伤寒为外感百病之总名。故张仲景医圣着伤寒论。后贤推为通治六气感证之要书。
兹言兼证者。或寒邪兼他邪。或他邪兼寒邪。二邪兼发者也。其证约二十有一。条治于

(俗称冷伤风。仲景伤寒论名曰中风)
【因】同一感受风寒。寒甚于风者为正伤寒。风重于寒者为冷伤风。冷伤风者。由
其人猝伤冷风。或先感于寒。续伤于风。较四时感冒为重。故俗称重伤风。
【证】头痛身热。恶风怕冷。鼻寒声重。咳嗽清涕。痰多白滑而稀。或自汗而咳甚
。或无汗而喘息。舌苔白薄而滑。甚或白滑而腻。
【脉】伤寒左手脉当浮紧。今反浮缓。右手浮滑者。此伤寒见风脉。内经所谓伤于
风者上先受之。风寒客于人。病入舍于肺。乃营卫并伤之候。难经推为五种伤寒之一。
与正伤寒同而不同者。正伤寒多先伤足太阳经。冷伤风多先伤手太阴经也。
【治】自汗而咳者。先调营卫以治咳。桂枝橘皮汤加杏仁(去皮勿研三钱)、前胡
(二钱)、无汗而喘
者。先疏肺气以定喘。新加三拗汤加减。此后痰稀咳甚者。小青龙汤去麻黄。加杏仁、

病自除根。失治误治。往往延久不愈。酿成肺病。轻变痰饮痰火。重变肺胀肺痨。目
见甚多。务望医家病家两慎之。
【秀按】冷伤风一证。内经首先发明。谓风从外入。令人振寒。汗出头痛。身重恶
寒。治在风府。其次张氏伤寒论。一则谓太阳病。发热汗出。恶风脉缓者。名为中风。
一则谓太阳中风。脉阳浮而阴弱。阳浮者热自发。阴弱者汗自出。啬啬恶寒。淅淅恶风
。翕翕发热。鼻鸣干呕者。桂枝汤主之。此皆后世所称之风寒病也。后贤谓有冒伤中之
不同。冒风为轻。伤寒为重。中风为最重。故又泥于越人长沙之谓风为中。与虚风猝倒
为中风。二病之名目相混。岂知古人伤与中字义无殊。如云风伤卫寒伤营是矣。若以恶
风自汗与恶寒无汗两证。辨伤风与伤寒之异。尚未可根据为的据。唯一则但有头痛鼻涕。
而周身不痛。一则头身俱痛。腰与骨节亦疼。一则脉浮缓。一则脉浮紧。证与脉显然各
别。至于汗之有无。正伤寒证固无汗。重伤风证亦有无汗者。故桂枝汤本是风寒发汗之
剂。不过较麻黄汤为和缓耳。或谓其无汗能发。有汗能止者。骑墙语最足误人。
【廉勘】重伤风一证。证虽极繁。而病患多不注意。病至难治。而医家漫不经心。
皆泥于伤风为小恙故耳。岂知咳嗽一日不除。病根一日不芟。故谚云伤风咳嗽。郎中对

【荣斋按】重伤风如三、四日后,恶风怕冷的情形已除,剩有发热、头痛或全身疼
痛,鼻寒声重,咳嗽痰多者;聂云台先生有重伤风标准汤,可供采用。方为∶黄芩二钱
、白芍二钱、连翘三钱、象贝三钱、蝉蜕一钱、竹茹三钱、桑白皮三钱、桑叶钱半、枳
壳一钱、杏仁三钱、枇杷叶三钱包煎、薄荷八分泡勿煎。重庆市第七民众医院沈仲圭先
生认为∶“此方总的功效,是发汗解热,镇咳祛痰,用于流行性感冒(即重伤风),确
是一个好药方;其中白芍一味,根据近代中医用药法则,似觉突出,不如删去为妥。”
沈先生并把重伤风的病原和症状发展,也作了有系统的叙述∶“重伤风即流行性感冒,
其病源为滤过性病毒,潜伏期一至三日。此病起病急剧,畏寒发热,周身疼痛,背部头
部四肢痛得更厉害,体温上升很快(38℃─ 4l℃)上呼吸道炎症,也很快发生,如鼻流
清涕,干咳,喉痛,胸骨疼痛,结膜充血,全身衰弱。血象∶白血球减少。血液培养,
无细菌发现。预后良好,病程约五日热退。“以上所谈,是单纯型流感,另有一种称为
“有并发症的单纯型流感”,即继发化脓性支气管炎的流感;那就是俞根初先生所提出
的∶“延久不愈,轻变痰饮,重变肺胀。”的症候了。
伤寒是外感各类疾病的总称。因此,医圣张仲景撰写了《伤寒论》。后世贤者将其推崇为治疗六气(风、寒、暑、湿、燥、火)所致病证的重要著作。
这里所说的兼证,是指寒邪兼夹其他邪气,或者其他邪气兼夹寒邪,两种邪气同时发病的情况。其证候大约有二十一种,分别论述如下。
【病因】同样是感受风寒,寒邪重于风邪的称为正伤寒;风邪重于寒邪的称为冷伤风。冷伤风是由于人突然受到冷风侵袭,或者先感受寒邪,随后又受风邪侵袭所致,比四季常见的感冒更为严重,所以俗称重伤风。
【症状】头痛,身体发热,怕风畏寒,鼻塞声音重浊,咳嗽,流清鼻涕,痰多且白滑稀薄。或者自汗且咳嗽加重,或者无汗且喘息。舌苔白薄而滑,甚至白滑而腻。
【脉象】伤寒病的左手脉应当浮紧,现在反而浮缓;右手脉浮滑,这是伤寒见到风邪的脉象。《内经》所谓“伤于风者,上先受之”,风寒侵犯人体,病邪入舍于肺,这是营卫两伤的征候。《难经》将其列为五种伤寒之一。与正伤寒相同而又不同的地方在于:正伤寒多先损伤足太阳经,而冷伤风多先损伤手太阴经。
【治法】对于自汗且咳嗽的患者,先调和营卫以治疗咳嗽,用桂枝橘皮汤加杏仁(去皮不研磨,三钱)、前胡(二钱);对于无汗且喘息的患者,先疏理肺气以平喘,用新加三拗汤加减。此后若痰稀薄且咳嗽严重者,用小青龙汤去掉麻黄,加杏仁、橘红,以消痰止咳。若痰多且咳嗽严重者,用越婢加半夏汤,宣通肺气以定喘。嘱咐病人务必禁忌酸冷、油腻等食物,病根自然能除。如果失治或误治,往往拖延日久不愈,酿成肺病,轻则变为痰饮、痰火,重则变为肺胀、肺痨,这种情况目见甚多,务必希望医生和病家都谨慎对待。
【秀按】冷伤风这一证候,《内经》首先阐明,说风从外侵入,使人战栗发冷,出汗头痛,身体沉重恶寒,治疗取穴风府。其次张仲景的《伤寒论》,一则说太阳病,发热汗出,恶风脉缓的,名为中风;二则说太阳中风,脉象阳浮而阴弱,阳浮者热自发,阴弱者汗自出,啬啬恶寒,淅淅恶风,翕翕发热,鼻鸣干呕的,用桂枝汤主治。这些都是后世所称的风寒病。后世贤者认为有冒风、伤风、中风的不同,冒风较轻,伤寒较重,中风最重。因此又拘泥于扁鹊(越人)和张仲景(长沙太守)的说法,将“风为中”与虚风猝倒导致的“中风”这两个病名混淆。哪里知道古人说的“伤”与“中”字义没有区别,如说“风伤卫,寒伤营”就是这样。如果用恶风自汗与恶寒无汗这两个证候来辨别伤风与伤寒的差异,还不足以作为确切的依据。唯一确定的是:一则只有头痛流鼻涕,而周身不痛;一则头身俱痛,腰部和骨节也疼;一则脉浮缓,一则脉浮紧,证候与脉象显然各不相同。至于汗的有无,正伤寒证确实无汗,但重伤风证也有无汗的情况。所以桂枝汤本是用于风寒发汗的方剂,只不过比麻黄汤和缓罢了。有人说它无汗能发汗,有汗能止汗,这种骑墙的话最足以误导人。
【廉勘】重伤风这一证候,虽然症状极多繁杂,但患者往往不注意,病情发展到难以治疗时,医生也漫不经心,都是因为拘泥于伤风是小病的原因。哪里知道咳嗽一天不消除,病根就一天不能铲除,所以谚语说“伤风咳嗽,郎中对头”,又说“伤风不醒便成痨”。前代哲人如徐灵胎,还著有《伤风难治论》,说伤风由皮毛进入肺脏,肺为娇脏,太寒则风气凝结而不能排出,太热则火灼肺而动血,太润则生痰饮,太燥则耗津液,太泄则汗出而阳虚,太涩则气闭而邪结。并且有人将其视为小病,不避风寒,不慎饮食,经年累月,病机日益加深,有的成为血证,有的成为肺痿,有的成为哮喘,有的成为怯弱,比比皆是。看这些情况,伤风因失治误治而导致严重后果,古今是一样的,难怪久咳不愈变成肺痨的人层出不穷。我治疗这个证候,常常用危言耸听的话警告病人,叮嘱他们忌口避风,自制疏风止嗽汤。(荆芥穗一钱半、苏薄荷一钱、光杏仁二钱、广皮红八分、百部一钱半、清炙甘草六分、紫菀二钱、白前一钱半。)多次投药都有疗效。既不太热太燥太泄,也不太寒太润太涩,所以病人放心肯服用。方子虽然平淡,收效却很多。只是对于那些好赌博、贪酒色、固执己见的人,很难取得完全的效果。医生应当忠告并善于引导他们。
【荣斋按】重伤风如果在三、四天后,恶风怕冷的情况已经消除,剩下发热、头痛或全身疼痛,鼻塞声重,咳嗽痰多的情况;聂云台先生有一个重伤风标准汤,可供采用。方剂组成是:黄芩二钱、白芍二钱、连翘三钱、象贝母三钱、蝉蜕一钱、竹茹三钱、桑白皮三钱、桑叶一钱半、枳壳一钱、杏仁三钱、枇杷叶三钱(包煎)、薄荷八分(泡服勿煎)。重庆市第七民众医院的沈仲圭先生认为:“此方总的功效,是发汗解热,镇咳祛痰,用于流行性感冒(即重伤风),确实是一个好药方;其中白芍一味,根据近代中医用药法则,似乎显得突出,不如删去为妥。”沈先生还把重伤风的病原和症状发展,作了系统的叙述:“重伤风即流行性感冒,其病源为滤过性病毒,潜伏期一至三日。此病起病急剧,畏寒发热,周身疼痛,背部头部四肢痛得更厉害,体温上升很快(38℃─41℃),上呼吸道炎症也很快发生,如鼻流清涕,干咳,喉痛,胸骨疼痛,结膜充血,全身衰弱。血象:白血球减少。血液培养,无细菌发现。预后良好,病程约五日热退。”以上所谈,是单纯型流感,另有一种称为“有并发症的单纯型流感”,即继发化脓性支气管炎的流感;那就是俞根初先生所提出的:“延久不愈,轻变痰饮,重变肺胀。”的症候了。
Shanghan (Cold Damage) is the general term for all external contraction diseases. Therefore, Zhang Zhongjing, the Medical Sage, authored the *Treatise on Cold Damage* (*Shanghan Lun*). Later scholars have highly regarded it as an essential book for treating conditions caused by the six climatic factors (Wind, Cold, Summer-heat, Dampness, Dryness, Fire).
The "combined syndromes" discussed here refer to situations where Cold pathogen combines with other pathogens, or other pathogens combine with Cold pathogen, resulting in the simultaneous onset of two pathogens. There are approximately twenty-one such syndromes, which are detailed below.
(Commonly known as Cold Wind-Cold; in Zhang Zhongjing's *Treatise on Cold Damage*, it is called Wind Strike.)
[Etiology] When contracting both Wind and Cold, if Cold is heavier than Wind, it is called Zheng Shanghan (Standard Cold Damage); if Wind is heavier than Cold, it is called Leng Shangfeng (Cold Wind-Cold). Leng Shangfeng occurs when a person suddenly suffers from cold wind, or first contracts Cold and subsequently suffers from Wind. It is more severe than common colds occurring in the four seasons, hence commonly known as Heavy Wind-Cold.
[Symptoms] Headache, feverish body sensation, aversion to wind and cold, nasal congestion with heavy voice, coughing with clear nasal discharge, profuse white, slippery, and thin sputum. Alternatively, spontaneous sweating with aggravated cough, or no sweating with wheezing. The tongue coating is white, thin, and slippery, or even white, slippery, and greasy.
[Pulse] In Shanghan, the left-hand pulse should be Floating-Tight (Fu Jin), but now it is instead Floating-Slow (Fu Huan); the right-hand pulse is Floating-Slippery (Fu Hua). This indicates a Wind-pulse appearing in Shanghan. As stated in the *Neijing* (Classic of Internal Medicine): "Those injured by Wind suffer first in the upper part." When Wind and Cold invade humans, the disease enters and resides in the Lung. This is a sign of injury to both Ying (Nutritive) and Wei (Defensive) Qi. The *Nanjing* (Classic of Difficult Issues) classifies it as one of the five types of Shanghan. The similarity and difference between this and Standard Shanghan lie in the meridian involvement: Standard Shanghan usually injures the Foot-Taiyang Meridian first, whereas Leng Shangfeng usually injures the Hand-Taiyin Meridian first.
[Treatment] For patients with spontaneous sweating and cough, first harmonize Ying and Wei to treat the cough, using Guizhi Jupi Tang (Cinnamon Twig and Tangerine Peel Decoction) plus Xingren (Almond Kernel, 3 qian, peeled and not ground) and Qianhu (Peucedani Radix, 2 qian). For patients with no sweating and wheezing, first diffuse Lung Qi to calm wheezing, using Xinjia San'ao Tang (New Modified Three-Ao Decoction) with modifications. Subsequently, for those with thin sputum and severe cough, use Xiao Qinglong Tang (Minor Blue Dragon Decoction) removing Mahuang (Ephedrae Herba), adding Xingren (Almond Kernel) and Juhong (Citri Reticulatae Pericarpium Rubrum) to resolve phlegm and stop cough. For those with profuse sputum and severe cough, use Yeshi Banxia Tang (Yin-Breast Decoction with Pinellia) to diffuse Lung Qi and calm wheezing. Patients must be instructed to strictly avoid sour, cold, and greasy foods so that the root of the disease may be eliminated. Failure to treat or mis-treatment often leads to chronic non-healing conditions, developing into Lung diseases: mild cases transform into Phlegm-Fluid or Phlegm-Fire, while severe cases transform into Feizhang (Lung Distension) or Feilao (Lung Consumption). These occurrences are frequent; doctors and patients alike must exercise caution.
[Xiu's Commentary] The syndrome of Leng Shangfeng was first elucidated in the *Neijing*, stating that Wind entering from outside causes chills, sweating, headache, heaviness of the body, and aversion to cold, treated at Fengfu (GV16). Secondly, in Zhang's *Treatise on Cold Damage*, it states: "Taiyang disease, with fever, sweating, aversion to wind, and slow pulse, is named Wind Strike"; and "Taiyang Wind Strike, with Yang-floating and Yin-weak pulse, Yang-floating indicates spontaneous heat, Yin-weak indicates spontaneous sweating, accompanied by chilly aversion to cold, shivering aversion to wind, warm-feeling fever, nasal roaring, and dry vomiting, is primarily treated with Guizhi Tang (Cinnamon Twig Decoction)." These are all what later generations call Wind-Cold diseases. Later scholars distinguished between Mao Feng (Encountering Wind), Shang Feng (Injured by Wind), and Zhong Feng (Struck by Wind), considering Mao Feng mild, Shanghan heavy, and Zhong Feng heaviest. Consequently, they confused the concept of "Wind as Middle" from Bian Que (Yue Ren) and Zhang Zhongjing with "Zhong Feng" caused by empty wind causing sudden collapse. Did they not know that in ancient texts, "Shang" (Injure) and "Zhong" (Strike/Middle) had similar meanings, as in "Wind injures Wei, Cold injures Ying"? Using only aversion-to-wind-with-sweating versus aversion-to-cold-with-no-sweating to distinguish Shangfeng from Shanghan is insufficient as definitive evidence. The clear distinction lies in: one has only headache and runny nose without body pain; the other has head and body pain, including waist and joints; one has Floating-Slow pulse, the other Floating-Tight pulse. Regarding sweating: Standard Shanghan indeed has no sweat, but Heavy Wind-Cold can also present with no sweat. Thus, Guizhi Tang is originally a formula for inducing sweating in Wind-Cold, merely milder than Mahuang Tang (Ephedra Decoction). Some claim it induces sweating when there is none and stops sweating when there is some; this equivocal statement is most misleading.
[Lian's Examination] Although the symptoms of Heavy Wind-Cold are numerous and complex, patients often pay little attention to them, and doctors become careless until the condition becomes difficult to treat, simply because they consider Wind-Cold a minor ailment. They do not realize that as long as cough persists, the root of the disease remains. Hence the proverb says, "For Wind-Cold cough, even an ordinary doctor suffices," and "Wind-Cold unawakened becomes Consumption." Ancient philosophers like Xu Lingtai wrote "On the Difficulty of Treating Wind-Cold," stating that Wind-Cold enters from skin and hair into the Lung. The Lung is a delicate organ: too cold condenses Wind Qi preventing expulsion; too hot burns Lung Yin causing bleeding; too damp generates Phlegm-Fluid; too dry consumes Body Fluids; too draining causes sweating leading to Yang deficiency; too astringent causes Qi closure and pathogen entrapment. Furthermore, people who view it as a trivial illness, fail to avoid Wind-Cold, and neglect diet, allow the pathology to deepen over years, resulting in Blood Syndromes, Feiwei (Lung Flaccidity), Asthma, or Debility, which are common. Observing this, mistreatment of Wind-Cold leading to severe consequences is consistent across ancient and modern times, explaining why chronic cough turning into Consumption appears frequently. I treat this syndrome by warning patients seriously, instructing them to observe dietary restrictions and avoid wind, prescribing my self-made Shufeng Zhisou Tang (Dispersing Wind and Stopping Cough Decoction): Jingjie Sui (Schizonepetae Spica, 1.5 qian), Su Bohe (Menthae Haplocalycis Herba, 1 qian), Guang Xingren (Prunus Armeniacae Semen, 2 qian), Guang Pi Hong (Citri Reticulatae Pericarpium Rubrum, 0.8 qian), Baibu (Stemonae Radix, 1.5 qian), Qing Zhi Gancao (Glycyrrhizae Radix et Rhizoma Praeparatum cum Melle, 0.6 qian), Ziwan (Asteris Radix, 2 qian), Baiqian (Cynanchi Stauntonii Radix, 1.5 qian). Repeated administration yields effective results. It is neither too hot, dry, nor draining, nor too cold, damp, nor astringent, so patients accept it willingly. Though the formula is plain, its efficacy is significant. However, for those addicted to gambling, excessive alcohol/sex, or stubborn in their ways, complete cure is difficult. Doctors must advise faithfully and guide them well.
[Rongzhai's Commentary] If, after three or four days of Heavy Wind-Cold, the aversion to wind and cold subsides, leaving fever, headache or generalized body pain, nasal congestion with heavy voice, cough, and profuse sputum, Mr. Nie Yuntai offers a Standard Formula for Heavy Wind-Cold. The prescription is: Huangqin (Scutellariae Radix, 2 qian), Baishao (Paeoniae Radix Alba, 2 qian), Lianqiao (Forsythiae Fructus, 3 qian), Xiang Bei (Fritillariae Thunbergii Bulbus, 3 qian), Chantui (Cicadae Periostracum, 1 qian), Zhuru (Bambusae Caulis in Taenia, 3 qian), Sangbaipi (Mori Cortex, 3 qian), Sangye (Mori Folium, 1.5 qian), Zhike (Aurantii Fructus Immaturus, 1 qian), Xingren (Prunus Armeniacae Semen, 3 qian), Pipaye (Loquati Folium, 3 qian, decocted in bag), Bohe (Menthae Haplocalycis Herba, 0.8 qian, infused, not decocted). Mr. Shen Zhonggui of Chongqing Seventh People's Hospital believes: "The overall effect of this formula is inducing sweating, resolving heat, suppressing cough, and expelling phlegm. It is indeed an excellent formula for Influenza (i.e., Heavy Wind-Cold); however, according to modern TCM medication principles, the inclusion of Baishao seems prominent, and it might be better to omit it." Mr. Shen also systematically described the etiology and symptom progression of Heavy Wind-Cold: "Heavy Wind-Cold is Influenza. Its pathogen is a filterable virus with an incubation period of one to three days. The onset is acute, with chills, fever, and generalized body pain, particularly severe in the back, head, and limbs. Body temperature rises rapidly (38°C–41°C). Upper respiratory tract inflammation develops quickly, manifesting as clear nasal discharge, dry cough, sore throat, sternal pain, conjunctival congestion, and general weakness. Hemogram shows leukopenia. Blood culture reveals no bacteria. Prognosis is good, with fever subsiding after about five days." The above refers to simple influenza. Another type is "simple influenza with complications," i.e., influenza secondary to suppurative bronchitis; this corresponds to the syndrome proposed by Mr. Yu Genchu: "If prolonged and unhealed, mild cases transform into Phlegm-Fluid, severe cases transform into Lung Distension."
