世有城市之中，乡村镇店之处，传染瘟疫，多至死亡。其症必头痛眩晕，胸膈
膨胀，口吐黄痰，鼻流浊水，或身发红斑，或发如焦黑，或呕涎如红血，或腹大如圆箕，或舌
烂头大，或胁痛心疼，种种不一，象形而名，人以为天灾流行，谁知皆人事召之也。此症虽

抑其性，蕴藏于腹中，所以大闭作热，热闭成毒，其由来者，非一日也。治法自宜大泻其火
毒，以快泄其郁闷之气。第泻火之药，未有不大寒者也，不先用表散之味，遽用寒凉，火转闭
塞而不得达，适所以害之也。故必须于散中用泻，则疫去如扫耳。方用散瘟汤∶
荆芥（三钱） 石膏（五钱） 玄参（一两） 天花粉（三钱） 生甘草（一钱） 黄
芩（二钱） 陈皮（一钱） 麦芽（二钱） 神曲（三钱） 茯苓（五钱）水煎服。一剂病

疫鬼何能作祟哉。
余又闻南阳张真人之教，谓瘟疫自来无方，然方亦可豫定，以瘟病皆热症也。去火退热，
解邪逐秽，未尝不可于难定之中以定一可救之剂也。其方用∶
大黄（一钱） 荆芥（一钱） 生甘草（一钱） 柴胡 苍术 川芎（各一钱） 白
芷（五分）水二碗，煎八分。一剂回春。
此方较散瘟汤少异，然散火为主，其意正同。瘟疫治法，不可拘执，又志此方于后，以便
治疫者之采择也。
伯高太师，别号怀真子，传铎元天苦救汤，治前瘟疫亦甚效，并附于后∶
苦参（五钱） 元参（一两） 天花粉（五钱）三味水煎服。服一剂必无性命之忧。
又云∶偶传瘟疫，眼角忽然大肿，身子骤发寒热，喉咙大胀作痛，数日之后，即鼻中出
血，口出狂言，见人骂詈，发渴，若饮之水，则又泻痢不止，不过半月，其人即亡。一见眼角
发肿，即用七星汤治之，二剂即愈。若至泻痢，此方不可救矣。方另用加味术苓汤救之，痢

七星汤，治传染瘟疫，眼角忽然大肿，身骤发寒热，喉咙大胀作痛，骂詈发渴。
玄参 麦冬（各一两） 天花粉（三钱） 甘草（一钱） 荆芥（二钱） 神曲（一
钱） 桔梗（二钱）水煎服。若鼻中出血，加犀角（一钱），切不可用升麻代之，宁用黄芩一、二钱。
加味术苓汤∶治前症瘟疫，鼻中出血后饮水泻痢。
白术（五钱） 茯苓（一两） 贯众（一两） 甘草（二钱） 车前子（五钱）水煎服。痢止则生，否则不救。
世间城市、乡村集镇，常有瘟疫传染，导致大量死亡。其症状必定包括头痛眩晕、胸膈部胀满膨胀、口吐黄痰、鼻流浊涕，或者身上出现红斑，或皮肤发黑如焦灼状，或呕吐涎沫如同红血，或腹部肿大像圆簸箕，或舌头溃烂且舌体肿大，或胁肋疼痛、心区疼痛，各种症状不一而足，因形命名。人们以为是天灾流行，却不知这都是人事（行为/环境因素）所招致的。这种病症虽然千奇百怪，不能拘泥于一种情况来论述，但都是因为火热之毒不能宣散，郁结而成。大概火的性质是炎上，郁结则火气无法舒展，违背压抑其本性，蕴藏在腹中，所以导致大闭结而生热，热闭结而成毒，这由来已久。治疗方法自然应当大力泻除火毒，以畅快宣泄郁闷之气。只是泻火的药物，没有不是大寒性质的，如果不先用解表发散的药物，就急于使用寒凉药，火邪反而被闭塞而不能外达，这恰恰是害了病人。所以必须在发散之中配合泻下，这样瘟疫才能如扫除般去除。方用散瘟汤：荆芥（三钱）、石膏（五钱）、玄参（一两）、天花粉（三钱）、生甘草（一钱）、黄芩（二钱）、陈皮（一钱）、麦芽（二钱）、神曲（三钱）、茯苓（五钱），水煎服。服一剂病势减轻，服两剂病更轻，服三剂痊愈。此方主要泻肺胃之火，因为瘟疫的热邪，多是肺胃二经的火邪。用荆芥来辅助石膏、黄芩，既泻火又散火，火散则热邪发于体表，火泻则毒邪化解于体内，火解毒消，瘟神疫鬼怎能作祟呢？
我又听说南阳张真人的教诲，认为瘟疫向来没有固定的方子，然而方子也可以预先制定，因为瘟病都是热症。去火退热，解邪逐秽，未尝不能在难以确定的病情中确定一个可救命的药剂。其方用：大黄（一钱）、荆芥（一钱）、生甘草（一钱）、柴胡、苍术、川芎（各一钱）、白芷（五分），水二碗，煎至八分。服一剂即可回春。
此方与散瘟汤略有不同，但以散火为主，用意完全相同。瘟疫的治疗方法，不可拘泥固执，又将此方记录在后面，以便治疗瘟疫者参考选择。
伯高太师，别号怀真子，传授给我元天苦救汤，治疗前述的瘟疫也非常有效，一并附在后面：苦参（五钱）、元参（一两）、天花粉（五钱），三味药水煎服。服一剂必定没有性命之忧。
又说：偶然感染瘟疫，眼角突然大大肿胀，身体骤然发生寒热交替，喉咙大大肿胀疼痛，数日之后，即鼻孔出血，口中说狂话，见人便骂詈，感到口渴，如果喝水，则又腹泻痢疾不止，不过半个月，那人就会死亡。一见眼角发肿，立即用七星汤治疗，两剂即愈。如果发展到腹泻痢疾，此方就不能救了。另用加味术苓汤来抢救，痢止则生，否则不救。宁可传播方子以预防瘟疫，不可有瘟疫而无方子，所以详尽叙述出来，不敢隐瞒。两个方子记载在后面。
七星汤，治疗传染性瘟疫，眼角突然大大肿胀，身体骤然发生寒热，喉咙大大肿胀疼痛，骂人发渴。玄参、麦冬（各一两）、天花粉（三钱）、甘草（一钱）、荆芥（二钱）、神曲（一钱）、桔梗（二钱），水煎服。如果鼻孔出血，加犀角（一钱），切不可用升麻代替，宁可用黄芩一、二钱。
加味术苓汤：治疗前述瘟疫症状，鼻孔出血后饮水导致的腹泻痢疾。白术（五钱）、茯苓（一两）、贯众（一两）、甘草（二钱）、车前子（五钱），水煎服。痢止则生，否则不救。
In cities, villages, and market towns, plague is often transmitted, leading to numerous deaths. The symptoms invariably include headache and dizziness (Tóu tòng xuàn yùn), distension in the chest and diaphragm (Xiōng gé péng zhàng), expectoration of yellow phlegm (Kǒu tǔ huáng tán), and flow of turbid nasal discharge (Bí liú zhuó shuǐ). Alternatively, there may be red rashes on the body (Shēn fā hóng bān), skin turning black like scorched material (Fā rú jiāo hēi), vomiting saliva resembling red blood (Ǒu xián rú hóng xuè), abdominal enlargement like a round winnowing basket (Fù dà rú yuán jī), ulceration of the tongue with significant swelling (Shé làn tóu dà), pain in the hypochondrium and heart region (Xié tòng xīn téng), among other varied manifestations. Named after their shapes, people attribute this to heavenly disasters, yet they fail to realize that it is all caused by human factors (Rén shì). Although these symptoms are bizarre and cannot be discussed rigidly, they are all due to the accumulation and stagnation of heat-fire toxicity (Huǒ rè zhī dú) that fails to disperse. Fire naturally flares upward; when stagnant, its energy cannot extend freely. Suppressed and constrained, it accumulates within the abdomen, causing severe closure and heat generation. Heat closure forms toxicity, a process that develops over time. Therefore, the treatment method should ideally involve vigorously purging fire toxicity to rapidly relieve the stagnant Qi. However, herbs that purge fire are inherently cold in nature. If one does not first use exterior-releasing agents but instead abruptly applies cold-cooling herbs, the fire pathogen becomes further blocked and unable to reach the exterior, which ultimately harms the patient. Thus, one must combine dispersing methods with purging methods so that the epidemic can be swept away. The formula used is Sanwen Tang (Scatter Plague Decoction): Jingjie (Sanqian, Schizonepetae Spica), Shigao (Wuqian, Gypsum Fibrosum), Xuanshen (Yiliang, Scrophulariae Radix), Tianhuafen (Sanqian, Trichosanthis Radix), Sheng Gancao (Yiqian, Glycyrrhizae Radix et Rhizoma), Huangqin (Erqian, Scutellariae Radix), Chenpi (Yiqian, Citri Reticulatae Pericarpium), Maiya (Erqian, Hordei Fructus Germinatus), Shenqu (Sanqian, Massas Medicatae Fermentatae), Fuling (Wuqian, Poria). Decoct in water and take orally. After one dose, the illness lightens; after two doses, it lightens further; after three doses, full recovery occurs. This formula primarily purges fire from the Lung and Stomach meridians, as the heat of plague often stems from fire in these two meridians. Jingjie assists Shigao and Huangqin to both purge and disperse fire; when fire disperses, heat emerges outward; when fire is purged, toxicity resolves inward. With fire cleared and toxicity eliminated, how can plague spirits cause harm?
I have also heard the teachings of Zhang Zhenren from Nanyang, who stated that plague has traditionally lacked fixed formulas, yet formulas can be predetermined because plague diseases are always heat syndromes. To eliminate fire, reduce heat, resolve pathogens, and expel filth, it is indeed possible to determine a life-saving agent amidst uncertainty. The formula uses: Dahuang (Yiqian, Rheumii Radix et Rhizoma), Jingjie (Yiqian, Schizonepetae Spica), Sheng Gancao (Yiqian, Glycyrrhizae Radix et Rhizoma), Chaihu, Cangzhu, Chuanxiong (each Yiqian), Baizhi (Wufen, Angelicae Dahuricae Radix). Use two bowls of water, decoct until eight-tenths remain. One dose brings back vitality.
This formula differs slightly from Sanwen Tang, but its primary focus on dispersing fire shares the same intent. Treatment methods for plague must not be rigidly adhered to; thus, this formula is recorded below for practitioners to select from.
Master Bogao, courtesy name Huaizhenzi, passed down Yuantian Kujiu Tang (Heavenly Bitter Salvation Decoction) to me, which is also very effective for treating the aforementioned plague, and is attached here: Kushen (Wuqian, Sophorae Flavescentis Radix), Yuanshen (Yiliang, Scrophulariae Radix), Tianhuafen (Wuqian, Trichosanthis Radix). Decoct these three herbs in water and take orally. One dose ensures no threat to life.
It is also said: In occasional cases of plague infection, the corners of the eyes suddenly swell significantly, the body suddenly experiences alternating chills and fever, and the throat swells greatly and hurts. Several days later, bleeding occurs from the nose, delirious speech ensues, cursing and scolding occur upon seeing people, thirst arises, and drinking water leads to incessant diarrhea and dysentery. Within half a month, the person dies. Upon seeing swollen eye corners, immediately treat with Qixing Tang (Seven Stars Decoction); two doses result in cure. If it progresses to diarrhea and dysentery, this formula cannot save the patient. Instead, use Jiawei Shuling Tang (Modified Atractylodes and Poria Decoction) for rescue; if dysentery stops, the patient lives, otherwise, they do not survive. It is better to disseminate formulas for plague prevention than to have plague without remedies; therefore, I describe them fully, hiding nothing. The two formulas are recorded below.
Qixing Tang treats contagious plague characterized by sudden significant swelling of the eye corners, sudden onset of chills and fever, severe throat swelling and pain, cursing, and thirst. Xuanshen, Maidong (each Yiliang, Ophiopogonis Radix), Tianhuafen (Sanqian, Trichosanthis Radix), Gancao (Yiqian, Glycyrrhizae Radix et Rhizoma), Jingjie (Erqian, Schizonepetae Spica), Shenqu (Yiqian, Massas Medicatae Fermentatae), Jiegeng (Erqian, Platycodonis Radix). Decoct in water and take orally. If nasal bleeding occurs, add Xijiao (Yiqian, Rhinocerotis Cornu); do not substitute with Shengma under any circumstances; preferably use Huangqin (one or two qian, Scutellariae Radix).
Jiawei Shuling Tang treats the aforementioned plague symptoms where nasal bleeding is followed by diarrhea and dysentery induced by drinking water. Baizhu (Wuqian, Atractylodis Macrocephalae Rhizoma), Fuling (Yiliang, Poria), Guanzhong (Yiliang, Cibotii Rhizoma), Gancao (Erqian, Glycyrrhizae Radix et Rhizoma), Cheqianzi (Wuqian, Plantaginis Semen). Decoct in water and take orally. If dysentery stops, the patient lives; otherwise, they do not survive.
