With the development of society and economy, the increase in pollution has been accompanied by an increase in respiratory diseases, among which the incidence of pulmonary fibrosis has also increased significantly. Why is pulmonary fibrosis and what exactly is pulmonary fibrosis? From a layman’s point of view, it means that there is more “wussy stuff” between the alveoli, and the elasticity of the alveoli is reduced accordingly. In layman’s terms, this means that there are a lot of “calluses” on or between the alveoli. The calluses, the elasticity of the alveoli, stretching or compliance of course, which will inevitably affect the respiratory function of the lungs. Reduced respiratory function, affecting the supply of oxygen, of course, a walk on the wheezing. Currently, Western medicine lacks specific treatment measures. Only relying on Chinese medicine can bring more obvious treatment results, so what exactly is the treatment from Chinese medicine? According to TCM, the basic cause of pulmonary fibrosis is phlegm stasis. Phlegm clings to the alveolar wall and stagnant blood obstructs the lung’s arteries. The interaction of the two causes pulmonary fibrosis. Therefore, taking the appropriate method of dispelling phlegm and invigorating blood to treat pulmonary fibrosis can indeed produce significant therapeutic effects. However, it is crucial to choose the appropriate blood-vitalizing drugs and expectorant drugs.
