Chronic cough is defined as a cough lasting ≥8 weeks, and its etiology is relatively complex. The 2009 Chinese Medical Association Guidelines for the Diagnosis and Treatment of Cough states, “Common etiologies include: cough variant asthma, postnasal drip syndrome, eosinophilic bronchitis, and gastric and esophageal reflux cough. These etiologies account for 70% to 95% of the causes of chronic cough in respiratory medicine outpatient clinics. Other etiologies are less common but are widely involved and are associated not only with respiratory diseases but also with diseases of other systems. Most chronic coughs are not associated with infections and do not require treatment with antibacterial drugs. Oral or intravenous glucocorticoids should be used with caution when the cause of the cough is unknown or when infection cannot be excluded”. In view of the limitations of Western medicine in treating chronic cough, traditional Chinese medicine, which has a 5,000-year heritage, has accumulated considerable experience in treating chronic cough, which is worth further exploration and promotion. Combined with my review of clinical cases of respiratory diseases in TCM over the past decade, I would like to discuss the rules of TCM treatment for chronic cough as follows: Treating chronic cough from the perspective of wind The cough mostly attacks at night and can be triggered by inhalation of cold air or exercise. The cough is triggered by inhalation of cold air or exercise. There may be a history of allergic diseases or family history, such as allergic rhinitis or eczema; laboratory tests may increase blood eosinophils or increase serum IgE, and the bronchial excitation test is positive, and anti-allergic drug therapy is effective, while cough suppressant therapy is ineffective. We have formulated our own treatment for 45 cases of cough variant asthma with satisfactory results. The clinically diagnosed cough variant asthma was randomly divided into 45 cases each in the TCM group (treatment group) and the Western medicine group (control group), and after 14 d of treatment, the symptoms were observed and the differences in clinical efficacy of the two treatments were compared. Results After statistical analysis, the total effective rate and apparent control rate of the treatment group and the control group in controlling cough and sputum symptoms.
