Chinese medicine can treat chronic bronchitis. Chinese medicine is an effective method for treating chronic bronchitis, but it is important to identify the evidence and the period, because chronic bronchitis is a chronic disease, which is clinically divided into acute, extended and stable periods, and the Chinese medicine treatment methods and Chinese medicine drugs are different in different periods. In the acute stage of chronic bronchitis, the patient’s physical condition and triggering factors may be different, so the treatment of chronic bronchitis with Chinese medicine should be well identified. If the patient is in the acute phase of chronic bronchitis, the symptoms, phlegm, tongue texture, tongue coating, and pulse should identify whether the cough is wind-cold, wind-heat, or wind-dry, and according to these types of evidence, treatment should be carried out using the corresponding TCM methods. If the patient enters the stable and remission phases, due to the prolonged illness, the patient will have symptoms of physical deficiency and needs to identify whether it is lung deficiency or spleen or kidney deficiency.
