【集注】柯琴说:阳明病邪气从热化,所以不恶寒而恶热;热气蒸腾外越,所以汗出且自汗;热气灼烧胃中,所以口渴想喝水;邪气盛实,所以脉滑,但病邪仍在经络,所以兼见浮脉。大概阳明经属胃,外主肌肉,虽然有大热但未形成里实证,终究不是苦寒药物所能治疗的。石膏味辛性寒,辛能解除肌表之热,寒能清胜胃中之火,寒性沉降,辛能走散于外,兼具内外两方面的功效,所以作为君药。知母味苦质润,苦能泻火,润能滋润燥热,所以作为臣药。使用甘草、粳米在中焦调和,并且能在土中泻火,顺应稼穑作甘的特性,寒剂得到它们可以缓和其寒性,苦药得到它们可以平抑其苦味,使沉降的药性能够停留于体内发挥作用。有了这两味药作为佐使,大寒的药物就不会有损伤脾胃的顾虑了。煮成汤剂入胃后,输布至脾并归肺,水精四布全身,大烦渴的症状即可消除。白虎是西方金神,取此名来命名方剂,如同秋金当令而炎暑自然消散一样。再加人参来补中益气并生津液,协和甘草、粳米的补益作用,制约石膏、知母的寒性,泻火而不伤脾胃,这是万全的治疗策略。
白虎加人参汤,治疗太阳中热(中暑),症见汗出、恶寒、身热且口渴者,就是此方。
石膏(一斤) 知母(六两) 甘草(二两) 粳米(六合) 人参(三两)
以上五味药,用水按照前面的煎煮服用方法处理。
【集注】赵良说:汗出、恶寒、身热但不口渴的,是中风证。汗出、恶寒、身热且口渴的,是中暍(中暑)。它们的症状相似,唯独以是否口渴来辨别。然而伤寒、中风,都有背部轻微恶寒和时时恶风且口渴的情况,也用白虎加人参汤治疗。大概是因为火热灼伤肺金,肺主一身之气。肺受伤则卫气虚弱,卫气虚则体表不足,因此出现汗出、身热、恶寒。《内经》说:“移热于肺,传为膈消。”膈消就会口渴,这都是相火伤肺所致,可知关键在于救肺。石膏能治三焦火热,功效多于清肺,退去肺中之火,所以用为君药。知母也在肺中泻心火,滋补水之源,人参生津并补益所伤之气,作为臣药。粳米、甘草补益脾胃(土)以资助肺(金),作为佐药。
猪苓汤,治疗阳明病,脉浮发热,口渴想喝水;或少阴病下利六七日后,咳嗽、呕吐、口渴、心烦不得眠者。
以上五味药,用水四升,先煮前四味药,取二升药汁,去渣;加入阿胶,烊化溶解,温服七合,每日三次。
【集注】赵羽皇说:张仲景制定猪苓汤这一方剂,用来通行阳明、少阴二经的水热之邪。然而其主旨全在于益阴,不仅仅专利尿。大概伤寒表虚最忌讳亡阳,而里热又担心亡阴。亡阴,是指肾中之阴与胃家津液的耗亡。所以阴虚之人,不但大便不可轻易攻下,即使小便也不宜过度通利。因为阴虚之人如果过于渗利,津液反而会导致耗竭。方中阿胶质地如膏,养阴滋润燥热;滑石性滑,清热利水;配合二苓(猪苓、茯苓)的渗泄作用,既能疏通浊热而不留瘀滞,又能滋润真阴而不致枯燥,这是利水而不伤阴的良好方剂。所以太阳病利水用五苓散的,是因为太阳职司寒水,所以加桂枝以温之,这是暖肾以行水。阳明、少阴病用猪苓汤,是因为这两经都关乎津液,特意用阿胶、滑石来滋润,这是滋养无形之气以推动有形之水。虽然都是利水,但寒温截然不同,只有明理的人才能知晓。
五苓散(附:茵陈五苓散),治疗脉浮、小便不利、微热消渴者。发汗后,脉浮数、烦渴者。中风发热,六七日未解,且烦躁,有表里证,口渴想喝水,水入则吐者。
茯苓(十八铢) 猪苓(十八铢) 白术(十八铢) 泽泻(一两) 桂枝(半两)
以上五味药研为散剂,用白饮(米汤)调服一方寸匕,每日三次,多服暖水,出汗即愈。
【注】这个方剂,是治疗太阳邪热入腑,水气不化,针对膀胱表里的药物。一种治疗水逆,水入则吐;一种治疗消渴,水入则消。膀胱是津液之府,气化功能正常才能排出尿液。邪热侵入,如果水盛则水壅滞不化而蓄水于上,膀胱的气化不行,导致小便不利。如果热盛则水被热消耗,水在上方被消烁,膀胱的津液枯竭,也导致小便不利。水入即吐的,是水盛于热;水入即消的,是热盛于水。这两种证候都是小便不利,所以都用此方主治。然而小便利者不可用,恐怕重伤津液。由此可知五苓散并非专门治水热的方剂,而是治疗水热导致小便不利的主方。以泽泻的咸寒为君,咸走水府,寒胜热邪。佐以二苓的淡渗,通调水道,下输膀胱,共同泻除水热。使用白术的燥湿,健脾助土,作为堤防以制水。使用桂枝的辛温,宣通阳气,蒸化三焦以行水。泽泻得二苓下降,利水之功倍增,小便利而水不蓄积。白术须得桂枝上升,通阳之效迅速,气腾津化,口渴自止。如果发热表证不解,用桂枝代替肉桂,服药后多服暖水,令汗出而愈。这说明此方不止治疗停水导致的小便不利之里证,还能解除停水导致的发热之表证。加人参名为春泽汤,其意专在助气化以生津。加茵陈名为茵陈五苓散,治疗湿热发黄,表里不实,小便不利者,无不治愈。
桂枝去芍药加茯苓白术汤,治疗服用桂枝汤或经过攻下后,无头项强痛,翕翕发热,无汗,心下满微痛,小便不利者,由桂枝去芍药加茯苓白术汤主治。
在桂枝汤方内,去掉芍药,加入茯苓、白术各三两,其余按照桂枝汤法煎服。小便利则痊愈。
【注】服用桂枝汤后已发汗,或者经过攻下后,现在没有头项强痛、翕翕发热、无汗等表证;有心下满微痛、小便不利等停饮之里证;若无汗表不解,心下有水气,应当用小青龙汤发汗。现在无汗表不解,有水气,心下满微痛,小便不利,却不用小青龙汤,是因为已经经过汗下,表里俱虚。所以仍用桂枝汤以解表,去掉芍药的酸收,避开无汗心下之满;加入茯苓的燥渗,因为水停导致小便不利。其余按照桂枝汤法煎服,意思是按照桂枝汤法取汗。小便利则愈,意思是饮水病通过输布水道则痊愈。此方即苓桂甘术汤而有生姜、大枣。其意专在解肌,利水次之,所以用生姜、大枣佐助桂枝,以通津液取汗。苓桂甘术汤不用生姜、大枣而加茯苓,其意专在利水,扶阳次之,所以倍加茯苓为君,桂枝为臣,于利水中扶阳。所以方后不说“根据服桂枝汤方”。
十枣汤,治疗太阳中风表证已解,汗出且不恶寒,里有水气,小便不利,呕逆短气,心下至胁部痞满硬痛者。这是治水气的急方。
以上三味药,分别捣碎为散剂,用水一升半,先煮肥大的十枚大枣,取八合药汁,去渣;加入药末,体质强壮的人服一钱,体弱的人服半钱,清晨温服。如果泻下少且病未除,第二天再服,增加半钱。得快下后,喝糜粥自行调养。
【集注】柯琴说:张仲景治疗水气的方剂,种种不同,这是其中最峻猛的。凡是水气为患,有的喘咳,有的心悸,有的噎塞,有的呕吐,有的下利,病在一处而止。这里则是水邪留结于中焦,心腹胁下痞满硬痛,三焦升降之气阻隔难通。此时表邪已罢,不适合用汗散之法,里饮实盛,也不是淡渗之品所能胜任,如果不选用逐水至峻猛的药物来折服它,则中气不支,束手待毙。甘遂、芫花、大戟三味药,皆辛苦气寒而禀性最毒,并举而用之,气味相济相须,所以可以夹攻水邪的巢穴,决渎水道而大下之,一举而患可平。然而邪气聚集之处,正气必虚;用毒药祛除邪气,必然伤及脾胃,所以必须使元冲和甘缓的药物为主宰,则邪气尽而生命亦得以保全。然而这些药最毒,参、术不能为君,甘草又与之相反,所以选十枚大而肥的大枣为君药,一来顾护脾胃,二来缓和其峻毒。得快利后,喝糜粥自行调养,一来使谷气内充,二来使邪气不再发作。这是张仲景用毒攻病的方法,尽美又尽善。愚昧的人困惑于“甘能中满”的说法,而不敢使用,哪里知道承制之理呢?
[Annotations] Ke Qin stated: In Yangming disease, pathogenic factors transform into heat; therefore, there is aversion to cold but aversion to heat. Heat steams and escapes outward, causing spontaneous sweating. Heat scorches the stomach, causing thirst and a desire to drink water. The pathogen is abundant and excess, resulting in a slippery pulse, yet since it remains in the channels, a floating pulse is also present. Generally, the Yangming channel belongs to the Stomach and governs the muscles externally. Although there is intense heat, if it has not formed an interior excess syndrome, bitter-cold herbs alone cannot treat it. Gypsum (Shigao) is pungent and cold. Pungency can resolve muscle-heat, while coldness can overcome stomach-fire. Cold nature is sinking and descending, while pungency moves outward; thus, it excels in both interior and exterior functions, serving as the Sovereign herb. Anemarrhena (Zhimu) is bitter and moistening. Bitterness purges fire, while moisture nourishes dryness, serving as the Minister herb. Licorice (Gancao) and Rice (Jingmi) are used to harmonize the Middle Jiao. They can drain fire from Earth, adhering to the nature of grains that produce sweetness. The cold agents become milder with them, and bitter drugs become less harsh, allowing their sinking properties to linger within the body. With these two as Assistant and Envoy herbs, there is no fear that potent cold substances will damage the Spleen and Stomach. When decocted into soup and entering the Stomach, fluids are transported to the Spleen and returned to the Lung. Fluid essence distributes throughout the four directions, relieving severe irritability and thirst. Baihu (White Tiger) is the Golden Spirit of the West. Naming the formula after it implies that when Autumn Metal takes command, summer heat naturally dissipates. Adding Ginseng (Renshen) tonifies the Middle and benefits Qi while generating fluids, coordinating with the tonifying effects of Licorice and Rice, restraining the coldness of Gypsum and Anemarrhena, draining fire without injuring Earth. This is a comprehensive strategy.
Baihu Jia Renshen Tang (White Tiger Plus Ginseng Decoction) treats Sun Taiyang Zhongre (Heatstroke), characterized by sweating, aversion to cold, fever, and thirst.
Gypsum (1 jin), Anemarrhena (6 liang), Licorice (2 liang), Rice (6 he), Ginseng (3 liang).
The above five ingredients are prepared according to the previous decoction and administration method.
[Annotations] Zhao Liang stated: Sweating, aversion to cold, and fever without thirst indicate Wind Strike (Zhongfeng). Sweating, aversion to cold, fever, and thirst indicate Heatstroke (Zhongyue). The symptoms are similar, distinguished solely by the presence or absence of thirst. However, both Cold Damage (Shanghan) and Wind Strike can present with slight aversion to cold at the back, intermittent aversion to wind, and thirst, which are also treated with Baihu Jia Renshen Tang. This is because fire scorches Lung Metal, and the Lung governs Qi. Lung injury leads to deficient Wei Qi; deficient Wei Qi results in exterior insufficiency, leading to sweating, fever, and aversion to cold. The *Neijing* states: "Heat transferred to the Lung transmits to become Ge Xiao (Diaphragmatic Consumption)." Ge Xiao involves thirst, all caused by Minister Fire injuring the Lung. Thus, the key lies in saving the Lung. Gypsum treats Sanjiao fire, with efficacy extending beyond clearing the Lung, specifically retreating fire from the Lung, so it serves as the Sovereign herb. Anemarrhena also clears Heart fire from the Lung, nourishing the source of Water. Ginseng generates fluids and benefits injured Qi, serving as the Minister herb. Rice and Licorice tonify Earth to support Metal, serving as Assistant herbs.
Zhuling Tang (Polyporus Decoction) treats Yangming disease with a floating pulse, fever, and thirst for water; or Shaoyin disease with diarrhea for six to seven days, accompanied by cough, vomiting, thirst, irritability, and insomnia.
Polyporus (skin removed), Poria, Donkey-hide Gelatin, Talcum, Alisma (each 1 liang).
The above five ingredients are boiled in four sheng of water. First boil the first four ingredients until two sheng remain, strain; then add Donkey-hide Gelatin and melt it. Take seven ge warm, three times daily.
[Annotations] Zhao Yuhuang stated: Zhang Zhongjing formulated Zhuling Tang to circulate water and heat in the Yangming and Shaoyin channels. However, its main intent is entirely to nourish Yin, not merely to promote urination. Generally, exterior deficiency in Cold Damage most fears loss of Yang, while interior heat fears loss of Yin. Loss of Yin refers to the depletion of Kidney Yin and Stomach fluids. Therefore, in Yin-deficient individuals, not only should the bowels not be lightly purged, but urination should also be avoided through excessive diuresis. If Yin-deficient patients undergo excessive leaching and draining, fluids will be exhausted. In this formula, Donkey-hide Gelatin is pasty in texture, nourishing Yin and moistening dryness; Talcum is slippery, clearing heat and promoting urination. Assisted by the draining actions of the two Polypori (Polyporus and Poria), it disperses turbid heat without retaining stasis and moistens True Yin without causing dryness. It is an excellent formula that promotes urination without damaging Yin. Therefore, Wuling San (Five-Ingredient Powder with Poria) is used for Yangming water-promotion because Yangming governs cold water, so Cinnamon Twig (Guizhi) is added to warm it, warming the Kidney to move water. For Yangming and Shaoyin, Zhuling Tang is used because both channels relate to fluids; specifically, Donkey-hide Gelatin and Talcum are used to moisten them. This nourishes the formless to move the formed. Although both promote urination, their cold and warm natures are vastly different, known only to the enlightened.
Wuling San (Five-Ingredient Powder with Poria) [Attached: Yinchen Wuling San] treats floating pulse, difficulty in urination, mild heat, and thirst. After sweating, if the pulse is floating and rapid with irritability and thirst. Wind Strike with fever, unresolved after six or seven days, with irritability, exterior and interior signs, thirst for water, and vomiting after drinking.
Poria (18 zhu), Polyporus (18 zhu), Atractylodes Macrocephala (18 zhu), Alisma (1 liang), Cinnamon Twig (0.5 liang).
The above five ingredients are powdered. Take one cun bi with white rice water, three times daily. Drink plenty of warm water afterwards; recovery occurs with sweating.
[Note] This formula treats Sun Taiyang pathogenic heat entering the Fu organs, where water qi fails to transform. It addresses the exterior and interior of the Bladder. One type treats Water Reversal (Shuini), where water is vomited upon ingestion; the other treats Thirst Consumption (Xiaoke), where water is consumed immediately. The Bladder is the mansion of fluid essence; it excretes urine only when Qi transformation occurs. Pathogenic heat enters; if water is abundant, it stagnates and accumulates above, Bladder Qi transformation fails, causing difficulty in urination. If heat is abundant, water is consumed by heat, Bladder fluid essence is depleted, also causing difficulty in urination. Vomiting after drinking indicates water exceeds heat; consuming after drinking indicates heat exceeds water. Both syndromes involve difficulty in urination, hence both are managed by this formula. However, it is contraindicated if urination is already normal, to avoid further injuring fluid essence. Thus, Wuling San is not exclusively for treating water-heat but is the primary formula for water-heat causing difficulty in urination. Alisma (Xie) is salty and cold as the Sovereign; saltiness enters the Water Mansion, and coldness overcomes heat pathogens. Poria and Polyporus are bland and permeating as Assistants, regulating water pathways and directing downward to the Bladder, jointly draining water-heat. Atractylodes Macrocephala dries dampness, strengthens the Spleen and assists Earth, acting as a dam to control water. Cinnamon Twig (Guizhi) is pungent and warm, disseminating Yang Qi and vaporizing the Sanjiao to move water. Alisma combined with the two Polypori descends, doubling the urination effect, allowing free urination and preventing water accumulation. Atractylodes Macrocephala combined with Cinnamon Twig ascends, rapidly enhancing Yang dissemination; Qi rises, fluids transform, and thirst stops. If fever and exterior signs persist, use Cinnamon Twig instead of Cinnamon Bark, drink warm water, and recover with sweating. This formula not only treats interior water retention causing difficulty in urination but also resolves exterior heat caused by water retention. Adding Ginseng creates Chunze Tang, focusing on assisting Qi transformation to generate fluids. Adding Artemisia Capillaris creates Yinchen Wuling San, treating damp-heat jaundice with exterior-interior deficiency and difficulty in urination, achieving complete cure.
Guizhi Qu Shaoyao Jia Fuling Baizhu Tang (Cinnamon Twig Decoction Removing Peony plus Poria and Atractylodes Macrocephala) treats cases where, after taking Guizhi Tang or undergoing purgation, there is no stiff pain in the head and neck, low-grade fever, no sweating, fullness and slight pain in the epigastrium, and difficulty in urination. This is treated with Guizhi Qu Shaoyao Jia Fuling Baizhu Tang.
Formula for Guizhi Qu Shaoyao Jia Fuling Baizhu Tang:
In the Guizhi Tang formula, remove Peony and add Poria and Atractylodes Macrocephala, each 3 liang. Prepare and administer according to the Guizhi Tang method. Recovery occurs when urination becomes normal.
[Note] After taking Guizhi Tang, sweating occurred; or after purgation, the bowels were moved. Now there is no exterior sign of stiff pain in the head/neck, low-grade fever, or no sweating. There are interior signs of fullness/slight pain in the epigastrium and difficulty in urination due to retained fluid. If there is no sweating with unresolved exterior and fluid qi in the epigastrium, Xiaolong Tan (Minor Green Dragon Decoction) should be used to induce sweating. However, now there is no sweating with unresolved exterior, fluid qi, epigastric fullness, slight pain, and difficulty in urination, yet Xiaolong Tan is not used because the patient has already undergone sweating and purgation, leaving both exterior and interior deficient. Therefore, Guizhi Tang is still used to release the exterior. Peony's sour astringency is removed to avoid worsening epigastric fullness in the absence of sweating. Poria's drying and draining properties are added because water retention causes difficulty in urination. Preparing according to Guizhi Tang method means inducing sweating via Guizhi Tang protocol. Normal urination indicates recovery as fluid pathology is resolved through water pathways. This formula is essentially Ling Gui Gan Zhu Tang with Ginger and Jujube. Its intent is primarily to release the muscle layer, with water-draining secondary. Thus, Ginger and Jujube assist Cinnamon Twig to unblock fluid essence and induce sweating. Ling Gui Gan Zhu Tang does not use Ginger and Jujube but adds Poria; its intent is primarily water-draining, with Yang-supporting secondary. Thus, Poria is doubled as Sovereign, Cinnamon Twig as Minister, supporting Yang during water-draining. Hence, the post-formula instructions do not say "according to Guizhi Tang."
Shizao Tang (Ten Jujubes Decoction) treats Sun Taiyang Wind Strike where exterior signs have resolved, with sweating but no aversion to cold. Interior water qi is present, causing difficulty in urination, vomiting, shortness of breath, and distending fullness, hardness, and pain from the epigastrium to the hypochondrium. This is an urgent formula for treating water qi.
Jujube (broken, 10 pieces), Kansui, Daphne Genkwa, Euphorbia Lathyris (stir-fried, equal parts).
The above three ingredients are separately pulverized. Boil ten large Jujubes in 1.5 sheng of water until 0.8 sheng remains, strain; add the powder. Strong individuals take 1 qian; weak individuals take 0.5 qian. Take warm on an empty stomach in the morning. If bowel movement is slight and disease persists, repeat the next day, increasing by 0.5 qian. After obtaining profuse purgation, self-nourish with millet gruel.
[Annotations] Ke Qin stated: Zhang Zhongjing's formulas for treating water qi vary greatly; this is the most峻猛 (potent/severe). Generally, water qi pathology manifests locally—coughing, palpitations, choking, vomiting, or diarrhea. Here, however, water evil lingers and knots in the middle, causing distending fullness, hardness, and pain in the heart, abdomen, and hypochondrium, blocking the ascending and descending Qi of the Sanjiao. At this time, exterior pathogens have ceased, making sweating methods inappropriate. Interior fluid retention is substantial, exceeding the capacity of bland-permeating herbs. Without selecting extremely potent water-draining herbs to subdue it, the Middle Qi will collapse, leaving one helpless awaiting death. Kansui, Genkwa, and Euphorbia are all pungent, bitter, and cold, possessing extreme toxicity. Used together, their flavors complement and enhance each other, allowing them to attack the water evil's stronghold directly, opening the waterways for massive purgation, resolving the crisis in one stroke. However, where pathogenic factors gather, Qi must be deficient. Using toxic drugs to eliminate evil inevitably damages the Spleen and Stomach. Therefore, neutral, harmonious, sweet, and緩 (gentle) substances must act as masters. Then, when evil is exhausted, life is preserved. Yet these drugs are highly toxic; Codonopsis and Atractylodes cannot serve as Sovereigns, and Licorice is incompatible. Thus, ten large, plump Jujubes are chosen as Sovereigns: one to protect the Spleen and Stomach, the other to moderate the severe toxicity. After profuse purgation, self-nourishing with millet gruel ensures internal grain Qi fills the body and prevents recurrence of evil. This is Zhang Zhongjing's method of using toxicity to attack disease, perfect in beauty and goodness. Ignorant people, confused by the saying "sweetness causes fullness," dare not use it, failing to understand the principle of restraint and control.
