Why can Chinese medicine know a pulse like the back of his hand?

Pulse diagnosis method Pulse diagnosis method includes Cunkou, Renying Cunkou and Zhang Zhongjing. Village entrance is often used now. The pulse diagnosis site is the inside of the wrist, next to the high bone (styloid process of radius) behind the wrist, where the radial artery beats. The pulse position of radial artery corresponding to high bone is off, before off, inch and after off. The name of "Cungui" was first seen in Neijing, and the "Cunkou Diagnosis Method" was developed in the difficult classics. Inch, Guan and Chi correspond to different viscera respectively. Left hand inch corresponds to the heart, Guan corresponds to the liver, and red corresponds to the kidney (kidney water). The inch of the right hand corresponds to the lung, the Guan corresponds to the spleen, and the ruler corresponds to the kidney (life gate). Holism and syndrome differentiation are two concepts in the basic theory of traditional Chinese medicine. Traditional Chinese medicine is a combination of observation, hearing, questioning and palpation, and it is not appropriate to diagnose and treat diseases as a whole with only one diagnostic method. The information of human body is not only reflected in pulse condition, but also in skin surface, sound, smell and so on. It's just that the pulse condition is single and incomplete, which is easy to produce errors. Each of the four diagnostic methods has its own characteristics and unique functions. Pulse diagnosis can not replace other diagnostic methods, but should combine the four diagnosis methods to improve the accuracy of diagnosis. The pulse condition of common diseases in healthy people should be four breaths at a time, three pulses in inches, gentle and strong, and the ruler pulse should be strong. Common pulse diseases include floating pulse, sinking pulse, late pulse, multiple pulse, deficiency pulse, solid pulse, slippery pulse, extensive pulse, thin pulse and chord pulse. Floating pulse: press lightly to get it, then press again to decrease it. It is characterized by superficial pulse position. Main symptoms: Exterior syndrome is characterized by exterior pulse position because exogenous pathogenic factors stay in exterior, and defensive qi does not invade pathogenic factors, so that pulse qi is excited externally. Strong floating is the real thing; Floating without strength is superficial. Long-term internal injuries are caused by deficiency of yin and blood, deficiency of yang, yang deficiency floating outward and weak pulse. Sink pulse: you can't press it lightly, just press it again. It is characterized by deep pulse position. Main symptoms: interior syndrome. Strength is the inner reality, and weakness is the inner weakness. Pathogenic qi is depressed inside, qi and blood block yang, and the pulse is heavy and powerful. Visceral weakness, yang deficiency and qi stagnation, rapid pulse weak gas, weak pulse. Late pulse: slow pulse, (less than 60 pulses per minute). Main symptoms: cold syndrome. Strong is cold, weak is cold. Cold is depressed, qi and blood move slowly, and the pulse is slow and strong, which is the syndrome of excess cold. Deficiency of Yang Qi, inability of qi and blood to move, and slow and weak pulse are the syndromes of deficiency and cold. Athletes and heavy manual workers often have a late pulse, which is a physiological state. Pulse count: rapid pulse, (pulse is more than 90 times per minute). Its characteristic is that the pulse is faster than the normal pulse. Main symptoms: heat syndrome. Strong is excess heat, weak is deficiency heat. Exogenous fever starts at the beginning, viscera is full of heat, pathogenic heat is stimulated, blood circulation is accelerated, and strong pulse is excess heat. Blood deficiency, body fluid deficiency, blood deficiency, endogenous deficiency heat, pulse number and weakness are deficiency heat. Deficiency pulse: all three pulses are weak. Press empty again. It should mean softness, which is the general term for all weak veins. Main symptoms: deficiency syndrome: mostly due to deficiency of both qi and blood, the pulse condition is difficult to stimulate, so it is deficiency. True pulse: All three pulses are powerful. Main symptoms: empirical evidence: pathogenic qi is abundant and healthy qi is sufficient, and both positive and evil are contending, and qi and blood are full of pulse. Slippery pulse: it should mean smooth, smooth pressing, as smooth as pressing a ball. Main symptoms: phlegm, indigestion and excess heat, which are more common in young people with deficiency of both qi and blood. The slippery pulse of pregnant women is a phenomenon of vigorous qi and blood to raise the fetus. They are all physiological phenomena. Hong pulse: The pulse is large and powerful, like a rough wave, one after another. Come and grow. Main symptoms: excess heat. The internal heat is strong, the pulse channels are dilated and the pulse shape is wide. Due to excessive heat, pathogenic factors are blazing, qi and blood are full, and pulse conditions are fluctuating. Pulse: the pulse is as thin as a line, with obvious fluctuation. Main symptoms: deficiency syndrome, mostly seen in yin deficiency and blood deficiency syndrome. It also controls wet diseases. Yin deficiency and blood deficiency can't fill the pulse, or wet evil can't fill the pulse, and the pulse is small. Chord pulse: the end is straight and long, pointing down quite suddenly, such as pressing a chord. Treat hepatobiliary diseases, pain syndrome and phlegm. The qi is unfavorable, the liver loses the function of dispersing qi, and the pulse is tense and shows a string pulse. When the patient is sick, qi disorder or phlegm stops, which will lead to poor conduction of qi and string pulse. Pulse knot: slow pulse and irregular interval. Main diseases: yin deficiency and qi stagnation, cold phlegm and blood stasis. Analysis: Yin cold is the internal knot, and the qi of the pulse channel is blocked, so the pulse comes slowly and stops for a while. Cold phlegm and blood stasis, qi stagnation, stagnation of pulse qi, therefore, if the pulse stops late due to qi deficiency and weak blood, it is weak. Pulse generation: the pulse has a rest and a fixed number. Main disease: Decline of dirty qi. Analysis: the dirty qi is weak, the vitality is insufficient, and the pulse is blocked. Normal pulse condition The pulse condition of a normal person is also called flat pulse and normal pulse. The regular pulse condition has three pulses, one breath and four pulses (70-80 pulses per minute earlier), neither floating nor sinking, neither too big nor too small, with even rhythm, calm and gentle, smooth and powerful, and inexhaustible ruler and pulse. It's called having a stomach, spirit and roots. Among them, there is stomach, that is, there is stomach qi, and the pulse is gentle, calm, smooth and energetic; God means that the pulse should be strong and soft, and the rhythm should be neat; Have roots. The main manifestation is endless ulnar pulse. In addition, the pulse condition is closely related to the internal and external environment. Due to the influence of climate, age, sex, physique, rest and mental state, pulse conditions will also undergo some physiological changes. For example, throughout the year, the pulse condition has the changes of spring string, summer flooding, autumn floating and winter sinking; The younger the age, the faster the pulse; Baby's pulse is fast, young adults' pulse is strong, old people's pulse is slightly string, and women's pulse is weak and slightly faster than men's. The fat contact is slightly heavier and the thin contact is slightly floating; After work, the pulse is fast and strong when drinking, full or emotional, and weak when hungry; The pulse of mental workers is much weaker than that of manual workers These should be distinguished from the pulse of the disease. In addition, the radial artery of a few people is abnormal, and there is no pulse at the mouth of the inch. If it appears behind the cunkou, it is called "anti-Guan pulse"; Some are inclined from the foot to the back of the hand, which is called "oblique flying pulse". This is not a disease.
