三消之病，自古大抵主肾虚为论，往往于肾虚证中，更立名称，盖以其自下消波及者居多也。但上消、中消
之治，则河间、东垣庶得经旨，而上消一证颇为罕有已。今采集诸家方说，不能判然区析，姑并合为条，以俟学
者审别焉。
病由肾虚 消HT 。HT ，渴也。肾气不周于胸胃中，津润消渴，故欲得水也。（《释名》）
凡人生放恣者众，盛壮之时，不自慎惜，快情纵欲，极意房中，稍至年长，肾气虚竭，百病滋生，又年少惧
不能房，多服石散，真气既尽，石气孤立，惟有虚耗，唇口干焦，精液自泄，或小便赤黄，大便干实，或渴而且
利，日夜一石，或渴而不利，或不渴而利，所食之物皆作小便，此皆由房室不节之所致也。（《千金》）（按∶巢
氏论消渴分为消渴、渴病、渴利、内消，其渴病以为脏腑由虚实而生热，津液竭少故渴，而不审何证，其他则谓
为少服五石，热结于肾所致。然服石今世所无，仍仅拈其证于后款，余不具载。）
《近效》祠部李郎中论曰∶消渴者，原其发动，此则肾虚所致，每发即小便至甜。医者多不知其疾，所以古
方论亦阙而不言，今略陈其要。按《洪范》稼穑作甘，以物理推之，淋饧醋酒作脯法，须臾即皆能甜也，足明人
食之后，滋味皆甜。流在膀胱，若腰肾气盛，则上蒸精气，气则下入骨髓，其次以为脂膏，其次为血肉也，其余别
为小便。故小便色黄，血之余也，臊气者，五脏之气；咸润者，则下味也。（按∶此五句，《圣惠》作上余为涕泪，
经循五脏百脉，下余为小便，黄者血之余也，臊者五脏之气，咸者润下之味也。）腰肾既虚冷，则不能蒸于上，谷
气则尽下为小便者
也。故甘味不变，其色清冷，则肌肤枯槁也。犹如乳母，谷气上泄，皆为乳汁。消渴疾者，下泄为小便，此皆精
气不实于内，则使羸瘦也。又肺为五脏之华盖，若下有暖气，蒸即肺润。若下冷极，即阳气不能升，故肺
干则热。故周易有否卦，干上坤下，阳阻阴而不降，阴无阳而不升，上下不交，故成痞也。譬如釜中有水，以火暖
之，其釜若以板盖之，则暖气上腾，故板能润也。若无火力，水气则不上，此板终不可得润也。火力者，则为腰
肾强盛也，常须暖将息。其水气即为食气，食气若得暖气，即润上而易消下，亦免干渴也。是故张仲景云∶宜服此
八味肾气丸，并不食冷物及饮冷水，今亦不复渴。比频得效，故录正方于后耳。（《外台》）
消渴之疾，皆起于肾，盛壮之时，不自保养，快情纵欲，饮酒无度，喜食脯炙 醢，或服丹石，遂使肾水枯
竭，心火燔炽，三焦猛烈，五脏干燥，由是渴利生焉。（《济生》）
天一生水，肾实主之。膀胱为津液之腑，所以宣行肾水，上润于肺。故识者以肺为津液之脏，自上而下，三焦脏
腑，皆囿乎天一真水之中，《素问》以水之本在肾、末在肺者此也。真水不竭，安有所谓渴哉。人惟淫欲恣情，
酒面无节，酷嗜炙 糟藏、咸酸酢醢、甘肥腥 之属，复以丹砂五石济其私，于是炎火上熏，腑脏生热，燥气炽
盛，津液干焦，渴引水浆而不能自禁矣。（《直指》）
盖肾之所主者水也，真水不竭，自足以滋养乎脾而上交于心，何至有干枯消渴之病乎。惟肾水一虚，则无以制
余火，火旺不能扑灭，煎熬脏腑，火因水竭而益烈，水因火烈而益干，阳盛阴衰，构成此症，而三消之患始剧矣，其
根源，非本于肾耶。（《玉案》）
病由饮酒 凡积久饮酒，未有不成消渴。然则大寒凝海
而酒不冻，明其酒性酷热，物无以加。脯炙盐咸，此味酒客耽嗜，不离其口，三HT 之后，制不由己，饮啖无度，
咀嚼 酱HT 觞不择酸咸，积年长夜，酣兴不解，遂使三焦猛热，五脏干燥，木石犹且焦枯，在人何能不渴。治之愈
否，属在病者。若能如方节慎，旬月而瘳∶不自爱惜，死不旋踵。方书医药实多有效，其如不慎者何。（《千金》）
脉候 消渴，脉数大者生，细小浮短者死。消渴，脉沉小者生，实坚大者死。（《脉经》）
三消之脉，浮大者生，细小微涩，形脱可惊。（《删补四言举要》）
消证，脉显实大，为证脉相符，虽久可治。若见悬小而坚，不但脉不应病，且真藏发露，其可疗乎。设消证
脉小，而不至于虚悬坚劲，又当从仲景肾气丸正治矣。然历诊消瘅之脉，无有不带数象者，但须察浮数沉数，在左
在右，尺甚寸甚，及有余不足，兼见何脉而为审治。又须详南北风土之强弱，病患禀气之浓薄，合脉象而推之，庶
几无虚虚之误矣。（《医通》）
三消燥热太过之候，脉宜实大洪滑，为可治；若涩而且微，真阴已竭，多不可救。（《医级》）
三消形证 夫消渴者，渴不止，小便多是也。渴利者，随饮小便故也。内消病者，不渴而小便多是也。
（《病源论》）（按∶此皆下消，《三因》曰消肾，亦曰内消。）
有人病渴利，始发于春，经一夏服栝蒌、豉汁得其力，渴渐瘥，然小便犹数甚，昼夜二十余行，常至三四升，
极瘥不减二升也。转久便止，渐食肥腻，日就羸瘦，喉咽唇口焦燥，吸吸少气，不得多语，心烦热，两脚酸，食乃
兼倍于常，故不为气力者，然此病皆由虚热所为耳。治法栝蒌汁可
长将服以除热，牛乳、杏酪善于补，此法最有益。（《千金》）（按∶此证与次证俱同于巢源所云，亦即下消。）
寻夫内消之为病，当由热中所作也。小便多于所饮，令人虚极短气。夫内消者，食物消作小便也，而又不渴
云云。此病虽稀，甚可畏也。利时脉沉细微弱，服枸杞汤即效。（同上）（枸杞汤见后）
《古今录验》论消渴病有三∶一渴而饮水多，小便数，无脂似麸片甜者，皆是消渴病也。二吃食多，不甚渴，
小便少，似有油而数者，此是消中病也。三渴饮水不能多，但腿肿脚先瘦小，阴痿弱，数小便者，此是肾消病也。
特忌房劳。若消渴者倍黄连，消中者倍栝蒌，肾消者加芒硝六分，服前件铅丹丸。（《外台》）（按∶铅丹丸方未
见，疑是《千金》铅丹散为丸，然方中无黄连，存考。又此三证俱以一方治，知是皆下消之属。）
夫消渴者，日夜饮水百盏，尚恐不足，若饮酒则愈渴，三焦之疾。自风毒瓦斯酒色所伤于上焦，久则其病变为
小便频数，其色如浓油，上有浮膜，味甘甜如蜜，淹浸之久，诸虫聚食，是恶候也，此名消渴。中焦得此病，谓之
脾消，吃食倍常，往往加三两倍，只好饮冷，入口甚美，早夜小便频数，腰膝无力，小便如泔，日渐瘦弱，此名消
中也。下焦得此病，谓之肾消，肾宫日耗，饮水不多，吃食渐少，腰脚细瘦，遗沥散尽，手足久如竹形，其疾已牢
矣。愚医不识义理，呼为劳疾，或云下冷。如此不见痊期，疾久之，或变为水肿，或发背疮，或足膝发恶疮漏疮，
至死不救。（《卫生家宝》）
渴疾有三∶曰消渴，曰消中，曰消肾，分上中下焦而言之。夫三焦为无形之火热内烁，致精液枯乏，脏腑焦腐，饮
有形之水以浇沃，欲其润泽也。若热气上腾，心虚受之，火气散漫而不收敛（按∶《三因》曰∶消渴属心，故烦心，
致心火散蔓，渴而引饮。此黎氏所本），胸中烦躁，舌赤如血，唇红如坯，渴饮水浆，小便频数，名曰 渴，
属于上焦，病在标也。若热蓄于中，脾虚受之，伏阳蒸内，消谷喜饥，食饮倍常，不生肌肉，好饮冷水，小便频数，
色白如泔，味甜如蜜，名曰消中，又曰脾消，属于中焦，病在水谷之海也。若热伏于下焦，肾虚受之，致精髓枯竭，
引水自救而不能消，饮水一斗，小便反倍，味甘而气不臊，阴强而精自走，腿膝枯细，渐渐无力，名曰 肾，又曰
急，属于下焦，病在本也。无形之火热日炽，有形之水饮日加，五脏乃伤，气血俱败。水气内胜，溢于皮肤，则
传为跗肿；火热内胜，留于分肉之间，必为痈肿疮疡。此皆病之深而多致不疗，良可悯哉。（《简易》）
消渴轻也，消中甚焉，消肾又甚焉（按∶原举三证与黎氏同），若强中则其毙可立待也。虽然真水不充，日从
事于杯勺之水，其间小便或油腻，或赤黄，或泔白，或渴而且利，或渴而不利，或不渴而利，但所食之物，皆从
小便出焉。甚而水气浸渍，溢于肌肤，则胀为肿满；猛火自炎，留于分肉，则发为痈疽。此又病之深而证之变者
也。（《直指》）
消渴之疾，三焦受病也，有上消、中消、肾消。上消者，上焦受病，又谓之膈消病也，多饮水而少食，大便如
常，或小便清利，知其燥在上焦也，治宜流湿润燥。中消者，胃也，渴而饮食多，小便黄，经曰热能消谷，知热在中，
法云宜下之，至不欲饮食则愈。肾消者，病在下焦，初发为膏淋，下如膏油之状，至病成而面色黧黑，形瘦而耳焦，
小便浊而有脂，治法宜养血以整肃，分其清浊而自愈也。（《保
命集》）
复分为三消∶高消者，舌上赤裂，大渴引饮，《逆调论》云心移热于肺，传为膈消者是也，以白虎加人参汤治
之。中消者，善食而瘦，自汗，大便硬，小便数，叔和云口干饮水，多食善饥，虚瘅成消中者是也，以调胃承气、
三黄丸治之。下消者，烦躁引饮，耳叶焦干，小便如膏，叔和云焦烦水易亏，此肾消也，以六味地黄丸治之。《总
录》所谓未传能食者，必发脑疽背疮，不能食者，必得中满鼓胀，皆谓不治之证。洁古老人分而治之，能食而渴者，
白虎加人参汤，不能食而渴者，钱氏方白术散，倍加葛根治之。上中既平，不复传下消矣。前人用药，厥有旨哉。
（《东垣试效方》）
消渴有三等，肺消、脾消、肾消。肺消、肾消可治，惟有脾消不可治。肺消，热在上焦，可用凉药，如黄连等
皆可用，此疾多出于饮酒人，冬月盛寒，多以葱椒鸠鸽煮酒，或加食热面，遂得此疾，故可用凉药解之。如脾消则
饮食入腹，如汤浇雪，则随小便而出，落于混僻沟渠中，皆凝结如白脂，日可倍食数食，肌肤日益消瘦，用热药则
热愈甚，用凉药则愈见虚羸，故无治法。肾消者，渴而多饮水，小便白浊，肌肤虽日消瘦，然小便不如脾消之凝结坚
硬，饮食亦不倍多，此是肾虚弱，心气泮散所致，故可以补心肾，去烦热，则其疾可愈。（《活法秘方》）
中焦消渴，饮食入胃，传送太急，不生津液，食已则饥，胃中有热，宜用黄芩、石膏。（《丹溪纂要》）
三消，小便去多。上消消心，心火炎上，大渴而小便多。中消消脾，脾气热燥，饮食倍常，皆消为小便。下
消消肾，肾衰不能摄水，故小便虽多而渴。然小便既多，津液必
竭，久而未有不渴者，谓之全不渴，未有的论。（《要诀》）
上消者，经谓之膈消，膈消者，渴而多饮是也。中消者，经谓之消中，消中者，渴而饮食俱多，或不渴而独饮
是也。下消者，经谓之肾消（按∶经无此名，当作肺消），肾消者，饮一溲二，其溲如膏油，即膈消、消中之传
变，王注谓肺脏消燥，气无所持是也。盖肺藏气，肺无病则气能管摄津液，而津液之精微者，收养筋骨血脉，余者
为溲，肺病则津液无气管摄，而精微者亦随溲下，故饮一溲二而溲如膏油也。筋骨血脉无津液以养之，故其病成，
渐形瘦焦干也。然肺病本于肾虚，肾虚则心寡于畏，妄行凌肺而移寒与之，然后肺病消。故仲景治渴而小便反多，
用肾气丸补肾救肺，后人因名之肾消及下消也。（《纲目》）
消渴脚力盛衰时月 凡此疾与香港脚，虽同为肾虚所致，其香港脚始发于二三月，盛于五六月，衰于七八月，
凡消渴始发于七八月，盛于十一月十二月，衰于二月三月，其故何也？夫香港脚者，壅疾也，消渴者，宣疾也。春夏
阳气上，故壅疾发，即宣疾愈也；秋冬阳气下，故宣疾发，即壅疾愈也。审此二者，疾可理也。（《外台》引《近
效》祠部李郎中论）
重证 三消久而小便不臭，反作甜气，在溺桶中滚涌，其病为重。更有浮在溺面如猪脂，溅在桶边如 烛
泪，此精不禁，真元竭矣。（《要诀》）
病变痈疽 其病变多发痈疽，此坐热气留于经络不引（按∶此二字《外台》作经络不利），血气壅涩，
故成痈脓。（《病源论》）（按∶又渴病候曰∶或成水疾。）
消渴之人，愈与未愈，常须思虑有大痈。何者？消渴之人，必于大骨节间发痈疽而卒，所以戒之在大痈也，
当预备痈药以防之。（《千金》）
痈疽科谓有先渴而后疮者，先疮而后渴者，或有二证俱发，其危尤甚焉。愚且尝亲见有不幸而遭此者，故每
疗渴为之防疮，疗疮为之防渴，不过用八味丸、忍冬丸之类。（《澹寮》）（按∶忍冬丸系忍冬、甘草。）
夫消渴者，多变聋盲疮癣痤痱之类，皆肠胃燥热怫郁，水液不能浸润于周身故也。或热甚而膀胱怫郁，不能渗泄，
水液妄行而面上肿也。（《三消论》）
病变肿胀 脾土制水，通调水道，下输于膀胱。消渴饮水过度，内溃脾土，土不制水，故胃胀则为腹满之疾也。
Sanxiao (Three Wasting-Thirst Diseases) has, since ancient times, generally been discussed on the basis of Kidney Deficiency. Often, different names are established within the pattern of Kidney Deficiency, mostly because it spreads from Xiaxiao (Lower Wasting-Thirst). However, regarding the treatment of Shangxiao (Upper Wasting-Thirst) and Zhongxiao (Middle Wasting-Thirst), Liu Hejian and Li Dongyuan perhaps grasped the essence of the classics, although Shangxiao is quite rare. Now, collecting formulas and theories from various schools, they cannot be clearly distinguished; thus, they are tentatively combined into sections for scholars to examine and differentiate.
Etiology: Kidney Deficiency. Xiao (Wasting-Thirst) refers to thirst. When Qi of the Kidney does not circulate freely in the chest and stomach, the lack of fluid moistening leads to wasting-thirst, causing a desire to drink water. (*Shiming*)
Generally, many people live unrestrainedly. In their prime, failing to exercise caution and cherish their health, indulging in desires and sexual activity to excess, as they age, Kidney Qi becomes deficient and exhausted, giving rise to myriad diseases. Others, fearing impotence in youth, take mineral powders (such as Five-Stone Powder); once True Qi is depleted, the mineral Qi stands alone, resulting only in depletion. Symptoms include dry and cracked lips and mouth, spontaneous seminal emission, or red-yellow urine, dry and hard stools, or thirst with polyuria drinking one *shi* per day, or thirst without polyuria, or no thirst but polyuria, where all ingested food passes out as urine. All these result from unregulated sexual activity. (*Qianjin Fang*) [Note: Chao Yuanfang discusses wasting-thirst by dividing it into Xiao Ke, Ke Bing, Ke Li, and Neixiao. He attributes Ke Bing to heat generated by deficiency/excess in the Zang-Fu organs, leading to depleted fluids and thirst, without specifying the exact pattern. Others attribute it to heat accumulation in the Kidney from taking Five-Stone Powder. Since taking mineral powders is obsolete today, only the symptoms are excerpted below.]
Li Langzhong of the Shrine Department in *Jin Xiao Fang* states: The origin of wasting-thirst lies in Kidney Deficiency; upon onset, the urine becomes sweet. Physicians often do not understand this disease, so ancient texts omit it. Briefly stated: According to the *Hong Fan*, crops yield sweetness. Physically, syrups, vinegar, and wine can become sweet quickly, proving that food tastes sweet after ingestion. This flows to the Bladder. If Kidney Qi is strong, it steams Essence upward; Qi enters the Marrow, then forms fat, then blood and flesh; the remainder becomes urine. Thus, urine is yellow (excess of blood) and smells musky (Qi of the five Zang organs); salty and moist is the downward flavor. [Note: *Taiping Shenghui Fang* reads: "The upper remainder becomes tears/saliva... the lower remainder becomes urine..."] If the腰部 and Kidneys are deficient and cold, they cannot steam upward; grain Qi descends entirely as urine. Thus, the sweet taste remains unchanged, the color is clear and cold, and the skin and muscles wither. Like a nursing mother whose grain Qi transforms into milk, wasting-thirst patients excrete downward as urine; lacking internal Essence leads to emaciation. The Lung is the canopy of the five Zang organs; if there is warmth below, it steams and moistens the Lung. If the lower part is extremely cold, Yang Qi cannot ascend, causing Lung dryness and heat. The *I Ching* Hexagram Pi describes Heaven above and Earth below, where Yang blocks Yin from descending and Yin lacks Yang to ascend, causing obstruction. Like a pot of water heated by fire under a lid: steam rises and moistens the lid. Without fire, water vapor does not rise, and the lid remains dry. Fire represents strong腰部 and Kidneys, requiring warmth and care. Water vapor represents food Qi; with warmth, it moistens upward and aids digestion, preventing dryness. Therefore, Zhang Zhongjing said: It is suitable to take Ba Wei Shen Qi Wan (Eight-Ingredient Pill of the Kidney Qi), avoid cold foods and drinks, and thirst will cease. Having achieved frequent success, the correct formula is recorded below. (*Waitai Miyao*)
Wasting-thirst originates in the Kidney. In youth, failing to preserve health, indulging in sex and alcohol, eating dried meats and roasted foods, or taking cinnabar/minerals, causes Kidney Water to dry up, Heart Fire to blaze, Sanjiao to become fierce, and the five Zang organs to dry out, generating wasting-thirst. (*Jisheng Fang*)
Heaven generates Water, governed by the Kidney. The Bladder is the Fu organ of fluids, disseminating Kidney Water to moisten the Lung upwards. Thus, experts consider the Lung the organ of fluids; from top to bottom, the Sanjiao and Zang-Fu are contained within the True Water of Heaven. As *Suwen* states, the root of water is in the Kidney, and the branch in the Lung. If True Water is inexhaustible, what need is there for thirst? Only through licentiousness, unregulated alcohol, craving roasted/salty/sour/sweet/greasy foods, and using cinnabar/five stones to satisfy desires does flame scorch upwards, generating heat in the Zang-Fu, blazing dryness, drying fluids, and causing uncontrollable thirst. (*Zhizhi Fang*)
The Kidney governs Water. If True Water is inexhaustible, it nourishes the Spleen and communicates with the Heart, preventing dry wasting-thirst. But when Kidney Water is deficient, it fails to control residual Fire. Fire blazes, simmering the Zang-Fu; Fire intensifies due to Water's exhaustion, and Water dries due to Fire's intensity. Yang excess and Yin deficiency constitute this syndrome, making Sanxiao severe. Is not the root in the Kidney? (*Yu An*)
Etiology: Alcoholism. Long-term alcohol consumption invariably leads to wasting-thirst. Alcohol is extremely hot, hotter than any other substance. Dried meats and salt are staples for drinkers. After meals, self-control is lost; eating and drinking are excessive. Year after year, intoxication persists, causing fierce heat in Sanjiao and dryness in the five Zang organs. Wood and stone may scorch; how much more so humans? Cure depends on the patient. If regulated according to prescriptions, recovery occurs in weeks; if neglected, death follows swiftly. Many remedies exist, but what of those who are careless? (*Qianjin Fang*)
Pulse Diagnosis. In wasting-thirst, a rapid and large pulse indicates survival; a fine, small, floating, and short pulse indicates death. A deep and small pulse indicates survival; a solid, firm, and large pulse indicates death. (*Maijing*)
For Sanxiao, a floating and large pulse indicates survival; a fine, small, minute, and choppy pulse with physical collapse is alarming. (*Shanbu Siyan Juyao*)
In wasting patterns, a solid and large pulse matches the syndrome and is treatable even if chronic. A hanging, small, and firm pulse indicates the pulse does not match the disease and reveals the True Zang pulse, making treatment difficult. If the pulse is small but not hollow and firm, follow Zhang Zhongjing’s Zhengzhi with Shen Qi Wan. Historically, wasting-diabetes pulses always show rapidity; one must distinguish floating vs. deep rapidity, left vs. right, Chi vs. Cun excess/deficiency, and accompanying pulses for accurate treatment. Consider regional climate and constitutional strength to avoid treating deficiency as excess. (*Yitong*)
For Sanxiao with excessive dryness-heat, a solid, large, surging, and slippery pulse is treatable; a choppy and minute pulse indicates exhaustion of True Yin and is likely incurable. (*Yiji*)
Clinical Manifestations of Sanxiao. Xiao Ke is characterized by incessant thirst and polyuria. Ke Li is drinking followed immediately by urination. Neixiao is polyuria without thirst. (*Bingyuan Lun*) [Note: These refer to Xiaxiao; *Sanyin Fang* calls it Xiaoshen or Neixiao.]
A case of Ke Li starting in spring improved with Trichosanthes and Perilla juice over summer, yet urination remained frequent (20+ times/day, 2-3 sheng). Eventually stopped, but weight loss continued due to rich diet. Symptoms included dry throat/mouth, shortness of breath, irritability, heat, sore legs, and increased appetite without strength gain. This is caused by deficiency-heat. Treatment: Long-term Trichosanthes juice clears heat; cow’s milk and apricot cheese tonify. This method is beneficial. (*Qianjin Fang*) [Note: Matches Chao Yuanfang’s description of Xiaxiao.]
Neixiao arises from interior heat. Urine volume exceeds intake, causing extreme weakness and shortness of breath. Food digests directly into urine without thirst. Though rare, it is feared. Pulse is deep, fine, and weak; Gouqi Tang is effective. (*Same source*)
*Gujin Luyan* describes three types: 1. Thirst with heavy drinking and frequent sweet-smelling urine resembling bran flakes: Xiao Ke. 2. Heavy eating, slight thirst, infrequent oily urine: Xiaozhong. 3. Little drinking, leg swelling, thin feet, impotence, frequent urination: Xiaoshen. Avoid sexual exertion. For Xiao Ke, double Coptis; for Xiaozhong, double Trichosanthes; for Xiaoshen, add 6 fen Mangxiao. Take Qian Dan Wan. (*Waitai Miyao*) [Note: Formula missing; likely related to Qianjin Fang. Treated with one formula suggests all are Xiaxiao.]
Xiao Ke involves drinking hundreds of cups daily; alcohol worsens thirst. Caused by wind-toxin, qi, sex, and alcohol damaging the Upper Jiao. Long-term changes lead to frequent, dark-oily urine with a floating membrane, sweet as honey, attracting insects—a bad omen called Xiao Ke. Middle Jiao involvement is Pí Xiāo (Spleen Wasting): eating doubles, prefers cold drinks, frequent white turbid urine like rice wash, weak waist/knees, emaciation. Lower Jiao involvement is Shèn Xiāo (Kidney Wasting): Kidney palace depletes, little drinking/eating, thin waist/legs, dribbling urine, bamboo-like limbs, stubborn disease. Ignorant doctors call it劳疾 (Labor Disease) or lower cold. No cure; later complications include edema, back sores, or foul leg ulcers, leading to death. (*Weisheng Jiabao*)
Thirst diseases have three types based on Sanjiao: Invisible fire scorches fluids, drying Zang-Fu. Drinking water tries to moisten them.
1. Heat rises to the Heart (deficient), scattering Fire. Symptoms: irritability, red tongue/lips, thirst, frequent urination. Called Ge Ke (Diaphragm Thirst), Upper Jiao, manifest level.
2. Heat accumulates in the Middle, affecting the Spleen. Hidden Yang steams internally, digesting food quickly, hunger, double intake, no muscle gain, likes cold water, frequent white sweet urine. Called Xiaozhong or Pi Xiao, Middle Jiao, level of water/grain.
3. Heat hides in Lower Jiao, affecting the Kidney. Essence dries, drinking to save self but unable to absorb. Drink 1 dou, urinate 2 dou, sweet/non-musky urine, strong libido with sperm leakage, thin knees. Called Shen Xiao or Ji Lao, Lower Jiao, root level.
Invisible fire grows, visible water increases, injuring five Zang, ruining Qi/Blood. Water overflow causes edema; Fire retention causes abscesses. Deep diseases are hard to treat. (*Jianyi Fang*)
Xiao Ke is mild, Xiaozhong is severe, Xiaoshen is severest. Qiangzhong (Excessive Strength) leads to immediate death. True Water is insufficient; urine varies (oily, red, white). Food exits via urine. Severe cases: water overflow causes edema; fire causes carbuncles. (*Zhizhi Fang*)
Sanjiao is affected in wasting-thirst: Shangxiao, Zhongxiao, Xiaoxiao.
Shangxiao (Upper Jiao/Ge Xiao): Drinks much, eats little, normal stool/clear urine. Dryness in Upper Jiao. Treat with moistening.
Zhongxiao (Stomach): Thirsty, eats much, yellow urine. Heat in Middle. Treat with purgatives until appetite returns.
Xiaoxiao (Lower Jiao/Kidney): Starts as Gaolin (paste-like urine), turns black face, thin body, burnt ears, turbid fatty urine. Treat with blood-nourishing and separating clear/turbid. (*Baoming Ji*)
Re-divided into three:
Gao Xiao (High Thirst): Red cracked tongue, great thirst. Heart heat transfers to Lung (Ge Xiao). Treat with Baihu Jia Renshen Tang.
Zhong Xiao: Eats well but loses weight, sweating, hard stool, frequent urine. Stomach heat. Treat with Tiaowei Chengqi Tang or Sanhuang Wan.
Xia Xiao: Irritable, thirsty, burnt ear lobes, paste-like urine. Kidney deficiency. Treat with Liuwei Dihuang Wan.
If able to eat, brain/back sores develop; if unable to eat, abdominal distension develops—both untreatable. Jiegu treats separately: Eating/thirsty -> Baihu Jia Renshen Tang; Not eating/thirsty -> Qian’s Baizhu San plus Ge Gen. Once Upper/Middle settle, it won’t transmit to Lower. Precious wisdom. (*Dongyuan Shi Xiao Fang*)
Three grades: Fei Xiao, Pi Xiao, Shen Xiao. Fei and Shen are treatable; Pi is not.
Fei Xiao: Heat in Upper Jiao. Use cooling herbs like Huanglian. Common in drinkers consuming spicy/pigeon wine or hot noodles in winter. Cooling herbs resolve it.
Pi Xiao: Food melts like snow in urine, congeals like white fat. Eats multiples, wastes away. Hot herbs increase heat; cold herbs increase deficiency. No treatment.
Shen Xiao: Thirsty, drinks much, white turbid urine, wastes away but urine doesn’t congeal, eats normally. Kidney deficiency, Heart Qi scattered. Tonify Heart/Kidney, clear heat. (*Huofa Mifang*)
Middle Jiao Wasting-Thirst: Food transmits too fast, no fluids produced, hungry after eating. Stomach heat. Use Huangqin, Shigao. (*Danxi Zuanya*)
Sanxiao involves excessive urine loss.
Shangxiao affects Heart: Heart Fire flares, great thirst, polyuria.
Zhongxiao affects Spleen: Spleen heat/dryness, double intake, all converts to urine.
Xiaxiao affects Kidney: Kidney failure to control water, polyuria despite thirst.
Long-term polyuria exhausts fluids, inevitably causing thirst. Total absence of thirst is debated. (*Yaojue*)
Shangxiao is Ge Xiao (thirst + drinking). Zhongxiao is Xiaozhong (thirst + eating/drinking). Xiaxiao is Shen Xiao (drink 1, urinate 2, paste-like urine). Wang Bing notes Lung dryness lacks Qi support. Lung stores Qi; healthy Lung controls fluids. Fine fluids nourish sinews/bones/vessels; remainder becomes urine. Lung disease loses control, fine fluids drain with urine. Sinews/bones lack nourishment, leading to emaciation. Lung disease stems from Kidney Deficiency; Kidney deficiency allows Heart Fire to insult Lung. Zhang Zhongjing uses Shen Qi Wan to tonify Kidney/save Lung. Hence named Xiaxiao. (*Bencao Gangmu*)
Seasonality of Leg Strength in Wasting-Thirst vs. Jiaogong (Foot Distemper). Both stem from Kidney Deficiency. Jiaogong starts Feb-Mar, peaks May-Jun, subsides Jul-Aug. Wasting-Thirst starts Jul-Aug, peaks Nov-Dec, subsides Feb-Mar. Why? Jiaogong is an obstructive disease; Wasting-Thirst is a dispersing disease. Spring/Summer Yang rises: Obstructive disease flares, Dispersing heals. Autumn/Winter Yang sinks: Dispersing flares, Obstructive heals. Understanding this manages the disease. (*Waitai Miyao* citing *Jin Xiao*)
Severe Cases. Long-term Sanxiao urine loses odor, smells sweet, bubbles in chamber. Floating fat like lard on surface or candle wax on sides indicates Essence leakage and exhaustion of True Yuan. (*Yaojue*)
Complications: Carbuncles/Abscesses. Heat stays in meridians, blocking Qi/Blood stasis, forming pus. (*Bingyuan Lun*) [Note: Also mentions water diseases.]
Patients recovering or not must guard against major carbuncles. Death often occurs from carbuncles at major joints. Prepare carbuncle medicines. (*Qianjin Fang*)
Carbuncle specialists note: Thirst before sore, sore before thirst, or both together are critical. I have seen this. Treating thirst requires guarding against sores, and vice versa, using Bawei Wan or Rendong Wan. (*Danliao Fang*) [Note: Rendong Wan contains Honeysuckle and Licorice.]
Wasting-thirst often complicates into deafness, blindness, sores, tinea, acne, prickly heat. Intestines/Stomach dryness-heat stagnates, preventing fluid distribution. Or bladder heat stagnation prevents excretion, causing facial edema. (*Sanxiao Lun*)
Complications: Edema/Swelling. Spleen Earth controls Water, regulating channels to Bladder. Excessive drinking in wasting-thirst damages Spleen Earth. Earth fails to control Water, causing stomach distension and abdominal fullness.
