万物之生也，人为最灵；四时有变兮，百疾兆生。欲辨阴阳之证，必明天地
之情。稽寒温表里之疑，式明标本；施汗、下、补、吐之法，溥济群生。
始而毫毛，次传肤腠。恶风自汗，乃桂枝之证；喘热恶寒，则麻黄之候。阴
阳俱虚而身必痒，各半同功（桂枝麻黄各半汤代）；寒热共作而脉尚虚，二、一共
凑（桂枝二越婢一汤）。
于是助以姜、枣，杂以豉、葱。便利、恶风者，干姜；心悸、腹痛者，建中。脉热极而烦者，
入人参于白虎；脉烦盛而喘者，加杏子以青龙。结胸、下利而表解，朱雀取效；头眩肉 而水泄，玄武当功。
致使橘梗宽咽，甘草平悸。腹内胀满兮，浓朴、姜；心中懊 兮，栀子、豉。
小便不利，则投之以猪苓；膈间有痰，则吐之以瓜蒂。或乃热作而腹胁胀满；又
若狂妄而潮热发悸。或里已入而表未除，或小便涩而大便秘。必明大、小柴胡，
直叙前后承气。结胸多渴，祝侍者议任陷胸；谵语发狂，委将军（即大黄）功先调胃。
当知青龙、十枣兮，水分表、里；三黄、四逆兮，利有寒、温。下利者通脉，烦躁者茯苓（茯苓
四逆汤）。脉绝用当归（当归四逆汤），亡血须人参（四逆加人参）；汗出加附子（附子泻心汤），恶
风入黄芩（黄芩泻心汤），胁下有水则生姜（生姜泻心汤），心中呕逆则人参（人参泻心汤）。上四者，
总归于四逆；下四者，类同于泻心。温寒实而解结胸，美三白之功妙；生津液而逐水道，嘉五苓之用深。
唾血则黄 宜服，便脓则桃仁可加。黄胆，茵陈必先求之瓜蒂（先瓜蒂后茵
陈）；斑毒，紫雪当后用于升麻（先升麻后紫雪）。温湿之于桂、附、苍术可入；理中之内参姜，附子宜加。
此外若青龙与柴胡有加减之余议∶身有余热者，桂枝须加；胁下硬满者大枣可去；多汗者附子加
小柴胡；奔豚者桂枝加桂；喘者小青龙加杏仁；嗽者小柴胡加五味。瓜蒂治烦渴未除，茯苓医小
便不利。内寒者茱萸，外肿者防己。生姜止呕，半夏疗哕。用枳壳兮，缘酒毒留胸；有黄柏兮，因衄血出
鼻。或得人参以除烦，或取茯苓而愈悸。头痛如破，葱白连须；咳逆欲绝，干柿并蒂。下利则干
姜，身痛则栀豉。岂二方之独用，亦众药之同推。妙哉！吾今精此四十余年，活人之功尝识。
Among all living things, humans are the most spiritual; as the four seasons change, various diseases arise. To distinguish yin and yang syndromes, one must understand the principles of heaven and earth. Investigating the doubts of cold and heat, exterior and interior, clarifies the root and branch (Ben-Biao); administering methods of sweating (Han), purging (Xia), tonifying (Bu), and vomiting (Tu) broadly benefits all living beings.
The pathogen initially affects the hair follicles, then transmits to the skin and interstices. Aversion to wind and spontaneous sweating indicate a Guizhi Tang (Cinnamon Twig Decoction) syndrome; wheezing, fever, and aversion to cold indicate a Mahuang Tang (Ephedra Decoction) pattern. When both yin and yang are deficient and the body itches, Guizhi Mahuang Gehan Tang (Guizhi and Mahuang Half-Combined Decoction) acts synergistically; when chills and fever alternate and the pulse is still deficient, Guizhi Er Yuebi Yi Tang (Guizhi Twice-Yuebi Once Decoction) should be combined.
Thereupon, ginger and jujube are assisted, mixed with fermented soybean and scallion. For free urination and defecation but aversion to wind, Ganjiang (Dried Ginger) is used; for palpitations and abdominal pain, Jianzhong Tang (Middle-Joint Building Decoction) is indicated. For an extremely hot pulse and vexation, Renshen (Ginseng) is added to Baihu Tang (White Tiger Decoction); for a vexatious and surging pulse with wheezing, Xingren (Apricot Kernel) is added to Qinglong Tang (Azure Dragon Decoction). For chest binding (Jie Xiong), diarrhea, and resolved exterior syndrome, Zhuque Tang (Vermilion Bird Decoction) yields results; for dizziness, muscle twitching, and watery diarrhea, Xuanwu Tang (Black Tortoise Decoction) achieves efficacy.
Thus, Jiegeng (Platycodon Root) widens the throat, and Gancao (Licorice Root) calms palpitations. For abdominal fullness, Houpo (Magnolia Bark) and Shengjiang (Fresh Ginger) are used; for mental restlessness and oppression in the heart, Zhizi (Gardenia Fruit) and Chishi (Fermented Soybean) are employed. For difficult urination, Zhuling Tang (Polyporus Decoction) is administered; for phlegm-rheum in the diaphragm, Gouti San (Melon Seed Powder) induces vomiting. Or, when heat arises with abdominal and hypochondriac fullness; or again, when madness occurs with tidal fever and palpitations. When the interior is affected but the exterior remains unresolved, or when urination is scanty and stool is constipated, one must clearly distinguish between Da Chaihu Tang (Major Bupleurum Decoction) and Xiao Chaihu Tang (Minor Bupleurum Decoction), and directly narrate the applications of Da Chengqi Tang (Major Order the Qi Decoction) and Xiao Chengqi Tang (Minor Order the Qi Decoction). Chest binding often involves thirst, so the practitioner should rely on Xianxiong Tang (Depress the Chest Decoction); delirium and madness require Dahuang (Rhubarb) to first regulate the stomach.
One should know that Qinglong Tang (Azure Dragon Decoction) and Shizao Tang (Ten Jujube Decoction) address water retention in the exterior or interior; Sanhuang Tang (Three Yellows Decoction) and Sini Tang (Reversed Extremities Decoction) address dampness with cold or warmth. For diarrhea, Tongmai Sini Tang (Pulse-Reviving Reversed Extremities Decoction) is used; for irritability, Fuling Sini Tang (Poria Reversed Extremities Decoction) is indicated. For absent pulse, Danggui Sini Tang (Angelica Reversed Extremities Decoction) is used; for blood loss, Renshen (Ginseng) is required (Sini Jia Renshen Tang). For sweating, Fuzi (Aconite Root) is added (Fuzi Xiexin Tang); for aversion to wind, Huangqin (Scutellaria Root) is included (Huangqin Xiexin Tang); for water under the hypochondrium, Shengjiang (Fresh Ginger) is added (Shengjiang Xiexin Tang); for nausea and vomiting in the heart, Renshen (Ginseng) is added (Renshen Xiexin Tang). The former four cases generally belong to Sini Tang categories; the latter four cases are similar to Xiexin Tang categories. Warming cold excess and resolving chest binding praises the subtle merit of "Sanbai" (Three Whites) decoctions; generating fluids and unblocking water pathways appreciates the profound use of Wuling San (Five-Ingredient Powder with Poria).
For hemoptysis, Huangqin (Scutellaria Root) is suitable; for pus in stool, Taoren (Peach Kernel) can be added. For jaundice, Yinchen Hao Tang (Artemisia Capillaris Decoction) is sought first, but Gouti (Melon Seed) should be used prior (first emetic, then clearing); for macular toxins, Zixue Dan (Purple Snow Pill) should be used after Shengma Gegen Tang (Cimicifuga and Kudzu Decoction) (first releasing the exterior, then clearing heat). For warming and drying dampness, Guizhi (Cinnamon Twig), Fuzi (Aconite Root), and Cangzhu (Atractylodes Rhizome) can be entered; within Lizhong Tang (Regulate the Middle Decoction), adding Jiang (Ginger) and Fuzi (Aconite) is appropriate.
Furthermore, regarding additional discussions on modifications of Qinglong Tang and Chaihu Tang: for residual heat in the body, Guizhi Tang requires additions; for hardness and fullness under the hypochondrium, Dazao (Jujube) can be removed; for excessive sweating, Fuzi (Aconite Root) is added to Xiao Chaihu Tang (Minor Bupleurum Decoction); for Ben Tun (Running Piglet Qi), Guizhi Jia Gui Tang (Guizhi Plus Cinnamon Twig Decoction) is used; for wheezing, Xingren (Apricot Kernel) is added to Xiao Qinglong Tang (Minor Azure Dragon Decoction); for coughing, Wuweizi (Schisandra Berry) is added to Xiao Chaihu Tang (Minor Bupleurum Decoction). Gouti (Melon Seed) treats persistent vexation and thirst; Fuling (Poria) treats difficult urination. For internal cold, Zhuyu (Cornus Fruit) is used; for external swelling, Fangji (Stephania Root) is employed. Shengjiang (Fresh Ginger) stops vomiting, Banxia (Pinellia Tuber) treats hiccups. Using Zhike (Bitter Orange Peel) is due to alcohol toxin lingering in the chest; using Huangbo (Phellodendron Bark) is due to epistaxis. One may obtain Renshen (Ginseng) to remove vexation, or take Fuling (Poria) to cure palpitations. For severe headache like breaking, Congbai Lianxu (Scallion White with Roots) is used; for coughing and rebellious qi nearing exhaustion, Ganshi Bingdi (Dried Persimmon with Peduncle) is employed. For diarrhea, Ganjiang (Dried Ginger) is used; for body pain, Zhichi Tang (Gardenia and Fermented Soybean Decoction) is applied. Is it not just the exclusive use of these two formulas, but also the common recommendation of many herbs? Wonderful! I have refined this knowledge for over forty years, and my merit in saving lives has been witnessed.
