张仲景说：太阳中热，就是暑病。患者汗出，恶寒，身体发热并且口渴。《金匮要略》说：用白虎加人参汤主治。郭雍说：也有恶风的，是因为出汗太多所致。
又说：太阳中暍（暑邪），身体发热且沉重疼痛，脉象微弱，这是因为夏季损伤了冷水，水气行于皮肤之间所导致的。《金匮要略》说：用瓜蒂散主治。
又说：太阳中暍，发热恶寒，身体沉重且疼痛，脉象弦细芤迟，小便不利，感觉像被冷水洒在身上一样寒战，手足逆冷，稍微活动一下身体就发热，张口呼吸，前额板齿干燥。如果发汗，则恶寒加重；如果用温针，则发热加重；如果多次攻下，则淋证加重。庞安常说：宜用大小橘皮汤。大橘皮汤治疗动气在下、不可发汗者；小橘皮汤主治手足逆冷、呕吐呃逆，即由生姜和橘皮两味药组成的方剂。
问：中暑、中暍、热病，如何区别？郭雍说：冬季感受寒邪，因暑气而随后发作的，称为热病；冬季没有感受寒邪，而在夏季直接感受暑邪的，称为中暑。中暑，就是中暍。都是太阳经受病，所以热病确实属于伤寒范畴，而中暑是与伤寒相似的病症。《活人书》说：夏季发热恶寒，头痛，身体肢节疼痛沉重，脉象洪盛的，是热病；夏季自汗恶寒，身体发热且口渴，脉象微弱的，是中暑。大致上中暑与热病的症状相似，但通过脉象盛实或虚弱来区分。《甲乙经》说：脉盛身寒，得之于伤寒；脉虚身热，得之于伤暑。大概是因为寒邪伤形而不伤气，所以脉盛；热邪伤气而不伤形，所以脉虚。伤寒导致肢节疼痛沉重，脉象洪盛，按之有力，这是冬季感寒深重，到夏季才发作。中暑则背部寒冷、面色垢浊，手足微冷，烦躁口渴口燥，只感到倦怠，四肢却不疼痛沉重，脉象微弱，按之无力，用白虎汤主治。出现厥逆恶寒的，用橘皮汤主治。头痛恶寒，心中烦躁，心下不适的，用五苓散最为适宜。
问：中暑为什么会感觉洒洒然寒战、恶寒？朱氏说：经文说：四时八风侵入人体，其中有寒暑之分。寒则皮肤紧缩，腠理闭塞；暑则皮肤松弛，腠理开泄。腠理开泄则感觉洒洒然寒冷，腠理闭塞则感觉热而闷。近代人不分辨中热和中暑，或用治疗热病的方法处理，又复用温热药物，必然导致发黄、斑疹发出，甚至造成蓄血，尤其应当戒除。
问：热病、暑病、中暍，三者名称不同，各家不加区分，怎么样？郭雍说：热病也可以称为暑，中暍也可以称为暑，所以有时说热，有时说暑。其起始应当有热和中暍这两种病，因为它们相通都可以称为暑，所以有三个名字，因此难以区分。《素问》说：热病，都属于伤寒一类。这是从“热”的角度来说的。
又说：夏至日之前发病的叫温病，夏至日之后发病的叫暑病。这是从“暑”的角度来说的。这两者其实是一样的。张仲景、王叔和说：中暍而立即发病的，名叫伤寒；不立即发病的，到春天变为温病，到夏天变为暑病。
又说：劳苦之人，春夏季节多患温热病，这一种病，有的称为暑，有的称为热。所以巢元方在伤寒之外，单独列出热病一门，首先说：暑病，是热重于温。所以热病也称为暑。庞安常又写出暑病一篇，将其归为伤寒中的热病。另外两家所载，都以《素问·五脏热病》为主，所以名同而实异。只有朱氏区分热病与中暑不相混淆。然而朱氏所说的热病，就是伤寒；所说的中暑，就是中暍。他的意思容易明白，不让人困惑，应当采用朱氏的名称。其他诸家的论述，也未尝不同，只是名称特异罢了。
Zhang Zhongjing said: Taiyang heat-stroke (Taiyang zhong re) is this condition. The patient sweats, fears cold, has a fever, and feels thirsty. *Jin Gui Yao Lue* states: It is primarily treated with Baihu Jia Renshen Tang (White Tiger Decoction plus Ginseng). Guo Yong stated: There are also cases of fearing wind, which is due to excessive sweating.
He further said: In Taiyang heat-stroke (Zhong Yue), the body feels hot and heavy with pain, and the pulse is faint and weak. This is caused by injuring cold water in summer, leading to water qi circulating within the skin. *Jin Gui Yao Lue* states: It is primarily treated with Goudi San (Melon Sepal Powder).
He further said: In Taiyang heat-stroke (Zhong Yue), there is fever and aversion to cold, heaviness of the body with pain, and the pulse is string-taut, fine, hollow, and slow. Urination is difficult or scanty; the person shivers as if sprinkled with cold water, and the hair stands on end. The hands and feet are cold. Upon slight exertion, the body becomes hot. The mouth opens to breathe, and the front teeth appear dry. If sweat-inducing methods are used, the aversion to cold will worsen. If warm needle therapy is applied, the fever will intensify. If purgatives are used repeatedly, strangury (Lin syndrome) will worsen. Pang Anchang stated: Da Xiao Ju Pi Tang (Large and Small Tangerine Peel Decoctions) should be used. Da Ju Pi Tang treats "moving Qi" located below, where sweating is contraindicated. Xiao Ju Pi Tang primarily treats cold hands and feet with vomiting and hiccups; it consists of only two herbs: Sheng Jiang (Fresh Ginger Rhizome) and Ju Pi (Tangerine Peel).
Question: How to differentiate between heat-stroke (Zhong Shu), heat-stroke from summer-heat (Zhong Yue), and febrile disease (Re Bing)? Guo Yong answered: Febrile disease occurs when one is injured by cold in winter, which manifests later due to summer-heat qi. Heat-stroke (Zhong Shu) occurs when one is not injured by cold in winter but is directly injured by summer-heat in summer. Heat-stroke (Zhong Shu) is essentially Zhong Yue. Both involve pathogenic invasion of the Taiyang channel. Therefore, febrile disease truly belongs to the category of Cold Damage (Shang Han), while heat-stroke resembles Cold Damage. *Huo Ren Shu* states: In summer, if there is fever, aversion to cold, headache, heavy pain in the body and joints, and a surging pulse, it is a febrile disease. In summer, if there is spontaneous sweating, aversion to cold, fever, thirst, and a faint pulse, it is heat-stroke. Generally, the external symptoms of heat-stroke and febrile disease are similar, but they are distinguished by whether the pulse is surging (excess) or faint (deficiency). *Jia Yi Jing* states: A surging pulse with cold body indicates injury by cold (Shang Han); a faint pulse with hot body indicates injury by summer-heat (Shang Shu). This is because cold injures the form/body but not the Qi, resulting in a surging pulse; heat injures the Qi but not the form, resulting in a faint pulse. Cold damage causes heavy pain in limbs and joints, with a surging pulse that is forceful upon pressure; this is deep cold contracted in winter manifesting in summer. Heat-stroke presents with coldness in the back, greasy facial complexion, slightly cold hands and feet, irritability, thirst, and dry mouth, with a feeling of fatigue, but without heavy pain in the limbs. The pulse is faint and weak upon pressure. It is treated with Baihu Tang (White Tiger Decoction). For cases with cold extremities and aversion to cold, Ju Pi Tang (Tangerine Peel Decoction) is used. For headache, aversion to cold, mental restlessness, and discomfort in the epigastrium, Wu Ling San (Five-Ingredient Powder with Poria) is most effective.
Question: Why does heat-stroke cause shivering (Sa Sa Ran Mao Song) and aversion to cold? Zhu Shi stated: The classics say: When the eight winds of the four seasons invade humans, there is differentiation between cold and heat. Cold causes skin tightening and closure of interstices (Cou Li); heat causes skin relaxation and opening of interstices. When open, one feels chilly (Sa Ran Han); when closed, one feels hot and stifled. Modern practitioners often fail to distinguish between heat-injury and summer-heat-injury, treating them as febrile diseases and using warm-hot medicines. This inevitably leads to jaundice and macular eruptions, or even blood stasis accumulation. This must be strictly avoided.
Question: Febrile disease, summer-heat disease, and Zhong Yue have different names, yet various schools do not distinguish them. What is your view? Guo Yong answered: Febrile disease can also be called summer-heat; Zhong Yue can also be called summer-heat. Thus, sometimes "heat" is mentioned, and sometimes "summer-heat." Initially, there are two conditions involving heat: febrile disease and Zhong Yue. Because they are interconnected, they can all be termed summer-heat, hence the three names, making them difficult to distinguish. *Su Wen* states: Febrile diseases are all of the category of Cold Damage. This refers to the aspect of "heat."
It further states: Diseases occurring before the Summer Solstice are called Warm Disease (Wen Bing); those occurring after the Summer Solstice are called Summer-Heat Disease (Shu Bing). This refers to the aspect of "summer-heat." Essentially, these two are the same. Zhang Zhongjing and Wang Shuhe stated: If Zhong Yue manifests immediately, it is named Cold Damage (Shang Han). If it does not manifest immediately, it transforms into Warm Disease in spring and Summer-Heat Disease in summer.
It further states: Laborers are prone to warm-heat diseases in spring and summer. This single condition is referred to as either summer-heat or heat. Therefore, Chao Yuanfang, outside of Cold Damage, established a separate section for Febrile Disease, stating first: Summer-heat disease is heat heavier than warmth. Thus, febrile disease is also called summer-heat. Pang Anchang further wrote a chapter on Summer-Heat Disease, classifying it as the febrile disease within Cold Damage. Furthermore, both authors based their descriptions on *Su Wen: Re Bing of the Five Zang Organs*. Thus, the names are the same, but the realities differ. Only Zhu Shi clearly differentiated between febrile disease and heat-stroke without confusion. However, Zhu Shi's "febrile disease" refers to Cold Damage, and his "heat-stroke" refers to Zhong Yue. His meaning is clear and avoids confusion. We should adopt Zhu Shi's nomenclature. The discussions of other schools are not fundamentally different; only the names vary.
