温毒，是由于冬季气候异常温暖，人体感受了乖戾不正之气，到了春夏交替之时，又感受了温热之邪，潜伏的毒邪从体内向外发散，导致表里都出现热象。此外，还有风温、温病、冬温等病症，如果误用了辛温性质的药物，如同火上浇油，也能形成这种温毒疾病。其脉象浮取沉取均盛大有力，症状表现为心烦、发热、口渴、咳嗽、咽喉疼痛，舌质深红（绛），舌苔黄，适宜采用清热解毒的方法治疗，并加入甘草、桔梗来辅助治疗。然而，有的患者因温毒而出现了发斑、发疹、发颐（腮部肿胀）、喉肿等症状，这些情况不可不知。
大概温热毒邪深入阳明经，发于肌肉之间而形成斑疹，颜色鲜红表示胃热较轻，属于轻症；颜色紫暗表示热势严重，属于重症；颜色黑紫表示热极，病情危重；颜色鲜艳红润表示邪气外透，预后良好。当斑疹欲出未出之际，适宜用清凉透斑的方法治疗；如果斑疹发出后，患者神志昏蒙，需加入犀角、玄参进行治疗。《医宗心法》说：疹发于营分，营主血，所以颜色发红。《棒喝》说：邪气郁结不解，热邪进入血络而形成疹。疹也是红色为轻、紫色为重、黑色为危。虽然邪气郁结未解，热在营分，但温毒已经发于皮毛，这与斑在肌肉有很大区别。因为肺主皮毛，胃主肌肉，所以古人说斑属于足阳明胃病，疹属于手太阴肺病，界限分明，不容混淆。吴鞠通将二者混为一谈而未加区分，徐灵胎（虚谷）已经驳斥过他的错误，这确实是正确的观点。当疹子欲出未出之时，迅速使用辛凉解表的方法，加入生地黄、绿豆衣治疗；严重的加入青黛、连翘治疗。
又有温热毒邪，挟带少阳相火上攻，导致耳下硬肿疼痛，这是发颐的病证。发颐虽然归属于阳明经，但耳前耳后都是少阳经脉经过的地方，应当迅速消散，如果拖延则会化脓造成危害，适宜内服清热解毒法，去掉西洋参、麦冬，加入马勃、青黛、荷叶治疗；如果连面部都肿胀，加入白芷、漏芦；如果肿胀坚硬不消，加入穿山甲、皂角刺；外用仙花根，剥去赤皮和根须，放入臼中捣烂，敷在肿胀处，干了就更换，直到皮肤长出黍米大小的黄疮为止。
又有温热毒邪，向上发散，盘结于咽喉，形成肿痹。《内经》说：“一阴一阳结，谓之喉痹。”一阴指的是手少阴君火；一阳指的是手少阳相火。这两条经脉的脉络，都联络于咽喉，现在温毒聚集在这里，则君火和相火同时发作。大概火动则生痰，痰壅塞则肿胀，肿胀严重则闭塞不通，闭塞严重则会导致死亡。紧急使用玉钥匙散来开通咽喉，随后继以清热解毒法，去掉西洋参、麦冬，加入僵蚕、桔梗、牛蒡子、射干治疗。
Wendu (Warm Toxin) arises from abnormally warm weather in winter, where the human body contracts a perverse and chaotic pathogenic factor. By the transition between spring and summer, upon contracting additional warm-heat pathogens, the latent toxin erupts from within, resulting in heat affecting both the exterior and interior. Additionally, conditions such as Fengwen (Wind-Warmth), Wenbing (Warm Disease), and Dongwen (Winter-Warmth), if mistakenly treated with acrid-warm formulas, akin to adding fire to fire, can also result in this disease. The pulse is vigorous at both superficial and deep positions. Symptoms include mental restlessness, fever, thirst, cough, and sore throat; the tongue is crimson with a yellow coating. The appropriate treatment method is Clearing Heat and Resolving Toxicity (Qing Re Jie Du), supplemented with Gancao (Glycyrrhizae Radix et Rhizoma) and Jiegeng (Platycodonis Radix). However, one must be aware that Wendu may manifest as macules (Ban), papules (Zhen), parotid swelling (Fayi), or throat swelling.
Generally, when warm-heat toxin reaches the Yangming channel and manifests in the muscles, it forms macules. Red color indicates mild Stomach heat (light condition); purple indicates severe heat (heavy condition); black indicates extreme heat (critical condition); bright red indicates the pathogen is being expelled outward (auspicious prognosis). When macules are about to erupt but have not yet appeared, the treatment method of Cooling and Clearing to Transfuse Macules (Qing Liang Tou Ban) should be used. If macules appear accompanied by mental confusion, Xijiao (Rhinocerotis Cornu) and Yuanshen (Scrophulariae Radix) should be added. *Yizong Xinfa* states: "Papules arise in the Ying (Nutrient) level; Ying governs blood, hence the red color." *Banghe* states: "When pathogenic factors remain unresolved and heat enters the blood collaterals, papules form." Papules follow the same pattern: red is light, purple is heavy, black is critical. Although the pathogen remains unresolved and heat resides in the Ying level, the Wendu has manifested on the skin and hair (exterior), which differs significantly from macules located in the muscles. Since the Lung governs the skin and hair, and the Stomach governs the muscles, ancient practitioners stated that macules belong to the Foot-Yangming Stomach disease, while papules belong to the Hand-Taiyin Lung disease. Their boundaries are distinct and cannot be confused. Wu Jutong conflated them without distinction; Xu Lingtai (Xugu) has already refuted this error, which is indeed correct. When papules are about to erupt but have not yet appeared, rapidly apply the Acrid-Cool Exterior-Releasing method (Xin Liang Jie Biao), adding Sheng Dihuang (Rehmanniae Radix) and Lv Dou Yi (Phaseoli Semen Integrum). For severe cases, add Qingdai (Indigo Naturalis) and Lianqiao (Forsythiae Fructus).
Furthermore, warm-heat toxin may accompany Shaoyang Ministerial Fire attacking upward, causing hardness, swelling, and pain below the ears. This is Fayi (Parotitis). Although Fayi belongs to the Yangming channel, the areas anterior and posterior to the ear are traversed by the Shaoyang meridians. It must be dissipated quickly; otherwise, pus will form, causing harm. Internally, use the Clearing Heat and Resolving Toxicity method, removing Yangshen (American Ginseng Radix) and Maidong (Ophiopogonis Tuber), and adding Mabo (Calamitidis Spora), Qingdai (Indigo Naturalis), and Heye (Nelumbinis Folium). If the face is also swollen, add Baizhi (Angelicae Dahuricae Radix) and Loulu (Euphorbiae Humifusae Radix). If the swelling and hardness do not subside, add Shan Jia (Manis Squama) and Zao Ci (Gleditsiae Spina). Externally, use Xiannhua Gen (Narcissi Bulbi Radix), peel off the red skin and rootlets, pound into a paste in a mortar, and apply to the swollen area. Change it when dry, continuing until millet-sized yellow pustules appear on the skin.
Additionally, warm-heat toxin may ascend and knot in the throat, forming Zhongbi (Throat Obstruction). *Neijing* states: "The binding of one Yin and one Yang is called Hou Bi (Throat Bi)." One Yin refers to the Hand-Shaoyin Ministerial Fire; One Yang refers to the Hand-Shaoyang Ministerial Fire. The meridians of these two channels both connect to the throat. Now, with Wendu gathering here, both Ministerial Fires arise together. Fire generates phlegm; phlegm obstruction causes swelling; severe swelling causes obstruction; severe obstruction leads to death. Urgently use Yuyaochi (Jade Key Powder) to open the throat, followed by the Clearing Heat and Resolving Toxicity method, removing Yangshen (American Ginseng Radix) and Maidong (Ophiopogonis Tuber), and adding Jiangcan (Bombyx Batryticatus), Jiegeng (Platycodonis Radix), Niubangzi (Arctii Fructus), and Shegan (Belamcandae Rhizoma).
Wendu involves numerous variable manifestations. Since macules, papules, parotid swelling, and throat obstruction occur frequently, they are specifically highlighted here for clarification.
