Pediatric Allergic Cough
Overview
Pediatric allergic cough falls under the categories of 'cough,' 'wheezing cough,' and 'wind cough' in TCM. It commonly affects children with insufficient constitutional endowment and weakness of the lung, spleen, and kidney. The core pathogenesis is wind pathogen invading the lung with failure of lung qi to diffuse, or concurrent cold, heat, phlegm, and blood stasis; prolonged duration damages qi and yin. Clinically it presents with paroxysmal dry cough, cough triggered by throat itching, induced by wind-cold or unusual odors, worse at night and in the morning, often accompanied by nasal congestion, sneezing, and itchy eyes. Children often have insufficient lung, spleen, and kidney, insecure defensive exterior, and easy invasion by wind, leading to recurrent and lingering cough. Treatment should focus on dispersing wind, diffusing the lung, and stopping cough, while also strengthening the spleen, boosting qi, and consolidating the kidney to treat both root and branch.
Pattern differentiation (clinical patterns)
Wind Pathogen Invading the Lung
Paroxysmal dry cough triggered by throat itching, induced by wind-cold or unusual odors, worse at night and morning, nasal congestion and sneezing, pale red tongue with thin white coating, floating pulse.
Disperse wind and diffuse the lung; stop cough and benefit the throat.
Phlegm-Heat Accumulating in the Lung
Cough with thick yellow sputum difficult to expectorate, red throat and dry mouth, turbid nasal discharge, chest tightness, dry stool, red tongue with yellow greasy coating, slippery rapid pulse.
Clear heat and transform phlegm; diffuse the lung and stop cough.
Lung and Spleen Qi Deficiency
Recurrent cough with weak cough sound, thin white sputum, pale complexion, shortness of breath and spontaneous sweating, poor appetite and loose stool, susceptibility to colds, pale tongue with white coating, fine weak pulse.
Strengthen the spleen and boost qi; supplement the lung and consolidate the exterior.

Daily care & prevention
Avoid exposure to allergens such as pollen, dust mites, and pet dander; keep the living space clean and ventilated. Diet should be light and easy to digest; avoid raw and cold foods, seafood, spicy, and overly sweet foods. Adjust clothing promptly with climate changes and avoid direct wind-cold. Pediatric tuina such as clearing the lung meridian, kneading Danzhong, and pinching the spine can strengthen the constitution. Encourage moderate outdoor activity to gradually build cold tolerance. Observe cough triggers and patterns, and keep records for pattern-based care.
When to seek medical care
Seek immediate medical attention if there is persistent high fever, rapid breathing, nasal flaring, cyanosis of the lips, cough and wheezing preventing lying flat, blood-streaked sputum, listlessness or irritability, refusal to eat, or oliguria. These suggest critical condition or complications such as pneumonia or status asthmaticus. Infants with cough accompanied by choking during feeding or facial cyanosis also require emergency care.
