DIET · 5 MIN READ
In TCM, food is more than calories — it carries a "thermal nature" (四气: cold, cool, warm, hot). The surprising part: a food's nature is not its serving temperature. A bowl of mung-bean (green bean) soup can arrive at the table steaming hot and still be classed as cooling. What counts is how the food acts in the body, not how it feels on the tongue. For anyone prone to nasal congestion and clear, watery discharge, this distinction matters — because leaning toward warming foods is often suggested regardless of whether they are served hot or cool. Here is the plain-language version.
TCM holds that too many iced drinks, raw vegetables, and cold desserts can burden the spleen (脾) and "congeal" fluids — making the body produce more of the clear, watery mucus typical of a cold, weak pattern. This is not about bacteria; it is about how the body handles temperature.
Note: these are everyday foods, not treatments. Enjoy them as part of a balanced diet.
You do not need to eat only hot food. The point is to tilt daily habits toward warmth — especially in cool seasons and for sensitive noses. A cold drink now and then is fine; a daily habit of iced drinks is what TCM flags.
Pair this with the daily routine and the autumn guide for a fuller picture.
