（附论）
人们生活在天地之间，禀受阴阳之气。气机调和则身体安康，气机逆乱则发生疾病。因此，一年之中，如果节气失调，寒暑失常，都会形成疫疠之气，人体感受这种邪气而发病，所以称为疫疠。其症状不论年龄大小，大体都相似，民间又称之为“天行”。这类疾病与时气、温热等病证相似，治疗时各自根据具体证候，制定相应的方剂来治疗。
又有诗云：四季的疫疠发作难以预料，老人和幼儿的调理总是一样的。夏季的病责治于心，冬季的病责治于肾，长夏（季夏）责治于脾，秋季责治于肺，春季责治于肝。
又有论述说：春季感受疫疠清冷之气，用升麻葛根汤、解肌汤；夏季感受寒邪，用理中汤、麝香汤、半夏桂甘汤；秋季感受热邪，用白虎加苍术汤；出现发黄黄疸者，用茵陈五苓散；冬季感受暖邪，用葳蕤汤。四季通用的有败毒散、升麻葛根汤。土气没有固定的运行方向，因火而得名（指长夏属土，寄旺于四季之末，或指湿热），应当根据具体症状来选取方药。
方剂
牛黄七宝膏：治疗伤寒时疫，热毒暑病，心胸痞塞，或者出现发黄发斑，狂躁迷闷，以及经过多次攻下取效不佳，蕴积的毒邪滞留引起潮热。
药材及用量：牛黄（五分）、龙脑（五分）、麝香（五分）、朱砂（二钱五分）、轻粉（五钱以上，均需研磨）、白面（五钱）、寒水石（烧至通红，三两半）。
制法与用法：将上述药物共同研磨均匀，滴水调和制成二十丸。每次服用一丸，用清水化开服用。小儿服用半丸。不限时间。
圣散子：治疗伤寒时行疫疠，风温湿温，不问是阴证阳证两感，还是表里未辨明，或者是外热内寒、外寒内热，出现头项腰脊拘急，发热恶寒，肢节疼痛，呕吐逆气喘咳，鼻塞声重，以及饮食生冷，损伤胃脘导致满闷，腹胁胀痛，心下结痞，手足逆冷，肠鸣泄泻，水谷不消化，时常自汗出，小便不利。因为看到苏东坡先生对它的注述，其功效不可胜数。过去在杭州、黄州时，那年瘟疫大流行，全城人都患此病，病情危重无法救治。每次使用圣散子，不问是阴证还是阳证两感，无论男女，病情即使危重，连续服用几剂，就能汗出气通，连续服用后痊愈。药性微热，但阳毒发狂的人，入口便觉得清凉。这药大概不能用常理来衡量。如果时疫流行，不问老幼贵贱，每人各饮一盏，那么时气百病都不会产生，真是济世卫家的宝物啊。这个方子是巢君家世代珍视的，治疗这种疾患有百次不失一次的疗效。我贬谪居住在黄州时，连年发生大瘟疫，所保全救活的人，不可胜数。巢君非常保密这个方子，偶然泄露出来，传给了蕲水的庞君。当时庞君以医术闻名于世，又擅长著书，所以把这个方子传授给他，并且让巢君与此方一同不朽。噎膈症是气停胸膈，想打嗝反逆却声音出不来，圣散子主治。可以加柿蒂煎服。

(Attached Discussion)
Humans live between heaven and earth, inheriting Qi from Yin and Yang. When Qi is harmonious, there is health; when Qi is rebellious, disease occurs. Therefore, within a year, if the solar terms are disharmonious and cold and heat deviate from their proper seasons, all these form the Qi of epidemics (Yi Li). Contracting this pathogen causes disease, hence it is called epidemic. Its symptoms are generally similar regardless of age or stature, and it is commonly known as "Tian Xing" (Heavenly Transmission). This illness is similar to diseases such as seasonal Qi (Shi Qi) and warm-heat (Wen Re). Treatment varies according to the specific syndrome, using formulas tailored to the condition.
There is also a poem stating: "Epidemics in the four seasons are hard to predict; regulation for the old and young is generally the same. Summer ailments target the Heart, winter ailments target the Kidney; late summer targets the Spleen, autumn targets the Lung, and spring targets the Liver."
Another discussion states: For spring epidemics contracted with clear/cold Qi, use Shengma Gegen Tang (Cimicifugae et Puerariae Decoction) and Jie Ji Tang (Muscle-Releasing Decoction). For summer contraction of cold, use Lizhong Tang (Regulate the Middle Decoction), Shexiang Tang (Musk Decoction), and Banxia Guigan Tang (Pinellia, Cinnamon Twig, and Licorice Decoction). For autumn contraction of heat, use Baihu Jia Cangzhu Tang (White Tiger plus Atractylodes Decoction); for those presenting with jaundice, use Yinchin Wuling San (Artemisiae Scopariae and Five-Ingredient Powder with Poria). For winter contraction of warmth, use Ruiyu Tang (Jade Reed Decoction). For all four seasons, Baidu San (Deficiency-Resolving Powder) and Shengma Gegen Tang are universally applicable. Earth Qi has no fixed direction but is named due to Fire (referring to damp-heat or late summer); one should select prescriptions based on symptoms.
Formulas
Niuhuang Qibao Gao (Seven-Treasure Bull Gallstone Ointment): Treats Shanghan (Cold Damage) and seasonal epidemics, heat-toxin and summerheat diseases, chest and epigastric stuffiness, yellow jaundice with macules, mania, restlessness, confusion, and chronic accumulation of toxins causing tidal fever unresponsive to repeated purgation.
Ingredients: Niuhuang (Bovis Calculus, 5 fen), Longnao (Borneolum Syntheticum, 5 fen), Shexiang (Moschus, 5 fen), Zhusha (Cinnabaris, 2 qian 5 fen), Qingfen (Calomelas, >5 qian, all ground), Baifan (Alumen, 5 qian), Hanshuishi (Aqua Marina calcined to redness, 3 liang 5 qian).
Preparation and Administration: Grind all ingredients uniformly, mix with water drops to form 20 pills. Take one pill per dose, dissolved in clear water. Children take half a pill. Take at any time.
Shengsan Zi (Holy Scattered Seeds): Treats Shanghan, seasonal epidemics, Fengwen (Wind-Warmth), and Shiwen (Damp-Warmth). Applicable regardless of whether it is Yin-Yang dual infection or exterior-interior differentiation is unclear, or if there is exterior heat with interior cold, or exterior cold with interior heat. Symptoms include stiffness and spasm of the head, neck, waist, and spine; fever and aversion to cold; pain in limbs and joints; vomiting, regurgitation, wheezing, and coughing; nasal congestion and heavy voice; consumption of raw/cold food leading to epigastric fullness; abdominal and hypochondriac distension and pain; epigastric knotting and stuffiness; cold extremities; borborygmus and diarrhea; undigested food and water; spontaneous sweating; and difficult urination. Based on Mr. Dongpo's annotations, its efficacy is beyond description. Previously in Hangzhou and Huangzhou, during a severe epidemic where the whole city fell ill and many died critically, Shengsan Zi was used successfully regardless of Yin/Yang dual infection or gender. Even in critical cases, continuous doses led to sweating, free Qi flow, and recovery. The formula is slightly warm, yet brings a cooling sensation even to patients with Yang toxicity and mania. It defies common logic. During epidemics, anyone, old or young, rich or poor, drinking one cup prevents seasonal diseases. It is truly a treasure for saving lives and protecting families. Master Chao treasured this formula for generations, achieving near-perfect success rates. While I was demoted to Huangzhou, annual epidemics claimed many lives, but countless were saved by this formula. Master Chao kept it secret until he accidentally revealed it to Pang Jun of Qishui, a renowned physician and author, ensuring the formula's immortality alongside Master Chao. For Ye syndrome (Qi stagnation in the chest/diaphragm, desire to belch but unable to produce sound), Shengsan Zi is indicated. Add Shi Di (Kaki Calyx) to the decoction.

For chronic dampness causing leg/back pain and difficulty walking, decoct with wine.
