Abstract：Adenoid hypertrophy in children is one of the common diseases in otolaryngology，and its pathogenesis is closely related to damp-heat in the spleen meridian. Based on extensive clinical experience， Professor LIU Jing proposes diagnosing and treating adenoid hypertrophy in children from the perspective of damp-heat in the spleen meridian. The primary treatment principle is to clear and drain damp-heat from the spleen meridian，aiming to restore the healthy transportation and transformation functions of the spleen and stomach. In clinical practice， the principal prescription used is Xiehuang Powder，modified based on syndrome differentiation to address both the root cause and the symptoms，achieving certain therapeutic efficacy.
