吴又可用达原饮治瘟疫，善矣。但瘟之愈，终由汗解，往往有下后，而仍自解以汗者，是瘟

玉楸，颇与余意合。用之数年，历有成效，始敢笔之于书。并添三阴经治法，以补又可之所未及。
第医者，意也。兹不过规矩焉已耳。但有是方，未必有是病。神而明之，则又在存乎其人矣。
烦闷且阴囊收缩
厥阴经由风木之气主令，手厥阴心包络借风木之气而化生相火之气。其生理常态是木气条达从而化生温煦之气；若发病，则是火气郁结而生热。因为厥阴乙木原本禀受丁火之胎元，所以厥阴经脉最容易发生热证。瘟疫病邪闭塞卫分并遏制营血，营气郁滞因而发热。由于营血藏于肝脏，正值隆冬时节火气外泄，营血已经受损且沸腾躁动；若在春夏季节感受病邪，卫气闭塞、营气被遏，血热症状会更加剧烈。足厥阴肝经从足部走向胸部，行走在身体侧面，环绕阴器并联络肝脏，因此出现烦闷和阴囊收缩的症状。手厥阴的相火，借助足厥阴的风木之势，风助火势，烈火焚烧，煎熬逼迫营血，导致血液枯槁、性命终结，此时应当清散皮毛之邪，宣泄相火的炎上之势，并滋养风木之燥。方用苍霖丹主治。
苍霖丹：治疗厥阴经引起的烦闷、阴囊收缩、发热及口渴。

用流水煎煮至大半杯，趁热服用，覆盖衣物以取汗。
瘟疫病邪传入厥阴经时，邪热非常严重。如果木气荣润、血脉通畅，经络与脏腑得到润泽，营分之热不能内传，当六经病变遍及各经后，若无其他出路，则郁积至极而从外部发出，表现为红斑。如果营气虚弱不能透发，过了适当时间才出斑，且颜色呈紫黑色，说明营血败坏损伤，大多难以救治。此时应当解表凉血，使营分之热得以发散，也使用苍霖丹主治。
吴又可使用达原饮治疗瘟疫，是很好的方法。但是瘟疫痊愈，终究是通过汗法解除，往往有经过攻下治疗后，仍然通过出汗而自愈的情况，这说明瘟疫需要汗法，恐怕情况紧急。因此想到能发瘟疫之汗的，没有比得上浮萍的，它性质凉散，入肺经，通达皮肤，发汗作用甚于麻黄，本草中记载得很详细。我偶尔用它治疗瘟疫，总是有效。后来向北海老医黄玉楸请教，他的观点与我颇为契合。使用它数年，屡次取得成效，才敢将其记录在书中。并补充了三阴经的治疗方法，以弥补吴又可未涉及之处。只是医者，重在意会。这里不过是提供规矩准则罢了。有了这个方子，未必一定对应这种病。若能神妙地阐明其理，则全在于医者本人的悟性了。
Vomiting and Retraction of the Scrotum
The Jueyin (Jueyin, 厥阴) channel is governed by the Wind-Wood qi. The Hand Jueyin Pericardium transforms into Ministerial Fire (Xianghuo, 相火) within the context of Wind-Wood. In health, Wood qi flows freely to generate warmth; in disease, Fire qi becomes stagnant and generates heat. Since Jueyin Yi-Wood originally embodies Ding-Fire, the Jueyin channels are most prone to heat pathologies. In epidemic febrile diseases (Wenbing, 瘟病), Wei (Defensive) closure obstructs Ying (Nutritive) blood, causing Ying stagnation and subsequent fever. As Ying blood resides in the Liver, during deep winter when Fire qi leaks outward, Ying blood is already damaged and turbulent. If contracted in spring or summer with Wei closure and Ying obstruction, blood-heat becomes even more severe. The Foot Jueyin Liver Channel ascends from the foot to the chest, runs along the lateral aspect of the body, circles the genitalia, and connects with the Liver; thus, it presents with vexation, fullness, and retraction of the scrotum. The Ministerial Fire of the Hand Jueyin fans the Wind of the Foot Jueyin; wind aids fire, intense flames scorch and press upon Ying blood, leading to desiccation and death. Treatment should clear and disperse the skin and hair, vent the blazing Ministerial Fire, and nourish the dryness of Wind-Wood. Canglin Dan (Canglin Decoction) is the primary formula.
Canglin Dan: Treats Jueyin vexation, scrotal retraction, fever, and thirst.
* *Poria Cocos* (Fuping, 浮萍) - 2 qian
* *Rehmanniae Radix Preparata* (Shengdi, 生地) - 4 qian
* *Paeoniae Radix Alba* (Shaoyao, 芍药) - 2 qian
* *Angelicae Sinensis Radix* (Danggui, 当归) - 2 qian, washed with wine
* *Moutan Cortex* (Danpi, 丹皮) - 2 qian
* *Glycyrrhizae Radix et Rhizoma* (Gancao, 甘草) - 5 fen
* *Zingiberis Rhizoma Recens* (Shengjiang, 生姜) - 2 qian
Decoct with flowing water until half a cup remains. Take hot, then cover with clothing to induce sweating.
Eruptions on the Jueyin Channel
When epidemic pathogens transmit to the Jueyin channel, evil heat becomes extreme. If Wood qi is flourishing and blood flows smoothly, meridians and zang-fu organs are moistened, and Ying-heat cannot transmit internally. After traversing all six channels without another outlet, the accumulated heat erupts externally as red macules. If Ying deficiency prevents eruption, and macules appear late with purple-black coloration, it indicates destruction of Ying blood, often resulting in untreatable conditions. Treatment should release the exterior and cool the blood to allow Ying-heat to dissipate; Canglin Dan is also indicated here.
Wu Youke’s use of Daren Yin (Daren Decoction) for plague was excellent. However, recovery from plague ultimately depends on resolution through sweating. Often, after purgation, spontaneous sweating still occurs, indicating that plague requires diaphoresis, which may be urgent. I considered that nothing surpasses Fuping (*Poria Cocos*) for inducing sweat in plague. Its nature is cool and dispersing, entering the Lung Channel, reaching the skin, and inducing sweat more powerfully than Mahuang (*Ephedrae Herba*). This is well-documented in materia medica. I occasionally used it to treat plague with consistent efficacy. Later, I consulted Huang Yuqiu, an old physician from Beihai, whose views aligned closely with mine. After years of successful application, I dared to record this in writing. I added treatment methods for the Three Yin channels to supplement what Youke omitted. Yet, medicine relies on intuition. These are merely guidelines. Having the formula does not guarantee the disease matches it. Divine understanding depends entirely on the practitioner.
