Abstract: Although the lesion sites of achalasia are related to the five viscera, the main lesion relates to the lung, stomach, kidney and other organs, but based on kidney deficiency. By analyzing the lesion sites of achalasia, the main etiological mechanisms and treatment rules, this paper can provide valuable clinical treatment basis for the study of this type of disease. Keywords: kidney deficiency, kidney yin deficiency, kidney yin and yang deficiency, thirst disease is a disease caused by deficiency of congenital endowment, and due to emotional and moral disorders, poor diet and other reasons, with the basic pathogenesis of yin deficiency and dry heat, and the typical clinical manifestations of polyuria, polyphagia, polyphagia, weakness, emaciation, or sweet taste of urine. The “Rules of Evidence and Treatment? On the basis of the previous discussion, the clinical classification of the three eliminations was standardized: “Thirst and excessive drinking is the upper elimination (called diaphragmatic elimination by the Classic), elimination of grain and good hunger is the middle elimination (called elimination in the Classic), and thirst and stool with paste is the lower elimination (called kidney elimination by the Classic). The etiology and pathogenesis of kidney elimination: the pathogenesis of thirst disease mainly lies in the loss of yin and fluid, dry heat is prevalent, and the yin deficiency as the basis, dry heat as the standard, the two are mutually causal, the more deficient yin is dry heat is more prevalent, dry heat is more prevalent, the more deficient yin. The thirsty organs are mainly in the lung, stomach and kidney, especially the kidney is the key. Among the three organs, although there can be some preference, but often affect each other. Overwork, room indiscipline, loss of kidney essence, false fire, the fire because of water exhaustion and benefit, water because of the fire and benefit dry, and finally lead to kidney deficiency, lung dryness and gastric heat are present, the development of thirst. For example, the “Secret Guide to the Outer Terrace? thirst elimination” said: “excessive room labor, resulting in kidney deficiency, the lower jiao heat, heat is kidney dry, kidney dry is thirsty.” Kidney deficiency, water and fire imbalance. The kidneys are the foundation of the innate nature, the main reservoir of essence and the yin and yang. Kidney yin deficiency, the deficiency of internal fire, burnt heart and lung is thirsty drink; in burning the spleen and stomach, the stomach heat and elimination of grain; kidney loss of moistening, opening and closing of the solid regimen is not complete, the water and grain essence straight down the drain, with urine and elimination of the body, so urine more taste sweet. The kidney is also the organ of water and fire, so the imbalance of yin and yang in the kidney, water deficiency and fire dissipation, are very much related to the development of thirst disorders. As Song. Yang Shiying’s “Ren Zhai Zhi Zhi Fang. Thirst” cloud: “If water is not exhausted, there is no such thing as thirst.” The significance of the kidney in this disease is emphasized. Zhao Xianke’s “Medical Guan. Thirst”, “the vital fire is weak, can not steam and rot the water and grain, the water and grain gas, can not fumigate and moisten the lungs, such as the bottom of the kettle without salary, the lid of the pot is dry, so thirst …… strong its less fire, the bottom of the stove without salary, withered cage steam muggy, the draft harvest gets rain, the business is new…. …” This insight is a play on the doctrine of the destiny gate. When thirst is prolonged, the following two kinds of pathologies are likely to occur: first, Yin loss and Yang deficiency, and both Yin and Yang deficiency. Although thirst is based on yin deficiency and dry heat is the standard, but because of the mutual root of yin and yang, yang produces yin long, if the disease is prolonged, yin loss and yang, it will lead to the deficiency of both yin and yang. Among them, Yin and Yang deficiency of the kidney is more common. The “Jin Gui Yao Yao” has a special section on the pulse evidence and treatment of thirst, which makes up for the shortcomings of the “Inner Path” which emphasizes “thirst” rather than “elimination”. For example, “men thirst, urine, to drink a bucket, urine a bucket, the kidney pill master of.” Zhang Zhongjing also recognized the status of the kidney in the disease mechanism, emphasizing drinking a urine a kidney elimination. The established treatment of hair also mostly starts from the kidney. In particular, the provisions of the Kidney Qi Pill and its application, the pioneer of the treatment of kidney for thirst in later generations. The Kidney Qi Pill formula is based on nourishing Yin in the kidney, and benefits the true Yang with steam to rise fluid and help the upper middle and jiao, which is also useful for those who have Yin deficiency and Yang in the kidney in the late stage of severe thirst, so it has been quoted endlessly for generations. The rule of treatment of kidney elimination: for these reasons, medical practitioners of all generations have focused on kidney water. Qing. Chen Shiduo’s “Secret Records of the Stone Chamber. Thirst” clearly pointed out: “thirst evidence, although there are upper and lower, in fact, all kidney water deficiency. Medical Heart Wisdom. The Three Dissipations” says: “For upper dissipation, moisten the lungs and clear the stomach at the same time,” “For middle dissipation, clear the stomach and nourish the kidneys at the same time,” and for lower dissipation, nourish the kidneys and nourish the lungs at the same time. It can be said to have its interesting meaning. However, it should be especially pointed out that the evidence of the three eliminations all require attention to the treatment of the kidney. Qing. Chen Shiduo’s “Secret Records of the Stone Chamber. Thirst” cloud: the evidence of thirst, although divided into upper, middle and lower, but the kidney deficiency causes thirst is no different. Therefore, the treatment of thirst to treat the kidney is the main, do not need to ask its upper and lower three elimination also.” As for the treatment of the kidney, it is usually appropriate to nourish water and clear heat in cases of yin deficiency and fire; for those who have been ill for a long time, it is appropriate to also nourish the essence and fix the lower part of the body; for those who have yin deficiency and yang, and whose qi is also depleted with the evidence, and whose qi does not take in the essence, it is appropriate to also strengthen the water and benefit the qi; for some patients who have a deficiency of yang, or those who are sick in old age and whose vital fire is declining, and who have lost the ability to steam and transform, it is appropriate to also warm the yang and warm the lower part of the body, so as to raise and take in the water and qi; for those who have a floating deficiency fire, it is appropriate to also induce the fire to return to the origin. The typology and treatment of kidney deficiency:? Kidney yin deficiency symptoms: frequent urination, cloudy like grease, or sweet urine, soreness and weakness of the waist and knees, weakness, dizziness and tinnitus, dry mouth and lips, dry, itchy skin, red tongue and coating, fine pulse. Treatment: Nourishing Yin, tonifying the kidney, moistening dryness and quenching thirst.? Remedy: Liu Wei Di Huang Wan. The formula is based on rehmannia nourishing the kidney and filling the essence; shamrock nourishing the kidney and benefiting the essence, yam nourishing the spleen and nourishing the yin, fixing the essence, the dosage of the two drugs can be slightly larger in the treatment; poria strengthens the spleen and permeates dampness, zedoary and dampness, clearing the fire and heat of the liver and kidney, together nourishing the yin and tonifying the kidney, tonifying but not greasy. Yin deficiency fire and irritability, five hearts, night sweats, insomnia, can add Zhi Mu, Huang Bai nourish Yin and fire. If the urine volume is turbid, add Jiji Ren, Sangchuan, Wu Wei Zi, etc. to benefit the kidney and shrink the spring. For those with Qi and Yin deficiency with drowsiness, shortness of breath and weakness, and a light red tongue, add Radix et Rhizoma Ginseng, Radix Astragali and Rhizoma Polygonati to nourish the vital energy. Symptoms of deficiency of both yin and yang: frequent urination, cloudy like paste, even drinking a urine, emaciated face, dry ears, soreness and weakness of the waist and knees, lack of warmth in the limbs, cold fear, impotence or irregular menstruation, pale white and dry tongue coating, sunken and weak pulse. Treatment: Warming Yang and nourishing Yin, tonifying the kidneys and consolidating the body. Remedy: Jin Kui Kidney Qi Pill. In this formula, Liu Wei Di Huang Wan is used to nourish Yin and tonify the kidney, and Fructus Pulchelli and Cinnamon are used to warm the kidney yang. This formula uses both yang warming and yin nourishing herbs, as stated in Jing Yue Quan Shu? As stated in “The Eight Strategies of the New Formula”, “Those who are good at nourishing Yang must seek Yang in Yin, so that Yang will be assisted by Yin and biochemistry will be endless; those who are good at nourishing Yin must seek Yin in Yang, so that Yin will be grown by Yang and the source of water will be inexhaustible.” And “Medical Guan? thirst theory” more detailed elaboration of the application of this formula in the thirsty disease: “because the vital fire failure, can not steam rot water and grain, water and grain gas, can not be fumigated on the lungs, such as the bottom of the cauldron without pay, the pot lid dry, so thirst. As for the lungs are not endowed, can not four cloth water, parallel to the five meridians, the water it drinks, without fire, straight people bladder, is said to drink a liter of urine a liter, drink a bucket of urine a bucket, try to taste its taste, sweet and not salty can be known. Therefore, the pungent heat of the sapodilla and cinnamon is used to strengthen its less fire, add fuel to the bottom of the stove, the dry cage steams muggy, the draft grain gets rain, and the business is renewed.” For patients with thirst and Yang deficiency and fear of cold, deer antler powder 0.5g can be added as appropriate to activate the Yang and help the whole body to transform the Yang energy. For those with deficiency of both yin and yang, deer antler pills can be used to warm the kidneys, nourish yin, and replenish qi and blood. The above two formulas can be supplemented with raspberry, mulberry cuttlebone and cherry seeds to nourish the kidney and consolidate the body. Conclusion: Among the three elimination diseases, the following one is the most serious, with the center of the disease in the kidney, and the deficiency is the most frequent. Most of them are caused by old age and physical weakness, prolonged illness, weak endowment and excessive exertion. Since the lower extinction belongs to the kidney deficiency, the main focus should be to nourish the kidney, because the essence is drained with the urine, while nourishing the kidney essence, it should be combined with the method of regimen. The fire of elimination is mostly due to yin deficiency. Yin in the kidney does not help Yang. Then the fire starts in the lower, but this fire is the fire in the water, nourish its water then the fire will subside. Do not overuse bitter cold. Yin deficiency fire, dragon thunder fire floating in the upper, may also cause complications in the upper elimination, the former method with nourishing the lung and stomach agents.
