按以上诸证，均系表证未解，而里证或有积水，或有停痰，或有宿食，或有蓄热，表实而里亦实，故以表
里俱实证统之。
五苓散
猪苓（十八铢） 泽泻（一两六钱） 白术（十八铢） 桂枝（半两） 茯苓（十八铢）
（注∶一两二十四铢，十八铢即七钱五分。） 共为末，以白饮和服，三钱，日三服，多饮暖水，汗出愈。

土而生津，二苓、泽泻行水而泄湿也。
茯苓甘草汤
茯苓（二钱） 桂枝（二钱） 甘草（二钱） 生姜（三钱） 水煎服。按不渴者，湿

中风病出现发热，经过六七天病情没有缓解且感到烦闷，既有表证又有里证，口渴想喝水，但水喝进去就吐出来，这种情况叫做“水逆”。主治方剂是五苓散。
太阳病，经过发汗治疗后，大汗淋漓，导致胃中干燥，患者烦躁不安无法入睡，想要喝水时，应少量多次给予饮水，使胃气调和即可痊愈。如果脉象浮，小便不通利，有轻微发热且极度口渴的，主治方剂是五苓汤（即五苓散）。
原本因为误用泻下法治疗，导致心下部痞塞胀满，给予泻心汤后，痞塞症状仍未解除。如果患者口渴且口中烦躁，小便不利，主治方剂是五苓汤。
太阳病，寸脉缓、关脉浮、尺脉弱，患者发热出汗，又怕冷，不呕吐，只是心下部痞塞，这是因为医生误用了泻下法所致。如果没有误用泻下法，患者不怕冷而口渴的，这是病邪转属阳明经的表现。
小便频数的，大便必然干硬，即使十天不大便，也没有痛苦的感觉。如果口渴想喝水，少量给予饮水，只需按照正确的方法救治即可。对于口渴者，适宜使用五苓散。
伤寒病，出汗后出现口渴的，主治方剂是五苓散；不出渴的，主治方剂是茯苓甘草汤。
伤寒病出现四肢厥冷且心下部悸动的，应当先治疗水饮，适宜给予茯苓甘草汤。
太阳病经过泻下治疗后出现轻微气喘的，是因为表证未解，主治方剂是桂枝加厚朴杏子汤。
原本患太阳病，医生反而误用泻下法，导致腹部胀满、大实疼痛的，主治方剂是桂枝加大黄汤。
伤寒表证未解，心下有停饮，出现干呕、发热且咳嗽，或者口渴，或者腹泻，或者嗳气，或者小便不利、少腹胀满，或者气喘的，主治方剂是小青龙汤。
伤寒病，心下有停饮，咳嗽且轻微气喘，发热但不口渴的，主治方剂是小青龙汤。
服用小青龙汤后出现口渴的，这是寒邪已去、病情即将解除的表现。
伤寒瘀滞的热邪在体内，身体必然发黄，主治方剂是麻黄连翘赤小豆汤。
太阳经与阳明经合病，不下利但呕吐的，主治方剂是葛根加半夏汤。
伤寒发热，出汗后热势不解，心下部痞塞坚硬，呕吐且伴有腹泻的，主治方剂是大柴胡汤。
太阳病，病程超过十余日，医生反而反复使用泻下法，过了四五天后，如果柴胡证仍然存在，先给予小柴胡汤；如果呕吐不止，心下部拘急不适，心中郁郁微烦，说明病邪未解，此时使用大柴胡汤泻下则能痊愈。
伤寒十余日，热邪结聚在体内，同时又有往来寒热的症状，给予大柴胡汤。
伤寒后，脉象沉实的，属于内实证，应当用泻下法治疗，适宜使用大柴胡汤。
伤寒十三天未解，胸胁胀满且呕吐，每天傍晚定时发热，随后出现轻微腹泻，这原本是柴胡证，误用泻下法后不应腹泻却出现了腹泻，可知是医生使用了丸药攻下，这不是正确的治法。傍晚潮热说明里有实邪，先宜使用大柴胡汤以解除表邪，随后使用柴胡加芒硝汤治疗。
综上所述，以上各种证候，均属于表证未解，而里证或有积水，或有停痰，或有宿食，或有蓄热，表实而里亦实，因此统称为“表里俱实证”。

Taiyang disease presenting with fever, which persists for six or seven days without resolution accompanied by irritability, exhibits both exterior and interior syndromes. The patient feels thirsty and desires to drink water, but vomits immediately after swallowing it. This condition is named "Water Reversal" (Shui Ni). It is primarily treated with Wuling San (Five-Ingredient Powder with Poria).
In Taiyang disease, after sweating therapy, profuse sweating occurs, leading to dryness in the Stomach. The patient experiences restlessness and insomnia. If they desire water, provide it in small amounts frequently. Recovery occurs when the Stomach Qi harmonizes. If the pulse is floating, urination is difficult, there is slight heat, and extreme thirst, Wuling Tang (Five-Ingredient Decoction with Poria) is indicated.
After sweating, if the pulse is floating and rapid, accompanied by irritability and thirst, Wuling San is indicated.
Originally, due to improper purgative treatment, epigastric fullness and stuffiness (Pi) occurred. After administering Xiexin Tang (Heart-Purging Decoction), the Pi did not resolve. If the patient is thirsty, has a dry and irritable mouth, and urination is difficult, Wuling Tang is indicated.
In Taiyang disease, the Cun (inch) position of the pulse is slow, the Guan (bar) position is floating, and the Chi (cubit) position is weak. The patient has fever and sweating, yet still fears cold, does not vomit, but only has epigastric stuffiness. This is caused by the physician's improper use of purgatives. If purgatives were not used, and the patient does not fear cold but is thirsty, the pathogen has transferred to the Yangming channel.
If urination is frequent, the stool must be hard. Even if no bowel movement occurs for ten days, the patient suffers no distress. If thirsty and desiring water, provide it in small amounts; treat according to proper principles. For those who are thirsty, Wuling San is suitable.
In Shanghan (Cold Damage) disease, if sweating is followed by thirst, Wuling San is indicated. If there is no thirst, Fuling Gancao Tang (Poria and Licorice Decoction) is indicated.
In Shanghan disease, if there is cold extremities (Jue) and palpitations in the epigastrium, water retention should be treated first with Fuling Gancao Tang.
In Taiyang disease, if mild wheezing occurs after purgative treatment, it is because the exterior syndrome has not resolved. Guizhi Jia Houpo Xingren Tang (Cinnamon Twig Decoction plus Magnolia Bark and Apricot Kernel) is indicated.
For patients with a chronic history of wheezing, using Guizhi Tang (Cinnamon Twig Decoction) plus Houpo (Magnolia Bark) and Xingren (Apricot Kernel) is beneficial.
Originally suffering from Taiyang disease, if the physician erroneously uses purgatives, resulting in abdominal fullness, severe solidness, and pain, Guizhi Jia Dahuang Tang (Cinnamon Twig Decoction plus Rhubarb) is indicated.
In Shanghan, if the exterior syndrome is unresolved and there is fluid retention in the epigastrium, presenting with dry retching, fever, and cough, or alternatively thirst, diarrhea, belching, difficulty in urination with lower abdominal fullness, or wheezing, Xiao Qinglong Tang (Minor Blue Dragon Decoction) is indicated.
In Shanghan, if there is fluid retention in the epigastrium, presenting with cough and mild wheezing, fever, but no thirst, Xiao Qinglong Tang is indicated.
If thirst occurs after taking the decoction, it indicates that the cold pathogen has departed and the disease is about to resolve.
In Shanghan, if stagnant heat is trapped inside, the body will likely develop jaundice. Mahuang Lianqiao Chixiaodou Tang (Ephedra, Forsythia, and Red Bean Decoction) is indicated.
In combined Taiyang and Yangming disease, if there is no diarrhea but vomiting occurs, Gegen Jia Banxia Tang (Kudzu Root plus Pinellia Decoction) is indicated.
In Shanghan, if fever persists despite sweating, with epigastric hardness, vomiting, and diarrhea, Da Chaihu Tang (Greater Bupleurum Decoction) is indicated.
In Taiyang disease, if the course extends beyond ten days and the physician erroneously uses purgatives two or three times, and after four or five days the Chaihu syndrome remains, administer Xiao Chaihu Tang (Lesser Bupleurum Decoction) first. If vomiting continues, there is urgency and tightness in the epigastrium, and slight depression/irritability, the disease is unresolved. Using Da Chaihu Tang to purge will lead to recovery.
In Shanghan lasting over ten days, if heat is consolidated internally while alternating chills and fever persist, Da Chaihu Tang is administered.
After Shanghan, if the pulse is deep and solid, indicating internal excess, purgation is required, and Da Chaihu Tang is suitable.
In Shanghan unresolved for thirteen days, with chest and hypochondriac fullness and vomiting, tidal fever occurring at dusk, followed by mild diarrhea: this was originally a Chaihu syndrome. Purging should not have caused diarrhea. The fact that diarrhea now occurs indicates the physician used pill-based purgatives, which was incorrect. Tidal fever indicates excess. First, use Da Chaihu Tang to resolve the exterior, then use Chaihu Jia Mangxiao Tang (Bupleurum plus Mirabilite Decoction).
According to the above syndromes, all belong to unresolved exterior syndromes, while the interior may have accumulated water, retained phlegm, stored food, or accumulated heat. The exterior is excess, and the interior is also excess; thus, they are collectively categorized as "Exterior and Interior Excess Syndromes."
**Wuling San (Five-Ingredient Powder with Poria)**
Zhenling (Polyporus), 18 Zhu; Zexie (Alisma), 1 Liang 6 Qian; Baizhu (Atractylodes Macrocephala), 18 Zhu; Guizhi (Cinnamon Twig), half Liang; Fuling (Poria), 18 Zhu.
(Note: 1 Liang equals 24 Zhu; 18 Zhu equals 7.5 Qian.)
Grind into powder. Mix with rice water and take 3 Qian per dose, three times daily. Drink plenty of warm water afterwards until sweating occurs for recovery.
Commentary: Since the exterior pathogen is unresolved and water qi is stagnant internally, Guizhi is used to circulate the channels and release the exterior; Baizhu dries dampness and generates fluids; Zhenling, Fuling, and Zexie promote urination and drain dampness.
**Fuling Gancao Tang (Poria and Licorice Decoction)**
Fuling (Poria), 2 Qian; Guizhi (Cinnamon Twig), 2 Qian; Gancao (Licorice), 2 Qian; Shengjiang (Fresh Ginger), 3 Qian.
Decoct in water and take.
Commentary: Absence of thirst indicates lighter dampness. Thus, Fuling, Guizhi, Shengjiang, and Gancao are used to drain water and soothe the Liver (Wood), harmonize the Middle and strengthen the Spleen (Earth), preventing dampness from moving and causing water stagnation.
**Guizhi Jia Houpo Xingren Tang (Cinnamon Twig Decoction plus Magnolia Bark and Apricot Kernel)**
Guizhi (Cinnamon Twig), 3 Qian; Gancao (Licorice), 2 Qian; Shaoyao (Peony), 3 Qian; Dazao (Jujube), 4 pieces; Xingren (Apricot Kernel), 14 pieces; Houpo (Magnolia Bark), 1.5 Qian; Shengjiang (Fresh Ginger), 3 Qian.
Decoct in water. Aim for a slight sweat.
Commentary: Since the exterior pathogen is unresolved and interior Qi is obstructed, Guizhi releases the exterior, while adding Houpo and Xingren descends rebellious Qi and breaks congestion.
**Guizhi Jia Dahuang Tang (Cinnamon Twig Decoction plus Rhubarb)**
Guizhi (Cinnamon Twig), 3 Qian; Shaoyao (Peony), 6 Qian; Gancao (Licorice), 2 Qian; Shengjiang (Fresh Ginger), 3 Qian; Dazao (Jujube), 4 pieces; Dahuang (Rhubarb), 0.7 Qian.
Decoct in water and take.
Commentary: The exterior syndrome is unresolved, and erroneous purgation led to abdominal fullness, severe solidness, and pain. Guizhi releases the exterior; doubling Shaoyao clears/dries the Liver Wood; adding Dahuang drains Spleen Earth stagnation.
**Xiao Qinglong Tang (Minor Blue Dragon Decoction)**
Mahuang (Ephedra), 2 Qian; Shaoyao (Peony), 2 Qian; Xixin (Asarum), 1 Qian; Ganjiang (Dried Ginger), 2 Qian; Guizhi (Cinnamon Twig), 2 Qian; Gancao (Licorice), 2 Qian; Wuweizi (Schisandra), 1 Qian; Banxia (Pinellia), 1.5 Qian.
Boil Mahuang first, remove foam, then add other herbs and decoct.
Modifications: If mild diarrhea, remove Mahuang, add Raohua (now replaced by Fuling for stability); if thirsty, remove Banxia, add Gualougen (Trichosanthes Root) 2 Qian; if choking sensation, remove Mahuang, add Paofuzi (Prepared Aconite) 1 Qian; if difficulty urinating with lower abdominal fullness, add Fuling 3 Qian; if wheezing, remove Mahuang, add Xingren (Apricot Kernel) 13 pieces.
Commentary: Exterior syndrome unresolved, water qi stagnant and obstructive. Gancao nourishes Middle Qi; Mahuang and Guizhi disperse Ying and Wei; Shaoyao clears Wind-Wood; Banxia descends rebellious Qi and stops vomiting; Wuweizi, Xixin, and Ganjiang descend rebellious Qi and stop coughing.

Use rainwater (Liaoshui). Boil Mahuang in 2.5 cups until reduced to 2 cups, remove dregs, add other herbs, decoct to 0.8 cup, take warm.
Commentary: In Shanghan exterior disease, dampness stagnates generating interior heat. Without sweat or urine to vent, jaundice develops. Mahuang vents skin/lung congestion; Xingren descends Lung Qi; Shengzibapi clears Ministerial Fire and soothes Liver Wood; Lianqiao and Chixiaodou drain damp-heat and promote urination; Jiang, Gan, and Dazao harmonize Stomach Qi and tonify Spleen Essence. Sweating and promoting urination eliminate jaundice.
**Gegen Jia Banxia Tang (Kudzu Root plus Pinellia Decoction)**
Gegen (Kudzu Root), 4 Qian; Mahuang (Ephedra), 3 Qian; Shaoyao (Peony), 2 Qian; Shengjiang (Fresh Ginger), 2 Qian; Gancao (Licorice), 2 Qian; Guizhi (Cinnamon Twig), 2 Qian; Dazao (Jujube), 4 pieces; Banxia (Pinellia), 2 Qian.
Boil Mahuang and Gegen first, remove foam, add other herbs, decoct and take.
Commentary: Combined Taiyang and Yangming disease causes channel pressure and Fu organ stagnation, unable to accommodate undigested food, leading to forced vomiting. Gegen and Mahuang vent Wei stagnation in both Yang channels; Banxia descends Stomach rebellious Qi and stops vomiting.
