治霍乱吐泻转筋，诸般痧证暴病，头目眩晕，咽喉肿疼，赤痢腹疼，急性淋证。
朱砂（顶高者一钱五分） 冰片（三分） 薄荷冰（二分） 粉甘草（一钱细末）
上药四味共研细，分作三次服，开水送下，约半点钟服一次。若吐剧者，宜于甫吐后急服之。若于将吐时
服之，恐药未暇
展布即吐出。服后温复得汗即愈。服一次即得汗者，后二次仍宜服之。若服完一剂未全愈者，可接续再服一剂。
若其吐泻已久，气息奄奄有将脱之势，但服此药恐不能挽回，宜接服后急救回阳汤。
朱砂能解心中窜入之毒，且又重坠，善止呕吐，俾服药后不致吐出。此方中冰片，宜用樟脑炼成者。因樟
脑之性，原善振兴心脏，通活周身血脉，尤善消除毒菌。特其味稍劣，炼之为冰片，味较清馥，且经炼，而其
力又易上升至脑，以清脑中之毒也。薄荷冰善解虎列拉之毒，西人屡发明之。且其味辛烈香窜，无窍不通，无
微不至，周身之毒皆能扫除。矧与冰片，又同具发表之性，服之能作汗解，使内蕴之邪由汗透出。且与冰片皆
性热用凉，无论症之因凉因热，投之咸宜也。粉甘草最善解毒，又能调和中宫，以止吐泻。且又能调和冰片、
薄荷冰之气味，使人服之不致过于苛辣也。
霍乱之证，西人所谓虎列拉也。因空气中有时含有此毒，而地面积秽之处，又酿有毒瓦斯与之混合（观此证
起点多在大埠不洁之处可知），随呼吸之气入肺，由肺传心胞（即心肺相连之脂膜），由心胞传三焦（上焦心
下膈膜，中焦包脾连胃脂膜，下焦络肠包肾脂膜），为手厥阴、少阳脏腑之相传。然其毒入三焦，其人中气
充盛，无隙可乘，犹伏而不动。有时或饮食过量，或因寒凉伤其脾胃，将有吐泻之势，毒即乘虚内袭，盘据胃
肠，上下不通，遂挥霍撩乱，而吐泻交作矣。吐泻不已，其毒可由肠胃而入心，更由心而上窜于脑，致脑髓神
经与心俱病。左心房输血之力与右心房收血之力，为之顿减，是以周身血脉渐停，而通体皆凉也。其证多发于
秋际者，因此毒瓦斯酿成多在夏令。人当暑热之时，周身时时有汗，此毒之伏于三焦者，犹得随汗些些外出。迨
至秋凉汗闭，其毒不得外出，是以蓄极而动，乘脾胃之虚而内攻也。故治此症者，当以解毒之药为主，以助心
活血之药为佐，以调阴阳奠中土之药为使。爰拟此方，名之曰急救回生丹。

前次寄来急救回生丹方，不知何以斟酌尽善。初故城闹疫，按方施药六十剂，皆随手辄效。后故城外镇郑
家口闹疫，又施药二百剂，又莫不全活。
治疗霍乱引起的呕吐腹泻及转筋，各种痧证突发急病，头目眩晕，咽喉肿痛，赤痢腹痛，急性淋证。
朱砂（选用质地最高级的1.5钱） 冰片（3分） 薄荷冰（2分） 粉甘草（1钱，研成细末）
以上四味药共同研磨成细粉，分为三次服用，用开水送服，大约每半小时服用一次。如果呕吐剧烈，应当在刚吐完后立即服用。如果在将要呕吐时服用，恐怕药物还没来得及发挥作用就被吐出。服药后若盖被保暖并出汗，即可痊愈。如果服用第一次就出了汗，后两次仍应继续服用。如果服完一剂药仍未完全痊愈，可以接着再服一剂。
如果呕吐腹泻时间已久，气息微弱有虚脱的危险迹象，单服此药恐怕难以挽回，应当接续服用后文的“急救回阳汤”。
朱砂能解除心中窜入的毒邪，且质地沉重下沉，善于止住呕吐，使服药后不至于吐出。此方中的冰片，宜选用由樟脑炼制而成的。因为樟脑的药性，原本善于振奋心脏功能，疏通周身血脉，尤其善于消除毒菌。只是它的气味稍差，炼制成冰片后，气味较为清香馥郁，而且经过炼制，其药力更容易上升至脑部，以清除脑中的毒邪。薄荷冰善于解除虎列拉（霍乱）的毒邪，西方人对此多有阐发。况且它气味辛烈香窜，无处不到，无微不至，周身之毒皆能扫除。何况它与冰片，又都具有发表透邪的性质，服用后能促使出汗解表，使体内蕴积的病邪通过汗液透出。且它们都性热而用凉，无论病症是因寒凉还是因热邪引起，投用都非常适宜。粉甘草最善于解毒，又能调和脾胃（中宫），以止住呕吐和腹泻。而且又能调和冰片、薄荷冰的气味，使人服用时不至于感到过于辛辣刺激。
霍乱的病症，西方人称为虎列拉（Cholera）。因为空气中有时含有这种毒邪，而地面堆积污秽之处，又酝酿出有毒瓦斯与之混合（观察此病起点多在不洁净的大城市可知），随着呼吸之气进入肺部，由肺传至心包（即心肺相连的脂膜），由心包传至三焦（上焦是心下膈膜，中焦是包裹脾脏连接胃腑的脂膜，下焦是联络肠道包裹肾脏的脂膜），这是手厥阴经与手少阳经脏腑之间的相传。然而毒邪侵入三焦，如果患者中气充盛，没有空隙可乘，毒邪就会潜伏而不发作。有时因为饮食过量，或因寒凉损伤脾胃，出现将要呕吐腹泻的趋势，毒邪便乘虚内袭，盘踞在胃肠，导致上下不通畅，于是挥霍撩乱，呕吐和腹泻交替发作。呕吐腹泻不止，毒邪可由肠胃进入心脏，更由心脏向上窜扰至脑部，导致脑髓神经与心脏同时患病。左心房输血的力量与右心房收血的力量，因此骤然减弱，所以周身血脉逐渐停止流动，全身变凉。此病多发于秋季，是因为这种毒瓦斯多在夏季酝酿而成。人在暑热之时，周身时常出汗，潜伏在三焦的这种毒邪，尚能随着汗水少许排出体外。等到秋凉汗孔闭合，毒邪无法外出，因此蓄积至极而发动，乘脾胃虚弱之机向内攻伐。所以治疗此症，当以解毒的药物为主，以辅助心脏活血的药物为佐使，以调和阴阳、稳固脾胃的药物为使。于是拟定此方，命名为急救回生丹。

直隶省故城县袁××来信：
上次寄来的急救回生丹方子，不知是如何斟酌得如此完善。起初故城发生疫情，按照方子施药六十剂，都是随手见效。后来故城外镇郑家口发生疫情，又施药二百剂，也都全部救活。
Treats cholera with vomiting, diarrhea, and muscle cramps; various sudden acute conditions of Sha syndrome (sand poisoning); dizziness of the head and eyes; swelling and pain in the throat; bloody dysentery with abdominal pain; and acute strangury.
Cinnabar (Zhu Sha) (1.5 qian of the highest grade)
Borneol (Bing Pian) (3 fen)
Mint Ice (Bohe Bing) (2 fen)
Powdered Licorice Root (Fen Gan Cao) (1 qian, finely powdered)
Grind these four medicines together into a fine powder, divide into three doses, and take orally with warm boiled water, approximately once every half hour. If vomiting is severe, it should be taken immediately after vomiting subsides. If taken before vomiting occurs, there is a fear that the medicine will not have time to act before being vomited out. After taking the medicine, if warmth is applied to induce sweating, recovery will occur. If sweating occurs after the first dose, the subsequent two doses should still be taken. If the patient is not fully recovered after one full dose, another dose may be taken consecutively.
If vomiting and diarrhea have persisted for a long time, breath is faint, and there are signs of impending collapse, this medicine alone may not be able to reverse the condition; it is advisable to subsequently administer the Emergency Rescue Yang-Returning Decoction (Ji Jiu Hui Yang Tang).
Cinnabar can resolve toxins invading the heart, and due to its heavy and sinking nature, it is good at stopping vomiting, ensuring the medicine is not vomited out after ingestion. The Borneol in this formula should be made from refined Camphor (Zhang Nao). This is because Camphor naturally revitalizes the heart and promotes blood circulation throughout the body, and is particularly effective in eliminating pathogenic bacteria. Although its taste is slightly inferior, refining it into Borneol makes the taste more fragrant and pure. Furthermore, after refinement, its therapeutic power rises more easily to the brain to clear toxins there. Mint Ice is effective in resolving the toxin of Cholera (Hu Lie La), as frequently elucidated by Western scholars. Moreover, its pungent, acrid, and aromatic nature penetrates all orifices and reaches every part of the body, sweeping away toxins throughout. In addition, like Borneol, it possesses the property of releasing the exterior; taking it induces sweating, allowing internal pathogens to be expelled through sweat. Both are hot in nature but used in cool applications, making them suitable regardless of whether the disease is caused by cold or heat. Powdered Licorice Root is best at detoxifying, harmonizing the Middle Jiao (Spleen and Stomach) to stop vomiting and diarrhea, and harmonizing the tastes of Borneol and Mint Ice so that patients do not find them overly harsh or spicy.
The disease known as Cholera is referred to by Westerners as "Hu Lie La" (Cholera). Sometimes the air contains this toxin, which mixes with toxic gases generated from accumulated filth on the ground (as can be seen from the fact that outbreaks often start in unclean urban areas). It enters the lungs via respiration, transmits from the Lungs to the Pericardium (the fatty membrane connecting the heart and lungs), and then from the Pericardium to the Triple Burner (San Jiao). The Upper Jiao is the diaphragm below the heart; the Middle Jiao is the fatty membrane enveloping the Spleen and connecting to the Stomach; the Lower Jiao is the fatty membrane linking the intestines and enveloping the Kidneys. This represents the transmission between the Hand Jueyin and Hand Shaoyang organ systems. However, when the toxin enters the Triple Burner, if the patient's Middle Qi is robust with no gaps for the pathogen to exploit, it remains latent and inactive. Occasionally, due to overeating or damage to the Spleen and Stomach by cold and coolness, leading to a tendency toward vomiting and diarrhea, the toxin takes advantage of the deficiency to invade internally, lodging in the Stomach and Intestines. This causes obstruction of the upper and lower passages, resulting in chaotic turmoil with alternating vomiting and diarrhea. If vomiting and diarrhea persist, the toxin can enter the Heart from the Gastrointestinal tract and further ascend to the Brain, causing disease in both the brain marrow/nerves and the Heart. Consequently, the pumping force of the left atrium and the collecting force of the right atrium decrease abruptly, causing the blood vessels throughout the body to gradually cease flow and the entire body to become cold. This disease often occurs in autumn because this toxic gas is mostly generated during summer. During the heat of summer, the body sweats frequently, allowing some of the toxin latent in the Triple Burner to be excreted with sweat. When autumn cools and sweating stops, the toxin cannot exit, accumulates to an extreme, and then attacks inwardly taking advantage of the deficiency of the Spleen and Stomach. Therefore, treating this condition should primarily use detoxifying herbs, assist with herbs that support the Heart and invigorate blood, and use harmonizing herbs that stabilize the Middle Earth (Spleen/Stomach) and balance Yin and Yang as guides. Thus, this formula was devised and named Emergency Rescue Reviving Pill (Ji Jiu Hui Sheng Dan).
Appendix:
Letter from Yuan XX of Gucheng County, Zhili Province:
I do not know how you carefully refined the formula for Emergency Rescue Reviving Pill sent previously. Initially, when an epidemic broke out in Gucheng, I dispensed sixty doses according to the formula, all of which were effective immediately. Later, when an epidemic broke out in Zhengjiakou, a town outside Gucheng, I dispensed two hundred doses, all of which resulted in complete recovery.
