Pulmonary fibrosis is located in the lungs and kidneys, and the pathology of the disease is the deficiency of this standard, and the disease mechanism involves three aspects: deficiency, stagnation and toxicity. 1, false Chinese medicine believes that the body’s respiratory movement is closely related to the function of the lungs and kidneys. Lung main gas, Division of breathing, breathing is certainly the function of the lungs, in which the exhalation is by the lung’s role in declaring, inhalation is by the lung’s role in purging and lowering, but the inhalation of the descending, the need to get the kidneys to take in the role of the help, in order to be completed, how Mengyao vividly pointed out that “the gas rooted in the kidneys, but also returned to the kidneys, the kidneys take in the gas, its interest is deep” and Lin Peiqin He Mengyao vividly pointed out that “Qi is rooted in the kidneys and returns to the kidneys, so the kidneys take in qi and their breath is deep. The lungs are the masters of qi and the kidneys are the masters of qi, and when yin and yang intermingle, the breath is harmonized,” both of which indicate that respiratory movement is also dependent on the proper functioning of the kidneys. Causes have been identified or unknown pathogenic factors invade the human body, stagnant lungs, damage to the lungs, resulting in lung qi deficiency, so that the loss of gas in the main, in the internal organs for shortness of breath, wheezing, coughing, in the surface of the muscle is easy to catch a cold; lung disease deficiency, ram and kidney, the kidney qi weakness, can not return to the source of the qi, qi floating upwards, it is shortness of breath, especially when you move. Virus invasion, phlegm and stagnation cause pulmonary fibrosis. : treatment when tonifying the kidney and qi, but “long illness has been into the blood and the pungent just dry, never available”, it is appropriate to “through the blood and lubrication supplement, do not cast dry heat robbing liquid”, the treatment should be “pungent, sweet, lubrication and warm supplement”, such as Ba The treatment is suitable for “the complement of pungent, sweet, moist and warm”, such as bacopa monnieri, astragalus, parasites, zihechuan, bone-setting and other products. 2, stagnation pulmonary fibrosis is mainly due to the evil poison into the collateral and due to the lung and kidney dysfunction caused by phlegm, blood stasis and other pathological products blocked in the lung collateral, thus producing a series of pathological changes. Lung main line of water, for the water above the source, in the process of water metabolism, following the “spleen dispersal essence”, there is “through the water channel, down to the bladder,” the role of the deficiency of lung qi, the distribution of fluid and gas disorders, retention of phlegm and drink; lungs, the main section of the heart veins, towards the hundred veins, to help the heart veins and blood, if the lung qi deficiency, “the lungs,” the lungs and kidney function disorders and other pathological products blocked in the lung network, resulting in a series of pathological changes. If the Lung Qi is insufficient, “the blood in the Lung will remain”, resulting in blood stasis. Kidneys hide essence, essence of marrow, marrow blood, Yin essence deficiency, lack of source of biochemistry, or yang qi deficiency of blood running powerless, can lead to blood stasis; Kidney, water organ, the main fluid”, with evaporation of water, clear urinary functions, kidney deficiency qi no right, water stops to become phlegm and drink. As Ye Tianshi said, “after years of exhaustion, the evil retained, qi and blood are injured, septic stasis and phlegm, mixed with the meridians. Phlegm stasis obstruction is chest tightness, shortness of breath, face dark lips purple tongue purple dark, etc.; flow into the joints can form pestle finger. Pulmonary fibrosis is a long-standing disease, phlegm and stasis in the lungs in confinement, or over the years, stagnation of external evils, qi and blood are injured, which is transformed into septic blood condensation of phlegm, mixed in the meridians, is not the general herbals can be effective, and easy to dissipate the positive Qi and the evils of the disease more and more steel knot, when the Xin to pass through the channels and break the blood and expel phlegm, such as mitsubishi, curcuminoids, half-summertime, southern star of the genus. Even to fly the ascending, walking the descending, moving quickly, chasing and pulling sinking mixed qi and blood of the evil insects such as scorpions, centipedes, soft-shelled turtles, etc. in order to search for the evil picking. 3, poisonous yuan qi hair in the kidney, pass through the whole body, for the viscera meridian physiological activity of the driving force. Wei qi is rooted in the original qi, and has the function of defending against the attack of external evils. People with pulmonary fibrosis suffer from congenital deficiency of kidney qi, coupled with the use of hormones and immunosuppressants, which damages the immunity of the organism and leads to the invasion of external evils, and the evils of wind, warmth, heat, and toxicity are most common in the clinic. The combination of phlegm and stagnant phlegm in the body and the accumulation of heat will aggravate the condition, resulting in coughing, coughing up phlegm and fever. In clinical taste, patients with pulmonary fibrosis often suffer from recurrent infections in the lungs which aggravate coughing and wheezing, and even become the main cause of death. It should be actively anti-viral treatment, and many heat-clearing and detoxifying traditional Chinese medicines have strong anti-viral effects, such as Panlangen, honeysuckle, forsythia, Dazhongye, Semen zhonglian, Fritillariae chinensis, and so on, which can be chosen. In conclusion, due to the complexity of pulmonary fibrosis, both lung and kidney qi deficiency, but also evil venom retention, phlegm, stasis junction, it is difficult to use a single treatment, it is necessary to identify the disease and identify the evidence, the macroscopic and microscopic phase of the combination of Taiwan’s understanding of this disease, for the mechanism of the disease, the integration of tonifying the kidneys and natrium, phlegm and stasis, clearing the heat and detoxification of a variety of treatments in the furnace, with the evidence of additive and subtractive.
