Lung heat is generally categorized as “Lung Heat, Asthma and Cough Symptoms” in Traditional Chinese Medicine (TCM), and can be treated with Diarrhea and White Powder (Dabai San) under the guidance of a physician. It is composed of Sangbai Pi, Di Bao Pi, Licorice, and Japonica Rice, which has the effect of clearing lung-heat, relieving cough and calming asthma (stopping coughing and calming wheezing). It is often used in the treatment of lung-heat asthma-cough syndrome, which is characterized by wheezing and coughing, steaming heat on the skin, especially in the cool of the day, red tongue with yellow fur, and fine pulse (the pulse becomes narrower and finer and the rate accelerates), etc. It is especially suitable for those who have positive qi. Diarrhea white powder is especially suitable for those whose vital energy has not been injured and whose fire is not very strong. Its adverse effects are not clear, and it should not be used by people with wind-cold cough or lung deficiency and asthma. If there is a need for medication, it is recommended to use the medication under the guidance of a doctor, do not use the medication on your own to avoid adverse consequences. If you feel unwell, please consult a doctor promptly.
