濒湖脉学
The Deep Pulse (Chen) belongs to the Yin category. Its characteristic is: the fingers must press heavily down to the bones and sinews before the pulse beat can be felt. It is like cotton wrapped around sand—soft on the surface, firm within. It is also like a stone cast into water: one must sink to the bottom before touching it.
The deep pulse takes its model from Earth, bearing the imagery of a deep spring hidden beneath the ground. In the Eight Trigrams, it corresponds to the Kan trigram (☵, symbolizing water); in the four seasons, it corresponds to winter; in the human body, it corresponds to the Kidneys. Hence the deep pulse is also called the Stone Pulse, and likewise the Nutritive Pulse.
Li Shizhen specifically corrects the error of the Maijue (Pulse Canon): the Maijue states that the deep pulse "makes its slow way through the three passes, resembling rotten silk." This, in fact, describes the Weak Pulse, not the deep pulse. The deep pulse may be slow or rapid, and may appear at the cun, guan, or chi positions separately; it must not be confused with the weak pulse.
🌊 Water is moist and flows downward, and so the deep pulse descends; between bones and sinews it is soft, slippery, and even. For women, *(cun) deep⁴ in the Deep⁴? For women⁴ a deep cun pulse⁴; for men, a deep chi pulse. If this pattern persists through all four seasons, it constitutes a normal pulse (women take blood as their root, so deep cun is normal; men take qi as their root, so deep chi is normal).
One sentence distinguishes them: Deep lies among the sinews; Hidden lies upon the bone; Prison is large and forceful; Weak is fine and listless.
The deep pulse governs interior syndromes, corresponding to retained water and fluids and Yin-channel disorders. Specifically:
Indications by position:
Summary mnemonic: The deep pulse governs interior syndromes. Deep and forceful indicates interior excess; deep and foreeless indicates interior deficiency. The deep pulse chiefly indicates qi constraint and also water-damp retention. Deep and slow signifies long-standing deep cold and congealed chill; deep and rapid indicates internal heat; deep and slippery indicates food retention. Deep and sluggish indicates qi stasis with blood stasis; deep and weak indicates deficiency cold or mixed cold–heat; deep and moderate indicates cold-damp; deep and tight indicates cold-induced pain; deep and prison-like indicates cold accumulation.
The core idea of the deep pulse is the judgment of "level"—using the depth or shallowness of the pulse position to determine whether the disease site is exterior or interior.
This is an extremely important principle in Chinese medical pulse diagnostics: pulse position (superficial, middle, deep) corresponds to disease location (exterior, half-exterior-half-interior, interior). The deep pulse requires heavy pressure down to the bones and sinews before it is perceived, just as water flows downward and stones sink to the bottom. Consequently it belongs to Yin and corresponds to interior syndromes.
Here, "interior" carries two meanings:
Li Shizhen further distinguishes the pathogenesis of the deep pulse using "excess" and "deficiency":
This twofold division of "excess/deficiency" derives from the framework laid out in the Huangdi Neijing (Yellow Emperor's Inner Classic) and is concise yet profound. Forceful vs. foreeless therefore becomes the critical watershed in differentiating the deep pulse pattern: forceful indicates excess (pathogenic qi prevailing), foreeless indicates deficiency (upright qi declining).
The connection with the Kan trigram and the Kidney also deserves attention: Kan ☵ is two yin lines surrounding one yang line, outward yin and inward yang—just as the deep pulse is exteriorly soft and interiorly firm (silk-wrapped sand). The Kidney is the water viscus, governs storehouse and sealing, and in winter all things lie dormant; correspondingly, the pulse also sinks and hides within. This is a typical manifestation of traditional Chinese medicine's "correspondence between Heaven and humankind" concept—the human pulse rhythm follows natural cyclical changes, and a deeper pulse in winter is a normal physiological variation.
Aspects that can be corroborated:
The description that the deep pulse "is felt only by heavy pressing to the bones and sinews" is largely concordant with modern medicine's palpatory experience of deep arterial pulses. When cardiac output is reduced, peripheral vessels are constricted, or vessels are situated more deeply anatomically, superficial palpation cannot detect the pulse and requires deeper pressure—this corresponds logically in certain respects to the traditional Chinese medicine "deep pulse governs interior deficiency and cold." Modern studies have also observed that in conditions such as hypotension or cardiac insufficiency, the radial pulse frequently presents as deep, faint, and foreeless, which aligns with the old teaching that "deep and foreeless governs vacuity."
Aspects requiring rational consideration:
The theory that "a deep pulse at various cun, guan, and chi positions corresponds to different organ pathologies" (e.g., a deep cun indicates phlegm constraint and fluid retention in the chest, or a deep chi indicates kidney-deficient lower-origin disease) belongs to the exegetical system of Chinese medical visceral manifestation-physiology (except-organ theory). These anatomic correspondences have not been established in modern medicine. They are better understood as empirical diagnostic models rather than mechanical organ mapping. Passages such as "deep-prison governs cold accumulation" and "deep-tight governs cold pain" should be read as probabilistic distillations of accumulated clinical observation in antiquity, not one-to-one lockstep correspondences between pulse and disease. Modern Chinese medical clinicians likewise stress comprehensive unified diagnostics via the four examinations; a single pulse sign alone is never sufficient to render a diagnosis.
Follow the winter-storing rhythm 🌊: deep pulse mirrors winter and the Kidney, reminding us that during winter we should rein in mind spirit and superfluous expenditure, sleep early and rise late, allowing the body to quietly recuperate like a deep forest spring. In winter, the pulse naturally trends deeper; if one hasn't noticed one's own pulse too easily by touch, that is no cause for anxiety.

The Deep Pulse (Chen) is a Yin-class pulse. Its defining feature is that the fingers must press heavily down to the bones and sinews before the pulse beat can be felt. It resembles cotton wrapped about sand—yielding on the surface, solid within—or a stone thrown into water that must sink to the depths before it can be touched.
The deep pulse takes its pattern from Earth, carrying the image of a deep subterranean spring. In the Eight Trigrams, it corresponds to the Kan trigram (☵, emblem of water); in the four seasons, to winter; and in the human body, to the Kidney. For this reason the deep pulse is also called the Stone Pulse, and is likewise known as the Nutritive Pulse.
Li Shizhen specifically corrects a mistake in the Mai Jue (Pulse Rhymes): its statement that the deep pulse "eases its course across the three bar regions, resembling rotten silk" in fact describes the Weak Pulse, not the deep pulse. The deep pulse may be slow or rapid and may manifest at any of the three positions; it must not be equated with the weak pulse.
🌊 As water tends downward, so the deep pulse descends. Between the bones and sinews it is soft, smooth, and even. In women a deep [Cun] pulse and in men a deep [Chi] pulse, seen consistently throughout the seasons, represent a healthy presence (In women the building-bloods command, deepness at Cun being usual; in men the root qi situation yields normal depth at Chi).
One-sentence distinction locks it thus: Chen tucks outside among cuffs sinews; Hidden sprains underneath; Prison rises hefty-drilled, Worn rag submerges in rustle-bodied slight silk.
The sink governs the middle-li-bum syndrome domain — covering locked fluid/bloating, pathologies along yin-factors conduct — and works along checks:
