南宋崔嘉彦（紫虚真人）撰，又名《紫虚脉诀》《崔氏脉诀》，李杲等曾校评。以《难经》浮、沉、迟、数四脉为宗，风气冷热四气主病；四言歌诀述荣卫、脉理、部位、病脉。要点：脉本荣卫，荣行脉中、卫行脉外，气动脉应；浮无力为芤、沉有力为实、迟数分冷热虚实。提纲挈领，便诵便记，是道医与金元医学交界的入门脉学，后潘楫等有详解。
⚡ Ứng dụng: 先背四言总诀，以浮沉迟数统摄诸脉，再进《濒湖脉学》《医道还元》脉理奥旨深化。

The pulse classic proves that the body reports its five-phase status in a readable, hierarchical language of pulse qualities; diagnosis is lawful inference from tactile signs to pattern, not guesswork. By versifying pulse lore, it argues that clinical judgment must be memorizable, portable, and pattern-based under time pressure. The physician’s hand becomes a logic engine linking symptom surface to root imbalance.
1) Correlate BaZi seasonal strength with expected pulse tendencies across the year. 2) When chart and pulse disagree, privilege present-body evidence for immediate care. 3) Use pulse-change to verify whether luck-year advice is physiologically landing. 4) Train few primary pulse patterns tied to common BaZi imbalances. 5) Integrate pulse checks before aggressive cultivation increases.
Unlike Daoist 心印/玉枢 scriptures, this is clinical semiotics of the body, not liturgical or alchemical metaphysics. Unlike 千金翼方’s broad formulary scope, 崔真人脉诀 is a diagnostic logic core—how to know—before what to prescribe.
