If you have a chronic cough and always have yellow sputum, be careful that there may be chronic lesions in the lungs, like bronchiectasis, chronic inflammation of the lungs, or lung abscesses. When there is yellow sputum, often the lung heat is not cleared, and chronic inflammation is classified as lung heat in Chinese medicine, so it is fine to proceed with lung clearing treatment. If you want to use western medicine, but because you only cough up yellow sputum and do not have a fever, you may not have a high blood count, so it does not make much sense to use anti-inflammatory drugs, but western medicine alone with anti-inflammatory effect of phlegm medicine feels insufficient, so Chinese medicine to clear lung heat is very good to use. Chinese herbal medicine to clear lung heat also has an anti-inflammatory effect, but there is no need to do a bacterial sensitivity test, and there is no target, but only to clear the pathological basis of inflammation of the organism heat down, the condition of the organism is away from the inflammatory response. In addition, the phlegm-clearing effect of Chinese medicine is also very good, when there is yellow phlegm with lung-clearing medicine phlegm will be easier to cough out, and also not easy to trigger irritating choking cough.
