How should children with chronic tonsillitis be treated and cared for?

Patient's question:

Detailed medical condition and purpose of consultation: Long-term chronic tonsillitis, frequent coughing during late nights, accompanied by nasal congestion, grade II tonsillar enlargement, and nasal polyp proliferation
Duration and course of the current illness: One week
Current general condition: Same as "Detailed medical condition"
Medical history: Developed due to incomplete treatment for a cold in childhood
Previous diagnoses, treatments, and outcomes: Intermittent treatment, frequent treatment, often recurring

Doctor's answer:

Tonsillitis is generally treated by strengthening the body's constitution and immunity. Acute tonsillitis requires thorough treatment. Xuan Yan Shu Lin granules are effective for treating tonsillitis, and can be combined with Amoxicillin and others. Chronic tonsillitis is often caused by repeated infections of acute tonsillitis or poor drainage of crypts, leading to bacterial or viral infections within the crypts. In Traditional Chinese Medicine (TCM), it is known as "slow milk throat" or "deficiency fire milk throat." It is believed to be caused by incomplete treatment of wind-heat milk throat or residual heat from warm diseases, leading to lung and kidney yin deficiency and floating deficiency fire.
Clinical classification and treatment in TCM:
1. Symptoms of insufficient lung yin include: dryness and slight itching in the throat, a sensation of obstruction, occasional dry cough, swollen tonsils with surrounding redness, or accompanied by shortness of breath and fatigue.
Medications: Rehmannia, Scutellaria, Ophiopogon, Adenophora, White Peony Root, Moutan, Fritillaria, Licorice, etc.
