INTRODUCTION
English translation pending.
CORE DEFINITION
A classical Chinese medicine condition, recorded in texts such as the Ling Shu, in which the extremities lose warmth and blood supply and progress to blackening, intense pain, and tissue loss. It corresponds to thromboangiitis obliterans or diabetic foot in modern terms. The core proposition is that yang qi cannot reach the periphery while cold-damp congeals in the vessels. The key constraint is that the visible necrosis is a downstream symptom, so treatment must warm yang and open the vessels rather than address the toe alone.
SCAFFOLDING EFFECT
Reduce cognitive load
- Peripheral death lens: read a dying extremity as a failed supply line from the core. - Root-versus-tip check: trace the cold, black toe back to blocked trunk vessels. - Warming strategy: restore flow to the periphery instead of treating dead tissue in place.
Anchor fast decisions
Yang qi fails to reach the extremities and cold-damp congeals the blood vessels, so the toes lose both warmth and blood. Tissue starves, blackens, and dies. The mechanism is a supply failure at the end of a distribution network: when the root loses its force, the tip withers first, which is why local treatment cannot revive it.
