Irregular menstruation means that menstruation does not occur according to the normal cycle, but is more than 7 days early or late, and more than 2 consecutive menstrual cycles, also known as menstrual diffusion or irregular menstruation. Many women often suffer from irregular menstruation, which may occur once every few months, or twice a month or more, with an intermenstrual interval of less than 10 days and half a month, or simply continuously, with more or less blood than the normal period. The reason for this is that the ovaries do not have a fixed ovulation cycle, or even a long period of time without the formation of a dominant follicle, but the follicles stored in the ovaries are not static, and there are constantly developing follicles in the sinus follicles, and in batches of 5, 10, or more than 10, and growing one after another, but all unfortunately die before the formation of the dominant follicle, called follicular atresia. These small follicles, which are constantly competing for development, do not secrete sufficient amount of estrogen like the dominant follicle, but they do secrete a certain amount of estrogen to maintain the female shape and support the endometrium, which sometimes leads to continuous growth and thickening of the endometrium, but the level of this hormone lacks cyclic fluctuation and the increase or decrease is limited to half an amount, so there is no withdrawal bleeding and it can only wait until the estrogen level is insufficient to support the endometrium. If the level of estrogen is not sufficient to support the lining, it may take 2 months, 3 months, or even 6 months for breakthrough bleeding to occur before the menstrual flow is manifested. In cases where menstruation is frequent for a short period of time, endothelial rupture, exfoliation bleeding and repair occur frequently, probably because estrogen levels are between the threshold for breakthrough bleeding to occur. If the endometrium is not repaired in time or if repair and exfoliation coexist, it may cause irregular bleeding for a long time. Zhao Qisheng, Department of Gynecology, Yingkou Hospital of Traditional Chinese Medicine The main reason for such irregular menstruation is the failure of the pituitary gland to regulate the ovaries, the pituitary hormones do not effectively guide the follicular development of the ovarian cycle, and there may also be a lack of sensitivity of the ovaries to pituitary hormones. It is common in diseases closely related to female endocrine function, such as polycystic ovary syndrome, ovarian storage deficiency, hyperprolactinemia, ovarian insensitivity syndrome, and hypothyroidism. The pathogenesis, according to traditional Chinese medicine theory, is due to liver depression, spleen deficiency, and kidney deficiency resulting in Qi and blood dysregulation, disruption of the function of the flush and the accumulation of the sea of blood or the loss of the normal regularity of diarrhea. The “Essentials of Women’s Medicine” believes that “women’s blood and yin is strong and yang is sufficient, the vital energy is constant and full, the blood is strong and the menstruation is regulated, the fetus and pregnancy are easy to become; the yin and blood is full and all diseases are not born, the yin and blood is deficient and all diseases are made.” “Fu Qing master of women’s medicine” that “the menstrual water out of the kidneys, and the liver is the son of the kidney, liver depression is also depressed kidney; kidney depression will not declare the gas, before and after the or break or continue, is the kidney or pass or closed ear.” From the perspective of female menstrual physiology, Su Wen. Shanggu tianzhen zhuan” pointed out that: the woman two seven and the day sebum to, any vein through, tai chong vein Sheng, menstruation to time down, so can have children. The disorder of the Punch and Ren function is the direct cause of irregular menstruation. Both the Ren and Chong Vessels originate from the uterus (understood as the uterus in women), where the Chong Vessel is the sea of blood, which runs the part of blood that the liver harbors, and under the draining effect of the liver, it can be injected into the uterus through the uterus and the envelope in women; for the general physique, the body does not lack blood, but the channel to inject it into the uterus is no longer smooth, or understood as the Chong Vessel is not running smoothly, and the related causes can be summarized as a lack of innate endowment The causes can be summarized as a lack of congenital endowment, cold condensation, qi stagnation, phlegm, blood stasis clogging or congestion of the channels, surgical injury damaging the channels, and emotional factors causing dysregulation of liver qi, which leads to liver blood not filling the uterus regularly. As the sea of the Yin meridian, the Ren channel runs the essence of the body’s Yin fluids, including kidney essence and Tiankui, which play a regulatory role in reproductive physiology. The causes of irregularities in the Chong channel can also affect the Ren channel, and a lack of kidney essence prevents the normal infusion of Tiankui, resulting in the failure of the Ren channel’s direct regulation of the uterus and irregular menstruation. Among the many factors, congenital deficiency of endowment, deficiency of kidney qi, loss of kidney essence, congestion of phlegm, loss of drainage of liver, excessive or insufficient drainage of qi are more common, and the pathological factors interact with each other to cause disorders of the reproductive regulation axis, which is described in Chinese medicine as kidney – tiankui – punching – uterus. Professor Wang Ruoguang has pointed out that certain non-flavonoid herbs such as Cuscuta, Agaricus, Atractylodes, and Yimouzao may exert their pharmacological effects by influencing the formation of endogenous estrogen and progesterone. And these are the most commonly used drugs for treating menstrual disorders. Therefore, TCM treatment is relatively slow, even after a few menstrual cycles to see obvious results, but the follow-up effect is more durable and stable, and sometimes the effect can only be shown after stopping the medication. Treatment, whether TCM or Western medicine, is aimed at restoring the ovarian function of the ovaries. Exogenous hormone supplementation or replacement can lead to stable menstrual performance for a short period of time and sometimes have some benefit in promoting ovulation, but the long term effect is very unsatisfactory. According to the close relationship between menstruation and the liver, spleen and kidney, TCM treatment adopts a cyclical approach to regulate the liver, spleen and kidney to solve the problem from the origin of menstruation, which is relatively more accurate for restoring ovarian function, and once the endocrine regulation mechanism is improved, it helps to form a more regular ovulation cycle. A large number of clinical data confirm that herbs that regulate the liver and benefit the kidneys have a more substantial effect on improving pituitary hormone secretion, mobilizing ovarian sensitivity and balancing hormone levels in the body.
