论述说：足少阴经是肾的经脉，经脉虚弱则风热邪气乘虚而入，与津液相互搏结，导致耳内生疮。世俗治疗耳疮，多用敷药、渗药或堵塞耳朵的药物，认为这样能使邪气排出体外，专门依赖外治法，却不知道通过服药来调理肾经才是更好的方法。

Discussion: The Foot-Shaoyin meridian is the meridian of the Kidney. When the meridian is deficient, wind-heat pathogenic factors invade and contend with body fluids (Jinye), resulting in sores growing inside the ear. Secular treatments for ear sores often employ topical applications, dripping agents, or ear-plugging medicines, under the belief that this expels pathogenic factors outward, relying exclusively on external therapies. Little do they know that taking oral medications to treat the Shaoyin-Kidney meridian is superior.
Decoction of Changpu for Sores Inside the Ear:
