雷公真君曰∶中暑亡阳，汗出不止，立时气脱者，死症也。盖亡阳则阳气尽从汗出，故气尽
而死。法当急补其阳气，则阳气接续阴气，而不至有遽脱之忧，用独参汤妙矣，而贫家何从得参，
不若以当归补血汤。用当归一两；黄 二两，加桑叶三十片救之。盖二味价廉，而功亦不亚于人
参，且桑叶又有补阴之功，无阴则阳不化∶黄 补气，得当归则补血，得桑叶则尤能生阴也。
中暑发狂，气喘，汗如雨下，如丧神失守，亦死亡顷刻也。盖热极无水以养神，心中自焚，逼汗
于外，亡阳而且失神也，急宜用白虎汤救之。然少亦不济也，必须石膏用四两，人参亦用四两，加黄连
三钱，水煎服。一剂而神定，二剂而汗止矣。或疑心中无水，而身何以有汗。不知发狂之症，口未有
不渴者。口渴必饮水自救，水入腹中，不行心而行脾，脾必灌注于肺，肺主皮毛，故从外泄。然则汗
乃外来之水，非内存之液也。况汗从外泄，阳气亦从之而出，阳出而心中之阴气亦且随之而散亡，所以
丧神失守耳。吾以黄连平其心火，石膏除其胃火，而大加人参以救其亡阳之脱，庶几火散而正气独存，神
存而外邪皆失也。
中暑循衣摸床，以手撮空，本是死症。然而可救者，以
暑气之在心，解心中之热，则五脏即有生气，方用独参汤三两，加黄连三钱灌之，而循衣摸床、撮
空等症遽止者即生。盖人参救心气之绝，而黄连散心中之火，火散气回，其生也必矣。
中暑猝倒，心痛欲死者。不治之症也。暑气最热，而心乃火宫，以火入火，何以相犯而竟至心痛
欲死也。不知心火，君火也；暑火，邪火也。邪火凌心，与邪水浸心，原无彼此之异。故寒暑之气不
犯则已，犯则未有不猝然心痛者也。心君至静，有膻中之间隔，犯心者犯膻中也。邪犯膻中，便猝
然心痛，此时即以祛暑之药，直引入膻中，则暑散火退，而心君泰然也。方用散暑救心汤∶青蒿一两，
黄连三钱，人参三钱，茯神五钱，白术三钱，香薷一钱，藿香五钱，半夏一钱，水煎服。一剂而痛即
止。此方神效者，妙在青蒿同用，直入膻中，逐暑无形，所以止痛如响耳。
中暑忽倒，口吐白沫，将欲发狂，身如火烧，紫斑烂然者，多不可救，而予谓有一线可救者，
正以其紫斑之发出也。倘不发出，则火毒内藏，必至攻心而亡。今嫌其斑虽发出，而其色纯紫，则毒瓦斯
太盛，恐难化耳。方用救斑再苏汤∶元参三两，升麻三钱，荆芥三钱，黄连三钱，黄芩三钱、麦冬
三两，天冬一两，青蒿一两，水煎服。一剂而斑色变红，再剂而斑红变淡，三剂而斑色尽消，便庆再
苏也。否则终亦必亡而已矣。
夏日感暑，至生霍乱，欲吐而不能，不吐不可，最急之病也，用香薷饮亦得生。然有用之而不
纳，随饮即吐，尤为至凶，法当从治，我有妙方，名转治汤。白术三钱，茯苓三钱，芍药五钱，藿香一
钱，紫苏五分，陈皮五分，天花粉一钱，肉桂五分，香薷五分，白豆蔻一粒，水煎冷服，下喉即

霍乱腹痛，欲吐不能，欲泻不得，四肢厥逆，身青囊缩，必死之症也。予亦何必再为立方。然而
其人一刻不亡，岂可听之而不救乎。此症乃下虚寒，而上感暑热之气，阴阳拂乱。上下不接，最危最
急之候。法当用阴阳水探吐之。若不应，急以救乱汤治之。人参五钱，香薷三钱，吴茱萸三钱，茯苓
三钱，白术三钱，附子五分，藿香一钱，木瓜三钱，水煎服。下喉而气即回矣，真治干霍乱之神
方也。若湿霍乱，又不可用此方，用白术五钱，香薷一钱，青蒿五钱，茯苓五钱，陈皮一钱，砂仁三
粒，一剂即回春也。
产后忽感中暑，霍乱吐泻，法在不救。然而亦有用药救之而能生者。总不可用香薷也，方用消
暑活产丹∶人参一两，当归二两，川芎一两，肉桂二钱，青蒿一钱，水煎服。一剂即愈。盖产妇止补
气血，气血既回，暑气自散，况方中又有祛寒解暑之味乎，所以奏功独神也。或疑感暑是热，胡为
反用肉桂。不知产妇气血大虚，遍身是寒，一感暑气，便觉相拂，非有大热之气深入腹中也，不过略感暑
气，与本身之寒两相攻击，以致霍乱。今仍用肉桂以温其虚寒，以青蒿而解其微暑，用之于大剂补气
补血之中，是以驾御而不敢有变乱之形，此立方之妙，而建功之神也，又何必疑哉。
夏令火热，烁石流金，人有一时感犯暑邪、上吐下泻，立刻死者，最可惧之症也。切勿轻用香
薷饮，亦莫妄用白虎汤。我有一方，名曰解热消暑散。青蒿一两，干葛一钱，香薷一
钱，茯苓一两，白术三钱，白扁豆二钱，陈皮一钱，治之即安。此方妙在用青蒿、茯苓为君。青蒿最能
解暑而去热，一物而两用之，引其暑热尽从膀胱而出，而干葛、香薷之类，不过佐青蒿以去暑也。尤
妙少用白术以健脾胃之气，则暑热退而胃气不伤，胜于香薷饮多矣。
雷公真君说：中暑导致亡阳，汗出不止，随即气脱的，是死症。因为阳气耗尽都随汗液排出，所以气尽而死。治疗应当紧急补益阳气，使阳气接续阴气，从而避免突然脱失的危险，使用独参汤非常妙，但贫寒人家哪里能得到人参，不如用当归补血汤。用当归一两；黄芪二两，加桑叶三十片来救治。这两味药价格便宜，功效也不亚于人参，而且桑叶又有补阴的作用，没有阴液则阳气无法化生：黄芪补气，得到当归就能补血，得到桑叶则更能生阴。
中暑出现发狂、气喘、汗如雨下，如同神灵丧失守舍，也是顷刻间死亡的症状。这是因为热极无水以养神，心中自焚，逼迫汗液外泄，既亡阳又失神，应当紧急使用白虎汤来救治。然而用量少也无济于事，必须用石膏四两，人参也用四两，加黄连三钱，水煎服。一剂后神志安定，两剂后汗止。有人怀疑心中无水，身体怎么会有汗？不知道发狂的病人，口中无不感到口渴的。口渴必然饮水自救，水进入腹中，不运行于心而运行于脾，脾必然灌注于肺，肺主皮毛，所以从体表泄出。那么汗乃是外来的水，不是体内原有的津液。况且汗从体表泄出，阳气也随之外出，阳气外出则心中的阴气也随之散失亡脱，所以导致丧神失守。我用黄连平抑心火，石膏清除胃火，并大量加入人参来挽救亡阳之脱失，这样火势消散而正气独存，神志保存而外邪皆失。
中暑出现循衣摸床（手指无意识地抓摸衣物和床沿）、撮空理线（手在空中虚抓），本是死症。然而可以救治的，是因为暑气在心，解除心中的热，五脏就会恢复生气，方用独参汤三两，加黄连三钱灌服，循衣摸床、撮空等症状立即停止的就是能活。因为人参挽救心气的绝脱，而黄连疏散心中的火，火散气回，生存就必然了。
中暑突然昏倒，心痛欲死的，是不治之症。暑气最热，而心是火脏，以火入火，为何相互侵犯竟至心痛欲死？不知道心火是君火；暑火是邪火。邪火凌犯心脏，与邪水浸渍心脏，原本没有区别。所以寒暑之气如果不侵犯人体则已，一旦侵犯，没有不突然心痛的。心君极其安静，有膻中作为间隔，侵犯心的其实是侵犯膻中。邪气侵犯膻中，便突然心痛，此时即用祛暑的药物，直接引入膻中，则暑散火退，心君安然无恙。方用散暑救心汤：青蒿一两，黄连三钱，人参三钱，茯神五钱，白术三钱，香薷一钱，藿香五钱，半夏一钱，水煎服。一剂后疼痛即止。此方神效的原因，妙在青蒿同用，直入膻中，驱逐无形的暑气，所以止痛如响。
中暑突然昏倒，口吐白沫，将要发狂，身体如火烧，紫斑明显可见的，大多不可救，但我认为有一线生机，正是由于紫斑发出。如果不发出，则火毒内藏，必至攻心而亡。现在嫌弃斑虽发出，但其色纯紫，则毒瓦斯太盛，恐怕难以化解。方用救斑再苏汤：玄参三两，升麻三钱，荆芥三钱，黄连三钱，黄芩三钱，麦冬三两，天冬一两，青蒿一两，水煎服。一剂后斑色变红，两剂后斑红变淡，三剂后斑色尽消，便可庆幸再次苏醒。否则最终必然死亡。
夏日感受暑邪，进而产生霍乱，想吐却吐不出，不吐又不行，是最急迫的病，用香薷饮也能生还。然而有用香薷饮却不服纳，随饮即吐的，更是极为凶险，治疗方法应当顺从病势，我有妙方，名叫转治汤。白术三钱，茯苓三钱，芍药五钱，藿香一钱，紫苏五分，陈皮五分，天花粉一钱，肉桂五分，香薷五分，白豆蔻一粒，水煎冷服，下喉即可受纳，霍乱即定。此方的妙处，妙在用芍药为君药，辅以白术、茯苓，则肝气自然平和，不克制脾土，则霍乱自然平息，况且还有解暑的药物。尤其妙在用肉桂、香薷、藿香这些温热的药物，顺应暑热之气，引导邪气下行，暗中化解纷乱，这实在是有神鬼难测的机理，运用在方寸之间。
霍乱腹痛，想吐不能，想泻不得，四肢厥冷，身青囊缩（睾丸收缩），是必死的症状。我又何必再开方子。然而这个人一刻未死，岂可听之任而不救？此症乃下焦虚寒，而上部感受暑热之气，阴阳紊乱。上下不相接应，是最危重最急迫的候象。治疗方法应当用阴阳水探吐。如果无效，紧急用救乱汤治疗。人参五钱，香薷三钱，吴茱萸三钱，茯苓三钱，白术三钱，附子五分，藿香一钱，木瓜三钱，水煎服。下喉后气即回，真是治疗干霍乱的神方。如果是湿霍乱，又不可用此方，用白术五钱，香薷一钱，青蒿五钱，茯苓五钱，陈皮一钱，砂仁三粒，一剂即可回春。
产后忽然感受中暑，霍乱吐泻，法度上认为是不治之症。然而也有用药救治而能活的。总之不可用香薷，方用消暑活产丹：人参一两，当归二两，川芎一两，肉桂二钱，青蒿一钱，水煎服。一剂即愈。因为产妇只需补气血，气血既已恢复，暑气自然消散，况且方中又有祛寒解暑的药味，所以奏效特别神奇。有人疑惑感暑是热证，为何反而用肉桂？不知道产妇气血大虚，遍身寒冷，一旦感受暑气，便觉得相互抵触，并非有大热之气深入腹中，不过是略感暑气，与本身的寒气相互攻击，以致霍乱。现在仍用肉桂以温其虚寒，用青蒿以解其微暑，在大剂补气补血之中使用，因此驾驭得当而不敢有变乱之形，这是立方的妙处，建功的神奇之处，又何必怀疑呢。
夏令火热，石裂金流，人有一时感受暑邪，上吐下泻，立刻死亡的，是最可怕的病症。切勿轻用香薷饮，也不要妄用白虎汤。我有一个方子，名叫解热消暑散。青蒿一两，干葛一钱，香薷一钱，茯苓一两，白术三钱，白扁豆二钱，陈皮一钱，治疗即安。此方妙在用青蒿、茯苓为君药。青蒿最能解暑去热，一物两用，引导暑热尽从膀胱而出，而干葛、香薷之类，不过是辅助青蒿以去暑。尤其妙在少用白术以健脾胃之气，则暑热退而胃气不伤，胜过香薷饮多了。
Lei Gong Zhen Jun said: Heatstroke leading to the collapse of Yang Qi, with incessant sweating and immediate Qi exhaustion, is a fatal condition. This is because when Yang Qi collapses, all Yang Qi is lost through sweat, leading to death due to Qi exhaustion. The treatment method should urgently tonify Yang Qi, so that Yang Qi connects with Yin Qi, avoiding the danger of sudden collapse. Using Dushen Tang (Single Ginseng Decoction) is excellent, but how can poor families obtain ginseng? It is better to use Danggui Buxue Tang (Angelica Sinensis Decoction for Tonifying Blood). Use Dang Gui (Dong Quai Root) one liang; Huang Qi (Astragalus Root) two liang, add thirty leaves of Sang Ye (Mulberry Leaf) to save the patient. These two herbs are inexpensive, and their efficacy is not inferior to ginseng. Moreover, Sang Ye has the function of nourishing Yin; without Yin, Yang cannot be transformed. Huang Qi tonifies Qi; combined with Dang Gui, it tonifies Blood; combined with Sang Ye, it generates Yin even more effectively.
Heatstroke causing mania, panting, and profuse sweating like rain, resembling the loss of spirit and mental control, is also a death sentence within moments. This is because extreme heat lacks water to nourish the spirit, causing internal burning, forcing sweat outwards, resulting in both Yang collapse and spirit loss. Urgent rescue with Baihu Tang (White Tiger Decoction) is required. However, a small dose is ineffective; one must use Shi Gao (Gypsum Fibrosum) four liang, Ren Shen (Ginseng Root) four liang, add Huang Lian (Coptis Rhizome) three qian, decoct in water and take orally. After one dose, the spirit settles; after two doses, sweating stops. Some may doubt: if there is no water in the heart, why is there sweat? One does not know that patients with mania invariably have thirst. Thirst compels them to drink water to save themselves. Water entering the abdomen does not circulate in the Heart but moves to the Spleen. The Spleen then transports it to the Lung. Since the Lung governs the skin and hair, the fluid is excreted externally. Thus, this sweat is external water, not internal body fluids. Furthermore, as sweat is excreted externally, Yang Qi also exits with it. When Yang exits, the Yin Qi in the Heart also dissipates and is lost, hence the loss of spirit and mental control. I use Huang Lian to calm Heart Fire, Shi Gao to clear Stomach Fire, and add large amounts of Ren Shen to rescue collapsing Yang Qi. In this way, fire dissipates while righteous Qi remains alone; spirit is preserved, and external pathogens are defeated.
Heatstroke manifesting as grasping at clothes and bed edges (xun yi mo chuang), and picking at empty air (cuo kong), is originally a fatal condition. However, it can be rescued by clearing the heat in the Heart caused by summer-heat. Once the Heart heat is resolved, the Five Viscera regain vitality. The prescription is Dushen Tang (Single Ginseng Decoction) three liang, added with Huang Lian (Coptis Rhizome) three qian, administered via灌 (gavage). If symptoms like grasbing at clothes and picking at air cease suddenly, the patient will live. This is because Ren Shen rescues the perishing Heart Qi, while Huang Lian disperses Heart Fire. With fire dispersed and Qi returning, survival is certain.
Heatstroke causing sudden collapse and severe heart pain approaching death is an incurable condition. Summer-heat is extremely hot, and the Heart is the palace of Fire. How can fire invade fire to cause such severe heart pain? One must understand that Heart Fire is Ministerial Fire (Jun Huo); Summer-heat Fire is Pathogenic Fire (Xie Huo). Pathogenic Fire harassing the Heart is no different from pathogenic water flooding the Heart. Therefore, cold or summer-heat qi, if it does not invade, is fine; but once it invades, sudden heart pain invariably occurs. The Heart Monarch is extremely still, separated by the Dan Zhong (Pericardium). What invades the Heart actually invades the Dan Zhong. When pathogens invade the Dan Zhong, sudden heart pain occurs. At this moment, using heat-resolving medicines directly introduced into the Dan Zhong will disperse summer-heat and retreat fire, leaving the Heart Monarch tranquil. The prescription is San Shu Jiu Xin Tang (Dispersing Summer-heat Rescuing Heart Decoction): Qing Hao (Artemisia Annua Herb) one liang, Huang Lian (Coptis Rhizome) three qian, Ren Shen (Ginseng Root) three qian, Fu Shen (Poria with Hostwood) five qian, Bai Zhu (Atractylodes Macrocephala Rhizome) three qian, Xiang Ru (Elsholtzia Herb) one qian, Huo Xiang (Patchouli Herb) five qian, Ban Xia (Pinellia Tuber) one qian. Decoct in water and take orally. Pain ceases after one dose. The miraculous effect of this formula lies in the use of Qing Hao, which enters the Dan Zhong directly, driving away formless summer-heat, thus stopping pain instantly.
Sudden collapse in heatstroke, foaming at the mouth, impending mania, body burning like fire, and obvious purple macules indicate a condition mostly incurable. However, I believe there is a sliver of hope precisely because the macules have erupted. If they do not erupt, fire-toxin remains internal, inevitably attacking the Heart and causing death. Now, although the macules have erupted, their pure purple color indicates excessive toxin, making resolution difficult. The prescription is Jiu Ban Zai Su Tang (Rescuing Macules Restoring Life Decoction): Xuan Shen (Scrophularia Root) three liang, Sheng Ma (Cimicifuga Rhizome) three qian, Jing Jie (Schizonepeta Spike) three qian, Huang Lian (Coptis Rhizome) three qian, Huang Qin (Scutellaria Root) three qian, Mai Dong (Ophiopogon Tuber) three liang, Tian Dong (Asparagus Tuber) one liang, Qing Hao (Artemisia Annua Herb) one liang. Decoct in water and take orally. After one dose, macule color turns red; after two doses, red fades; after three doses, macules disappear completely, signaling recovery. Otherwise, death is inevitable.
Summer heatstroke leading to Huoluan (Cholera-like syndrome with vomiting and diarrhea), where one wants to vomit but cannot, and cannot bear not vomiting, is an urgent condition. Xiang Ru Yin (Elsholtia Decoction) can save life. However, if the patient rejects the medicine, vomiting immediately upon ingestion, it is extremely critical. The treatment method should follow the disease's trend. I have a miraculous formula named Zhuan Zhi Tang (Turning Treatment Decoction). Bai Zhu (Atractylodes Macrocephala Rhizome) three qian, Fu Ling (Poria) three qian, Shao Yao (Peony Root) five qian, Huo Xiang (Patchouli Herb) one qian, Zi Su (Perilla Leaf) five fen, Chen Pi (Citrus Reticulata Peel) five fen, Tian Hua Fen (Trichosanthes Root) one qian, Rou Gui (Cinnamon Bark) five fen, Xiang Ru (Elsholtzia Herb) five fen, Bai Dou Kou (Black Cardamom Seed) one grain. Decoct in water, cool, and take orally. The medicine is retained upon swallowing, and Huoluan stabilizes. The brilliance of this formula lies in using Shao Yao as the sovereign herb, assisted by Bai Zhu and Fu Ling, thereby calming Liver Qi. If Liver Qi does not overact on Spleen Earth, Huoluan resolves naturally. Moreover, it contains heat-resolving herbs. Especially brilliant is the use of warming herbs like Rou Gui, Xiang Ru, and Huo Xiang to comply with summer-heat qi, guiding pathogens downward, and secretly resolving chaos. This possesses divine and unpredictable mechanisms applied within the dosage.
Huoluan with abdominal pain, inability to vomit or defecate, cold limbs, cyanosis, and retracted testicles (Nang Suo) is a fatal condition. Why should I prescribe further? However, as long as the person is not dead, how can we abandon them to die? This condition involves lower deficiency-cold and upper summer-heat invasion, causing chaotic Yin-Yang and disconnection between upper and lower. It is the most critical and urgent state. The method is to induce vomiting with Yin-Yang Water. If ineffective, urgently treat with Jiu Luan Tang (Rescuing Chaos Decoction). Ren Shen (Ginseng Root) five qian, Xiang Ru (Elsholtzia Herb) three qian, Wu Zhu Yu (Evodia Fruit) three qian, Fu Ling (Poria) three qian, Bai Zhu (Atractylodes Macrocephala Rhizome) three qian, Fu Zi (Aconite Lateral Root) five fen, Huo Xiang (Patchouli Herb) one qian, Mu Gua (Chaenomeles Fruit) three qian. Decoct in water and take orally. Qi returns immediately upon swallowing. This is truly a divine formula for treating Gan Huoluan (Dry Cholera). For Shi Huoluan (Wet Cholera), this formula is contraindicated. Instead, use Bai Zhu (Atractylodes Macrocephala Rhizome) five qian, Xiang Ru (Elsholtzia Herb) one qian, Qing Hao (Artemisia Annua Herb) five qian, Fu Ling (Poria) five qian, Chen Pi (Citrus Reticulata Peel) one qian, Sha Ren (Amomum Fruit) three grains. One dose brings spring-like recovery.
Postpartum sudden heatstroke with Huoluan vomiting and diarrhea is generally considered incurable. However, some can be saved with medication. Crucially, avoid Xiang Ru. Use Xiao Shu Huo Chan Dan (Clearing Heat Rescuing Birth Pill): Ren Shen (Ginseng Root) one liang, Dang Gui (Angelica Sinensis Root) two liang, Chuan Xiong (Ligusticum Rhizome) one liang, Rou Gui (Cinnamon Bark) two qian, Qing Hao (Artemisia Annua Herb) one qian. Decoct in water and take orally. Cured after one dose. Postpartum women only need blood and Qi tonification; once blood and Qi return, summer-heat dissipates naturally. Moreover, the formula contains cold-dispelling and heat-resolving ingredients, achieving unique efficacy. Some may question: since heatstroke is heat, why use Rou Gui (Cinnamon Bark)? Postpartum women suffer severe blood and Qi deficiency and are cold throughout the body. Upon feeling summer-heat, there is conflict, but not deep penetration of intense heat. It is merely slight summer-heat clashing with inherent cold, causing Huoluan. Here, Rou Gui warms deficiency-cold, and Qing Hao resolves mild summer-heat. Used within a large dose of blood and Qi tonics, it is controlled and prevents chaos. This is the brilliance of the prescription and its miraculous achievement. Why doubt it?
In summer, when heat is scorching, humans contracting summer-evil with sudden vomiting, diarrhea, and immediate death face the most terrifying condition. Do not lightly use Xiang Ru Yin (Elsholtia Decoction), nor recklessly use Baihu Tang (White Tiger Decoction). I have a formula named Re Xiao Shu San (Heat-Resolving Summer-heat Powder). Qing Hao (Artemisia Annua Herb) one liang, Ge Gen (Kudzu Root) one qian, Xiang Ru (Elsholtzia Herb) one qian, Fu Ling (Poria) one liang, Bai Zhu (Atractylodes Macrocephala Rhizome) three qian, Bai Bian Dou (Hyacinth Bean) two qian, Chen Pi (Citrus Reticulata Peel) one qian. Treatment brings peace. The formula's brilliance lies in using Qing Hao and Fu Ling as sovereign herbs. Qing Hao best resolves summer-heat and clears heat, serving dual purposes: guiding summer-heat entirely out through the Bladder. Ge Gen and Xiang Ru merely assist Qing Hao in dispelling summer-heat. Especially brilliant is the minimal use of Bai Zhu to strengthen Spleen and Stomach Qi, ensuring summer-heat retreats without damaging Stomach Qi. This far surpasses Xiang Ru Yin.
