春温汗出，微恶寒，头额痛，发热口渴，脉弦
长，此温邪在气。宜用杏仁、薄荷、连翘、葛根、大
力、菱皮，黑栀、桑叶、批杷叶等味，轻苦微辛，以
清气分也。
凡温症，犹伤寒初起，亦先伤阳经，而后传变，然伤寒
以六经见症为主，迨传变，而后更分营卫气血。温热则以营
卫气血为主，势已成，而后殊兼分六经见证。何也？伤寒先太
阳，次阳明、少阳，以次相传而后入阴。温热则太阳之后，
便传变无穷，若不先将营卫气血分晰辨明，如茫无畔岸，何
可背手。故种福堂（温热论）云：热邪上受，首先犯肺，逆
传心胞。又云：卫之后方言气，营之后方言血·聆此以权衡
营卫气血，最为切要。乃既汗后，微恶寒，发热额痛，口渴
脉长，此邪在阳明之表，卫外之邪既散，气分之热未清，欲
传之象已着。故用葛根、薄荷、桑叶、大力、枇杷叶开泄透
表，连翘、黑栀、萎皮、杏仁宜清肺气，使卫分气分之邪两
解，不致传入阳明之腑，而为斑黄狂妄也已。
春温汗后，头不痛，身热不恶寨，舌渐黄，咳嗽
协痛，脉弦数，此温邪犯肺。宜用杏仁、象贝、沙
参、桑叶、薄荷、萎皮、连翘、兜铃、枇杷叶等味，
轻扬宜肺也。
肺位最高，其象空虚，外彻卫表，内司气化。温邪初
起，首先犯肺，肺主气，其合皮毛。皮毛者，即卫表也。故
温邪之始，赤有头不痛，而仅见凛凛恶寒者。今汗后头不
痛，不恶寨，是皮毛表邪已透已泄，而惟身热舌黄，脉弦或
数，是内热未清，兼咳协痛，邪尚在肺，若不宜泄，必致传
陷·故用沙参，桑叶、杏仁、象贝、薄荷、连翘、兜铃、枇
杷叶，取气轻质薄之品，恰到肺位为度，非敢过清过表，而
反致缠绵焉。
春温病出现汗出、轻微恶寒、头额疼痛、发热口渴、脉象弦长，这是温邪在气分。适宜使用杏仁、薄荷、连翘、葛根、牛大力（此处指大力子/牵牛子或地方用药，依原文保留“大力”）、菱角皮、黑栀子、桑叶、枇杷叶等药物，性质轻苦微辛，以清解气分之热。
凡是温热病症，如同伤寒初起，也是先损伤阳经，然后发生传变。然而，伤寒以六经的见症为主，等到传变之后，才进一步区分营、卫、气、血。温热病则以营、卫、气、血为主，病情态势形成后，才兼有六经的见证。为什么呢？伤寒先由太阳经开始，依次传至阳明、少阳，再依次传入阴经。温热病则在太阳经之后，传变无穷无尽。如果不先将营、卫、气、血分析辨明，就会像茫茫大海没有边际一样，无法把握治疗方向。所以《种福堂瘟疫论》中说：热邪从上受入，首先侵犯肺脏，逆传心包。又说：卫分之后才谈到气分，营分之后才谈到血分。听到这些来权衡营、卫、气、血的关系，是最为切要的。既然已经发汗后，仍有轻微恶寒、发热、额头疼痛、口渴、脉象长，这是邪气在阳明经的表位，卫外的邪气虽然已散，但气分的余热未清，想要传变的迹象已经明显。因此使用葛根、薄荷、桑叶、牛大力、枇杷叶开泄透达表邪，使用连翘、黑栀子、瓜蒌皮、杏仁宜通肺气，使卫分和气分的邪气两相解除，不致使邪气传入阳明之腑，而出现发斑、发黄、狂妄等症状。
春温病发汗后，头部不痛，身体发热但不恶寒，舌苔逐渐变黄，咳嗽且胁肋疼痛，脉象弦数，这是温邪侵犯肺脏。适宜使用杏仁、象贝母、沙参、桑叶、薄荷、瓜蒌皮、连翘、款冬花、枇杷叶等药物，性质轻扬，宣利肺气。
肺的位置最高，其象空虚，外连卫表，内主气化。温邪初起，首先侵犯肺脏，肺主气，与皮毛相合。皮毛，就是卫表。所以温邪起始时，常有头不痛，仅见凛凛恶寒的情况。现在发汗后头不痛，也不恶寒，说明皮毛表邪已经透发宣泄，而只剩下身热、舌苔黄、脉象弦或数，这是内热未清，兼有咳嗽和胁肋疼痛，邪气仍在肺脏，如果不宣利宣泄，必定导致邪气内陷。因此使用沙参、桑叶、杏仁、象贝母、薄荷、连翘、款冬花、枇杷叶，选取气味轻薄之品，恰到好处地作用于肺脏部位，不敢过度清热或过度发汗，以免反而导致病情缠绵难愈。
Spring-warmth disease presents with sweating, slight aversion to cold, pain in the head and forehead, fever, thirst, and a wiry-long pulse. This indicates that warm pathogenic factors are in the Qi level (Qi Level). It is appropriate to use Apricot Seed (Xingren), Mint (Bohe), Forsythia (Lianqiao), Kudzu Root (Gegen), Qian Niu Zi (Da Li - *Note: Contextually likely referring to a specific herb like Pharbitis Seed or local usage, kept as Da Li*), Water Chestnut Peel (Lingpi), Black Gardenia (Hei Zhi), Mulberry Leaf (Sangye), and Loquat Leaf (Pipaye). These herbs are lightly bitter and slightly pungent, used to clear heat from the Qi level.
Generally, warm diseases, similar to the initial stage of Cold Damage (Shanghan), first injure the Yang meridians before transmitting. However, Cold Damage focuses on the manifestations of the Six Meridians (Six Jing), distinguishing Ying, Wei, Qi, and Blood levels only after transmission occurs. In contrast, warm diseases focus primarily on the Ying, Wei, Qi, and Blood levels; once the pathological trend is established, they then incorporate the manifestations of the Six Meridians. Why? Cold Damage begins with the Taiyang (Greater Yang) meridian, then transmits sequentially to Yangming (Yang Brightness) and Shaoyang (Lesser Yang), and finally enters the Yin meridians. Warm diseases, however, transmit infinitely after the Taiyang stage. If one does not first clearly distinguish and differentiate the Ying, Wei, Qi, and Blood levels, the treatment direction becomes boundless and ungraspable. Therefore, *Zhongfutang Wenre Lun* states: "Heat pathogens enter from above, first attacking the Lung, and may reversely transmit to the Pericardium." It also states: "After the Wei level, one discusses the Qi level; after the Ying level, one discusses the Blood level." Understanding these principles to weigh the relationships among Ying, Wei, Qi, and Blood is most crucial. After sweating, if there remains slight aversion to cold, fever, forehead pain, thirst, and a long pulse, this indicates the pathogen is at the exterior of the Yangming meridian. Although the external Wei-level pathogen has dispersed, the heat in the Qi level remains uncleared, and signs of further transmission are evident. Therefore, Gegen, Bohe, Sangye, Da Li, and Pipaye are used to open and vent the exterior; Lianqiao, Hei Zhi, Gualou Pi, and Xingren are used to benefit Lung Qi. This allows the pathogens in both the Wei and Qi levels to be resolved simultaneously, preventing the pathogen from transmitting to the Yangming Fu organs and causing macules, jaundice, or mania.
After sweating in spring-warmth disease, if the head no longer hurts, the body is hot without aversion to cold, the tongue coating gradually turns yellow, coughing is accompanied by hypochondriac pain, and the pulse is wiry and rapid, this indicates warm pathogens invading the Lung. It is appropriate to use Xingren, Xiang Bei Mu (Eleutherococcus Fruit/Bellflower Root variant, specifically Fritillaria Thunbergii), Shashen, Sangye, Bohe, Gualou Pi, Lianqiao, Doulouhua (Sonchus Flower), and Pipaye. These herbs are light and ascending, designed to ventilate and benefit Lung Qi.
The Lung resides at the highest position, its nature is empty and hollow, connecting externally to the Wei exterior and governing internal Qi transformation. When warm pathogens initially arise, they first attack the Lung. The Lung governs Qi and corresponds to the skin and hair. Skin and hair constitute the Wei exterior. Thus, at the onset of warm diseases, it is common to have no headache but only severe chills. Now, after sweating, with no headache and no aversion to cold, it indicates that the exterior pathogens in the skin and hair have been vented and released. The remaining symptoms—body heat, yellow tongue coating, and wiry or rapid pulse—indicate that internal heat remains uncleared. Accompanied by cough and hypochondriac pain, the pathogen still resides in the Lung. If not ventilated and released, it will inevitably sink inward. Therefore, Shashen, Sangye, Xingren, Xiang Bei Mu, Bohe, Lianqiao, Doulouhua, and Pipaye are used. These are selected for their light aroma and thin nature, acting precisely on the Lung's location. One dares not over-clear heat or over-ventilate the exterior, lest it cause the condition to linger and become chronic.
