冬温烦热不解，口渴，舌黄尖赤，脉洪或数，此
邪传阳明气分。宜用白虎汤加杏仁、沙参，桑叶，连
翘等味，清胃透邪也。
肺邪不解，而致口渴，舌黄尖赤，脉洪或数，此邪已到
阳明气分。夫阳明者胃也，凡肺邪不解，必传于胃，然阳明
亦得气血之分。今口渴脉洪，舌苔带黄，是为气热，故用石
膏、知母，合沙参、连翘，直清阳明;甘草、粳米、甜杏、
桑叶，甘凉养津。若见舌绎或黑，烦热口渴，神昏妄笑，是
为血分。宜用犀角地黄汤凉之。当与仲景《伤寒例》中阳明
经病腑病、气分血分，逐一辨明，方可下手，否则如涉海问
津矣。
冬温烦热神昏，舌赤苔黄，口渴咳嗽，斑疹脉
数，此邪在肺胃。宜用沙参、连翘、元参、石膏、甜
杏、川贝，桑叶、大力、人中黄，牛黄丸等味，清气
透斑也。
热渐传营，神昏口渴，咳嗽斑疹，是邪在肺胃之间，非
从气分清解，则斑疹难透。夫斑为阳明热毒，疹为太阴风
热，斑疹俱见，二经受病。故用沙参、连翘、元参、石膏、
甜杏、川贝、大力、中黄清气热，兼牛黄丸芳香宜窍也。
冬温热甚，烦躁口渴，舌绎苔黄，神昏谵语，斑
疹隐约，此邪热传营。宜用羚羊角、连翘、元参、沙
参、鲜生地、鲜石斛、鲜菖蒲、广郁金、石膏、牛
黄丸、青竹叶等味，清营转气也。
热不解而烦躁口渴，舌绛苔黄，里热已甚;更兼神昏谵
妄，斑疹隐约，乃邪已入营，若再不解，必延入血。故用羚
羊角、连翘、元参、沙参、鲜生地、石斛、鲜菖蒲两清气
血，佐以牛黄丸芳香宣窍，使其从营转气，由气达表，尚可
一汗而解。凡舌苔黄白，间杂浮腻，尖虽鲜绎，神虽昏谵，
总为气热未清，不可专凉血分，恐致气分之邪无由出路，徒
增险态，设不得已，惟宜两清之可也。
In winter-warmth disease, if vexatious heat persists and is not resolved, accompanied by thirst, yellow tongue coating with a red tip, and a surging or rapid pulse, this indicates that the pathogenic factor has transmitted to the Qi level of the Yangming channel. It is appropriate to use Baihu Tang (White Tiger Decoction) added with Xingren (Almond), Shashen (Glehniae Radix), Sangye (Mulberry Leaf), Lianqiao (Forsythiae Fructus), etc., to clear the Stomach heat and vent the pathogen.
If the pathogen in the Lung fails to resolve, leading to thirst, yellow tongue coating with a red tip, and a surging or rapid pulse, this also signifies that the pathogen has reached the Qi level of the Yangming channel. The term "Yangming" refers to the Stomach. Whenever the pathogen in the Lung does not resolve, it must transmit to the Stomach; however, the Yangming channel is also divided into Qi and Blood levels. Currently, the presence of thirst, surging pulse, and yellowish tongue coating indicates heat in the Qi level. Therefore, Shigao (Gypsum Fibrosum) and Zhimu (Anemarrhenae Rhizoma) are used in combination with Shashen and Lianqiao to directly clear Yangming heat; Gancao (Licorice Root), Jingmi (Glutinous Rice), Tianxingren (Sweet Almond), and Sangye employ sweet and cool properties to nourish body fluids. If a crimson tongue with cracks or blackening is observed, along with vexatious heat, thirst, coma, and delirious laughter, this indicates the pathogen has entered the Blood level. It is appropriate to use Xijiao Dihuang Tang (Rhinoceros Horn and Rehmannia Decoction) to cool the blood. One should carefully distinguish these conditions from the discussions on Yangming meridian disease, fu-organ disease, Qi level, and Blood level in Zhang Zhongjing's *Treatise on Cold Damage* (*Shanghan Lun*), before initiating treatment; otherwise, it would be like navigating the sea without knowing the ferry crossing.
In winter-warmth disease, if there is vexatious heat, coma, crimson tongue with yellow coating, thirst, cough, macules and papules, and a rapid pulse, this indicates the pathogen is located in the Lung and Stomach. It is appropriate to use Shashen, Lianqiao, Xuanshen (Scrophulariae Radix), Shigao, Tianxingren, Chuanbeimu (Fritillariae Cirrhosae Bulbus), Sangye, Niubangzi (Arctii Fructus), Renzhonghuang (Human Manure), and Angong Niuhuang Wan (Calculus Bovis Pill for Opening the Orifices), etc., to clear Qi-level heat and vent the macules and papules.
As heat gradually transmits to the Ying (Nutrient) level, symptoms such as coma, thirst, cough, and macules/papules appear, indicating the pathogen is between the Lung and Stomach. If one does not clear and resolve from the Qi level, the macules and papules will be difficult to vent. Macules are caused by heat-toxin in the Yangming channel, while papules are caused by wind-heat in the Taiyin channel. When both macules and papules appear simultaneously, it indicates that both channels are affected. Therefore, Shashen, Lianqiao, Xuanshen, Shigao, Tianxingren, Chuanbeimu, Niubangzi, and Renzhonghuang are used to clear Qi-level heat, combined with Angong Niuhuang Wan to open the orifices with aromatic properties.
In winter-warmth disease, if the heat is severe, accompanied by restlessness, thirst, crimson tongue with yellow coating, coma, delirium, and faintly visible macules/papules, this indicates the pathogenic heat has transmitted to the Ying level. It is appropriate to use Lingyangjiao (Saiga Tataricae Cornu), Lianqiao, Xuanshen, Shashen, Xian Shengdi (Fresh Rehmanniae Radix), Xian Shihu (Fresh Dendrobii Caulis), Xian Changpu (Fresh Acori Tatarinowii Rhizoma), Guang Yujin (Curcumae Radix), Shigao, Angong Niuhuang Wan, and Qingzhuyez (Bamboo Leaves), etc., to clear the Ying level and transform the pathogen back to the Qi level.
If the heat does not subside and is accompanied by restlessness and thirst, with a crimson tongue and yellow coating indicating severe internal heat; further compounded by coma and delirium, and faintly visible macules/papules, this shows the pathogen has entered the Ying level. If not resolved promptly, it will inevitably extend into the Blood level. Therefore, Lingyangjiao, Lianqiao, Xuanshen, Shashen, Xian Shengdi, Shihu, and Xian Changpu are used to simultaneously clear the Qi and Blood levels, assisted by Angong Niuhuang Wan to aromatically ventilate the orifices, allowing the pathogen to transform from the Ying level to the Qi level, and from the Qi level to reach the exterior, where it can potentially be resolved through sweating. Generally, if the tongue coating is yellow and white mixed with floating greasiness, and although the tip is fresh crimson and the patient is comatose and delirious, it is still fundamentally due to uncleared Qi-level heat. One must not exclusively use blood-cooling herbs, lest the Qi-level pathogen lose its exit route, merely increasing the severity of the condition. In unavoidable cases, only simultaneous clearing of Qi and Blood is suitable.
