《黄帝内经·素问·病能论》
人迎属于胃脉，胃气逆则跳动过盛，说明热气聚集于胃口而不得散发，所以胃脘发生痈肿。
人迎者，胃脉也，逆而盛，则热聚于胃口而不行，故胃脘为痈也。
Renging belongs to the stomach pulse, and the stomach qi will beat excessively against the stomach, indicating that the heat is concentrated in the mouth and cannot be dissipated, so the stomach and stomach become swollen.
