中暑虽然常涉及太阳经，但也经常兼涉阳明经。大汗出、轻微恶寒发热属于太阳证；面红、大汗、烦躁口渴、气喘急促属于阳明证。病情重的患者，脉象可能洪大，甚至昏迷不省人事，症状类似热病，但区别在于病情忽轻忽重。治疗太阳证可用五苓散去桂枝加香薷；治疗阳明证可用消暑丸。
普通人偶然中暑，表现为身体发热、背部恶寒，出汗后肛门干燥且口渴，烦躁闷乱，痰气上逆恶心，或者呕吐腹泻、肌肉痉挛（转筋），小便闭塞涩痛，手指头微凉。这些情况都适宜使用五苓散去桂枝，配合益元散服用。
脾胃素来虚弱的人，上焦正气不足，暑湿之气郁结蒸腾，导致肢体困倦乏力，头重心烦，饱胀闷塞、气喘急促，感觉如同在烟雾中一般，早晚怕冷，日头升高时发热。这是气血俱虚的表现。适宜采用清暑益气的方法，可选用清燥汤。
暑天出汗过多，风邪侵入汗孔，导致身体沉重疼痛，四肢关节麻木昏沉，或者口渴或者不渴，或者小便黄赤涩痛。这是风邪郁闭、汗液湿气与暑邪相互搏结所致。适宜使用益元散加葱头。
长途跋涉或过度劳役，在大热天气下感到口渴，阳气内伏，热邪蕴结于肾，造成水不能制火，出现发热、烦躁口渴、气急喘促，傍晚时分症状减轻。这是脾胃极度虚弱的表现。适宜使用补中益气汤去掉升麻，加入麦冬、五味子、茯苓、泽泻、黄连、黄柏等药物。通过补益中气兼清解暑热，逐渐痊愈。
农夫在田野劳作，以及习惯从事体力劳动的人，过度受热熏灼，导致头角额头疼痛，发热、极度口渴想大量饮水，脉象洪大、大汗淋漓的，应立即制作地浆水，煎煮苍术白虎汤。
如果是年事已高以及体质虚寒的人，不宜使用寒凉药物的，可使用竹叶石膏汤，稍加熟附子以温通药性并引导药效运行。
如果是平素阴虚多火的人，不可使用温燥药物的，可使用白虎加人参竹叶汤。在酷暑时节，如果在道路上突然晕倒，难以服用汤药，担心气脱难以救治，应立即扶至阴凉处，不可卧于湿冷之地。捧取地上的热土敷在脐腹部，拨开中间使其形成空洞，让人在小洞中排尿，收集生姜或大蒜捣成的汁液，混合童便或热汤灌服。外用布蘸取液体擦拭身体，待患者苏醒后再用药调理。
Although heat-stroke (Shu Zhong) is often said to involve the Taiyang channel, it frequently also involves the Yangming channel. Profuse sweating with slight aversion to cold and fever characterizes a Taiyang pattern; red face, profuse sweating, irritability, thirst, and rapid breathing characterize a Yangming pattern. In severe cases, the pulse may be surging and large (Hong Da), or there may be coma and loss of consciousness, resembling heat diseases, but differing in that the severity fluctuates. For the Taiyang pattern, use Wuling San (Five-Ingredient Powder with Poria) minus Guizhi (Cinnamon Twig) plus Xiangru (Elsholtzia Herb); for the Yangming pattern, use Xiaoshu Wan (Summerheat-Dispelling Pill).
When a healthy person accidentally suffers from summerheat, symptoms include body heat, aversion to cold on the back, dryness and thirst at the anus after sweating, irritability and mental restlessness, rebellious phlegm and nausea, or vomiting, diarrhea, and muscle cramps (Zhuan Jin), closed and difficult urination, and slightly cold fingertips. All these conditions are suitable for treatment with Wuling San minus Guizhi combined with Yiyuan San (Benefit the Origin Powder).
For individuals with inherently weak Spleen and Stomach, where the Upper Jiao lacks sufficient Qi, summerheat-dampness stagnates and steams, leading to heavy and fatigued limbs, heavy head with irritability, fullness and oppression with rapid breathing, feeling as if in smoke, chills in the morning and evening, and heat when the sun is high. This indicates deficiency of both Qi and Blood. It is appropriate to clear summerheat and benefit Qi, selecting Qingzao Tang (Clear Dryness Decoction).
During summer, excessive sweating allows Wind pathogens to invade the sweat pores, causing heavy and painful body, numbness and dizziness in the joints, thirst or no thirst, or yellow and difficult urination. This is due to Wind stagnation and damp sweat contending with summerheat. It is suitable to use Yiyuan San plus Congtou (Scallion Head).
After long journeys or heavy labor in intense heat, accompanied by thirst, internal stagnation of Yang Qi, and heat lodging in the Kidney, resulting in Water failing to control Fire, symptoms include fever, irritability, thirst, rapid breathing, and shortness of breath, with symptoms alleviating in the late afternoon. This indicates severe deficiency of the Spleen and Stomach. It is suitable to use Buzhong Yiqi Tang (Tonify the Middle and Benefit Qi Decoction) minus Shengma (Cimicifugae Rhizoma), adding Maidong (Ophiopogonis Radix), Wuweizi (Schisandrae Fructus), Fuling (Poria), Zexie (Alismatis Rhizoma), Huanglian (Coptidis Rhizoma), and Huangbai (Phellodendri Cortex). Gradual recovery occurs through tonifying the middle while simultaneously clearing and resolving heat.
Farmers working in fields, and those accustomed to physical labor, who suffer excessive scorching heat, presenting with pain in the temples and forehead, fever, extreme thirst with desire to drink, surging pulse, and profuse sweating, should urgently prepare Dijiang Shui (Earth Slurry Water) and decoct Cangzhu Baihu Tang (Atractylodes White Tiger Decoction).
For the elderly or those with deficient-cold constitutions who should not use cold-natured herbs, Zhuye Shigao Tang (Bamboo Leaf and Gypsum Decoction) is suitable, with a slight addition of Shu Fuzi (Prepared Aconite Lateral Root) to warm and guide the action.
For those with inherent Yin deficiency and excess fire, who cannot tolerate warming herbs, Baizhu Jia Renshen Zhuye Tang (White Tiger Decoction Plus Ginseng and Bamboo Leaf Decoction) is used. During intense summer heat, if someone collapses suddenly on the road and herbal decoctions are inconvenient to administer, fearing irreversible Qi collapse, immediately move them to a cool, shady place, avoiding lying on wet or cold ground. Scoop up hot earth from the ground and place it on the umbilicus and abdomen, creating a small hollow in the center, and have someone urinate into it. Collect juice from crushed fresh ginger or garlic, mix with child's urine or hot water, and force-feed. Externally, wipe the body with cloth soaked in the liquid, and administer medication only after the patient regains consciousness.
