黄帝问曰∶人有四经十二从，何谓？岐伯对曰∶四经应四时，十二从应十二月，十二月应十二脉。
脉有阴阳，知阳者知阴，知阴者知阳。凡阳有五，五五二十五阳。所谓阴者，真脏也，见则为败，败必死
也。所谓阳者，胃脘之阳也。别于阳者，知
病处也；别于阴者，知死生之期。三阳在头，三阴在手，所谓一也。别于阳者，知病忌时；别于阴者，知
死生之期。谨熟阴阳，无与众谋。所谓阴阳者，去者为阴，至者为阳；静者为阴，动者为阳；迟者为阴，数
者为阳。凡持真脉之脏脉者，肝至悬绝急，十八日死；心至悬绝，九日死；肺至悬绝，十二日死；肾至悬绝，
七日死；脾至悬绝，四日死。曰∶二阳之病发心脾，有不得隐曲，女子不月；其传为风消，其传为息
贲者，死不治。曰∶三阳为病发寒热，下为痈肿，及为痿厥 ；其传为索泽，其传为颓疝。曰∶一阳
发病，少气善咳善泄；其传为心掣，其传为隔。二阳一阴发病，主惊骇背痛，善噫善欠，名曰风厥。二
阴一阳发病，善胀心满善气。三阳三阴发病，为偏枯痿易，四肢不举。鼓一阳曰钩，鼓一阴曰毛，鼓阳
胜急曰弦，鼓阳至而绝曰石，阴阳相过曰溜。阴争于内，阳扰于外，魄汗未藏，四逆而起，起则熏肺，使人
喘鸣。阴之所生，和本曰和。是故刚与刚，阳气破散，阴气乃消亡。淖则刚柔不和，经气乃绝。死阴之属，不
过三日而死；生阳之属，不过四日而死。所谓生阳死阴者，肝之心谓之生阳，心之肺谓之死
阴，肺之肾谓之重阴，肾之脾谓之辟阴，死不治。结阳者，肿四肢。结阴者，便血一升，再结二升，
三结三升。阴阳结斜，多阴少阳曰石水，少腹肿。二阳结谓之消，三阳结谓之隔，三阴结谓之水，一阴一
阳结谓之喉痹。阴搏阳别谓之有子。阴阳虚肠辟死。阳加于阴谓之汗。阴虚阳搏谓之崩。三阴俱搏，
二十日夜半死。二阴俱搏，十三日夕时
死。一阴俱搏，十日死。三阳俱搏且鼓，三日死。三阴三阳俱搏，心腹满。发尽不得隐曲，五日死。二
阳俱搏，其病温，死不治，不过十日死。
阴阳应象大论∶ 胀（上昌真切，肉胀起也）渗泄（上所禁切）翕 （下许极切）哕噫（上乙劣切，
下乌界切）能冬（上奴代切，下能夏、形能并同）放效（上妃两切）并于（上去声）嗌（伊芳者切）
滑涩（下音色）渍（即赐切）
阴阳离合论∶予（犹与也）
阴阳别论∶ （音喘，腓肠也） （音渊，疼也）淖（音淘，水朝宗于海）
Huangdi asked: "There are four meridians and twelve 'cong' (following/secondary pathways) in the human body. What does this mean?" Qibo replied: "The four meridians correspond to the four seasons, the twelve 'cong' correspond to the twelve months, and the twelve months correspond to the twelve primary meridians."
Pulses have Yin and Yang characteristics; understanding Yang pulses implies understanding Yin pulses, and vice versa. There are five types of Yang pulses, and five times five equals twenty-five Yang pulse patterns. The so-called Yin pulses refer to the Zang-Fu organ-specific pulses (True Visceral Pulses, i.e., pulses devoid of Stomach Qi); their appearance indicates the collapse of visceral essence and inevitably leads to death. The so-called Yang pulses refer to the Yang of the Stomach cavity (Stomach Qi manifested in the pulse). By distinguishing Yang pulses, one can locate the disease; by distinguishing Yin pulses, one can predict the timing of death or survival. The Qi of the three Yang meridians is found at the head, and the Qi of the three Yin meridians is found at the hands; this is referred to as "One." By distinguishing Yang, one knows the time of onset and contraindications; by distinguishing Yin, one knows the prognosis of life and death. One must thoroughly master Yin and Yang theory without needing to consult others. Regarding Yin and Yang: departing is Yin, arriving is Yang; stillness is Yin, movement is Yang; slowness is Yin, rapidity is Yang. When palpating the True Visceral Pulses of the organs: if the Liver pulse is suspended, isolated, and rapid, death occurs in eighteen days; if the Heart pulse is suspended, death occurs in nine days; if the Lung pulse is suspended, death occurs in twelve days; if the Kidney pulse is suspended, death occurs in seven days; if the Spleen pulse is suspended, death occurs in four days. It is said: Diseases of the Er-Yang (Yangming Stomach and Large Intestine meridians) originate in the Heart and Spleen, manifesting as difficult-to-disclose ailments (such as sexual dysfunction or defecation difficulties), and amenorrhea in women; if it transmits to Fengxiao (wasting syndrome with muscle emaciation) or Xiben (asthma with chest fullness), it results in untreatable death. It is said: Diseases of the San-Yang (Taiyang Bladder and Small Intestine meridians) manifest as alternating chills and fever, abscesses/swelling in the lower body, and Wei-Jue (limb flaccidity and cold extremities); if it transmits to Suoze (dry, lusterless skin) or Tuihan (scrotal hernia/swelling), the condition worsens. It is said: Disease of Yi-Yang (Shaoyang Gallbladder and Sanjiao meridians) manifests as shortness of breath, frequent coughing, and frequent diarrhea; if it transmits to Xinche (pulling pain in the heart) or Ge (obstruction/dysphagia), the condition worsens. Simultaneous disease of Er-Yang and Yi-Yin manifests primarily as fright, back pain, frequent belching, and yawning, named Fengjue (Wind Jue). Simultaneous disease of Er-Yin and Yi-Yang manifests as frequent abdominal distension, chest fullness, and frequent sighing. Simultaneous disease of San-Yang and San-Yin manifests as hemiplegia, interchange between flaccidity and ease of movement, and inability to move the limbs. A pulse beating strongly like a hook (surging) is called a Hook pulse; beating lightly and floating like a feather is called a Feather pulse; beating strong and tense is called a String-like pulse; beating deep, solid, and seemingly cut off is called a Stone pulse; Yin and Yang qi interweaving is called a Slipping pulse. If Yin contends internally and Yang disturbs externally, Po-han (profuse sweating) fails to consolidate, leading to Si-ni (cold extremities); rising from this state, the pathogenic heat steams the Lungs, causing wheezing and stridor. The harmonious state generated by Yin is called "Harmony." Therefore, when Rigidity meets Rigidity, Yang Qi is broken and scattered, and Yin Qi perishes. If too soft/watery, rigidity and flexibility are discordant, and Jing-Qi (Meridian Qi) severs. Diseases belonging to Dead Yin do not exceed three days before death; diseases belonging to Living Yang do not exceed four days before death. Regarding Living Yang and Dead Yin: Liver transmitting to Heart is Living Yang; Heart transmitting to Lung is Dead Yin; Lung transmitting to Kidney is Heavy Yin; Kidney transmitting to Spleen is Pi-Yin (Rebellious Yin); these are all untreatable deaths. Yang Qi knotting leads to swelling of the four limbs. Yin Qi knotting leads to blood in stool: first knotting causes one sheng of bleeding, second knotting two sheng, third knotting three sheng. Yin and Yang knotting with deviation, characterized by excess Yin and deficient Yang, is called Shi-Shui (Stone Water), presenting with lower abdominal swelling. Knotting of Er-Yang is called Xiao (Wasting-Thirst/Diabetes); knotting of San-Yang is called Ge (Obstruction/Dysphagia); knotting of San-Yin is called Shui (Edema/Water retention); knotting of Yi-Yin and Yi-Yang is called Hou-Bi (Throat Bi/Obstruction). Yin pulse beating forcefully and distinctly separate from Yang indicates pregnancy. Deficiency of both Yin and Yang leading to Chang-Pi (dysentery) results in death. Yang added to Yin indicates sweating. Yin deficiency with forceful Yang beating indicates Beng-Loose (metrorrhagia/heavy uterine bleeding). If all three Yin pulses beat forcefully, death occurs on the twentieth day at midnight. If all two Yin pulses beat forcefully, death occurs on the thirteenth day at dusk. If all one Yin pulse beats forcefully, death occurs in ten days. If all three Yang pulses beat forcefully and surge, death occurs in three days. If all three Yin and three Yang pulses beat forcefully, there is fullness in the heart and abdomen. If symptoms fully manifest along with difficult-to-disclose ailments, death occurs in five days. If both Er-Yang pulses beat forcefully, the disease is Wen-Bing (Warm Disease); it is untreatable and death occurs within ten days.
