凡瘟疫之流行，皆有秽恶之气，以鼓铸其间。试观入瘟疫之乡，是处动有青蝇，千百为群。
夫青蝇乃喜秽之物，且其鼻最灵，人所不闻，而蝇先闻之，故人粪一抛，而青蝇顿集，以是知青
蝇所聚之处，皆疫邪秽气之所钟也。更兼人之秽气，又有与之相济而行者。凡凶年饥岁，僵尸遍野，
臭气腾空，人受其熏触，已莫能堪，又兼之扶持病疾，敛埋道 ，则其气之秽，又洋洋而莫可御
矣。夫人而日与此二气相习，又焉得不病者乎！使不思所以除之，纵服药亦不灵，即灵矣，幸愈
此一二人，而秽气之弥沦布 者，且方兴而未有艾也，可不大畏乎！兹定数方，开列于下，倘瘟疫
之乡，果能焚烧佩带，则不觉，秽气之潜消，而沉 之顿起矣。
除秽靖瘟丹 （自定新方。将药末装入绛囊，约二三钱，毋太少，阖家分带，时时闻臭，已病
易愈，未病不染。）
苍术 降真香 川芎 大黄（各二钱） 虎头骨 细辛 斧头木（系斧柄入斧头之木） 鬼
箭羽 桃枭（小桃干在树者） 白檀香 羊踯躅 羌活 甘草 草乌 本 白芷 荆芥 干葛
皮 山甲 羚羊角 红枣 干姜 桂枝 附子 锻灶灰 川椒 山奈 甘松 排草 桂皮（各一钱，共为粗末）
明雄（二钱） 朱砂（二钱） 乳香（一钱） 没药（一钱，四味另研，共和）
苍降反魂香 （自定。）
苍术 降真香（各等分）
共末，揉入艾叶内，绵纸卷筒，烧之，除秽祛疫。
凡是瘟疫流行，都有污秽恶浊之气在其中酝酿鼓动。试看进入瘟疫流行的地方，到处常常有成群的苍蝇，成百上千聚集在一起。
苍蝇是喜欢污秽的东西，而且它们的鼻子最灵敏，人闻不到的气味，苍蝇先闻到了，所以人刚抛出粪便，苍蝇就立刻聚集过来，由此可知苍蝇聚集的地方，都是疫邪污秽之气汇聚之处。再加上人的污秽之气，又有与之相互助长而行的。凡是在灾荒饥馑之年，荒野遍野都是尸体，臭气冲天，人受到这种气味的熏染触碰，已经难以忍受，再加上还要扶持病人、收敛埋葬尸体，那么那种气味的污秽程度，更是盛大而无法抵御了。人如果每天与这两种气息相习相处，又怎么能不生病呢！如果不思考去除它们的方法，即使服药也不见效，即便有效，侥幸治好了这一两个人，但弥漫散布的污秽之气，正兴起而没有止境，这难道不值得大大警惕吗！现在制定几个方子，开列在下面，如果在瘟疫流行的地方，确实能够焚烧或佩戴这些药物，就会不知不觉地使污秽之气暗中消散，而沉疴痼疾顿时痊愈。

Wherever plagues (epidemic diseases) prevail, there is always foul and noxious qi fermenting and circulating within. Observe that when entering an area affected by plague, bluebottle flies are frequently seen everywhere, gathering in groups of hundreds or thousands.
Bluebottle flies are creatures fond of filth, and their sense of smell is extremely acute; they detect odors imperceptible to humans. Thus, as soon as human excrement is discarded, the flies immediately congregate. From this, we can infer that places where flies gather are precisely where the pathogenic qi of plague and filth accumulates. Furthermore, human filth qi often acts in conjunction with and reinforces this external foulness. In years of famine and disaster, corpses litter the fields, and putrid odors rise into the sky. Humans subjected to this miasma find it unbearable. Moreover, those who assist the sick and bury bodies on the roadside encounter a level of filth that is overwhelming and insurmountable. If people daily accustom themselves to these two types of qi, how could they avoid falling ill? If one does not consider methods to eliminate them, even if medicinal decoctions are taken, they will be ineffective. Even if they were effective, sparing only one or two individuals, the pervasive and spreading filth qi would continue to flourish without end. Is this not a matter for grave concern? Therefore, several prescriptions have been formulated and listed below. If, in plague-stricken areas, these substances are indeed burned or worn as amulets, the latent dissipation of filth qi will occur imperceptibly, and severe illnesses will suddenly resolve.
