仲景问曰。病有霍乱者何。答曰。呕吐而利。此名霍乱。
问曰。病发热头痛。身疼恶寒。吐利者。此属何病。答曰。此名霍
乱。吐利而复发热也。（一作自吐下又利止复更发热）雍曰。此论霍
乱似伤寒之症也。
又曰。伤寒。其脉微涩者。本是霍乱。今是伤寒。却四五日。至阴
经上转入阴。必利。（一作吐利）本呕。下利者。不可治也。欲似大便。
而反失气。仍不利者。此属阳明也。便必硬。十三日愈。所以然者。经
尽故也。下利后。当便硬。硬则能食者愈。今反不能食。到后经中。颇
能食。复过一经。能食。过之一日。当愈。不愈者。不属阳明也。恶寒。
脉微而（一作缓）复利。利止亡血也。四逆加人参汤主之。雍曰。此论
今是伤寒之症。故言本呕下利不可治。若论霍乱。则必呕吐而利也。
一是伤寒而不属阳明。恶寒脉微复利。利止者。则用四逆加人参汤
主之。此汤若霍乱症亦可服。千金翼合二论为一。是当经有缺文。
问曰。霍乱何由而致也。雍曰。胸中逆乱之气也。初无疾而霍
乱。往往饮食失节。而致胸中逆乱也。故伤寒而霍乱者。阴阳二气乱
于胸中也。灵枢三十四篇曰。清气在阴。浊气在阳。营气顺脉。卫气
逆行。清浊相干。乱于胸中。是为大 。
又曰。乱于肠胃。则为霍乱。
经言五乱。霍乱其一也。惟乱于胸。所以吐。乱于肠。所以利也。孙真
人曰。饮食 狯。复食乳酪。海陆百品。无所不啖。眠卧冷席。多饮寒
浆。胃中诸食。结而不消。阴阳二气壅而伏痰。阳气欲升。阴气欲降。
阴阳乖隔。变成吐利。头疼如破。百节如解。遍体诸筋。皆为回转。论
时虽小。卒病之中。最为可畏。虽临履薄危。不足论也。故古人语此
者。刺之则徐出徐入。导气而已。非补泻也。用药者。顺其阴阳之气
而已。无汗下也。此伏治乱气之道。

又曰。吐利发汗。脉平。小烦者。以新虚不胜谷气故也。雍曰。勿服药。损谷则愈。
叔和曰。转筋为病。其人臂脚直。脉上下行。微弦。转筋入腹。鸡屎白散主之。
千金要方曰。凡霍乱。务在温和将息。若冷则遍体转筋。凡此
病。定一日不食为佳。仍须三日少少饮粥。三日以后。可恣意食息。七日勿杂食为佳。所以养脾气也。
又曰。凡诸霍乱。忌与米饮。胃中得米即吐不止。但与浓朴葛

又曰。霍乱吐多者。必转筋不渴。即脐上筑。霍乱而脐上筑者。
为肾气动。当先治其筑。治中汤主之。去术加桂心。去术者。以肾虚
故也。加桂者。恐作奔豚也。霍乱而脐上筑吐多者。若下多者。霍乱
而惊悸。霍乱而渴。霍乱而腹中痛。呕而吐利。呕而利。欲得水者。皆用治中汤主之。

肢逆冷。汗自出。两脚转筋。宜服香薷散。须井中沉令极冷。顿服之。
乃效。雍曰。香薷、浓朴、 豆。皆古人治霍乱要药。故此药为有理。
中暑霍乱。惟纳冷水饮则不复吐逆。时有以新汲水服理中丸。亦佳。灵苑方煮良姜末。沉令极冷服。皆宜冷服。
问曰。传信载柳州尝得干霍乱。吐之愈。诸家未见有言干霍乱
者。有之乎。雍曰。有之。第当时不能究其说。真言少伪耳。近世之
人。尤不知也。霍乱者。五乱之一也。皆作吐利。无干而不吐利者。其
不吐利者。乱气也。按灵枢经五乱之症。惟乱于肠胃一症名霍乱。故
作吐利。其余四症。皆不作吐利。只谓之乱气。柳州之疾。盖乱气干
心之症。非霍乱也。谓为干霍乱者虽谬。然尚不失为五乱之一。今则
无复知乱气之名矣。
张仲景问道：“什么是霍乱病？”回答说：“呕吐且腹泻，这就叫霍乱。”
又问：“如果病人出现发热、头痛、身体疼痛、恶寒，同时伴有呕吐和腹泻，这属于什么病？”回答说：“这也叫霍乱。即先有呕吐腹泻，随后又出现发热。”（另一种说法是：原本自行呕吐或腹泻，后来停止，之后又重新发热。）郭雍说：“这段论述中提到的霍乱症状，类似于伤寒的症状。”
又说：“患伤寒病，脉象微而涩的，原本是霍乱病，现在转为伤寒。过了四五天，邪气传入阴经，必定会出现腹泻。（另一种说法是呕吐和腹泻）原本有呕吐，若出现腹泻，则难以治愈。病人想大便，却反而排气，仍不排便的，这属于阳明病。大便必定干硬，十三天会痊愈。之所以这样，是因为经络之气运行完毕的缘故。腹泻停止后，大便应当变硬，大便变硬如果能进食，说明病愈。现在反而不能进食，等到下一个经气循环周期时，稍微能进食了，再经过一个经气循环周期，若能正常进食，过了一天就会痊愈；如果不愈，则不属于阳明病。如果恶寒，脉象微细而又腹泻，腹泻停止是由于亡血（津液枯竭）所致。应用四逆加人参汤主治。”郭雍说：“这段论述的是当前为伤寒的症状，所以说‘原本呕吐腹泻’的情况难以治愈。如果是论及霍乱，则必然表现为呕吐和腹泻。一种是伤寒而不属于阳明病，表现为恶寒、脉微细且腹泻，腹泻停止的，就用四逆加人参汤主治。这个方剂对于霍乱症状也可以服用。《千金翼方》将这两段论述合为一处，说明原经文可能有缺漏。”
又问：“霍乱是如何引起的？”郭雍说：“是胸中逆乱之气造成的。起初没有疾病，往往因为饮食不节制，导致胸中气机逆乱。所以患伤寒并引发霍乱的，是阴阳二气在胸中混乱。《灵枢经·五乱第三十四篇》说：‘清气在下，浊气在上，营气顺经脉运行，卫气逆行，清浊之气相互干扰，扰乱于胸中，这就称为大乱。’又说：‘扰乱于肠胃，就形成霍乱。’经文所说的‘五乱’，霍乱是其中之一。只有气乱于胸，所以发生呕吐；气乱于肠，所以发生腹泻。孙思邈说：‘饮食无度，又食用乳酪，海陆各种食物无所不食，睡冷席，多喝冷饮，胃中的食物凝结不消化，阴阳二气壅滞伏留成痰，阳气欲升，阴气欲降，阴阳乖隔，变成呕吐腹泻。头痛如裂，全身关节像要散开一样，遍体筋脉都发生扭转。虽然这种病发作时间短，但在急症之中，最为可怕。即使面临生死危险，也不足为奇。所以古人治疗这种情况，针刺时要缓慢出针、缓慢进针，只是引导气机而已，并非补泻手法。用药者，只需顺应其阴阳之气即可，不需要发汗或攻下。这是平息紊乱之气的道理。’”
张仲景说：“霍乱，头痛、发热、身体疼痛，热多，想喝水的，用五苓散主治。寒多，不想喝水的，用理中丸主治。”
又说：“呕吐腹泻停止但身体疼痛不止的，应当斟酌情况调和表邪，适宜用小剂量桂枝汤和解。”
又说：“呕吐腹泻伴出汗，发热恶寒，四肢拘挛紧急，手足冰冷的，用四逆汤主治。”
又说：“既呕吐又腹泻，小便通畅且大汗出，下利排出未消化的食物，内寒外热，脉象微弱几乎摸不到的，用四逆汤主治。”
又说：“呕吐腹泻已停止，但出汗且手足厥冷，四肢拘挛紧急不能缓解，脉象微弱几乎摸不到的，用通脉四逆加猪胆汁汤主治。《千金翼方》说：若无猪胆，可用羊胆代替。《千金方》另有加减法。”
又说：“霍乱呕吐腹泻后发汗，脉象平和，仅有轻微心烦的，是因为新近虚弱，不胜受纳谷气所致。郭雍说：不要服药，减少饮食摄入就会痊愈。”
王叔和说：“转筋作为病症，患者手臂和腿脚僵硬伸直，脉象上下直行，微带弦象。转筋牵引至腹部，用鸡屎白散主治。”
《千金要方》说：“凡是霍乱，务必注意温和调养。如果受冷，会导致遍体转筋。凡此病，最好第一天禁食，仍需三天少量喝粥，三天以后，可以随意饮食休息，七天之内不吃杂食为佳，以此来养护脾气。”
又说：“凡是各种霍乱，忌讳饮用米汤。胃中得到米就会呕吐不止。只给浓朴葛根饮，或者冬瓜叶饮，只要沾润咽喉即可，不可多给。如果服药时随吐而出，等呕吐停止后再止服。诊察脉搏绝不通畅，用桂枝合葛根煮水饮用。呕吐腹泻后心烦，内热，不出汗，不转筋，脉象急数的，可用犀角合葛根煮水饮用。呕吐腹泻不止，发汗后心烦，想喝水的，可少量饮用米粉汁为佳。如果仍不止，可给葛根荠菜饮服用。”
又说：“霍乱呕吐多的，必然转筋且不口渴，此时感觉脐上跳动不安。霍乱且脐上跳动的，是肾气动，应当先治疗脐上跳动，用治中汤主治。去掉白术，加入桂心。去掉白术，是因为肾虚的缘故；加入桂心，是担心发展为奔豚病。霍乱且脐上跳动、呕吐多的，如果腹泻多的，霍乱且惊悸的，霍乱且口渴的，霍乱且腹中痛的，呕吐且腹泻的，呕吐且腹泻且想喝水的，都用治中汤主治。”
又说：“治中汤治疗霍乱呕吐腹泻，腹胀满，食物不消化，心腹痛。”
又说：“霍乱多寒证，手足冰冷，脉象绝迹的，适宜用当归四逆加吴茱萸汤。旧方用大枣三十枚，如今根据霍乱病多痞塞的特点，故去除大枣。如去掉大枣，加入葛根二两较好。霍乱，四逆汤加半夏一合，小附子一枚。恶寒严重的，用大附子。（朱氏医书没有这些加减法，故详细记录）”
又说：“霍乱呕吐腹泻后，服用理中汤、四逆汤、四顺汤热象仍未解除的，用竹叶汤主治。（与竹叶石膏汤方不同）”
又说：“毒冷霍乱，呕吐腹泻烦躁呕吐，转筋，肌肉冷汗出，手指脚趾皆肿，喘息垂死，声音不出，百方无效，脉象不通的，服用人参汤，取效为止。随吐随服，不要停止。并配合艾灸。”
又说：“老人身体瘦弱，冷气恶心，饮食不化，心腹虚胀满闷，拘急短气，霍乱呕逆，四肢冰冷，心烦气闷，流汗，用扶老理中汤。原系理中散，常服用时用蜜制成丸药。”
又说：“霍乱四肢逆冷，呕吐少而呕吐多的，用附子粳米汤主治。”
又说：“妇人霍乱，呕逆，吐涎沫，医生反而用攻下法，导致心下痞塞，应当先治疗吐涎沫，可服用小青龙汤。涎沫停止后，再治疗痞塞，可与甘草泻心汤。”
又说：“中热霍乱，剧烈腹泻心烦，脉数，想要喝冷水的，用新汲取的井水顿服一升。”
又说：“凡是霍乱，艾灸或许不能立即痊愈，但最终不会有死亡忧虑。不可逆向艾灸。或者只是先腹泻后呕吐，应当根据病情症状进行艾灸。郭雍说：治疗霍乱的方法，以《千金要方》最为详备。除了前面收录的内容外，还有霍乱余症及转筋危症等十六种方法，灸法十八种，应当参考一同使用。”
《活人书》说：“夏季中暑引发的霍乱，上吐下利，心腹撮痛，大渴烦躁，四肢逆冷，汗自出，两脚转筋，适宜服用香薷散。必须放入井水中沉至极冷，顿服才有效。郭雍说：香薷、厚朴、扁豆，都是古人治疗霍乱的要药，所以此药很有道理。中暑霍乱，只有喝冷水则不再呕吐逆气。有时用新汲水送服理中丸，也很好。《灵苑方》煮良姜末，沉至极冷服用，都适宜冷服。”
又问：“《传信方》记载柳宗元曾患干霍乱，通过催吐治愈。各家未见有提及干霍乱的，有吗？”郭雍说：“有的，只是当时没能探究其原理。真言少伪罢了。近代的人尤其不知道。霍乱，是五乱之一，都表现为呕吐腹泻，没有干而不吐利的。那些不吐利的，称为乱气。按《灵枢经》五乱的病症，只有‘乱于肠胃’这一症名为霍乱，所以表现为吐利。其余四症，都不表现为吐利，只称为乱气。柳宗元的病，大概是乱气干犯心脏的病症，不是霍乱。称之为干霍乱虽然错误，但尚不失为五乱之一。如今已经没有知道‘乱气’这一名称的人了。”
Zhang Zhongjing asked, "What is Huoluan (cholera-like disease)?" The answer was, "Vomiting and diarrhea; this is named Huoluan."
Another question was raised: "If a patient presents with fever, headache, body ache, aversion to cold, along with vomiting and diarrhea, what disease does this belong to?" The answer was, "This is also named Huoluan. Specifically, vomiting and diarrhea followed by the reappearance of fever." (An alternative version states: originally spontaneous vomiting or diarrhea, which then ceased, followed by recurrent fever.) Guo Yong commented, "The symptoms of Huoluan described here resemble those of Shanghan (Cold Damage)."
It is further stated: "In cases of Shanghan, if the pulse is faint and choppy, it was originally Huoluan but has now transformed into Shanghan. After four or five days, when the pathogen enters the Yin meridians, diarrhea will certainly occur." (Alternative version: vomiting and diarrhea). "If there was originally vomiting and now diarrhea appears, it is difficult to treat. If the patient feels the urge to defecate but instead passes flatus and does not stool, this belongs to Yangming disease. The stool will likely be hard. Recovery will occur on the thirteenth day. This is because the meridian cycle has completed its course. After diarrhea stops, the stool should become hard; if the patient can eat when the stool is hard, recovery ensues. If the patient cannot eat now, but slightly regains appetite during the next meridian cycle, and normal eating resumes after one more cycle, recovery should occur one day later. If not, it does not belong to Yangming. If there is aversion to cold, a faint pulse, and recurring diarrhea, and the diarrhea stops due to depletion of blood/fluids, Si Ni Jia Ren Shen Tang (Four Counterflow Decoction plus Ginseng) should be administered." Guo Yong commented, "This passage discusses symptoms where Shanghan is currently present, hence stating that 'original vomiting and diarrhea' are difficult to treat. If discussing Huoluan itself, it must involve both vomiting and diarrhea. One scenario is Shanghan not belonging to Yangming, presenting with aversion to cold, faint pulse, and diarrhea; if diarrhea stops, Si Ni Jia Ren Shen Tang is indicated. This decoction can also be used for Huoluan symptoms. Qianjin Yi Fang combined these two discussions, suggesting missing text in the original scripture."
Another question asks: "How is Huoluan caused?" Guo Yong answered, "It is caused by rebellious Qi in the chest. Initially without disease, improper diet often leads to rebellious Qi in the chest. Thus, in Shanghan complicated by Huoluan, the Yin and Yang Qi are chaotic in the chest. Ling Shu, Chapter 34, states: 'Clear Qi descends while turbid Qi ascends; Ying Qi flows smoothly with the vessels, while Wei Qi moves in reverse. Clear and turbid Qi interfere with each other, causing great chaos in the chest.' It further says, 'Chaos in the intestines and stomach results in Huoluan.' The scripture mentions 'Five Chaos,' of which Huoluan is one. Chaos in the chest causes vomiting; chaos in the intestines causes diarrhea. Sun Simiao said: 'Indulgence in food and drink, consumption of dairy and rich foods from land and sea, sleeping on cold mats, and drinking excessive cold fluids cause food stagnation in the stomach. Yin and Yang Qi become obstructed and generate phlegm. Yang Qi desires to ascend, Yin Qi desires to descend; their separation leads to vomiting and diarrhea. Headache feels like splitting, joints feel as if dislocating, and tendons throughout the body twist. Although the illness is acute, among sudden diseases, it is most terrifying. Even facing life-threatening danger, it is not surprising. Therefore, ancients treated this by slow insertion and withdrawal of needles, merely guiding Qi, not using tonification or sedation. Medicinal treatment involves harmonizing Yin and Yang Qi, without inducing sweating or purging. This is the method to quell chaotic Qi.'"
Zhang Zhongjing stated: "For Huoluan with headache, fever, body pain, predominant heat, and thirst, Wu Ling San (Five-Ingredient Powder with Poria) is indicated. For predominant cold and no thirst, Li Zhong Wan (Regulate the Middle Pill) is indicated."
It is also stated: "If vomiting and diarrhea cease but body pain persists, one should assess the exterior and harmonize it; Gui Zhi Tang (Cinnamon Twig Decoction) in a small dose is appropriate."
It is also stated: "For Huoluan with vomiting and diarrhea, sweating, fever, aversion to cold, tetany of the limbs, and cold extremities, Si Ni Tang (Four Counterflow Decoction) is indicated."
It is also stated: "For simultaneous vomiting and diarrhea, free urination, profuse sweating, diarrhea with undigested food, internal cold with external heat, and a faint pulse nearly imperceptible, Si Ni Tang (Four Counterflow Decoction) is indicated."
It is also stated: "After vomiting and diarrhea have stopped, if sweating and cold extremities persist, limb tetany remains unresolved, and the pulse is faint and nearly imperceptible, Tong Mai Si Ni Tang Jia Zhu Dan Ye (Pulse-Unblocking Four Counterflow Decoction plus Pig Bile Juice) is indicated. Qianjin Yi Fang notes: if pig bile is unavailable, sheep bile may substitute. Qian Jin Fang provides additional modification methods."
It is also stated: "After Huoluan vomiting and diarrhea, if sweating occurs and the pulse becomes calm, with only slight restlessness, this is due to recent deficiency failing to handle grain Qi. Guo Yong comments: Do not administer medicine; reducing food intake will lead to recovery."
Wang Shuhe stated: "For tetany, the arms and legs are stiff and straight, the pulse runs vertically up and down with a slight wiry quality. If tetany extends to the abdomen, Ji Shi Bai San (Chicken Dropping White Powder) is indicated."
Qian Jin Yao Fang states: "For all Huoluan, gentle care and warming are essential. Cold exposure causes generalized tetany. Ideally, fast for the first day. For three days, consume small amounts of rice gruel. After three days, resume normal diet. Avoid mixed foods for seven days to nourish Spleen Qi."
It is also stated: "For all types of Huoluan, avoid rice water. Rice in the stomach induces continuous vomiting. Instead, provide Hou Po Ge Gen Yin (Magnolia Bark and Kudzu Root Drink) or Dong Gua Ye Yin (Winter Melon Leaf Drink), moistening the throat only, not giving large quantities. If vomiting occurs upon ingestion, stop until vomiting ceases. If the pulse is absent, use Gui Zhi He Ge Gen Yin (Cinnamon Twig and Kudzu Root Drink). For post-vomiting/diarrhea restlessness, internal heat, anhidrosis, no tetany, and rapid/tight pulse, Xi Jiao He Ge Gen Yin (Rhinoceros Horn and Kudzu Root Drink) is suitable. For persistent vomiting/diarrhea, sweating-induced restlessness, and thirst, small amounts of rice flour juice are best. If ineffective, Ge Gen Qi Yin (Kudzu and Shepherd's Purse Drink) may be given."
It is also stated: "Huoluan with predominant vomiting causes tetany and lack of thirst, accompanied by palpitations above the navel. Huoluan with palpitations above the navel indicates Kidney Qi movement; treat the palpitations first with Zhi Zhong Tang (Regulate the Middle Decoction). Remove Bai Zhu (Atractylodes Macrocephala Rhizome) and add Gui Xin (Cinnamon Bark). Bai Zhu is removed due to Kidney deficiency; Gui Xin is added to prevent Ben Tun (Running Piglet) syndrome. For Huoluan with abdominal palpitations and heavy vomiting, or heavy diarrhea, or palpitations, or thirst, or abdominal pain, or vomiting with diarrhea, or vomiting/diarrhea with thirst, Zhi Zhong Tang is universally indicated."
It is also stated: "Zhi Zhong Tang treats Huoluan vomiting and diarrhea, distension, indigestion, and heart/abdominal pain."
It is also stated: "For Huoluan with tetany, cold sweat, vomiting, and hiccups, Si Shun Tang (Four Smooth Decoction) is indicated."
It is also stated: "For Huoluan with predominant cold, cold extremities, and absent pulse, Dang Gui Si Ni Jia Wu Zhu Yu Tang (Angelica Sinensis Four Counterflow Decoction plus Evodia Fruit) is appropriate. Old formulas use thirty dates; however, since Huoluan often involves obstruction, dates are omitted. Replacing dates with Er Liang Ge Gen (two taels of Kudzu Root) is better. For Huoluan, Si Ni Tang adds Ban Xia (Pinellia Tuber) one he and one small Fu Zi (Aconite Lateral Root). For severe aversion to cold, use a large Fu Zi. (Zhu's medical book lacks these modifications, so they are recorded in detail.)"
It is also stated: "If Huoluan vomiting and diarrhea persist despite administering Li Zhong Tang, Si Ni Tang, or Si Shun Tang, Zhu Ye Tang (Bamboo Leaf Decoction) is indicated. (Note: This differs from Zhu Ye Shi Gao Tang)."
It is also stated: "For toxic-cold Huoluan with vomiting, diarrhea, restlessness, vomiting, tetany, cold sweat, swelling of fingers and toes, dyspnea nearing death, aphonia, inefficacy of hundred remedies, and blocked pulse, Ren Shen Tang (Ginseng Decoction) should be taken until recovery. Administer continuously even if vomiting occurs. Combine with moxibustion."
It is also stated: "For frail elderly patients with cold Qi, nausea, indigestion, empty fullness in heart and abdomen, tetany, shortness of breath, Huoluan with vomiting/reversal, cold extremities, restlessness, stifling sensation, and sweating, Fu Lao Li Zhong Tang (Supporting the Aged Regulate-the-Middle Decoction) is used. Originally Li Zhong San, taken regularly as honey pills."
It is also stated: "For Huoluan with cold extremities, less vomiting but more retching, Fu Zi Jing Mi Tang (Aconite and Rice Decoction) is indicated."
It is also stated: "For women with Huoluan, vomiting/reversal, and spitting saliva/phlegm, if physicians mistakenly use purgatives, epigastric oppression results. Treat the spitting/phlegm first with Xiao Qing Long Tang (Minor Green Dragon Decoction). Once phlegm stops, treat the oppression with Gan Cao Xie Xin Tang (Licorice Drain-the-Epigastrium Decoction)."
It is also stated: "For heat-stroke Huoluan with violent diarrhea, restlessness, rapid pulse, and desire for cold water, drink one sheng of fresh well-water at once."
It is also stated: "For all Huoluan, moxibustion may not cure immediately but prevents death. Do not apply moxa inversely. If diarrhea precedes vomiting, moxa according to symptoms. Guo Yong comments: Treatment methods for Huoluan are most comprehensive in Qian Jin Yao Fang. Besides previously recorded items, there are sixteen methods for residual Huoluan symptoms and critical tetany, and eighteen moxibustion methods, which should be consulted and used together."
Huo Ren Shu states: "For summerheat-induced Huoluan with vomiting, diarrhea, cramping abdominal pain, extreme thirst, restlessness, cold extremities, spontaneous sweating, and leg tetany, Xiang Ru San (Mosla Powder) is suitable. It must be chilled in well water and taken at once to be effective. Guo Yong comments: Xiang Ru (Mosla Chinensis Herb), Hou Po (Magnolia Bark), and Dou (likely Bian Dou or similar) are key herbs for Huoluan, making this prescription logical. For summerheat Huoluan, drinking cold water stops vomiting. Sometimes Li Zhong Wan taken with fresh well-water is also good. Ling Yuan Fang suggests boiling Liang Jiang (Galangal) powder, chilling it, and taking it cold; all should be taken cold."
A question asks: "Chuan Xin Fang records that Liu Zongyuan suffered from Gan Huoluan (Dry Cholera) and was cured by emesis. No other schools mention Gan Huoluan. Does it exist?" Guo Yong answered, "It exists, though its mechanism was not fully explored then. Truth contains little falsehood. Modern people especially do not understand it. Huoluan is one of the Five Chaos, always presenting with vomiting and diarrhea; there is no 'dry' form without vomiting/diarrhea. Those without vomiting/diarrhea are termed 'Luan Qi' (Chaotic Qi). According to Ling Shu, only 'chaos in intestines/stomach' is named Huoluan, thus causing vomiting/diarrhea. The other four chaos types do not cause vomiting/diarrhea and are called Chaotic Qi. Liu Zongyuan's condition was likely Chaotic Qi invading the Heart, not Huoluan. Calling it Gan Huoluan is erroneous, yet it remains one of the Five Chaos. Today, the name 'Chaotic Qi' is forgotten."
