《圣惠方》论述：小儿咳嗽并伴有呀呷声（形容痰气相击发出的喉间鸣响），是由于胸膈部位痰液过多，咳嗽时触动痰液上涌，阻滞于咽喉之间，痰与气息相互搏击，随着咳嗽的起伏而发出呀呷之声。其咳嗽的根本病机虽然相同，但在治疗上则需增加消痰、破除饮邪的药物，以此作为区别。

According to *Shenghui Fang*: When a child coughs and produces "ya-xia" sounds (describing the rattling noise in the throat caused by the clash between phlegm and qi), it is due to excessive phlegm in the chest and diaphragm. The act of coughing stirs the phlegm upward, where it obstructs the throat. The phlegm and qi strike against each other, producing these sounds in rhythm with the coughing. Although the fundamental pathology of the cough is the same, treatment differs by adding herbs that resolve phlegm and break down fluid retention (Yin).
