The appearance of yellow phlegm in the throat is not a sign of fire, which is only a symptom expression in Chinese medicine. The inflammatory cells in the body will gather in the throat and swallow or fight with foreign bacteria, and these cells will lyse and necrotize and also secrete. These cells and secretions mix together to form yellow sputum, which is mainly due to bacterial infection, so taking antibiotics is the most important treatment. For upper respiratory tract infection, cefradin, cefaclor, cefadroxil, and cefadroxil can be taken for treatment; if the throat is sore, Pudilan anti-inflammatory oral solution can also be taken at the same time; for more serious cases of yellow sputum, lung power cough combination and fresh bamboo liquid can be taken for treatment at the same time.
