INTRODUCTION

English translation pending.

CORE DEFINITION

Nutritive qi (ying qi) is a classical concept in traditional Chinese medicine describing the qi that moves within the blood vessels. It is refined from food and drink by the spleen and stomach, nourishes the whole body, and is the material basis from which blood is generated. It is paired with defensive qi (wei qi), which circulates outside the vessels; the two are described as one internal and one external, yin and yang respectively. The concept appears in the classical literature of Chinese medicine rather than in modern physiology, and it names a functional category rather than a measurable substance.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Supply convoy: Treat vessel flow as cargo plus the energy that moves it, so weak nutritive qi means stasis and excess heat means bleeding. - Yin-yang pairing: Read any defensive or nourishing process by asking which side of the pair is currently failing. - Nourishment budget: When output drops, check whether the raw material or the transport energy is the binding constraint.

Anchor fast decisions

Blood cannot move itself. Nutritive qi is the classical name for the propulsive and nourishing component carried inside the vessels, so its condition sets the behaviour of flow: deficiency leaves blood sluggish and pooling, while excess heat drives it out of the vessels. Because it is generated from food and drink, its strength also reports on the digestive system upstream, which makes it a readout of supply and transport at once.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

When assessing a pattern, ask separately whether nutritive qi is deficient or disturbed rather than judging blood alone. 2. Look for pale complexion, faint pulse, and fatigue as signs of nutritive deficiency. 3. Match the intervention to the finding, nourishing and building when supply is short. 4. Trace persistent deficiency back to the digestive system that produces it.
