Abstract: Pediatric rhinitis is a common nasal disorder in children. TCM practitioners throughout history have extensively discussed its etiology and pathogenesis. This article traces the literature and historical origins of treatment for pediatric rhinitis from the perspectives of deficiency and cold syndromes. It is pointed out that external cold is a common cause. The root cause of its recurrence is the deficiency and damage of the lungs, spleen and kidneys. The pathogenesis involves lung-qi deficiency and coldness, leading to insufficient defense of the exterior; kidney-yang deficiency results in a lack of warmth and nourishment; spleen and stomach weakness leads to the failure of ascending clear yang; all of the above factors contribute to the development of pediatric rhinitis. Additionally, the article delves into Xu's pediatrics theory of supporting yang and its application, aiming to provide assistance for clinical practice.
