Child has a cold and cough, now from dry cough to phlegm, should the medicine be changed?

Patient's question:

No

Doctor's answer:

Your condition may be a wind-cold cough, caused by exposure to wind-cold. This pattern is characterized by frequent coughing, thin white sputum, clear nasal discharge, pale pink tongue with thin white coating, heavy coughing sound, headache, body fever, and even shortness of breath in severe cases. It can be treated with San Yao Tang plus herbs that lower qi and resolve phlegm.
