（以下俱杂病，于五脏无所敷，故列于后）
〔娄〕治小儿疟疾，多与大人同法，以出汗为瘥，宜桂枝、柴胡、麻黄、参、苓
等辈，又视其病食、病痰，以意消息之，大抵多是饮食失节得之，须以消导为先可
也。〔曾〕《内经》疟论∶ 疟皆生于风，而发作有时何也？岐伯曰∶夏伤于暑，秋
必病疟。谓腠理开而汗出遇风，或得于澡浴，水气舍于皮肤，因卫气不守，邪气并
居。其疾始作，伸欠寒栗，腰背俱痛，骨节烦疼，寒去则内外皆热，头疼而渴，乃
阴阳二气交争，虚实更作而然。阴气独盛则阳虚，故先寒战栗，腰背头项骨节皆痛，
阳气独胜则阴虚，故先热，发时不嗜食，善呕，头疼腰痛，小便不利，阴盛阳虚则
内外皆寒，阳盛阴虚则内外俱热，此外感六淫或内伤七情，蕴积痰饮，病气与卫气并
居，故病日作，卫气昼行于阳，夜行于阴，得阳而外出，得阴而内薄，内薄五脏，病
气深入，不能与卫气俱出，则间日而作。当卫气所至，病气所在，则发在阳则热，
在阴则寒。经曰∶亢则害，极乃反，俟阴阳各衰，卫气与病气相杂则病休，阴阳相
搏，卫气与病气再集则病复，各随其卫气之所在，与所中邪气相合而然也。先寒后
热者，先伤寒而后伤风，名曰寒疟。先热后寒者，先伤风而后伤寒，名曰温疟。但
热不寒者，名曰瘅疟。身重寒热，骨节痛，腹胀满，自汗善呕，名曰湿疟。但寒不
热者，名曰牝疟。盖疟之为病，为证非一，故处方之制，随其阴阳虚实，脉病证治，
汗吐下温，对证施治，以平为期。然百病中人，必因其正气之虚，感受邪气，留而
不去，其病为实，自表传里，先汗后下，古今不易，故治疟之法，必须先表，用百
解散（惊）水姜葱煎投，次小柴胡汤（往来寒热）加桂、水姜枣煎服，以和解表里之邪，自然作
效。若表里实，用当归散（潮热）、五和汤（里热）或乌犀丸（积）、六圣丸（积）下之，匀气散（疝）止
补，后以藿香饮（不乳食）加草果、良姜、水姜枣煎投，正胃气，去寒邪，则自平复。如
解表后寒热往来，以二仙饮（本条）截之，寒热既除，用平胃散（不乳食）加茴香汤（腹痛）和匀，
盐汤空心调服，温胃燥脾，进美饮食，使中州之土既实，则外邪不战而自屈，此为
明论。有寒多热少，经久不愈，致脾胃弱，饮食减，神色变，二姜丸（本条）及清脾汤
（本条）为治。〔薛〕经曰∶夏伤于暑，秋必 疟。其证先起于毫毛伸欠，乃作寒栗鼓颔，
腰脊俱痛，寒去则内外皆热，头痛如破，渴欲冷冻饮料，盖邪气并于阳则阳胜，并于阴
则阴胜，阴胜则寒，阳胜则热，阴阳上下交争，虚实更作，故寒热间发也。有一日
一发，二日一发，三日一发，有间一日连二日发，有日与夜各发，有上半日发，下
半日发，及发于夜者，有有汗，有无汗，此其略也。以详言之，当分六经五脏及痰、
食、劳、暑、鬼瘴之不同（六经五脏疟详见杂病准绳）。痰疟者，胸膈先有停痰，因而成疟，
令人心下胀满，气逆烦呕是也。食疟者，是饮食伤脾，其人噫气吞酸，胸膈不和是
也。劳疟者，久而不瘥，表里俱虚，客邪未散，真气不复，故疾虽间，遇劳即发是
也。暑疟者，其人面垢口渴，虽热已退，亦常有汗是也。鬼疟者，进退无时是也。
瘴疟者，感山岚瘴气，其状寒热休作有时是也。久而不愈，名曰 疟， 疟、老疟
也，老疟不愈，结癖于两胁之间，名曰疟母，此先失于解散，或复外感风寒，内伤
饮食，故缠绵不已也。治法，风暑之邪从外而入，宜解散之，解表后，即宜扶持胃
气，故丹溪曰∶无汗要有汗，散邪为主，有汗要无汗，固正气为主，骤发之疟宜解
表，久发之疟宜补脾，寒疟宜温，温疟宜和，瘅疟宜清，挟痰则行痰，兼食则消食，
劳疟宜安，暑疟宜解，鬼疟宜祛，瘴疟宜散，此亦其略也。更以详言之，则热多寒
少者小柴胡汤。寒多热少者清脾饮子。无汗者桂枝麻黄各半汤。有汗者柴胡桂枝汤。
汗多渴者白虎汤。渴而小便不利者五苓散。小便赤，热多而渴者，小柴胡汤。热多
汗出，腹满便 者，大柴胡汤，渴加葛根。痰疟者，二陈汤（痰涎）加柴胡、黄芩，甚者
加枳实。食疟者，先用大安丸（宿食），次用异功散（吐泻）。劳疟、 疟，并用补中益气汤
（虚热）。暑疟者，十味香薷饮。鬼疟者，鬼哭散。瘴疟者，四兽饮。疟母者，鳖甲饮。
凡脾胃虚而患疟者，不拘有汗无汗，三阴六经，悉以六君子汤为主，热多加柴胡、
山栀，寒多加干姜、肉桂，有汗加黄 、浮麦，无汗加苍术、葛根，元气下陷，及
肝木乘脾，并加升麻、柴胡、为善。若用青皮、草果、常山等药，以为攻截良法，
正气益虚，邪气益深，是多延绵不止，而为劳热者有矣。若乳母七情六欲，饮食不
调，或寒热似疟，肝火炽盛，致儿为患者，又当治其乳母，斯无误矣。
《全生指迷》论曰∶寒热之病，或寒已而热，或热已而寒。若寒热战栗，头痛如
破，身体拘急，数欠，渴欲饮冷，或先寒而后热，或先热而后寒，或 时而发，或
间日而作，至其时便发，发已如常，此谓之疟。疟脉自弦，弦数多热，弦迟多寒，
此皆得之于冬中风寒之气，藏于骨髓之中，至春阳气大发，邪气不能自出，因遇大
暑，而后与邪气相合而发，寒多者宜温之与姜桂汤，热多者宜解之与栝蒌汤，寒热
等者宜调之与鳖甲汤。大人小儿疟疾，若寒从背起，冷大如手，不甚战栗，似欲
发热而汗出，或即头痛，呕吐时作，其脉迟小，此由脾胃素弱，因气寒而收聚水谷，
不能克化，变而成痰，伏痰在内，阴上乘阳，阳为阴所乘，所以作寒，逼而成汗，
宜服旋复花丸、半硫丸。
（以下均为杂病，与五脏没有直接的敷布关系，所以列在后面）
〔娄〕治疗小儿疟疾，大多与成人治疗方法相同，以出汗作为痊愈的标志，适宜使用桂枝、柴胡、麻黄、人参、茯苓等药物，另外还要根据是否有饮食积滞或痰饮致病的情况，酌情斟酌处理，大体上多是因饮食不节制而得病，必须以消食导滞为先，这样就可以了。〔曾〕《内经·疟论》说：疟疾都生于风邪，但为什么发作有定时呢？岐伯回答说：夏季感受暑邪，秋季必定患疟疾。这是因为腠理开泄而汗出时遇到风邪，或者洗澡时水气停留在皮肤之间，因为卫气不能固守，邪气与之并居。疾病刚开始发作时，伸欠哈欠、恶寒战栗，腰背都疼痛，骨节烦痛，寒气退去后内外都发热，头痛且口渴，这是阴阳二气相互交争，虚实交替变化所致。阴气单独偏盛则阳气虚弱，所以先出现寒战、腰背头项及骨节疼痛；阳气单独偏盛则阴虚，所以先发热，发病时不想吃东西，容易呕吐，头痛腰痛，小便不利。阴盛阳虚则内外皆寒，阳盛阴虚则内外俱热。这是外感六淫邪气或内伤七情，蕴积痰饮，病气与卫气并居，所以疾病每天发作。卫气白天行于阳分，夜晚行于阴分，遇到阳分则外出，遇到阴分则内迫，内迫五脏，病气深入，不能随卫气一起外出，就会隔日发作。当卫气到达病气所在之处，病气在阳分就发热，在阴分就发冷。经书说：亢盛就会造成危害，极盛就会反过来，等到阴阳之气各自衰减，卫气与病气混杂则疾病休止，阴阳相互搏结，卫气与病气再次聚集则疾病复发，这都是随着卫气所在的位置，与所中的邪气相合而形成的。先冷后热的，是先受寒邪而后受风邪，名叫寒疟。先热后冷的，是先受风邪而后受寒邪，名叫温疟。只有热没有冷的，名叫瘅疟。身体沉重、忽冷忽热、骨节疼痛、腹部胀满、自汗且容易呕吐的，名叫湿疟。只有冷没有热的，名叫牝疟。大概疟疾这种病，证候不止一种，所以处方的制定，要随着其阴阳虚实、脉象病症的治疗原则，采用汗、吐、下、温等方法，对证施治，以达到平衡为准则。然而各种疾病侵入人体，必然是因为正气虚弱，感受邪气，停留不去，病势转为实证，由表传里，先用汗法后用下法，古今不变。所以治疗疟疾的方法，必须先解表，用百解散（主治惊风）用水、生姜、葱白煎服，接着用小柴胡汤（主治往来寒热）加桂枝、生姜、大枣煎服，以和解表里的邪气，自然见效。如果表里俱实，用当归散（主治潮热）、五和汤（主治里热）或乌犀丸（主治积滞）、六圣丸（主治积滞）攻下，用匀气散（主治疝气）止泻补虚，随后用藿香饮（主治不吃奶/饭）加草果、良姜、生姜、大枣煎服，调理胃气，去除寒邪，则自然平复。如果在解表后仍有寒热往来，用二仙饮（见本条）截断疟疾，寒热既除，用平胃散（主治不吃奶/饭）加茴香汤（主治腹痛）调和均匀，空腹时用盐汤调服，温胃燥脾，增进饮食，使中焦脾胃之气充实，则外邪不战而自屈，这是明理之论。如果有寒多热少，经久不愈，导致脾胃虚弱，饮食减少，神色改变，可用二姜丸（见本条）及清脾汤（见本条）治疗。〔薛〕经书说：夏季感受暑邪，秋季必患疟疾。其症状先从毫毛竖起、伸欠开始，接着出现寒战鼓颔（牙齿打颤），腰脊都疼痛，寒气退去后内外都发热，头痛如裂，想喝冷冻饮料，这是因为邪气并入阳分则阳胜，并入阴分则阴胜，阴胜则寒，阳胜则热，阴阳上下交争，虚实交替，所以寒热间隔发作。有一日一发，两日一发，三日一发，有隔一天连两天发作的，有白天黑夜各发作一次的，有上半日发作，下半日发作，以及夜间发作的，有有汗的，有无汗的，这些是大略情况。详细来说，应当分为六经五脏及痰、食、劳、暑、鬼瘴等不同类型（六经五脏疟详见《杂病准绳》）。痰疟，是胸膈原本有停痰，因而形成疟疾，让人心下胀满，气逆烦闷呕吐。食疟，是饮食损伤脾胃，其人嗳气吞酸，胸膈不和。劳疟，是日久不愈，表里俱虚，客邪未散，真气不复，所以疾病虽然间歇，但遇劳累即发作。暑疟，其人面色垢浊口渴，即使热退，也常有汗出。鬼疟，是发作时间进退无常。瘴疟，是感受山岚瘴气，其状寒热休作有时。日久不愈，名叫久疟，也就是老疟。老疟不愈，结癖在两胁之间，名叫疟母，这先是失于解散，或是又外感风寒，内伤饮食，所以缠绵不已。治疗方法，风暑之邪从外而入，宜解散之，解表后，即应扶持胃气，所以丹溪说：无汗要有汗，以散邪为主；有汗要无汗，以固正气为主。骤发的疟疾宜解表，久发的疟疾宜补脾，寒疟宜温，温疟宜和，瘅疟宜清，挟痰则行痰，兼食则消食，劳疟宜安，暑疟宜解，鬼疟宜祛，瘴疟宜散，这也是大略情况。更详细地说，热多寒少的用小柴胡汤。寒多热少的用清脾饮子。无汗的用桂枝麻黄各半汤。有汗的用柴胡桂枝汤。汗多口渴的用白虎汤。口渴且小便不利的用五苓散。小便赤，热多而口渴的，用小柴胡汤。热多汗出，腹部胀满大便溏泄的，用大柴胡汤，口渴加葛根。痰疟的，用二陈汤（主治痰涎）加柴胡、黄芩，严重的加枳实。食疟的，先用大安丸（主治宿食），次用异功散（主治吐泻）。劳疟、久疟，并用补中益气汤（主治虚热）。暑疟的，用十味香薷饮。鬼疟的，用鬼哭散。瘴疟的，用四兽饮。疟母的，用鳖甲饮。凡是脾胃虚弱而患疟疾的，不管有汗无汗，三阴六经，都以六君子汤为主方，热多加柴胡、山栀，寒多加干姜、肉桂，有汗加黄芪、浮小麦，无汗加苍术、葛根，元气下陷，及肝木乘脾，并加升麻、柴胡，才算妥善。如果用青皮、草果、常山等药，以为攻截的好方法，会导致正气更虚，邪气更深，多是拖延不止，而成为劳热的就有这种情况了。如果是乳母七情六欲失调，饮食不调，或寒热似疟，肝火炽盛，致使婴儿患病，又应当治疗乳母，这样才不会出错。
《全生指迷》论述说：寒热病，有的寒已而热，有的热已而寒。如果寒战栗，头痛如裂，身体拘急，频繁哈欠，想喝冷水，或先冷后热，或先热后冷，或定时发作，或隔日发作，到了时候便发作，发作完像常人一样，这叫疟疾。疟疾的脉象自弦，弦数脉多热，弦迟脉多寒，这些都是冬天感受风寒之气，藏在骨髓之中，到春天阳气大发，邪气不能自行排出，因为遇到大暑，而后与邪气相合而发作，寒多的宜温之与姜桂汤，热多的宜解之与栝蒌汤，寒热相等的宜调之与鳖甲汤。大人小儿疟疾，如果寒从背部起，冷感大如手掌，不太战栗，似乎要发热而出汗，或者随即头痛，呕吐时常发生，其脉迟小，这是由脾胃素来虚弱，因气寒而收聚水谷，不能消化，变而成痰，伏痰在内，阴上乘阳，阳被阴所乘，所以作寒，逼而成汗，宜服用旋复花丸、半硫丸。
(Below are miscellaneous diseases, which do not have a direct distribution relationship with the five Zang organs, so they are listed afterwards.)
[Lou] The treatment of malaria in children is mostly the same as that for adults, with sweating being the sign of recovery. It is appropriate to use herbs such as Guizhi (Cinnamon Twig), Chaihu (Bupleurum Root), Mahuang (Ephedra Herb), Renshen (Ginseng Root), and Fuling (Poria) etc. Additionally, one must consider whether the disease is caused by food stagnation or phlegm-fluid retention, and adjust the treatment accordingly. Generally, it is mostly due to irregular diet, so resolving food stagnation and promoting digestion should be prioritized. [Zeng] The *Neijing: Malaria Chapter* states: "Malaria arises from wind pathogens, but why does it occur at specific times?" Qibo replied: "Summer injury by heat leads to autumn malaria." This means that when pores are open and sweat is discharged, wind is encountered, or water vapor stays on the skin after bathing, because Wei Qi (Defensive Qi) fails to guard, and pathogenic factors reside together. When the disease first starts, there are yawning, aversion to cold, and shivering, pain in the waist and back, and vexing pain in bone joints. After the cold subsides, both interior and exterior become hot, accompanied by headache and thirst. This is due to the contention between Yin and Yang Qi, resulting from alternating deficiency and excess. If Yin Qi alone is excessive, Yang Qi becomes deficient, hence chills, pain in the waist, back, head, neck, and joints appear first. If Yang Qi alone is excessive, Yin becomes deficient, hence fever appears first; during onset, there is loss of appetite, frequent vomiting, headache, lower back pain, and difficult urination. Yin excess and Yang deficiency lead to coldness inside and out; Yang excess and Yin deficiency lead to heat inside and out. This is caused by external contraction of the Six Excesses or internal injury of the Seven Emotions, accumulating phlegm-fluids, where pathogenic Qi resides with Wei Qi, causing daily attacks. Wei Qi travels through Yang during the day and Yin at night; encountering Yang, it moves outward; encountering Yin, it presses inward. Pressing into the Five Zang organs, the pathogenic Qi goes deep and cannot exit with Wei Qi, leading to every-other-day attacks. When Wei Qi reaches the location of the pathogenic Qi, if it is in Yang, there is heat; if in Yin, there is cold. The classics say: "Exuberance causes harm, extremity reverses." When Yin and Yang Qi decline, and Wei Qi mixes with pathogenic Qi, the disease rests. When Yin and Yang contend, and Wei Qi gathers again with pathogenic Qi, the disease recurs. This happens according to the location of Wei Qi combining with the invaded pathogen. Cold first then heat indicates cold pathogen first then wind pathogen, named Cold Malaria. Heat first then cold indicates wind pathogen first then cold pathogen, named Warm Malaria. Only heat without cold is named Dan Malaria (Febrile Malaria). Heavy body, alternating cold and heat, joint pain, abdominal fullness, spontaneous sweating, and easy vomiting is named Damp Malaria. Only cold without heat is named Pin Malaria. Since malaria presents various syndromes, prescriptions vary according to Yin-Yang deficiency/excess, pulse, symptoms, and treatment principles, using sweating, vomiting, purging, or warming methods to treat the syndrome, aiming for balance. However, all diseases invade the body due to righteous Qi deficiency, allowing pathogenic Qi to linger and transform into excess, transmitting from exterior to interior, using sweating first then purging, an unchanging principle since ancient times. Thus, treating malaria must start with releasing the exterior, using Baijie San (for fright) decocted with water, fresh ginger, and scallion, followed by Xiaochaihu Tang (for alternating cold and heat) added with Guizhi, fresh ginger, and jujube, decocted and taken to harmonize and resolve exterior-interior pathogens, naturally achieving effect. If exterior and interior are both excess, use Danggui San (for tidal fever), Wuhe Tang (for interior heat), or Wuxi Wan (for accumulation), Liusheng Wan (for accumulation) to purge, Yongqi San (for hernia) to stop diarrhea and tonify, then Huoxiang Yin (for poor feeding) added with Caoguo (Black Cardamom), Liangjiang (Galangal), fresh ginger, and jujube, decocted and taken to regulate Stomach Qi and remove cold pathogens, leading to natural recovery. If alternating cold and heat persists after releasing the exterior, use Erxian Yin (see this section) to intercept the malaria. Once cold and heat are removed, use Pingwei San (for poor feeding) added with Huixiang Tang (for abdominal pain), mixed evenly, and taken empty-stomach with salt water to warm the stomach, dry the spleen, improve appetite, and strengthen the Middle Jiao Earth, so external pathogens retreat without battle, which is a clear theory. For cases with more cold than heat, persisting for a long time, leading to weak Spleen-Stomach, reduced diet, and changed complexion, use Erjiang Wan (see this section) and Qingpi Tang (see this section). [Xue] The classics say: "Summer injury by heat leads to autumn malaria." Symptoms begin with hair standing up and yawning, followed by chills and teeth chattering, pain in the waist and spine. After cold subsides, interior and exterior become hot, headache like splitting, desire for cold drinks. This is because pathogenic Qi merging with Yang makes Yang excessive, merging with Yin makes Yin excessive; Yin excess causes cold, Yang excess causes heat. Upper and lower Yin-Yang contend, deficiency and excess alternate, hence intermittent cold and heat. There are cases of once a day, once every two days, once every three days, skipping one day then two days, occurring day and night, morning or afternoon, or at night, with or without sweating, these are generalities. Detailed analysis divides them into Six Channels, Five Zang organs, and differences due to phlegm, food, labor, summer-heat, ghost, and miasma types (Six Channel and Five Zang malaria detailed in *Miscellaneous Diseases Standard*). Phlegm Malaria: Phlegm stops in chest and diaphragm, forming malaria, causing subcostal fullness, rebellious Qi, vexation, and vomiting. Food Malaria: Diet injures Spleen, causing belching, acid regurgitation, and chest-diaphragm discomfort. Labor Malaria: Long duration without recovery, exterior and interior both deficient, guest pathogen not scattered, true Qi not restored, so although intermittent, it triggers upon exertion. Summer-heat Malaria: Face is greasy, thirsty, even after fever subsides, sweating often occurs. Ghost Malaria: Onset and cessation are unpredictable. Miasma Malaria: Contracted mountain miasma, presenting with intermittent cold and heat. Prolonged non-recovery is called Chronic Malaria or Old Malaria. If Old Malaria does not heal, a mass forms between the hypochondrium, called Malaria Mother (Maiku), due to initial failure to release the exterior, or subsequent external cold-wind invasion and internal dietary injury, causing lingering persistence. Treatment: Wind-summer-heat pathogens enter from outside, suitable for resolution. After releasing the exterior, support Stomach Qi immediately. Thus, Danxi said: "No sweat needs sweat, primarily dispersing pathogen; Sweat needs no sweat, primarily consolidating righteous Qi." Acute malaria suits exterior release; chronic malaria suits Spleen tonification. Cold malaria suits warming; Warm malaria suits harmonizing; Dan malaria suits clearing; with phlegm resolves phlegm; with food resolves food; Labor malaria suits calming; Summer-heat malaria suits resolving; Ghost malaria suits expelling; Miasma malaria suits dispersing. These are generalities. More specifically: More heat less cold uses Xiaochaihu Tang. More cold less heat uses Qingpi Yin. No sweat uses Guizhi Mahuang Ban Tang. Sweating uses Chaihu Guizhi Tang. Profuse sweating and thirst uses Baihu Tang. Thirst with difficult urination uses Wuling San. Red urine, more heat and thirst uses Xiaochaihu Tang. More heat, sweating, abdominal fullness, and loose stools uses Dachaihu Tang, add Gegen (Kudzu Root) if thirsty. Phlegm Malaria uses Erchen Tang (for phlegm-sputum) added with Chaihu and Huangqin (Scutellaria Root), severe cases add Zhishi (Immature Bitter Orange). Food Malaria first uses Da'an Wan (for retained food), then Yigong San (for vomiting/diarrhea). Labor Malaria and Chronic Malaria both use Buzhong Yiqi Tang (for deficient heat). Summer-heat Malaria uses Shiwei Xiangru Yin. Ghost Malaria uses Guiku San. Miasma Malaria uses Sishe Yin. Malaria Mother uses Biejia Yin. For those with weak Spleen-Stomach suffering malaria, regardless of sweating or not, across Three Yin and Six Channels, Liu Junzi Tang is the main formula. Add Chaihu and Zhizi (Gardenia Fruit) for more heat; Ganjiang (Dried Ginger) and Rougui (Cinnamon Bark) for more cold; Huangqi (Astragalus Root) and Fumai (Floating Wheat) for sweating; Cangzhu (Atractylodes Rhizome) and Gegen for no sweat. For sinking of Yuan Qi and Liver Wood overacting on Spleen, add Shengma (Cimicifuga Rhizome) and Chaihu, which is optimal. Using Qingpi (Tangerine Peel), Caoguo, Changshan (Polygala Root) etc., thinking them good interception methods, will further deplete righteous Qi and deepen pathogen, often leading to prolonged persistence and becoming deficient heat. If the nursing mother has emotional/desire imbalance, improper diet, or alternating cold-heat resembling malaria with blazing Liver Fire, causing illness in the infant, one must treat the nursing mother to avoid error.
*Quansheng Zhimi* discusses: Cold-heat diseases, some have heat after cold, some cold after heat. If chills, headache like splitting, body stiffness, frequent yawning, desire for cold drinks, or cold then heat, or heat then cold, or regular onset, or every-other-day onset, occurring exactly at the time, returning to normal after attack, this is called Malaria. Malaria pulse is naturally wiry; wiry-numerous indicates more heat; wiry-slow indicates more cold. All arise from winter wind-cold qi stored in bone marrow. In spring, Yang Qi expands greatly, pathogen cannot exit spontaneously. Encountering great summer heat, it combines with pathogen to erupt. More cold suits warming with Jianggui Tang. More heat suits resolving with Gualou Tang. Equal cold-heat suits regulating with Biejia Tang. For adult and child malaria, if cold starts from back, feeling cold like a hand's size, little shivering, seeming to want to sweat, or sudden headache, occasional vomiting, pulse slow and small, this is due to inherent weak Spleen-Stomach, cold Qi gathering grain/water, unable to digest, transforming into phlegm. Hidden phlegm inside, Yin rises over Yang, Yang oppressed by Yin causes cold, forced sweating ensues. Suitable for Xuanfuhua Wan and Banshu Wan.
