治疗在阳分的病证，应当用发汗的方法解除。如果反而用冷水喷洒或浇灌它，体内的热邪被遏制而不能发散，会更加烦闷不安，皮肤上出现鸡皮疙瘩（肉起），想要喝水却并不觉得口渴的，服用文蛤散。如果服药后病不愈的，给予五苓散。如果是寒实结胸且没有热象表现的，给予三物小陷胸汤。白散也可以服用。
文蛤（五两）
以上一味药研成散剂。用沸水调和一方寸匕的药量服用。用水五合。
歌诀曰：用水喷洒原本超越了发汗的法度。（太阳病适宜发汗却用水喷洒。）皮肤出现粟粒状突起（水气停留在皮肤表面）。更加增加烦闷感。（热邪郁结在内）
男元犀按语：太阳病如果不发汗而用水喷洒，导致在表的阳气反而退却入内而不能外出。老师选用文蛤制成散剂。
后来，如果有口渴想喝水并且贪饮的情况，用文蛤汤主治。同时也主治微风、脉紧、头痛。仔细辨证使用方剂，那么前面用的是散剂，这里用汤剂更为适宜。附上文蛤汤方：文蛤五两，麻黄、甘草、生姜各三两，石膏五两，杏仁五十枚，大枣十二枚。用水六升，煮取二升，温服一升，出汗即痊愈。
张令韶说：前面的论述中，内因的水邪结聚于胸胁而形成大陷胸汤证；这里的论述是外因的水邪进入皮肤而导致皮肤出现粟粒状突起。或者解其热，或者用辛热药物来疏散外寒，根据时机制宜，没有不可以的。
桔梗（三分） 贝母（三分） 巴豆（一分，去皮心，熬黑，研如脂状。）
以上两味药研成散剂，加入巴豆，再在臼中捣匀。用米汤调和服用。体质强壮的人服半钱匕，体弱的人减量。病位在膈上的，必然会引起呕吐。
其余人浅注全录之。（此照内台方及张氏本节之。）
歌诀曰：巴豆熬熟后研磨像油脂一样。只需一分（去声）遵守成规。再加上桔梗和贝母各三分（去声）。寒实结胸要仔细辨别医治。
蔚按语：巴豆性味辛热，能疏散寒实并破除水饮。贝母开通胸中结滞，桔梗宣开肺气。不做汤剂而做散剂，是取“散剂以消散病邪”的意思。喝热粥，是为了帮助巴豆的热势以推动药力运行。喝冷粥，是为了制约巴豆的热势以停止药效。
Treating diseases in the Yang aspect should be resolved through sweating. If one instead sprays or irrigates with cold water, the heat is constrained and cannot escape, leading to increased restlessness. The flesh rises (skin becomes goosefleshed). If there is a desire to drink water but no actual thirst, administer Wenli San (Clam Shell Powder). If it does not resolve, administer Wuling San (Five-Ingredient Powder with Poria). For Cold-Excess Jie-Xiong (Chest Binding) without Heat signs, administer Sanwu Xiaoxiongtang (Three-Ingredient Minor Chest-Piercing Decoction). Baisan (White Powder) may also be administered.
Wenli (Halitum Arcae, Clam Shell) (five liang)
Take the above single ingredient, grind into powder. Mix with boiling water and take one fangcun bi (a square-inch measure) as a dose. Use five he of water.
Song says: Using cold water spray originally exceeds the method of sweating. (Taiyang disease should be treated by sweating, but was sprayed with water.) Gooseflesh appears in the skin (Water resides in the skin). Increasing restlessness further. (Heat is constrained and internalized).
Nan Yuanxi notes: In Taiyang disease, if sweating is not induced but cold water is sprayed, the Yang Qi at the exterior retreats inward and cannot exit. The Master selects Wenli to make a powder.
Later, if there is thirst desiring water and greedy drinking, Wenli Tang (Clam Shell Decoction) is the main treatment. It also treats mild wind, tight pulse, and headache. Examining the syndrome to use the formula, then that case used powder while this one uses decoction, which is more appropriate. Attached is Wenli Tang: Wenli five liang, Mahuang (Ephedrae Herba), Gancao (Glycyrrhizae Radix et Rhizoma), Shengjiang (Zingiberis Rhizoma Recens) each three liang, Shigao (Gypsum Fibrosum) five liang, Xingren (Armeniacae Semen Amarum) fifty seeds, Dazao (Jujubae Fructus) twelve pieces. Boil in six sheng of water to obtain two sheng. Take one sheng warm. Sweating indicates cure.
Zhanglingshao said: The previous discussion involved internal Water binding in the chest and hypochondrium forming the Daxiantang (Major Chest-Piercing Decoction) syndrome. This discussion involves external Water entering the skin causing gooseflesh. One may clear its heat, or use acrid-hot herbs to disperse external cold. Adapting to the time and situation, nothing is inadvisable.
Jiegeng (Platycodonis Radix) (three fen) Beimu (Fritillariae Bulbus) (three fen) Badou (Crotonis Fructus) (one fen, remove peel and heart, roast until black, grind like fat.)
Take the above two ingredients, grind into powder. Add Badou. Further pound in a mortar. Mix with Baiyin (white rice gruel) and take. Strong individuals take half a qianbi; frail individuals reduce the dose. If the disease is above the diaphragm, vomiting will necessarily occur.
Yu Qianzhu fully records it. (This follows Neitai Fang and Zhang's section here.)
Song says: Badou roasted and ground resembles fat. Only need one fen (qù shēng - falling tone) to keep the established rule. Add Jiegeng and Beimu equally at three fen (qù shēng - falling tone). Carefully differentiate for Cold-Excess Jie-Xiong.
Wei notes: Badou is acrid and hot, capable of dispersing Cold-Excess and breaking Water-Drink. Beimu opens chest binding, Jiegeng opens Lung Qi. Not making a decoction but making a powder takes the meaning of "using powder to scatter/disperse." Drinking hot porridge assists Badou's heat to promote movement. Drinking cold porridge restricts Badou's heat to stop action.
