凡是温病发作，必然出现口渴、心烦意乱的症状，伴有胁肋部胀满、口苦，怕热而不怕冷。这明确显示病邪是从体内发出的，完全没有表证（体表受邪的证候）。虽然涉及的经络不同，但病邪必定先涉及少阳经，这是因为春季风气主令，对应五行中的木行。
第一种治法：如果是少阳病与阳明病合病，且里证（脏腑内部的热实证）较多的情况，使用承气汤。
第二种治法：如果是三阳经（太阳、阳明、少阳）合病，使用大柴胡汤，或者双解散。
第三种治法：如果少阳经受外邪侵袭而发病，脉象弦细，两侧额角旁疼痛，寒热往来、口苦，适宜用小柴胡汤去掉人参、生姜、半夏，加入栝蒌根（天花粉）。如果有呕吐症状，只需去掉人参。
第四种治法：如果脉象微紧，兼有怕冷、头痛，适宜用栀子豉汤，或者益元散加入葱白、豆豉、薄荷。如果热势很盛，用凉膈散，去掉大黄、朴硝，加入葱白、豆豉。
第五种治法：如果头痛剧烈如要破裂，这是突然感受外邪所致，适宜用葛根葱白汤。在疏散邪气之后，再用黄芩汤调理。
第六种治法：如果脉象洪大而数，体外发热并伴有胡言乱语，说明热邪在三焦，使用三黄石膏汤。
第七种治法：凡是应当使用下法（泻下通便）的证候，在使用下法后热势不退，或者暂时缓解后又发热，可以再次使用下法。
第八种治法：使用下法后热势仍不止，脉象涩滞，咽喉疼痛，胸部胀满，多汗，这是热邪损伤了血分，应用葶苈苦酒汤通过催吐的方法治疗。
第九种治法：如果体内热势已经很盛，阳热邪气郁结在内，导致身体躁动却无法出汗，即使还没有完全具备使用下法的指征，也适宜用凉膈散。
第十种治法：如果腹部胀满、心烦口渴，脉象沉实有力，选用三承气汤中的一种。如果病情危急严重，则配合黄连解毒汤使用。
第十一种治法：倘若温病中少阴经潜伏的病邪发出，又同时感受了太阳经的外邪，这种病症称为风温。此时阳脉（寸脉）浮滑，阴脉（尺脉）濡弱，出现发热、咽喉疼痛、口苦，只是轻微怕冷的情况，使用黄芩汤，加入桂枝、石膏。或者先用葱白、豆豉疏散体表的邪气，然后再用黄芩汤。如果病情严重，则对葳蕤汤进行加减化裁使用。
第十二种治法：原本是太阳病，出现发热且口渴，医生误用了发汗法，导致身体灼热烫手，这也称为风温。此时寸关尺三部脉象都浮，如同前文所述的证候，使用麻黄升麻汤，去掉麻黄、升麻、生姜、白术。按：对于因误用发汗而导致的风温这一证候，张仲景没有给出方剂，是因为认为这是太阳病和少阴病同时发作，比两感证（阴阳两经同时受邪）更危险，离康复非常遥远。
Whenever warm diseases manifest, there must be thirst and restlessness, distension in the hypochondrium, bitter taste in the mouth, aversion to heat but not aversion to cold. This clearly indicates that the pathogen originates from within, with no exterior syndrome (a pattern caused by external pathogens affecting the body surface). Although different meridians may be involved, the Shaoyang meridian is invariably affected first, as spring governs the wind element corresponding to Wood in the Five Elements.
Method 1: In cases of combined Shaoyang and Yangming diseases where interior syndromes (heat excess patterns involving internal organs) predominate, Chengqi Tang (Cathartic Decoction) is indicated.
Method 2: In cases of combined Three-Yang diseases (Taiyang, Yangming, and Shaoyang), Da Chaihu Tang (Major Bupleurum Decoction) or Shuangjie San (Double-Release Powder) may be used.
Method 3: If the Shaoyang meridian is invaded by an exogenous pathogen leading to disease, characterized by a wiry pulse, pain on both sides of the forehead, alternating chills and fever, and bitter taste, Xiao Chaihu Tang (Minor Bupleurum Decoction) should be modified by removing Renshen (Ginseng Root), Shengjiang (Fresh Ginger), and Banxia (Pinellia Tuber), and adding Gualou Gen (Trichosanthes Root). If vomiting is present, only remove Renshen.
Method 4: If the pulse is slightly tight, accompanied by aversion to cold and headache, Zhizi Chi Tang (Gardenia and Fermented Soybean Decoction) or Yi Yuan San (Benefit Origin Powder) added with Congbai (Scallion White), Douchi (Fermented Soybean), and Bohe (Mint Leaf) is suitable. If the heat is severe, Liangge San (Cool the Diaphragm Powder) is used, removing Dahuang (Rhubarb Root) and Poxiao (Mirabilite), and adding Congbai and Douchi.
Method 5: If the headache is excruciating as if the head were splitting, due to sudden contraction of exogenous pathogens, Gegen Congbai Tang (Kudzu and Scallion Decoction) is indicated. After dispersing the pathogen, Huangqin Tang (Scutellaria Decoction) should be administered.
Method 6: If the pulse is surging and rapid, with external fever and delirious speech, the heat resides in the Triple Burner; Sanhuang Shigao Tang (Three-Yellow and Gypsum Decoction) is indicated.
Method 7: For any syndrome requiring purgation, if the heat persists after purgation, or temporarily subsides and then returns, purgation may be repeated.
Method 8: If the heat continues after purgation, accompanied by a choppy pulse, sore throat, chest fullness, and profuse sweating, this indicates heat damaging the Blood level. Tingli Kujiu Tang (Descurainia and Vinegar Decoction) should be used to induce vomiting.
Method 9: If interior heat is extremely severe, with Yang pathogenic factors constrained internally, causing agitation without the ability to sweat, even if the indications for purgation are not fully met, Liangge San (Cool the Diaphragm Powder) is appropriate.
Method 10: If abdominal fullness, restlessness, and thirst are present with a deep and solid pulse, one of the three Chengqi Tang formulas should be selected. If the condition is critical, it should be combined with Huanglian Jiedu Tang (Coptis Detoxification Decoction).
Method 11: If latent pathogens in the Shaoyin meridian emerge in warm diseases, and are simultaneously exposed to Taiyang exogenous pathogens, this condition is called Fengwen (Wind-Warmth). The Yang pulse (Cun position) will be floating and slippery, and the Yin pulse (Chi position) will be soft and weak. Symptoms include fever, sore throat, bitter taste, and slight aversion to cold. Huangqin Tang (Scutellaria Decoction) added with Guizhi (Cinnamon Twig) and Shigao (Gypsum) is indicated. Alternatively, use Congbai and Douchi first to release the exterior, followed by Huangqin Tang. In severe cases, Weirui Tang (Polygonatum Decoction) should be modified.
Method 12: Originally a Taiyang disease presenting with fever and thirst, if mistakenly treated with diaphoresis (sweating method), resulting in burning hot skin, this is also termed Fengwen (Wind-Warmth). The pulses at all positions (Yin and Yang) will be floating as described previously. Mahuang Shengma Tang (Ephedra and Asarum Decoction) should be used, removing Mahuang (Ephedra Herb), Shengma (Cimicifuga Rhizome), Jiang (Ginger), and Zhu (Atractylodes Rhizome). Note: Regarding the Fengwen syndrome caused by erroneous diaphoresis, Zhang Zhongjing did not provide a formula because he considered it a simultaneous attack of Taiyang and Shaoyin, which is more dangerous than Lianggan (simultaneous invasion of Yin and Yang meridians) and has a very poor prognosis.
