阳毒升麻汤
升麻（半两） 当归 蜀椒 雄黄 桂枝（各一两） 每服五钱。
水一钟半。煎一盏温服。复手足取汗。得吐亦佳。
阴毒甘草汤
甘草 升麻（各半两） 当归 川椒 鳖甲（各一两） 每服五钱。水一盏半。煎一盏服。
此二方。与伤寒论阳毒阴毒特异。故记之。是感天地疫疠非常之气。沿家传染。所谓时疫证者是也。

何也。答曰。诸紧为寒。火亏也。为内虚水少。为木胜金弱。故服之亦效。
阳毒升麻汤
升麻（半两） 当归 蜀椒 雄黄 桂枝（各一两） 每次服用五钱。
用水一钟半，煎煮至一盏，温服。服药后覆盖手足以取汗。能呕吐出来也很好。
阴毒甘草汤
甘草 升麻（各半两） 当归 川椒 鳖甲（各一两） 每次服用五钱。用水一盏半，煎煮至一盏服用。
这两个方子，与《伤寒论》中治疗阳毒和阴毒的方剂不同。所以记录下来。这是感受了天地间异常的疫疠之气，导致全家传染，所说的时疫证就是这类病。
古方逍遥散
柴胡 薄荷 当归 芍药 陈皮 甘草 白术 茯神 加味者，加牡丹皮、山栀。我用山栀因其屈曲下行以泄水，改用茱萸炒黄连。
麻黄桂枝汤
人参（补益上焦元气不足而充实体表） 麦门冬（保护肺气各三分） 桂枝（辛甘发散寒气） 当归（调和血液、养血各五分） 麻黄（去根沫，主要发散寒气） 甘草（味甘发散寒气） 黄芪（充实体表、增益卫气） 白芍药（以上各一钱） 五味子（五个，安定脉气） 以上药物用三盏水，先单独煮麻黄一味，煮沸后去掉浮沫，水量减至二盏，再加入其余药物同煎至一盏，去渣热服。只需服用一次即可痊愈，不再发作。
八味丸 治疗命门火衰，不能生助脾土，导致脾胃虚寒，饮食减少思虑，大便不成形，或者下元衰惫，脐腹疼痛，夜间多尿等症状。
熟地黄（八两，用真生怀庆酒洗净浸泡一夜，在柳木蒸笼、砂锅上蒸半天，晒干，再蒸再晒，共九次为度，临用时捣成膏） 山药（四两） 山茱萸肉（四两） 丹皮（三两） 白茯苓（三两） 泽泻（三两） 肉桂（一两） 附子（一两）
制附子法：附子重一两三四钱，有莲花瓣形状，头圆底平的为佳。准备童便五六碗，浸泡五七日，候其透润，剥去外皮切成四块，仍浸泡三四日，用粗纸数层包裹，浸入湿灰火中煨烤，取出切片，查看有白色星点者，仍用新瓦片上炙热，直到没有星点为止。如果急于使用，就切大片，用童便煮三四沸，在新瓦片上炮熟使用。
八味丸，是张仲景所创制的方剂。《圣惠方》说，它能伐除肾邪，都是君主之药，适宜加减使用。加减如果不依据易老（李东垣）的方法也不见效。现在有人加入人参的，人参是脾经药，到不了肾经；有人加入黄柏、知母的，有人想减少泽泻的，都不了解立方的本意。
六味丸加五味子名为都气丸，这是取“述类象形”的意思。
钱乙减去桂附，名为六味地黄丸，用来治疗小儿，因为小儿纯阳，所以减去桂附。
杨氏说，常服用去掉附子加五味子，名为加减八味丸。
丹溪有三一肾气丸，唯独这个方子不可用。
仲景有金匮肾气丸。
益阴地黄丸，治疗目病火衰者；济阴地黄丸，治疗目病有火者。两个方子见《原机启微》。
易老说，八味丸治疗脉耗而虚，是西北两地的药剂。金弱木胜，水少火亏，或者脉象鼓动按之有力，服用它也有效。为什么呢？回答说，诸紧脉为寒，火亏也，为内虚水少，为木胜金弱，所以服用它也有效。
Yang Du Shengma Decoction (Corydalis Rhizoma and Cinnamon Twig Decoction for Yang Toxin)
Shengma (Rhizoma Cimicifugae, half tael), Danggui (Radix Angelicae Sinensis), Shujiao (Fructus Zanthoxyli), Xionghuang (Realgar), Guizhi (Ramulus Cinnamomi, each one tael). Take five qian per dose.
Use one and a half zhong of water, decoct to obtain one zhong, take warm. Cover hands and feet to induce sweating. Vomiting is also beneficial.
Yin Du Gancao Decoction (Licorice Decoction for Yin Toxin)
Gancao (Radix Glycyrrhizae), Shengma (Rhizoma Cimicifugae, each half tael), Danggui (Radix Angelicae Sinensis), Chuanjiao (Fructus Zanthoxyli), Biejia (Carapax et Plastrum Testudinis, each one tael). Take five qian per dose. Use one zhong and a half of water, decoct to obtain one zhong, take.
These two formulas are distinct from those for Yang Toxin and Yin Toxin in the Shanghan Lun (Treatise on Cold Damage). Therefore, they are recorded here. This refers to contracting the abnormal qi of epidemic pestilence from heaven and earth, which spreads contagiously within families. This is what is referred to as "Shiyi Zheng" (Seasonal Epidemic Syndrome).
Ancient Formula Xiaoyao San (Free and Easy Wanderer Powder)
Chaihu (Radix Bupleuri), Bohe (Herba Menthae), Danggui (Radix Angelicae Sinensis), Shaoyao (Radix Paeoniae Alba), Chenpi (Pericarpium Citri Reticulatae), Gancao (Radix Glycyrrhizae), Baizhu (Rhizoma Atractylodis Macrocephalae), Fushen (Sclerotium Poria cum Radix Pini). For modified versions, add Danpi (Cortex Moutan) and Shanzhi (Fructus Gardeniae). I use Shanzhi because it descends curving downwards to drain dampness; instead, I use Zhuyu (Fructus Corni) stir-fried with Huanglian (Rhizoma Coptidis).
Mahuang Guizhi Tang (Ephedra and Cinnamon Twig Decoction)
Renshen (Radix Ginseng, to tonify deficiency of Yuan Qi in the Upper Jiao and solidify the exterior), Maimendong (Radix Ophiopogonis, each three fen to protect Lung Qi), Guizhi (Ramulus Cinnamomi, acrid and sweet to disperse cold pathogenic factors), Danggui (Radix Angelicae Sinensis, each five fen to harmonize and nourish blood), Mahuang (Herba Ephedrae, root tips and foam removed, primarily to disperse cold pathogenic factors), Gancao (Radix Glycyrrhizae, sweet in flavor to disperse cold pathogenic factors), Huangqi (Radix Astragali, to solidify the exterior and benefit Wei Qi), Baishaoyao (Radix Paeoniae Alba, each one qian above), Wuweizi (Fructus Schisandrae, five fruits to calm the pulse qi). Use three zhan of water. First decoct Mahuang alone until boiling, remove the foam. Reduce to two zhan. Add remaining herbs and decoct together to obtain one zhan. Remove dregs and take hot. One dose is sufficient for cure, and it will not recur.
Bawei Wan (Eight-Ingredient Pill with Rehmannia)
Treats Mingmen Fire Decline (Decline of Vital Gate Fire), inability to generate Earth (Spleen/Stomach), resulting in Spleen-Stomach Deficiency-Cold, lack of appetite, loose stools, or decline of the Lower Origin, pain in the umbilical and abdominal regions, frequent urination at night, etc.
Shudihuang (Prepared Radix Rehmanniae, eight taels, washed clean with genuine raw Huaiqing wine, soaked overnight, steamed for half a day in a willow wood steamer over a clay pot, sun-dried, then steamed and dried again, repeated nine times as the standard. Before use, pound into paste), Shanyao (Rhizoma Dioscoreae, four taels), Shanzhuyu (Fructus Corni, four taels), Danpi (Cortex Moutan, three taels), BaiFuling (Poria, three taels), Zexie (Rhizoma Alismatis, three taels), Rougui (Cortex Cinnamomi, one tael), Fuzi (Radix Aconiti Lateralis Preparata, one tael).
Method for processing Fuzi: Select Fuzi weighing one tael and three or four qian, with lotus petal patterns, round head and flat base being best. Prepare five or six bowls of Tongbian (Child's Urine). Soak for five to seven days until thoroughly moistened. Peel off the skin and cut into four pieces. Continue soaking for three to four days. Wrap in several layers of coarse paper, soak wet, and roast in embers. Take out, slice, and check for white spots. If present, heat again on a new tile until no spots remain. If urgent, cut into large slices, boil in Tongbian for three or four boils, and roast熟 on a hot tile.
Bawei Wan was formulated by Zhang Zhongjing. The Shenghui Fang states that it can subdue Kidney pathogens and serves as a sovereign drug. It should be used with modifications. Modifications not based on Li Dongyuan's principles are ineffective. Some people today add Renshen, but Renshen is a Spleen Meridian herb and does not reach the Kidney Meridian. Some add Huangbai (Cortex Phellodendri) and Zhimu (Rhizoma Anemarrhenae); some wish to reduce Zexie. All these fail to understand the original intent of the formula.
Liuwei Wan (Six-Ingredient Pill with Rehmannia) plus Wuweizi is called Duqi Wan, reflecting the meaning of "describing categories and resembling forms."
Qian Yi reduced Guizhi and Fuzi, naming it Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia), used for children because children are purely Yang, hence Guizhi and Fuzi are reduced.
Yang Shi stated that for regular consumption, remove Fuzi and add Wuweizi, named Jiabian Bawei Wan (Modified Eight-Ingredient Pill).
Danxi has Sanyi Shenqi Wan, but this specific formula should not be used.
Zhongjing has Jingui Shenqi Wan (Kidney Qi Pill from the Golden Cabinet).
Yiyin Dihuang Wan treats eye diseases caused by Fire Decline; Jiyin Dihuang Wan treats eye diseases with Fire. Both formulas are found in Yuanji Qiuwei.
Li Dongyuan said that Bawei Wan treats a pulse that is exhausted and deficient; it is a remedy for the Northwest regions. When Metal is weak and Wood prevails, Water is scarce and Fire is deficient, or when the pulse is bounding and forceful upon pressure, taking it is also effective. Why? The answer is: all tight pulses indicate Cold, which implies Fire Deficiency, internal deficiency with scant Water, and Wood prevailing over weak Metal. Therefore, taking it is also effective.
