《圣惠方》论述：小儿咳嗽时发出呀呷（形容痰鸣声）的声音，是因为胸膈间痰液过多，咳嗽时带动痰液上行，阻滞于咽喉之间，痰与气相互搏击，随着咳嗽的动作和气息的起伏，从而发出呀呷之声。虽然其咳嗽的根本病机相同，但在治疗上则需增加消除痰饮、破除水饮的药物，以此作为区别。

According to the *Shenghui Fang* (Sanitary Formulas of the Holy Era): When a child coughs and produces a rattling sound (ya-xia, describing the sound of phlegm), it is due to excessive phlegm in the chest and diaphragm. The coughing action drives the phlegm upward, where it obstructs between the throat and the larynx. The phlegm and Qi strike against each other, and with the movement of coughing and the rhythm of breathing, the ya-xia sound is produced. Although the fundamental nature of the cough is the same, treatment differs by adding herbs that eliminate phlegm and break down fluid retention.
