Interstitial pneumonia is a chronic lung disease with fibrotic changes that can cause severe lung function decline. Long-term treatment is a must, and it is important not to care about it in general and only see the doctor during acute exacerbations, because each of its exacerbations can be fatal. Although it is a very serious disease, do not give up on yourself, we start with Chinese medicine evidence-based treatment, which is still very helpful to most patients who seek treatment in time to prolong their lives and improve their quality of life as much as possible. However, Chinese medicine treatment is characterized by a holistic concept of evidence-based treatment, which focuses on systemic conditioning and staging and typing treatment, and is beneficial to the overall improvement of the disease, but in view of the individual differences of each person and the dependence of Chinese medicine on the absorption capacity of the digestive system, it requires a certain amount of time for the drug to take effect. In fact, the stage of relatively slow progress is also the best time to enter the Chinese medicine treatment. Many patients do not pay enough attention to the discovery of lesions and do not seek treatment until they are repeatedly hospitalized in acute exacerbations, often missing the best time for treatment.
