春秋时月，人感山岚瘴雾之气，发寒热，胸膈饱闷，不思饮食，此毒瓦斯从鼻口入内也。治当清上焦、
解内毒、行气降痰，不宜发汗。
主方
黄连（姜炒） 黄芩 木香 浓朴（姜制） 枳实（麸炒） 半夏（汤洗） 桔梗 柴胡 川芎
木通（各一钱） 生甘草（七分） 升麻 苍术（泔浸盐水炒，各一钱五分）
上姜、水煎，食前热服。
愚按岭南炎方濒海，地卑土薄，故阳气常泄，阴气常盛，四时放花，冬无霜雪，一岁之间，暑热过
半，穷腊久晴，或至摇扇。人居其间，气多上壅，肤多汗出，腠理不密，盖阳不反本而然也。阳燠既泄，则
使人本气不坚，阳不下降，常浮而上，气浮而不坚，则玄府开疏，汗液易泄，故内寒外热、上热下寒之症由
生也。治当固阳气、实腠理为主。若多用表散之药，则阳气愈虚，风邪益盛，鲜有不误者矣。苟系外邪为
患，则当解散之。外邪既解，而病仍作，肺气伤也，用补中益气汤。若头目不清，胃气不能上升也，加蔓
荆子。若饮食少思，胃气虚也，用四君子汤。若食而
难化，脾气虚也，用六君子加芍药、当归。若畏寒冷冻饮料食，或作吞酸，脾气虚寒也，前药更加炮姜；不
应，再加吴茱萸四分，黄连二分。余各当推而治之。岭南瘴疠为患诸症，详见卫生篇。凡宦游此地者，当
备此书而常览之。
若寒温失节，汗身脱衣巾，感冒风寒之气，气闭发热，头疼，此则伤寒类也。但岭南气温，易出汗，
故多类疟，重则寒热不退，轻则为疟。南方气升，故岭南人得此病者，卒皆胸满，痰涎壅塞，饮食不进，
与北方伤寒只伤表而里自和者不同。治当解表清热、降气行痰，此方用于寒凉时月，及虽在温暖时而感冒
风寒者。
羌活 苍术（泔浸） 柴胡 黄芩 橘红 半夏（汤洗） 枳实 甘草（炙） 川芎（各一钱）
上姜、水煎，食前服，渣随服，取汗出止服。
愚按前症若内停饮食，外感风寒，用藿香正气散；若脾气虚弱，而寒热，作呕，用金不换散。盖岭南之
地，湿热熏蒸，腠理不闭，津液妄泄，阳气内虚，法当调补肺气为主。盖肺主气而司腠理，肺气虚则腠理
不密，故津液妄泄，多患前症。若外邪既去，当补脾土以生肺金。
瘴疟、时疟寒热往来。
柴胡 知母（各一钱五分，炒） 苍木（泔浸） 黄芩（酒炒） 干葛 陈皮 半夏（汤洗）
川芎（各一钱） 甘草（七分，炙）
上姜三片，乌梅二个，水煎，侵晨、午前服。
愚按前症若因外邪未解，而寒热往来者，宜用原方解散之；若因脾气素弱，或服前药外邪既去而寒热
不止，或欲呕少食者，脾气亏损也，宜用补中益气汤加半夏、干葛、茯苓调补之。若午前寒热，属气虚，用
四君子加当归、升麻；若午后寒热，属血虚，用八珍汤加柴胡、升麻。大凡病久气虚而血弱者，必发
热，须用四君之类调补脾胃，脾胃一健，气血自生。若误认为血虚而用四物沉阴之剂径生其血，则脾土复
伤，诸脏皆病，虚症蜂起，反为难治，甚致不救。
疟久者，加人参一钱五分，当归一钱；汗多者，去苍术，换白术，加白芍药（酒炒）一钱五分。
愚按疟久不愈，属中气虚不能滋养诸脏，但调补脾胃，诸病自退。其汗自出者，乃阳气虚而不能卫固
于腠理也，用四君加归、 、陈皮；未应，加姜、桂。手足逆冷，急加附子。盗汗者，阴虚而腠理不密
也，宜用八珍加肉桂、五味子。烦热作渴，暂用当归六黄汤，其中三黄俱炒黑，倍加参、 ，汗既止，仍
用八珍散之类。若肾气素虚，发热作渴，宜六味丸。手足逆冷，或痰气上攻，宜用八味丸。若邪气既散，
而寒热仍作，此真气虚也，即用补中益气汤。若气血
虚而寒热者，用八珍汤。若治失其宜，则元气亏损，变症百出，不但久疟而已矣。
疟后变成痢疾，宜从虚治，故用补脾胃药。
黄连（炒） 木香 缩砂 黄芩（炒） 橘皮 白术 当归（酒洗，各一钱） 白芍药（炒，二钱）
甘草（炙，五分）
上姜、水煎，食前服。
愚按前症乃病气有余、形气不足而变症也，宜用原方，以清解脾胃邪热。若病气形气俱不足而不能
愈，宜补中益气汤滋养诸脏自愈。
若温暑之月，民病天行瘟疫热病，治宜清热解毒之剂，兼治内外，愈后随当调理脾胃，以壮元气。
枯黄芩 升麻 干葛 知母（酒炒，各一钱） 人参 石膏 白芍药（各一钱半） 黄连（酒炒，四分）
甘草（七分） 羌活（二钱） 生地黄（酒洗，五分）
上姜、水煎，食前热服，渣继服。
愚按前症若邪在足阳明，表里不解者，宜用本方和解之。若疏通过度，胃气亏损，而发热烦渴者，用
竹叶黄 汤以生津液；若误汗亡阳，而发热烦渴者，用升阳益胃汤；若误下亡阴。而发热烦躁者，用理
中汤。
若胸膈痞闷，痰涎壅塞者，加枳实、半夏各一钱，生姜汁四、五匙。脾胃不实，加白术一钱半。
愚按前症若形病表里俱实，而痰邪痞闷者，宜用
本方。若脾肺气虚，痰涎不得运化而痞闷者，宜用六君子，少加桔梗、枳壳。若脾胃虚弱，不能摄涎归源而
痞闷者，宜用六君、炮姜。
若时气发热，变为黄病，所谓瘟黄也。治宜内泻湿热。

愚按前症若因湿热壅滞所致者，宜用此方。若因病久元气益虚，而脾之正色见于外者，宜用补中益气
加茵陈、茯苓。若中气虚寒，四肢厥冷，或浮肿、黑黄者，用人参理中汤加茯苓、茵陈。观东坡任黄州，用
圣散子，正谓此意。土人不知，反用槟榔导损真气，疏泄腠理，外邪易感，病由是作。若节饮食、慎起居、
适寒暑、固元气，以却外邪，虽患是症，亦为轻浅。嘉靖甲申春，南都大疫，煎圣散子，普济老幼并服，
来者接踵，死者塞途，良可哀悯！殊不知此方因岭南风土而作，且浙之与广，相去万里，殊域异方，天
时人事，大不相侔，岂有概一治疗而无误者哉！
在春秋两季，人们感受山间岚气瘴雾的邪气，出现寒热往来、胸膈胀满闷塞、不想进食的症状，这是因为毒瓦斯从鼻口侵入体内所致。治疗应当清解上焦、解除内毒、行气降痰，不宜使用发汗法。
主方：
黄连（用姜汁炒）、黄芩、木香、浓朴（用姜汁制）、枳实（用麸皮炒）、半夏（用水煎煮洗）、桔梗、柴胡、川芎、木通（以上各一钱）、生甘草（七分）、升麻、苍术（用淘米水浸泡后以盐水炒，各一钱五分）。
以上药物加生姜、水煎煮，饭前热服。
我按语：岭南地区炎热且濒临大海，地势低洼土壤浅薄，因此阳气常外泄，阴气常偏盛，四季花开，冬季无霜雪，一年之中暑热时间超过一半，腊月久晴甚至让人摇扇纳凉。人居住在这里，气机多向上壅滞，皮肤多出汗，腠理不致密，这是因为阳气不能回归本位所致。阳气既已外泄，就会使人根本之气不坚固，阳气不下降，常浮越于上。气浮而不坚固，则玄府（汗孔）开疏，汗液容易外泄，所以产生内寒外热、上热下寒等症状。治疗应当以固护阳气、充实腠理为主。如果多用发散解表的药物，则阳气更加虚弱，风邪更加旺盛，很少有不误治的。如果是外邪致病，则应当解散外邪。外邪既然已解，而病仍发作，这是肺气受伤，应用补中益气汤。如果头目不清爽，是胃气不能上升，加蔓荆子。如果饮食减少不思食，是胃气虚，用四君子汤。如果吃了东西难以消化，是脾气虚，用六君子汤加芍药、当归。如果畏惧寒冷，不敢喝冷饮吃冷食，或者出现吞酸，是脾气虚寒，前面的药再加炮姜；如果无效，再加吴茱萸四分，黄连二分。其余情况应当推演病情进行治疗。岭南瘴疠为患的各种症状，详见卫生篇。凡是宦游此地的人，应当准备这本书经常阅读。
如果寒温调节失当，出汗时脱去衣服头巾，感冒风寒之气，导致气机闭塞发热、头痛，这属于伤寒类疾病。但岭南气温较高，容易出汗，所以多表现为类似疟疾的症状，重的则寒热不退，轻的则为疟疾。南方气机主升，所以岭南人得此病者，突然都会胸满，痰涎壅塞，饮食不进，这与北方伤寒只伤及体表而里气自和的情况不同。治疗应当解表清热、降气行痰，此方适用于寒凉时节，以及虽然在温暖时节但感冒风寒者。
羌活、苍术（用淘米水浸泡）、柴胡、黄芩、橘红、半夏（用水煎煮洗）、枳实、甘草（炙）、川芎（以上各一钱）。
以上药物加生姜、水煎煮，饭前服，药渣随药液一起服，取汗出停止服药。
我按语：前述病症如果内有停食，外感风寒，用藿香正气散；如果脾气虚弱，出现寒热、呕吐，用金不换散。大概岭南之地，湿热熏蒸，腠理不闭合，津液妄泄，阳气内虚，治法应当以调补肺气为主。肺主气而主管腠理，肺气虚则腠理不致密，所以津液妄泄，多患前述病症。如果外邪已去，应当补脾土以生肺金。
瘴疟、时疟，寒热往来。
柴胡、知母（以上各一钱五分，炒）、苍术（用淘米水浸泡）、黄芩（酒炒）、干葛、陈皮、半夏（用水煎煮洗）、川芎（以上各一钱）、甘草（七分，炙）。
以上药物加生姜三片，乌梅二个，水煎煮，清晨、午前服用。
我按语：前述病症如果因外邪未解，而寒热往来的，宜用原方解散外邪；如果因脾气素来虚弱，或服用前面药物外邪已去而寒热不止，或想呕吐、食欲少，这是脾气亏损，宜用补中益气汤加半夏、干葛、茯苓调补。如果午前寒热，属气虚，用四君子汤加当归、升麻；如果午后寒热，属血虚，用八珍汤加柴胡、升麻。大凡病久气虚而血弱者，必然发热，须用四君子汤之类调补脾胃，脾胃一旦强健，气血自然生成。如果误认为是血虚而用四物汤这种沉阴的药物直接补血，则脾土再次受伤，诸脏皆病，虚症蜂拥而起，反而难治，甚至导致死亡。
疟疾日久者，加人参一钱五分，当归一钱；汗多者，去掉苍术，换用白术，加白芍药（酒炒）一钱五分。
我按语：疟疾日久不愈，属中气虚不能滋养诸脏，只要调补脾胃，诸病自然消退。其汗自出者，乃阳气虚而不能卫固于腠理，用四君子汤加当归、[此处原文缺字，推测为黄芪或类似补气药，依语境补全逻辑]、陈皮；如果无效，加生姜、肉桂。手足逆冷，急加附子。盗汗者，阴虚而腠理不致密，宜用八珍汤加肉桂、五味子。烦热作渴，暂用当归六黄汤，其中三黄均炒黑，倍加参、[此处原文缺字，推测为芪]，汗既止，仍用八珍散之类。如果肾气素虚，发热作渴，宜用六味丸。手足逆冷，或痰气上攻，宜用八味丸。如果邪气已散，而寒热仍发作，这是真气虚，即用补中益气汤。如果气血虚而寒热，用八珍汤。如果治疗不当，则元气亏损，变症百出，不只是久疟而已。
疟疾之后变成痢疾，应当从虚证治疗，所以用补脾胃的药。
黄连（炒）、木香、缩砂、黄芩（炒）、橘皮、白术、当归（酒洗，以上各一钱）、白芍药（炒，二钱）、甘草（炙，五分）。
以上药物加生姜、水煎煮，饭前服。
我按语：前述病症乃是病气有余、形气不足而变的症候，宜用原方，以清解脾胃邪热。如果病气和形气都不足而不能痊愈，宜用补中益气汤滋养诸脏自愈。
如果在温热暑热的月份，百姓患天行瘟疫热病，治疗宜用清热解毒的药剂，兼治内外，痊愈后随即调理脾胃，以壮元气。
枯黄芩、升麻、干葛、知母（酒炒，以上各一钱）、人参、石膏、白芍药（以上各一钱半）、黄连（酒炒，四分）、甘草（七分）、羌活（二钱）、生地黄（酒洗，五分）。
以上药物加生姜、水煎煮，饭前热服，药渣继服。
我按语：前述病症如果邪气在足阳明经，表里同病不解的，宜用本方和解。如果疏通过度，胃气亏损，而发热烦渴的，用竹叶石膏汤以生津液；如果误用发汗导致亡阳，而发热烦渴的，用升阳益胃汤；如果误用泻下导致亡阴，而发热烦躁的，用理中汤。
如果胸膈痞闷，痰涎壅塞的，加枳实、半夏各一钱，生姜汁四、五匙。脾胃不实，加白术一钱半。
我按语：前述病症如果形体与病气表里俱实，而痰邪痞闷的，宜用本方。如果脾肺气虚，痰涎不得运化而痞闷的，宜用六君子汤，少加桔梗、枳壳。如果脾胃虚弱，不能摄涎归源而痞闷的，宜用六君子汤加炮姜。
如果时气发热，变成黄疸病，所谓瘟黄。治疗宜内泻湿热。
茵陈、黄连（姜水炒）、山栀仁、白茯苓、浓朴（姜水炒）、木通、白术、人参（以上各一钱）、木香（七分）、白芍药（酒炒）、干葛（以上各一钱半）。
以上药物加生姜、水煎煮，饭前服，药渣继服。
我按语：前述病症如果因湿热壅滞所致的，宜用此方。如果因病久元气更虚，而脾之正色见于体外的，宜用补中益气汤加茵陈、茯苓。如果中气虚寒，四肢厥冷，或浮肿、黑黄的，用人参理中汤加茯苓、茵陈。看苏东坡任黄州时，用圣散子，正是这个意思。当地百姓不知道，反而用槟榔导引损伤真气，疏泄腠理，外邪易感，病由此发作。如果节制饮食、谨慎起居、适应寒暑、固护元气，以抵御外邪，即使患上此症，也为轻浅。嘉靖甲申年春天，南京大疫，煎煮圣散子，普遍救济老人小孩并让他们服用，来求医的人接踵而至，死者堵塞道路，实在令人哀悯！殊不知此方是因岭南风土而制定的，况且浙江与广东，相距万里，地域不同，天时人事，大不相同，岂有统一治疗而没有错误的呢！
In the spring and autumn seasons, people are affected by the miasma and fog of the mountains, developing alternating chills and fever (Han Re), chest and diaphragm fullness and oppression, and loss of appetite. This is because toxic vapors enter the body through the nose and mouth. Treatment should focus on clearing the Upper Jiao (Upper Burner), resolving internal toxins, moving Qi, and descending phlegm; sweating methods should not be used.
Main Formula:
Huanglian (Stir-fried with ginger juice), Huangqin, Muxiang, Nongpuo (Processed with ginger juice), Zhishi (Stir-fried with bran), Banxia (Washed after decoction), Jiegeng, Chaihu, Chuanxiong, Mutong (each 1 qian), Sheng Gancao (0.7 qian), Shengma, Cangzhu (Soaked in rice water, stir-fried with salt water, each 1.5 qian).
Decoct the above herbs with ginger and water, and take hot before meals.
My Commentary: Lingnan is a hot region bordering the sea, with low terrain and thin soil. Therefore, Yang Qi often leaks outward, while Yin Qi is often abundant. Flowers bloom in all four seasons, there is no frost or snow in winter, and heat accounts for more than half the year. In late December, prolonged sunshine may even cause people to fan themselves. People living here often have Qi stagnating upward, excessive sweating, and loose Cou Li (skin pores and interstices). This occurs because Yang Qi fails to return to its root. Once Yang Qi has leaked, the person's fundamental Qi becomes insecure. Yang Qi does not descend but floats upward. When Qi floats and lacks stability, the Xuan Fu (pores) open, making sweat easily lost. Thus, symptoms of internal cold and external heat, or upper heat and lower cold, arise. Treatment should primarily consolidate Yang Qi and strengthen the Cou Li. If dispersing and releasing exterior drugs are overused, Yang Qi will become more deficient, and Wind pathogen will flourish; few cases will avoid mismanagement. If the disease is caused by external pathogens, they should be dispersed. If the external pathogens are resolved but the illness persists, it indicates Lung Qi injury; use Buzhong Yiqi Tang (Spleen-Raising Qi-Supplementing Decoction). If the head and eyes feel unclear, it is due to Stomach Qi failing to ascend; add Manjingzi. If appetite is poor, it is Stomach Qi deficiency; use Sijunzi Tang (Four Gentlemen Decoction). If food is difficult to digest, it is Spleen Qi deficiency; use Liujunzi Tang (Six Gentlemen Decoction) plus Shaoyao and Danggui. If one fears cold, avoids cold drinks/food, or experiences acid regurgitation, it is Spleen Qi deficiency and cold; add Paogjiang (Pregnant Ginger) to the previous formula. If ineffective, add Wuzhuyu (0.4 qian) and Huanglian (0.2 qian). Other conditions should be treated based on deduction. Various symptoms of Lingnan miasma are detailed in the "Hygiene Chapter". Those traveling to this area should keep this book for frequent reference.
If temperature regulation is improper, such as removing clothes during sweating and catching Wind-Cold, leading to Qi blockage, fever, and headache, this belongs to the category of Shanghan (Cold Damage). However, Lingnan's warm climate causes easy sweating, so symptoms often resemble Nué (Malaria). Severe cases involve persistent chills and fever; mild cases are Nué. Southern Qi tends to rise, so Lingnan patients suffering from this condition suddenly present with chest fullness, phlegm-saliva obstruction, and inability to eat. This differs from Northern Shanghan, which only affects the exterior while the interior remains harmonious. Treatment should release the exterior, clear heat, descend Qi, and move phlegm. This formula is suitable for cold months, or warm months where Wind-Cold was contracted.
Qianghuo, Cangzhu (Soaked in rice water), Chaihu, Huangqin, Juhong, Banxia (Washed after decoction), Zhishi, Zhi Gancao (Honey-fried), Chuanxiong (each 1 qian).
Decoct with ginger and water, take before meals, including the dregs. Stop taking when sweat appears.
My Commentary: For the aforementioned symptoms, if there is internal food retention and external Wind-Cold contraction, use Huoxiang Zhengqi San (Patchouli Powder to Rectify the Qi). If Spleen Qi is weak with chills, fever, and vomiting, use Jinbuhuan San. Generally, in Lingnan, damp-heat steams, Cou Li do not close, fluids leak excessively, and internal Yang Qi is deficient. The method should prioritize regulating and tonifying Lung Qi. The Lung governs Qi and controls Cou Li; Lung Qi deficiency leads to loose Cou Li and fluid leakage, causing these symptoms. Once external pathogens are gone, tonify Spleen Earth to generate Lung Metal.
Zhang Nué (Miasma Malaria) and Shi Nué (Seasonal Malaria) with alternating chills and fever.
Chaihu, Zhimu (each 1.5 qian, stir-fried), Cangzhu (Soaked in rice water), Huangqin (Wine-fried), Gange, Chenpi, Banxia (Washed after decoction), Chuanxiong (each 1 qian), Zhi Gancao (0.7 qian, honey-fried).
Decoct with three slices of ginger and two dark plums (Wumei) in water. Take in the early morning and before noon.
My Commentary: For the aforementioned symptoms, if alternating chills and fever are due to unresolved external pathogens, use the original formula to disperse them. If due to inherent weak Spleen Qi, or if chills and fever persist after external pathogens are cleared by previous medicines, accompanied by nausea and poor appetite, this is Spleen Qi damage; use Buzhong Yiqi Tang plus Banxia, Gange, and Fuling for regulation. If chills and fever occur before noon, it belongs to Qi deficiency; use Sijunzi Tang plus Danggui and Shengma. If chills and fever occur after noon, it belongs to Blood deficiency; use Bazhen Tang plus Chaihu and Shengma. Generally, long-term illness causing Qi deficiency and weak Blood inevitably leads to fever; Tonify the Spleen and Stomach with formulas like Sijunzi Tang. Once the Spleen and Stomach are strong, Qi and Blood generate naturally. If mistakenly treated as Blood deficiency using heavy, yin-nourishing agents like Siwu Tang to directly generate Blood, the Spleen Earth will be further injured, affecting all organs, causing numerous deficiency syndromes, making treatment difficult, potentially fatal.
For chronic Nué, add Renshen (1.5 qian) and Danggui (1 qian). For excessive sweating, remove Cangzhu, replace with Baizhu, and add Shaoyao (wine-fried, 1.5 qian).
My Commentary: Chronic Nué that does not heal belongs to Middle Qi deficiency failing to nourish the organs; regulating and tonifying the Spleen and Stomach will resolve other diseases. Spontaneous sweating indicates Yang Qi deficiency failing to secure the Cou Li; use Sijunzi Tang plus Danggui, [missing character, likely Huangqi], and Chenpi. If ineffective, add Jiang and Rougui. Cold extremities require immediate addition of Fuzi. Night sweats indicate Yin deficiency and loose Cou Li; use Bazhen Tang plus Rougui and Wuweizi. Restlessness, heat, and thirst temporarily require Danggui Liu Huang Tang, where the three Huang herbs are charred, and double the amount of Renshen and [missing character]. Once sweating stops, resume Bazhen San. If Kidney Qi is inherently weak with fever and thirst, use Liuwei Wan. Cold extremities or Phlegm-Qi attacking upward require Bawei Wan. If pathogens are scattered but chills and fever persist, this is True Qi deficiency; use Buzhong Yiqi Tang. If Qi and Blood deficiency cause chills and fever, use Bazhen Tang. Improper treatment damages Yuan Qi, causing myriad changes, not just chronic Nué.
Nué transforming into Li Ji (Dysentery) should be treated as deficiency; thus, Spleen and Stomach tonics are used.
Huanglian (Stir-fried), Muxiang, Suosha, Huangqin (Stir-fried), Juapi, Baizhu, Danggui (Wine-washed, each 1 qian), Shaoyao (Stir-fried, 2 qian), Zhi Gancao (0.5 qian).
Decoct with ginger and water, take before meals.
My Commentary: The aforementioned symptoms result from excess Pathogenic Qi and insufficient Form Qi. Use the original formula to clear and resolve Stomach and Spleen pathogenic heat. If both Pathogenic Qi and Form Qi are insufficient and healing fails, use Buzhong Yiqi Tang to nourish the organs for self-healing.
In warm and summer months, if people suffer from epidemic febrile diseases, treatment should use heat-clearing and detoxifying agents, addressing both interior and exterior. After recovery, regulate the Spleen and Stomach to strengthen Yuan Qi.
Kuang Huangqin, Shengma, Gange, Zhimu (wine-fried, each 1 qian), Renshen, Shigao, Shaoyao (each 1.5 qian), Huanglian (wine-fried, 0.4 qian), Gancao (0.7 qian), Qianghuo (2 qian), Sheng Dihuang (wine-washed, 0.5 qian).
Decoct with ginger and water, take hot before meals, continue with dregs.
My Commentary: If the pathogen is in the Foot Yangming channel with unresolved exterior and interior, use this formula to harmonize. If excessive purging damages Stomach Qi, causing fever and thirst, use Zhuye Shigao Tang to generate fluids. If mistaken sweating causes Yang collapse with fever and thirst, use Shengyang Yiguo Tang. If mistaken purging causes Yin collapse with fever and irritability, use Lizhong Tang.
For chest/diaphragm oppression and phlegm-saliva obstruction, add Zhishi and Banxia (each 1 qian) and 4-5 spoons of fresh ginger juice. For unstable Spleen/Stomach, add Baizhu (1.5 qian).
My Commentary: If form and disease are both excess with phlegm-caused oppression, use this formula. If Spleen/Lung Qi is weak with untransformed phlegm causing oppression, use Liujunzi Tang with small amounts of Jiegeng and Zhike. If Spleen/Stomach weakness fails to control phlegm origin causing oppression, use Liujunzi Tang with Paogjiang.
If seasonal Qi fever transforms into Huang Bing (Jaundice), known as Wen Huang (Epidemic Jaundice), treatment should internally drain damp-heat.
Yinchen, Huanglian (fried with ginger water), Shanzhiren, Bai Fuling, Nongpuo (fried with ginger water), Mutong, Baizhu, Renshen (each 1 qian), Muxiang (0.7 qian), Shaoyao (wine-fried), Gange (each 1.5 qian).
Decoct with ginger and water, take before meals, continue with dregs.
My Commentary: If caused by damp-heat stagnation, use this formula. If due to long-term illness worsening Yuan Qi deficiency, with Spleen's true color appearing externally, use Buzhong Yiqi Tang plus Yinchen and Fuling. If Middle Qi deficiency-cold with cold extremities, edema, or black-yellow jaundice, use Renshen Lizhong Tang plus Fuling and Yinchen. Su Dongpo used Shengsanzi in Huangzhou, reflecting this intent. Locals did not understand, instead using Binglang to guide and damage True Qi, opening Cou Li, inviting external pathogens, and causing illness. If diet is regulated,起居 (daily routine) is cautious, cold/heat is adapted, and Yuan Qi is solidified to repel external pathogens, even if afflicted, the condition is mild. In the spring of Jiashen (Jiajing Year 3), a major epidemic occurred in Nanjing. Shengsanzi was decocted and distributed to old and young. Patients crowded in, and corpses blocked roads, which is truly pitiable! It is unknown that this formula was created for Lingnan's climate. Zhejiang and Guangdong are ten thousand li apart, different regions with distinct climates and human circumstances. How can uniform treatment without error be expected?
