogen supplementation is required to slowly restore menstruation.
