Commentary states: Pediatric sores and scabies (Jie, a skin disease characterized by itching and lesions) generally arise from the transformation of pinworms (Nai Chong), and children are prone to this ailment. It tends to occur in the interdigital spaces of hands and feet, spreading across the body. When exposed to warmth or when clothing is too thick, the child experiences unbearable itching and stifling pain, and scratching yields yellow exudate. The unceasing pain is attributed to wind-heat pathogens invading the Spleen and Lung meridians, dispersing into the muscles, and steaming the skin.
