Overall Paraphrase
The wiry pulse belongs to yang-within-yin (positioned toward yang while harboring a yin quality). Its essential features are: the pulse shape is straight and long, like a drawn bowstring; upon palpation the vessel does not shift easily, and it feels broad and taut like pressing the strings of a qin se, or like zheng strings, with the finger sensing a single vessel standing straight beneath it. These descriptions derive respectively from Suwen, Maijing, and Maijue.
In analogical categorization, the wiry pulse corresponds to the Zhen trigram of the eight trigrams, the season of spring 🌿, and the liver in the human body. The normal liver pulse should be light, hollow, and slippery; if it is full and slippery like feeling a long pole, it indicates a pathological pulse; if it is taut and forceful like a newly stretched bowstring, it indicates a critical condition. Chi's consensus holds: wiry, tight, and rapid with excessive forceful tension constitutes "excess"; wiry, tight, and fine constitutes "insufficiency." Dai Tongfu held that a wiry yet soft pulse indicates mild disease, while a wiry yet hard pulse indicates severe disease.
The Maijue states "frequently accompanied by rapidity" and "the pulse is tight like a rope being pulled," but Binhu Maixue holds that these are not the true nature of the wiry pulse and omits them.
Physical Description Verse: The wiry pulse beats with a distant, straight, and long quality; when liver wood is excessive it encroaches upon spleen earth, and the person is prone to a chest full of anger, frequent desire to shout, and may develop eye opacities and persistent tearing.
Comparison Verse: The wiry pulse is straight and taut like a silk string; the tight pulse is like a rope springing left and right; "tight" emphasizes force, "wiry" emphasizes form; the firm pulse combines wiry and long qualities with deep and sunken characteristics. It is also easily confused with the long pulse.
Indications Verse: The wiry pulse corresponds to the liver and gallbladder channels of the east, and is commonly seen in phlegm-rheum (pathological products from abnormal fluid metabolism) 🌊, alternating chills and fever, and malaria. In examination, attention should be paid to floating, sunken, slow, and rapid distinctions, as well as large, small, single, and paired differences. Wiry at the inch position commonly indicates headache and abundant phlegm above the diaphragm; wiry at the left bar position indicates chills and fever or abdominal masses; wiry at the right bar position indicates stomach cold and heart-epigastric pain; wiry at the cubit position indicates yin hernia and leg cramping.
Overall, the wiry pulse is an expression of excessive wood qi. Floating and wiry primarily indicates spillage of branch rheum; sunken and wiry primarily indicates internal pain from suspended rheum; malaria frequently presents with a wiry pulse; wiry and rapid indicates heat 🔥; wiry and slow indicates cold; wiry and large indicates deficiency. Wiry and fine indicates cramping and tension; wiry at the yang (inch) position indicates headache; wiry at the yin (cubit) position indicates abdominal pain; single wiry indicates rheum accumulation; paired wiry indicates entrenched cold. If the patient cannot eat, it indicates that liver wood is excessively controlling spleen earth, which ancient physicians considered to carry a poor prognosis.
The core of the wiry pulse lies in the pulse expression of "wood qi." Traditional Chinese medicine categorizes the liver, spring, the east, and the Zhen trigram together, all sharing the characteristics of generation, expansion, and straight-flowing unruliness. Therefore, the normal wiry pulse should be "light, hollow, and slippery" — straight yet with a supple quality, reflecting the smooth flow of liver qi and adequate nourishment from stomach qi.
The key to this chapter lies in distinguishing normal pulse, excess, and insufficiency:
Conditions indicated by the wiry pulse are largely related to stagnation of liver and gallbladder qi dynamics: qi stagnation produces pain; wood excess encroaching upon earth causes the spleen and stomach to become constrained; wood depression generating fire produces alternating chills and fever; qi failing to transform water produces internal phlegm-rheum. Thus the original text attributes headache, hypochondriac pain, abdominal masses, malaria, and cramping all to the wiry pulse category. This understanding reflects the diagnostic philosophy of "inferring the internal from the external" and "five-phase generation and control" in Chinese medicine.
Modern pulse research often associates the wiry pulse with increased arterial tension, decreased vascular compliance, and elevated peripheral resistance. Under conditions such as mental tension, sympathetic excitation, blood pressure fluctuation, and atherosclerosis, the pulse indeed tends to appear "straight and long, immovable upon pressure." This overlaps empirically with the traditional Chinese medicine observations that "wiry indicates the liver" and "the liver governs emotions," suggesting that ancient physicians captured some genuine changes in vascular and circulatory states through tactile sensation.
However, this must be viewed objectively: a wiry pulse does not equal hypertension, liver disease, or any specific illness. Pulse descriptions are highly dependent on the individual clinician's tactile perception and lack unified quantitative standards; conclusions in classical texts such as "single wiry indicates rheum accumulation," "paired wiry indicates entrenched cold," and "inability to eat with wood conquering earth is difficult to treat" are empirical summaries from antiquity and cannot be directly applied as modern diagnostic or prognostic criteria. These contents should be approached rationally, without excessive mystification.
The practical guidance the wiry pulse offers for daily life centers mainly on the relationship between emotions and liver qi:
