世之言疫者，将瘟疫二字读滑，随曰疫止有瘟而无寒也。岂知疫有三而瘟其一
焉。尚有寒疫、杂疫二者，而人自不体认耳。兹专说寒疫，吴又可言∶春夏秋三时，偶感暴寒，
但可谓感冒，不当另立寒疫之名固已，但感训触，冒训犯，系人不慎风寒自取之。至于当天气方温
热之时，而凄风苦雨骤至，毛窍正开，为寒气所束，众人同病，乃天实为之，故亦得以疫名也。
其症则头痛身痛身热，脊强恶寒拘急，无汗，（感冒所有。）或则往来寒热，气壅痰喘，咳嗽胸
痛，鼻塞声重，涕唾稠粘，咽痛齿痛，（俗云寒逼生火，感冒所无。）苏羌饮主之。（自定新方。）

十神等汤，诚诸路之应兵也。）

治疫瘴；防风能防御外风，随所引而至；陈皮利气而寒郁易解；姜可驱邪，葱能发汗，辅佐诸药，
以成厥功。四时风寒，皆能治疗，甚毋以药味平
浅而忽之。（惟不治瘟疫。）
如兼阳明症者，加白芷一钱；兼食积者，加炒麦芽、神曲各一钱；肉积者，加山楂一钱；风
痰气壅，涕唾稠粘，加前胡一二钱；咳嗽喘急，加杏仁一钱；（泡去皮、尖，研。）心腹膨胀，加姜

世人谈论疫病时，往往将“瘟疫”二字连读滑过，随即说疫病只有瘟邪而没有寒邪。哪里知道疫病分为三类，而瘟只是其中一种。还有寒疫、杂疫两种，只是人们自己未能仔细辨认罢了。这里专门论述寒疫。吴又可曾说：春夏秋三个季节，偶然感受暴寒，只能说是感冒，不应当另外设立寒疫的名称，这已经是对的。但是，“感”训释为触，“冒”训释为犯，是指人不慎风寒而自取其病。至于当天气正温热之时，凄风苦雨突然到来，毛孔正张开，被寒气束缚，众人同时患病，这是上天造成的，所以也可以称为疫。其症状表现为头痛、身痛、身热、脊背强直、恶寒、拘急、无汗（这些是感冒所具有的）。或者出现寒热往来、气壅痰喘、咳嗽胸痛、鼻塞声重、鼻涕唾沫稠粘、咽痛齿痛（俗话说是寒逼生火，这是感冒所没有的），用苏羌饮主治。（此为作者自定的新方。）
苏羌饮 （治疗四季寒疫，历来有奇效，屡试屡验。并治疗伤寒、伤风，可以替代麻黄汤、桂枝汤、青龙汤、羌活胜湿汤、十神汤等，确实是各路应敌的兵卒。）
紫苏（三钱） 羌活（二钱） 防风（一钱） 陈皮（一钱） 淡豆豉（二钱） 葱白（数段）
加水煎煮服用，若无效再服。初觉不适时，迅速服用必能痊愈，迟则会产生变证。
此方属于足太阳经的药物。紫苏温中达表，解散风寒；羌活直入本经，治疗太阳经的各种症状；淡豆豉解肌发汗，兼治疫瘴；防风能防御外风，随引经药到达病所；陈皮理气，使寒郁容易解除；生姜可驱邪，葱白能发汗，辅助诸药，以成就功效。四季风寒，皆能治疗，千万不要因为药味平淡浅近而忽视它。（唯独不治瘟疫。）
如果兼有阳明经症状的，加白芷一钱；兼有食积的，加炒麦芽、神曲各一钱；肉食积滞的，加山楂一钱；风痰气壅，鼻涕唾沫稠粘，加前胡一二钱；咳嗽喘急，加杏仁一钱（泡过去皮、尖，研碎）。心腹胀满，加姜炒厚朴一钱；胸膈闷寒，加炒枳壳五六分；呕逆恶心，酌情加藿香、制半夏、生姜各一钱；年高体弱、虚怯者，加人参一钱；阴虚血虚者，加熟地黄三钱，当归一钱；脾虚者、中气不足者，加人参、白术各一钱。此方为发汗散邪之剂，所以不使用柴胡。若现出少阳经症状，应当另作主张，使用和解的药剂。（锦志注。）

* Changshan (Dichroae Radix, 1 qian)
* Xiaomai (Tritici Venirei Fructus Immaturus, 3 qian)

* Caoguo (Amomi Fructus Rotundus, 1 piece)
Soak in one bowl of hot yellow wine overnight. Take facing east at Wugeng. Cover with a blanket and sleep; upon waking from the effects of the wine, the illness will be cured.
Another prescription: Changshan (Dichroae Radix), Binglang (Arecae Semen), and Gancao (Glycyrrhizae Radix et Rhizoma) each 3 qian, with 100 Heidou (Phaseoli Vulgaris Semen). Decoct in water and take. Named Changbing Caodou Decoction.
(Caused by consuming five pungent foods after recovery from febrile disease.)
Jiyu (Cyprini Carassii Corpus): Use crucian carp to prepare food, consume until finished.
Pingxi San
* Zibeifuping (Spirodherae Herba, sun-dried, 1 qian)
* Xijiaoxie (Rhinocerotis Cornu, sliced, 5 fen)
* Goutenggou (Uncariae Ramulus cum Uncis, 30-70 hooks)
Grind into powder. Take 1.5 qian per dose, mixed with honey water. Administer three consecutive doses until sweating occurs. (If preparing larger quantities, double the dosage of all herbs.)
(Tone 'ni', referring to small insects.)
Taozhi Jian: Boil peach branches to make a concentrated decoction. Hold in the mouth. For sores in the lower body, insert it locally.
(Also treats plague.)
Dihé Jian
* Shengdi (Rehmanniae Radix; use dried if fresh is unavailable)
* Bohe (Menthae Haplocalycis Herba, equal parts)
Pulverize thoroughly. For dried herbs, extract juice with water. Add a small amount of Shexiang (Moschus). Mix with Jinghua Water (well water drawn at dawn) and take orally. Stop taking when a cooling sensation is felt in the epigastrium; do not continue. In severe cases, one dose yields results.
Take one bunch of Congbai (Allii Fistulosi Bulbus) and three bowls of water. Cook until done, drink the broth, and consume all the scallions to induce sweating.
Honghua Wine: Boil Honghua (Carthami Flos) in yellow wine. Drink two or three cups.
People discussing epidemics often slur the term "Wenyi" (Plague/Epidemic) and claim that epidemics consist only of warm pathogens without cold. They fail to realize that epidemics are divided into three categories, with Wen (Warm) being just one. There remain Cold Epidemic (Hanyi) and Mixed Epidemic (Zayi), which people simply fail to recognize. Here, we specifically discuss Cold Epidemic. Wu Keyi stated: In spring, summer, and autumn, occasional exposure to sudden cold should merely be called common cold (Ganmao) and not given a separate name for Cold Epidemic. This is correct because "Gan" implies contact and "Mao" implies violation, suggesting the illness is self-inflicted due to negligence against wind and cold. However, when the weather is warm but sudden cold winds and bitter rains arrive while pores are open, causing everyone to fall ill simultaneously under the constraint of cold air, this is caused by Heaven. Thus, it can also be named an epidemic.
Symptoms include headache, body pain, fever, stiffness of the spine, aversion to cold, rigidity, and absence of sweating (symptoms present in common cold). Alternatively, there may be alternating chills and fever, qi stagnation with phlegm and wheezing, cough, chest pain, nasal congestion with heavy voice, thick sticky sputum and nasal discharge, sore throat, and toothache (commonly said to be fire generated by cold constraint, symptoms absent in common cold). These are treated primarily with Suqiang Yin (Author's new formula).
Suqiang Yin (Treats cold epidemics in all four seasons with remarkable efficacy, repeatedly tested and verified. Also treats Taiyang Shanghan and Wind-Cold invasion; can replace Mahuang Tang, Guizhi Tang, Qinglong Tang, Qianghuo Shengshi Tang, and Shishen Tang; truly a versatile army for various fronts.)
* Zisu (Perillae Folium, 3 qian)
* Qianghuo (Notopterygii Rhizoma et Radix, 2 qian)
* Fangfeng (Saposhnikoviae Radix, 1 qian)
* Chenpi (Citri Reticulatae Pericarpium, 1 qian)
* Danshi (Sojae Preparata, 2 qian)
* Congbai (Allii Fistulosi Bulbus, several segments)
Decoct in water and take. If ineffective, take again. Take promptly at the first sign of discomfort for certain cure; delay leads to complications.
This formula acts on the Foot-Taiyang channel. Zisu warms the interior and reaches the exterior, dispersing wind-cold; Qianghuo enters its own channel directly, treating various Taiyang symptoms; Danshi releases the muscle layer and induces sweating, also treating miasma; Fangfeng defends against external wind, following the guiding herbs to the site; Chenpi regulates qi, making cold stagnation easier to resolve; Shengjiang (Zingiberis Rhizoma Recens) drives out evil, and Congbai induces sweating, assisting the other herbs to achieve success. It treats wind-cold in all four seasons; do not neglect it because the herbs seem mild and simple. (It does not treat Warm Plague.)
If accompanied by Yangming symptoms, add Baizhi (Angelicae Dahuricae Radix) 1 qian; if accompanied by food stagnation, add Chao Maiya (Hordei Fructus Germinatus) and Shenqu (Massa Medicata Fermentata) each 1 qian; for meat stagnation, add Shanzha (Crataegi Fructus) 1 qian; for wind-phlegm qi stagnation with thick sticky sputum, add Qianhu (Peucedani Radix) 1-2 qian; for cough and urgent wheezing, add Xingren (Armeniacae Semen Amarum) 1 qian (soaked, skin and tip removed, ground); for abdominal distension, add Jiangchao Houpo (Magnoliae Officinalis Cortex processed with ginger) 1 qian; for chest oppression and cold, add Chao Zhike (Aurantii Fructus) 5-6 fen; for vomiting and nausea, add Huoxiang (Agastaches Herba), Zhibanxia (Pinelliae Rhizoma Praeparatum), and Shengjiang each 1 qian as appropriate; for the elderly, weak, or deficient, add Renshen (Ginseng Radix) 1 qian; for yin deficiency and blood deficiency, add Shudi (Rehmanniae Radix Preparata) 3 qian and Danggui (Angelicae Sinensis Radix) 1 qian; for spleen deficiency or insufficient middle qi, add Renshen and Baizhu (Atractylodis Macrocephalae Rhizoma) each 1 qian. This is a diaphoretic formula, hence Chaihu (Bupleuri Radix) is not included. If Shaoyang symptoms appear, one must adopt a different approach and use harmonizing agents. (Note by Jin Zhi.)
