黄帝曰∶善言天者，必验于人。善言古者，必合于今。善言人者，必厌于己。如
道不惑，所谓明也。余问夫子，言而可知，视而可见，扪而可得。今验于发蒙解惑，可
得闻乎？岐伯稽首对曰∶何道之间也！天覆地载，万物番备，莫贵于人。人以天地之气
生，四时之法成。君王宰职黎庶，尽欲全角。贵贱虽殊，宝命一矣，好生恶死者，是世人之常
也。若人有患，如救水火，莫待留淫日深，着于骨髓，所以难矣。
煎厥之状，阳气烦劳，精绝，辟积于夏，致目盲不可视，耳闭不可听。薄厥之状，
阳气大怒，形气绝而血菀于上。 胀、飧泄，寒热不散，升降上下。颓疝、心掣，寒

肺移寒于肾。为涌水。心移热

热盛则阳络溢，阳络溢为衄 。醉以入房，气竭伤肝，大脱其血，月事衰少，名曰血枯。

黄帝说：善于谈论天道的人，必定能在人体上得到验证。善于谈论古代道理的人，必定能契合当今实际。善于谈论人体生理病理的人，必定能反求诸己、切身体会。如果不被迷惑，这就叫做“明”。我问先生，言语可以知晓，观察可以看见，触摸可以感知。现在希望像启发蒙昧、解除困惑一样，能够听您详细讲讲吗？
岐伯叩头回答说：您问的是什么道呢！天覆盖在上，地承载在下，万物都具备齐全，没有比人更宝贵的了。人依靠天地之气而生，遵循四时规律而成长。君王和官员治理百姓，都希望保全人的形体与生命。虽然地位贵贱不同，但珍视生命的本质是一样的，喜好生存厌恶死亡，这是世人的常情。如果人有了疾病，就像救火或救人溺水一样紧急，不要等到病邪滞留浸淫日久，深入骨髓，那样就难治了。
煎厥的症状是：阳气因过度烦劳而亢盛，导致精气枯竭，这种状况在夏季反复积累，致使双目失明无法视物，双耳闭塞无法听闻。
薄厥的症状是：阳气因大怒而逆乱，导致形体之气隔绝，血液郁积于头部上方。
胀满、完谷不化的泄泻，寒热之邪不散，气机升降失常。
颓疝（睾丸肿痛）、心脏牵引性疼痛，寒气多向下坠，从而形成各种疝气。
蛊惑之病（此处指肾精亏损导致的虚损重症），肾气不足，冤热（郁热）急迫，白浊液体流出，身体跳动抽搐。
肾精不足，头部僵硬且视力模糊。
唾液粘稠如涕，怕风并伴有寒战，这称为劳风。
即使穿着厚衣棉絮，若营气虚弱而卫气实盛，称为肉苛（肌肤麻木不仁）。
心将寒气移传于肺，则发生肺消（一种以多饮多尿为特征的消渴病）。
热邪炽盛则阳络溢血，阳络溢血导致鼻衄（鼻出血）。
醉酒后行房事，耗竭真气并损伤肝脏，大量失血，月经量少甚至闭经，称为血枯。
蕴积的热邪郁结，产生各种风证。
寒、湿、风三种邪气混杂结合，形成各种痹证。
面色出现白色或黑色，这被称为色夭（脏腑精气衰败的面色）。
气血衰竭减少，使人懈怠无力。
腰部和股部疼痛发作，肿胀且二便不便，寒气内生导致濡泄（大便稀溏如水）。
简要叙述这些证候，不能全部列举。
Huangdi said: "One who is skilled in discussing the Way of Heaven must verify it in human beings. One who is skilled in discussing antiquity must align it with the present. One who is skilled in discussing humanity must reflect it upon oneself. If one is not confused by these principles, this is called 'Clarity' (Ming). I ask you, Master, that words can be understood, sights can be seen, and touch can be perceived. Now, regarding enlightenment and resolving confusion, may I hear your explanation?"
Qibo bowed his head and replied: "What Way do you inquire about? Heaven covers above, Earth supports below, all things are fully equipped, and nothing is more precious than humans. Humans are born from the Qi of Heaven and Earth, and their formation follows the laws of the Four Seasons. Rulers and officials govern the common people, desiring to preserve their physical forms and vital life. Although status differs between noble and base, the treasure of life is identical; loving life and hating death is the constant nature of the world. If a person falls ill, it is as urgent as rescuing from fire or drowning. Do not wait until pathogenic factors linger and deepen, penetrating into the bone marrow, for then treatment becomes difficult."
The presentation of Jian Jue (Frying Syncope) involves excessive mental labor causing Yang Qi to become agitated, leading to exhaustion of Jing Essence. Accumulating through summer, this results in blindness where vision is lost and deafness where hearing is blocked.
The presentation of Bo Jue (Thin Syncope) involves extreme anger causing Yang Qi to rebel, leading to the severance of Xing Qi (Form Qi) and blood stagnating at the upper body/head.
Distension and Sun Xie (undigested food diarrhea), with persistent cold-heat patterns and disrupted ascending-descending movement of Qi.
Tui Shan (testicular swelling/pain) and heart pulling pain, with cold sensation descending downward, forming various types of Hernia diseases.
Internal heat in the Heart causing pulling sensations, knotting of Yin and Yang, edema of the four limbs, and continuous hematochezia.
Gu disease (a severe deficiency condition often associated with parasitic or toxic accumulation), characterized by insufficiency of Kidney Qi, oppressive heat urgency, discharge of white turbid fluid, and jumping/twitching sensations.
Bladder dysfunction leads to San Jiao constraint resulting in enuresis. Insufficiency of Kidney Jing causes stiffness of the neck and dim vision.
Saliva resembling phlegm, aversion to wind, and chills constitute Lao Feng (Labor Wind). Even when wearing thick clothes, if Ying Qi is deficient and Wei Qi is excess, it is named Rou Ke (muscle numbness/atrophy).
If Cold transfers from the Heart to the Lung, Fei Xiao (Lung Consumption/Xiao Ke) occurs. If Cold transfers from the Lung to the Kidney, Yong Shui (Surging Water/edema) occurs. If Heat transfers from the Heart to the Lung, Ge Xiao (Diaphragmatic Consumption) occurs. If Heat transfers from the Gallbladder to the Brain, Bi Yuan (Nasal Sinusitis/Olfactory disorder) occurs. If Heat transfers from the Bladder to the Small Intestine, Kou Mi (Oral Ulceration/Mucosal erosion) occurs. If Heat transfers from the Large Intestine to the Stomach, it leads to rapid digestion and hunger after eating.
Excessive heat causes overflow of Yang Luo (Yang Collaterals); overflow of Yang Luo results in Nu Xue (epistaxis/nosebleed). Sexual intercourse while intoxicated exhausts Qi and damages the Liver, causing massive blood loss, scanty menstruation, or amenorrhea, named Xue Ku (Blood Dryness).
Accumulated heat and depression generate various Wind syndromes. The combination of Cold, Dampness, and Wind pathogens creates various Bi Syndromes (Obstruction syndromes). Flaccidity of Zong Jin (Major Tendons) manifests as Bai Yin (white discharge/slippage). Heat gathering at the stomach gate without dispersing causes Stomach Epigastric Abscess. White or black complexion indicates Se Tian (dull/discolored face indicating organ failure). Bitter taste with accumulated heat is named Dan Dan (Gallbladder Heat/Kidney Deficiency Syndrome). Kidney deficiency with internal depletion leads to Yin Fei (aphonia combined with flaccidity/paralysis). Exhaustion of Blood and Qi causes lethargy. Abdominal fullness and anorexia, with middle-jiao cold causing intestinal leakage, result in Tang Bian (loose stools). Pain in the waist and thighs, swelling, and difficulty in urination/defecation, with cold generating Ru Xie (watery diarrhea), are described here. This brief account does not cover all conditions.
