玉机真藏篇曰∶脉从四时，谓之可治。脉弱以滑，是有胃气，命曰易治，取之以时。
春脉者肝也，东方木也，万物之所以始生也。故其气来，软弱轻虚而滑，端直以长曰弦，反
此者病。其气来实而强，此谓太过，病在外；其气来不实而微，此谓不及，病在中。太过则令人
善怒，忽忽眩冒而巅疾，不及则令人胸痛引背，下则两 满。春以胃气为本，春胃微弦曰平，弦
多胃少曰肝病，但弦无胃曰死。胃而有毛曰秋病，毛甚曰今病。
夏脉者心也，南方火也，万物之所以盛长也。故其气来盛去衰曰钩，反此者病。其气来盛去
亦盛，此谓太过，病在外；其气来不盛去反盛，此谓不及，病在中。太过则令人身热肤痛为浸淫，
不及则令人烦心，上见咳唾，下为气泄。
夏以胃气为本，夏胃微钩曰平，钩多胃少曰心病，但钩无胃曰死。胃而有石曰冬病，石甚曰今病。
秋脉者肺也，西方金也，万物之所以收成也。其气来轻虚以浮、来急去散曰毛，反此者病。
其气来毛而中
央坚两傍虚，此谓太过，病在外；其气来毛而微，此谓不及，病在中。太过则令人逆气而背痛，
不及则令人喘、呼吸少气而咳，上气出血、下闻病音。
秋以胃气为本，秋胃微毛曰平，毛多胃少曰肺病，但毛无胃曰死。胃而有弦曰春病，弦甚曰今病。
冬脉者肾也，北方水也，万物之所以合藏也，其气来沉而搏曰石，反此者病。其气来如弹石，
此谓太过，病在外；其去如数，此谓不及，病在中。太过则令人解 ，脊痛而少气，不欲言，不
及则令人心悬如病饥， 中清，脊中痛，少腹满，小便变。
冬以胃气为本，冬胃微石曰平，石多胃少曰肾病，但石无胃曰死。石而有钩曰夏病，钩甚曰今病。
脾脉者土也，孤藏以灌四傍者也。平脾脉来，如鸡践地，和柔相离。其来如水之流，此谓太
过，病在外；如鸟之啄，此谓不及，病在中。太过则令人四肢不举，不及则令人九窍不通。
长夏以胃气为本，胃惟软弱曰平，弱多胃少曰脾病，但代无胃曰死，软弱有石曰冬病，石甚曰今病。
脉逆四时为不可治，必察四难而明告之。所谓逆四时者，春得肺脉，夏得肾脉，秋得心脉，
冬得脾脉，其至皆悬绝沉涩者，命曰逆四时。未有脏形，于春夏而脉沉涩，秋冬而脉洪大名曰逆
四时也。
凡脉顺四时者，谓春弦夏洪秋毛冬石，中有和气，软滑而长，乃是不病之人也，得病则易为
治疗，盖从和气而生也，用法万痊。如气反脉逆，形气相失，名曰不可治，是形盛气虚、形虚气
盛，故不可治也。凡人形气俱虚，安谷者过期而死，不安谷者不过期而死。安谷谓饮食且进，期
是八节之气候也。（《鸡峰方》）

The *Yu Ji Zhen Cang Pian* (Chapter on the True Visceral Pulses of the Jade Machine) states: When the pulse conforms to the four seasons, it is termed treatable. A pulse that is weak and slippery indicates the presence of Stomach Qi (the source of qi and blood generation derived from spleen and stomach transformation), which is termed easily treatable; treatment should be timed appropriately.
The Spring pulse corresponds to the Liver, belonging to Wood in the East, representing the time when all things begin to grow. Therefore, its qi arrives soft, weak, light, empty, and slippery, straight and long, termed Xian pulse (String-like pulse, feeling like a zither string); deviation from this indicates disease. If the qi arrives solid and strong, this is termed "Excess" (Tai Guo), with disease located externally; if the qi arrives not solid but faint, this is termed "Deficiency" (Bu Ji), with disease located internally. Excess causes irritability, dizziness, vertigo, and diseases of the vertex (Dian Ji). Deficiency causes chest pain radiating to the back, and fullness in the lower bilateral hypochondriac regions. The Spring pulse takes Stomach Qi as its root. A Spring pulse slightly Xian is a Normal Pulse (Ping Mai); Xian more than Stomach Qi indicates Liver disease; only Xian without Stomach Qi indicates death. If there is Stomach Qi but also Mao pulse (Floating and rough like feathers, characteristic of Autumn), disease will occur in Autumn; pronounced Mao indicates disease occurring now.
The Summer pulse corresponds to the Heart, belonging to Fire in the South, representing the time when all things flourish and grow. Therefore, its qi arrives vigorous and departs declining, termed Gou pulse (Hook pulse, arriving vigorously and departing weakly); deviation from this indicates disease. If the qi arrives vigorous and departs vigorous, this is termed "Excess," with disease located externally; if the qi arrives not vigorous but departs vigorous, this is termed "Deficiency," with disease located internally. Excess causes body heat, skin pain, progressing to Jin Yin sores (spreading dermatological conditions). Deficiency causes mental restlessness, coughing and expectoration above, and Qi leakage (such as incontinence or diarrhea) below.
The Summer pulse takes Stomach Qi as its root. A Summer pulse slightly Gou is a Normal Pulse; Gou more than Stomach Qi indicates Heart disease; only Gou without Stomach Qi indicates death. If there is Stomach Qi but also Shi pulse (Sinking and solid like stone, characteristic of Winter), disease will occur in Winter; pronounced Shi indicates disease occurring now.
The Autumn pulse corresponds to the Lung, belonging to Metal in the West, representing the time when all things are harvested and stored. Its qi arrives light, empty, and floating, coming urgently and dispersing upon departure, termed Mao pulse; deviation from this indicates disease. If the qi arrives Mao but is firm in the center and empty on both sides, this is termed "Excess," with disease located externally; if the qi arrives Mao but faint, this is termed "Deficiency," with disease located internally. Excess causes rebellious Qi and back pain. Deficiency causes panting, shortness of breath, and coughing, upper rebellious Qi with bleeding, and audible pathological sounds below.
The Autumn pulse takes Stomach Qi as its root. An Autumn pulse slightly Mao is a Normal Pulse; Mao more than Stomach Qi indicates Lung disease; only Mao without Stomach Qi indicates death. If there is Stomach Qi but also Xian pulse, disease will occur in Spring; pronounced Xian indicates disease occurring now.
The Winter pulse corresponds to the Kidney, belonging to Water in the North, representing the time when all things are closed and stored. Its qi arrives sinking and beating against the finger, termed Shi pulse; deviation from this indicates disease. If the qi arrives hard like a bouncing stone, this is termed "Excess," with disease located externally; if the qi departs rapid (Shu), this is termed "Deficiency," with disease located internally. Excess causes muscle flaccidity (Xie Ji), back pain, shortness of breath, and reluctance to speak. Deficiency causes a sensation of heart hanging as if hungry, coldness at the umbilicus, back pain, lower abdominal fullness, and abnormal urination.
The Winter pulse takes Stomach Qi as its root. A Winter pulse slightly Shi is a Normal Pulse; Shi more than Stomach Qi indicates Kidney disease; only Shi without Stomach Qi indicates death. If there is Stomach Qi but also Gou pulse, disease will occur in Summer; pronounced Gou indicates disease occurring now.
the Spleen pulse corresponds to Earth. It is the isolated central Zang organ that irrigates the four directions (other four Zang organs). A normal Spleen pulse arrives like a chicken treading on ground, harmonious and soft with distinct rhythm. If it arrives like flowing water, this is termed "Excess," with disease located externally; if it arrives like a bird pecking, this is termed "Deficiency," with disease located internally. Excess causes inability to lift the limbs. Deficiency causes obstruction of the Nine Orifices (eyes, ears, nose, mouth, and two anterior/posterior orifices).
The Chang Xia (Late Summer) pulse takes Stomach Qi as its root. A pulse with only softness is a Normal Pulse; weakness more than Stomach Qi indicates Spleen disease; only Dai pulse (intermittent pulse with regular intervals) without Stomach Qi indicates death; softness combined with Shi pulse indicates disease in Winter; pronounced Shi indicates disease occurring now.
A pulse contrary to the four seasons is untreatable; one must carefully examine the four difficulties and clearly inform the patient. What is meant by contrary to the four seasons is: obtaining the Lung pulse (Mao) in Spring, the Kidney pulse (Shi) in Summer, the Heart pulse (Gou) in Autumn, and the Spleen pulse (Dai/Weak) in Winter, where these pulses arrive suspended, extreme, sinking, and choppy, termed contrary to the four seasons. Without visceral morphological signs, if the pulse is sinking and choppy in Spring and Summer, or large and prominent in Autumn and Winter, this is also termed contrary to the four seasons.
Whenever the pulse conforms to the four seasons, termed Spring Xian, Summer Hong (Gou), Autumn Mao, and Winter Shi, containing Harmonious Qi (Stomach Qi), being soft, slippery, and long, this characterizes a person without disease. If such a person becomes ill, it is easy to treat because it arises from Harmonious Qi, and medication often leads to complete recovery. If Qi is contrary and pulse is rebellious, and Form and Zheng Qi are discordant, it is termed untreatable, because this represents Form excess with Zheng Qi deficiency, or Form deficiency with Zheng Qi excess, hence untreatable. Generally, if a person's Form and Qi are both deficient, those who can eat will die after exceeding the expected period, while those who cannot eat will die before exceeding the expected period. "An Gu" refers to the ability to ingest food. "Qi" refers to the climatic cycles of the Eight Solar Terms (Li Chun, Li Xia, Li Qiu, Li Dong, Chun Fen, Qiu Fen, Xia Zhi, Dong Zhi).
