脉象按之来势缓慢，且偶尔出现一次停顿后再次跳动，这叫做“结”脉。另一种情况是脉搏跳动时突然中止，随后快速跳动几下中又有一个回返的搏动，这也叫做“结”脉，属于阴证。
脉搏跳动时突然中止，不能自行恢复，因而再次跳动，这叫做“代”脉，也属于阴证。出现这种脉象的人，病情一定难以治疗。
脉搏跳动较快，偶尔出现一次停顿后再次跳动，这叫做“促”脉；脉搏跳动缓慢，偶尔出现一次停顿后再次跳动，这叫做“结”脉。“结”脉是因为邪气结滞，导致脉气运行不利所致。另外，“结”脉与“代”脉相似但实质不同。“结”脉停止后立即恢复，不失节律，只是稍微迟缓一些；“代”脉停止后不能立即恢复，中断后再跳动，有此处断绝彼处接续的意思，所以称为“代”。两者都称为“阴”，是因为结脉和代脉都属于阴脉，所以称之为“结阴”和“代阴”。凡是疾病出现这种脉象的，如果用攻法，邪气未必能去除而正气反而受损；如果用补法，正气未得益处而邪气反而滞留，所以说难以治疗。张仲景针对上述条文中提到的结脉和代脉，详细描述了它们的形态特征如此。
以上都是太阳病的权变治法。所谓权变，是指虽然有汗证的指征，但不能直接使用发汗药。其中的方法有的取小汗，有的等待其自解，有的兼用清热，有的兼用消饮，有的先救里虚，有的建立中气，有的滋养营卫，种种方法各不相同。世道日益衰败，人心不如古时淳朴，凡所患的疾病，大多兼夹其他证候。学习中医的人对这些变法，尤其应当留意，所以特别归类列于此。共有二十三条。
太阳病，初次服用桂枝汤后，反而出现烦躁不解的症状，应先针刺风池穴、风府穴，然后再给予桂枝汤，病就会痊愈。
太阳病使用桂枝汤，从法度上讲是正确的。然而初次服药后，反而加重了烦热而不解，这是因为阳邪痹阻于阳分而不能散去。风池穴和风府穴是阳维脉的交会穴。阳维脉维系着诸阳经，针刺它们可以通阳散痹。痹阻通畅后，再给予桂枝汤取汗，病就会痊愈。这是张仲景治法中的治法。
服用桂枝汤后，大汗出，脉象洪大，仍按前法给予桂枝汤。如果病人症状像疟疾一样，一天发作两次，出汗后必定痊愈，适宜用桂枝二麻黄一汤。
服用桂枝汤后，虽然大汗出但邪气未去，这就是所谓的“如水淋漓，病必不除”。如果脉象洪大，说明邪气仍然很盛，所以适宜再次给予桂枝汤取汗。所谓“如前法”，是指喝热稀粥、温覆取汗的方法。如果病人的病症像疟疾，一天发作两次，这是正气内部战胜邪气、邪气欲退的征兆。假如因此出汗，邪气必然从表而解。但这不能用重剂发汗，桂枝二麻黄一汤既能扶助正气又兼散邪气，而且缩小了剂量，是太阳病发汗的轻剂。
桂枝二麻黄一汤方（条文论述在后面）
桂枝（去皮一两十七铢） 大枣（五枚掰开） 炙甘草 芍药 生姜（各一两六铢） 麻黄（十六铢去节） 杏仁（十六个去皮尖）
以上七味药，用水五升，先煮麻黄一二沸，去掉上面的浮沫，加入其他药物，煮取二升，去渣，温服一升，每天服两次。
服用桂枝汤后，大汗出之后，出现严重烦躁口渴不解，脉象洪大的，用白虎加人参汤主治。
服用桂枝汤后，大汗出，脉象洪大，与上一条相同。但出现严重烦躁口渴不解，说明邪气已由表入里，不在太阳经，而是进入了阳明腑。阳明是两阳交汇之处，也是津液之腑。邪气进入其中，足以增加热气并耗伤津液，所以出现严重烦躁口渴不解。方中使用石膏，味辛甘性大寒，直清胃热作为君药，并用知母的咸寒作为佐药。用人参、甘草、粳米的甘味，用来补救津液的亏损，同时也制约石膏的猛烈。叫它“白虎”，大概是取金气彻热的意思。
白虎加人参汤方
人参（三两） 知母（六两） 甘草（二两） 粳米（六合） 石膏（一斤打碎）
以上五味药，用水一斗，煮到米熟汤成，去渣，温服一升，每天服三次。
服用桂枝汤，或者经过攻下治疗后，仍然头项强痛，发热如羽毛覆盖般轻微发热，无汗，心下部满闷微痛，小便不利的，用桂枝去桂加茯苓白术汤主治。头项强痛，发热如羽毛覆盖般轻微发热，无汗，是邪气在表。心下部满闷微痛，是水饮停留在里。这是表间的邪气与心下的水饮相互结合而不解，所以发汗不能从表出，攻下不能从下出。表邪挟带水饮的，不可单纯攻表，必须治疗水饮然后表邪才可解除。桂枝汤去掉桂枝加上茯苓、白术，是不想发散表邪，而只驱逐里的水饮。水饮去除后，不仅满痛消除，而且表邪失去依附，也会自然解除。
桂枝去桂加茯苓白术汤方
在桂枝汤中去掉桂枝，加入茯苓、白术各三两，其余按照前面的方法煎煮服用。小便利则痊愈。
伤寒脉浮，自汗出，小便频数，心烦，轻微恶寒，脚部拘挛急迫，反而给予桂枝汤想要攻表，这是误治。得到这个结果后出现四肢厥冷，咽喉干燥，烦躁吐逆的，制作甘草干姜汤给予服用，以恢复阳气。如果四肢厥冷好转、足部变暖，再制作芍药甘草汤给予服用，脚部就能伸直。如果胃气不和，出现谵语的，少量给予调胃承气汤。如果再次重发汗，又加上烧针治疗的，用四逆汤主治。
脉浮，自汗出，轻微恶寒，虽然是感受寒邪但表不实，是桂枝汤证。然而小便频数，心烦，脚部拘挛急迫，则是阴虚而里有热。这时应当用甘辛药攻表，用甘寒药顾护里气，却反而给予桂枝汤，治表而遗漏了里，难怪得到这个结果后就出现四肢厥冷。咽喉干燥，烦躁吐逆，都是阴虚阳逆的表现。如果不是用温药徒然攻表，怎么会到这一步呢？既然下部阴虚，上部阳气上逆，那么必须先恢复阳气然后再恢复阴气。所以制作甘草干姜汤，这是甘辛复阳的药剂。阳气恢复则厥冷好转而足部变暖。再制作芍药甘草汤，这是甘酸复阴的药剂。阴气生成则双脚自然伸直。阴阳既已恢复，如果胃气仍有不和，因而出现谵语的，则少量给予调胃承气汤以调和胃气。胃气和顺则谵语停止。大概甘草、干姜固然足以挽救虚阳的上逆，但也可能损伤胃气的和谐。这种咸寒调胃的方法，不得不在阴阳既复之后进行斡旋。如果重发汗，又加上烧针，这是逆上加逆，其厥逆的现象，一定比之前更严重，而补救的方法，一定不是甘草、干姜所能胜任的了。四逆汤味甘辛性大热，是恢复阳气的重大药物。这一条前后用药，温凉补泻，绝不相谋，却恰好互相济助，不是造诣深厚、自有定见的人，怎么能达到这种境界。
甘草干姜汤方
甘草（四两炙） 干姜（二两）
以上两味药，切碎，用水三升，煮取一升五合，去渣，分两次温服。
芍药甘草汤方
芍药（四两） 甘草（四两炙）
以上两味药，用水三升，煮取一升五合，去渣，分两次温服。
问：病症像阳旦证（即桂枝汤证），按照法治它反而加重，出现四肢厥冷，咽喉干燥，两小腿拘挛急迫并且谵语。老师说半夜手足应当变暖，双脚应当伸直，后来果然像老师所说。怎么知道的？答：寸口脉浮而大，浮则为风邪，大则为虚。风邪则产生微热，虚则两小腿拘挛。病症像桂枝汤证，因此在其中加入附子，增加桂枝令其出汗。附子温经，是因为亡阳的缘故。出现四肢厥冷，咽喉干燥，烦躁，阳明内结，谵语烦乱，再饮用甘草干姜汤，夜半阳气回归，两足应当发热，小腿尚且轻微拘挛，再给予芍药甘草汤，然后小腿才能伸直。用承气汤轻微通便则停止谵语。所以知道病可以痊愈。
这就是上一条的意思，而设为问答，以阐明为什么加重以及为什么痊愈的原因。然而中间的语意非常没有条理，这难道是后人添加的文字吗？古人读《考工记》说它不像《周官》，我对于这一条也是如此看法。成无己说：阳旦是桂枝汤的别名。
The pulse, when pressed, comes slowly and occasionally stops before resuming. This is called the *Jie* (Knotted) pulse. Another case is where the pulse movement suddenly stops, then resumes with a few rapid beats followed by a return beat. This is also called the *Jie* (Knotted) pulse, indicating a Yin pattern.
When the pulse movement suddenly stops and cannot resume on its own, but instead resumes after a pause, this is called the *Dai* (Intermittent) pulse, which is also a Yin pattern. Patients presenting with this pulse will certainly be difficult to treat.
When the pulse beats rapidly and occasionally stops before resuming, it is called the *Cu* (Surging) pulse; when the pulse beats slowly and occasionally stops before resuming, it is called the *Jie* (Knotted) pulse. The *Jie* pulse occurs because pathogenic factors are knotted and stagnant, causing impediment in the flow of the pulse qi. Furthermore, although the *Jie* and *Dai* pulses appear similar, they are fundamentally different. The *Jie* pulse stops and immediately returns, maintaining its rhythm, merely being slightly slower. The *Dai* pulse stops and does not immediately return; after the interruption, it resumes, implying a sense of one area ceasing while another takes over, hence named *Dai*. Both are termed "Yin" because both *Jie* and *Dai* pulses belong to Yin categories, thus referred to as *Jie Yin* and *Dai Yin*. For any disease presenting with these pulses, if treated with purgation, the pathogen may not be expelled while healthy qi is further damaged; if treated with tonification, healthy qi gains no benefit while the pathogen becomes more stagnant. Therefore, it is said to be difficult to treat. Zhang Zhongjing, addressing the *Jie* and *Dai* pulses mentioned in the preceding clause, details their characteristics as follows.
The above all describe the adaptive methods for *Taiyang* (Greater Yang) disease. Adaptive methods refer to situations where, although indications for sweating exist, diaphoretic herbs cannot be used directly. These methods include inducing slight sweating, waiting for spontaneous resolution, combining heat-clearing, combining fluid-resolving, first rescuing interior deficiency, establishing Middle Qi, or nourishing Ying and Wei. The approaches vary greatly. As times decline and human nature becomes less pure than in antiquity, diseases often present with complex syndromes. Students should pay special attention to these adaptive methods, so they are specifically categorized here. There are twenty-three clauses in total.
In *Taiyang* disease, if after the initial dose of *Guizhi Tang* (Cinnamon Twig Decoction), vexation worsens without relief, one should first needle the Fengchi (GB20) and Fengfu (GV16) acupoints, then administer *Guizhi Tang*, after which the patient will recover.
Administering *Guizhi Tang* for *Taiyang* disease is correct according to the principles. However, if after the initial dose, vexation and heat increase without resolution, it is because Yang pathogenic factors are obstructed in the Yang aspect and cannot disperse. Fengchi and Fengfu are intersection points of the Yangwei Vessel. The Yangwei Vessel connects all Yang vessels; needling them unblocks Yang obstruction. Once the obstruction is cleared, administering *Guizhi Tang* to induce sweating will result in recovery. This is a method within Zhang Zhongjing's methods.
After taking *Guizhi Tang*, if profuse sweating occurs and the pulse is洪大 (Hongda, Great/Vigorous), administer *Guizhi Tang* again using the previous method. If the condition resembles malaria, occurring twice a day, sweating will lead to resolution; *Guizhi Er Mahuang Yi Tang* (Two Parts Cinnamon Twig and One Part Ephedra Decoction) is appropriate.
After taking *Guizhi Tang*, if profuse sweating occurs but the pathogen remains—described as "sweating like dripping water, yet the disease is not removed"—and the pulse is Hongda, the pathogen is still severe. Thus, it is suitable to give *Guizhi Tang* again to induce sweating. The "previous method" refers to drinking hot millet gruel and covering warmly to induce sweating. If the patient's symptoms resemble malaria, occurring twice daily, this indicates that healthy Qi has gained internal superiority and the pathogen is retreating. If sweating ensues, the pathogen will likely resolve from the exterior. However, heavy diaphoretic agents should not be used. *Guizhi Er Mahuang Yi Tang* assists healthy Qi while dispersing pathogens, with a reduced dosage, making it a mild diaphoretic formula for *Taiyang* disease.
Formula: Guizhi Er Mahuang Yi Tang (Discussion in subsequent clauses)
Guizhi (Cortex Cinnamomi, peeled, 1 liang 17 zhu) Dazao (Fructus Jujubae, 5 pieces, split) Zhi Gancao (Radix Glycyrrhizae Preparata) Shaoyao (Radix Paeoniae Alba) Shengjiang (Rhizoma Zingiberis Recens, each 1 liang 6 zhu) Mahuang (Herba Ephedrae, 16 zhu, nodes removed) Xingren (Semen Armeniacae Amarum, 16 pieces, skin and tips removed)
These seven ingredients are boiled in five sheng of water. First, boil Mahuang for one or two boils, remove the foam on top, then add the remaining herbs. Boil until two sheng remain, strain, and take one sheng warm. Administer twice daily.
After taking *Guizhi Tang*, if following profuse sweating, severe vexation and thirst persist without relief, and the pulse is Hongda, *Baitu Jia Renshen Tang* (White Tiger Plus Ginseng Decoction) is the primary treatment.
After taking *Guizhi Tang*, profuse sweating occurs, and the pulse is Hongda, identical to the previous clause. However, severe vexation and thirst without relief indicate that the pathogen has moved from the exterior to the interior, leaving the *Taiyang* meridian and entering the Yangming Fu organs. Yangming is the intersection of two Yangs and the Fu organ of fluids. Pathogens entering here increase heat and consume fluids, causing severe vexation and thirst. The formula uses Shigao (Gypsum Fibrosum), pungent, sweet, and very cold, to directly clear Stomach heat as the Sovereign herb, assisted by Zhimu (Rhizoma Anemarrhenae), salty and cold. The sweetness of Renshen (Radix Ginseng), Gancao (Radix Glycyrrhizae), and Jingmi (Oryza Sativa) saves fluid deficiency and moderates the harshness of Shigao. It is named "White Tiger" (Baitu), likely referring to the metal element's property of clearing heat.
Formula: Baitu Jia Renshen Tang
Renshen (Radix Ginseng, 3 liang) Zhimu (Rhizoma Anemarrhenae, 6 liang) Gancao (Radix Glycyrrhizae, 2 liang) Jingmi (Oryza Sativa, 6 he) Shigao (Gypsum Fibrosum, 1 jin, crushed)
These five ingredients are boiled in ten sheng of water until the rice is cooked and the decoction is ready. Strain and take one sheng warm, three times daily.
After taking *Guizhi Tang*, or after purgation, if there is still stiffness and pain in the head and neck, mild fever (like feathers covering), anhidrosis, fullness and mild pain in the epigastrium, and dysuria, *Guizhi Qu Guijia Fuling Baizhu Tang* (Cinnamon Twig Decoction minus Cinnamon Twig plus Poria and Atractylodes Macrocephala Decoction) is the primary treatment. Stiffness and pain in the head and neck, mild fever, and anhidrosis indicate pathogen in the exterior. Fullness and mild pain in the epigastrium indicate fluid retention in the interior. The exterior pathogen and interior fluid retention are interdependent and unresolved. Therefore, diaphoresis fails to expel from the exterior, and purgation fails to expel from the interior. When exterior pathogen carries fluid retention, one must not attack the exterior alone; treating the fluid retention allows the exterior to resolve. Removing GuiZhi from *Guizhi Tang* and adding Fuling (Poria) and Baizhu (Atractylodis Macrocephalae Rhizoma) avoids dispersing exterior pathogens and focuses on draining interior fluids. Once fluids are drained, fullness and pain cease, and the exterior pathogen, losing its attachment, resolves spontaneously.
Formula: Guizhi Qu Guijia Fuling Baizhu Tang
Remove GuiZhi from *Guizhi Tang*, add Fuling and Baizhu, each 3 liang. Prepare and administer according to the previous method. Recovery occurs when urination becomes normal.
In Shanghan (Cold Damage), if the pulse is floating, there is spontaneous sweating, frequent urination, vexation, mild aversion to cold, and cramping of the feet, administering *Guizhi Tang* to attack the exterior is an error. This mistake leads to cold limbs (Jue), dry throat, vexation, and vomiting. In such cases, prepare *Gancao Ganjiang Tang* (Licorice and Dried Ginger Decoction) to restore Yang Qi. If cold limbs resolve and feet become warm, prepare *Shaoyao Gancao Tang* (Peony and Licorice Decoction); the feet will extend. If Stomach Qi is disharmonious leading to delirium, administer a small amount of *Tiaowei Chengqi Tang* (Regulate the Stomach and Direct Downward Decoction). If excessive sweating was performed and moxibustion with burning needles was added, *Sini Tang* (Frigid Extremities Decoction) is the primary treatment.
Floating pulse, spontaneous sweating, and mild aversion to cold indicate that although affected by cold, the exterior is not solid, fitting the *Guizhi Tang* syndrome. However, frequent urination, vexation, and foot cramping indicate Yin deficiency with interior heat. One should use pungent-sweet herbs to attack the exterior and sweet-cold herbs to protect the interior. Instead, *Guizhi Tang* was given, treating the exterior while neglecting the interior, hence the resulting cold limbs. Dry throat, vexation, and vomiting are signs of Yin deficiency and Yang rebellion. Had warm herbs not been used to blindly attack the exterior, how could it have reached this state? Since there is Yin deficiency below and Yang rebellion above, Yang Qi must be restored first, then Yin Qi. Thus, *Gancao Ganjiang Tang* (pungent-sweet to restore Yang) is prepared. Restoration of Yang resolves cold limbs and warms the feet. Then, *Shaoyao Gancao Tang* (sweet-sour to restore Yin) is prepared. Generation of Yin allows the feet to extend naturally. After Yin and Yang are restored, if Stomach Qi remains disharmonious causing delirium, a small amount of *Tiaowei Chengqi Tang* harmonizes the Stomach. Harmonized Stomach Qi stops delirium. While Gancao and Ganjiang save rebellious deficient Yang, they may also damage Stomach harmony. Therefore, the salty-cold method of regulating the Stomach is necessary after Yin and Yang are restored. If excessive sweating and burning needles were used, it is error upon error; the cold limb phenomenon would be worse, and *Gancao Ganjiang Tang* would be insufficient. *Sini Tang*, pungent, sweet, and very hot, is a major medicine for restoring Yang Qi. The medications used before and after this clause, warming/cooling/tonifying/purging, seem unrelated yet complement each other perfectly. Only those with profound attainment and firm convictions could achieve this.
Formula: Gancao Ganjiang Tang
Gancao (Radix Glycyrrhizae, prepared, 4 liang) Ganjiang (Rhizoma Zingiberis Secatus, 2 liang)
Chop these two ingredients, boil in three sheng of water until one sheng five he remains. Strain and divide into two warm doses.
Formula: Shaoyao Gancao Tang
Shaoyao (Radix Paeoniae Alba, 4 liang) Gancao (Radix Glycyrrhizae, prepared, 4 liang)
Boil these two ingredients in three sheng of water until one sheng five he remains. Strain and divide into two warm doses.
Question: The symptoms resemble Yangdan syndrome. Following standard treatment, the condition worsened, leading to cold limbs, dry throat, calf cramping, and delirium. The Master said that at midnight, the hands and feet would warm, and the legs would extend. Later, this happened as predicted. How did you know? Answer: The Cun Kou pulse is floating and large. Floating indicates Wind; Large indicates Deficiency. Wind generates mild heat; Deficiency causes calf cramping. The symptoms resemble *Guizhi Tang* syndrome, so Fuzi (Radix Aconiti Lateralis Preparata) was added, and GuiZhi was increased to induce sweating. Fuzi warms the meridians due to Yang collapse. Cold limbs, dry throat, vexation, Yangming internal knotting, and delirious confusion occurred. Drinking *Gancao Ganjiang Tang* again, at midnight Yang Qi returns, and the feet become warm. With calves still slightly cramped, administering *Shaoyao Gancao Tang* allows the calves to extend. Using *Chengqi Tang* to cause slight stooling stops the delirium. Thus, we know the disease can be cured.
This clause reiterates the meaning of the previous one, using a Q&A format to explain why the condition worsened and why it recovered. However, the logic in between is disjointed; could this be text added by later generations? Ancients noted that the *Kaogong Ji* differs from the *Zhou Li*; I hold a similar view regarding this clause. Cheng Wuji states: Yangdan is an alias for *Guizhi Tang*.
