体内有积滞，外部受邪气侵袭，出现严重的呕吐和腹泻，若症状未完全缓解，仍需使用催吐法，以提举上逆之气。催吐可用二陈汤（燥湿化痰、理气和中的方剂）加减，或者用盐汤、盐水均可起到催吐作用。
治疗霍乱：苍术、厚朴、陈皮、葛根（以上各一钱半），滑石（三钱），白术（二钱），木通（一钱），炙甘草。另一种方法是用姜汤送服保和丸四十粒。
治疗干霍乱（指欲吐不得吐、欲泻不得泻的危重证候）的大法，发汗或催吐都可以，这是因为内有饮食损伤，外被邪气郁遏所致；采用催吐法，兼具发散邪气的意义；采用温药解散者，其法也是解散邪气，不使用寒凉药物。可在二陈汤基础上加入川芎、苍术、防风、白芷等药物。
夏季霍乱伴有呕吐腹泻，患者极度想喝水，或神志狂乱奔走，可用姜制厚朴、官桂（肉桂）、干姜、茯苓、半夏。
治疗霍乱的方剂：藿香、苍术、厚朴、陈皮、缩砂仁、白芷、甘草、半夏、茯苓、人参、炒神曲，以上药物等分。遇寒邪加重加干姜，寒邪极重加附子。
对于呕吐腹泻型的霍乱，夏季可用冰水调服益元散（滑石、甘草、朱砂组成的方剂），并加入姜汁服用。也可用地浆水（挖地三尺所得之土加水搅拌沉淀后的清水）或清水调服桂苓甘露饮（化气利湿、清热解暑的方剂），新汲取的井水也可以，因为至阴之物能滋生阳中之阴。
霍乱伴有轻微烦躁口渴，可用钱氏白术散，上述两个方剂均记载于《卫生宝鉴》中。夏季呕吐腹泻，可用黄连香薷汤，在井水中浸冷后服用。
霍乱的脉象多表现为伏脉或绝脉，大法宜用理中汤（温中祛寒、补气健脾的方剂）。阳气不升、阴气不降，阻隔中焦而成霍乱，切不可给予米汤饮用，否则会导致死亡。
夏季因多食瓜果、冷饮，且乘风受凉，导致食物停滞不化，因食积形成痞块，隔绝上下气机，从而形成霍乱，可用六和汤（调和脾胃、行气化湿的方剂）并倍量使用藿香。
挥霍撩乱而既不能吐也不能泻，称为干霍乱。干霍乱最难治疗，必须用盐汤催吐。
治疗搅肠沙（一种剧烈腹痛、欲吐泻不得的病证），用樟木屑煎煮浓汤，喝下一碗，片刻后即可引发呕吐和腹泻。（另一种说法认为干霍乱俗称搅肠沙。）
另一种方法，在委中穴处若有紫暗色络脉，刺破出血即可缓解；或者在十个手指尖放血，也是良法。
When there is accumulation internally and pathogenic factors externally, resulting in severe vomiting and diarrhea, if the symptoms are not completely resolved, emesis should still be induced to raise the stagnant Qi. Emesis can be achieved using Er Chen Tang (Two-Cured Decoction) with modifications, or simply by drinking salt water or saline solution.
Treatment for Huoluan (Cholera-like syndrome): Cangzhu (Atractylodis Rhizoma), Houpo (Magnoliae Officinalis Cortex), Chenpi (Citri Reticulatae Pericarpium), Gegen (Puerariae Lobatae Radix) (each 1.5 qian); Huashi (Talcum) (3 qian); Baizhu (Atractylodis Macrocephalae Rhizoma) (2 qian); Mutong (Akebiae Caulis) (1 qian); Zhigancao (Prepared Glycyrrhizae Radix et Rhizoma). Another method involves administering Baohe Wan (Preserve Harmony Pill) forty pills with ginger decoction.
The general principle for treating Gan Huoluan (Dry Cholera, characterized by inability to vomit or defecate) allows for diaphoresis (sweating-inducing therapy) or emesis, as this condition arises from internal injury (dietary) and external constraint by pathogenic factors. Using emesis incorporates the meaning of dispersing pathogens; using warm herbs to resolve the condition also aims at dispersion, avoiding cold/cooling herbs. Modifications to Er Chen Tang may include Chuanxiong (Ligustici Chuanxiong Rhizoma), Cangzhu, Fangfeng (Saposhnikoviae Radix), and Baizhi (Angelicae Dahuricae Radix).
In summer cases of Huoluan with vomiting and diarrhea, where the patient has an intense desire for water or exhibits manic restlessness, use Jiangzhi Houpo (Ginger-processed Magnoliae Officinalis Cortex), Guanzi (Cinnamomi Cortex), Ganjiang (Zingiberis Rhizoma), Fuling (Poria), and Banxia (Pinelliae Rhizoma).
Formula for Huoluan: Huoxiang (Agastaches Herba), Cangzhu, Houpo, Chenpi, Suosha (Amomi Fructus Rotundus), Baizhi, Gancao, Banxia, Fuling, Renshen (Ginseng Radix et Rhizoma), Chao Shenqu (Fried Massa Medicata Fermentata), all in equal proportions. If cold is prominent, add Ganjiang; if cold is severe, add Fuzi (Aconiti Lateralis Radix Praeparata).
For vomiting and diarrhea type Huoluan in summer, Yi Yuan San (Benefit One Powder) mixed with ice water and ginger juice can be taken. Alternatively, Gui Ling Gan Lu Yin (Cinnamon, Poria, and Sweet Dew Drink) can be administered with Di Jiang Shui (Earth Slurry Water) or clear water; fresh well water is also acceptable, as extreme yin substances can generate yin within yang.
For mild irritability and thirst in Huoluan, Qian Shi Bai Zhu San (Dr. Qian's Atractylodes Powder) is used. Both formulas above are recorded in *Bao Jian* (*Health Treasure*). For summer vomiting and diarrhea, Huanglian Xiangru Tang (Coptis and Elsholtzia Decoction) soaked in a well until cold can be taken.
The pulse in Huoluan is often deep (Fu pulse) or imperceptible (Jue pulse); the primary treatment is Li Zhong Tang (Regulate the Middle Decoction). When Yang fails to ascend and Yin fails to descend, causing obstruction in the middle jiao leading to Huoluan, rice soup must strictly be avoided, as it can lead to death.
Summer Huoluan often results from excessive consumption of melons, fruits, and cold drinks while exposed to wind, leading to food stagnation and indigestion. This dietary retention causes Pi (glomus/blockage), obstructing the upper and lower jiao, resulting in Huoluan. It should be treated with Liu He Tang (Six Harmonies Decoction) with doubled Huoxiang.
When there is chaotic abdominal pain with inability to vomit or defecate, it is named Gan Huoluan (Dry Cholera). Gan Huoluan is the most difficult to treat and requires inducing emesis with salt water.
To treat Jiaochang Sha (Intestinal Twisting Sand, a colloquial term for severe acute abdominal pain with vomiting/diarrhea difficulty), boil Camphor Wood chips (Zhangmuxie) into a strong decoction and drink one bowl; vomiting and diarrhea will ensue shortly. (Note: Some say Gan Huoluan is commonly known as Jiaochang Sha.)
Another method involves puncturing the Weizhong point (BL40) where purple collaterals appear to release blood, which brings relief; or bleeding the tips of the ten fingers is also an effective method.
For a case of apparent death from Huoluan where warmth remains in the abdomen, place salt in the umbilicus and moxa seven cones, followed by moxa on Qihai point (CV6).
