Binhu Maixue: Excess (Shí) Pulse

Overall Paraphrase

The Excess (Shí) pulse belongs to the yang category (with attributes of heat, excess, and movement). When taking the pulse, it can be felt whether upon light palpation (gentle pressure) or heavy palpation (firm pressure); the pulse shape is large and long, with a slightly wiry quality, presenting a full, solid, and forceful sensation beneath the fingers without any feeling of emptiness—described as "bì bì rán" (a solid, substantial appearance). This is the description from the Mai Jing (Pulse Classic). The Mai Jue (Pulse Song), however, states that the Excess pulse responds to the fingers "like a twisted rope." Li Shizhen points out that this actually describes the Tight (Jǐn) pulse, not the Excess pulse.

Body-Shape Poem (summary): The Excess pulse is large and long upon both light and heavy palpation, responding firmly and solidly without deficiency; it mostly indicates 🔥 pathogenic heat accumulating in the San Jiao (the upper, middle, and lower burners—the channels through which fluids and qi movement flow in the body), transforming into vigorous fire (hyperactive fire-pathogen). Based on this, the ancients proposed the treatment principle of "purging the bowels and inducing sweating" to provide an outlet for the pathogen, believing that only when the pathogen is eliminated can one return to safety—this is an ancient theoretical framework and should not be directly taken as specific medication guidance.

Comparison Poem (summary): The Excess pulse is full and forceful at both floating and deep levels; the Tight pulse resembles a snapping rope—taut, twisting, and unstable in nature; the Firm (Láo) pulse is deep and adheres to the space between flesh and bone; the Excess pulse is characterized by being large, slightly wiry, and relatively long in shape. Original annotation states: forceful at both floating and deep levels indicates Excess; wiry-urgent and snapping like a twisted rope indicates Tight; deep with solid, large, slightly wiry, and long qualities indicates Firm.

Disease-Indication Poem (summary): The ancients believed that diseases indicated by the Excess pulse are mostly caused by 🔥 heat and fire stagnation, manifesting as mania, delirium, and frequent vomiting; or seen in yang toxins (external febrile diseases with hyperactive heat-toxin), food stagnation from improper diet; or presenting as constipation and 💨 qi obstruction with pain. By location: Cun position (reflecting the upper jiao) Excess often shows facial heat, wind-heat disturbing the upper body, sore throat, stiff tongue, and qi rebellion with fullness in the chest; Guan position (reflecting the middle jiao) Excess often shows spleen heat and middle-jiao fullness; Chi position (reflecting the lower jiao) Excess often shows lumbar, abdominal, and intestinal pain, with difficulty in urination and defecation.

The Nei Jing (Inner Classic) states: those with excess in the blood have an Excess pulse; those with an Excess pulse often have disease from water-grain accumulation; when pulse qi arrives with excessive force, it belongs to "tài guò" (over-excess). Li Shizhen criticizes the Mai Jue: its interpretation of Chi Excess as "urinary incontinence" is exactly opposite to the Mai Jing, which states that Chi Excess indicates "lower abdominal pain and difficult urination." Later practitioners, unaware of this error, mistakenly treated Chi Excess as deficiency-cold and used warming drugs such as dried ginger and aconite—the more they treated, the worse it became. (The original phrase "何反洁" is likely a printing error, with the intended meaning being "何其反耶"—"how contradictory is this!")

🧠 Deep Understanding

Core Principles 💡

• The core of the Excess pulse is "yǒu yú" (excess/surplus). The pulse arriving forcefully at both floating and deep levels, large and long, indicates that the pathogen is vigorous while the body's righteous qi has not yet declined—a fierce struggle between righteous and pathogenic forces.
• Differentiation of three pulses: The Excess pulse is forceful at both floating and deep levels, large and long with slight wiriness; the Tight pulse is like a twisted rope—taut, urgent, and unstable; the Firm pulse is deep, solid, large, slightly wiry and long, adhering to the bones. Li Shizhen emphasizes these must not be confused.
• The Excess pulse indicates heat-fire, accumulation, and qi obstruction—excess patterns embodying the treatment principle of "excess should be drained." The original text's "purging the bowels and inducing sweating" reflects the ancient approach of giving the pathogen an outlet when heat-excess accumulates in the San Jiao; this belongs to theoretical principles, not specific prescription guidance.
• Li Shizhen's correction of the Mai Jue errors reminds us to attend to textual lineages when studying classical works and never to mistake excess patterns for deficiency-cold; otherwise, using warming and supplementation will actually fuel the heat.

Modern Understanding 🌟

• From a modern medical perspective, the full, forceful, large, and long pulse described as the Excess pulse may correlate with fever, inflammation, pain, constipation and abdominal distension, emotional agitation, and hypermetabolic states—conditions involving sympathetic excitation, increased cardiac output, and altered vascular tone.
• However, pulse diagnosis is an empirical diagnostic method from antiquity with considerable subjectivity and lacks unified quantitative standards; it cannot serve as the sole basis for disease assessment. The correspondence between the Cun-Guan-Chi positions and the internal organs should also be regarded as part of holistic pattern differentiation rather than mechanically applied.
• Li Shizhen's critique of the Mai Jue exemplifies the ancients' pursuit of truth; modern readers should likewise rely on objective examinations to clarify pathological conditions.

Health Insights ⚡

• Avoid excessive consumption of spicy, rich, greasy foods and alcohol, reducing the internal generation of accumulated heat.
• Maintain emotional equilibrium, avoiding repressed anger transforming into fire; keep bowel movements regular, exercise moderately, and maintain a consistent daily routine to promote smooth qi movement.
• If persistent high fever, agitation and restlessness, severe abdominal pain, or bowel/urinary obstruction occur, seek medical attention promptly rather than self-administering purgative, diaphoretic, or warming-tonifying methods.
