治疗暑毒侵入心脏，出现发热、极度口渴、小便不通利；以及暑湿相互搏结，导致自汗、身体沉重（方剂见利湿门）。若患者口渴明显，去掉桂枝，加入黄连（朱丹溪说：滑伯仁常常怀疑治疗暑病不应当发汗，因为暑气伤心，热气耗伤元气，汗是心的液汁，出汗过多必然导致亡阳，
治疗太阳中暍证，表现为身体发热、出汗、脚冷、怕冷、脉象微弱且口渴（方剂见泻火门）。
湿气属于阴邪。经典记载：地面的湿气过盛，就会伤害皮肉筋脉。又说：各种湿邪导致的肿胀和腹满，都归属于脾。湿气，是土的气化表现。
治疗太阳病经过发汗治疗后，大汗出，导致胃中干燥，烦躁不能入睡，想要喝水的，少量多次给予饮水，使胃气调和就能痊愈；如果脉象浮，小便不利，轻微发热且消渴（口渴多饮），这个汤剂主治（脉浮表示表证仍在，便秘热渴表示腑证已急迫，用此方两解表里）；以及中风发热，六七天未解除且心烦，有表里证候，想喝水，水喝进去就吐出来，名叫水逆（表是指外证未罢，里是指烦渴属于腑证，邪热挟带积饮上逆，所以外面的水被格拒而不能进入）；以及伤寒痞满，服用泻心汤后未缓解，口渴且烦躁，小便不利（本方功效擅长荡涤热邪、滋润燥热，引导饮邪、生津液，所以也是消除痞满的良好方剂。程郊倩说：邪气在上焦而治疗在下焦，是让浊阴从下窍排出，那么在上焦的清阳自然能够宣通化散。心邪不从心经泻除而从小肠泻除，这是另一种方法。汪昂按语：这乃是正治法，不是另一种方法，这是腑实而泻其腑的方法）。通用治疗各种湿气导致的腹满，饮水或水肿，呕吐逆气，泄泻，水寒射肺，或者气喘或者咳嗽，中暑烦渴，身体发热头痛，膀胱积热，便秘且口渴，霍乱吐泻，痰饮湿疟，身体疼痛身体沉重（这些都是伤湿的表现。湿胜则脾不运化，土不能制约水，溢于皮肤则肿胀，并入大肠则泄泻，水停于心下则呕吐逆气，水寒射肺则喘咳。暑气先入心故烦渴，五苓散利小水、降心火，所以兼治中暑烦渴。肺病则金不能生水，膀胱热则阳不能化阴，所以便秘而渴；阴阳不和，则霍乱吐泻；湿胜则身痛身重。大抵下部不通利，则阴阳不能升降，而变证就多了）。
猪苓、茯苓、白术（炒，十八铢）、泽泻（一两六铢半）、桂枝（半两。按语：杂病当用桂枝，伤寒证中表未解者仍当用桂枝，兼取解表作用）。研为末。每次服用三钱。服药后多喝热水，出汗即愈。伤暑者，加入朱砂。
这是足太阳膀胱经的药。太阳的热邪，传入膀胱之腑，所以口渴而大便不通。经典记载：淡味具有渗泄作用，属于阳；二苓（猪苓、茯苓）味甘淡，入肺经而通利膀胱，作为君药（水与五味无直接对应关系，所以淡能利水。茯苓走气分，猪苓走血分，但必须上行于肺，然后才能下降入膀胱）；咸味具有涌泄作用，属于阴；泽泻味甘咸，入肾、膀胱经，共同利水道，作为臣药；培补脾胃所以能制约水湿，所以用白术苦温健脾去湿，作为佐药；膀胱是津液藏聚的地方，气化后才能排出，所以用肉桂辛热作为使药，热因热用，引入膀胱以化其气，使湿热之邪，都从小便排出（如果在汗下之后，体内津液亡失而导致小便不利者，不可用五苓散，恐怕再次亡失津液而更加亏损阴液，不要治疗它，大小便通畅自然会痊愈。也有大热如狂，小便不利而使用此汤剂的，是想让随经传入的太阳邪气直达膀胱，通过尿液排出，这也是“釜底抽薪”的意思。陈来章说：治疗便秘的方法有三：一是肺燥不能化气，所以用二苓、泽泻的甘淡，以泄肺而降气；二是脾湿不能升精，所以用白术的苦温，以燥脾而升精；三是膀胱无阳不能化气，所以用肉桂的辛热，以温膀胱而化阴；使水道通利，那么上面可以止渴，中间可以去湿，下面可以泄邪热。李东垣说：五苓散，是太阳里证的下法药。太阳病在表则发汗解之，在里则引邪竭之。口渴，是邪气入太阳本经，当下之，使邪从膀胱排出。小便利者不宜用，然而太阳病热而渴，小便虽然利，也宜用五苓散下之。又说：邪气在荣卫之间，叫做半表半里，五苓散分理膀胱经的半表半里，理中汤治疗吐泻上下之间的半表半里。《活人书》说：脉浮大是表证，应当发汗；其人发热烦渴，小便赤，却应当下法；这是表里俱见，五苓散主治。五苓散利水，为什么能止渴生津？因为湿热壅塞于中焦，则气不得施化，所以津液枯竭而小便不通；用五苓散利其小便，则湿热下消，津液回复而口渴停止，这也符合《内经》通因通用的意思。李东垣说：伤饮，是无形的邪气，宜发汗、利小便，以导其湿；伤食，是有形的……
本方去掉桂枝，名叫四苓散（李东垣说：没有恶寒证，不可用桂枝。周扬俊说：五苓散是为口渴而小便不利者设立的，如果不渴则茯苓甘草汤足够了，如果只是口渴则四苓散足够了）；本方加入辰砂，名叫辰砂五苓散：并治小便不利。本方加入苍术，名叫苍桂五苓散：治疗寒湿。本方加入茵陈，名叫茵陈五苓散：治疗湿热发黄，便秘烦渴。本方加入羌活，名叫元戎五苓散：治疗中焦积热。本方加入石膏、滑石、寒水石，以清六腑之热，名叫桂苓甘露饮（《宣明论》另见于火门）。本方去掉桂枝、泽泻，名叫猪苓散（《金匮要略》）：治疗呕吐，病位在膈上，想喝水的人。本方单用肉桂、茯苓，等分，蜜丸，名叫桂苓丸：治疗冒暑烦渴，引饮过多，腹胀便赤。本方单用泽泻（五两）、白术（二两），名叫泽泻汤（《金匮要略》）：治疗心下支饮，常苦于眩晕。本方单用茯苓、白术，等分，名叫茯苓白术汤：治疗脾虚不能制水，湿盛泄泻。再加郁李仁，入姜汁服，名叫白茯苓汤：治疗水肿。本方加川楝子，治疗水疝。本方加人参，名叫春泽汤；再加甘草（合四君子汤），也叫春泽汤：治疗无病而渴与病愈后渴者。本方去掉桂枝，加入苍术、甘草、芍药、栀子、黄芩、羌活，名叫二术四苓汤：能治疗表里湿邪，兼清暑热。本方倍用桂枝，加入黄柏如白术的数量，治疗伤暑大汗不止。本方加甘草、滑石、栀子，入食盐、灯草煎，名叫节庵导赤散：治疗热蓄膀胱，便秘而渴；如中湿发黄，加茵陈；水结胸，加木通。本方合益元散，治疗诸湿淋沥。再加琥珀，名叫茯苓琥珀汤（谦甫说：治疗小便数而欠，即小便频而短也）。本方合平胃散，名叫胃苓汤，一名对金饮子：治疗中暑伤湿，停饮夹食，腹痛泄泻，及口渴便秘（这是上下分消其湿。按语：《机要》论泄泻，有属风、属湿、属寒、属火，这是因于外感的；《三因极一病证方论》言七情感动，脏气不平，也致溏泻，这是因于内伤的；外则当调六气，内则当调五脏。又有因饮食所伤而泄者，法当消导；因风飧泄者，当解散；因痰积上焦，致大肠不固而泄者，当除痰；有脾胃气虚而泄者，当补中益气，使胃气升腾，而泄自止）。本方合黄连香薷饮，名叫薷苓汤：治疗伤暑泄泻。本方合小柴胡汤，名叫柴苓汤：治疗泄泻发热口渴，疟疾热多寒少，口燥心烦。以上三方，并加姜、枣煎煮。深师用本方治疗头发变白及脱发：白术（一斤）、桂枝（半斤）、二苓、泽泻（各四两），更名茯苓术散。
Treats summer-heat toxin invading the Heart, presenting with fever, extreme thirst, and difficult urination; as well as summer-heat and dampness clashing, causing spontaneous sweating and heaviness of the body (Formula see in Dampness-Draining Section). If thirst is prominent, remove Cinnamon Twig (Guizhi), add Coptis Rhizome (Huanglian) (Zhu Danxi said: Hua Borén often doubted that diaphoresis should not be used for summer-heat diseases, because summer-heat injures the Heart, heat damages Qi, sweat is the fluid of the Heart, excessive sweating will inevitably lead to collapse of Yang,
Treats Taiyang Zhongshu (Heatstroke affecting the Taiyang channel), manifesting as body heat, sweating, cold feet, aversion to cold, faint pulse, and thirst (Formula see in Fire-Draining Section).
Treats thirst caused by summer-heat injury, with a deficient pulse (Formula see in Fire-Draining Section).
Dampness is a Yin pathogen. The Classics state: When the dampness of the earth is excessive, it harms the skin, flesh, sinews, and vessels. It also states: All dampness-induced swelling and fullness belong to the Spleen. Dampness is the Qi transformation of Earth.
Treats cases where Taiyang disease, after sweating therapy, results in profuse sweating, dryness in the Stomach, irritability and inability to sleep, and desire for water. Give small amounts frequently; when the Stomach Qi harmonizes, the patient recovers. If the pulse is floating, urination is difficult, there is slight fever, and polydipsia (extreme thirst), this decoction is indicated (A floating pulse indicates the exterior syndrome persists; constipation, heat, and thirst indicate the interior Fu organ syndrome is urgent; this formula resolves both exterior and interior). Also treats Wind-stroke with fever persisting for six or seven days without resolution, accompanied by vexation, presenting with both exterior and interior signs, desire to drink water, but vomiting immediately after drinking, named Water Reversal (Exterior refers to unresolving external symptoms; Interior refers to vexation and thirst belonging to the Fu organs; pathogenic heat carrying accumulated fluid rebels upward, so ingested water is rejected and cannot enter). Also treats Cold Damage epigastric fullness, where Xixin Decoction failed to resolve symptoms, accompanied by thirst, irritability, and difficult urination (This formula excels at purging heat, moistening dryness, guiding out fluid retention, and generating fluids, thus it is also an excellent formula for resolving fullness. Cheng Jiaoqian said: Treating pathogens in the Upper Jiao by acting on the Lower Jiao allows turbid Yin to exit through the lower orifices, allowing clear Yang in the Upper Jiao to naturally circulate and transform. Pathogenic factors in the Heart are drained via the Small Intestine, which is another method. Wang Ang notes: This is standard treatment, not an alternative method; it is treating Fu excess by draining the Fu organ). It generally treats various dampness-induced abdominal fullness, edema from water retention, vomiting and regurgitation, diarrhea, Cold-Damp attacking the Lungs causing wheezing or coughing, summer-heat with vexation and thirst, fever and headache, Heat accumulation in the Bladder, constipation with thirst, cholera with vomiting and diarrhea, phlegm-fluid retention and damp malaria, body pain and heaviness (These are all manifestations of Dampness injury. Excessive Dampness impairs Spleen transportation, Earth fails to control Water; overflowing into the skin causes swelling, entering the Large Intestine causes diarrhea, stopping below the Heart causes vomiting, Cold-Water attacking the Lungs causes wheezing and coughing. Summer-heat enters the Heart first, causing vexation and thirst; Wuling San promotes urination and descends Heart Fire, thus it also treats summer-heat with vexation and thirst. Lung disease means Metal cannot generate Water; Bladder Heat means Yang cannot transform Yin, leading to constipation and thirst; Yin-Yang disharmony leads to cholera with vomiting and diarrhea; Excessive Dampness leads to body pain and heaviness. Generally, if the lower orifices are not unobstructed, Yin and Yang cannot ascend and descend, leading to many complications).
Polyporus (Zuling), Poria (Fuling), Atractylodes Macrocephala Rhizome (Baizhu) (stir-fried, 18 zhu), Alisma Rhizome (Zexie) (1 liang 6 zhu half), Cinnamon Twig (Guizhi) (0.5 liang. Note: For miscellaneous diseases, Guizhi should be used; for Cold Damage where the exterior is unresolved, Guizhi should still be used to simultaneously release the exterior). Grind into powder. Take 3 qian per dose. Drink plenty of hot water after administration; recovery occurs with sweating. For summer-heat injury, add Cinnabar (Zhusha).
This is a medicine for the Foot-Taiyang bladder channel. Heat from Taiyang transmits to the Bladder Fu organ, causing thirst and urinary obstruction. The Classics state: Bland flavors have seeping and draining properties and belong to Yang; the two Ling herbs (Polyporus and Poria) are sweet and bland, enter the Lung meridian, and unblock the Bladder, serving as Sovereign herbs (Water has no specific correspondence to the five flavors, so blandness can promote urination. Fuling moves in the Qi level, Zuling moves in the Blood level, but they must ascend to the Lung before descending into the Bladder); Salty flavors have surging and draining properties and belong to Yin; Alisma Rhizome (Zexie) is sweet and salty, enters the Kidney and Bladder meridians, jointly promoting water pathways, serving as Minister herbs; Strengthening Earth controls Water, so Bitter-Warm Atractylodes Macrocephala Rhizome (Baizhu) strengthens the Spleen and removes Dampness, serving as Assistant herbs; The Bladder stores fluids, and Qi transformation allows them to exit, so Acrid-Hot Cinnamon Bark (Rougui) serves as Guide herbs. Using heat to treat heat, it guides the action into the Bladder to transform Qi, allowing Damp-Heat pathogens to exit via small urination (If after sweating or purging, internal loss of body fluids leads to urinary difficulty, Wuling San should not be used, lest it further deplete fluids and Yin; do not treat it directly, normal urination will restore itself spontaneously. There are also cases of severe heat with delirium and urinary difficulty where this decoction is used, aiming to direct Taiyang pathogens traveling along the channels directly to the Bladder to exit via urine, which embodies the principle of "pulling firewood from under the pot". Chen Laizhang said: There are three ways to treat constipation: First, Lung dryness fails to transform Qi, so use the sweet-bland Polyporus and Alisma to drain the Lung and descend Qi; Second, Spleen dampness fails to raise essence, so use bitter-warm Atractylodes to dry the Spleen and raise essence; Third, Bladder lacks Yang to transform Qi, so use acrid-hot Cinnamon to warm the Bladder and transform Yin; once water pathways are unobstructed, it stops thirst above, removes dampness in the middle, and drains pathogenic heat below. Li Dongyuan said: Wuling San is a purgative for Taiyang interior syndromes. Taiyang superficial syndromes are treated by sweating; interior syndromes are treated by guiding them out. Thirst indicates pathogens have entered the Taiyang root, requiring purging to allow exit via the Bladder. It is unsuitable if urination is already free, yet even if urination is free, if Taiyang heat causes thirst, Wuling San should still be used to purge. He also stated: Pathogens between Ying and Wei are called Half-Exterior Half-Interior; Wuling San regulates the Half-Exterior Half-Interior of the Bladder channel, while Lizhong Tang treats the Half-Exterior Half-Interior of vomiting and diarrhea. *Huoren* states: Floating and large pulses indicate exterior syndromes, requiring sweating; fever, vexation, thirst, and red urine indicate interior syndromes requiring purging; when both exterior and interior signs are present, Wuling San is indicated. How can Wuling San, which promotes urination, stop thirst and generate fluids? Because Damp-Heat stagnates in the Middle Jiao, Qi cannot transform, leading to fluid exhaustion and urinary obstruction; using Wuling San to promote urination eliminates Damp-Heat downward, restoring fluids and stopping thirst, aligning with the *Neijing* principle of "treating obstruction with unblocking methods". Li Dongyuan said: Injury from fluids involves formless pathogens, suitable for sweating and promoting urination to guide out Dampness; injury from food involves tangible...
Removing Cinnamon Twig from this formula yields Siling San (Li Dongyuan said: Without aversion to cold, Cinnamon Twig should not be used. Zhou Yangjun said: Wuling San is designed for thirst with difficult urination; if no thirst, Fuling Gancao Decoction suffices; if only thirst, Siling San suffices); Adding Cinnabar yields Chensha Wuling San: Both treat difficult urination. Adding Atractylodes Lancea Rhizome (Cangzhu) yields Canggui Wuling San: Treats Cold-Damp. Adding Artemisiae Scopariae Herba (Yinchen) yields Yichen Wuling San: Treats Damp-Heat jaundice with constipation and thirst. Adding Notopterygium Rhizome (Qianghuo) yields Yuanrong Wuling San: Treats Middle Jiao heat accumulation. Adding Gypsum Fibrosum (Shigao), Talcum (Huashi), and Hypocoelites (Hanshui Shi) clears Heat of the Six Fu organs, yielding Guiling Ganlu Yin (*Xuanming Lun* sees in Fire Section). Removing Cinnamon Twig and Alisma Rhizome yields Zhuling San (*Jinkui Yaolue*): Treats vomiting, pathology above the Diaphragm, with desire for water. Using equal parts Cinnamon Twig and Poria, honey-pilled, yields Guiling Wan: Treats summer-heat vexation and thirst, excessive drinking, abdominal distension, and red urine. Using only Alisma Rhizome (5 liang) and Atractylodes Macrocephala Rhizome (2 liang) yields Zexie Tang (*Jinkui Yaolue*): Treats subdiaphragmatic fluid retention with frequent dizziness. Using equal parts Poria and Atractylodes Macrocephala Rhizome yields Fuling Baizhu Tang: Treats Spleen deficiency failing to control Water, excessive Dampness diarrhea. Adding Prunus Li Seed (Yuliren) taken with Ginger Juice yields Bai Fuling Tang: Treats edema. Adding Toosendan Fruit (Chuanlianzi) treats Hydrocele. Adding Ginseng Radix et Rhizoma (Renshen) yields Chunze Tang; adding Licorice Root (Gancao) combined with Sizijunzi Tang also yields Chunze Tang: Treats thirst without disease and thirst after convalescence. Removing Cinnamon Twig, adding Atractylodes Lancea Rhizome, Licorice Root, White Peony Root, Gardenia Fruit, Scutellaria Root, and Notopterygium Rhizome yields Ershu Siling Tang: Treats exterior-interior Dampness and clears summer-heat. Doubling Cinnamon Twig and adding Phellodendron Cortex (Huangbai) in equal amount to Atractylodes treats summer-heat with profuse sweating. Adding Licorice Root, Talcum, and Gardenia Fruit, decocted with Salt and Juncus Effusus (Dengcao) yields Jian'an Daochi San: Treats Heat accumulating in the Bladder with constipation and thirst; for Damp-Heat jaundice, add Artemisiae Scopariae Herba; for Fluid binding in the Chest, add Akebia Caulis (Mutong). Combining with Yi Yuan San treats various dampness-related dribbling urination. Adding Amber yields Fuling Hupo Tang (Qianfu says: Treats frequent short urination). Combining with Pingwei San yields Weiling Tang, also known as Duijin Yinzi: Treats summer-heat with Dampness injury, retained fluids with food stagnation, abdominal pain and diarrhea, and thirst with constipation (This disperses Dampness from upper and lower). Note: *Jiyao* discusses diarrhea due to Wind, Dampness, Cold, and Fire, originating from external pathogens; *Sanyin* mentions emotional disturbances causing organ imbalance leading to loose stools, originating from internal injuries; externally regulate the Six Qi, internally regulate the Five Zang. Diarrhea due to dietary injury requires digestion-promoting methods; Wind-induced diarrhea requires dispersion; Phlegm accumulation in the Upper Jiao causing Large Intestine insecurity requires phlegm-resolving methods; Spleen-Stomach Qi deficiency diarrhea requires tonifying Middle Qi to raise Stomach Qi, stopping diarrhea spontaneously. Combining with Huanglian Xiangru Yin yields Ruling Tang: Treats summer-heat diarrhea. Combining with Xiaochaihu Tang yields Chailing Tang: Treats diarrhea with fever and thirst, malaria with more heat than chills, dry mouth, and vexation. The above three formulas are decocted with Ginger and Jujube. Shenshi used this formula to treat white hair and alopecia: Atractylodes Macrocephala Rhizome (1 jin), Cinnamon Twig (0.5 jin), the two Ling herbs, and Alisma Rhizome (4 liang each), renamed Fuling Zhu San.
