CORE DEFINITION
A work by Yu Jiayan in the Ming dynasty that systematizes clinical norms and contraindications under the paired headings of method and law. Method covers the positive rules of diagnosis and treatment; law covers the prohibitions and the consequences of mistreatment that must not be violated. The key qualification is that the two are complementary: knowing only the prohibitions leaves no treatment, and knowing only the methods leaves the boundaries unguarded. The framework gives the practitioner a checkable floor while working within a dynamic diagnosis.
SCAFFOLDING EFFECT
Reduce cognitive load
- Method first: establish the treatment principle from the pattern before choosing any formula. - Prohibition check: screen the prescription against a written list of contraindications and error patterns. - Retrospective review: audit the case afterward against the rules to find omissions or boundary crossings.
Anchor fast decisions
Clinical decisions are made under time pressure and incomplete information, so a practitioner tends to follow the most salient hypothesis and stops checking. Writing the norms as explicit rules makes the check available at the moment of decision rather than only in hindsight. Because the prohibitions name specific error patterns, they catch the failure that a plausible diagnosis would otherwise carry through to prescription, which is where the harm occurs.
