Chinese medicine ancient book “Huang Di Nei Jing” in this way, “women seven years old, kidney gas, teeth more hair long; two seven and the deca to, Ren vein through, Taichong vein full of menstruation to time, so there is a child,…… seven seven Ren vein virtual, Taichong vein decline, the deca exhaustion, the ground is not passable, so the shape of the bad and no child. ” Women from two seven about 14 years old menarche, to seven seven 49 years old up and down menopause, generally experience 35 years of monthly cyclic menstruation, between only in pregnancy, lactation will be physiologically interrupted. Menstruation is a unique physiological feature of women and a unique health weathervane for women. The regularity of menstruation depends on the dynamic balance of yin and yang in a woman’s body. According to Chinese medicine, yin and yang are mutually rooted and utilized, and can be transformed and constrained by each other; the so-called yin pole gives birth to yang, and the yang pole turns into yin. It is in this rhythm of constant change, transformation, the formation of women’s unique menstrual period, late menstruation, ovulation, premenstrual cycle. During the menstruation period, yang flourishes and transforms into yin, and the yin blood goes down the drain. If a woman has an imbalance in her body, this sudden change can easily cause discomfort, pain, and even vomiting and diarrhea. In the late menstrual period, when yin grows and yang disappears, women are more quiet and skillful. As the qi and blood gradually fill up, the bandhas begin to increase, clear and lucid, with a dark spring. However, where there is insufficient yin and blood, the band is scanty; if internal heat is prevalent, the band is yellow and thick. To the ovulation period, the yin pole and the birth of yang, such as spring bamboo shoots quietly out of the ground, the illusion of the wonderful is the transformation of yin and yang rounded and dense. If there is insufficient qi and blood or stagnation, then stumbling, can not follow its heavenly form, will inevitably appear abnormal bleeding, ovulation pain, back pain and a series of abnormalities. Premenstrual period, Yang gradually long, qi and blood full of upward mobility, women are more impatient, body sinking and swelling. If there is internal fire, it is common to see acne on the face or front and back of the chest; liver fire upward, there are migraines, irritability; poor veins and channels are more obvious breast distension and pain difficult to touch. Until the yang pole into yin, qi and blood suddenly gathered in the uterus, menstruation again. It can be seen that the abnormalities of the menstrual cycle, quantity, color and the accompanying symptoms before and after menstruation are all caused by problems in the transformation of yin and yang. Once these conditions occur, it is important to fully realize that the body is malfunctioning, either in deficiency, excess, blockage, or imbalance, and that it needs to be adjusted and corrected in a timely manner. The treatment of Chinese medicine is to replenish the deficiencies, get rid of the excesses, smooth out the channels, balance the internal and external, the upper and lower, the left and right, so that the operation of this yin and yang inter-root and inter-use tends to be rounded and smooth, as in the yin and yang fish diagram. So a good herbal formula is not even a single soldier, but a systematized, information-based, closely coordinated, multi-targeted group army. But to prescribe such a prescription, it takes a TCM doctor a lifetime of study and practice. Western medicine treatment focuses on localized, subtle changes, and when the body’s problems are superficial and limited, this treatment is effective. However, when the situation is gradually complicated and the scope of the problem is enlarged, Western medicine can only work individually, and once the coordination and overall control is lost, it is often lost in the process. The health care of women’s menstruation is to follow the laws of nature. During menstruation, yang transforms into yin, and more rest and recuperation is needed; during ovulation, yin turns into yang, and increased exercise helps ovulation. Because of the obvious changes in these two phases, we should avoid irregularity of living and living, uncontrolled cold and heat, and unbalanced diet. Before and after the menstrual cycle, follow the growth of yin and yang, you can increase the appropriate tonic. Pre-menstrual period, Yang gradually born, appropriate to eat more warm, you can eat mutton, leeks, onions and garlic; late menstrual period, Yin gradually long, can be supplemented with chicken soup, pork ribs, eat more lilies, yams, jujubes and so on. Of course the key to tonic is moderation, not bias. When menstruation problems, according to the law of transformation of yin and yang, you can carefully look for the possible causes of the problem, and timely elimination of the cause of the disease will be able to give the body the opportunity to self-adjustment.
