The pulse is the channel through which blood flows, and it is the precursor of qi and blood movement. The pathway of blood responds in harmony with the breath.
The pulse pattern takes its model from the earth; it is the reservoir where blood gathers, united with the heart, and distributed throughout the various layers of the skin.
The resource of the pulse originates from the Kidney (the foundation of prenatal essence) and is nourished by the Stomach (the foundation of postnatal essence). The pulse belongs to yang within yin (the yin aspect within yang), and its root lies in nutritive and defensive qi (nutritive being the nourishing blood, defensive being the protective qi). Nutritive belongs to yin blood; defensive belongs to yang qi. Nutritive moves within the vessels; defensive moves outside the vessels.
The pulse does not move by itself; it beats in accordance with the movement of qi. When qi moves, the pulse responds, manifesting the principle of yin-yang interaction. Qi is like the bellows driving the wind, blood is like rising and falling waves; blood and breath circulate ceaselessly upward and downward within the body.
Among the twelve regular meridians (the twelve main channels of the human body), all have arterial pulsation, but only the Cunkou (radial artery at the wrist) of the Hand-Taiyin Lung Meridian is selected as the standard position for pulse diagnosis. This is because this meridian belongs to the Lung, connects upward to the throat, and is the gathering place of pulse qi, where inhalation and exhalation correspond to it.
One inhalation and one exhalation constitute one breath-cycle; four beats per breath-cycle is normal. In one day and night, there are approximately 13,500 breath-cycles. With each breath, the pulse qi travels six cun, and in one full day and night, it travels a total of 810 zhang.
When first examining the pulse, have the patient extend the palm upward. The high bone behind the palm (styloid process of the radius) is called Guan. Before Guan is yang; after Guan is yin. The yang position is Cun, the yin position is Chi, and one examines them in sequence.
The Heart and Liver correspond to the left-hand pulse; the Lung and Spleen correspond to the right-hand pulse. The Kidney and Mingmen (right kidney, governing ministerial fire) correspond to the two Chi positions. The soul, spirit, grain, and spirit (mental and digestive functions) can all be examined at Cunkou. The left hand governs the (hollow) organs, the right hand governs the (solid) organs. A left pulse that is relatively large favors males; a right pulse that is relatively large favors females. Regarding the support of the life pulse, males take the left as primary, females take the right as primary.
One-tenth of a cun before Guan is the master of life; on the left it is called Renying, on the right it is called Qikou. Shenmen (the region behind the Chi pulse) is examined behind both Guan positions. If both places have no pulse, then the illness is severe and difficult to cure.
The pulse in males and females is basically the same; only the Chi pulse differs. In males, weak yang and abundant yin (weak Cun and full Chi) is normal; the reverse indicates the arrival of disease.
The pulse has seven examinations: floating, middle, deep, upper, lower, left, and right, which require careful investigation. There are also nine considerations: gentle palpation and heavy pressure; the three sections each divide into floating, middle, and deep, with each section observing five beats.
Cun examines above the chest; Guan examines below the diaphragm; Chi examines from below the navel down to the heel. The left pulse examines the left side; the right pulse examines the right side. Wherever the disease is located, the corresponding pulse position will show abnormality; where there is no disease, there is no abnormality.
The floating pulse governs the Heart and Lung; the deep pulse governs the Kidney and Liver. The Spleen and Stomach reside in the middle burner, with the pulse between floating and deep.
The floating pulse of the Heart: floating, large, and scattered. The floating pulse of the Lung: floating, rough, and short. The deep pulse of the Liver: deep, wiry, and long. The deep pulse of the Kidney: deep, firm, and soft.
The Spleen and Stomach belong to Earth; the pulse should be calm and harmonious. Mingmen is ministerial fire, judged together with the left Cun.
In spring the pulse is wiry; in summer it is bounding; in autumn it is fuzzy (as light as a feather); in winter it is stony (deep and firm); at the end of the four seasons it should be calm and moderate. When disease arises internally, an pulse pattern that violates the four seasons is inauspicious. If the spring pulse appears as an autumn pulse, it means Metal overcomes Wood, and death occurs on the day when Metal prevails. The five organs can be inferred in the same manner to predict prognosis.
For all the hundred diseases of the four seasons, stomach qi is the foundation. The pulse values having spirit—this must be carefully examined.
Regulate the breath evenly; four to five beats per breath-cycle is the standard of balance. Three beats per breath-cycle is a slow pulse, and slowness indicates cold. Six beats per breath-cycle is a rapid pulse, and rapidity indicates heat. The slower, the colder; the faster, the hotter. Once slow and rapid are understood, one must also distinguish floating and deep.
The floating, deep, slow, and rapid pulses can distinguish internal and external causes. External causes come from Heaven and Earth (the six excesses); internal causes come from the person themselves (the seven emotions). Heaven has yin, yang, wind, rain, darkness, and obscurity; humans have joy, anger, worry, thought, grief, fear, and fright.
A floating pulse due to external causes indicates exterior syndrome. Deep indicates interior, slow indicates yin, rapid indicates exuberant yang. A floating pulse due to internal causes is brought about by deficient wind. Deep indicates qi stagnation, slow indicates cold, and rapid indicates heat without doubt.
Floating and rapid indicates exterior heat; deep and rapid indicates interior heat. Floating and slow indicates exterior deficiency; deep and slow indicates cold accumulation. Exterior–interior, yin–yang, wind–qi–cold–heat: distinguish internal and external causes, with pulse and syndrome mutually referenced.
The principles of the pulse are vast and numerous, but they can be summarized into the four outlines of floating, deep, slow, and rapid. Once one grasps the outline, one can extend and apply it analogously.
The floating pulse takes its model from Heaven; it can be obtained with a light hand, floating broadly above, like wood drifting on water. Floating and forceful, large and bounding, coming strong and receding weak, is the bounding pulse. Without force, large, vacuous, and soft, is the vacuous pulse. When vacuity is extreme, it becomes scattered and diffuse without convergence—the scattered pulse. Having edges but no center is the hollow pulse (like pressing a scallion stalk). Floating and small is the soft pulse, like silk floating on water. When softness becomes extreme, it is faint and difficult to locate—the faint pulse.
The deep pulse takes its model from Earth, close to sinew and bone, sinking to the lower regions. When deep reaches its extreme, it becomes the hidden pulse. Deep and forceful is the firm pulse, solid, large, wiry, and long. When firmness becomes extreme, it becomes the replete pulse, full and hard. Deep and without force is the weak pulse, soft and small like cotton. When weakness becomes extreme, it becomes the thin pulse, as fine as a spider's thread.
The slow pulse belongs to yin, with three beats per breath-cycle. Slightly faster than slow is the moderate pulse, not quite reaching four beats. Two beats per breath-cycle is the wasting pulse; one beat per breath-cycle is the defeating pulse, where the disease cannot be treated. One beat every two breath-cycles is called loss of essence, where the pulse has already lost qi.
Floating, large, vacuous, and scattered, or appearing as hollow or leather; floating and small as soft or faint; deep and small as thin or weak. Slow and thin is the rough pulse, moving with difficulty, easily pausing, and returning after stopping. The knotted pulse comes slowly, stops, and then resumes. The intermittent pulse comes slowly, stops, and cannot return.
The rapid pulse belongs to yang, with six beats per breath-cycle. Seven beats per breath-cycle is hurried, eight is extreme, nine is exhausted. Floating and large is bounding; deep and large is firm or replete. Moving freely and smoothly is the slippery pulse. Forceful is the tight pulse, springing against the finger like a twisted rope. Rapid appearing at Cunkou with pauses is the running pulse. Rapid appearing at the Guan section, the moving pulse can be observed—restless and shaking, shaped like a small bean.
The long pulse indicates smooth flow of qi, extending beyond its normal position. Long, straight, and upright, like pressing a zither string, is the wiry pulse. The short pulse indicates qi disease, not reaching its full position; it does not appear at Guan but only at Cun and Chi.
Each pulse has its form, and each governs its own disease. When several pulse patterns combine, they manifest various syndromes.
Floating pulse governs exterior conditions; the interior must be deficient. Forceful indicates wind-heat; without force indicates blood weakness. Floating and slow indicates wind deficiency; floating and rapid indicates wind-heat. Floating and tight indicates wind-cold; floating and moderate indicates wind-dampness. Floating and vacuous indicates heat-stroke injury; floating and hollow indicates blood loss. Floating and bounding indicates deficient fire; floating and faint indicates extreme exhaustion. Floating and soft indicates yin deficiency; floating and scattered indicates severe deficiency. Floating and wiry indicates phlegm-rheum; floating and slippery indicates phlegm-heat.
Deep pulse governs interior conditions, governing cold and accumulation. Forceful indicates phlegm-food; without force indicates qi stagnation. Deep and slow indicates deficient cold; deep and rapid indicates hidden heat. Deep and tight indicates cold pain; deep and moderate indicates water retention. Deep and firm indicates chronic cold; deep and replete indicates extreme heat. Deep and weak indicates yin deficiency; deep and thin indicates bi-dampness. Deep and wiry indicates rheum pain; deep and slippery indicates retained food. Deep and hidden indicates vomiting and diarrhea, yin toxin accumulation.
Slow pulse governs the solid organs, where yang qi lies hidden. Forceful indicates pain; without force indicates deficient cold.
Rapid pulse governs the hollow organs, governing vomiting and mania. Forceful indicates heat; without force indicates sores.
Slippery pulse governs phlegm, or injury from food. In the lower position it governs blood accumulation; in the upper position it governs vomiting and counterflow.
Rough pulse governs scarcity of blood, or dampness-cold in the middle. It governs vomiting of stomach reflux, bound intestines, spontaneous sweating, and reversal cold of the extremities.
Wiry pulse governs rheum, with the disease belonging to the Gallbladder and Liver. Wiry and rapid tends toward heat; wiry and slow tends toward cold. Floating and wiry governs hypochondriac rheum; deep and wiry governs suspended pain. Yang wiry governs headache; yin wiry governs abdominal pain.
Tight pulse governs cold, and also governs various pains. Floating and tight governs exterior cold; deep and tight governs interior pain.
Long pulse governs balanced qi; short pulse governs qi disease. Thin governs qi deficiency; large governs progression of disease. Floating and long governs wind-epilepsy; deep and short governs retained food. When blood is deficient, the pulse is vacuous; when qi is replete, the pulse is replete.
Bounding pulse governs heat, with yin being deficient. Thin pulse governs dampness, with blood being deficient. Moderate and large governs wind; moderate and thin governs dampness. Moderate and rough governs blood deficiency; moderate and slippery governs internal heat.
Soft and small governs yin deficiency; weak and small governs yang exhaustion. When yang is exhausted, there is aversion to cold; when yin is deficient, there is fever. When yang is faint, there is aversion to cold; when yin is faint, there is fever. In males, faintness governs deficiency-consumption; in females, faintness governs discharge of blood.
Yang moving governs sweating; yin moving governs fever, governing pain and fright, and governing uterine bleeding.
Deficient cold contending together is named the leather pulse. In males it governs seminal loss; in females it governs blood loss.
Yang exuberance produces running pulse, governing lung abscess and yang toxin. Yin exuberance produces knotted pulse, governing hernia, abdominal masses, and accumulation. The intermittent pulse indicates qi decline, or draining of pus and blood, palpitations in cold damage, and in females a three-month pregnancy.
The pulse governing diseases has appropriateness and inappropriateness. Yin-yang compliance or opposition allows one to infer fortune and misfortune.
Wind stroke favors floating and moderate; if an urgent and replete pulse appears, it is taboo. Floating and slippery governs phlegm stroke; deep and slow governs qi stroke. Corpse syncope (fainting and unconsciousness) shows a deep and slippery pulse with sudden loss of consciousness. When evil enters the solid organs, the body is cold; when it enters the hollow organs, the body is warm.
Wind injures the defensive; floating and moderate with sweating (wind stroke with exterior deficiency). Cold injures the nutritive; floating and tight without sweating (cold damage with exterior repletion).
Heat-stroke injures qi; the pulse is vacuous and the body is hot. Dampness injures blood; the pulse is moderate, thin, and rough.
Cold damage febrile disease favors floating and bounding. If deep, faint, rough, and small appear, the pulse is contrary to the syndrome, and it will surely be inauspicious.
After sweating, if the pulse calms and the body cools, there is safety. After sweating, if the pulse is agitated and heat is severe, recovery is difficult.
Yang disease with yin pulse: the disease will certainly be critical. Yin disease with yang pulse: although distressed, there is no harm.
When the pulse does not reach up to Guan, yin qi has ceased. When it does not extend down to Guan, yang qi has been exhausted. The intermittent pulse with pauses indicates the visceral qi is toppling. The scattered pulse without root indicates the body is damaged and difficult to treat.
Internal injury from food and drink: the Qikou pulse is hurried and slippery. Internal injury from overwork: the Spleen pulse is large and weak. To know if it is a qi disease, press down and the pulse is deep. When extremely deep, it becomes hidden. Rough and weak indicates a disease of long duration and deep roots.
Fire depression often shows a deep pulse. Slippery governs phlegm; tight governs food. Qi stagnation produces roughness; blood deficiency produces hollow. Rapid governs fire; thin governs dampness. Slippery governs much phlegm; wiry governs retained rheum. Heat produces slippery and rapid; cold produces wiry and tight. Floating and slippery combined with wind; deep and slippery combined with qi. Food injury produces shortness and hurriedness; dampness retention produces soft and thin.
Malaria has a wiry pulse by nature. Wiry and rapid governs heat; wiry and slow governs cold. Intermittent or scattered indicates danger.
Diarrhea and dysentery favor deep, small, slippery, and weak. If replete, large, floating, or bounding appear, combined with fever, it is unfavorable.
Vomiting and stomach reflux: floating and slippery is auspicious. Wiry, rapid, tight, and rough, with bound intestines, is dangerous.
Cholera: when the intermittent pulse appears, do not be alarmed. Reversal cold with slow and faint pulse is fearsome.
Cough is mostly a floating pulse, with the disease in the Lung, Guan, and Stomach. Deep, tight, and small (as in) danger; hidden and soft (as in) easy to treat.
Asthma and gasping with raised shoulders: floating and slippery is favorable. Deep and rough with cold extremities; the scattered pulse is an adverse sign.
Febrile disease with fire: bounding and rapid can be treated. Deep and faint without fire, pulseless at the root, is dangerous.
Consumptive fever (bone-steaming heat): the pulse is rapid and vacuous. If hot with rough and small, it will certainly damage the body.
Extreme exhaustion and various deficiencies: the pulse is floating, soft, faint, and weak. If the earth is defeated, there is wiry on both sides; if fire flames, there is hurried and rapid.
In all diseases with blood loss, the pulse must show hollow. Moderate and small is auspicious; rapid and large is cause for worry.
Stagnant blood accumulated internally favors firm and large. Deep, small, rough, and faint—on the contrary, this becomes harmful.
Seminal emission and cloudy urine: the pulse is faint, rough, and weak. When fire is exuberant and yin is deficient, hollow, soft, bounding, and rapid may appear.
Three wasting diseases (consumptive thirst): floating and large indicates life. Thin, small, faint, and rough, with bodily wasting, is alarming.
Urinary difficulty and retention: the tip of the nose is yellow. When the pulse is rough and small, there is no blood; when rapid and large, there is no obstruction.
Dry bound stool must be distinguished by qi and blood. Yang syndrome is rapid and replete; yin syndrome is slow and rough.
Depression is double yin; mania is double yang. Floating and bounding is an auspicious sign; deep and hurried is a calamity.
Epilepsy favors a vacuous pulse. Replete and hurried is unfavorable. Floating belongs to yang; deep belongs to yin. Slippery governs phlegm; rapid governs heat.
Throat obstruction: a rapid pulse governs heat; a slow pulse governs cold. In wind-devil throat and galloping horse throat obstruction, faint and hidden is difficult to treat.
Vertigo involves fire and phlegm. Left rough governs dead blood; right large governs deficiency.
Headache is mostly a wiry pulse. Floating governs wind; tight governs cold. Heat brings bounding; dampness brings thin. Moderate and slippery governs reversal phlegm. Qi deficiency brings wiry and soft; blood deficiency brings faint and rough. Kidney reversal brings wiry and firm; true pain brings short and rough.
Heart and abdominal pain has nine categories. Thin and slow is auspicious; floating and large governs prolonged illness.
Hernia: wiry and urgent, with accumulation in the interior. Firm and urgent indicates life; weak and urgent indicates death.
Lower back pain: the pulse is mostly deep and wiry. Combined with floating, it governs wind; combined with tight, it governs cold. Wiry and slippery governs phlegm-rheum; soft and thin governs kidney fixation. Large governs kidney deficiency; deep and replete governs sudden sprain.
Beriberi has four types: slow governs cold; rapid governs heat; floating and slippery governs wind; soft and thin governs dampness.
Atrophy syndrome belongs to Lung deficiency, with the pulse mostly faint and moderate, or rough or tight, or thin or soft.
Wind, cold, and dampness combine to form bi syndrome. Floating, rough, and tight—all three pulses present together.
Five types of jaundice with replete heat: the pulse must be bounding and rapid. Rough and faint indicate deficiency; be certain to avoid the patient becoming thirsty.
When the pulse is deep in all positions, inquire about water build-up. Floating governs qi and wind; deep governs stone or interior. Deep and rapid is yang edema; deep and slow is yin edema. Floating and large governs peril; vacuous and small can be alarming.
Abdominal distension with wiry pulse: Earth is restrained by Wood. Damp-heat brings rapid and bounding; yin cold brings slow and weak. Floating governs deficient distention; tight governs interior repletion. Floating and large is easy to treat; vacuous and small is extremely dangerous.
The five solid organs accumulate; the six hollow organs gather. Replete and strong indicates life; deep and thin indicates death.
Affliction by pestilential evil with abdominal distension: tight and thin indicates life. If the pulse is floating and large, the evil qi has already deepened.
Abscess and flat ulcer: floating and scattered, with aversion to cold and fever. If there is a painful location, it is where the abscess develops. A rapid pulse with fever and pain indicates a yang condition. No rapidity, no heat, and no pain indicates a yin sore. Before an abscess ruptures, do not fear a bounding and large pulse. After an abscess has ruptured, bounding and large is fearsome.
Lung abscess already formed: Cun is rapid and replete. Lung withering shows a rapid but weak pulse. Lung abscess with white complexion: the pulse favors short and rough, and does not favor floating and large. Spitting paste and vomiting blood is critical. Yang abscess with replete heat: slippery and rapid can be known. Rapid but not hot: the Guan pulse is hollow and vacuous. Faint, rough, and tight: when the pus has not yet formed, one should descend. When tight and rapid, the pus has already formed—by no means descend.
The pulse of women is rooted in blood. When blood is abundant, pregnancy is easy; when qi is abundant, pregnancy is difficult. When the Shaoyin pulse moves strongly, it is called having a child. When the Chi pulse is slippery and flowing, pregnancy is pleasing. Slippery and hurried yet not scattered: the fetus must be three months. Hurried but not scattered: at five months it can be distinguished. Left hurried indicates male; right hurried indicates female. The female abdomen is like a winnowing basket; the male abdomen is like an axe.
The pulse of impending labor departs from the regular order of the meridians when its beats are like wandering. When the amniotic fluid has released, labor will follow; if it has not released, do not be alarmed.
The pulse of a new mother: moderate and slippery is auspicious. Replete, large, wiry, and firm, if accompanied by complications, is adverse.
The pulse of children: seven beats per breath-cycle is normal. One must further observe the complexion and the tiger's mouth lines.
The diagnosis of the eight extraordinary vessels has its own distinctions. Straight up and straight down, floating then it is the Governor Vessel. Firm then it is the Thrusting Vessel. Tight then it is the Conception Vessel. With the Cun region springing left and right, one diagnoses the Yang Heel Vessel. With the Chi region springing left and right, one diagnoses the Yin Heel Vessel. With the Guan region springing left and right, one diagnoses the Girdle Vessel. Slanting upward from outside Chi to Cun is the Yin Linking Vessel. Slanting upward from inside Chi to Cun is the Yang Linking Vessel.
When the Governor Vessel is diseased: stiff spine and epilepsy. When the Conception Vessel is diseased: the seven hernias, accumulations, and hardness. When the Thrusting Vessel is diseased: counterflow qi and internal urgency. The Girdle Vessel governs vaginal discharge, umbilical pain, and seminal loss. The Yang Linking Vessel governs chills and fever, dizziness, and rigid prostrate posture. The Yin Linking Vessel governs heart pain, chest and hypochondriac stabbing pain with cramping. When the Yang Heel Vessel is diseased, the outer is relaxed and the inner is urgent. When the Yin Heel Vessel is diseased, the inner is relaxed and the outer is urgent. Epilepsy and convulsions, chills and fever, and mental confusion. The eight vessels: each has its own dominion of pulse and syndrome.
When the pulse of a healthy person does not manifest at Cunkou, it shifts to the external collaterals. When the sibling positions interchange, such as Yangxi and Lieque.
With the disease pulses now clear, fortune and misfortune should be distinguished. Beyond the regular channels, there are also true visceral pulses (critical pulse patterns that appear when the true qi of the viscera is exhausted).
Liver exhaustion pulse: like pressing along a knife blade—hard, thin, and urgent. Heart exhaustion pulse: agitated like a rolling bean. Spleen exhaustion appears like a sparrow pecking at food, like drops leaking from a roof, like water flowing, like a cup overturned. Lung exhaustion is like a feather—rootless and desolate, like sesame seeds trembling, like floating waves meeting. Kidney pulse about to exhaust: arrives hurriedly like a visiting guest, arrives like flicking a stone, departs like untying a rope. Life pulse about to exhaust: like a shrimp swimming or a fish gliding, arrives like a flowing spring, ending in the Bladder.
When the true visceral pulse appears, it indicates that stomach qi has been exhausted. Then reference the complexion and symptoms to comprehensively judge the prognosis.
The opening of Siyan Juyao establishes the fundamental principle of pulse diagnosis: the pulse is the manifestation of qi and blood movement. The pulse does not move on its own but follows qi—this is the most core understanding in TCM pulse diagnosis: the pulse is not a simple reflection of heartbeats, but a comprehensive manifestation of the state of qi and blood throughout the body. This is fundamentally different from modern medicine, which views the pulse as an indicator of cardiovascular function. Traditional Chinese medicine holds that through the Cunkou (radial pulse point)—the "place of confluence"—the functional states of the five viscera and six bowels can be read.
Why is it that all twelve channels have arteries, yet only the Cunkou of the Hand-Taiyin Lung Channel is selected? The ancients reasoned that: the Lung Channel connects upward to the throat, serving as the great confluence of the pulse, with respiration entering and exiting in correspondence. The deeper logic lies in: the Lungs govern qi and orient the hundred vessels—the Lungs command the qi of the entire body, and all vessels converge upon the Lungs. Cunkou is where the Yuan-Source point of the Lung Channel is located, hence it can reflect the qi and blood of the whole body. This mode of thinking—"a part reflecting the whole"—is the fundamental paradigm of TCM diagnostic methodology.
This chapter's most incisive contribution lies in distilling the vast body of pulse theory into four cardinal categories: Floating, Sinking, Slow, and Rapid. These four dimensions correspond to:
| Dimension | Meaning | Corresponding Relationship |
|---|---|---|
| Floating/Sinking | Depth of pulse location | Interior-Exterior differentiation (disease location) |
| Slow/Rapid | Pulse rate | Cold-Heat differentiation (disease nature) |
This constructs the diagnostic framework of exterior-interior and cold-heat, further differentiated by strength or weakness to distinguish deficiency-excess, forming the prototype of the complete Eight-Principle Differentiation system. This was a critical step in TCM diagnostics evolving from empirical experience toward systematic organization.
The text repeatedly emphasizes "pulse-syndrome cross-reference"—that pulse findings must be interpreted in conjunction with symptoms. The same pulse pattern has different meanings in different diseases (e.g., a Floating pulse indicates exterior conditions, deficiency, or wind), and different pulse patterns in the same disease carry distinctions of favorable or unfavorable prognosis (e.g., diarrhea is favorable when the pulse is Deep, Slow, Slippery, and Weak, but unfavorable when Full, Large, Floating, and Surging). This mode of thinking—"within constancy there is variation, within variation there is constancy"—is the essence of TCM clinical reasoning.
The text reiterates throughout that "for all seasons and all diseases, Stomach Qi is the foundation." The reason genuine organ pulses (Zhenzang Mai) are so ominous is fundamentally that "the Stomach has lost qi." Stomach Qi refers to the acquired qi transformed from the body's digestive and absorptive functions—the material foundation of life. Regardless of the disease, as long as Stomach Qi remains, and the pulse retains "spirit" (calm and gentle), the prognosis is good; when Stomach Qi has failed completely, the disease has advanced deeply.
Spring-wiry, summer-full, autumn-floating, winter-stone—the pulse changes with the four seasons, which is essentially the body's qi and blood following natural rhythms. If the pulse contradicts the season (e.g., an autumn pulse appearing in spring), it indicates that the body's regulatory capacity is already disordered, with a poor prognosis. This "season-pulse-disease" triadic correspondence reflects TCM chronomedicine.
The text's "harmonize your qi, stabilize the breath, four to five beats—the standard of tranquility" suggests: the rhythm of breathing directly affects the rhythm of the pulse. In daily life, one can consciously slow and deepen the breath to promote coordination between breathing and heart rate, aiding physical and mental relaxation and autonomic nervous system balance. This offers traditional wisdom echoing modern breathing training (e.g., slow diaphragmatic breathing at 6 breaths per minute can improve heart rate variability).
"Spring-wiry, summer-full, autumn-floating, winter-stone" reminds us that the body's qi and blood naturally ebb and flow with the seasons—and this is a sign of health. Modern research confirms that blood pressure, heart rate, and endocrine function exhibit seasonal rhythms. Wellness should follow the seasons—spring for expansion, summer for nurturing the heart, autumn for contraction, winter for storage—rather than resisting natural rhythms.
The core message of "for all seasons and all diseases, Stomach Qi is the foundation" is: digestive function is the foundation of life. Maintaining regular eating patterns, avoiding extremes of hunger or fullness, and preventing dietary imbalances is fundamental to preserving all aspects of health. No matter how busy daily life becomes, the spleen and stomach functions must be protected.
"Joy, anger, worry, brooding, sorrow, fear, and fright" as internal causes can produce abnormal pulse patterns. Modern psychosomatic medicine also confirms that emotional fluctuations affect heart rate and vascular tone. Daily life calls for cultivating emotional balance, avoiding prolonged accumulation of anxiety, anger, and depression. Traditional practices such as seated meditation and standing postures, in essence, regulate both the pulse and qi through the process of breath harmonization.
Learning about pulse diagnosis can help us understand abnormal bodily signals—for example, a pulse that suddenly becomes irregular, extremely fast or slow, or inconstant in strength are all warning signs worth attention. However, never self-diagnose based on this knowledge. Pulse diagnosis is a clinical skill acquired through long-term training and requires integration with all four diagnostic methods by licensed TCM practitioners. Casual study aids wellness awareness, but any discomfort warrants prompt professional medical attention.
| Concept | Explanation |
|---|---|
| Nutritive & Defensive Qi | Nutritive qi travels within the vessels, transforming into blood and nourishing the whole body; Defensive qi travels outside the vessels, warming the skin and resisting pathogens. Their relationship resembles an analogy for "nutritional supply" versus "immune defense" |
| Cunkou | The radial artery pulsation point at the wrist, divided into Cun, Guan, and Chi positions. Cun is proximal (distal), Chi is distal (proximal). The standard site for TCM pulse taking |
| Seven Diagnoses and Nine Signs | The seven diagnoses: Floating, Medium, Sinking (depth of finger pressure) + Upper, Lower (position) + Left, Right (two hands); Nine signs: three positions (Cun, Guan, Chi) × three depths (Floating, Medium, Sinking), forming the "three positions and nine signs" system |
| Four Cardinal Pulses | Floating, Sinking, Slow, and Rapid are the four major canonical pulses, governing all 28 common pulse patterns—the foundational framework for learning pulse diagnosis |
| Genuine Organ Pulse | Also known as "abnormal pulse" or "death pulse"—pathological pulses appearing when Stomach Qi has failed, regarded in antiquity as indicating critical illness |
| Eight Extraordinary Vessels | Du, Ren, Chong, Dai, Yangqiao, Yinqiao, Yangwei, and Yinwei—eight vessels complementing the twelve primary channels, primarily regulating the storage and overflow of qi and blood |
| Stomach Qi | In TCM, refers to the transformative function of the spleen and stomach and the essential qi derived from water and grain—the material foundation of postnatal life. A pulse possessing "Stomach Qi" manifests as calm, gentle, and vigorous |

— Budiao notes: With this, the study of the complete Binhu Maixue concludes. From the four cardinal pulses of Floating, Sinking, Slow, and Rapid, to the individual discussions of the 27 pulse patterns, to the clinical synthesis of Siyan Juyao, Li Shizhen constructed a complete educational system for foundational pulse studies in poetic verse form. May the learner grasp its principles and methods, know its boundaries, and proceed with scholarship in the mind and rationality on the path.
