论假热假寒
天师曰∶假治者，病是假热，而治以假热之方；症是假寒，而治以假寒之药也。如人喉痛口干，舌
燥身热，人以为热，而非热也。内真寒而外现假热耳。如人手足冰冷，或发厥逆，或身战畏寒，人以为
寒，而非寒也，内真热而外现假寒耳。此时看症未确，死生反掌。吾以假热之药，治假寒之症，以假寒
之品，治假热之病，是以假对假也，假寒方∶附子─钱，肉桂一钱，人参三钱，白术五钱，猪胆汁半
个，苦菜汁三匙。先将药二碗，水煎好，以冰水泡凉，入猪胆汁、苦菜汁调匀，一气服之即愈。方中全
是热药，倘服之不宜，必然虚火上冲，尽行呕出。吾以热药凉服，已足顺其性而下行，况又有苦菜汁、胆
汁之苦，以骗其假道之防也。盖上热之症，下必寒极，热药入之，至于下焦，投其所喜。无奈关门皆为
强贼所守，非以间牒 之，必然拒绝而不可入。内无粮草，外无救援，奈之何哉。吾今用胆汁、菜汁，
以与守关之士，买其欢心，不特不为拒绝，转能导我入疆，假道灭虢，不信然哉。
至于假热之方，则又不然。心胸之内，全是一团邪火，盘踞于中焦。若不直捣中坚，巨魁不擒，余
党安能星散。然
而用师无法，则彼且力拒死斗而不可救。方用黄连三钱，柴胡二钱，白芍三钱，当归三钱，炒栀子
二钱，半夏三钱，枳壳一钱，茯苓三钱，菖蒲三分，水煎服。此方妙在用黄连一味，直入心经；佐以栀

则热喜同热，不致相反；而转能相济，此又假治之妙法也。
张公曰∶讲得透彻痛快，予又何说之词。然而假热假寒，不止此二症也，吾再广言之。如人气喘不

黄汤，加麦冬、甘菊花、白芍、当归各三两，柴胡五钱，各为末，蜜为丸。每日吞服五钱，一料必全愈。
此虽病轻，而世人多患之，迷而不悟，予所以特表出也。虽非假治之法，而症实假热之症，可触类而旁通
之耳。假寒之法，莫妙岐天师
之方，可以统治矣，故不再传。
华君曰∶亦同。
天师说：所谓假治，是指病症表现为假热，却使用针对假热的方剂；症状表现为假寒，却使用针对假寒的药物。比如有人咽喉疼痛、口干舌燥、身体发热，人们以为是热证，其实并非热证，这是内部真寒而外部显现出假热的现象。又比如有人手脚冰冷，或者发生四肢厥逆，或者身体颤抖、畏寒，人们以为是寒证，其实并非寒证，这是内部真热而外部显现出假寒的现象。此时如果诊断病情不确切，生死就在转念之间。我用治疗假热的药物来治疗假寒的症状，用治疗假寒的药物来治疗假热的病证，这就是以假对假的方法。
假寒方的组成是：附子一钱，肉桂一钱，人参三钱，白术五钱，猪胆汁半个，苦菜汁三匙。先将前四味药加水两碗煎好，用冰水将药液泡凉，再加入猪胆汁和苦菜汁调匀，一次性服下即可痊愈。这个方子里全是热性药物，如果直接服用不合适，必然会导致虚火上冲，全部呕吐出来。我采用热药凉服的方法，已经足以顺应其性质使其下行，况且又有苦菜汁、胆汁的苦味，用来欺骗并突破假热在上的防御屏障。这是因为上焦有热症，下焦必定寒极，热药进入后，到达下焦，投其所好（因为下焦喜温）。无奈的是，下焦的“关门”都被强贼把守，如果不派间谍去疏通，必然会被拒绝而无法进入。内部没有粮草，外部没有救援，该怎么办呢？我现在用胆汁、菜汁，作为礼物送给把守关隘的士兵，博取他们的欢心，不仅不会被拒绝，反而能引导我军进入疆域，这正是“假道灭虢”的策略，难道不是这样吗？
至于假热方，则又不一样了。心胸之内，全是一团邪火，盘踞在中焦。如果不直捣中坚，擒获首恶，其余党羽怎能星散？然而如果用兵没有策略，敌人就会拼死抵抗，无法救治。方剂组成是：黄连三钱，柴胡二钱，白芍三钱，当归三钱，炒栀子二钱，半夏三钱，枳壳一钱，茯苓三钱，石菖蒲三分，水煎服。这个方子的妙处在于使用黄连一味药，直入心经；辅以栀子这员副将，单刀直入，使邪气无处遁形；再用柴胡、白芍切断敌人的运粮通道；再用半夏、枳壳斩杀残余党羽，中原平定之后，四方自然不战而降。然而火热居中，如果不是用药得当，贼势会更加空虚猖獗，怎么能直入呢？所以又加入辛热的石菖蒲，趁热饮用，那么热药喜欢同气相求的热环境，不会相互抵触，反而能互相协助，这又是假治法的精妙之处。
张公说：讲得透彻痛快，我还有什么话可说呢？然而假热假寒，不止这两种症状，我再广泛地论述一下。比如有人气喘不安，痰涎声如拉锯般不止，人们以为是热证，其实并非热证，这是下元极度寒冷，逼迫虚火上浮而导致气喘。这是最紧急最危险的病症，如果不急补命门之火与肾水，那么一线微弱的阳气必然断绝。方剂组成是：熟地黄四两，山茱萸三两，麦冬三两，北五味子一两，牛膝一两，附子一钱，肉桂一钱，用冰水泡冷后服用，一剂即可痊愈。附子、肉桂是斩关夺门的猛药，性质最热，如果不将它们置于熟地黄、山茱萸、北五味子之中，那么孤阳会乘着大热的势头，沸腾而上。方中的妙处在于使用熟地黄、山茱萸之类，足以济助火势；又用麦冬滋养肺金的化源，使金能生水，水足则能生火，火便不敢飞越，况且还有牛膝引药下行而不上行。但必须用冰水泡制，以欺骗上焦的热邪，使药力直达肾宫，肾宫得到温热，上焦自然清凉，火自归位，又何患气喘与痰涎作祟呢？更有眼睛红肿，经年不愈的人，人们以为是热证，却不知道并非热证，这也是肾火上升而不能下降所致。治法是用六味地黄汤，加上麦冬、甘菊花、白芍、当归各三两，柴胡五钱，各研为末，蜂蜜制成丸药。每天吞服五钱，一料药必能全愈。这虽然病轻，但世人多患此病，迷惑而不醒悟，所以我特意提出来说明。这虽然不是假治之法，但症状确实是假热之症，可以触类旁通。假寒的治疗方法，没有比岐天师（指文中提到的治疗假寒的高明医生）的方子更妙的了，可以统管此类病症，所以不再重复传授。
华君说：也是同样的看法。
Tian Shi (Heavenly Master) said: The so-called "treatment by deception" refers to using formulas intended for false heat to treat diseases manifesting as false heat, and using drugs intended for false cold to treat symptoms manifesting as false cold. For instance, if a person suffers from sore throat, dry mouth, dry tongue, and fever, people may assume it is a heat syndrome, but it is not actually heat; rather, it is true cold internally with false heat externally manifested. Conversely, if a person has ice-cold hands and feet, experiences limb reversal (Jue Ni), or trembles and fears cold, people may assume it is a cold syndrome, but it is not actually cold; rather, it is true heat internally with false cold externally manifested. At such times, if the diagnosis is not accurate, life and death can change in an instant. I use medicines for treating false heat to address symptoms of false cold, and medicines for treating false cold to address diseases of false heat; this is employing the false against the false.
The formula for false cold consists of: Fuzi (Aconite Lateralis Radix Preparata) 1 qian, Rougui (Cinnamomi Cortex) 1 qian, Renshen (Ginseng Radix) 3 qian, Baizhu (Atractylodis Macrocephalae Rhizoma) 5 qian, half a pig bile, and 3 spoons of bitter vegetable juice. First, decoct the first four herbs in two bowls of water. Then, cool the decoction by soaking it in ice water. Add the pig bile and bitter vegetable juice, mix well, and take all at once for immediate recovery. This formula contains entirely hot-natured drugs. If taken warm, they would likely cause deficient fire to rush upward and be vomited out entirely. By taking hot drugs cold, I sufficiently align with their nature to guide them downward. Moreover, the bitterness of the bitter vegetable juice and bile serves to deceive and bypass the defensive barriers established by the false heat above. This is because when there are heat symptoms in the upper jiao, the lower jiao must be extremely cold. When hot drugs enter and reach the lower jiao, they meet what is welcomed there. However, the "gates" of the lower jiao are guarded by "strong thieves" (pathogenic factors). Without sending in "spies" (the cooling/bitter agents), entry will surely be rejected. With no supplies inside and no reinforcements outside, what can be done? Now, I use bile and vegetable juice as gifts to win over the guards at the gate. Not only will they not reject us, but they will also guide our troops into the territory. This is precisely the strategy of "borrowing a path to destroy Guo," is it not?
As for the formula for false heat, it is different. Within the chest and heart, there is a mass of evil fire entrenched in the middle jiao. If one does not strike directly at the core to capture the chief culprit, how can the remaining factions scatter? However, if the military strategy is flawed, the enemy will resist to the death, making rescue impossible. The formula uses: Huanglian (Coptidis Rhizoma) 3 qian, Chaihu (Bupleuri Radix) 2 qian, Baishao (Paeoniae Radix Alba) 3 qian, Danggui (Angelicae Sinensis Radix) 3 qian, Chao Zhizi (Gardeniae Fructus Praeparatus) 2 qian, Banxia (Pinelliae Tuber) 3 qian, Zhiqiao (Aurantii Fructus Immaturus) 1 qian, Fuling (Poria) 3 qian, and Shichangpu (Acori Tatarinowii Rhizoma) 3 fen. Decoct in water and take orally. The brilliance of this formula lies in using Huanglian alone to penetrate directly into the Heart Meridian; assisted by Zhizi as a vice-general, striking straight in to disperse all evil; further using Chaihu and Baishao to cut off the enemy's supply lines; and employing Banxia and Zhiqiao to slaughter the remnants. Once the central plains are pacified, the four corners will submit without battle. However, since fire and heat reside in the center, if not used appropriately, the thief's momentum will become even more rampant, preventing direct penetration. Therefore, Shichangpu, which is pungent and hot, is added. Taking it while hot allows the hot medicine to harmonize with the hot environment, avoiding conflict and instead assisting each other. This is another subtle application of the treatment-by-deception method.
Lord Zhang said: Your explanation is thorough and satisfying; what more could I say? However, false heat and false cold are not limited to these two syndromes. Let me elaborate further. For example, if a person suffers from panting and restlessness, with phlegm-saliva sounding like sawing without cessation, people may assume it is heat, but it is not. It is due to extreme cold in the lower origin forcing fire to float upward, causing panting. This is the most urgent and critical syndrome. If one does not urgently tonify the Fire of the Gate of Life (Mingmen) and Kidney Water, that slender thread of weak yang will inevitably sever. The formula uses: Shudi (Rehmanniae Radix Praeparata) 4 liang, Shanzhuyu (Corni Fructus) 3 liang, Maidong (Ophiopogonis Radix) 3 liang, Bei Wuwei Zi (Schisandrae Fructus) 1 liang, Niuxi (Achyranthis Bidentatae Radix) 1 liang, Fuzi (Aconite Lateralis Radix Preparata) 1 qian, and Rougui (Cinnamomi Cortex) 1 qian. Take cold after soaking in ice water; one dose brings recovery. Fuzi and Rougui are potent drugs that break through gates and seize doors; their nature is extremely hot. If not placed within Shudi, Shanzhuyu, and Bei Wuwei Zi, the lone yang would surge upward boiling violently due to the intense heat. The妙 (wonder) of the formula lies in using Shudi and Shanzhuyu to sufficiently support the fire; Maidong nourishes the source of Lung Metal transformation, enabling Metal to generate Water, and sufficient Water generates Fire, preventing Fire from flying wildly. Furthermore, Niuxi guides the action downward rather than upward. Crucially, soaking in ice water deceives the heat of the upper jiao, allowing the medicine to reach the Kidney Palace. Once the Kidney Palace is warmed, the upper jiao becomes cool, and the fire returns to its residence. What worry remains regarding panting and phlegm? Additionally, some suffer from red and swollen eyes persisting for years. People assume it is heat, but do not realize it is not; it is also Kidney Fire rising and failing to descend. The method uses Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia), adding Maidong, Juhua (Chrysanthemi Flos), Baishao, and Danggui, each 3 liang, and Chaihu 5 qian. Grind all into powder and form pills with honey. Swallow 5 qian daily; one course guarantees complete recovery. Although this disease is mild, many people suffer from it, confused and unenlightened, so I specifically highlight it. Although this is not strictly a treatment-by-deception method, the symptoms are indeed false heat, allowing for analogical extension. Regarding the method for false cold, none is more exquisite than the formula of Tian Shi Qi (referring to the skilled physician mentioned earlier); it can govern such cases generally, so I will not repeat it.
Lord Hua said: I agree.
