脉象：六部脉搏隐伏不见。右关脉呈弦滑之象。若见浮洪脉，尚可治疗；若脉微而迟，气息微弱且不愿说话，则难以治疗。两关脉弦缓者，属于木克土（肝木克制脾土）的病理机制，若不紧急治疗，将会导致死亡。
症状：陈无择说：霍乱病，表现为心腹突然疼痛，呕吐并伴有腹泻，怕冷且高热，头痛眩晕。如果先感到心痛，就会先发生呕吐；如果先感到腹痛，就会先发生痢疾（此处指剧烈腹泻）；如果心腹都痛，则呕吐和腹泻同时发作。严重时，筋脉抽搐牵引至腹部，随即死亡。这种病症是由于阴阳之气逆乱，清浊之气相互干扰，阳气突然上升，阴气骤然断绝所致。治疗应当适宜温补温暖，切忌使用寒凉药物。筋脉抽搐是因为阳明经滋养宗筋，归属于胃与大肠。如今突然剧烈呕吐和腹泻，津液瞬间亡失，加上外感风、寒、暑、湿四气，内伤喜、怒、忧、思、悲、恐、惊七情，以及饮食甜腻之物，攻闭了各种经脉，导致宗筋枯瘦削弱，失去滋养必然导致挛缩。严重时出现舌头卷曲、睾丸上缩的情况，属于难治之症。又有干霍乱这一类型，忽然感到心腹胀满，绞痛如刺，心中烦闷冤屈，想吐吐不出，想拉拉不出，片刻之间就会导致窒息昏厥，最难治疗，往往顷刻间死亡。这是因为气机升降不通的缘故。只有催吐法最为良效，或者采用泻下法也很巧妙。在催吐或泻下之后，用二陈汤（燥湿化痰、理气和中的方剂）加入人参、白术来调理身体。
治疗：霍乱病，属于阳明病证，宜以调和脾胃、平胃为主。使用生姜理中汤治疗效果最好。若出现呕吐腹泻、筋脉抽搐、胁下疼痛、脉弦者，属于木克土，使用平胃散（燥湿运脾、行气和胃的方剂），加入木瓜主治。若出现呕吐腹泻、筋脉抽搐、腹中疼痛、身体沉重、脉沉细者，使用四君子汤（益气健脾的方剂）加入白芍药、干姜主治。若四肢厥冷、脉微者，使用附子理中汤（温阳祛寒、益气健脾的方剂）主治。若身体发热、烦躁口渴者，使用钱氏白术散主治。对于筋脉抽搐者，男子可用手牵拉其阴囊，女子可用手牵拉其乳房，这是《千金方》中的妙法。大抵来说，此症发病急骤时无药可施，唯有陈氏的催吐法最佳，随后根据症状进行调理。
方剂：六和汤用于治疗伏暑引起的霍乱。
药材：人参、白术、半夏、杏仁（各八分）、甘草（四分）、砂仁（六分）、藿香、木瓜、茯苓、扁豆、浓朴（各一钱）、香茹（一钱五分）。
用法：以上药材作为一服，使用生姜三片、大枣一枚，加水一钟半，煎煮至八分，不拘时间服用。
加减法：
如果不口渴、腹痛、呕吐腹泻，加入干姜（七分）。
如果口渴、腹痛、呕吐腹泻，加入干葛（八分）、泽泻、滑石（各七分）、麦门冬（八分）、五味子（五分）。
如果出现筋脉抽搐，加入酒当归、酒红花（各七分）、黄芩（八分）。
如果四肢厥冷、脉微者，加入干姜、附子（各一钱）。
又一方：三因吐法用于治疗霍乱及干霍乱，特别是在急需用药却无药可用的情况下，此法极为巧妙。使用极咸的盐汤二升，热饮一升，刺激口腔探喉令其吐出宿食直至排尽，若不吐则继续服用，吐完后仍继续服用，经过三次催吐后停止。此法远胜于其他方法。世俗之人轻视而不使用，只能坐视病人死亡，令人悲哀啊。催吐之后，使用二陈汤加入人参、白术进行调理，万无一失。
Pulse: The pulses in all six positions are hidden and imperceptible. The pulse at the right Guan position is wiry and slippery. If a floating and surging pulse is observed, the condition is treatable; if the pulse is faint and slow, accompanied by weak breath and reluctance to speak, it is difficult to treat. A wiry and moderate pulse at both Guan positions indicates Wood overacting on Earth (Liver Wood suppressing Spleen Earth). Without urgent treatment, death will ensue.
Symptoms: Chen Wuyue stated: Huoluan (cholera-like syndrome) is characterized by sudden pain in the heart and abdomen, vomiting with diarrhea, aversion to cold with high fever, headache, and dizziness. If heart pain occurs first, vomiting precedes; if abdominal pain occurs first, diarrhea precedes; if both heart and abdomen hurt, vomiting and diarrhea occur simultaneously. In severe cases, muscle cramps may pull into the abdomen, leading to sudden death. This syndrome arises from the reversal of Yin and Yang Qi, where clear and turbid Qi interfere with each other, Yang Qi rises suddenly, and Yin Qi abruptly ceases. Treatment should favor warming and tonifying, strictly avoiding cooling agents. Muscle cramps occur because the Yangming channel nourishes the Zongjin (major sinews), which belong to the Stomach and Large Intestine. Now, due to sudden violent vomiting and diarrhea, body fluids are instantly lost. Combined with external contraction of the Four Qi (Wind, Cold, Summerheat, Dampness), internal injury from the Seven Emotions, and consumption of sweet and greasy foods, various meridians are blocked, causing the Zongjin to wither and lose nourishment, inevitably resulting in spasms. In severe cases, tongue retraction and testicular retraction occur, which are difficult to treat. There is also a type called Gan Huoluan (Dry Cholera), characterized by sudden abdominal distension and fullness, twisting stabbing pain, mental distress, inability to vomit or defecate, leading to suffocation and coma within moments. It is the most difficult to treat, often causing death in an instant due to the obstruction of ascending and descending mechanisms. Only emesis (inducing vomiting) is the best method, or purgation can also be effective. After emesis or purgation, Erchen Tang (Two-Aged Decoction) combined with Renshen (Ginseng) and Baizhu (Atractylodes Macrocephala Rhizome) should be used for regulation.
Treatment: Huoluan belongs to the Yangming syndrome category. Treatment should focus on harmonizing the middle and regulating the stomach. Shengjiang Lizhong Tang (Fresh Ginger Regulate the Middle Decoction) is most effective. For cases with vomiting, diarrhea, muscle cramps, hypochondriac pain, and a wiry pulse, indicating Wood overacting on Earth, Pingwei San (Regulate the Stomach Powder) with Mugua (Chaenomelis Fructus) is indicated. For cases with vomiting, diarrhea, muscle cramps, abdominal pain, heavy body sensation, and a deep, fine pulse, Sijunzi Tang (Four Gentlemen Decoction) with Baishao (White Peony Root) and Ganjiang (Dried Ginger) is indicated. For cases with cold limbs and a faint pulse, Fuzi Lizhong Tang (Aconite Regulate the Middle Decoction) is indicated. For cases with body heat, irritability, and thirst, Qianshi Baizhu San (Qian's Atractylodes Powder) is indicated. For muscle cramps, men should have their scrotum gently pulled by hand, and women should have their breasts gently pulled by hand; this is a wonderful method from Qianjin Fang. Generally, when this syndrome strikes urgently without available medicine, Chen's emesis method is best, followed by symptom-based regulation.
Formula: Liuhe Tang (Six Harmonies Decoction) treats Huoluan caused by latent summerheat.
Ingredients: Renshen (Ginseng Radix et Rhizoma), Baizhu (Atractylodis Macrocephalae Rhizoma), Banxia (Pinelliae Tuber), Xingren (Armeniacae Semen Amarum) (each 8 fen), Gancao (Licorice Radix et Rhizoma) (4 fen), Sharen (Amomi Fructus) (6 fen), Huoxiang (Agastaches Herba), Mugua (Chaenomelis Fructus), Fuling (Poria), Bian Dou (Vigna Seed), Houpo (Magnoliae Officinalis Cortex) (each 1 qian), Xiangru (Elsholtziae Herba) (1.5 qian).
Preparation: Combine as one dose. Add three slices of fresh ginger and one jujube. Add 1.5 zhong of water, decoct until 0.8 zhong remains. Take at any time.
Modifications:
If not thirsty, with abdominal pain, vomiting, and diarrhea, add Ganjiang (Dried Ginger) (7 fen).
If thirsty, with abdominal pain, vomiting, and diarrhea, add Ge Gen (Puerariae Lobatae Radix) (8 fen), Zexie (Alismatis Rhizoma), Huashi (Talcum) (each 7 fen), Maidong (Ophiopogonis Radix) (8 fen), Wuweizi (Schisandrae Fructus) (5 fen).
For muscle cramps, add Jiudanggui (Wine-processed Angelica Sinensis Radix), Jiu Honghua (Carthami Flos) (each 7 fen), Huangqin (Scutellariae Radix) (8 fen).
For cold limbs and faint pulse, add Ganjiang (Dried Ginger) and Fuzi (Aconiti Lateralis Radix Praeparata) (each 1 qian).
Another Formula: Sanyin Tu Fa (Three Causes Emesis Method) treats Huoluan and Gan Huoluan, especially when urgent medication is unavailable. This method is extremely effective. Use highly saline salt water (2 sheng), drink 1 sheng hot, stimulate the throat to induce vomiting until old food residue is expelled. If vomiting does not occur, administer again. Continue after vomiting stops, repeating three times then cease. This method far surpasses others. Secular practitioners despise and do not use it, sitting idly while patients die, which is lamentable. After emesis, regulate with Erchen Tang (Two-Aged Decoction) plus Renshen (Ginseng Radix et Rhizoma) and Baizhu (Atractylodis Macrocephalae Rhizoma); this ensures success without failure.
