Acceptance means storage and acceptance. Kidney dominates qi, which means that the kidney has the physiological function of taking in the inhaled lungs and preventing the superficial breathing. Although the body’s breathing is controlled by the lungs, Chinese medicine believes that the normal function of breathing is also closely related to the kidneys. The specific performance is that the clear air inhaled by the lung must reach the kidney and be absorbed by the kidney, so as to maintain the smooth and deep breathing movement, so as to ensure the normal exchange of gas inside and outside the body. The breath in and out of the air, although mainly in the lungs, is rooted in the kidneys. Kidney qi is sufficient, so lung qi is inflated. Conversely, kidney qi deficiency can not help lungs inhale, and the patient will have more breathing and less breathing, and there is a feeling that inhalation cannot reach Dantian. Whether it is kidney qi deficiency, powerless intake, air levitation, chronic lung qi deficiency, chronic illness and kidney, it will cause kidney qi dysfunction, appear superficial breathing, or breathe more or less, and then move Pathological manifestations such as asthma are called & quot.kidney not gas & quot .. Kidney cough first saw “Internal Classic”. “Su Wen · Ku Lun” said: “The symptoms of kidney cough, cough is caused by pain in the lower back, and even coughing saliva.” Because the kidney hides the yin and yang, the qi and yin of the lung are derived from the kidney and its meridians Qi is connected with meridians, so the deficiency of yin and yang of the kidneys often affects the lungs, and the qi of the kidneys can dry the lungs, causing the lungs to lose their lungs and cough. People cough, not only lungs “. Explain that the occurrence of cough is not only closely related to the lungs, but also related to multiple organs. Among them, the cough caused by kidney disease and lung gold is called kidney cough. “Confucian affiliation, coughing six qi without restraining cold,” pointed out: “Cough troubles, kidney qi is also inverse.” The kidney pulse runs through the spine, the back, and the liver and spleen. “Lingshu · Bin Shun” said: “Shaoyin belongs to the kidney, and the kidney is connected to the lung.” The kidney is connected to the meridian of the lung and is closely related. In terms of function, the kidney is responsible for qi, the lungs breathe, the kidney is the basis of qi, and the lung is the main qi. When the two functions are coordinated, the breathing is normal. Because the lungs and kidneys are closely related physiologically, they must influence each other in pathology. “Yuan Guan · Cough On Treatment” pointed out: “The lungs are golden and the night lying is hidden in the kidney water. Today, because the lungs are affected by the fire of the heart, they want to avoid the water, but the kidney water is not dry, there is no fire. It is admissible to return to the disease. “Therefore, kidney disease can affect the lungs and cause coughing. From a clinical point of view, most of the occurrence of kidney cough is due to weak congenital endowment and acquired desires, such as excessive wine color, early marriage of young people, overwork, or loss of recuperation after serious illness and long-term illness, resulting in depletion of kidney essence.
