Bronchial asthma, a chronic inflammatory disease of the airways involving a variety of inflammatory cells such as eosinophils, mast cells and T lymphocytes. It manifests clinically as recurrent episodes of wheezing, dyspnea, chest tightness or coughing, often occurring at night and/or early in the morning and intensifying, often with widespread and variable irreversible airflow limitation, which can be relieved by most patients on their own or with treatment. It has a high mortality rate and seriously endangers patients’ health, and belongs to the category of “croup and asthma” in Chinese medicine. In China, most of the western medical treatments are hormonal drugs, β2 agonists and theophylline drugs, but the toxic side effects are great.
