CORE DEFINITION

In traditional Chinese medicine, processing methods such as stir-frying, roasting, calcining, and steaming alter the medicinal properties of herbs. For example, raw Rehmannia (cold/cool, clears heat) is steamed to become prepared Rehmannia (warm/nourishing, tonifies blood).

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Parameter modifier. The same code (herb), configured with different parameters (processing methods), yields completely different functions. Don't just use fresh ginger; understand the differences between dried ginger (restores yang) and charcoal ginger (stops bleeding).

Anchor fast decisions

In traditional Chinese medicine, processing alters the medicinal properties (such as raw vs. prepared, cold vs. hot, toxicity, and channel tropism) to enhance efficacy, reduce toxicity, and facilitate preparation. This is 'processing changes nature'—the same herb, due to different processing methods, has different functional orientations.

MINIMUM ACTION

In progress 0/4

Practice this model in one real situation:

Select different processed products according to the disease pattern (e.g., raw Rehmannia cools blood, prepared Rehmannia tonifies blood
raw Pinellia is toxic, while processed Pinellia can be used)
understand the changes in the four natures and five flavors due to processing
follow standard processing procedures to reduce toxicity.
