肝脉入阴。内贯小腹。肾脉贯脊中。络膀胱。两脏并藏。气熏冲脉。自肾下入于胞。
今水不行。故坚而结。然肾主水。水冬冰。水宗于肾。肾象水而沉。名曰石水。因水

趺阳脉当伏。今反紧。本自有寒疝瘕。腹中痛。医反下之。下之即胸满短气。
〔衍义〕趺阳脉当伏者。非趺阳胃气之本脉也。为水蓄于下。其气伏。故脉亦伏。脉

寸口脉弦而紧。弦则卫气不行。紧即恶寒。水不沾流。走于肠间。
〔衍义〕脉弦为水。紧为寒。卫气喜温而恶寒。水寒则卫气无以温分肉。肥腠理。故
恶寒也。然肺者荣卫之主。通调水道。下输膀胱。气化出溺。今卫气不行。即肺之

从郁所化而过于苦。水积于外。其味从湿所化而过于咸。咸味归阴。苦乃从咸
润下。入于胞囊。故阴肿也。如病肾水者。止以咸渗泄。但阴下湿而已。此因苦与
咸相合。苦性坚。因火与水相搏。所以咸味不得渗泄。而结为阴肿矣。
（关于水气病的七条论述、五种脉证、九个方剂）
老师说：疾病有风水、皮水、正水、石水、黄汗这几种。风水病的脉象自然浮，外在症状是骨节疼痛，怕风。皮水病的脉象也浮，外在症状是浮肿，按压后凹陷不起，不怕风，腹部像鼓一样胀满，口不渴，应当用发汗法治疗。正水病的脉象沉迟，外在症状是自然气喘。石水病的脉象自然沉，外在症状是腹部胀满但不喘。黄汗病的脉象沉迟，身体发热，胸部胀满，四肢和头面部浮肿，如果久治不愈，必然导致痈脓。
〔衍义〕所谓风水，是因为肾本属水，因受风邪而导致水液积聚。《内经·大奇病论》说：“脉象并见浮象的是风水。”注解说以浮脉为风水，脉浮说明下焦有水，是水与风搏结于下部，所以叫风水。《素问·水热穴论》说：“肾为至阴之脏，如果人勇力过度或劳倦甚，则肾汗外出，遇到风邪，内不能入脏腑，外不能越肌肤，客留于玄府（汗孔），行于皮肤之间，传变为肿，病根在肾，名叫风水。”《素问·评热病论》说：“肾风，面部肿胀壅塞，言语不利。如果不该刺而误刺，五天后邪气必至。到了之后必然少气、时时发热，热从胸背向上至头部，出汗，手热，口干，小便黄，眼下肿，腹中鸣响，身体沉重，难以转侧，月经不来，心烦不能仰卧，仰卧则咳嗽，名叫风水。”这里只提到外在症状骨节痛、恶风，没有提到肿。因为肾外合于骨，水邪则病骨；肝外合于筋，风邪则束缚筋脉，涉及关节，所以骨节痛。脉浮、恶风，可知风水之证在表。
所谓皮水，是皮肤浮肿。《灵枢》说：“腹胀，是寒气客于皮肤之间，肤肤然不坚，腹部大，全身浮肿，皮肤厚，按腹部，凹陷不起，腹部颜色不变。”巢元方的《诸病源候论》则认为皮水是腹部如故而不渴，这与《灵枢》不同。大概肺主气以运行营卫，外合皮毛。皮病严重，则肺气郁滞，营卫停滞不行。然而肺气之满，不同于其他邪气，气虽然化成水，但本质仍轻清，所以肤肤然不坚，按之没指，腹部也凹陷不起。玄府闭塞所以不怕风，郁火燥其津液所以不渴。应当发汗，以散皮毛之邪，使外气通畅而郁结解除。这就是“开鬼门”的方法。
所谓正水，是肾主水，肾经之水自病。《内经》说：“肾是胃的关口，关口不通利，所以聚水成病，上下溢于皮肤，发生肿胀，上逆则为喘呼不得卧，这是标本俱病。”
所谓石水，是水积在小腹，胞宫内坚硬胀满像石头。《内经》说：“阴阳结邪，阴多阳少，名叫石水。”又说：“肾脉和肝脉都沉，名叫石水。”注解说：“肝脉进入阴部，内贯小腹；肾脉贯穿脊柱，联络膀胱。两脏都是藏精之脏，气熏蒸冲脉，从肾下入于胞。现在水液不行，所以坚硬结聚。然而肾主水，水在冬天结冰，水的根源在肾，肾象水而脉沉，名叫石水。因为水积在胞内，向下从足少阴、手少阴上逆于肺而致喘。”巢氏《病源》说石水引致两胁下胀痛，或者上行至胃脘则死。看来上一条虽同为石水，与此条略有差异。此条偏重于肾气多，肾为阴，阴主静，所以病只在下面而不移动；彼条偏重于肝气多，肝为阳，主动，所以上行克制胃脘。
所谓黄汗，是病水，身体发黄，汗出像柏树汁一样。后面的条文各种症状各有成因，原因不一。大致黄色属土，由阳明胃热所致，所以色见于外。现在的发热、胸满、四肢头面肿，正是足阳明经脉的证候。热久在肌肉，所以化生痈脓。如果巢氏所说，疸水因脾胃有热，流于膀胱，小便涩而身面大黄，腹满如水状，这也是黄汗的一种。
脉象浮而洪，浮则为风，洪则为气。风气和气相搏，风强则为瘾疹，身体瘙痒，痒者为泄风，久了成为痂癞。气强则为水，难以俯仰。风气和气相互搏击，身体洪大浮肿，出汗就好了。怕风的则是虚，这叫风水。不怕风的，小便通利，上焦有寒，口中多涎，这叫黄汗。
〔衍义〕风是外感的风邪，气是营卫之气。风是阳邪，从上受之，所以脉浮。营卫得风而热，所以脉洪。洪就是大。《内经》说：“脉大则病进”，是由于邪气盛。营行脉中主血，卫行脉外主气。风强，是风得热而强。风热侵入搏结于卫分，客于皮里，气滞郁聚而被风鼓动，形成瘾疹。火又助风，腠理开，毫毛摇，则身体痒。痒为泄风。《内经》说：“诸痛疮疡，皆属于火。”又说：“风气外在腠理，则为泄风。”久了不解，风入分肉间，相搏于脉之内外，气道涩而不利，与卫相搏，则肌肉溃烂而生疮。风入脉中，内攻营血，风气合热而血坏，遂成为痂癞。《内经》说：“风气与太阳俱入，行诸脉俞，散于分肉之间，与卫气相干，其道不行，使肌肉䐜（chēn，肿胀）而有疡。”又说：“脉风成厉，厉即癞也。”
所谓气强，是卫因热则怫郁，停而不行。气水同类，气停则水生，所聚的液血都化为水。不仅营卫不和，筋骨肌肉郁热之邪，且被禁固，难俯仰。至于风气复行相击，营卫之热与水，皆散溢于肌表，而为洪肿。及风气两解，则水散卫行，汗出乃愈。
怕风的，是不敌于风，与水同为汗散而表虚，因名风水。不怕风的，卫气不从汗散，外能固护腠理，则不怕风而得固护上焦，则小便通利。所谓上焦有寒，是因为风邪在上焦，并非真有寒冷。如伤寒证邪客上焦，则中焦的谷气，不得上输于肺，郁为内热，津液凝积为胃热，热则廉泉开。廉泉是津液之道，开则发，涎出流于唇口。此黄汗由身倦浮肿，胃热发出土色。
寸口脉沉滑者，中有水气，面目肿大，有热，名叫风水。看人的目窠上，微肿如蚕新卧起的样子，颈脉搏动，时时咳嗽，按手足上，陷而不起的，是风水。
〔衍义〕《内经脉》说脉沉曰水，脉滑曰风。面肿曰风，目肿如新卧起之状曰水，颈脉动喘咳曰水。又有肾风，面庞然，少气时热，其有浮肿者，亦曰本于肾，名风水，都出自《内经》。
太阳病，脉浮而紧，法当骨节疼痛，反而不疼，身体反而重而酸，其人不觉渴，汗出即愈，此为风水。怕冷的，此为极虚，是发汗不当导致的。渴而不怕风的，此为皮水。身体肿而冷，状如周痹，胸中窒塞，不能食，反聚痛，傍晚烦躁不得眠，此为黄汗。骨节痛，咳而喘，不渴的，此为肺胀。其状如肿，发汗则愈。然而各种病有此表现的，如果口渴且下利，小便频数的，都不可发汗。
〔衍义〕《伤寒论》说，脉浮而紧者，为风寒。风伤卫，寒伤荣，荣卫俱病。荣卫是由胃的谷气化生的，从手太阳所出，循行表里，在外则荣筋骨，温皮肉，在内则贯五脏，络六腑，所以浮沉变脉，皆见于寸口。此条首言太阳病脉紧为太阳属表，荣卫所受风水，随在诸经四属，隶于太阳之表者，分出六等。于肝脏所合，则骨节痛；若风水挟木克土，脾合肌肉，则肌肉不利，骨节反不痛，身体重而酸。《内经》说：“土不及，则体重而筋肉酸也。”因不渴则可发汗，汗则邪散乃愈。此由风胜水也，亦名风水。其汗皆生于气，气生于精，精气若不足，辄发其汗，风水未散，而荣卫之精，先从汗散，遂致虚极，不能温腠理，故恶寒也。若发汗用辛热之味，上冲于肺，亡其津液，则肺燥而渴，荣卫不虚，则不恶寒。风水之邪，从肺虚风入，并于所合之皮毛，遂为皮水。皮水久不解，荣卫与邪并，外不得温分肉，至于身肿冷，状如周痹，内窒胸膈，脾胃气郁成热，故不能食，胃热复上，与外入之水寒相击，故痛聚胸中，暮躁不得眠也。脾土之色发于外，是为黄汗。若骨节疼痛而浮肿者，是肾之候也。咳而喘者，是肺之候也。二病俱见，由肾脉上贯肝入肺，乃标本俱病。言脾胀，恐是肺字之误。《灵枢》说：“肺是动病则肺胀满，膨膨而喘，咳是也。”然病虽更改不动，尽属在表，故浮紧之脉，皆得汗之，但渴与下利小便数亡津液者，不可汗耳。
里水病，一身面目黄肿，脉沉，小便不利，所以令病水。假如小便自利，这是亡津液，所以令渴。用越婢加术汤主治。（方剂见中风篇）
〔衍义〕《内经》说三阴结谓之水。三阴乃脾、肺、少阴肾也。大概胃为五脏六腑之海，十二经皆受气焉，脾为之行津液者，脏腑经络，必因脾，乃得禀水谷气。今脾之阴不与胃之阳和，则阴气结伏，津液凝聚不行，而关门闭矣。关闭则小便不利，不利则水积，积则溢，面目一身，水从脾气所结，不与胃和，遂从土色发黄肿。结自三阴，故曰里水，其脉沉也。如小便自利，则中上焦之津液，从三阴降下而亡，故渴也。是汤见后。
趺阳脉本当伏，现在反而紧，本来自有寒疝瘕，腹中痛，医生反而用下法，下之即胸满短气。
〔衍义〕趺阳脉当伏者，非趺阳胃气之本脉也，为水蓄于下，其气伏，故脉亦伏。脉法说：“伏者为水，急者为疝瘕，小腹痛。”脉当伏而反紧，知其初有寒疝瘕痛。先病者治其本，先当温其疝瘕，治寒救阳而后行，可也。若反下之，是重虚在上之阳，阳气不布化，而成胸满短气也。
趺阳脉本当伏，现在反而数，本来自有热，消谷，小便数，现在反而不利，此欲作水。
〔衍义〕此与上条一寒一热，互举其因。此为热消谷，不能上化精微，热浊下流，致膀胱不化，小便蓄成积水，故脉不伏而从热反数也。
寸口脉浮而迟，浮脉则热，迟脉则潜。热潜相搏，名叫沉。趺阳脉浮而数，脉浮即热，数脉即止。热止相搏，名叫伏。沉伏相搏，名叫水。沉则络脉虚，伏则小便难。虚难相搏，水走皮肤，即为水矣。
〔衍义〕寸口、趺阳合诊是什么？寸口是肺脉所过，趺阳是胃之所过。候脾肺合病，必是二处。寸口脉浮而迟，浮脉即热的是什么？浮为卫，卫为阳，卫不与荣和，其阳独在脉外，故浮脉即热矣。迟脉即潜的是什么？迟为荣，荣、阴也，荣不从卫，匿行脉中，阴行迟，故迟脉即潜矣。热潜相搏，名叫沉的是什么？脉者气藏也，荣卫之出阳入阴，乃皆肺脏主之，故百脉朝之也。今荣卫不和，热潜之邪相搏而至，则肺脏之气不得布，故结而沉矣。
趺阳脉浮而数，浮脉即热的是什么？脾土中焦，与胃为表里，脾、阴也，胃、阳也，脾与胃行津液化血者也。胃经之阳，不与脾经之阴合，失阴之阳独在表，故脉浮即热矣。数脉即止的是什么？脉者血之府，血阴也，血实则脉实，阴失则脉缓。今脾经之阴血虚不足，脉被气促而数，数则阴血不得周流于脉，故脉数即止矣。热止相搏，名叫伏的是什么？藏之于经，表里相资者也。脏在里，以藉经脉之运动。今二经以热止之邪相搏，名叫水的是什么？脾肺，手足太阴经之脏也。夫阳为火，阴为水，今手足两太阴持，所结沉伏之阴相搏，故化为水矣。《内经》说：“三阴结为水也。”
沉则络脉虚的是什么？肺合皮毛，络脉之在皮肤者，因肺气沉，不发于外，荣血又潜，不入于内，络脉虚矣。伏则小便难的是什么？小便以通行津液，今脾气复不为胃行津液，则津液不入膀胱，故小便难矣。虚难相搏，水走皮肤，即为水的是什么？小便难则水积，积则溢，溢则乘络脉之虚，而走注于皮肤，故水病矣。在内经则曰：“三阴结谓之水。”仲景则举经络荣卫之变而条析之，以核病之源，察脉论证，其可不究心而消息之乎？
寸口脉弦而紧，弦则卫气不行，紧即恶寒，水不沾流，走于肠间。
〔衍义〕脉弦为水，紧为寒。卫气喜温而恶寒，水寒则卫气无以温分肉，肥腠理，故恶寒也。然肺者荣卫之主，通调水道，下输膀胱，气化出溺。今卫气不行，即肺之治节不行，治节不行，则输化之职废，故不得沾流水道，反走肠间。肠、大肠也，大肠与肺合。若上条之走皮肤，皮肤亦肺所主，二者对出，以明肺之不调，则随其所属而为病耳。
少阴脉紧而沉，紧则为痛，沉则为水，小便即难。脉得诸沉，当责有水，身体肿重，水病脉出者死。
〔衍义〕脉可一法取之乎？不可也。此脉沉有水，脉出为死者，是脉不可出而浮大也。试以气强为水者观之，非脉之浮大者乎？而风水皮水脉皆浮，怀孕妇病水亦浮，水病岂独取沉脉为例哉？此条之论，盖独为少阴病水耳。少阴者，至阴盛水也，合四时主冬，故脉沉，水之象当然也，少阴经气当然也，当沉，故不可出，出则少阴经气外绝，死之征矣。凡言浮沉迟数之脉，为其各有所由，故不可以一法取之也。虽然，肾脏独病，其水则沉，兼风则不沉。所为出者，非独为浮也，为经气离出其脏，沉之亦无有也。
凡是水病患者，目下有卧蚕，面目鲜泽，脉伏，其人消渴，病水，腹大，小便不利，其脉沉绝者有水，可下之。
〔衍义〕《内经》说色泽者，病溢饮。溢饮者，渴而多饮，易入肌皮肠胃之外。注云：是血虚中湿。又说：水、阴也，目下亦阴也，腹者至阴之所居也，故水在腹，便目下肿也。《灵枢》说：“水始起也，目下微肿如蚕，如新卧起之状。”其人初由水谷不化津液，以成消渴，必多饮，多饮则水积，水积则气道不宣，故脉浮矣。所积之水，溢于肠胃之郭，则腹大，三焦之气不化，则小便难。若脉沉绝者，知其水积在内已甚，脉气不发故也。必下其水，乃可愈。
问曰：病下利后，渴饮水，小便不利，腹满阴肿者，何也？答曰：此法当病水，若小便自利，及汗出者，自当愈。
〔衍义〕下利血虚液少，故渴，渴而暴饮，水停不散，故小便不利，溢于内外，以成肿满，故小便利而汗出，则所停之水行，而肿满愈矣。
心水病，其身重而少气，不得卧，烦而躁，其人阴肿。
〔衍义〕心、君火也，其气蕃茂，遇寒水则屈伏。今水客于心，火气郁蕃，不得发于分肉，则身重，不充盛于气海，则少气，烦热内作，则躁而不得眠也。火气不舒，其味从郁所化而过于苦，水积于外，其味从湿所化而过于咸，咸味归阴，苦乃从咸润下，入于胞囊，故阴肿也。如病肾水者，止以咸渗泄，但阴下湿而已，此因苦与咸相合，苦性坚，因火与水相搏，所以咸味不得渗泄，而结为阴肿矣。
(Seven discussions, five pulse and symptom patterns, nine formulas regarding Water Qi Disease)
The Master said: Diseases include Fengshui (Wind Edema), Pishui (Skin Edema), Zhengshui (Standard Edema), Shishui (Stone Edema), and Huanghan (Yellow Sweat). The pulse of Fengshui is naturally floating; its external symptoms are joint pain and aversion to wind. The pulse of Pishui is also floating; its external symptoms are edema that leaves an indentation upon pressure, aversion to wind is absent, the abdomen is distended like a drum, there is no thirst, and sweating therapy should be employed. The pulse of Zhengshui is deep and slow; its external symptom is spontaneous wheezing. The pulse of Shishui is naturally deep; its external symptom is abdominal fullness without wheezing. The pulse of Huanghan is deep and slow, accompanied by fever, chest fullness, and edema of the limbs, head, and face. If it persists for a long time without healing, it will inevitably lead to carbuncles and pus.
[Commentary] "Fengshui" refers to water accumulation due to wind invasion, as the Kidney fundamentally belongs to Water. *Neijing* (Classic of Internal Medicine) · Daqi Binglun states: "Simultaneous floating indicates Fengshui." The commentary notes that a floating pulse indicates Fengshui; a floating pulse in the lower jiao indicates water and wind battling below, hence named Fengshui. *Suwen* · Shuire Xuelun states: "The Kidney is the organ of extreme Yin. If one exerts oneself vigorously or labors excessively, Kidney sweat emerges. If encountered by wind, it neither enters the zang-fu internally nor escapes the skin externally, but lodges in the xu fu (pores), travels within the skin, and transforms into swelling. Rooted in the Kidney, it is named Fengshui." *Ping Re Binglun* states: "Renfeng presents with facial swelling and obstruction of speech. If needling is performed inappropriately, after five days the pathogenic qi will arrive. Upon arrival, there will be shortness of qi and intermittent fever, with heat rising from the chest and back to the head, sweating, hot hands, dry mouth, yellow urine, edema under the eyes, borborygmus, heavy body, difficulty turning, amenorrhea, irritability preventing supine position, and coughing when supine. This is named Fengshui." Here, only external symptoms of joint pain and aversion to wind are mentioned, not edema. Since the Kidney corresponds to bones externally, water pathology affects the bones; the Liver corresponds to sinews externally, and wind binds the sinews involving joints, causing joint pain. A floating pulse and aversion to wind indicate that the Fengshui syndrome is at the exterior.
"Pishui" refers to skin edema. *Ling shu* states: "Abdominal distension occurs when cold qi lodges between the skin. The abdomen is soft but not firm, large, with whole-body edema and thick skin. Pressing the abdomen leaves an indentation that does not rise immediately, while the abdominal color remains unchanged." Chao Yuanfang's *Zhubing Yuanhou Lun* considers Pishui as having an unaltered abdomen and no thirst, differing from *Ling shu*. Generally, the Lung governs qi to circulate Ying and Wei, corresponding externally to the skin and hair. Severe skin disease causes Lung qi stagnation, leading to stagnation of Ying and Wei circulation. However, Lung qi fullness differs from other pathogens; although qi transforms into water, its origin is light and clear, hence the soft, non-firm texture, indentation upon pressure, and abdominal depression. Closure of xu fu prevents aversion to wind, while stagnant fire dries fluids causing no thirst. Sweating therapy should be used to disperse exterior pathogens, allowing exterior qi to flow freely and resolving stagnation. This is the method of "opening the ghost gate" (diaphoresis).
"Zhengshui" refers to the Kidney governing water, where water pathology originates in the Kidney meridian. *Neijing* states: "The Kidney is the gate of the Stomach. If the gate is obstructed, water accumulates to cause disease, overflowing up and down into the skin, causing swelling. Ascending causes wheezing and inability to lie flat, indicating both root and branch are diseased."
"Shishui" refers to water accumulation in the lower abdomen, where the bladder interior is hard and full like stone. *Neijing* states: "Yin and Yang bind evil, with Yin predominating over Yang, named Shishui." It also states: "Simultaneous deep pulses of the Kidney and Liver indicate Shishui." Commentary explains: "The Liver meridian enters the yin regions and penetrates the lower abdomen; the Kidney meridian passes through the spine and connects with the Bladder. Both organs store essence, and their qi steams the Chong mai, entering the bladder from below. When water fails to move, it becomes hard and knotted. Since the Kidney governs water, and water freezes in winter, with its source in the Kidney, the Kidney resembles water and has a deep pulse, hence named Shishui. Due to water accumulation in the bladder, it reverses upward along the Foot-Shaoyin and Hand-Shaoyin meridians to the Lung, causing wheezing." *Zhubing Yuanhou Lun* states Shishui causes distending pain in the hypochondrium, potentially ascending to the epigastrium leading to death. Comparing this with the previous paragraph, although both are Shishui, they differ slightly. This case emphasizes Kidney qi more; the Kidney is Yin, Yin is static, so the disease remains lower without moving. The other case emphasizes Liver qi more; the Liver is Yang, Yang is active, so it ascends to attack the epigastrium.
"Huanghan" is a water disease where the body turns yellow and sweat resembles paulownia juice. Subsequent paragraphs describe various causes. Generally, yellow corresponds to Earth, resulting from Yangming Stomach heat, manifesting externally. Current symptoms of fever, chest fullness, and edema of limbs, head, and face belong to the Foot-Yangming meridian. Heat lingering in muscles generates carbuncles and pus. As stated in *Zhubing Yuanhou Lun*, Dan-shui (Jaundice-Water) arises from Stomach-Spleen heat flowing to the Bladder, causing difficult urination, yellow body/face, and abdominal fullness resembling water status; this is also a type of Huanghan.
A pulse that is floating and surging indicates floating signifies wind, and surging signifies qi. Wind and qi battle each other. If wind dominates, it causes urticaria (itchy rash) and body itching; chronic itching leads to scabies-like lesions. If qi dominates, it causes water retention and difficulty bending or stretching. Mutual combat of wind and qi causes massive edema; recovery occurs through sweating. Aversion to wind indicates deficiency, termed Fengshui. Absence of aversion to wind with free urination and cold in the upper jiao causing excessive saliva indicates Huanghan.
[Commentary] Wind refers to external wind pathogens, and qi refers to Ying-Wei qi. Wind is a Yang pathogen entering from above, causing a floating pulse. Ying-Wei become heated by wind, causing a surging pulse (large). *Neijing* states: "Large pulse indicates disease progression" due to pathogenic excess. Ying circulates within vessels governing blood; Wei circulates outside governing qi. Strong wind implies wind strengthened by heat. Wind-heat battles Wei, lodging beneath the skin, causing qi stagnation and wind agitation, forming urticaria. Fire assists wind, opening pores and shaking hairs, causing itching. Itching is "Xiefeng" (leaking wind). *Neijing* states: "All painful sores and ulcers belong to fire," and "External wind in collaterals causes Xiefeng." If unresolved, wind enters muscle layers, battling inside and outside vessels, obstructing qi flow, battling Wei, causing muscle ulceration. Wind entering vessels attacks Ying blood; wind-heat damages blood, leading to scabies. *Neijing* states: "Wind and Taiyang enter together, traveling through acupoints, scattering between muscles, interfering with Wei qi, blocking pathways, causing muscle swelling and ulcers." Also: "Pulse wind becomes leprosy."
Strong qi means Wei qi is constrained by heat, stopping movement. Qi and water are similar; stopped qi generates water, transforming accumulated fluids and blood into water. Not only do Ying and Wei fail to harmonize, but heat in sinews, bones, and muscles is constrained, causing difficulty bending/stretching. When wind and qi continue to battle, Ying-Wei heat and water scatter to the surface, causing massive edema. When wind and qi resolve, water disperses, Wei moves, and sweating brings recovery. Aversion to wind indicates inability to resist wind, with water and sweat dispersing together, causing exterior deficiency, hence Fengshui. No aversion to wind means Wei qi does not disperse via sweat, securing pores and protecting the upper jiao, ensuring free urination. "Cold in upper jiao" refers to wind pathogen in the upper jiao, not actual cold. In Shanghan, if pathogen lodges in upper jiao, middle jiao grain qi cannot ascend to the Lung, becoming internal heat, condensing fluids into Stomach heat. Heat opens Lianquan (gateway of fluids), causing saliva flow. This Huanghan results from fatigue, edema, and Stomach heat emitting Earth color.
Cunkou pulse deep and slippery indicates internal water qi, swollen face and eyes, fever, named Fengshui. Observing slight swelling of the eye sockets like newly awakened sleepers, pulsating neck vessels, frequent coughing, and pitting edema on hands/feet indicates Fengshui.
[Commentary] *Inner Meridian Pulse* states deep pulse indicates water, slippery indicates wind. Facial swelling indicates wind, eye swelling like new awakening indicates water, pulsating neck with wheezing/cough indicates water. Renfeng presents with facial swelling, shortness of qi, intermittent fever; with edema, rooted in Kidney, named Fengshui, all from *Neijing*.
Taiyang disease with floating-tight pulse typically causes joint pain. If pain is absent but body feels heavy and sore, without thirst, sweating cures it; this is Fengshui. Aversion to cold indicates extreme deficiency caused by improper sweating. Thirst without aversion to cold indicates Pishui. Body edema with cold sensation resembling Zhoubi (circumferential bi), chest oppression, inability to eat, gathering pain, evening restlessness, and insomnia indicate Huanghan. Joint pain, cough, wheezing, and no thirst indicate Feizhang (Lung Distension). Appearance resembles edema; sweating cures it. However, for diseases with these signs, if accompanied by thirst, diarrhea, and frequent urination, sweating is contraindicated.
[Commentary] *Shanghan Lun* states floating-tight pulse indicates Wind-Cold. Wind injures Wei, Cold injures Ying, affecting both. Ying-Wei are transformed from Stomach grain qi, originating from Hand-Taiyang, circulating interior/exterior, nourishing sinews/bones, warming skin/flesh externally, connecting five zang/six fu internally. Thus, floating/deep pulses appear at Cunkou. This paragraph begins with Taiyang disease, tight pulse indicating exterior location. Ying-Wei affected by Fengshui distribute through meridians subordinate to Taiyang exterior. Corresponding to Liver, joint pain occurs; if Fengshui involves Wood attacking Earth, Spleen governs muscles, causing muscle dysfunction, absent joint pain, heavy/sore body. *Neijing* states: "Earth deficiency causes heavy body and sore muscles." Absence of thirst allows sweating to disperse pathogens. This is Wind overcoming Water, also named Fengshui. Sweat is generated by qi, qi by essence. If essence/qi is insufficient, sweating depletes Ying-Wei essence before Fengshui disperses, causing extreme deficiency and inability to warm pores, leading to aversion to cold. If pungent-hot herbs ascend to Lung, destroying fluids, Lung dries causing thirst; if Ying-Wei are not deficient, no aversion to cold. Fengshui pathogen enters Lung deficiency via wind, combining with skin/hair, becoming Pishui. Chronic Pishui combines Ying-Wei with pathogen, failing to warm flesh, causing cold edema resembling Zhoubi, internal chest oppression, Spleen-Stomach qi stagnation generating heat, causing anorexia. Stomach heat rises, battling external cold-water, causing chest pain, evening restlessness. Spleen Earth color emits externally as Huanghan. Joint pain with edema indicates Kidney sign; cough/wheezing indicates Lung sign. Both present due to Kidney meridian passing through Liver to Lung, affecting root and branch. "Pi Zhang" is likely a typo for "Fei Zhang." *Ling shu* states: "Lung movement disease causes Lung distension, bloating, wheezing, cough." Although conditions change, they remain exterior; thus floating-tight pulses respond to sweating, except when thirst, diarrhea, or frequent urination indicate fluid depletion.
Li Shui (Interior Water) presents with yellow edema of face/body, deep pulse, difficult urination, causing water disease. If urination is normal, fluid depletion causes thirst. Yuebi Jia Zhu Tang is indicated. (Formula see Wind Stroke section).
[Commentary] *Neijing* states binding of Three Yin causes water. Three Yin are Spleen, Lung, Shaoyin Kidney. Stomach is sea of zang-fu, receiving qi from twelve meridians. Spleen transports fluids; zang-fu/meridians rely on Spleen to receive grain qi. If Spleen Yin does not harmonize with Stomach Yang, Yin qi binds, fluids condense and stop, closing the gate. Closed gate causes difficult urination, water accumulation, overflow causing yellow edema. Binding in Three Yin is called Li Shui, with deep pulse. Normal urination drains fluids from Three Yin, causing thirst. Formula follows.
Duyang pulse should be hidden but is now tight. Originally suffering from Han Shan (Cold Hernia) and Jia (masses) with abdominal pain, the physician incorrectly used purgatives, causing chest fullness and shortness of qi.
[Commentary] Duyang pulse should be hidden because water accumulates below, hiding qi, thus pulse is hidden. Pulse methods state: hidden indicates water, rapid/tight indicates hernia/masses, lower abdominal pain. Hidden pulse turning tight indicates initial Cold Hernia/Masses pain. Treat root first: warm Hernia/Masses, treat cold, save Yang, then proceed. Incorrect purgation further deficiences upper Yang, preventing distribution, causing chest fullness/shortness of qi.
Duyang pulse should be hidden but is now rapid. Originally having heat, digesting food quickly, frequent urination, now urination is difficult, indicating impending water disease.
[Commentary] Contrasts cold and heat causes. Heat digests food but fails to transform nutrients upward; turbid heat flows down, impairing Bladder transformation, accumulating urine/water, causing rapid pulse instead of hidden.
Cunkou pulse floating and slow. Floating indicates heat, slow indicates submersion. Heat and submersion battle, named Chen (Sinking). Duyang pulse floating and rapid. Floating indicates heat, rapid indicates cessation. Heat and cessation battle, named Fu (Hidden). Sinking and Hidden battle, named Water. Sinking makes collaterals empty; Hidden makes urination difficult. Empty and difficult battle, water flows to skin, becoming water disease.
[Commentary] Combined diagnosis of Cunkou and Duyang. Cunkou is Lung pulse; Duyang is Stomach pulse. Diagnosing Spleen-Lung combined disease requires both. Cunkou floating-slow: floating indicates Wei/Yang not harmonizing with Ying, Yang alone outside vessel, hence heat. Slow indicates Ying/Yin not following Wei, hiding in vessel, Yin moves slowly, hence submersion. Heat/submersion battle causes Lung qi to bind and sink. Duyang floating-rapid: Spleen/Stomach are interior-exterior pair. Stomach Yang not harmonizing with Spleen Yin, Yang alone exterior, hence heat. Rapid indicates blood deficiency failing to circulate, hence cessation. Heat/cessation battle causes Hidden pulse. Spleen/Lung are Hand-Foot Taiyin. Yang is Fire, Yin is Water. Taiyin binding causes sinking/hidden Yin to battle, transforming into water (*Neijing*: Three Yin binding causes water). Sinking makes skin collaterals empty (Lung governs skin, Lung qi sinks, Ying blood hides, collaterals empty). Hidden makes urination difficult (Spleen fails to transport fluids to Bladder). Empty/difficult battle causes water overflow to skin, resulting in water disease. *Neijing* says Three Yin binding causes water; Zhang Zhongjing analyzes Jingluo/Ying-Wei changes to trace disease source. One must study pulse and symptoms carefully.
Cunkou pulse wiry and tight. Wiry indicates Wei qi obstruction; tight indicates aversion to cold. Water fails to flow normally, moving into intestines.
[Commentary] Wiry pulse indicates water, tight indicates cold. Wei qi prefers warmth, dislikes cold. Cold water prevents Wei qi from warming flesh and plumping pores, causing aversion to cold. Lung governs Ying-Wei and regulates water passages, transmitting to Bladder. Wei qi obstruction means Lung regulation fails, disrupting fluid transport, causing water to divert to intestines (Large Intestine, paired with Lung). Like previous text describing water in skin (also Lung governed), this shows Lung dysregulation causes disease in its associated areas.
Shaoyin pulse tight and deep. Tight indicates pain; deep indicates water, making urination difficult. Deep pulses generally indicate water, with heavy body edema. If water disease pulse emerges (becomes floating/large), it indicates death.
[Commentary] Can pulse be judged by one method? No. Deep pulse indicates water; emerging pulse indicates death (pulse should not be floating/large). Consider "Qi strong causes water"—is it not floating/large? Fengshui/Pishui pulses float; pregnant women with water disease also have floating pulses. Why restrict water disease to deep pulse? This paragraph specifically addresses Shaoyin water disease. Shaoyin is extreme Yin/Water, governing Winter, hence deep pulse is natural image and meridian qi. Should be deep; if emerging, Shaoyin meridian qi severs externally, indicating death. Floating/deep/slow/rapid pulses have specific causes; cannot use single method. Although isolated Kidney disease has deep water pulse, combined with wind it is not deep. "Emerging" means meridian qi leaving the zang, even deep pulse disappears.
Water patients present with silkworm-like swelling under eyes, bright complexion, hidden pulse, polydipsia, abdominal distension, difficult urination. Deep/absent pulse indicates significant internal water; purgation may be used.
[Commentary] *Neijing* states luster indicates Yi Yin (overflowing water). Yi Yin involves thirst, excessive drinking, water entering muscles/skin/intestines. Note: Blood deficiency with dampness. Water/Yin, under-eye/Yin, abdomen/Yin residence. Water in abdomen causes under-eye swelling. *Ling shu* states early water shows slight under-eye swelling like new awakening. Initial failure to transform fluids causes polydipsia; excessive drinking accumulates water, blocking qi, causing floating pulse. Accumulated water overflows intestines, causing abdominal distension. Sanjiao qi fails to transform, causing difficult urination. Deep/absent pulse indicates severe internal water accumulation with suppressed pulse qi. Purge water to cure.
Question: After diarrhea, patient drinks water, has difficult urination, abdominal distension, and genital edema. What is this? Answer: This should be water disease. If urination becomes free and sweating occurs, it will heal spontaneously.
[Commentary] Diarrhea causes blood/fluid deficiency, leading to thirst. Excessive drinking stops water, causing difficult urination and overflow edema. Free urination and sweating allow stopped water to move, resolving edema.
Xin Shui (Heart Water) presents with heavy body, shortness of qi, inability to lie flat, irritability, and genital edema.
[Commentary] Heart is Minister Fire, vigorous qi. Encountering cold water, it suppresses. Water invading Heart郁stagnates Fire qi, unable to emit to muscles, causing heaviness. Failing to fill Qi Sea, causing shortness of qi. Internal irritability causes restlessness and insomnia. Unsoothed Fire qi transforms bitter taste; external water accumulation transforms salty taste. Salty enters Yin; Bitter descends with Salt into bladder, causing genital edema. Kidney water disease uses salty diuretics causing only lower dampness. Here, Bitter and Salt combine; Bitter is solidifying. Fire-Water battle prevents Salt diuresis, knotting into genital edema.
