Acid Regurgitation / Tun Suan
Updated 2026-08-01
INTRODUCTION
English translation pending.
CORE DEFINITION
Acid regurgitation describes sour fluid rising from the stomach to the throat and being swallowed before it can be expelled, sometimes with burning behind the breastbone. In traditional Chinese medicine it is most often attributed to liver qi invading the stomach, or to damp-heat accumulating in the stomach, and the pattern is assessed for cold or heat and for deficiency or excess before treatment. The classical therapeutic directions are to restrain the liver and support the stomach, or to clear heat and resolve dampness, rather than to suppress the acid alone.
SCAFFOLDING EFFECT
Reduce cognitive load
- Upstream Cause: look for the force pushing fluid up rather than only at the fluid - Corrosive Analogy: an irritant that leaks upward damages whatever it touches - Direction of Fix: change the pressure relationship instead of neutralising the output
Anchor fast decisions
Reflux is a pressure and direction problem, not merely an excess of acid. When normal downward movement stalls, or an outside force presses the contents upward, fluid escapes past a valve meant to hold it. Neutralising the fluid relieves the sensation but leaves the pressure imbalance intact, so the symptom returns as soon as the neutralising agent wears off, and the tissue it keeps touching stays irritated in the meantime.
