上吐下泻转筋一症，古人立名曰霍乱，宋朝太医院立方，名曰局方，立藿香正气散以治
之。
毒流行，病吐泻转筋者数省，京都尤甚，伤人过多，贫不能葬埋者，国家发帑施棺，月余之
间，费数十万金。彼时业医者，有用参术姜附见效者，便言阴寒；有用芩连栀柏见效者，则
云毒火。余曰∶非也，不分男妇老少，众人同病，乃瘟毒也。或曰∶既是瘟毒，姜附热，芩
连凉，皆有见效者，何也？余曰∶芩连效在初病，人壮毒胜时。姜附效在毒败，人弱气衰时
。又曰∶有芩连姜附服之不效，而反有害者，何也？余曰∶试看针刺而愈者，所流尽是黑紫
血，岂不是瘟毒烧炼。瘟毒自口鼻入气管，由气管达于血管，将气血凝结，壅塞津门，水不
得出，故上吐下泻。初得，用针刺其胳膊肘里弯处血管，流紫黑血，毒随血出而愈。或曰∶
所刺是何穴？请明白指示。余曰∶余虽善针，不必论，是穴名曰尺泽。人气管周身贯通，血
管周身亦贯通，尺泽左右四五根血管，刺之皆出血，皆可愈，尺泽上下刺之亦可愈。总之，
用针所刺而愈，皆风火气有余之症，不足之症，愈针愈坏。此针灸家隐讳而不肯言也。仓卒
之时，用针刺，取其捷便也。一面针刺，一面以解毒活血汤治之，活其血，解其毒，未有不
一药而愈者。但此症得之最速，伤元气最快，一半日可伤生。若吐泻一两时后，或半日后，
一见腿抽，便是腿上气少，一见胳膊抽，便是胳膊上气少。如见眼胞塌陷，汗出如水，肢冷
如冰，谩言凉药有害，即余所立解毒活血汤，亦有过无功。此时无论舌干口燥，大渴饮冷，一
时饮水数碗，放心用姜附回阳汤，一副可夺命。此法非浅医所能知也。
上吐下泻并伴有小腿抽筋的症状，古人将其命名为霍乱。宋朝太医院制定的方剂称为“局方”，其中设立藿香正气散来治疗此病。
当时瘟疫毒邪流行，多个省份出现呕吐、腹泻及转筋（肌肉痉挛）的患者，京城地区尤为严重，死亡人数众多，贫困者无力安葬，国家动用国库资金发放棺木救济，在一个多月时间里耗费数十万两白银。当时的医生中，有人使用人参、白术、干姜、附子见效，便声称这是阴寒证；有人使用黄芩、黄连、栀子、黄柏见效，便声称这是毒火证。我说：不对，不分男女老少，众人患的是同一种病，这是瘟毒所致。有人问：既然是瘟毒，姜、附性热，芩、连性凉，为什么都有见效的情况呢？我说：芩、连见效是在疾病初期，人体正气壮实、毒邪强盛的时候；姜、附见效是在毒邪衰退、人体虚弱、元气衰败的时候。又问：有的人服用芩、连或姜、附无效，反而有害，为什么呢？我说：请看那些通过针刺治愈的案例，流出的全是黑紫色的血，这难道不是瘟毒煎熬气血造成的吗？瘟毒从口鼻进入气管，由气管到达血管，导致气血凝结，壅塞在津液通行的门户，水液无法排出，所以上吐下泻。刚发病时，用针刺其胳膊肘内侧弯曲处的血管，流出紫黑色的血，毒邪随血液排出而痊愈。有人问：刺的是什么穴位？请明确指示。我说：我虽然擅长针灸，但这不必多论，这个穴位名叫尺泽穴。人的气管贯通全身，血管也贯通全身，尺泽穴左右各有四五根血管，刺之都能出血，都能治愈，在尺泽穴上下位置针刺也能治愈。总之，用针刺治愈的，都是风火气有余的实证；如果是虚证，越针刺病情越坏。这是针灸家隐晦不肯说出来的秘密。在仓促紧急之时，采用针刺是为了取其快捷方便。一边针刺，一边用解毒活血汤治疗，以活血解毒，没有不靠这一种药就痊愈的。但是这种病发作最快，损伤元气也最快，半天之内就可能致死。如果呕吐腹泻一两个小时后，或者半天后，一见腿部抽筋，就是腿上气少；一见胳膊抽筋，就是胳膊上气少。如果见到眼睑塌陷，汗出如水，四肢冰冷如冰，不要说凉药有害，就是我设立的解毒活血汤，也是只有过错没有功效。此时无论舌干口燥，极度口渴想喝冷水，一时喝下好几碗水，放心大胆地使用姜附回阳汤，一副药就能挽回性命。这种方法不是浅薄的医生所能知道的。
The syndrome of vomiting, diarrhea, and muscle cramps (spasms) was named "Huo Luan" (Cholera-like disease) by ancient physicians. The Imperial Hospital of the Song Dynasty formulated prescriptions known as "Ju Fang" (Bureau Formulas), establishing Huoxiang Zhengqi San (Agastache Powder to Rectify the Qi) to treat it.
At that time, epidemic toxic pathogens were prevalent, with numerous cases of vomiting, diarrhea, and cramps reported in several provinces, particularly severe in the capital. The excessive mortality led to a situation where the poor could not afford burials; the state used treasury funds to distribute coffins, costing hundreds of thousands of taels of silver within a month. Among the practicing physicians at that time, some achieved results using Renshen (Ginseng Root), Baizhu (Atractylodes Macrocephala Rhizome), Jiang (Dried Ginger), and Fuzi (Prepared Aconite Root), claiming it was a Yin-Cold syndrome; others achieved results using Huangqin (Scutellaria Root), Huanglian (Coptis Rhizome), Zhizi (Gardenia Fruit), and Huangbai (Phellodendron Bark), claiming it was Toxic-Fire syndrome. I said: Incorrect. Regardless of gender or age, everyone suffered from the same illness, which was caused by Epidemic Toxin (Wen Du). Someone asked: Since it is an Epidemic Toxin, why do both the hot herbs (Jiang, Fuzi) and the cold herbs (Qin, Lian) yield effective results? I replied: Huangqin and Huanglian are effective in the early stage of the disease when the patient's constitution is strong and the toxin is vigorous. Jiang and Fuzi are effective when the toxin has declined and the patient is weak with depleted Qi. Another question arose: Why do some patients take Huangqin/Huanglian or Jiang/Fuzi without effect, and even suffer harm? I replied: Observe those cured by acupuncture; they bled dark purple blood. Is this not the result of the Epidemic Toxin refining and coagulating the blood and Qi? The Epidemic Toxin enters via the mouth and nose into the Trachea (Qi Guan), travels from the Trachea to the Blood Vessels, causing the coagulation of Blood and Qi, blocking the gates of fluid metabolism. Consequently, fluids cannot exit normally, leading to vomiting and diarrhea. In the initial stage, pricking the blood vessels in the inner bend of the elbow causes the discharge of dark purple blood, allowing the toxin to exit with the blood, resulting in cure. Someone asked: Which acupoint was punctured? Please indicate clearly. I replied: Although I am skilled in acupuncture, let us not dwell on that; the acupoint is named Chize (LU-5). The human Trachea penetrates the whole body, and so do the blood vessels. There are four or five blood vessels around Chize on both sides; puncturing any of them releases blood and can lead to recovery. Puncturing above or below Chize can also lead to recovery. In summary, cures achieved through acupuncture apply only to syndromes characterized by excess Wind, Fire, and Qi. For deficiency syndromes, acupuncture worsens the condition. This is a secret kept hidden by acupuncturists. In emergencies, acupuncture is used for its speed and convenience. While performing acupuncture, simultaneously administer Jiedu Huoxue Tang (Detoxification and Blood-Invigorating Decoction) to invigorate blood and resolve toxins; there is no case that does not recover with this single prescription. However, this disease strikes fastest and damages Yuan Qi (Original Qi) most rapidly; death can occur within half a day. If, after one or two hours or half a day of vomiting and diarrhea, leg cramps appear, it indicates a deficiency of Qi in the legs; if arm cramps appear, it indicates a deficiency of Qi in the arms. If sunken eye sockets, sweating like water, and limbs cold as ice are observed, do not merely claim that cold medicines are harmful; even my established Jiedu Huoxue Tang would be ineffective and potentially harmful. At this stage, regardless of dry tongue and mouth, extreme thirst for cold drinks, or drinking several bowls of water at once, confidently use Jiangfu Huiyang Tang (Ginger and Aconite Decoction to Restore Yang) to rescue life; a single dose can save the patient. This method is beyond the comprehension of mediocre physicians.
