夏季突然倒地僵直，昏迷不省人事，称为暑厥（因暑邪导致的气机逆乱、昏厥）。应当区分阴证和阳证两种情况。
阳证表现为脉象洪大、快速但无力，身体发热、出汗，称为阳厥。这是因为暑邪和饮食损伤了脾胃。吃得越多，产生的热邪也越多。适宜使用连芍调中汤或辰砂六一散。先治疗其热邪，等到患者神志清醒后，再根据积食的多寡进行调理。古人说：“中暑不能用冷药，用了冷药就会死。”这是针对真正中暑的人说的，不是针对中热的人说的。现在的人一遇到热症，就动不动引用这句话，总归是因为没有弄明白中暑和中热的道理。
至于脉象沉细无力，肌肤不发烫，曾经吃过生冷瓜果的，称为寒厥。夏季人体元气发散在体表，腹部内部空虚，又因为吃了生冷食物损伤脾胃，寒气像冰一样伏住，导致食气闭塞不通。适宜使用浓朴温中汤。不可以急于进补。如果遇到汗多、身体冰冷的情况，才可以用香砂理中汤来治疗。许多医书谈到这个病，不分阴阳两种证候，混淆地说风邪和暑邪误用升散药物，害人不浅啊。
还有老人和体质虚弱的人，夏季患中痰证，症状大多类似暑厥。但是中痰的人，身体温暖而不冰冷，也没有高热，口角流涎，以此作为区别。（按语：将厥证分为寒热两类，是前人未曾阐发的见解，学习者尤其应当细心研究，以免草率误人性命。关键在于审察病症精详，然后用药，自然不会有其他歧途的困惑。）
中喝（暑热伤津耗气之证）的表现是：口渴喜欢饮水。患者感觉阵阵恶寒，微微发热，完全像伤寒。但是伤寒的脉象洪大，中喝的脉象细数。从这里可以辨别。中喝也有脉象洪大的情况，但其症状初起即口渴，与伤寒久病后才出现口渴的情况不同。体型肥胖的人，可以使用六一散清解暑热，使热邪从小便排出，不至于损伤津液。如果身体黑瘦的人，精血已被时令暑热所消耗，又以利小便为禁忌。适宜使用柴胡芍药汤，生津止渴，效果奇妙无穷。（按语：中喝与伤寒脉象都呈洪大的情况，伤寒脉细数是中喝，这是极其细微的区别，不容丝毫差错，关键在于细心讨论而自行领悟。）
In summer, sudden collapse with stiffness and unconsciousness is termed Shu Jue (Heat Stroke Collapse). It should be differentiated into Yin and Yang syndromes.
Yang syndrome presents with a flooding, rapid yet forceless pulse, body heat, and sweating, known as Yang Jue. This is caused by Summerheat and food damaging the Spleen and Stomach. The more food ingested, the greater the heat generated. One should use Lian Shao Tiao Zhong Tang (Coptis and Peony Decoction to Regulate the Middle) or Chen Sha Liu Yi San (Vermilion Cinnabar Six-to-One Powder) first to treat the heat. Wait until the patient regains clarity of mind, then adjust treatment based on the amount of food retention. Ancient texts state: "Summerstroke cannot be treated with cold [medicines]; using cold leads to death." This statement applies to those suffering from true Summerstroke, not those suffering from Heat Strike. Nowadays, people encountering any heat syndrome immediately cite this saying, primarily due to a lack of understanding of the principles distinguishing Summerstroke from Heat Strike.
Regarding cases where the pulse is deep, fine, and forceless, the skin is not hot, and there is a history of consuming raw, cold fruits and vegetables, this is termed Cold Jue. In summer, the body's Yuan Qi (Original Qi) disperses outward, leaving the abdomen empty. If one consumes raw and cold foods that damage the Spleen, the cold acts like ice, trapping the food qi and causing blockage. One should use Nong Po Wen Zhong Tang (Aucklandia and Magnolia Bark Decoction to Warm the Middle). Do not administer tonics hastily. Only if there is excessive sweating and a cold body should Xiang Sha Li Zhong Tang (Amomum and Aucklandia Decoction to Regulate the Middle) be used. Many medical books discuss this condition without distinguishing between Yin and Yang presentations, confusingly attributing harm to the misuse of ascending and dispersing agents for Wind and Summerheat, which causes significant harm.
Additionally, elderly or deficient individuals in summer may suffer from Phlegm Strike (Zhong Tan), which often resembles Shu Jue. However, patients with Phlegm Strike have warm bodies rather than cold ones, do not exhibit high fever, and have drooling at the corners of the mouth; these features serve as differentiators. (Note: Differentiating Jue into Cold and Heat types is an insight not previously expounded by predecessors. Students must study this carefully to avoid hasty errors that endanger lives. The key lies in precise symptom differentiation before prescribing, thereby avoiding therapeutic confusion.)
Zhong Re (Heat Strike) is characterized by thirst and a desire to drink. The patient experiences chilliness and mild fever, closely resembling Taiyang Cold Damage (Shang Han). However, while Cold Damage presents with a flooding pulse, Zhong Re presents with a fine and rapid pulse, allowing for differentiation. Zhong Re can also present with a flooding pulse; however, the key distinction is that thirst appears immediately at onset, unlike Cold Damage where thirst occurs only after prolonged illness. For obese individuals, Liu Yi San (Six-to-One Powder) can be used to clear heat, allowing it to exit via urination, thus preventing damage to Jin Ye (Body Fluids). For thin, dark-skinned individuals, whose Jing Blood (Essence and Blood) has been depleted by seasonal heat, promoting diuresis is contraindicated. Instead, Chai Hu Shao Yao Tang (Bupleurum and Peony Decoction) should be used to generate fluids and relieve thirst, yielding miraculous results. (Note: When both Zhong Re and Cold Damage present with a flooding pulse, the subtle difference—fine and rapid for Zhong Re versus other characteristics for Cold Damage—is critical and leaves no room for error. It requires careful discussion and personal comprehension.)
