Cough is a common symptom that can be triggered by a variety of diseases and should be treated with different anti-inflammatory and cough-relieving medications for different causes, as well as with reasonable dietary control. Cough is a common respiratory symptom, mainly caused by bacterial and viral infections, physical and chemical stimuli that damage the trachea, bronchi and mucous membranes. Coughing can discharge exudates, secretions or foreign bodies from the respiratory tract and has a protective function. A prolonged cough can also be very damaging, for example, symptoms such as chest tightness, wheezing, and difficulty in breathing can occur. Most coughs are initially caused by respiratory tract infections and can be treated with anti-inflammatory drugs for the upper respiratory tract, cephalosporins or macrolides according to the doctor’s prescription. If you have a cough with phlegm, you can take compound licorice combination and snake bile and Chuanbei cream to relieve cough and resolve phlegm. If there is very little or no phlegm, you can take codeine and cough bacillus to relieve cough. In short, besides using anti-inflammatory drugs and cough medicines, patients should also pay attention to a light diet, not to eat spicy and stimulating foods, and not to eat cold foods.
