What is pulmonary fibrosis? Pulmonary fibrosis is the end-stage change of a large group of lung diseases characterized by proliferation of fibroblasts and a large number of extracellular matrix aggregates with inflammatory damage and tissue structure destruction, that is, normal alveolar tissue is damaged after abnormal repair leading to structural abnormalities (scar formation). Pulmonary fibrosis treatment: Patients with pulmonary fibrosis are often treated with hormone therapy by western medicine, which should be combined with traditional Chinese medicine at the same time as hormone therapy. If western medical treatment is not effective, Chinese medicine becomes the primary choice for treating pulmonary fibrosis patients. However, it is important to note that Chinese medicine should be taken in a regular medical institution. Chinese medicine practitioners need to treat the patient according to the evidence and use the medicine according to the patient’s condition, and it is best to choose Chinese medicine soup treatment, but of course, when stable, it can be combined with pills.
