Allergic disease is a specific pathological immune response in which the body’s immune system changes its protective characteristics and instead damages the organism, leading to inflammation. The general understanding is that inflammation requires antibiotics. Antibiotics are for bacterial infections, but allergic diseases are not caused by bacterial infections and do not require antibacterial drugs. Allergic inflammatory diseases have the following characteristics: 1. the initiation of inflammation or immune response is specific; 2. the early stage is dominated by the action of Th2 cells and their cytokines; 3. the course of the disease is fast and slow, but most of them are prolonged, undulating and chronic; 4. most of their outcomes are manifested as proliferative inflammation (organs are sclerotic and/or fibrotic); 5. the overall observation is done within a certain time frame, often with multi-organ pathogenesis.
