Endometriosis is often manifested as dysmenorrhea, chronic pelvic pain and infertility, which seriously affects the quality of life of patients, and its incidence has been on the rise in recent years. EMS is morphologically benign, but has malignancy-like behavior such as dissemination, implantation and metastasis, and is a potential cause of infertility or chronic pelvic pain, with a prevalence of 30% to 60% among infertile women. At present, Western medicine mainly uses hormonal drugs and surgery, but it obviously inhibits the gonadal axis, with high side effects and high recurrence rate. In recent years, Chinese medicine has been used to treat EMS with significant efficacy and no significant toxic side effects. Modern Chinese medicine believes that stasis of blood is the main pathogenesis of EMS, the external invasion of the six sexes, the seven emotions, or physical deficiency, multiple births, surgical injuries, residual blood and fluid, flowing into the uterine veins, the uterine ligament, the accumulation of the lower jiao, stasis of the pelvic cavity, blood and Qi is not smooth, not pass and pain, the development of dysmenorrhea; stasis of blood, the two sperm can not be combined, the marriage is long infertility; old stasis does not go, the new blood can not return to the menstruation, the menstrual flow, prolonged periods; stasis of accumulation If the old blood stasis does not go away, the new blood cannot return to the menstrual flow, resulting in heavy menstruation and prolonged menstruation. Therefore, internal accumulation of blood stasis becomes the most important pathological basis of the disease. In clinical practice, according to the four diagnostic examinations, it can be classified into Qi stagnation and blood stasis, cold stagnation and blood stasis, heat stagnation and blood stasis, and kidney deficiency and blood stasis. Therefore, the basic treatment in TCM is to activate blood circulation and eliminate blood stasis, taking into account either regulating qi, dispersing cold, clearing heat, or tonifying the kidney. The formula is based on the combination of Blood Mansions and Stasis Soup, Shao Belly and Stasis Soup, Heat Clearing and Blood Regulating Soup, and Kidney Returning Pill (Jing Yue Quan Shu) with Peach and Red Four Wonders Soup. Endometriosis is a clinically difficult disease, at present, most of our treatment methods are as follows: 1, after the identification and treatment of Chinese medicine, the use of Chinese medicine oral treatment; 2, in the case of unsatisfactory results of Chinese medicine oral treatment, can use Chinese medicine comprehensive treatment, Chinese medicine oral with Chinese medicine decoction every night retain enema, abdominal or vaginal microwave therapy, or acupuncture treatment, etc. often get better results; 3, the combination of Chinese and Western medicine treatment. EMS is a hormone-dependent disease, and hormone therapy is often used for more than 3 months or half a year, which has a lot of side effects, amenorrhea and perimenopausal syndrome, and the relapse rate is also high after stopping the drug. If hormones are used to suppress ovulation, at the same time, Chinese herbal medicines are given to activate blood circulation and remove blood stasis, soften and disperse the nodules, which can promote rapid atrophy and degeneration of ectopic endometrium and the absorption and dissipation of nodules, and then combined with identification and staging treatment, it can eliminate dysmenorrhea and regulate menstruation to help pregnancy. This method can reduce the amount of hormone use and shorten the course of treatment, and the Chinese herbs have no obvious side effects, can be taken for a longer period of time, and can be used for pregnancy during treatment, which is easily accepted by patients. Chinese medicine treatment for EMS, oral, external treatment, acupuncture and moxibustion as well as comprehensive therapy all have their own characteristics, and Chinese medicine drug formulations and routes of administration are diversified, with significant efficacy and no obvious toxic side effects. Preventive effect of Chinese medicine on endometriosis: The increase of surgeries such as curettage, cesarean section, abortion and intrauterine device has increased the absolute incidence of EMS. Therefore, the preventive treatment of patients after various surgeries with Chinese medicine can promote the discharge of intrauterine blood stasis and prevent backflow, as well as reduce the stress response to surgery and regulate the neuroendocrine and immune functions of the body, thus reducing the incidence of the disease. Similarly, for EMS patients who have undergone surgical treatment, if Chinese herbal medicine is given immediately after surgery, or if Chinese herbal medicine is combined with a little hormone treatment, it can play a pivotal role in controlling the recurrence of this disease.
