阳气上而不下曰痞。阴气下而不上。亦曰痞。阳气下而不上曰格。阴气上而不下。亦曰格。痞格者谓阴阳
不相从也。阳奔于上则燔。脾肺生其疽也。其色黄赤。皆起于阳极也。阴走于下则冰。肾肝生其厥也。其色
青黑。皆发于阴极也。疽为黄疽也。厥为寒厥也。由阴阳痞格不通而生焉。阳燔则治以水。阴厥则助以火。
乃阴阳相济之道耳。
人之寒热往来者。其病何也。此乃阴阳相胜也。阳不足则先寒后热。阴不足则先热后寒。又上盛则发热。

飞霜走雹，早晚昏暗，云雨飘洒，风露寒冷。应当热的时候不热，尚未寒冷却先冷。时令阴雨连绵，田野泉水涌出，山崩地裂，土壤毁坏，河水泛滥。
月亮晦暗、太阳昏沉，这是天地的阴厥（阴气逆乱）。突然失声、骤然发冷，全身拘急，四肢蜷缩，嘴唇发青，面色黑黯，眼睛直视，牙关紧闭，心腹胀满疼痛，头部和下巴颤动摇晃，腰脚沉重，言语不清，上吐下泻，身体左右侧麻木不仁，大小便通畅或异常，呕吐酸水，悲伤忧愁，喜怒无常的，这是人的阴厥。
阴厥的脉象，轻取（举）感觉弱，重按（按）感觉大的预后良好；轻取重按都摸不到脉搏的预后不良。全身冰冷，额头出汗不止的也预后不良。阴厥之病，超过三天就不要治疗了。
阳气向上运行而不能下行称为“痞”（痞塞不通）。阴气向下运行而不能上行，也称为“痞”。阳气向下运行而不能上行称为“格”（格拒排斥）。阴气向上运行而不能下行，也称为“格”。所谓痞格，是指阴阳之气不相顺从协调。阳气奔涌于上部则导致火热燔灼，脾肺会产生疽（一种深部的化脓性感染），颜色黄赤，这都是由阳极（阳气极盛）引起的。阴气游走于下部则导致冰冻寒冷，肾肝会产生厥（寒厥证），颜色青黑，这都是由阴极（阴气极盛）引起的。这里的“疽”指的是黄疽（黄疸类疾病），“厥”指的是寒厥。这是由于阴阳痞塞格拒、气机不通而产生的。阳气燔灼则用水来治疗，阴气厥冷则用火（温补法）来辅助，这是阴阳相互济助的道理。
人出现寒热往来的症状，是什么病呢？这是阴阳相互胜负的结果。阳气不足则先感到寒冷后发热，阴气不足则先感到发热后寒冷。又比如上部邪气盛则发热，下部邪气盛则发寒。皮肤寒冷且干燥的是阳气不足，皮肤发热且干燥的是阴气不足。皮肤寒冷且自觉寒冷的，是阴气盛；皮肤发热且自觉发热的，是阳气盛。发热在下部，是阴中之阳邪；发热在上部，是阳中之阳邪。寒冷起于上部，是阳中之阴邪；寒冷起于下部，是阴中之阴邪。寒冷而脸颊发红、多言的，是阳中之阴邪；发热而面色发青、多言的，是阴中之阳邪；寒冷而面色发青、多言的，是阴中之阴邪。如果患者不说话（神志昏迷或极度虚弱），则不可治。
属于“阴中之阴中”的情况，一生九死；属于“阳中之阳中”的情况，九生一死。阴病难治，阳病易医。诊察其脉象，脉数（快）出现在上部则是阳中之阳，脉数出现在下部则是阴中之阳，脉迟（慢）出现在上部则是阳中之阴，脉迟出现在下部则是阴中之阴。脉数在中部则是中焦有热，脉迟在中部则是中焦有寒。寒证用热法治疗，热证用寒法攻逐。逆顺的治疗法则，顺应天地规律，根本在于阴阳。天地是人的父母，阴阳是人的根本。没有不遵循天地阴阳规律的。顺应者生，违背者死。寒证再用寒药，热证再用热药，反而可能生机尚存（注：此处原文逻辑较复杂，通常指真寒假热或真热假寒需辨别，但直译为：寒之又寒，热之又热者生，意指若为真寒假热等特殊情况下的反治法，或者原文意指误治后的极端情况，此处依字面翻译）。《金匮要略大要论》说：夜间发作寒证的为顺，夜间发作发热的为逆；白天发作发热的为顺，白天发作发寒的为逆。顺逆的征兆，也在于审察明确。
Flying frost and rolling hail. Dimness at dawn and dusk. Clouds and rain drifting, wind and dew cold. When it should be hot, it is not hot; before it should be cold, it becomes cold. The seasonal climate is continuous heavy rain, springs emerge in fields, mountains collapse, the earth cracks, soil crumbles, and rivers overflow.
The moon is dark (on the last day of the lunar month), the sun is dim. This is the Yin Jue (Yin Reversal Syndrome) of Heaven and Earth. Sudden aphonia and abrupt chills, whole-body stiffness, limbs curled and contracted, cyanotic lips, blackish complexion, fixed gaze, clenched jaw, abdominal fullness and pain, trembling of the head and chin, heaviness in the waist and legs, slurred speech, vomiting and diarrhea, numbness on both sides of the body, normal or abnormal urination and defecation, regurgitation of sour fluid, sorrow and grief, unpredictable mood swings. This is the Yin Jue (Yin Reversal Syndrome) of humans.
The pulse of Yin Jue: if it feels weak upon light pressure (Ju) but large upon heavy pressure (An), the prognosis is good; if it is imperceptible under both light and heavy pressure, the prognosis is fatal. If the whole body is completely cold and sweat spontaneously flows from the forehead, this is also fatal. For Yin Jue disease, do not treat it after three days have passed.
When Yang Qi moves upward but cannot descend, it is called Pi (Obstruction/Stagnation). When Yin Qi moves downward but cannot ascend, it is also called Pi. When Yang Qi moves downward but cannot ascend, it is called Ge (Rejection/Blockage). When Yin Qi moves upward but cannot descend, it is also called Ge. "Pi and Ge" refer to the failure of Yin and Yang Qi to follow and coordinate with each other. When Yang rushes to the upper part, it causes burning heat, leading to Ju (deep-seated abscesses/carbuncles) in the Spleen and Lungs. The color is yellow-red, all arising from extreme Yang (Yang Excess). When Yin wanders to the lower part, it causes freezing cold, leading to Jue (Cold Reversal Syndrome) in the Kidneys and Liver. The color is blue-black, all arising from extreme Yin (Yin Excess). Here, "Ju" refers to Jaundice (specifically Yellow Jaundice), and "Jue" refers to Cold Jue. These arise from the obstruction and blockage of Yin and Yang Qi. Burning Yang is treated with Water (Cooling/Clearing methods); Cold Jue is assisted by Fire (Warming/Moxibustion methods). This is the way of mutual assistance between Yin and Yang.
What is the disease causing alternating chills and fever in humans? This is due to the mutual victory and defeat of Yin and Yang. If Yang is insufficient, there are chills first followed by fever; if Yin is insufficient, there is fever first followed by chills. Furthermore, excess in the Upper Jiao causes fever; excess in the Lower Jiao causes chills. Cold skin with dryness indicates insufficient Yang; hot skin with dryness indicates insufficient Yin. Cold skin with a sensation of cold indicates excess Yin; hot skin with a sensation of heat indicates excess Yang. Fever originating in the lower part is an Yang pathogen within Yin; fever originating in the upper part is an Yang pathogen within Yang. Cold originating in the upper part is a Yin pathogen within Yang; cold originating in the lower part is a Yin pathogen within Yin. Chills with red cheeks and excessive talking indicate a Yin pathogen within Yang; fever with a bluish complexion and excessive talking indicate an Yang pathogen within Yin; chills with a bluish complexion and excessive talking indicate a Yin pathogen within Yin. If the patient does not speak, it is untreatable.
In cases of "Yin within Yin," one survives out of ten; in cases of "Yang within Yang," nine survive out of ten. Yin diseases are difficult to treat; Yang diseases are easy to cure. Upon examining the pulse: rapid pulse in the upper position indicates Yang within Yang; rapid pulse in the lower position indicates Yang within Yin; slow pulse in the upper position indicates Yin within Yang; slow pulse in the lower position indicates Yin within Yin. Rapid pulse in the middle position indicates Heat in the Middle Jiao; slow pulse in the middle position indicates Cold in the Middle Jiao. Cold is treated with Heat methods; Heat is attacked with Cold methods. The principles of reversal and compliance follow Heaven and Earth, rooted in Yin and Yang. Heaven and Earth are the parents of humans; Yin and Yang are the root of humans. None exist without following the Yin and Yang of Heaven and Earth. Those who comply live; those who oppose die. [Note: The text states "Cold again with cold, heat again with heat results in life," which may refer to specific counter-treatment scenarios or extreme conditions where the true nature is revealed, though literally translated as applying the same nature]. The *Da Yao Lun* of the *Jin Gui* states: Chills occurring at night are compliant (Shun); fever occurring at night is opposing (Ni). Fever occurring during the day is compliant; chills occurring during the day are opposing. The signs of compliance and opposition must be carefully examined and clarified.
