From Plain Questions (素问 sù wèn, zhì zhēn yào dà lùn). Expulsion through the mouth of sour fluid that flows up from the stomach. Acid vomiting is similar to acid swallowing, in which sour water flowing up from the stomach is swallowed before it is ejected, but differs in that the sour water is actually ejected. Acid vomiting is attributed to abiding food, phlegm-fire, liver fire invading the stomach, or spleen-stomach vacuity cold.
