CORE DEFINITION

Attributing pathological changes to disorders of Qi (function/energy) and Blood (substance/carrier), such as Qi deficiency, Qi stagnation, Blood deficiency, and Blood stasis.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Engine diagnosis. Qi is the thrust, Blood is the fuel. If the car cannot run (functional decline), is it out of fuel (Blood deficiency)? Or is the fuel line blocked (Blood stasis)? Or is the engine weak (Qi deficiency)?

Anchor fast decisions

Qi and Blood Differentiation attributes symptoms to disorders of Qi (function/energy) and Blood (substance/carrier): Qi deficiency leads to insufficient thrust, Qi stagnation to blocked passage, Blood deficiency to inadequate nourishment, and Blood stasis to halted circulation. It uses the 'power-fuel' dichotomy to locate the root cause of functional disorders.
