论述说：小儿因为气机升降失常，膈部和胃脘部气机阻滞，导致乳汁和饮水无法消化，流入胃中后，随着气机上逆而溢出，所以导致口水过多。其症状表现为胸闷、呼吸短促，饮食消化缓慢，《内经》中说脾在液为涎，应当调理脾胃，使气机升降恢复正常，那么病就可以痊愈。

These flow into the stomach and overflow upwards along with the rebellious Qi, resulting in excessive salivation (Xian). The manifestations include chest tightness, shortness of breath, and slow digestion of food. The *Neijing* states that the Spleen manifests as saliva; therefore, one should regulate the Spleen and Stomach to restore the normal ascending and descending of Qi, at which point the disease will be cured.
