Tian Xuefan (courtesy name Jinyuan, a *Juren* degree holder) from Shanyin authored the book *Shixing Huoluan Zhimi Bianzheng* (Clarifying and Correcting Epidemic Cholera). The condition commonly known in secular terms as "Diaojiao Sha" (Hanging Leg Cholera) is considered to be true cold pathogen directly invading the *Jueyin Liver Meridian*, which is precisely *Huoluan Zhuanjin* (Cholera with Muscle Cramps). At the onset, there is initially abdominal pain, or sometimes no pain, followed by diarrhea of clear water, occurring dozens of times within a short period, or at least ten-plus times. Soon after, cramping and pulling of the tendons in the hands occur, accompanied by vomiting and regurgitation, intense thirst with excessive drinking, cold limbs (*Jue Ni*), and a faint pulse nearly imperceptible. In severe cases, hoarseness, a shortened tongue, upward deviation of the eyes, cyanosis of the hands and feet, or stiff, rope-like protrusion of blue veins over the entire body may appear, along with sweating and absence of pulse. Acute cases may result in death from morning to evening or evening to morning; slower cases may lead to death within two to three days or five to six days. Physicians of the world often misdiagnose this as *Shushi* (Summerheat-Dampness) and recklessly administer cooling purgatives, or misdiagnose it as *Sha Qi* (Sha Poison) and recklessly administer aromatic dispersants (such as *Shixiang Wan* [Ten-Aromatic Pill] or *Wolong Dan* [Sleeping Dragon Pill]), rarely failing to cause death. The appropriate prescription is *Danggui Sini Jia Wuzhuyu Shengjiang Tang* (Angelica Sinensis Decoction for Cold Extremities plus Evodia and Ginger) [Dang Gui 2 qian, Chao Baishao 1.5 qian, Guizhi 1.5 qian, Zhi Cao 1 qian, Tongcao 1 qian, Wuzhuyu 1.5 qian, Xixin 8 fen, Shengjiang 3 slices, Hei Zao 3 pieces, decocted in water and taken cold]. Mild cases recover after taking two or three doses (administered frequently throughout one day); severe cases recover immediately after taking several more doses. It is truly a miraculous formula, effective in every case. If vomiting is present, add Jiangzhi Banxia (Ginger-processed Pinellia Rhizome) 3 qian and Danganjiang (Lightly Dried Ginger) 1 qian to the base formula. If there is intense thirst with excessive drinking and a yellow tongue coating, add Jiangchao Chuanlian (Ginger-fried Coptis Rhizoma) 0.5 fen as an antagonistic agent, following the classic principle of "treating heat with cold administration" (*Re Yin Han Yong*). If there is colicky abdominal pain and various cramps pulling into the abdomen, add Jiuchao Mugua (Wine-fried Chaenomelis Fructus) 3 qian. If the hands are cold beyond the elbows and knees, and the skin shows cyanosis, add Zhifu Zi (Prepared Aconite Lateralis Radix) 3 qian. If there is hoarseness, upward deviation of the eyes, curled tongue, and retracted scrotum, with an absent pulse, it is an untreatable condition; medication will be too late. One should quickly employ moxibustion therapy. (At the *Guanyuan* CV4 acupoint, located three cun below the umbilicus, crush Fu Zi (Aconite Lateralis Radix Preparata) into a cake the size of a coin, place it on the acupoint, and apply a moxa cone the size of a longan nut on top. Moxibustion for fourteen *Zhuang*; for severe cases, thirty *Zhuang*. Recovery occurs when vomiting and diarrhea stop and extremities warm up. If Fu Zi is unavailable, slice fresh Shengjiang (Fresh Ginger Rhizome) to the size of a coin and apply it for moxibustion; even direct skin moxibustion without ginger is excellent. When warmth is felt deep inside the abdomen, vomiting and diarrhea gradually cease. To measure one *cun*, use the length of the middle segment of the patient's middle finger as the standard, using a grass stem to mark the measurement accurately without cutting it; simply folding it three times yields three *cun*.) These various symptoms all manifest in the Liver Meridian and are caused by cold pathogen. The confusing aspects are the thirst, yellow tongue coating, preference for cold drinks, and aversion to clothing/bedding. This is because the True Yang in the Kan palace is forced outward by the cold pathogen, leading to its dispersion—described as "true cold inside and false heat outside." By differentiating based on the pulse, there should be no hesitation. Some physicians accustomed to using warming and tonifying methods know this condition is Yin-Cold and treat it with *Fuzi Lizhong Tang* (Aconite Decoction to Regulate the Middle) or *Sini Tang* (Reverse the Cold Decoction) to warm and tonify the Spleen and Kidney. However, since these do not directly target the Jueyin Liver Meridian, they still fail to produce results. I observe that since the Gengchen year of the Jiaqing reign, patients have been continuous, with the disease progressing rapidly. If physicians do not follow proper protocols, death ensues instantly, yet medical texts rarely detail treatment methods. I hereby describe it thoroughly to benefit future generations.

Xu Xinmu stated: There is nothing more exquisite for treating Diaojiao Sha than *Laifu Dan* (Return to Life Pill). However, the Sulfur used must be genuine Japanese origin; if local sulfur is used, it is ineffective. Furthermore, if this pill is taken in small pellets, it often induces vomiting. Only when made into large pills and crushed into powder before administration will it work; even if vomiting occurs, not all medicine is expelled. After repeated dosing and vomiting, once the medicinal properties take effect, vomiting ceases and recovery follows. It should be taken down with strong, spicy ginger soup. In the Xinsi year of the Daoguang reign, this disease was prevalent, and some recovered by frequently consuming crushed concentrated ginger juice.
