Lung heat, cough and excessive sputum: Lung heat, cough and excessive sputum are caused by wind-heat evil toxins invading the lungs, or wind-cold turning into heat, the lungs being burned by heat toxins, failing to clear and descend, and phlegm-heat inside the lungs causing heat stagnation in the lungs, resulting in a symptom characterized by cough, which often occurs after a lung heat cold or without cold symptoms. Lung heat cough is often seen in children with low immunity, and the main manifestation is recurrent coughing. One of the main symptoms of lung heat cough is repeated coughing, often accompanied by chills and fever, cough and chest pain, little and sticky sputum, difficulty breathing, dry mouth and throat, and a thin yellow tongue coating.

The amount of sputum may be more or less, and it is faster to cough it out.
