有病温汗出，辄复热而脉躁疾，不为汗衰，狂言不能食，病名曰阴阳交，见三死而未见一生。
（寅申巳亥辰戌丑未年有此证。）温病得病，便短息微闷，神识惺惺，脉尺寸反者死。（子午卯酉
年有此证。）
凡温病患三二日，身热脉疾，头痛，食饮如故，脉直疾，八日死；四五日头痛脉疾，喜吐，脉
来细，十二日死，此病不疗；八九日脉不疾，身不痛，目不赤，色不变，而反利，脉来牒牒，按不
弹手指，时时大，心下硬，十七日死。（心下不硬者生。）
饮酒合阴阳复病必死，生 煮面酒，韭、蕈、鳝、 、豆粉，犬羊肉肠血、生果、油肥之类，
食之皆发热黄，下利不救。诸劳动皆致复，尚可治，女劳多死。
庞曰∶动脉见于关上下，无头尾，厥厥动摇，名曰动也。阳动则汗出，阴动则发热。关位占六
分，前三分为阳，后三分为阴。若当阳连寸动而阴静，法当有汗而解。《素问》云∶阳加于阴谓之
汗。当阴连尺动而阳静，则发热，《素问》云∶尺粗
为热中。若大汗后，形冷恶寒者，三焦伤也，此是死证。脉按之虚软，战汗而解；脉按之有力，躁
汗而解；脉虚微，必经汗吐下，无津液作汗，阴阳自和愈。
趺阳在足大指次指间，上行五寸，是足阳明胃脉也。（名曰冲阳穴也。）
少阴脉在足内踝后，跟骨上动脉陷中，是足少阴肾脉也。（名太溪穴。）
仲景云∶按寸不及尺，握手不及足。谓医者只凭尺寸，不诊冲阳、太溪也。
庞曰∶寸口脉浮大，浮为虚，医反下之，为责虚取实；大为无血，反饮冷水，令汗大出，为守
空迫血。致趺阳脉亦浮虚，虚寒相搏，则噎也；若趺阳脉不浮而但滑者，则胃寒而哕矣。
庞曰∶伏气之病，谓非时有暴寒而中人，伏毒瓦斯于少阴经，始虽不病，旬月乃发，便脉微弱，
法先喉痛似伤，次则下利。喉痛半夏桂枝甘草汤主之；下利有诸证，用通脉四逆汤主之。（方
在少阴证中。）此病三二日便瘥，古方谓肾伤寒是也。

庞曰∶君子春夏养阳，秋冬养阴，顺天地之刚柔也。谓时当温，必将理以凉；时当暑，必将理
以冷，凉冷合宜，不可太过，故能扶阴气以养阳气也。时当凉，必将理以温；时当寒，必将理以热，
温热合宜，不可太过，故能扶阳气以养阴气也。阴阳相养，则人气和平。有人好摄生者，盛暑亦复
衣避风，饮食必热，而成发黄脱血者多矣。盛寒之时，方宜暖，当服以凉药而成吐利腹痛者多矣。此
皆凭庸人妄传，以为实理，往往横夭而尚不觉知，深可伤也。此是平人将理之法，其有夙热痼冷者，
须当顺其性尔。
有一种温病，患者出汗后随即再次发热，且脉搏躁动急速，出汗并不能使脉象减缓，伴有胡言乱语、不能进食的症状，这种病名为“阴阳交”，表现为三种死证迹象而未见一种生证迹象。
（在寅、申、巳、亥、辰、戌、丑、未年份会出现此类证候。）温病发病时，若出现呼吸短促、轻微胸闷、神志尚清醒但脉象寸尺相反者，为死证。（在子、午、卯、酉年份会出现此类证候。）
凡是温病患者两三天后，身体发热、脉搏疾速、头痛，但饮食如常，若脉象直而疾速，八天后死亡；四五天后头痛、脉疾、喜欢呕吐，脉象细弱，十二天后死亡，此病难以治愈；八九天后脉象不疾速，身体不痛，眼睛不红，面色无变化，反而出现腹泻，脉象来势急促（牒牒），按压手指无弹性跳动，时而变大，心下部位坚硬，十七天后死亡。（若心下不坚硬者则生机尚存。）
饮酒导致阴阳失调而复发疾病必死无疑；食用煮面酒、韭菜、蘑菇、鳝鱼、豆粉、狗肉羊肉及肠血、生水果、油腻肥甘之类食物，食用后都会导致发热、发黄、腹泻不止而无法救治。各种劳累都会导致疾病复发，尚可治疗，但房劳过度多致死亡。
庞安石说：动脉出现在关部上下，没有头尾，厥厥动摇不定，称为“动”脉。阳动则出汗，阴动则发热。关部脉位占六分，前三分为阳，后三分为阴。如果阳气连于寸部而动而阴气静止，按照法度应当有汗而解。《素问》说：“阳加于阴谓之汗。”如果阴气连于尺部而动而阳气静止，则会发热，《素问》说：“尺部脉粗大为热中。”如果在大汗之后，出现形体寒冷、恶寒的症状，这是三焦受损，属于死证。脉象按之虚软，通过战栗出汗而解除病邪；脉象按之有力，通过躁动出汗而解除病邪；脉象虚微，必须经过发汗、催吐、泻下等治疗，若无津液化汗，需待阴阳自和而痊愈。
趺阳穴位于足大趾与次趾之间，上行五寸处，是足阳明胃经的脉动处。（名为冲阳穴。）
少阴脉位于足内踝后方，跟骨上方的动脉凹陷中，是足少阴肾经的脉动处。（名为太溪穴。）
张仲景说：“按寸口不及尺部，握手不及足。”意思是医生只凭寸口脉诊，而不诊察冲阳、太溪脉。
庞安石说：寸口脉浮大，浮表示虚证，医生反而用攻下法，这是责其虚而取其实（误治）；大表示无血，医生反而让患者喝冷水，令其大汗出，这是守着空虚而逼迫血液。这会导致趺阳脉也呈现浮虚，虚寒相搏结，则会出现噎膈；如果趺阳脉不浮而仅见滑象，则是胃寒而出现呃逆。
庞安石说：伏气病，是指非时令之时突然受寒邪中人，毒瓦斯潜伏于少阴经，起初虽不发病，经过旬月才发作，此时脉象微弱，法度上先出现咽喉疼痛似受伤症状，随后出现腹泻。咽喉疼痛用半夏桂枝甘草汤主治；腹泻有多种证候，用通脉四逆汤主治。（方剂在少阴证章节中。）此病两三天即可好转，古方称之为肾伤寒。

庞安石说：君子春夏保养阳气，秋冬保养阴气，顺应天地的刚柔特性。意思是当气候温暖时，调理宜用凉性方法；当气候暑热时，调理宜用冷性方法，凉冷适宜，不可太过，所以能扶持阴气以滋养阳气。当气候凉爽时，调理宜用温性方法；当气候寒冷时，调理宜用热性方法，温热适宜，不可太过，所以能扶持阳气以滋养阴气。阴阳相互滋养，人气才能平和。有人喜好养生，盛暑时节也穿衣避风，饮食必热，因而导致发黄、脱血的很多。盛寒之时，本应保暖，却服用凉药，因而导致呕吐、腹泻、腹痛的很多。这些都是凭借庸人妄传，以为是真理，往往导致横死而尚不觉悟，实在令人悲伤。这是普通人调养的方法，那些素有积热或顽固寒症的人，必须顺应其本性来处理。
There is a type of warm disease where the patient sweats, then immediately fever returns with a restless and rapid pulse. The sweating does not alleviate the pulse's intensity. Accompanied by delirious speech and inability to eat, this disease is named "Yin-Jiao" (Intersection of Yin and Yang). It presents three signs of death without showing any sign of life.
(In years of Yin, Shen, Si, Hai, Chen, Xu, Chou, and Wei, this syndrome occurs.) In warm diseases, if upon onset there is shortness of breath, slight chest oppression, consciousness remains relatively clear, but the pulse at Cun and Chi positions is reversed, it indicates death.
(In years of Zi, Wu, Mao, and You, this syndrome occurs.)
Generally, for warm disease patients after two or three days, if there is body heat, rapid pulse, headache, but normal diet, and the pulse is straight and rapid, death occurs in eight days; if after four or five days there is headache, rapid pulse, tendency to vomit, and the pulse is fine, death occurs in twelve days; this disease is difficult to treat. If after eight or nine days the pulse is not rapid, the body is not painful, eyes are not red, complexion unchanged, but diarrhea occurs instead, and the pulse comes rapidly (Die-Die), pressing on fingers yields no elastic rebound, occasionally becoming large, with hardness below the heart, death occurs in seventeen days. (If there is no hardness below the heart, survival is possible.)
Drinking alcohol causing Yin-Yang disharmony and relapse leads to certain death; consuming cooked noodle wine, leeks, mushrooms, eels, bean powder, dog meat, mutton, intestines, blood, raw fruits, oily and fatty foods will all cause fever, jaundice, and unrecoverable diarrhea. Various forms of labor can cause relapse, which may still be treatable, but sexual exhaustion often leads to death.
Pang Anshi said: The Dong Mai (Moving Pulse) appears above and below the Guan position, lacking head and tail, trembling violently, named "Dong". Yang movement causes sweating; Yin movement causes fever. The Guan position occupies six fen; the front three fen are Yang, the rear three fen are Yin. If Yang connects to Cun and moves while Yin remains static, according to the method, there should be sweating leading to resolution. Su Wen states: "Yang added to Yin is called sweat." If Yin connects to Chi and moves while Yang remains static, fever occurs; Su Wen states: "Roughness at Chi indicates internal heat." If after profuse sweating, the form is cold and aversion to cold exists, this is damage to the San Jiao (Triple Burner), indicating a fatal condition. If the pulse is soft and empty upon pressure, resolution occurs through chills and sweating; if the pulse is forceful upon pressure, resolution occurs through restless sweating; if the pulse is extremely weak, one must undergo sweating, vomiting, or purging therapies. Without body fluids to generate sweat, recovery depends on the self-harmonization of Yin and Yang.
Fuyang is located between the big toe and the second toe, ascending five cun, representing the Foot-Yangming Stomach Meridian pulse point. (Named Chongyang Acupoint.)
Shaoyin pulse is located behind the medial malleolus of the foot, in the depression of the arterial pulse above the calcaneus, representing the Foot-Shaoyin Kidney Meridian pulse point. (Named Taixi Acupoint.)
Zhang Zhongjing said: "Pressing Cun does not reach Chi, holding the hand does not reach the feet." This means physicians rely solely on Cun Kou pulse diagnosis and do not examine Chongyang and Taixi pulses.
Pang Anshi said: Cun Kou pulse floating and large; floating indicates deficiency. If the physician incorrectly uses purgation, it is blaming deficiency while seeking excess (mismanagement); large indicates lack of blood. If the physician gives cold water to induce profuse sweating, it is guarding emptiness while forcing blood. This causes Fuyang pulse to also become floating and empty. Empty cold struggling together results in dysphagia; if Fuyang pulse is not floating but merely slippery, it indicates stomach cold resulting in hiccups.
Pang Anshi said: Fu Qi Bing (Disease of Latent Pathogenic Qi) refers to sudden cold pathogen attacking the person out of season, with toxic qi lying latent in the Shaoyin Meridian. Initially asymptomatic, it manifests after ten days or a month. The pulse becomes weak. According to the method, throat pain resembling injury appears first, followed by diarrhea. Throat pain is treated primarily with Banxia Guizhi Gancao Tang (Pinellia, Cinnamon Twig, and Licorice Decoction); diarrhea with various syndromes is treated primarily with Tongmai Sini Tang (Unblocking the Pulse and Reversing Collapse Decoction). (The formula is found in the Shaoyin Syndrome section.) This disease improves within two or three days; ancient texts refer to this as Kidney Shanghan (Cold Damage to the Kidney).
Herbs: Banxia (Pinelliae Rhizoma), Guizhi (Cinnamomi Ramulus), Gancao (Glycyrrhizae Radix et Rhizoma), Shengjiang (Zingiberis Rhizoma Recens) (each 1 liang).
Chop them, add three sheng of water, boil to obtain one sheng. Take one cup per dose, sip slowly.
Pang Anshi said: Gentlemen nourish Yang in Spring and Summer, and nourish Yin in Autumn and Winter, conforming to the rigidity and flexibility of Heaven and Earth. When the climate is warm, regulation should employ cooling methods; when the climate is hot, regulation should employ cold methods. Cooling and cold must be appropriate, not excessive, thus supporting Yin Qi to nourish Yang Qi. When the climate is cool, regulation should employ warming methods; when the climate is cold, regulation should employ hot methods. Warming and hot must be appropriate, not excessive, thus supporting Yang Qi to nourish Yin Qi. When Yin and Yang mutually nourish, human Qi remains peaceful. Some who favor health preservation wear clothes to avoid wind even in intense summer heat and consume only hot food, leading to many cases of jaundice and blood depletion. During intense winter cold, when warmth is suitable, taking cold medicines leads to many cases of vomiting, diarrhea, and abdominal pain. These stem from vulgar rumors mistakenly believed as truth, often leading to premature death without realization, which is deeply sorrowful. This is the method for ordinary people to regulate their lives. However, those with chronic heat or entrenched cold must follow their specific nature.
