Pharyngitis can usually be prevented and treated with honeysuckle tea or monk fruit tea, with good results. Generally, pharyngitis is caused by repeated acute inflammation, long-term intake of spicy foods, gastrointestinal dysfunction, and acidic irritation leading to congestion, edema, and lymph follicle proliferation in the pharyngeal mucosa and submucosal tissues. Symptoms include dry throat, sore throat, itchy throat, foreign body sensation in the throat, obstruction sensation, burning sensation, irritative cough, hoarseness, and difficulty swallowing. Severe cases may also lead to blood in the sputum. Upon examination, noticeable congestion and edema of the pharyngeal mucosa can be found, particularly in the uvula and soft palate. Lymph follicle proliferation can be seen on the posterior pharyngeal wall and pharyngeal recesses, with significant congestion in both vocal cords, though they may not close completely. For treatment, patients should first undergo symptomatic anti-inflammatory treatment. Oral administration of cephalosporin antibiotics has been found to be effective, and it should be combined with nebulized inhalation. Improvement is generally seen within about a week. (The use of medication should be conducted under the guidance of a professional doctor.)
