Coughing at night can be caused by either lung heat or lung cold, which needs to be analyzed in conjunction with other clinical symptoms. If the cough is caused by lung heat, there will be yellow sticky sputum and phlegm, yellow and thick tongue coating, accompanied by nasal congestion, sore throat and other symptoms; if the cough is caused by lung cold, there will be coughing up white, thin sputum, white tongue coating, and so on. If the cough is caused by heat in the lungs, you can take Fresh Bamboo Liquid under the guidance of a doctor, which has the effect of clearing away heat and resolving phlegm to stop coughing. If the cough is caused by lung cold, you can take Xiao Qing Long Granules or Tong Xuan Li Lung Pills under the guidance of a doctor. Xiao Qing Long Granules can relieve cough and calm asthma (stopping cough and calming wheezing), while Tong Xuan Li Lung Pills can relieve cough, resolve phlegm, and relieve cough by clearing away heat and removing phlegm. Regardless of whether the lungs are hot or cold, it is important to follow the doctor’s instructions to use the medication correctly.
