Large Pulse / Da Mai
Updated 2026-08-04
INTRODUCTION
English translation pending.
CORE DEFINITION
A pulse quality in which the vessel feels broad and the amplitude is wide, rising strongly and fading quickly. A large pulse typically indicates exuberant qi and blood, a replete pattern, or a strong heat pathogen driving blood forcefully through dilated vessels. The crucial qualification is force: a large pulse that feels empty underneath suggests deficient yang floating upward, a hollow facade rather than genuine strength, and it calls for a very different treatment.
SCAFFOLDING EFFECT
Reduce cognitive load
- Flood model: read a wide pulse as a surge of qi and blood through the vessels. - Force check: test whether the breadth is backed by real strength or is hollow. - Contrast rule: separate genuine excess heat from floating deficient yang before treating.
Anchor fast decisions
Heat and repletion drive blood forcefully, dilating the vessel and producing a wide, surging pulse. When yang is deficient rather than excessive, it floats outward without a root, so the pulse is broad at the surface but has no substance beneath it.
