江诚曰∶介宾先生谓阴暑多于阳暑，最为确切。今人治暑不别阴阳，一见发烧，遂投凉药，若此贸贸，则害人匪浅
矣。
王安道曰∶暑热之气一也，皆夏月中伤其邪而为病，岂以一暑热分为阴阳二证而名之邪？其避暑于深堂大厦，及恣

以暑月伤寒，暑月伤热别之。
雷少逸说：长夏季节感受暑邪，有阴暑和阳暑的区别。所谓阴暑病，是因为天气炎热蒸腾，人们在深堂大厦中纳凉，或者使用大扇、风车吹风而得病的，这是静处时所得的阴证。其脉象浮弦有力，或浮紧，头痛恶寒，身体拘急不舒，肢节疼痛且心烦，肌肤高热但无汗，这是因为阴寒逼迫，导致周身阳气不能舒展升发，适宜用辛温解表法治疗，减去防风，增加香薷、藿香来治疗。伴有呕吐逆气的加茯苓、半夏；伴有腹泻的加厚朴、木香。又有阳暑病，是由于长途旅行，或在农田野外劳作，在烈日下受逼而得病的，这是活动时所得的阳证。其脉象浮洪有力，或洪数，面色垢浊，气喘咳嗽，壮热心烦，口渴想喝水，热气蒸腾且自汗出，这是因为炎热熏蒸，导致周身内外皆热，适宜用清凉涤暑法，去掉扁豆、通草，加入石膏、西洋参来治疗。伴有呕吐逆气的加竹茹、黄连；伴有腹泻的加葛根、荷叶。更应当审察患者的体质虚实来用药，自然没有不妥当的地方。
张介宾说：阴暑证，有的在表，有的在里，只有富贵安逸的人多有此病。总归是由于放纵情欲任性，不慎风寒所致。阳暑证，只有辛苦劳役的人多有此病，是由于触犯冒犯暑热，是形势所迫不得不如此。然而暑热逼人，人们畏惧可以躲避，能躲避则犯病的人就少；阴寒袭人，感觉舒适而不知防备，不知防备则犯病的人就多。所以凡是患暑病的人，阳暑多不见到，而阴暑占八九成。现在的人治疗暑病，只要见到发热头痛等症状，就一定说是中暑，而所用的无非是寒凉药物，这种不达医理的情况也太严重了。
江诚说：张介宾先生认为阴暑多于阳暑，最为确切。现在的人治疗暑病不辨别阴阳，一见发烧，就投用凉药，如果这样糊里糊涂地治病，那么害人不浅啊。
王安道说：暑热之气是一样的，都是夏月受到邪气而生病，怎么能把一个暑热分为阴、阳两证来命名呢？那些避暑于深堂大厦，以及恣意食用藏冰瓜果等寒凉之物的人，正是《内经》所说的“口得寒物，身犯寒气”的病，自然应当同秋冬季节即发的阴证伤寒一样处理，不可以命名为中暑。
沈尧封说：暑、热、火，都是夏令一气（夏季气候）的名称。后人不明察，胡乱传播说法，其实与病情无关，反而混淆了医理。
杨如侯说：头痛恶寒，身体拘急，肢体疼痛，心烦，肌肤高热无汗，这是暑月被寒邪所伤。头痛伴有燥热感，肌肤高热，极度口渴引水饮用，大汗淋漓，气短无力不想动，这是暑月被热邪所伤。《内经》说：“炎火太过，炎暑流行”，这说明暑就是火，就是热。后人把静处时得的称为中暑，活动时得的称为中热，将暑、热分为阴、阳两证，命名与古义不合。更有设立阴暑、阳暑名称的，也属于徒然扰乱人心。这里是以暑月伤寒、暑月伤热来加以区别的。
Lei Shaoyi stated: In the late summer season, contracting summerheat pathogen presents with distinctions between Yin Summerheat and Yang Summerheat. The disease of Yin Summerheat arises from staying in deep halls and large mansions to seek coolness when the weather is hot and steaming, or from exposure to large fans and windmills; this is a Yin syndrome obtained through stillness. The pulse is floating, wiry, and forceful, or floating and tight; symptoms include headache, aversion to cold, bodily stiffness and constraint, pain in the limbs and joints accompanied by vexation, high fever of the skin without sweat. This is caused by Yin-cold forcing the body's Yang Qi to be unable to extend and ascend. It is appropriate to use the Acrid-Warm Exterior-Resolving method, removing Fangfeng (Saposhnikovia Root) and adding Xiangru (Elsholtzia Herb) and Huoxiang (Patchouli Herb). For vomiting and regurgitation, add Fuling (Poria) and Banxia (Pinellia Tuber); for diarrhea, add Houpo (Magnolia Bark) and Muxiang (Aucklandia Root).
There is also the disease of Yang Summerheat, which occurs due to long-distance travel or labor in fields under the pressing sun; this is a Yang syndrome obtained through movement. The pulse is floating, surging, and forceful, or surging and rapid; symptoms include a dirty complexion, panting and coughing, high fever with vexation, thirst with desire to drink, steaming heat with spontaneous sweating. This is caused by intense heat steaming the body, making the interior and exterior all hot. It is appropriate to use the Cooling-Clearing and Summerheat-Scouring method, removing Bian Dou (Dolichos Lablab Seed) and Tong Cao (Tetrapanax Pith), and adding Shigao (Gypsum Fibrosum) and Yangshen (American Ginseng). For vomiting and regurgitation, add Zhuru (Bamboo Shavings) and Huanglian (Coptis Rhizome); for diarrhea, add Gegen (Kudzu Root) and Heye (Lotus Leaf). One must further examine the patient's constitution and deficiency/excess status to prescribe medication, ensuring no impropriety.
Zhang Jiebin stated: Yin Summerheat syndrome may be at the exterior or in the interior, and is mostly seen in wealthy and idle people. It is generally caused by indulgence and lack of caution regarding wind and cold. Yang Summerheat syndrome is mostly seen in those who work hard and toil, caused by exposure to summerheat, which is often unavoidable due to circumstances. However, when summerheat presses upon people, they fear it and can avoid it, so few contract it; when Yin-cold attacks people, it feels pleasant and goes unnoticed, so many contract it. Therefore, among those suffering from summerheat diseases, Yang Summerheat is rarely seen, while Yin Summerheat accounts for eight or nine out of ten. Nowadays, when treating summerheat diseases, if one sees symptoms like fever and headache, one invariably says this is "Zhong Shu" (Summerstroke), using nothing but cooling herbs. This failure to understand medical principles is severe.
Jiang Cheng stated: Mr. Zhang Jiebin’s assertion that Yin Summerheat is more common than Yang Summerheat is most accurate. Nowadays, people treat summerheat without distinguishing Yin and Yang; upon seeing fever, they immediately administer cooling medicines. Such reckless practice harms people significantly.
Wang Andao stated: The Qi of summerheat and heat is the same; both are illnesses contracted in summer months due to pathogenic factors. How can one single summerheat pathogen be divided into Yin and Yang syndromes for naming? Those who avoid heat by staying in deep halls or by recklessly consuming ice-cooled fruits and melons are suffering from what the Classics call "mouth receiving cold substances, body encountering cold Qi." These should be treated similarly to Yin-type Cold Damage occurring in autumn and winter, and should not be named Summerstroke.
Shen Yaofeng stated: Summerheat, heat, and fire are all names for the single Qi of the summer season. Later generations failed to observe clearly, spreading baseless talk, which has no relevance to clinical conditions and instead confuses medical principles.
Yang Ruhou stated: Headache, aversion to cold, bodily stiffness, limb pain, vexation, and high fever of the skin without sweat indicate injury by cold during the summer month. Headache with dry heat sensation, high fever of the skin, extreme thirst with copious drinking, profuse sweating, and lethargy with inability to move indicate injury by heat during the summer month. The Classics state: "When flame-fire is excessive, summerheat prevails," indicating that summerheat is fire and heat. Later generations called the condition obtained through stillness "Zhong Shu" (Summerstroke) and that obtained through movement "Zhong Re" (Heatstroke), dividing summerheat and heat into Yin and Yang syndromes; this naming contradicts ancient meanings. Even more so, establishing the names Yin Summerheat and Yang Summerheat merely causes confusion. Here, the distinction is made between Cold Damage in summer and Heat Injury in summer.
