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).
