凡感四时六淫之邪。而病身热者。今人悉以伤寒名之。是伤寒者。热病之总名也。
其因于寒者。自是正病。若夫因暑因湿。因燥因风。因六淫之兼气。或非时之戾气。发为风温、湿温、
温病、寒疫等症。皆类伤寒耳。病热虽同。所因各异。不可概以伤寒法治之。且伤寒正病绝少。类症尤多。
苟不辨明。未免有毫厘千里之差。准绳独以类症弁诸首。亦以辨症为先务也。用仿其意。首列类症。凡
同伤寒之例而治者十一症。不同者八症。共一十九症。庶临症者得其先务云。

伤寒奥旨）以上八症。不同伤寒施治。
按伤寒类症虽多。惟温热关于伤寒为尤重。以今之伤寒。大半属于温热也。且
治法与伤寒不侔。伤寒入足经。而温邪兼入手经。伤寒宜表。而温邪忌汗。伤寒药宜辛温。而温邪
药宜辛凉。苟不辨明。必有误治。故兹集特参以温热立论。而以温热之法为兼治焉。凡列于太阳症内。
是伤寒正病。而列于阳明少阳经中。其症都兼温热。盖少阳木火之原。阳明湿热之薮。其风温温热之
邪。自是同气之感。他如霍乱香港脚等症。治法各备本门。
邵评∶此数句。分别伤寒温热之来路不同。治法用药之各异。大宜着眼。
凡是感受四季六淫之邪，而出现身体发热的病症，现在的人全都称之为伤寒。因此，伤寒是热病的总称。
其中因寒邪引起的，属于正病（典型伤寒）。至于因暑、因湿、因燥、因风，或因六淫兼夹之气，或非时节的戾气，引发风温、湿温、温病、寒疫等症候的，都属于类伤寒。虽然发病时的热象相同，但致病原因各异，不能一概用治疗伤寒的方法来对待。况且典型的伤寒极少，类似的症状却很多。如果不加以辨别，难免会有毫厘之差导致千里之谬。《医宗金鉴·伤寒心法要诀》（简称《准绳》）特意将类症放在卷首，也是把辨证作为首要任务。我仿照这个意图，首先列出类症。凡同伤寒一样治疗的有十一症，不同者有八症，共一十九症，希望临证时能抓住首要关键。
冬温、春温、寒疫、热病、湿温、风温、霍乱、痉、湿痹、风湿、中暍（以上十一症同伤寒施治）
伤食、痰饮、香港脚（脚气）、内痈、虚烦、蓄血、黄耳、赤胸（以上八症不同伤寒施治）
从霜降节气以后，天气寒冷，感受寒邪而生病的，是伤寒。
霜降以后，应当寒冷却不寒冷，反而温暖，因而衣着单薄，导致感受寒邪而生病的，是冬温。
邵评：冬温，是指冬季受邪而立即发病的病证。症状多表现为外有寒邪束表，内有郁热（客寒包火）。
春季天道和暖，有人出现高热、口渴，且不恶寒的，是温病。如果用辛温药物发汗，就会造成坏病。如果时令仍然寒冷，冰雪未消融，感受寒邪而生病的，也属于伤寒。
邵评：春温病有两种情况。一是冬季感受寒邪没有立即发病，到了春天伏邪发热，称为春温；二是春季气候过热，外感时令邪气而发病，这是感邪即发的春温。辨证方法：伏气春温，初起只发热不恶寒且口渴，这是由内向外发的；感而即发的春温，初起微恶寒，后来只发热不恶寒，这是由肺卫受邪所致。
三月以后，八月以前，天道若有暴寒，感受寒邪而生病的，是时行寒疫。这种寒疫也属于伤寒范畴，不能用治疗正疫的方法来处理。
夏至以后，时令炎热，有人出现高热、烦躁、口渴，且不恶寒的，是热病。热病与中暑相似，但热病脉象盛大，中暑脉象虚弱。
邵评：热病和中暑两病，都发生在夏天，所以必须通过脉象来辨别。热病脉象盛大，大而有力；中暑脉象虚弱，弦而芤细。
夏季患病，头痛、谵语、自汗，身体不甚热，两小腿逆冷，四肢沉重，胸腹部胀满且口渴的，是湿温。
此人平时常受湿气困扰，又因中暑，湿热相互搏结，所以发生此病。不可使用发汗法。
头痛、身热、自汗，与伤寒相似，但寸关尺三部脉俱浮，身体沉重、神情沉默、只想睡觉、鼻鼾、语言困难、四肢不能收持的，是风温。不可发汗。
患病呕吐，腹痛泄泻，恶寒发热，或吐或利，并伴有发热的，是霍乱。
身体发热，足部寒冷，头项强直紧急，恶寒时头部发热、面色红赤，目睛脉络红赤，只有头部摇动，突然牙关紧闭，角弓反张的，是痉病。
太阳病，发热无汗，反而恶寒的，为刚痉。发热有汗，不恶寒的，为柔痉。
邵评：根据有汗无汗、恶寒不恶寒，来区分刚痉和柔痉。刚痉属寒，柔痉属风。
太阳病，关节疼痛且烦躁，脉象沉而细，这叫做湿痹。其征候是小便不利，大便反而通畅，只应当通利小便。
病人全身疼痛，发热在傍晚加重，脉象浮而濡软，额头微微出汗，不想脱去衣被，或者四肢浮肿，这是风湿。不可大汗出。如果汗出过多，风邪去了但湿邪不去，只要让患者微微似有汗出的样子，风湿就能一起去除。
太阳中热，就是中暍。发热恶寒，身体沉重且疼痛，出汗且口渴，脉象微弱。以上十一症，同伤寒施治。
头痛发热，与伤寒相似，但身体不痛，右关脉短滑，左脉平和的，是伤食。中脘穴部位必然痞闷堵塞。也有停食兼感寒邪的情况，此时人迎脉和气口脉都大。
憎寒发热，恶风自汗，胸部胀满，气上冲咽喉，呼吸不畅，与伤寒相似，但头部不痛，或者有时痛有时不痛。
脉象紧但不大的，是痰饮。痰在上焦，则寸口脉沉滑，或沉伏。痰在中焦，则右关脉滑大。如果有气郁，则脉沉而滑。夹带食积，则脉短而滑。凡是脉弦滑的，是有痰饮。偏弦的脉主饮邪。沉弦的脉，是有悬饮和内痛。
发热、憎寒、头痛、肢节痛、呕吐恶心，与伤寒相似，但疼痛起始于脚部，脚膝肿痛，两小腿肿胀饱满，或者枯瘦细小，大便干结的，是香港脚（脚气）。
脉浮数、发热、洒淅恶寒，如果有疼痛部位，饮食正常的，是内痈。胸中隐隐作痛，振寒，脉数，咽干但不渴，口中咳嗽，时常吐出浑浊腥臭的唾沫，时间久了吐脓的，是肺痈。小腹重坠，皮肤紧张，按压疼痛，小便频数像淋病，时间久了必排脓血，时时出汗，又恶寒，脉滑而数的，是肠痈。胃脘部隐隐作痛，手不可靠近，胃脉沉细，人迎脉逆而盛大的，是胃脘痈。
烦热与伤寒相似，但脉不浮紧，头不疼，身不痛，不恶寒。或者心烦时头也痛，心烦止则头痛止的，是虚烦。
发热如伤寒，但此人曾从高处置坠落，扑打损伤，或者盛怒呼叫，或者强力负重，不久就发病，小便自利，口不太渴，按压胸胁脐腹间有痛点，或者手不可靠近的，是蓄血。（以上出自《准绳》）
发热恶寒，脊背强直，有点像痉病状，耳朵里刺刺作痛的，是黄耳。这属于太阳经，风邪入肾经。用荆防败毒散，加蝉蜕、黄芩、赤芍、紫荆皮。寒邪重的，用小续命汤，加白附子、天南星、天麻。外治法：用苦参磨水滴入耳中。
发热恶寒头痛，似伤寒，但胸膈部红肿疼痛的，是赤胸。属于少阳风热。用荆防败毒散，加黄芩、黄连、瓜蒌、玄参、赤芍、升麻、紫荆皮，大便燥实加大黄。外治法：用三棱针刺出其瘀血，则肿消痛止。（黄耳、赤胸出自《伤寒奥旨》）以上八症，不同伤寒施治。
按：伤寒类症虽然多，惟独温热病与伤寒的关系最为重要。因为现在的伤寒，大半属于温热范畴。而且治疗方法与伤寒不同。伤寒传入足经，而温邪兼入手经；伤寒宜解表，而温邪忌发汗；伤寒药宜辛温，而温邪药宜辛凉。如果不辨别清楚，必然会导致误治。所以本集特别参考温热理论立论，并将温热的方法作为兼治手段。凡是列在太阳症内的，是伤寒正病；而列在阳明、少阳经中的，其症状都兼有温热。盖因少阳为木火之源，阳明为湿热之薮，风温和温热的邪气，自然是同气相求。其他如霍乱、香港脚等症，治疗方法各自备载在本门之中。
邵评：这几句话，分别指出了伤寒和温热病的来源不同，治疗方法和用药的差异，非常值得注意。
Whenever one contracts the pathogenic factors of the Six Excesses (Liu Yin) of the four seasons and develops fever, people nowadays generally call it Shanghan (Cold Damage). Therefore, Shanghan is the general term for heat diseases.
Among these, those caused by cold are considered Zheng Bing (typical Shanghan). As for those caused by summerheat, dampness, dryness, or wind, or by combined influences of the Six Excesses, or by pestilential qi occurring out of season, which manifest as symptoms such as Fengwen (Wind-Heat), Shiwēn (Damp-Heat), Wenbing (Warm Disease), and Hanyi (Cold Epidemic), they all belong to Lei Shanghan (Shanghan-like diseases). Although the presentation of fever is similar, the etiologies differ; thus, they cannot be treated uniformly with methods for typical Shanghan. Moreover, typical Shanghan cases are rare, while Shanghan-like presentations are numerous. Failure to distinguish them clearly may lead to significant errors in treatment. *Yi Zong Jin Jian* (Golden Mirror of Medicine) places Shanghan-like diseases at the beginning of its volume, emphasizing that differentiation of syndromes is the primary task. I have followed this intent and listed Shanghan-like diseases first. There are eleven syndromes treated similarly to Shanghan and eight treated differently, totaling nineteen syndromes, so that practitioners may grasp the primary tasks when encountering clinical cases.
Winter Warmth, Spring Warmth, Cold Epidemic, Heat Disease, Damp-Heat, Wind-Heat, Huoluan (Cholera-like disease), Jing (Spasm), Shi Bi (Damp Bi), Feng Shi (Wind-Damp), Zhong Yue (Summerheat Strike) (The above eleven syndromes are treated similarly to Shanghan)
Food Retention, Phlegm, Xianggangjiao (Foot Qi/Charcot-Marie-Tooth like condition), Nei Yong (Internal Abscess), Xu Fan (Deficiency Restlessness), Chu Xue (Blood Stasis), Huang Er (Yellow Ear), Chi Xiong (Red Chest) (The above eight syndromes are treated differently from Shanghan)
After the Frost Descent solar term, when the weather is cold, contracting cold pathogens and becoming ill constitutes Shanghan.
After the Frost Descent solar term, if the weather should be cold but remains warm instead, leading to illness due to thin clothing and subsequent contraction of cold, this is Winter Warmth.
Shao's Commentary: Winter Warmth refers to a disease contracted in winter that manifests immediately. The symptoms often present as external cold binding the exterior with internal heat (Ke Han Bao Huo).
In spring, when the heavenly climate is mild and warm, if a person presents with high fever, thirst, and no aversion to cold, it is Wenbing (Warm Disease). Using acrid-warm herbs to induce sweating would result in a complicated disease (Huai Bing). If the seasonal climate remains cold and ice has not melted, contracting cold and becoming ill is also classified as Shanghan.
Shao's Commentary: There are two types of Spring Warmth. One type involves cold pathogens contracted in winter that do not manifest immediately but cause fever in spring due to latent qi; this is named Spring Warmth. The other type occurs when the spring climate is excessively hot, and the person contracts seasonal pathogens causing immediate onset; this is Spring Warmth manifesting immediately after contraction. Differentiation method: For Spring Warmth due to latent qi, initial presentation features only fever without aversion to cold and thirst, indicating emergence from within to the exterior. For Spring Warmth manifesting immediately after contraction, initial presentation features slight aversion to cold, followed by only fever without aversion to cold, indicating invasion via the Lung and Defensive levels.
Between the third and eighth lunar months, if sudden cold occurs in the climate, contracting cold pathogens and becoming ill is called Shixing Hanyi (Seasonal Cold Epidemic). This Cold Epidemic also falls under the category of Shanghan and should not be treated as a typical epidemic disease.
After the Summer Solstice, during the hot season, if a person presents with high fever, restlessness, thirst, and no aversion to cold, it is Re Bing (Heat Disease). Heat Disease resembles Zhong Shu (Heat Stroke), but the pulse in Heat Disease is vigorous, whereas in Heat Stroke it is deficient.
Shao's Commentary: Both Heat Disease and Heat Stroke occur in summer, so they must be differentiated by pulse. Heat Disease presents with a vigorous, large, and forceful pulse; Heat Stroke presents with a string-taut, cun-kou fine, and deficient pulse.
In summer, if a patient presents with headache, delirium, spontaneous sweating, body not significantly hot, reverse coldness in both calves, heaviness in the limbs, fullness in the chest and abdomen, and thirst, it is Shi Wen (Damp-Heat).
This individual has frequently been injured by dampness and subsequently struck by summerheat; the dampness and heat contend with each other, causing this disease. Sweating methods should not be used.
Headache, body heat, and spontaneous sweating resemble Shanghan, but the pulse at the cun, guan, and chi positions on both hands is floating. The body feels heavy, the person is silent, desires sleep, snores, has difficulty speaking, and cannot control the limbs. This is Feng Wen (Wind-Heat). Sweating methods should not be used.
Illness presenting with vomiting, abdominal pain, diarrhea, aversion to cold and fever, alternating between vomiting and purging, accompanied by fever, is Huoluan (Cholera-like disease).
Body heat, cold feet, stiffness and tension in the head and neck, aversion to cold with simultaneous heat in the head and red face, redness of the eye vessels, isolated head tremor, sudden lockjaw, and opisthotonos constitute Jing (Spasm).
In Taiyang disease, fever without sweating and paradoxical aversion to cold indicates Gang Jing (Stiff Spasm). Fever with sweating and no aversion to cold indicates Rou Jing (Flexible Spasm).
Shao's Commentary: Gang Jing and Rou Jing are distinguished by the presence or absence of sweating and aversion to cold. Gang Jing is associated with cold, while Rou Jing is associated with wind.
In Taiyang disease, joint pain accompanied by irritability and a deep, fine pulse is named Shi Bi (Damp Bi). Its signs include difficult urination and loose stools; treatment should focus on promoting diuresis.
A patient suffering from generalized body pain, fever worsening in the late afternoon, a floating and soggy pulse, slight sweating on the forehead, reluctance to remove clothes, or edema in the four limbs, suffers from Feng Shi (Wind-Damp). Profuse sweating should be avoided. If sweating is excessive, the wind pathogen leaves but the dampness remains. Only by inducing a slight, continuous perspiration can both wind and dampness be expelled.
Taiyang Zhong Re (Heat Strike in Taiyang) refers to Zhong Yue (Summerheat Strike). Symptoms include fever, aversion to cold, heaviness and pain in the body, sweating, thirst, and a weak pulse. The above eleven syndromes are treated similarly to Shanghan.
Headache and fever resemble Shanghan, but the body does not hurt. The right guan pulse is short and slippery, while the left pulse is peaceful. This indicates Food Retention. There will likely be stuffiness and oppression in the Zhongwan area. In some cases, food retention is combined with cold contraction, resulting in both Renying and Qikou pulses being large.
Avulsion from cold, fever, aversion to wind, spontaneous sweating, chest fullness, qi rushing up to the throat causing dyspnea, resembling Shanghan but without headache, or with intermittent headache. A tight pulse that is not large indicates Phlegm. If phlegm is in the Upper Jiao, the cunkou pulse is deep and slippery, or deep and hidden. If phlegm is in the Middle Jiao, the right guan pulse is slippery and large. With qi stagnation, the pulse is deep and slippery. With food retention, the pulse is short and slippery. Generally, a string-taut and slippery pulse indicates phlegm-fluids. A predominantly string-taut pulse indicates fluid retention. A deep and string-taut pulse indicates Xuan Yin (hanging fluid) and internal pain.
Fever, avulsion from cold, headache, joint pain, vomiting, and nausea resemble Shanghan, but the pain originates in the feet, with swelling and pain in the ankles and knees, fullness or emaciation of the calves, and hard stools. This is Xianggangjiao (Foot Qi).
A floating and rapid pulse, fever, shivering chills, presence of painful areas, and normal appetite indicate Nei Yong (Internal Abscess). Hidden pain in the chest, chills, rapid pulse, dry throat without thirst, coughing up turbid, foul-smelling sputum, and eventual expectoration of pus over time indicate Fei Yong (Lung Abscess). Heaviness in the lower abdomen, tense skin, tenderness upon pressure, frequent urination resembling strangury, eventual passage of pus and blood in stool, occasional sweating, aversion to cold, and a slippery and rapid pulse indicate Chang Yong (Intestinal Abscess). Hidden pain in the epigastrium, extreme tenderness where touch is unbearable, a deep and fine stomach pulse, and a reversed and vigorous Renying pulse indicate Wei Wan Yong (Epigastric Abscess).
Restless heat resembling Shanghan, but with a pulse that is not floating and tight, no headache, no body pain, and no aversion to cold. Or, headache occurs only when restlessness is present and ceases when restlessness subsides, indicates Xu Fan (Deficiency Restlessness).
Fever resembling Shanghan, but the patient has suffered a fall from height, blunt trauma, intense anger with shouting, or strenuous labor, followed shortly by illness. Urination is free, thirst is minimal, and there is tenderness in the chest, hypochondrium, umbilicus, or abdomen, or extreme tenderness to touch. This is Chu Xue (Blood Stasis). (Above sourced from *Yi Zong Jin Jian*)
Fever, aversion to cold, spinal rigidity, resembling spasm, with stinging pain in the ears, is Huang Er (Yellow Ear). This belongs to the Taiyang channel, with wind entering the Kidney meridian. Use Jing Fang Bai Du San (Schizonepeta and Saposhnikovia Decoction) plus Chan Tui (Cicada Slough), Huang Qin (Scutellaria Root), Chi Shao (Red Peony Root), and Zi Jing Pi (Bark of Cinnamomum Camphora). For severe cold pathogens, use Xiao Xu Ming Tang (Minor Continuation of Life Decoction) plus Bai Fu Zi (Typhonii Rhizoma), Tian Nan Xing (Arisaema Cum Bile), and Tian Ma (Gastrodiae Rhizoma). External treatment: grind Ku Shen (Sophora Root) with water and drip into the ear.
Fever, aversion to cold, headache, resembling Shanghan, but with redness, swelling, and pain in the chest and diaphragm, is Chi Xiong (Red Chest). This belongs to Shaoyang Wind-Heat. Use Jing Fang Bai Du San plus Huang Qin, Lian Qiao, Gua Lou (Trichosanthes Fruit), Yuan Shen (Scrophulariae Radix), Chi Shao, Sheng Ma (Cimicifugae Rhizome), Zi Jing Pi, and Da Huang (Rhei Radix et Rhizoma) if there is dry stool and excess. External treatment: prick with a three-edged needle to release blood, which will reduce swelling and stop pain. (Huang Er and Chi Xiong sourced from *Shanghan Ao Zhi*) The above eight syndromes are treated differently from Shanghan.
Note: Although there are many Shanghan-like syndromes, Wenre (Warm-Thermal) diseases are particularly important in relation to Shanghan. Most contemporary Shanghan cases belong to the Warm-Thermal category. Furthermore, their treatment differs from Shanghan. Shanghan enters the Foot meridians, while Warm pathogens involve the Hand meridians. Shanghan requires surface-releasing methods, whereas Warm pathogens contraindicate sweating. Shanghan medications should be acrid-warm, while Warm pathogen medications should be acrid-cool. Failure to distinguish these will inevitably lead to misdiagnosis and mistreatment. Therefore, this collection specifically incorporates Warm-Thermal theory and applies Warm-Thermal methods as adjunctive treatments. Syndromes listed under Taiyang represent typical Shanghan, while those listed under Yangming and Shaoyang channels typically involve Warm-Thermal elements. This is because Shaoyang is the source of Wood and Fire, and Yangming is the reservoir of Dampness and Heat; thus, Wind-Warm and Warm-Thermal pathogens naturally resonate with these energies. Other syndromes such as Huoluan and Xianggangjiao have their respective treatments detailed in their own sections.
Shao's Commentary: These sentences differentiate the origins of Shanghan and Warm-Thermal diseases and highlight the differences in treatment methods and medication. This deserves careful attention.
