The uterine bleeding means the excess menstrual flow of the endless discharge of menstrual blood. The former one is called overflow, and the latter one is called leakage. Although the bleeding condition of overflow and leakage is different, they are often transformable, so they are called the uterine bleeding generally. It is a common disease and a difficult disease of the gynecology, which is equivalent to the working blood of Western Medicine. It is that the abnormal bleeding of uterus caused by the endocrine disruption. Because it is examined and checked that there is no disorder of organs, it is regarded as the functional disruption, so it is called the bad uterus bleeding, and abbreviated as the working blood. At present, the Western Medicine uses the multi-purpose hormone, anti-fiber dissolving, and dilatation and curettage to treat the disease and gets certain curative effect, but it is difficult to cure it completely. If the conservative treatment is in vain and to the women who do not want to be pregnant, the uterus or the internal uterus membrane can be cut, but a lot of side effects exist. The Chinese Medicine has abundant experience and better curative effect to this disease.
