When a woman has menstruation and her menstrual blood does not flow smoothly, the cause of the problem should be clearly identified before taking treatment measures. If it is caused by coldness in the uterus, you can take Aijian Nuan Gong Pill to warm the uterus and promote the smooth flow of menstrual blood. If it is caused by deficiency of Qi and blood, you can take medications such as Bajhen Tang and Siwu Tang to tonify Qi and blood to relieve the symptoms. If the symptoms are caused by cervical adhesions, a cervical duct dilator can be used to relieve the symptoms in mild cases, or surgery is needed to separate the cervical duct adhesions if the symptoms are more serious. If it is caused by long-term strain or mental tension, patients need to do a good job of emotional management, avoid too much tension, pay attention to proper rest, avoid staying up late for a long time, and also need to take more nutrition, eat lean meat, egg yolk and other iron-rich foods.
