Commentary states: Children's bodies possess wind-heat, with the Spleen and Lungs functioning poorly. Alternatively, dampness pathogen combats with the skin, causing stagnation of Qi and Blood. The skin becomes tough and thickened, transforming into various tinea (Xuan) conditions. Some are oblong, some round, gradually enlarging. Symptoms decrease slightly in cold and become itchy and stuffy in warmth; scratching yields yellow exudate. Others occur on the face, where the skin is dry and scaly like fish scales, termed "infantile tinea" (Nai Xuan). This arises from milk residue soaking the skin during nursing; washing with milk again will lead to recovery.
