In recent years, chronic cough has become increasingly common in pediatric clinics. Parents are distraught and often feel anxious listening to their child’s bouts of coughing. So, what is chronic cough? Chronic cough in children is defined as a cough that persists for more than 4 weeks and has no specific manifestations on chest radiographs. The following types are most common: post-infectious cough, upper airway syndrome, cough variant asthma, and gastroesophageal reflux. Others may suffer from tracheal foreign bodies, cardiogenic cough, congenital lung, and tracheal anomalies. For the common types, based on many years of clinical experience, detailed identification is carried out and very good therapeutic results are achieved by using herbal medicine, while individual patients need to be treated with western medicine.
