疫邪夹疝，其肾囊少腹引痛，全是疝证，当照辨气、色、神、脉、舌苔法辨之。一有疫邪，不必治疝，但治疫
而疝自消。若根据常治疝法，用吴萸、桂、附、茴香诸燥品，轻者变为囊痈，重者变为呃逆、哕、厥、沉昏而莫救矣。
时疫有兼心胃痛者，于其痛时，察其气、色、神、脉、舌苔。若有一于时疫，但治时疫，虽平时因寒而发，
此则惟治其热。盖以疫邪客于募原，传于太阴，而发心胃痛之痼疾，于达原饮中加木香、苍术，以开通郁疫，
使其透发于表而痛自已。若误认平常心胃痛，用桂，附、姜、萸，必致危殆。
哮喘乃肺家素有痰火，一受疫邪，其湿热之气从其类而入肺，发其哮喘。遇此当察其气、色、神、脉、舌苔，
有疫但治疫，其哮喘自除。于治疫药中加贝母、栝蒌、淡豉、桑皮，疫邪、哮喘并解，法更精密。
以上诸条，凡言兼者。疫邪兼他邪，二邪自外入者也。凡言夹者，疫邪夹内病，内外夹发者也。二邪兼发，
以疫为重，他邪为轻，故略兼治他邪而病即解。二邪夹发，如夹水、食、血、气、痰等实邪，则以夹邪为先，疫
邪为后。盖清其夹邪，而疫毒始得透达，透达方能传变，传变方能解利也。如夹脾虚、肾虚、亡血诸虚证，则以治
邪为主，养正为辅。盖疫邪最易伤正，故不可养正遗邪
也。如夹疝、哮、心胃痛诸旧病，则但治疫邪，旧病自已。盖旧病乃新邪所迫而发也。
疫邪夹杂疝气，表现为阴囊及少腹部牵引疼痛，这完全是疝气的证候，应当依据辨别气色、神态、脉象、舌苔的方法来诊断。一旦确认有疫邪存在，就不必专门治疗疝气，只需治疗疫邪，疝气自然就会消除。如果按照常规治疗疝气的方法，使用吴茱萸、肉桂、附子、小茴香等燥热性质的药物，轻症会转变为阴囊痈肿，重症则会演变为呃逆、干呕、四肢厥冷、深度昏迷而无法救治。
时行疫病兼有心胃疼痛的，在疼痛发作时，观察其气色、神态、脉象、舌苔。如果发现有疫邪特征，只治疗时行疫病，即使患者平时是因受寒而引发心胃痛，此时也只需针对热邪进行治疗。这是因为疫邪客居在募原（半表半里之膜原），传变至太阴经，从而诱发了心胃痛的旧疾。在达原饮中加入木香、苍术，以疏通郁滞的疫邪，使其透发于体表，疼痛自然停止。如果误认为是普通的心胃痛，使用肉桂、附子、干姜、吴茱萸，必然导致病情危重。
哮喘是肺脏素来有痰火蕴结，一旦感受疫邪，湿热之气同气相求进入肺部，诱发哮喘。遇到这种情况，应当观察其气色、神态、脉象、舌苔，如果有疫邪，就只治疗疫邪，哮喘自然消除。在治疗疫邪的药物中加入贝母、瓜蒌、淡豆豉、桑白皮，疫邪和哮喘同时解除，治疗方法更为精密。以上几条，凡是说“兼”的，是指疫邪兼夹其他外邪，两种邪气都是从外部侵入的。凡是说“夹”的，是指疫邪夹杂内部疾病，是内外合病。两种邪气同时发作，以疫邪为重，其他邪气为轻，所以只需略微兼顾治疗其他邪气，病就能解除。两种邪气夹发，如夹杂水湿、食积、瘀血、气滞、痰浊等实邪，则以治疗夹邪为先，治疗疫邪为后。因为清除了夹邪，疫毒才能得以透达，只有透达了才能发生传变，只有发生传变才能顺利解利。如果夹杂脾虚、肾虚、失血等各种虚证，则以治疗邪气为主，扶正养正为辅。因为疫邪最容易损伤正气，所以不能因为扶正而遗留邪气。如果夹杂疝气、哮喘、心胃痛等旧病，则只需治疗疫邪，旧病自然痊愈。因为旧病是新感邪气逼迫而引发的。
When epidemic pathogens are complicated by hernia (Shàn, a condition characterized by pain in the scrotum and lower abdomen), there is pulling pain from the scrotum to the lower abdomen. This presents entirely as a hernia syndrome and should be differentiated according to the methods of observing Qi, complexion, spirit, pulse, and tongue coating. Once an epidemic pathogen is present, there is no need to treat the hernia specifically; simply treating the epidemic will cause the hernia to resolve spontaneously. If one follows the conventional method for treating hernia, using drying and warming herbs such as Evodiae Fructus (Wúyú), Cinnamomi Ramulus (Guì), Aconiti Lateralis Radix Preparata (Fù), and Foeniculi Fructus (Huíxiāng), mild cases may transform into scrotal abscess (Nángyōng), while severe cases may deteriorate into hiccups (Ènì), retching (Yuě), cold extremities (Jué), and deep coma (Chénhūn), becoming incurable.
In seasonal epidemics complicated by heart and stomach pain, during episodes of pain, observe the patient's Qi, complexion, spirit, pulse, and tongue coating. If signs of an epidemic are present, treat only the seasonal epidemic. Even if the heart and stomach pain usually arises from cold exposure, in this context, one must treat only the heat. This is because the epidemic pathogen lodges in the Mouyuan (Membrane Source) and transmits to the Taiyin channel, thereby triggering the chronic disease of heart and stomach pain. Add Costi Rhizome (Mùxiāng) and Atractylodis Rhizoma (Cāngzhù) to the Damoyin Decoction (Dámoyuán Yǐn) to open up the stagnant epidemic qi, allowing it to penetrate to the exterior, at which point the pain will cease. Mistaking this for ordinary heart and stomach pain and using Cinnamomi Ramulus (Guì), Aconiti Lateralis Radix Preparata (Fù), Zingiberis Rhizoma (Jiāng), or Evodiae Fructus (Yú) will inevitably lead to critical danger.
Asthma (Xiàochuǎn) stems from phlegm-fire previously existing in the Lung system. Upon contracting an epidemic pathogen, damp-heat qi enters the lungs following its kind, triggering asthma. In such cases, observe the Qi, complexion, spirit, pulse, and tongue coating. If an epidemic pathogen is present, treat only the epidemic, and the asthma will resolve spontaneously. Add Fritillariae Bulbus (Bèimǔ), Trichosanthis Fructus (Guālóu), Sojae Semen Praeparatum (Dànchǐ), and Morus Cortex (Sāngpí) to the anti-epidemic formula. This resolves both the epidemic pathogen and asthma simultaneously, employing a more precise method.
Regarding the above clauses: "Complicated by" (Jiān) refers to the epidemic pathogen accompanying other external pathogens, where both enter from outside. "Mixed with" (Jiā) refers to the epidemic pathogen mixed with internal diseases, representing an internal-external simultaneous onset. When two pathogens arise together, the epidemic is heavy and the other pathogen is light; thus, slightly addressing the other pathogen suffices to resolve the illness. When two pathogens mix, such as with water retention, food stagnation, blood stasis, qi stagnation, or phlegm-turbidity (real/excess pathogens), treat the mixed pathogen first and the epidemic pathogen second. Clearing the mixed pathogen allows the epidemic toxin to penetrate; penetration enables transmission; and transmission facilitates resolution. If mixed with deficiency syndromes such as Spleen deficiency, Kidney deficiency, or blood loss, treat the pathogen primarily and support the healthy Qi secondarily. Since epidemic pathogens easily damage the healthy Qi, one must not nourish the healthy Qi to the detriment of leaving the pathogen behind. If mixed with old diseases such as hernia, asthma, or heart and stomach pain, treat only the epidemic pathogen, and the old diseases will resolve themselves. This is because old diseases are triggered by the pressure of new pathogens.
