霍乱之证，在夏秋为多，得之于风、寒、暑、热，饮食生冷之邪，杂糅交病于中，正不能堪，一任邪之
挥霍扰乱，故令三焦混淆，清浊相干，乱于肠胃也。其证呕吐泻利，腹中大痛，脉多微涩，或沉而伏，或大
而虚。其风甚者，则头痛寒热。寒甚者，则转筋厥冷。暑甚者，则大渴引饮。邪在上焦则吐多，下焦则泻
多，中焦则吐泻俱甚。总宜治乱保安法加减主之，风甚加苏叶、橘红，寒甚加草蔻、木瓜，暑甚加芦根、竹
茹，吐多加黄连、干姜，泻多加葛根、荷叶。倘吐泻不已，损伤中焦之气，以致阴阳间隔，手足厥冷，脉微
欲绝，不多饮水者，无分风、寒、暑、热，急以挽正回阳法救之。若欲吐不吐，欲泻不泻，名曰干霍乱
也，又名绞肠痧也，急用古方炒盐调童便，服之探吐则愈。若舌卷筋缩，卵阴入腹为难治。
大率霍乱之脉，洪大而滑者生，微涩渐迟者死。
南方之人，体气不实，偶触粪土沙秽之气，即腹痛闷乱，名
之曰痧，即沙字之讹也。盖痧在皮肤气分者，宜刮之，在肌肉
血分者，宜刺之，此轻而浅者言也。若深重者胀塞肠胃，壅阻经络，直犯乎心，斯须莫救，刮刺无功，非药
剂不能救也。须知痧无定脉，凡脉与证不应者，即为痧脉也。其见证不可不分∶如风痧者，头疼自汗，腹
痛肢麻。暑痧者，头晕汗多，吐泻腹痛。阴痧者，腹痛肢冷，即凉痧也。阳痧者，腹痛肢暖，即热痧
也。又有肤隐红点，一如 疹，此痧在肌表，为红痧也。满身胀痛，且有黑斑，此痧毒在乎脏腑，为乌痧也。
欲吐不吐，欲泻不泻，心腹大痛，为绞肠痧也。痧之为病，不尽六气所触，或因饥饱劳役，或因秽浊所犯，
皆可成痧，总宜芳香化浊法治之。法内有半夏、藿香，慎勿信俗医为痧病中之禁药也。风痧加荆
芥、防风，暑痧加滑石、木瓜，阴痧加豆蔻、砂仁，阳痧加连翘、栀子，红痧加牛蒡、薄荷，乌痧加槟榔、
枳壳，闷痧加细辛、桔梗，绞肠痧加檀香、乌药，倘其势急不及进汤药者，先以痧疫回春丹治之。
霍乱这一病证，在夏秋季节较为多见，是由风、寒、暑、热等外邪，以及饮食生冷之邪，混杂交结于体内所致。正气不能承受，只能任由邪气挥霍扰乱，从而导致三焦（上焦、中焦、下焦的总称）功能混淆，清阳与浊阴相互干扰，紊乱于肠胃之中。其症状表现为呕吐、腹泻，腹部剧烈疼痛，脉象多呈微涩，或沉伏，或大而虚。若风邪偏盛，则出现头痛、恶寒发热；寒邪偏盛，则出现转筋（肌肉痉挛）、四肢厥冷；暑邪偏盛，则出现极度口渴、大量饮水。邪气在上焦，则以呕吐为主；在下焦，则以腹泻为主；在中焦，则呕吐和腹泻都严重。总体适宜采用治乱保安法进行加减治疗，若风邪甚加紫苏叶、橘红，寒邪甚加草豆蔻、木瓜，暑邪甚加芦根、竹茹，呕吐多加黄连、干姜，腹泻多加葛根、荷叶。倘若呕吐腹泻不止，损伤了中焦之气，导致阴阳隔绝，手足厥冷，脉微欲绝，且不多饮水者，不分是风、寒、暑、何种邪气，急需用挽正回阳法来救治。如果感觉想吐却吐不出，想泻却泻不出，称为干霍乱，也称为绞肠痧，急需使用古方炒盐调童便服用，以探吐的方法治疗即可痊愈。如果出现舌体卷缩、筋脉拘急收缩、睾丸内缩入腹的情况，属于难治之症。
大抵霍乱的脉象，洪大而滑利的为顺证，预后良好；脉象微涩且逐渐变迟的为逆证，预后不良。
南方人身体元气不实，偶尔接触到粪土沙秽之气，就会腹痛闷乱，称之为“痧”，这是“沙”字的讹误。大概痧邪在皮肤气分者，适宜用刮痧疗法；在肌肉血分者，适宜用刺络放血疗法，这是针对轻浅病症而言。如果病情深重，胀塞肠胃，壅阻经络，直接侵犯心脏，片刻之间无法救治，刮痧和刺络均无效，非药物不能挽救。必须知道痧病没有固定的脉象，凡是脉象与症状不相符合的，就是痧脉。其见证表现不可不加以区分：如风痧，表现为头痛、自汗、腹痛、肢体麻木；暑痧，表现为头晕、汗多、呕吐腹泻、腹痛；阴痧，表现为腹痛、四肢冰冷，即凉痧；阳痧，表现为腹痛、四肢温暖，即热痧。又有皮肤隐现红点，如同疹子一样，这是痧邪在肌表，称为红痧；满身胀痛，且有黑斑，这是痧毒在脏腑，称为乌痧；想吐吐不出，想拉拉不出，心腹剧烈疼痛，称为绞肠痧。痧这种病，并不完全由六气（风、寒、暑、湿、燥、火）所触发，也可能因为饥饱失调、劳役过度，或者被秽浊之气侵犯，都可以形成痧病，总体适宜采用芳香化浊法治疗。该法内含有半夏、藿香，切勿听信庸医说它们是痧病的禁忌药物。风痧加荆芥、防风，暑痧加滑石、木瓜，阴痧加豆蔻、砂仁，阳痧加连翘、栀子，红痧加牛蒡子、薄荷，乌痧加槟榔、枳壳，闷痧加细辛、桔梗，绞肠痧加檀香、乌药，倘若病情紧急来不及服用汤药时，先用痧疫回春丹治疗。
The syndrome of Huoluan (cholera-like disease with vomiting and diarrhea) is more common in summer and autumn. It arises from the invasion of wind, cold, summerheat, and heat pathogens, mixed with dietary raw and cold pathogens, which confuse and attack the interior. The healthy qi cannot withstand this, allowing the pathogens to cause chaotic disturbance, leading to the confusion of Sanjiao (Triple Burner), the interference between clear and turbid yin-yang, and disorder within the intestines and stomach. Its manifestations include vomiting, diarrhea, severe abdominal pain, and a pulse that is often fine and choppy, or deep and hidden, or large and empty. If wind pathogen is predominant, headache and aversion to cold with fever occur. If cold pathogen is predominant, muscle spasms and cold extremities occur. If summerheat pathogen is predominant, extreme thirst with excessive drinking occurs. Pathogens in the Upper Jiao result in predominant vomiting; those in the Lower Jiao result in predominant diarrhea; those in the Middle Jiao result in both severe vomiting and diarrhea. Generally, it should be treated by modifying the Zhiluan Bao'an Formula (Stabilizing and Securing Method). Add Perilla Leaf (Ziye) and Tangerine Peel (Juhong) for severe wind; add Cardamom Seed (Caodoukou) and Papaya (Mugua) for severe cold; add Reed Rhizome (Lugen) and Bamboo Shavings (Zhuru) for severe summerheat; add Coptis Rhizome (Huanglian) and Dried Ginger (Ganjiang) for severe vomiting; add Kudzu Root (Gegen) and Lotus Leaf (Heye) for severe diarrhea. If vomiting and diarrhea persist, damaging the Qi of the Middle Jiao, leading to separation of Yin and Yang, cold extremities, a faint pulse nearly imperceptible, and little desire to drink water, regardless of whether the pathogen is wind, cold, summerheat, or heat, urgently rescue with the Wanzheng Huiyang Method (Restoring Healthy Qi and Returning Yang). If there is a desire to vomit but inability to do so, and a desire to defecate but inability to do so, it is called Gan Huoluan (Dry Cholera), also known as Jiaochang Sha (Intestine-Twisting Sha). Urgently use the ancient prescription of fried salt mixed with child's urine, administered to induce vomiting, which will lead to recovery. If the tongue rolls up, sinews contract, and testicles retract into the abdomen, it is difficult to treat.
Generally, a Hongda Erhua (surging, large, and slippery) pulse in Huoluan indicates survival, while a Weise Jianchi (fine, choppy, and gradually slow) pulse indicates death.
People in the South have weak constitution. Upon occasional exposure to foul air from feces, soil, sand, and filth, they experience abdominal pain and mental restlessness, termed "Sha" (a corruption of the character "Sha" meaning sand/dust). If Sha resides in the skin and Qi level, scraping therapy is appropriate; if it resides in the muscles and Blood level, pricking therapy is appropriate; this refers to mild and superficial cases. If the condition is severe, causing bloating and obstruction in the intestines and stomach, blocking meridians, and directly attacking the heart, it may become untreatable within moments, rendering scraping and pricking ineffective; only herbal medicine can save the patient. One must know that Sha has no fixed pulse; any pulse that does not correspond to the symptoms is considered a Sha pulse. The manifestations must be distinguished: Feng Sha (Wind Sha) presents with headache, spontaneous sweating, abdominal pain, and limb numbness; Shu Sha (Summerheat Sha) presents with dizziness, excessive sweating, vomiting, diarrhea, and abdominal pain; Yin Sha (Yin Sha) presents with abdominal pain and cold limbs, also called Liang Sha (Cool Sha); Yang Sha (Yang Sha) presents with abdominal pain and warm limbs, also called Re Sha (Heat Sha). There is also Hong Sha (Red Sha), characterized by hidden red spots on the skin resembling rash, indicating Sha in the muscular exterior; Wu Sha (Black Sha), characterized by whole-body distending pain and black spots, indicating Sha toxin in the Zang-Fu organs; and Jiaochang Sha (Intestine-Twisting Sha), characterized by inability to vomit or defecate despite the urge, and severe heart and abdominal pain. Sha disease is not solely caused by the Six Qi (Six Exogenous Pathogens); it can also result from irregular diet, overwork, or invasion by foul turbidity. Generally, it should be treated with the Fangxiang Huazhuo Method (Aromatic Transformation of Turbidity). This method contains Pinellia Tuber (Banxia) and Agastache Herb (Huoxiang); do not believe quacks who claim these are contraindicated in Sha diseases. For Feng Sha, add Schizonepeta Spike (Jingjie) and Saposhnikovia Root (Fangfeng); for Shu Sha, add Talcum (Huashi) and Papaya (Mugua); for Yin Sha, add Cardamom (Doukou) and Amomum Fruit (Sharen); for Yang Sha, add Forsythia Fruit (Lianqiao) and Gardenia Fruit (Zhizi); for Hong Sha, add Burdock Fruit (Niubangzi) and Mint Herb (Bohe); for Wu Sha, add Areca Seed (Binglang) and Aurantium Fruit (Zhike); for Men Sha (Stagnant Sha), add Asarum Root (Xixin) and Platycodon Root (Jiegeng); for Jiaochang Sha, add Sandalwood Wood (Tanxiang) and Lindera Root (Wuyao). If the condition is urgent and there is no time to prepare decoctions, first administer Shayi Huichun Dan (Sha Epidemic Revival Pill).
