患伤寒病，经过催吐或泻下治疗后，过了六七天病情仍未解除，热邪结聚在体内，表现为体表和内部都发热，经常感到怕风，极度口渴，舌面干燥且心烦意乱，想要喝几升水，应当用白虎加人参汤（Baihu Jia Renshen Tang, White Tiger Plus Ginseng Decoction）来主治。
以下三条。王叔和本在太阳篇中。今移置此。
下面这三条条文，在王叔和编次的《伤寒论》版本中原属于太阳病篇，现在将其移置到此处。
伤寒若下若吐后。至七八日不解。而燥渴转增者。邪气去太阳之经。而入阳明之腑也。阳明经为表。而腑为里。故曰热结在里。腑中之热。自内际外。为表里俱热。热盛于内。阴反居外。为时时恶风。而胃者。津液之原也。热盛而涸。则舌上干燥。故既以白虎除热。必加人参以生津。尚从善所谓邪热结而为实者。则无大渴。邪气散漫。熏蒸焦膈。故舌上干燥而烦。大渴欲饮水数升是也。是以白虎承气。并为阳明腑病之方。而承气苦寒。逐热荡实。为热而且实者设。白虎甘寒。逐热生津。为热而不实者设。乃阳明邪热入腑之两大法门也。故从太阳分出三条。并列于此云。
患伤寒病，经过泻下或催吐治疗后，到了七八天病情仍未解除，且燥热口渴症状加重，这是病邪离开了太阳经，进入阳明腑的缘故。阳明经主表，阳明腑主里，所以说热邪结聚在里。腑中的热邪由内向外蒸腾，导致表里都发热。热邪炽盛于体内，阴液反而被格拒于外，所以会经常感到怕风。胃是津液的源头，热邪炽盛耗伤津液，就会导致舌面干燥。因此，既然要用白虎汤清除热邪，就必须加入人参来滋生津液。尚从善曾说，如果是邪热结聚而成实证，就不会有严重的口渴；如果是邪气散漫，熏蒸胸膈，才会出现舌面干燥、心烦、极度口渴想喝几升水的症状。所以，白虎汤和承气汤，都是治疗阳明腑病的方剂。承气汤味苦性寒，旨在驱逐热邪、攻荡积滞，是为既有热邪又有积滞的实证所设；白虎汤味甘性寒，旨在驱逐热邪、滋生津液，是为只有热邪而无积滞的非实证所设。这是治疗阳明邪热传入腑证的两大主要法则。因此，将这三条从太阳病篇分出，并列在此处说明。
白虎加人参汤 方见太阳斡旋法。
白虎加人参汤（Baihu Jia Renshen Tang, White Tiger Plus Ginseng Decoction）的方剂组成，参见“太阳病斡旋法”章节。
伤寒无大热。口燥渴。心烦。背微恶寒者。白虎加人参汤主之。
患伤寒病，体表没有明显的大热，但口燥渴、心烦，背部微微怕冷，应当用白虎加人参汤（Baihu Jia Renshen Tang, White Tiger Plus Ginseng Decoction）来主治。
无大热。表无大热也。口燥渴心烦。里热极盛也。背微恶寒。与时时恶风同意。盖亦太阳经邪传入阳明胃腑。熏蒸焦膈之证。故宜白虎加人参。以彻热而生津也。
“无大热”，是指体表没有明显的大热。“口燥渴、心烦”，说明体内热邪极盛。“背部微微怕冷”，与前面提到的“经常怕风”意思相同。这大概也是太阳经的病邪传入阳明胃腑，熏蒸胸膈所致。因此适宜使用白虎加人参汤，以清彻热邪并滋生津液。
伤寒脉浮。发热无汗。其表不解者。不可与白虎汤。渴欲饮水。无表证者。白虎加人参汤主之。
患伤寒病，如果脉象浮，发热且无汗，表证尚未解除的，不可以给予白虎汤。如果口渴想喝水，且没有表证的，应当用白虎加人参汤（Baihu Jia Renshen Tang, White Tiger Plus Ginseng Decoction）来主治。
前二条既着白虎之用。此条复示白虎之戒。谓邪气虽入阳明之腑。而脉证犹带太阳之经者。则不可便与白虎汤。与之则适以留表邪。而伤胃气也。而又申之曰、渴欲饮水。无表证者。白虎加人参汤主之。其丁宁反复之意。可谓至矣。
前两条已经阐述了白虎汤的应用，这一条再次警示使用白虎汤的注意事项。意思是说，虽然病邪已经传入阳明腑，但如果脉象和证候仍带有太阳经的特征，就不可以轻易给予白虎汤。如果误用，反而会滞留表邪，损伤胃气。接着又强调说：口渴想喝水，且没有表证的，才用白虎加人参汤主治。这种叮咛反复的用意，可以说是非常周到了。
Shanghan disease. If after emesis or purgation, the condition remains unresolved after six or seven days, with heat accumulating in the interior, manifesting as fever both in the exterior and interior, occasional aversion to wind, severe thirst, dryness of the tongue accompanied by irritability, and a desire to drink several liters of water, Baihu Jia Renshen Tang (White Tiger Plus Ginseng Decoction) should be administered.
The following three clauses were originally located in the Taiyang Chapter in Wang Shuhe's edition. They are now relocated here.
After Shanghan disease is treated with purgation or emesis, if the condition remains unresolved after seven or eight days, and dryness and thirst intensify, it indicates that the pathogenic factor has left the Taiyang channel and entered the Yangming fu-organ. The Yangming channel governs the exterior, while its fu-organ governs the interior; hence, it is said that heat accumulates in the interior. The heat within the fu-organ steams outward from the inside, resulting in fever both in the exterior and interior. When heat is excessive in the interior, yin is repelled to the exterior, causing occasional aversion to wind. The stomach is the source of body fluids. When excessive heat depletes these fluids, the tongue becomes dry. Therefore, since Baizhu Tang is used to clear heat, Renshen (Ginseng Radix et Rhizoma) must be added to generate fluids. Shang Congshan stated that if evil heat accumulates to form excess patterns, there will not be severe thirst. However, when the pathogenic factor is diffuse and steams the diaphragm, it causes dryness of the tongue, irritability, and severe thirst with a desire to drink several liters of water. Thus, Baihu Tang and Chengqi Tang are both formulas for treating Yangming fu-diseases. Chengqi Tang is bitter and cold, aiming to purge heat and eliminate excess accumulation, designed for patterns characterized by both heat and excess. Baihu Tang is sweet and cold, aiming to purge heat and generate fluids, designed for patterns characterized by heat without excess. These constitute the two major approaches for treating evil heat entering the fu-organs in Yangming. Therefore, these three clauses are extracted from the Taiyang section and placed together here for explanation.
Baihu Jia Renshen Tang (White Tiger Plus Ginseng Decoction). See the formula in the "Taiyang Manipulation Method" section.
In Shanghan disease, if there is no significant external heat, but mouth dryness and thirst, irritability, and slight aversion to cold on the back are present, Baihu Jia Renshen Tang (White Tiger Plus Ginseng Decoction) should be administered.
"No significant external heat" refers to the absence of marked fever on the body surface. "Mouth dryness, thirst, and irritability" indicate extreme internal heat. "Slight aversion to cold on the back" shares the same meaning as "occasional aversion to wind." This likely represents a pattern where pathogenic factors from the Taiyang channel have transmitted into the Yangming stomach fu-organ, steaming the diaphragm. Therefore, Baihu Jia Renshen Tang is appropriate to thoroughly clear heat and generate fluids.
In Shanghan disease, if the pulse is floating, there is fever without sweating, and the exterior syndrome is not resolved, Baihu Tang should not be given. If there is thirst with a desire to drink water, and no exterior syndrome is present, Baihu Jia Renshen Tang (White Tiger Plus Ginseng Decoction) should be administered.
The previous two clauses illustrate the application of Baihu Tang. This clause reiterates the contraindications for using Baihu Tang. It states that although the pathogenic factor has entered the Yangming fu-organ, if the pulse and symptoms still carry characteristics of the Taiyang channel, Baihu Tang should not be hastily administered. Doing so would merely retain the exterior pathogen and damage stomach qi. It further emphasizes: if there is thirst with a desire to drink water and no exterior syndrome, Baihu Jia Renshen Tang (White Tiger Plus Ginseng Decoction) should be administered. This repeated caution demonstrates utmost thoroughness.
