三承气汤（见《伤寒论》
左归饮（方见头痛） 此方加生地、当归，能滋阳明之阴，以去胃口伏邪之燥火，去茯苓者

水煎服。
此方妙在生姜之辛温以利气，气化则水行矣。时医疑生姜发汗，而以干姜代之，岂知干
姜守而不走，大失此方之本旨。若再炮黑，或加肉桂，更为无知妄作矣。

大半夏汤
半夏（洗去涎，六钱） 人参（三钱） 白蜜（八钱
水三杯半，和蜜扬二百四十遍，煎八分服。
此方用水之多，取其多煮白蜜，去其寒而用其润，俾粘腻之性，流连于胃，不速下行，
而半夏人参之力，可以徐徐斡旋于中，非参透造化之理者，不能悟及。隔咽之间，交通之气
不得降者，皆冲脉上行，逆气所作也。冲脉不治，取之阳明，仲景以半夏降冲脉之逆，即以
白蜜润阳明之燥，加人参以生既亡之津液，用甘澜水以降逆上之水饮，古圣之经方，惟仲景
能用之。

安肾丸 治肾气不足，饭后即泄。又《金匮翼》云∶“喘因肾虚，气吸不下者，或因气
自小腹下起而上逆者，但经微劳，或饥时即发，宜以六味补阴之属，壮水配火。若足冷面热
者，须以安肾之属，导水归元。”

肾气不足，故用温补诸药以安之。方中桃仁、萆 、蒺黎三味，非思议可及，方意与
八味地黄丸同。但八味地黄丸长于利水，未免减其温补之力，而此则用专而力更大也。

以上药物研为细末，用炼蜜调和制成丸剂，大小如梧桐子，每次服用二十丸，临睡前用温水送服，大便通畅即停止服药。
按语：权量和尺寸的标准古今不同，此方各家折算比例不一，无法统一。
三承气汤（见《伤寒论》）
左归饮（方剂见头痛章节） 此方加入生地、当归，能够滋养阳明经的阴液，以清除胃口中潜伏邪气的燥火；去掉茯苓，是担心其药力旁流入肾（坎），不如专门顾护阳明经来得迅速有效。
三一承气汤（见瘟疫章节） 附子理中汤（即理中汤加入附子）
真武汤 治疗少阴病引起的呕吐逆气、腹痛、小便短少，以及治疗一切水饮病症。
云茯苓 白芍 生姜（各三钱） 白术 附子（各二钱）
用水煎服。
此方的妙处在于生姜的辛温性质能够利气，气机通畅则水液运行。当时的医生怀疑生姜会发汗，而用干姜代替，哪里知道干姜性质守而不走，完全失去了此方原本的宗旨。如果再将其炮黑，或者加入肉桂，更是无知妄为了。
吴茱萸汤（见上文头痛章节） （大、小）柴胡汤 五泻心汤（均见《伤寒论》）
越鞠丸（朱丹溪创制） 治疗各种郁证。
香附 苍术 抚芎（川芎的一种） 栀子 六神曲（各等分） 或制成丸剂或煎汤服用，视情况而定。
大半夏汤
半夏（洗去涎沫，六钱） 人参（三钱） 白蜜（八钱）
水三杯半，与蜂蜜混合，扬动二百四十遍，煎至八分，服用。
此方用水较多，是为了多煮白蜜，去除其寒性而利用其润燥之效，使粘腻的性质在胃中停留，不迅速下行，从而让人参和半夏的药力可以在中焦徐徐运转，不是透彻造化道理的人，不能领悟到这一点。咽喉之间，交通的气机不能下降的，都是冲脉上行，逆气作祟所致。冲脉的病不治，取法于阳明经，张仲景用半夏来降冲脉的逆气，同时用白蜜滋润阳明经的燥热，加入人参以生发已经亡失的津液，使用甘澜水来降低上逆的水饮，古代圣人的经典方剂，只有张仲景能运用得当。
不换金正气散 杨仁斋说：“脾气虽然强盛，但肾气不足，所以饮食咽下后，大肠就会发生完谷不化的泄泻，应煎服不换金正气散，吞服安肾丸。”
苍术（淘米水浸泡） 陈皮（各二钱半） 浓朴（姜汁制，二钱） 甘草（蜜炙） 藿香（各一钱） 半夏（热水泡七次，一钱半）
以上用药二钟，生姜三片，大枣二枚，煎至八分，吞服安肾丸。
安肾丸 治疗肾气不足，饭后立即泄泻。另外《金匮翼》说：“喘息因肾虚，吸气不能下达，或者气从小腹下起而上逆，只要稍微劳累，或者饥饿时就会发作，适宜用六味补阴的药物，壮水配火。如果脚冷面热的，必须用安肾类的药物，引导水液回归本源。”
川乌（炮制去皮脐） 辣桂（各四两） 白茯苓（去皮） 白术（土炒） 石斛（酒炒） 白蒺藜（炒） 桃仁（去皮尖，炒） 萆薢 干山药 巴戟天 破故纸（补骨脂） 肉苁蓉（酒浸，各十二两）
以上各药研为细末，用炼蜜制成梧桐子大小的丸剂，每次服用五十丸，淡盐汤送下。
肾气不足，所以用温补类药物来安定它。方中的桃仁、萆薢、蒺藜三味药，不是普通思维可以理解的，方意与八味地黄丸相同。但八味地黄丸长于利水，未免减弱了其温补的力量，而这个方子用药专一且力量更大。
二神丸（方中用肉豆蔻来补脾，破故纸来安肾，所以称为二神） 治疗饭后随即大便。
肉豆蔻（四两，生用） 破故纸（半斤，炒）
以上各药研为细末，用肥大细枣取肉研成膏，与药粉混合捣成丸剂，大小如梧桐子，每次服用五、七十丸，空腹时用米饮加盐送下。加入木香二两，名为三神丸；加入茴香一两，名为四神丸。
Pi Yue Wan (also known as Mahuang Wan)
Houpo (processed with ginger juice), Zhishi (stir-fried with flour), Shaoyao (each 8 liang), Dahuang (steamed and dried, 1 jin), Huomaren (separately ground, 8 liang), Xingren (skin and tip removed, stir-fried, 5.5 liang).
Grind the above herbs into fine powder, mix with refined honey to make pills, size of Sophora japonica seeds. Take 20 pills each time, swallow with warm water before bedtime. Stop when bowel movement becomes smooth.
Note: Standards for weight and measurement differ between ancient and modern times; various schools calculate the proportions of this formula differently, making it impossible to unify them.
San Chengqi Tang (see Shanghan Lun)
Zuo Gui Yin (formula see Headache chapter). This formula adds Shengdi and Danggui to nourish the Yin of the Yangming channel, thereby clearing the dryness-fire of latent pathogens in the stomach and mouth. Fuling is omitted because its action might stray into the Kan (Kidney) region; it is more effective to focus specifically on the Yangming channel for rapid results.
San Yi Chengqi Tang (see Wenyi chapter). Fuzi Lizhong Tang (i.e., Lizhong Tang plus Fuzi).
Zhenwu Tang. Treats vomiting and counterflow qi due to Shaoyin disease, abdominal pain, and short urine, as well as all types of fluid-retention syndromes.
Yunfuling, Baishao, Shengjiang (each 3 qian), Baizhu, Fuzi (each 2 qian).
Decoct in water and take orally.
The brilliance of this formula lies in the pungent-warm nature of Shengjiang to promote Qi circulation; when Qi moves, fluids flow. Contemporary physicians suspect that Shengjiang induces sweating and substitute Ganjiang instead. They fail to realize that Ganjiang is "stationary and does not move," completely losing the original intent of this formula. If further charred or combined with Rougui, it would be even more ignorant and reckless.
Wuzhuyu Tang (see Headache section above). Xiao Chaihu Tang / Da Chaihu Tang. Wu Xiexin Tang (all see Shanghan Lun).
Yueju Wan (created by Zhu Danxi). Treats all types of Yu (depression/stagnation) syndromes.
Xiangfu, Cangzhu, Fuxiong (a type of Chuanxiong), Zhizi, Liushenqu (equal parts). Make into pills or decoction as appropriate.
Dabanxia Tang
Banxia (washed to remove saliva, 6 qian), Renshen (3 qian), Baimi (8 qian).
Add 3.5 cups of water, mix with honey, stir vigorously 240 times, decoct until reduced to 0.8 portion, and take.
The use of a large amount of water in this formula aims to boil the Baimi extensively to remove its cold nature while utilizing its moistening property. This ensures its sticky nature lingers in the stomach rather than descending quickly, allowing the power of Banxia and Renshen to slowly rotate in the middle jiao. Only those who thoroughly understand the principles of creation can comprehend this. The inability of Qi to descend between the throat and diaphragm is caused by the Chong Mai (Penetrating Vessel) ascending and counterflow Qi acting up. When treating disorders of the Chong Mai, one should target the Yangming channel. Zhang Zhongjing used Banxia to subdue the counterflow of the Chong Mai, Baimi to moisten the dryness of the Yangming channel, Renshen to generate lost body fluids, and Ganlan Shui (Ganlan Water) to lower the counterflowing fluid retention. Among the classic formulas of ancient sages, only Zhang Zhongjing could utilize them effectively.
Buhuanjin Zhengqi San. Yang Renzhai stated: "Although Spleen Qi may be strong, if Kidney Qi is insufficient, food and drink will cause loose stools with undigested food in the Large Intestine. Decoct Buhuanjin Zhengqi San and swallow Anshen Wan."
Cangzhu (soaked in rice water), Chenpi (each 2.5 qian), Houpo (processed with ginger juice, 2 qian), Gancao (honey-fried), Huoxiang (each 1 qian), Banxia (soaked in hot water seven times, 1.5 qian).
Use 2 zhong of water, 3 slices of ginger, and 2 dates. Decoct until reduced to 0.8 portion, then swallow Anshen Wan.
Anshen Wan. Treats insufficiency of Kidney Qi causing immediate diarrhea after meals. Additionally, *Jinkui Yi* states: "Asthma due to Kidney deficiency, where inhalation cannot reach down, or Qi rising from the lower abdomen upwards, occurring upon slight exertion or hunger, should be treated with Yin-nourishing formulas like Liuwei Dihuang Wan to strengthen Water to balance Fire. If there are cold feet and a hot face, Anshen-type formulas must be used to guide Water back to its source."
Chuanwu (processed, skin and navel removed), Lagui (each 4 liang), Baifuling (skin removed), Baizhu (earth-stir-fried), Shihu (wine-stir-fried), Baijili (stir-fried), Taoren (skin and tip removed, stir-fried), Bibi, Ganshangyao, Bajitian, Pogu zhi (Buguzhi), Rongrong (wine-soaked, each 12 liang).
Grind all herbs into fine powder, mix with refined honey to make pills size of Sophora japonica seeds. Take 50 pills each time, delivered with light salt water.
Since Kidney Qi is insufficient, warming and tonifying herbs are used to stabilize it. The three herbs Taoren, Bibi, and Jili in this formula are beyond ordinary reasoning. Its conceptual design is similar to Qimuli Huang Wan. However, Qimuli Huang Wan excels at promoting urination, which inevitably reduces its warming and tonifying power, whereas this formula uses specific ingredients with greater potency.
Ershen Wan (uses Roudoukou to tonify Spleen and Pogu zhi to stabilize Kidney, hence named 'Two Divine'). Treats immediate defecation after meals.
Roudoukou (4 liang, raw), Pogu zhi (half jin, stir-fried).
Grind into fine powder. Use flesh from large, thin jujubes, grind into paste, mix with herb powder, and pound into pills size of Sophora japonica seeds. Take 50-70 pills each time, delivered with rice drink and salt on an empty stomach. Add Muxiang (2 liang) to name Sanshen Wan; add Huixiang (1 liang) to name Sishen Wan.
