行役负贩，驰驱于烈日之下，感触暑气，一时猝倒，人以为中暑也，谁知是中
乎。夫 者热之谓也，暑亦热也，何以分之？盖暑之热由外而入， 之热由内而
出。行役负贩者，驰驱劳苦，内热欲出，而外暑遏抑，故一时猝倒，是暑在外而热
闭之也。倘止治暑而不宣扬内热之气，则气闭于内，而热反不散矣。治法宜散其内
热，而佐之以消暑之味。方用救 丹∶
青蒿（五钱） 茯神（三钱） 白术（三钱） 香薷（一钱） 知母（一钱） 干葛（一钱）
甘草（五分） 水煎服。
一剂气通，二剂热散，不必三剂。
此方用青蒿平胃中之火，又解暑热之气，故以之为君。香薷解暑，干葛散热，
故以之为佐。又虑内热之极，但散而不寒，则火恐炎上，故加知母以凉之，用白术、
茯苓利腰脐而通膀胱，使火热之气俱从下而趋于小肠以尽出也。火既下行，自然不
逆而上冲，而外暑、内热各消化于乌有矣。
此症用解暑散亦效。
香薷 茯苓（各三钱） 甘草 黄连（各一钱） 白术（一两） 白扁豆（二钱） 白豆蔻（一粒）
水煎服。一剂即愈。
膏粱子弟，多食瓜果，以寒其胃，忽感暑气，一时猝倒，是中暑也。盖膏粱之
人，天禀原弱，又加多欲，未有不内寒者也。复加之瓜果，以增其寒凉，内寒之极，
外热反易于深入。阴虚之人，暑气即乘其虚而入之。治法不可祛暑为先，必须补气
为主。然既因阴虚，以至阳邪之中，似宜补阴为主。不知阳邪之入脾，根据阴气也。
补阴则阴气虽旺，转为阳邪之所喜，阳得阴而相合，正恐阴弱不能相配，若一旦助
其阴气，无论阴难却阳，而阳邪且久居之而生变矣。惟补其阳气，则阳气健旺，益
之散暑之味，则邪阳不敢与正阳相敌，必不战而自走也。方用∶
人参（五钱） 茯神（五钱） 白术（五钱） 香薷（二钱） 白扁豆（二钱） 陈皮（五分）
甘草（一钱） 水煎服。一剂气回，二剂暑尽散。
此方名为散暑回阳汤，方中参、苓、术、豆俱是健脾补气之药，以回其阳。用
香薷一味，以散其暑。何多少轻重之悬殊乎？不知阴虚者，脾阴之虚也。脾虽属阴，
非补阳之药不能效。况阳邪甚盛，非多用何以相敌乎。倘少少用之，恐有败衄难遏
之虞，即或取胜，暑退而元气未能骤复。与其暑去而后补阳，何若于邪旺之日，而
多用之，正既无亏，而邪又去速之为益哉。
此症用加味四君汤亦效。
人参 白术（各五钱） 甘草 香薷（各一钱） 茯苓（三钱） 炮姜（三分） 水煎服。二剂愈。
中暑气不能升降，霍乱吐泻，角弓反张，寒热交作，心胸烦闷，人以为暑气之
内热也，谁知是阴阳之拂乱乎。人身阴阳之气和，则邪不能相干。苟阴阳不能相交，
而邪即乘其虚而入之矣。且邪之入人脏腑也，助强而不助弱，见阴之强而即助阴，
见阳之强而即助阳，夏令之人多阴虚阳旺，邪乘阴虚而入，本欺阴之弱也。然见阳
气之旺又助阳而不助阴。阴见邪之助阳也，又妒阳之旺而相战，阳又嫌邪之党阳也，
欲嫁其邪于阴，而阴又不受，于是阴阳反乱，气不相通，上不能升，下不能降，霍
乱吐泻拂于中，角弓反张困于外，阴不交于阳而作寒，阳不交于阴而作热。心胸之
内竟成战场之地，安得而不烦闷哉。然则治法和其阴阳之气，而少佐之以祛暑之剂，
缓以调之，不必骤以折之也。方用和合阴阳汤∶
人参（一钱） 白术（二钱） 茯苓（五钱） 香薷（一钱） 藿香（一钱） 苏叶（一钱）
浓朴（五分） 陈皮（三分） 枳壳（三分） 砂仁（一粒） 天花粉（一钱） 水煎探冷，徐徐服之。
一剂阴阳和，二剂各
症愈，不必三剂。
此方分阴阳之清浊，通上下之浮沉，调和于拂逆之时，实有奇功，以其助正而
不增火，祛邪而不伤气，化有事为无事也。
此症用加减六君汤亦效。
人参 茯苓 白芍（各三钱） 白术（一两） 香薷（一钱） 砂仁（一粒） 陈皮（五分） 半夏（一钱）
水煎服。一剂即平。
中暑热之气，腹中疼痛，欲吐不能，欲泻不得，此名为干霍乱也。夫邪入胃中，
得吐则邪越于上，邪入腹中，得泻则邪趋于下矣。邪越于上，则邪不入于中，邪趋
于下，则邪不留于内。今不吐不泻，则邪不上不下，坚居于中焦。譬如贼人反叛，
虽四境安宁，而一时生变喋血于城门，横尸于内地，斯时非奋罔顾身之将，号召
忠勇，冒矢石而夺门靖难，乌能安反侧于顷刻，定祸患于须臾哉。治法急用∶
人参（一两） 瓜蒂（七个） 水煎一大碗。饮之即吐，而愈矣。
此方名为人参瓜蒂散。此等之病，脉必沉伏，不吐则死，古人亦知用瓜蒂吐之，
但不敢加入人参耳。盖此症原因，胃气之虚，以致暑邪之入，今加大吐则胃必更伤，
非用人参则不能于吐中而安其胃气也。且胃气素虚，而暑邪壅遏，虽用瓜蒂以吐之，
而气怯不能上送，往往有欲吐而不肯吐者，即或动吐，而吐亦不多，则邪何能遽出
乎。惟用人参至一两之多，则阳气大旺，力能祛邪而上涌。况得瓜蒂以助之，安得
而不大吐哉。邪因吐而遽散，而正气又复无伤。譬如内乱一定而民安物阜，仍是敉
宁之日，何至动四郊之多垒哉。
此症用参芦汤亦佳。
人参芦（二两） 煎滚汤（一碗，和之井水一碗，少入盐和匀饮之，以鹅翎扫喉，引其呕吐，
吐出即安，然不吐而能受，亦愈也。）
中暑热极发狂，登高而呼，弃衣而走，见水而投，人以为暑毒之侵，谁知胃火
之相助乎。夫暑热之入人脏腑也，多犯心而不犯胃。盖暑与心俱属火也，胃则心之
子也，胃见暑邪之犯心，即发其土中之火以相卫。胃乃多气多血之府，火不发则已，
发则其酷烈之威，每不可当。暑邪畏胃火之强，益遁入于心，而心又喜寒不喜热，
畏暑邪之直入，不敢自安，胃火怒，暑邪之直入于心中而不出，乃纵其火，以焚烧
于心之外，心又安禁二火之相逼乎？势必下堂而走，心君一出，而神无所根据，于是
随火炽而飞越。登高而呼者，火腾于上以呼救援也；弃衣而走者，憎衣之添热也；
见水而投者，喜水之克火也。此时心中无津液之养，皮肤之外，必多汗出亡阳，是
阴阳两竭之病，至危至急之候。苟不大泻其火，则燎原之焰，何以扑灭乎。方用三
圣汤∶
人参（三两） 石膏（三两） 玄参（三两） 水煎数碗，灌之，一剂狂定，二剂神安，不可
用三剂也。另用缓图汤∶
玄参（二两） 人参（一两） 麦冬（一两） 青蒿（一两） 水煎服。二剂而暑热两解矣。
三圣汤用石膏至三两，用人参、玄参各至三两，未免少有霸气。然火热之极，
非杯水可息，苟不重用，则烁干肾水立成乌烬。方中石膏虽多，而人参之分两与之
相同，实足以驱驾其白虎之威，故但能泻胃中之火，而断不至伤胃中之气。玄参又
能滋润生水，水生而火尤易灭也。至于缓图汤不用石膏者，以胃中之火既已大泻，
所存者不过余烟断焰，时起时灭，何必再用阴风大雨以洗濯之？故又改用麦冬、青
蒿既益其阴，又息其火，使细雨绸缪之为得也。或问∶因暑发狂，似宜消暑，乃三
圣汤但泻火而罔顾暑，何以能奏功耶？不知暑亦火也，泻火即泻暑矣。使泻火之中
加入香薷、藿香清暑之药，则石膏欲下降，而香薷、藿香又欲外散，转足以掣石膏
之手，反不能直泻其火矣。
此症用三清汤救之亦神。
玄参（四两） 石膏（一两） 青蒿（一两） 水煎服。一剂即安。
中暑热症自必多汗，今有大汗如雨，一出而不能止者，人以为发汗亡阳必死之
症也，谁知是发汗亡阴之死症乎。夫暑热伤心，汗自外泄，然而心中无汗也，何以
有汗？此汗乃生于肾，而非生于心也。盖心中之液，肾生之也，岂心之汗非肾之所
出乎。虽汗出亡阳，乃阳旺而非阴虚。但阴不能制阳，而阳始旺；亦阴不能摄阳，
而阳始亡。顾阴阳原两相根也，阴不能摄阳，而阳能恋阴，则阳尚可回于阴之中，
而无如其阳一出而不返也。阴根于阳，见阳之出而不留，亦且随之俱出，罄其肾中
之精，尽化为汗而大泄，试思心中之液几何，竟能发如雨之汗乎？明是肾之汗而非
心之汗也。汗既是肾而非心，则亡亦是阴而非阳矣。然则听其亡阴而死乎，尚有救
死之法在。方用救亡生阴丹∶
人参（二两） 熟地（四两） 山茱萸（二两） 北五味（五钱） 茯神（一两） 白芍（一两）
水煎服。
此方熟地、山萸、五味子均是填精补水之味，茯神安其心，白芍收其魂，人参
回其阳，此人之所知也。阴已外亡，非填其精髓，何以灌注涸竭之阴；阳已外亡，
非补其关元，何以招其散失之阳。山茱、五味补阴之中，仍是收敛之剂，阴得补而
水生，则肾中有本；汗得补而液转，则心内无伤。又得茯神以安之，白芍以收之，
则阳回阴返，自有神捷之机也。
此症用人参青蒿汤亦神。
人参（二两） 生地 麦冬（各一两） 青蒿（五钱） 北五味子（一钱） 水煎服。汗止即生，
否则无救。
中暑热极，妄见妄言，宛如见鬼，然人又安静不生烦躁，口不甚渴，此是寒极
相战，寒引神出，有似于狂，而非热极发狂也。夫中暑明是热症，何以热能变寒而
有似狂之症也？盖其人阴气素虚，阳气又复不旺，暑热之邪乘其阴阳两衰，由肺以
入心。而心气不足，神实时越出以遁于肾，而肾中阴寒之气上升，则暑自出于心之
外，流连于肺经之内矣。暑邪既已退出于心外，而心君尚恐暑邪之来侵，乃根据其肝木
之母以安神。心神入于肝则肝魂不宁，乃游出于躯壳之外，因而妄见鬼神，而妄言
诡异也。魂既外游，而神居魂室，反得享其宁静之福。况肝木原无火旺，而肾中阴
寒之气，相逼心君，正借以杜暑邪之侵，且恃之无恐，何生烦躁乎？惟是肺气独受
暑邪，火刑金而作渴，然肾见肺母之被刑，乃阴寒之气直冲而上以救肺，故口虽渴
而不甚也。然则治法奈何？散肺中之暑邪，补脾胃之土气；土气一旺而肺气亦旺矣。
肺旺可以敌邪，又得散邪之药，自然暑气难留，暑散而魂归神返，必至之势也。方
用护金汤∶
麦冬（一两） 人参（三钱） 百合（五钱） 茯苓（三钱） 紫菀（一钱） 香薷（一钱）
甘草（一钱） 水煎服。
二剂即愈。
此方但补肺脾胃之气，不去救心以益寒，不去助肾以泻火，不去补肝以逐神，
而魂自归肝，神自返心者，以邪有所制，何必逐邪之太甚，正未大虚，何必补正之
太多。不可因邪居于上而下治，正轻于下而重治也。
此症用人参麦冬汤亦妙。
人参（二两） 麦冬（三两） 水煎服。
中暑热，吐血倾盆，纯是紫黑之色，气喘作胀，不能卧倒，口渴饮水，又复不
快，人以为暑热之极而动血也，谁知是肾热之极而呕血乎。夫明是中暑以动吐血，
反属之肾热者？盖暑火以引动肾火也。夫肾中之火，龙雷之火也。龙雷原伏于地，
夏月则地下甚寒，龙雷不能下藏而多上泄，其怒气所激，而成霹雳之猛，火光划天，
大雨如注，往往然也。人身亦有龙雷之火，下伏于肾，其气每与天之龙雷相应。暑
气者，亦天之龙雷火也。暑热之极，而龙雷乃从地出，非同气相引之明验乎。人身
龙雷之火不动，则暑气不能相引。苟肾水原亏，肾火先跃跃欲动，一遇天之龙火，
同气相感，安得不勃然振兴哉。既已勃然振兴，而两火相激，其势更烈，乃直冲而
上，挟胃中所有之血而大吐矣。胃血宜红，而色变紫黑者，正显其龙雷之气也。凡
龙雷所劈之处，树木必变紫黑之色，所过脏腑何独不然。其所过之胃气，必然大伤，
气伤则逆，气逆则喘。胃气既伤，何能遽生新血以养胃乎，此胸胁之所以作胀也。
胃为肾之关门，关门不闭，夜无开阖之权，安能卧哉。血吐则液干，液干则口渴，
内水不足，必索外水以救焚，乃饮之水而不快，以龙雷之火乃阴火而非阳火也。治
法宜大补其肾中之水，以制龙雷之火，不可大泻其龙雷之火，以伤其胃中之气也。
方用沛霖膏∶
玄参（二两） 人参（一两） 生地（二两） 麦冬（二两） 牛膝（五钱） 荆芥（炒黑，三钱）
水煎服。一
剂血止，二剂喘胀消，三剂口亦不渴，四剂全愈。愈后仍服六味地黄丸可也。
此方大补肾水，水足而龙雷之火自归于肾之宅。火既安于肾宅，血自止于胃关，
何必用黄柏、知母以泻火，用香薷、藿香以散暑哉。况泻火而火愈炽，必至伤损夫
胃土，散暑而暑难退，必至消耗夫肺金，势必血不可止，火不可灭，而死矣。
此症用丹蒿汤亦神。
丹皮（三两） 荆芥（三钱） 青蒿（一两） 水煎服。
中暑热之气，两足冰冷，上身火热，烦躁不安，饮水则吐，人以为下寒上热之
症，乃暑气之阻隔阴阳也，谁知是暑散而肾火不能下归之故乎。人身龙雷之火，因
Travelers and peddlers, galloping under the scorching sun, contract summer-heat qi (Summer-heat Qi), and suddenly collapse. People think it is heatstroke (Heatstroke), but who knows it is Zhong Ye (Heat Closure). "Ye" refers to heat, and summer-heat is also heat; why distinguish them? The heat of summer-heat enters from the outside, whereas the heat of Ye emanates from the inside. Travelers and peddlers endure hard labor and travel, causing internal heat to want to escape, while external summer-heat suppresses it. Thus, they suddenly collapse because summer-heat is on the outside and internal heat is closed off. If one treats only the summer-heat without promoting the release of internal heat, the qi will remain closed inside, and the heat will not dissipate. The treatment method should be to disperse the internal heat and assist with flavors that relieve summer-heat. Use the formula Jiu Ye Dan (Rescue Ye Decoction):
Qing Hao (Artemisiae Annuae Herba, 5 qian) Fu Shen (Poria with Hostwood, 3 qian) Bai Zhu (Atractylodis Macrocephalae Rhizoma, 3 qian) Xiang Ru (Moslae Herba, 1 qian) Zhi Mu (Anemarrhenae Rhizoma, 1 qian) Gan Ge (Puerariae Radix, 1 qian)
Gan Cao (Glycyrrhizae Radix et Rhizoma, 5 fen) Decoct in water and take orally.
After one dose, qi flows freely; after two doses, heat dissipates; a third dose is unnecessary.
This formula uses Qing Hao to calm the fire in the stomach and resolve summer-heat qi, hence serving as the Sovereign herb. Xiang Ru resolves summer-heat, and Gan Ge disperses heat, hence serving as Assistant herbs. Furthermore, fearing that extreme internal heat, if only dispersed without cooling, might flare upwards, Zhi Mu is added to cool it. Bai Zhu and Fu Ling are used to benefit the waist and umbilicus and unblock the Bladder, ensuring that the qi of fire and heat all flow downwards towards the Small Intestine to exit completely. Since the fire moves downwards, it naturally does not rebel and rush upwards, and both external summer-heat and internal heat dissolve into nothingness.
For this condition, Jie Shu San (Relieve Summer-heat Powder) is also effective.
Xiang Ru Moshi (Folium Perillae, 3 qian each) Gan Cao Huang Lian (Coptidis Rhizoma, 1 qian each) Bai Zhu (1 liang) Bai Bian Dou (Dolichoris Semen, 2 qian) Bai Dou Kou (Amomi Fructus Rotundus, 1 grain)
Decoct in water and take orally. One dose leads to recovery.
Young men from wealthy families often eat melons and fruits to chill their stomachs. Suddenly contracting summer-heat qi, they collapse suddenly; this is true heatstroke. Generally, people from wealthy backgrounds have originally weak constitutions, and with excessive desires, they inevitably develop internal cold. Adding melons and fruits increases this coldness. When internal cold reaches its extreme, external heat easily penetrates deeply. In individuals with Yin deficiency, summer-heat qi takes advantage of the deficiency to enter. The treatment should not prioritize dispelling summer-heat but must focus on tonifying Qi. However, since it is due to Yin deficiency leading to invasion by Yang pathogenic factors, one might think tonifying Yin is primary. It is unknown that when Yang pathogenic factors enter the Spleen, they rely on Yin qi. Tonifying Yin makes Yin qi prosperous, which becomes favorable for Yang pathogenic factors; Yang combines with Yin. There is fear that if Yin is weak, it cannot match Yang, but if one aids Yin qi, regardless of whether Yin can repel Yang, the Yang pathogen will dwell there for a long time and cause changes. Only by tonifying Yang qi, making it robust, and adding flavors that disperse summer-heat, will the pathogenic Yang dare not oppose the healthy Yang, retreating without battle. Use the formula:
Ren Shen (Ginseng Radix, 5 qian) Fu Shen (5 qian) Bai Zhu (5 qian) Xiang Ru (2 qian) Bai Bian Dou (2 qian) Chen Pi (Citri Reticulatae Pericarpium, 5 fen)
Gan Cao (1 qian) Decoct in water and take orally. After one dose, qi returns; after two doses, summer-heat fully dissipates.
This formula is named San Shu Hui Yang Tang (Disperse Summer-heat and Restore Yang Decoction). Ren Shen, Fu Ling, Bai Zhu, and Bai Bian Dou in the formula are all herbs that strengthen the Spleen and tonify Qi to restore Yang. Xiang Ru is used to disperse summer-heat. Why such disparity in dosage and weight? It is unknown that Yin deficiency here refers to Spleen Yin deficiency. Although the Spleen belongs to Yin, it requires Yang-tonifying herbs to be effective. Moreover, with very strong Yang pathogens, large dosages are needed to counteract them. If small amounts are used, there is a risk of defeat that cannot be contained. Even if victory is achieved, after summer-heat recedes, Yuan Qi (Primal Qi) may not recover rapidly. Rather than tonifying Yang after summer-heat leaves, is it not more beneficial to use larger amounts during the peak of the pathogen, so that Zheng Qi (Healthy Qi) remains intact and the pathogen is removed quickly?
For this condition, Jia Wei Si Jun Tang (Modified Four Gentlemen Decoction) is also effective.
Ren Shen Bai Zhu (each 5 qian) Gan Cao Xiang Ru (each 1 qian) Fu Ling (3 qian) Pao Jiang (Prepared Zingiberis Rhizoma, 3 fen) Decoct in water and take orally. Two doses lead to recovery.
In heatstroke, Qi fails to ascend and descend, resulting in Huo Luan (Cholera-like syndrome with vomiting and diarrhea), opisthotonos (Angle Bow Reverse Stretching), alternating chills and fever, and chest/heart distress. People think it is internal heat from summer-heat, but who knows it is a disorder of Yin and Yang? When the Yin and Yang Qi of the human body are harmonious, pathogens cannot interfere. If Yin and Yang cannot interact, pathogens take advantage of the deficiency to enter. When pathogens enter the Zang-Fu organs, they aid the strong and do not aid the weak. Seeing strong Yin, they aid Yin; seeing strong Yang, they aid Yang. In summer, people often have Yin deficiency and Yang excess. Pathogens enter due to Yin deficiency, bullying the weakness of Yin. However, seeing strong Yang, they aid Yang rather than Yin. Seeing the pathogen aiding Yang, Yin becomes jealous of Yang's prosperity and fights. Yang dislikes the pathogen siding with Yang and tries to blame the pathogen on Yin, but Yin refuses. Thus, Yin and Yang become chaotic, Qi does not communicate, ascending fails above, descending fails below. Huo Luan vomiting and diarrhea block the middle, opisthotonos troubles the exterior. Yin not interacting with Yang causes cold; Yang not interacting with Yin causes heat. The interior of the heart and chest becomes a battlefield, how can one not feel distressed? Therefore, the treatment method should harmonize Yin and Yang Qi, slightly assist with anti-summer-heat agents, and regulate slowly, without abrupt suppression. Use the formula He He Yin Yang Tang (Harmonize Yin and Yang Decoction):
Ren Shen (1 qian) Bai Zhu (2 qian) Fu Ling (5 qian) Xiang Ru (1 qian) Huo Xiang (Patchouliae Herba, 1 qian) Su Ye (Perillae Folium, 1 qian)
Nong Po (Magnoliae Officinalis Cortex, 5 fen) Chen Pi (3 fen) Zhi Qiao (Aurantii Fructus Immaturus, 3 fen) Sha Ren (Amomi Fructus, 1 grain) Tian Hua Fen (Trichosanthis Radix, 1 qian) Decoct in water, let cool, and take slowly.
After one dose, Yin and Yang harmonize; after two doses, all symptoms resolve; a third dose is unnecessary.
This formula separates the clear and turbid aspects of Yin and Yang, connects the floating and sinking of upper and lower, and harmonizes during times of rebellion, achieving miraculous results. It assists Healthy Qi without increasing Fire, expels Pathogens without damaging Qi, and turns events into non-events.
For this condition, Jia Jian Liu Jun Tang (Modified Six Gentlemen Decoction) is also effective.
Ren Shen Fu Ling Bai Shao (Paeoniae Radix Alba, each 3 qian) Bai Zhu (1 liang) Xiang Ru (1 qian) Sha Ren (1 grain) Chen Pi (5 fen) Ban Xia (Pinelliae Rhizoma, 1 qian)
Decoct in water and take orally. One dose brings stability.
Contracting summer-heat Qi, abdominal pain occurs, desire to vomit but unable, desire to defecate but unable; this is named Gan Huo Luan (Dry Cholera). When pathogens enter the Stomach, vomiting expels pathogens upwards; when pathogens enter the abdomen, defecation directs pathogens downwards. If pathogens go up, they do not enter the middle; if pathogens go down, they do not stay inside. Now, without vomiting or defecation, pathogens neither go up nor down, firmly residing in the Middle Jiao. It is like rebels revolting; although the four borders are peaceful, sudden bloodshed occurs at the city gate, and corpses lie in the interior. At this time, unless a general who disregards his life rallies loyal and brave troops,冒着 arrows and stones to seize the gate and quell the disaster, how can one pacify the rebels in an instant and settle the trouble in a moment? The treatment method urgently requires:
Ren Shen (1 liang) Gua Di (Momordicae Fructus, 7 pieces) Decoct in a large bowl of water. Drinking it induces vomiting, and recovery follows.
This formula is named Ren Shen Gua Di San (Ginseng and Momordica Powder). For such diseases, the pulse must be deep and hidden; without vomiting, death ensues. Ancients knew to use Gua Di to induce vomiting but dared not add Ren Shen. The cause of this condition is deficiency of Stomach Qi, allowing summer-heat pathogens to enter. Now, inducing heavy vomiting would further damage the Stomach; without Ren Shen, Stomach Qi cannot be stabilized during vomiting. Moreover, since Stomach Qi is inherently weak and summer-heat pathogens are obstructed, even using Gua Di to induce vomiting, the Qi is timid and cannot send upwards. Often, there is a desire to vomit but inability to do so. Even if vomiting is triggered, the amount is small, so how can pathogens exit quickly? Only by using Ren Shen up to one liang, Yang Qi becomes vigorous, possessing the strength to expel pathogens and surge upwards. With the assistance of Gua Di, how could one not vomit heavily? Pathogens scatter rapidly due to vomiting, and Healthy Qi remains undamaged. It is like internal chaos settled and people living in peace; why disturb the ramparts of the suburbs?
For this condition, Shen Lu Tang (Ginseng Stem Decoction) is also good.
Ren Shen Lu (Ginseng Radix Caulis, 2 liang) Decoct in boiling water (one bowl), mix with well water (one bowl), add a little salt, and drink evenly. Sweep the throat with a goose feather to induce vomiting. Vomiting brings relief. If vomiting does not occur but intake is tolerated, recovery also ensues.
Extreme summer-heat causes madness: climbing high and shouting, discarding clothes and running, jumping into water upon seeing it. People think it is invasion by summer-heat toxin, but who knows it is assisted by Stomach Fire? Summer-heat entering the Zang-Fu organs mostly attacks the Heart, not the Stomach. Summer-heat and Heart both belong to Fire. The Stomach is the son of the Heart. Seeing the Heart attacked by summer-heat pathogens, the Stomach emits Fire from within Earth to defend. The Stomach is a mansion of abundant Qi and Blood. If Fire does not erupt, fine; but once it erupts, its fierce power is often irresistible. Fearing the strength of Stomach Fire, summer-heat pathogens retreat into the Heart. The Heart prefers cold and dislikes heat, fearing direct invasion by summer-heat, feeling insecure. Stomach Fire rages, summer-heat pathogens invade the Heart directly and cannot exit. Thus, Fire is unleashed, burning outside the Heart. How can the Heart withstand the pressure of two Fires? It must flee downstairs. Once the Heart Monarch exits, Shen (Spirit) has no foundation, flying away with the blazing fire. Climbing high and shouting is Fire rising upwards calling for help; discarding clothes and running is hating clothes for adding heat; jumping into water is liking Water to overcome Fire. At this time, the Heart lacks fluid nourishment, and sweat escapes profusely from the skin, losing Yang. This is a disease of exhaustion of both Yin and Yang, a critical and urgent state. If Fire is not greatly purged, how can the prairie fire be extinguished? Use the formula San Sheng Tang (Three Sages Decoction):
Ren Shen (3 liang) Shi Gao (Gypsum Fibrosum, 3 liang) Xuan Shen (Scrophulariae Radix, 3 liang) Decoct several bowls of water, administer orally. After one dose, madness settles; after two doses, Spirit calms. Do not use a third dose. Additionally, use Huan Tu Tang (Slow Plan Decoction):
Xuan Shen (2 liang) Ren Shen (1 liang) Mai Dong (Ophiopogonis Radix, 1 liang) Qing Hao (1 liang) Decoct in water and take orally. After two doses, summer-heat and heat are both resolved.
San Sheng Tang uses Shi Gao up to 3 liang, and Ren Shen, Xuan Shen each up to 3 liang, which may seem somewhat domineering. However, extreme fire cannot be extinguished by a cup of water. Without heavy usage, Kidney Water will be scorched dry instantly. Although Shi Gao is used in large quantities, the amount of Ren Shen is equal, truly sufficient to control the majesty of Bai Hu Tang (White Tiger Decoction). Thus, it purges Stomach Fire without damaging Stomach Qi. Xuan Shen moistens and generates Water; when Water is generated, Fire is easier to extinguish. Huan Tu Tang does not use Shi Gao because Stomach Fire has already been greatly purged; what remains is just lingering smoke and dying flames, appearing and disappearing. Why use heavy Yin wind and rain to wash it again? Thus, Mai Dong and Qing Hao are changed to both benefit Yin and extinguish Fire, achieving the effect of gentle rain. Someone asks: Madness caused by summer-heat seems suitable for relieving summer-heat, yet San Sheng Tang only purges Fire and ignores summer-heat; how can it work? It is unknown that summer-heat is also Fire; purging Fire is purging summer-heat. If Xiang Ru and Huo Xiang (herbs clearing summer-heat) were added to purging Fire, Shi Gao would want to descend, while Xiang Ru and Huo Xiang would want to disperse externally, interfering with Shi Gao's action, preventing direct purging of Fire.
For this condition, San Qing Tang (Three Clears Decoction) is also miraculous.
Xuan Shen (4 liang) Shi Gao (1 liang) Qing Hao (1 liang) Decoct in water and take orally. One dose brings peace.
Heatstroke naturally involves much sweating. Now, there is heavy sweating like rain, continuous and unstoppable. People think it is sweating leading to Yang loss, a fatal symptom, but who knows it is sweating leading to Yin loss, a fatal symptom? Summer-heat damages the Heart, and sweat leaks outwards, yet the Heart itself does not sweat. How can there be sweat? This sweat is generated in the Kidney, not the Heart. The fluids of the Heart are generated by the Kidney. Is Heart sweat not from the Kidney? Although sweating leads to Yang loss, it is due to Yang excess, not Yin deficiency. It is merely that Yin cannot control Yang, so Yang becomes excessive; Yin cannot secure Yang, so Yang escapes. Yin and Yang are mutually rooted. If Yin cannot secure Yang, but Yang can cling to Yin, Yang might return to Yin. Unfortunately, Yang goes out and does not return. Yin roots in Yang; seeing Yang leave and not stay, Yin follows and exits together, exhausting the essence in the Kidney, turning entirely into sweat and leaking heavily. Consider how much fluid is in the Heart; how can it produce rain-like sweat? Clearly, it is Kidney sweat, not Heart sweat. Since sweat is from the Kidney and not the Heart, loss is also Yin loss, not Yang loss. Then, should one let Yin loss lead to death? There is still a method to save life. Use the formula Jiu Wang Sheng Yin Dan (Save Life and Generate Yin Pill):
Ren Shen (2 liang) Shu Di (Rehmanniae Radix Preparata, 4 liang) Shan Zhu Yu (Corni Fructus, 2 liang) Bei Wu Wei (Schisandrae Fructus, 5 qian) Fu Shen (1 liang) Bai Shao (1 liang)
Decoct in water and take orally.
In this formula, Shu Di, Shan Zhu Yu, and Wu Wei Zi are all substances that fill essence and replenish water. Fu Shen calms the Heart, Bai Shao gathers the Hun (Ethereal Soul), and Ren Shen restores Yang; this is known to people. Since Yin has escaped externally, how else to irrigate depleted Yin but by filling essence and marrow? Since Yang has escaped externally, how else to attract scattered Yang but by tonifying Guan Yuan (CV4)? Shan Zhu Yu and Wu Wei Zi, while tonifying Yin, are also astringents. Yin benefits from tonification, Water generates, giving the Kidney a root; sweat benefits from tonification, fluids turn, leaving the Heart unharmed. With Fu Shen to calm it and Bai Shao to gather it, Yang returns and Yin reverses, having a swift divine opportunity.
For this condition, Ren Shen Qing Hao Tang (Ginseng and Artemisia Decoction) is also miraculous.
Ren Shen (2 liang) Sheng Di (Rehmanniae Radix, 1 liang) Mai Dong (1 liang) Qing Hao (5 qian) Bei Wu Wei Zi (1 qian) Decoct in water and take orally. If sweating stops, life is saved; otherwise, there is no rescue.
Extreme summer-heat causes delusions and hallucinations, speaking wildly as if seeing ghosts, yet the person remains quiet without irritability, and thirst is not severe. This is extreme Cold battling, Cold drawing out the Shen, resembling madness, but it is not madness caused by extreme Heat. Heatstroke is clearly a Heat syndrome; how can Heat transform into Cold and present symptoms resembling madness? Generally, this person has inherent Yin deficiency and weak Yang. Summer-heat pathogens take advantage of dual deficiency of Yin and Yang, entering from the Lung to the Heart. With insufficient Heart Qi, Shen frequently escapes to the Kidney. The Yin-Cold Qi in the Kidney rises, so summer-heat exits the Heart and lingers in the Lung Meridian. Having retreated outside the Heart, the Heart Monarch fears invasion by summer-heat and relies on the Mother of Liver Wood to calm the Shen. When Shen enters the Liver, Liver Hun becomes restless, wandering outside the body, causing delusions of ghosts and strange speech. With Hun wandering outside, Shen resides in the Hun chamber, enjoying tranquility. Moreover, Liver Wood has no excessive Fire, and Kidney Yin-Cold Qi presses on the Heart Monarch, helping to prevent summer-heat invasion, instilling fearlessness, thus no irritability arises. Only the Lung Qi alone suffers from summer-heat; Fire punishes Metal causing thirst. However, seeing the Lung Mother punished, Kidney Yin-Cold Qi rushes up to save the Lung, so although thirsty, it is not severe. So, what is the treatment? Disperse summer-heat in the Lung, tonify Earth Qi of the Spleen and Stomach. When Earth Qi prospers, Lung Qi also prospers. Prosperous Lung Qi can resist pathogens; with dispersing herbs, summer-heat is hard to retain. Summer-heat disperses, Hun returns, Shen returns; this is inevitable. Use the formula Hu Jin Tang (Protect Metal Decoction):
Mai Dong (1 liang) Ren Shen (3 qian) Bai He (Lilii Bulbus, 5 qian) Fu Ling (3 qian) Zi Wan (Asteris Radix, 1 qian) Xiang Ru (1 qian)
Gan Cao (1 qian) Decoct in water and take orally.
Two doses lead to recovery.
This formula only tonifies Qi of the Lung, Spleen, and Stomach. It does not save the Heart to benefit Cold, does not assist the Kidney to purge Fire, does not tonify the Liver to drive out the Soul. Yet Hun returns to the Liver, and Shen returns to the Heart spontaneously, because the pathogen is controlled. Why drive the pathogen too severely? Zheng Qi is not greatly deficient, why tonify Zheng Qi too much? One should not treat downwards because the pathogen is above, nor treat heavily below where Zheng Qi is light.
For this condition, Ren Shen Mai Dong Tang (Ginseng and Ophiopogon Decoction) is also excellent.
Ren Shen (2 liang) Mai Dong (3 liang) Decoct in water and take orally.
Summer-heat causes hematemesis pouring like a basin, purely purple-black in color, asthma and distension, inability to lie down, thirst for drinking but discomfort afterwards. People think it is extreme summer-heat moving Blood, but who knows it is extreme Kidney Heat causing vomiting of blood? Clearly, it is heatstroke moving blood to vomit, yet attributed to Kidney Heat? Because summer-fire induces Kidney Fire. The Fire in the Kidney is Dragon-Thunder Fire. Dragon-Thunder originally hides underground. In summer, the underground is very cold, Dragon-Thunder cannot hide downwards and leaks upwards. Its anger激ates, forming fierce thunderbolts, lightning splitting the sky, heavy rain pouring; this is common. The human body also has Dragon-Thunder Fire, hiding in the Kidney, its Qi responding to Heaven's Dragon-Thunder. Summer-heat is also Heaven's Dragon-Thunder Fire. Extreme summer-heat causes Dragon-Thunder to emerge from the earth, a clear proof of similar energies attracting each other. If Dragon-Thunder Fire in the body does not move, summer-heat cannot attract it. If Kidney Water is originally deficient, Kidney Fire is ready to move; encountering Heaven's Dragon Fire, similar energies resonate, how can it not vigorously rise? Having risen vigorously, the two Fires clash, their momentum becoming fiercer, rushing upwards, carrying all blood in the Stomach to vomit heavily. Stomach blood should be red, but turning purple-black shows its Dragon-Thunder Qi. Wherever Dragon-Thunder strikes, trees turn purple-black; how much more so for viscera passed through? The Stomach Qi passed through is greatly damaged. Qi damage causes rebellion, Qi rebellion causes asthma. With damaged Stomach Qi, how can new blood be generated quickly to nourish the Stomach? This is why the chest and hypochondrium become distended. The Stomach is the Gate of the Kidney. If the Gate is not closed, lacking opening and closing authority at night, how can one lie down? Blood loss dries fluids, fluid dryness causes thirst. Insufficient internal water seeks external water to save from burning, but drinking water brings no comfort because Dragon-Thunder Fire is Yin Fire, not Yang Fire. The treatment should greatly tonify Water in the Kidney to restrain Dragon-Thunder Fire, not greatly purge Dragon-Thunder Fire to damage Stomach Qi. Use the formula Pei Lin Gao (Abundant Rain Paste):
Xuan Shen (2 liang) Ren Shen (1 liang) Sheng Di (2 liang) Mai Dong (2 liang) Niu Xi (Achyranthis Bidentatae Radix, 5 qian) Jing Jie (Schizonepetae Herba, stir-fried black, 3 qian)
Decoct in water and take orally. One dose stops bleeding, two doses resolve asthma and distension, three doses stop thirst, four doses achieve full recovery. After recovery, continuing to take Liu Wei Di Huang Wan (Six-Ingredient Pill with Rehmannia) is acceptable.
This formula greatly tonifies Kidney Water. When Water is sufficient, Dragon-Thunder Fire naturally returns to its residence in the Kidney. Once Fire is safe in the Kidney residence, blood stops at the Stomach Gate. Why use Huang Bo (Phellodendri Cortex) and Zhi Mu to purge Fire, or Xiang Ru and Huo Xiang to disperse summer-heat? Moreover, purging Fire makes Fire more intense, inevitably damaging Stomach Earth; dispersing summer-heat makes summer-heat hard to retreat, inevitably consuming Lung Metal. Ultimately, blood cannot stop, Fire cannot be extinguished, leading to death.
For this condition, Dan Hao Tang (Moutan and Artemisia Decoction) is also miraculous.
Dan Pi (Moutan Cortex, 3 liang) Jing Jie (3 qian) Qing Hao (1 liang) Decoct in water and take orally.
Summer-heat Qi causes cold feet, hot upper body, irritability, and vomiting upon drinking. People think it is a syndrome of Lower Cold and Upper Heat, blocked by summer-heat isolating Yin and Yang, but who knows it is because summer-heat disperses and Kidney Fire cannot descend? The Dragon-Thunder Fire in the human body, because
