Post-cold cough is common and usually occurs after a cold with a sore throat. The main reason is that the throat has not yet healed after an upper respiratory tract infection, and the cough is caused by the cough receptors in the air, such as dust, pollen, cold air, and irritating odors, which irritate the cough receptors in the throat after the cough receptors are exposed, and is a pharyngeal cough. Sometimes the cough is frequent and affects daily life and work. In addition to symptomatic treatment with cough suppressants, it is crucial to promote the healing of the throat. At this time, pay more attention to rest, drink more warm water, avoid eating spicy and thick food, and do not stay up late. Chinese medicine is tailored to each patient’s constitution and specific clinical manifestations. Therefore, the effect of Chinese medicine is more reliable and has fewer side effects. However, it is best to go to a regular medical institution to regulate the prescription of Chinese medicine or soup to take medicine.
