The connection between the throat and the nose is medically called the nasopharynx. The presence of phlegm in the nasopharynx indicates inflammation of the mucous membrane in the nasopharynx. In the treatment, patients can take oral treatment of nasal abyss and nasal abyss oral liquid, which can effectively reduce the state of mucous membrane congestion in the nasopharynx and reduce the secretion of phlegm in the nasopharynx. At the same time, patients need to take Pu Di Lan Anti-inflammatory Oral Liquid and Eucalyptus Pinellia Enteric Soft Capsules orally, which can effectively play a role in resolving phlegm and promoting discharge. In terms of diet, patients need to pay attention to eat light liquid food as far as possible, and do not eat particularly spicy and stimulating food. After a week of treatment, the patient’s condition should improve significantly. During this period, the patient should try not to smoke or drink alcohol, and if the condition does not improve, it is best to go to the ENT department of the hospital for a detailed examination and perfect nasopharyngoscopy to clarify whether there are other lesions to avoid delaying the condition.
