以少阴主内，水寒上入，即从少阴温经散寒之法而施治也。所以方下云“当汗出如虫行皮中

治疗气分病，表现为胃脘部坚硬，大如盘状，边缘像倒扣的杯子，这是由水饮邪气所致。
使用桂枝去芍药汤与麻黄附子细辛汤合方。用水七升，先煮麻黄，去除浮沫，然后加入其余药物，煎煮至二升，分三次温服。
应当通过发汗来治愈。
桂枝麻黄附子细辛汤，去掉芍药原本就是复方。胃脘部感觉像盘子一样坚硬且大的情况，是因为水寒之邪结聚于此，此方能将其驱散。另外有枳术汤这一方剂（枳术汤也治疗这种证候，歌诀另行编写），其治法区分了阴阳，义理更加彰显。（喻嘉言认为“心下”即胃的上部。胃中阳气不能布散，心下就被水饮的阴邪占据，虽然总归是阳气职权不伸所致，但存在阴阳两种证候表现。如果是阳气虚弱而阴气乘虚侵袭，结聚在心下，必须用桂枝汤去掉芍药的酸寒之性，加上麻黄、附子、细辛，共同驱散胸中的水寒之邪。因为少阴经主内，水寒之邪从内部上入，就采用温通少阴经、散发寒邪的方法进行治疗。所以方剂说明中说“当出汗时感觉像虫子在皮肤中爬行那样就会痊愈”，由此可见胃中的阳气不能布散，意味着胸中的阳气也虚弱；胸中阳气虚弱，连护卫体表的阳气也不固密，所以出汗时感觉像虫子在皮肤中爬行，这仍然显示出阳气运行滞涩的现象。如果不是桂枝、麻黄、细辛、生姜协同附子的强大力量，心下的水寒之邪能消散并走向皮下吗？水寒之邪消散后，原来坚硬的部位就会豁然变空。那些阳热邪气自行结聚在阳位，阴寒之邪尚未上入体内的，只需使用枳实、白术两味药，开通痰结，健运脾胃，那么阳分中的阳热邪气，解除起来就容易了。《金匮要略》虽然没有明确说明，但终究气分的水饮病，离不开这两种阴阳治法。）
治疗伤寒病程六七天，出现发热、轻微怕冷，肢体关节烦扰疼痛，轻微呕吐，胃脘部有支撑感且结聚，表证仍未解除的情况。
柴胡（四两） 黄芩 人参 桂枝 芍药 生姜（各一两半） 甘草（一两） 半夏（二合半）
小柴胡汤与桂枝汤合方（名为柴胡桂枝汤），这是治疗太阳、少阳两经合病的方剂。两方合用能起到调和营卫、通畅津液的作用（两汤合用的功效如此）。肢体关节烦疼属于太阳证，痞闷呕吐属于少阳证，服用此方可使症状康复。对于太阳病热重寒轻者，若脉象微弱、阳气微虚，适宜用此方匡正治疗。阳气微虚切勿再次强力发汗，误用发汗会损伤津液和阳气，导致亡阳。（太阳病热多寒少，脉弱无阳的证候，张仲景主张用桂枝二越婢一汤。柯韵伯说：“脉弱阳微，不可发汗，怎么能再用麻黄、石膏，严重耗竭阳气呢？仔细审察证候选用方剂，只有柴胡桂枝汤最为恰当。”）
Treats Qi-level disease, presenting with hardness in the epigastrium (upper abdomen), large as a plate, with edges resembling an inverted cup, caused by fluid retention (water-drink).
Combine Guizhi Qu Shaoyao Tang (Cinnamon Twig Decoction without Paeonia) and Mahuang Fuzi Xixin Tang (Ephedra, Aconite, and Asarum Decoction). Use seven sheng of water, boil Mahuang (Ephedrae Herba) first to remove the foam, then add the remaining herbs, boil until two sheng remain, divide into three warm doses.
It should be cured through sweating.
Guizhi Mahuang Fuzi Xixin Tang, originally a compound formula after removing Shaoyao (Paeoniae Radix). When the epigastrium feels hard and large like a plate, this decoction can dispel the accumulation of cold-fluid here. Another prescription is Zhizhu Tang (Immature Bitter Orange and Atractylodes Macrocephala Decoction) (Zhizhu Tang also treats this syndrome; its verse is compiled separately); its method distinguishes Yin and Yang, making the principle even more clear. (Yu Jiayan stated that "epigastrium" refers to the upper part of the Stomach. When Yang Qi of the Stomach fails to distribute, the epigastrium is occupied by the Yin of fluid retention. Although it is ultimately due to the failure of Yang Qi's authority to extend, there are two distinct presentations of Yin and Yang. If Yang Qi is deficient and Yin pathogen takes advantage to invade, knotting in the epigastrium, one must use Guizhi Tang removing the sour-cold nature of Shaoyao, and add Mahuang (Ephedrae Herba), Fuzi (Aconiti Lateralis Radix Praeparata), and Xixin (Asari Radix et Rhizoma) to jointly disperse the cold-fluid in the chest. Since the Shaoyin channel governs the interior, when cold-fluid enters from the interior upwards, treatment follows the method of warming the Shaoyin channel and dispersing cold. Hence, the note under the formula states "when sweat comes out feeling like insects crawling on the skin, then recovery occurs," showing that if Stomach Yang cannot distribute, Chest Yang is also deficient; if Chest Yang is deficient, the defensive Yang protecting the exterior is also insecure. Thus, when sweating, the sensation of insects crawling on the skin still reveals the image of sluggish Yang Qi. Unless Gui Zhi (Cinnamomi Ramulus), Ma Huang (Ephedrae Herba), Xi Xin (Asari Radix et Rhizoma), and Sheng Jiang (Zingiberis Rhizoma Recens) cooperate with the great power of Fu Zi (Aconiti Lateralis Radix Praeparata), how could the cold-fluid in the epigastrium disperse and move to the subcutaneous tissue? Once the cold-fluid disperses, the previously hard and large area becomes hollow. For cases where Yang-heat pathogen knots itself in the Yang position, and Yin-cold has not yet entered upwards, simply using Zhi Shi (Immaturus Citri Grandis Fructus) and Zhu Bai (Atractylodis Macrocephalae Rhizoma) opens phlegm-knots and strengthens the Spleen and Stomach, making the resolution of Yang-heat in the Yang portion easy. Although the *Jin Gui Yao Lue* does not explicitly state this, ultimately, fluid diseases at the Qi level do not exceed these two treatments of Yin and Yang.)
Treats Taiyang-Shaoyang combined disease occurring six or seven days after contracting Cold Damage, presenting with fever, slight aversion to cold, vexing pain in the limbs and joints, slight vomiting, support and knotting in the epigastrium, and unresolving exterior symptoms.
Chai Hu (Four liang), Huang Qin (Scutellariae Radix), Ren Shen (Ginseng Radix et Rhizoma), Gui Zhi (Cinnamomi Ramulus), Shao Yao (Paeoniae Radix), Sheng Jiang (Zingiberis Rhizoma Recens) (each one and a half liang), Gan Cao (Licorice Radix et Rhizoma) (one liang), Ban Xia (Pinelliae Tuber) (two he and a half).
Xiao Chai Hu Tang (Minor Bupleurum Decoction) combined with Guizhi Tang (Cinnamon Twig Decoction) (named Chai Hu Gui Zhi Tang), this is a formula for Taiyang-Shaoyang combined disease. The combination of these two decoctions achieves harmonizing Ying and Wei (nutritive and defensive levels) and unblocking Jin Ye (body fluids). Vexing pain in limbs and joints belongs to Taiyang syndrome; fullness and vomiting belong to Shaoyang syndrome, and health is restored. For Taiyang syndrome with heavy heat and light cold, if the pulse is weak and Yang is slightly deficient, this formula is suitable for correction. Do not induce heavy sweating when Yang is slightly deficient; mistaken sweating will damage Jin Ye and Yang, leading to collapse of Yang. (For Taiyang syndrome with much heat and little cold, and a weak pulse indicating absence of Yang, Zhang Zhongjing advocates using Guizhi Er Yuebi Yi Tang (Cinnamon Twig Twice Yuebi One Decoction). Ke Yunbo said: "With a weak pulse and deficient Yang, sweating is contraindicated; how could one use Ma Huang (Ephedrae Herba) and Shi Gao (Gypsum Fibrosum) again, severely exhausting Yang? Carefully examining the syndrome to select the formula, only Chai Hu Gui Zhi Tang is most appropriate.")
