This formula appears 19 times in a few articles, which shows the importance Qian Yi attached to this formula. The author summarized the application of Yihuang San in the book in order to discover the application rules of Yihuang San and eventually to guide and help clinical use. The composition of Yihuang San is Chen Pi, Clove (Mu Xiang), Chebul, Qing Pi and Licorice. The author considers that the spleen is a Yang organ, which is responsible for transportation and transformation, and if the spleen is transported, it is healthy, but if it is not transported, it is weak. Through the application of qi medicine to achieve the effect of spleen transportation, the atmosphere will turn, yang qi will arrive, essence will be dispersed, and everything will be biochemical. In the following, we will discuss the scope of application and application ideas of Yihuang San in the context of relevant articles. The scope of application of Yi Huang San 1) Deficiency of Qi in organs Yi Huang San, as its name implies, is an earthy substance that belongs to the spleen and stomach, which means it is beneficial to the spleen and stomach. Then first of all, Yi Huang San should be applied in the evidence of weakness of the spleen and stomach, and mainly in the evidence of spleen deficiency, which is also proved by the relevant articles. ”Liver disease is seen in autumn. The liver is stronger than the lung, the lung is weak and cannot overcome the liver, when the spleen and lung to treat the liver. Benefit the spleen, the mother makes the child real. For the spleen, Yi Huang San; for the liver, Di Qing Wan is the main one.” Using the theory of the five elements and the theory of phase production and phase grading, nourishing the spleen can benefit the lung, and it is also consistent with the theory of treating the untreated disease. If there is a deficiency, the mother is tonified. “Cold hands and feet from wind: the spleen is also timid, when and spleen after hair dispersal. And spleen, Yi Huang San; dispersal, Da Qing cream main.” The spleen is the master of transportation and transformation, and is the basis of the latter. The spleen is the master of the limbs, the spleen is deficient, the Yang does not transport, the Yang does not reach the four ends, so the hands and feet are cold. This is equivalent to a cold with a deficiency in the body, and if it is not dispersed, then the vital energy is even more deficient, and the deficient evil can easily enter the interior. And the spleen, Yang Qi operation, it is conducive to drive the evil out. “wound wind spontaneous benefit: the spleen deficiency timid also, when the spleen, Yi Huang San; hair dispersal, Da Qing cream main; not poor, adjust the pill main. There are lower evidence, rhubarb pills under the. After the next serving warm fright pills.” In a body with a deficient spleen, the wind and evil outside the body are obstructed by Yang Qi, and the Qi is trapped, so the food stays unchanged and the diarrhea does not stop. The same can’t be done across the board, but when the spleen deficiency is taken care of first. The main purpose of this article is to provide information about the main features of the Chinese medicine. The five elements are related to each other, and if there is deficiency, the mother should be tonified. 2) Qi disharmony The important components of Yi Huang San are all qi-regulating drugs, so it is not surprising that Yi Huang San has the effect of regulating qi. Such an article appears in the book. In fact, there is no need to cite an example, the original Yihuang San is to achieve the effect of tonifying the spleen by regulating the qi, then all the articles can be used as evidence that Yihuang San regulates the qi. ”Stomach Qi disharmony: face s white without essence, cold in the mouth, not thinking about food, vomiting water, when the spleen is tonified, Yi Huang San is the main.” Qi disharmony, transportation of the spleen is the mainstay. “Qi disharmony:frequent handfuls in the mouth, when regulating Qi, Yi Huang San is the mainstay.” 3) Yang Qi deficiency Yang Qi needs to keep running all the time, stagnant Yang Qi becomes bad Qi, which is harmful. Regulating Yang Qi can help expel external evil, and can take care of the righteous Qi and true Yin. The spleen is the essence of the latter part of the body, and the spleen is the yang earth. The spleen transports water and grain essence and regulates the qi, which all depends on yang qi. ”Summer and autumn vomiting and diarrhea: after May 15, vomiting and diarrhea, body strong heat, this heat also. Children’s internal organs, nine out of ten heat. Or due to injury heat milk food, vomiting milk does not disappear, diarrhea deep yellow, Yu Lu San main. After June 15, vomiting and diarrhea, body temperature seems hot, the internal organs of the six points of heat and four points of cold. Vomiting and vomiting, milk food does not disappear, diarrhea yellow-white, seemingly thirsty, or eat milk, or do not eat milk. Before eating less take Yihuang San, after eating more take Yulu San. After the seventh day of July, vomiting and diarrhea, the body is warm and cold, three parts hot and seven parts cold. Can not eat milk, much like sleep, smothering chaos choking gas, long out of breath, sleep dewy eyes, white lips more retching, want to stool, not thirsty. Take more Yi Huang San before eating, and less Yu Lu San after eating. After August 15, vomiting and diarrhea, the body is cold and no Yang. Cannot eat milk, dry retching, diarrhea green and brown water. When the spleen, Yi Huang San main. Do not go down also.” Adjust the use of medicine according to the changes in nature and the body’s yin and yang. Always pay attention to guarding the righteousness.” Cold deficiency of the stomach:Face s white, thin and weak, abdominal pain and lack of desire to eat. When the spleen is nourished, Yi Huang San is the main one. If downward diarrhea is present, Tune Zhong Wan is the mainstay.” Evidence of deficiency of spleen and stomach yang energy, with tonicity as the mainstay. “The stomach is shy and sweaty: up to the neck and down to the umbilicus, this is stomach deficiency. When the stomach is tonified, Yi Huang San is the mainstay.” Ideas for the application of Yi Huang San 1) The Five Elements Doctrine The Five Elements Doctrine is one of the fundamental theories of TCM, and it is an important theoretical literacy for TCM doctors to determine the treatment rules according to the law of the Five Elements and the specific situation of the patient. ”Liver disease prevails over lung: liver disease is seen in autumn. The liver is stronger than the lung, the lung is timid and cannot overcome the liver, when the spleen and lung should be supplemented to treat the liver. Benefit the spleen, the mother makes the son real. Tonic spleen, Yi Huang San; treatment of the liver, diarrhea green pill main.” The theory of the five elements, the theory of mutual vitality and mutual grammaticality, nourishing the spleen can benefit the lung, and it is also in line with the theory of treating the untreated disease. If there is a deficiency, the mother is tonified. “Day and night convulsions: due to hot flashes, Shen You not very convulsive and panting, eyes slightly oblique, the body seems hot, sleep dew eyes, cold hands and feet, stool light yellow water. It is a lung exuberance, when tonifying the spleen to treat the heart and liver. For the spleen, Yi Huang San; for the liver, Di Qing Wan; for the heart, Guo Chi San is the main one.” When the lung qi is flourishing at Shen You Xu, see convulsions at this time, when the lung is deficient, combined with wheezing, sleep dew eyes, etc. can be clear. The first one is the same as the first article, when the spleen is replenished. “Lung chancre, asthma, sores on the mouth and nose, when tonifying the spleen and lung, Yixuan San is the mainstay.” According to the theory of the five elements of symbiosis, if there is deficiency, its mother should be tonified. 2) Yin and Yang ebb and flow The doctrine of Yin and Yang is more widely applied. Yin and Yang change, creating such a colorful and changing nature; Yin and Yang ebb and flow and balance, creating the different physiques of the human body. Of course, we should consider the balance of yin and yang of nature and human body more carefully before we use medicine to remedy the deficiencies. ”Summer and autumn vomiting and diarrhea: after May 15, vomiting and diarrhea, body strong heat, this heat is also. Children’s internal organs, nine out of ten heat. Or due to injury heat milk food, vomiting milk does not disappear, diarrhea deep yellow, Yu Lu San main. After June 15, vomiting and diarrhea, body temperature seems hot, the internal organs of the six points of heat and four points of cold. Vomiting and vomiting, milk food does not disappear, diarrhea yellow-white, seemingly thirsty, or eat milk, or do not eat milk. Before eating less take Yihuang San, after eating more take Yulu San. After the seventh day of July, vomiting and diarrhea, the body is warm and cold, three parts hot and seven parts cold. Can not eat milk, much like sleep, smothering chaos choking gas, long out of breath, sleep dewy eyes, white lips more retching, want to stool, not thirsty. Take more Yi Huang San before eating, and less Yu Lu San after eating. After August 15, vomiting and diarrhea, the body is cold and no Yang. Cannot eat milk, dry retching, diarrhea green and brown water. When the spleen, Yi Huang San main. Do not go down also.” Adjust the use of medicine according to the changes in nature and the body’s yin and yang. Always pay attention to protect the righteousness. 3) The standard and the urgent are the standard and the urgent are the root. This is a familiar rule of treatment, but when it comes to the use of medicine, the standard and the urgent often make us shrink, fearing that we will lose a fraction of a centimeter and lose a thousand miles. The application of Yi Huang San may be able to give us inspiration. ”wind vomiting diarrhea body temperature: first cool and first hot, sleep more gas coarse, yellow and white stool, vomiting, milk food does not disappear, sometimes cough, more five organs and witness, when the decoction into the dirty ruler and minister of medicine, into the big green cream, after taking Yi Huang San. If the first had down, or no down evidence, careful not to down also. This is the spleen and lungs suffer from cold, can not enter the food also.” Urgent is to treat the symptoms, first dispersing the external evil, and then supporting the right qi. “wounded wind vomiting diarrhea body cold: vomiting foam, diarrhea greenish white, stuffy chaos not thirsty, choking gas, long out of breath, sleep dew eyes, this wounded wind ebony light timid, due to the vomiting diarrhea. When nourishing the spleen after dispersal. For the spleen, Yi Huang San; for dispersal, Da Qing Paste is the main one. These two evidence, more sick in the spring and winter.” In winter and spring, Yang Qi is weak and the positive Qi is insufficient, so when external evil attacks, the positive Qi is unable to resist the evil. It is important to first tonify the spleen and regulate the positive qi before dispersing the external evil. 4) The essence of the latter day In fact, all these articles are permeated with the spirit that the spleen is the essence of the latter day, and that taking care of the spleen and stomach protects the essence of the latter day. In some cases, the spleen is tonified before sweating in order to strengthen the righteousness and unite against the evil; in others, the spleen is tonified after sweating in order to restore the middle earth and not to harm the vital energy. The application of Yihuang San always reminds us that the spleen is the essence of the hind heaven, and we should consider whether the spleen and stomach are injured and when we need to protect the essence of the hind heaven while treating any disease and applying any treatment method. ”vomiting and diarrhea within the first three days of life strong heat: do not think of milk food, stool milk food does not disappear or white, is injured food. When the next, after and the stomach. Under the use of white cake sub, and stomach with Yi Huang San main.” In newborn children, the spleen and stomach are the weakest. After the injury of food, the spleen and stomach are obstructed to lift the qi, so it is important to restore the flow of qi first, and then try to strengthen the spleen and stomach to transport and transform. “The first three days or more to ten days of birth vomiting and diarrhea body warm and cold: do not think of milk food, greenish-white stool, milk food does not disappear, this is the upper real down also deficient. There are also testimonies: lungs, sleeping with dewy eyes, gasping for air. Heart, palpitations, drinking water. Spleen, drowsiness, sleepiness. Liver, yawning and boredom. Kidney, silence, fear of light. When diarrhea, see the child and the organs, spleen, Yi Huang San main. These two evidence, more sick in the autumn and summer.” In autumn and summer, summer heat and humidity are most prevalent, easily trapping Yang Qi, and the Spleen and Stomach are unable to transport and transform. The upper real and lower deficient, the upper has injured food, the lower has dirty deficiency.
