INTRODUCTION

English translation pending.

CORE DEFINITION

A doctrine from the Huangdi Neijing stating that the four qi, warm, hot, cool and cold, belong to yang or yin, as do the five flavours, pungent, sweet, bland, sour, bitter and salty. Qi is treated as the energetic aspect and flavour as the material aspect, with thick qi being yang and thick flavour being yin. The proposition is that these two coordinates predict the direction of a drug's action: pungent and warm rises and disperses, while bitter and cold descends and drains. The qualification is that the reading is relative, so combination matters more than any single property.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Periodic table of drugs: classify an agent by qi and flavour instead of by name. - Direction finder: use the pair to predict whether an action rises, disperses, descends or drains. - Combination logic: read how two agents' charges combine before expecting a given effect.

Anchor fast decisions

Qi and flavour describe two independent properties, energy and substance, so together they locate an agent on a two-axis map. Because direction of action follows from that location, the same map explains why one drug lifts a pathogen to the surface while another drives it downward, and it lets an unfamiliar substance be placed before it is ever used.
