治胃气虚弱。饮食不思。倦怠少食。
人参（一钱至三钱） 白术（炒黄。一钱至二钱。） 茯苓（一钱至钱半。） 甘草（炙。六分至一钱。）
上四味。水煎。空心温服。按四君子乃胃家气分之专药。胃气虚而用之。功效立见。即血虚用四物。
亦必兼此。故八珍之主治。不独气血两虚也。即血虚者亦须兼用。但补气则偏于四君。补血则偏于
四物。若纯用血药。不得阳生之力。阴无由以化也。方中白术。若治脾胃虚衰。大便不实。或呕恶不食。
合用炒焦。方有健运之力。如肺胃虚燥。咳嗽失血。须用陈米饭上蒸过十余次者。则转浊为清。
转燥为润。是以异功散、八珍汤及归脾、逍遥等方内。并宜蒸者。即阴虚干咳。咳吐白血。总无妨碍。
更加白蜜拌蒸。犹为合宜。其于轻重炮制之间。全在用者之活法权变。举
此可以类推三隅矣。

四君子汤去茯苓。加肉桂、附子、黄 、牛膝、杜仲、熟地、白芍、川芎、羌活、防风。
治疗胃气虚弱。饮食没有食欲。疲倦乏力、进食减少。
人参（一钱至三钱） 白术（炒至黄色。一钱至二钱。） 茯苓（一钱至一两半。） 甘草（炙。六分至一钱。）
以上四味药。加水煎煮。空腹时温服。按语：四君子汤是调理脾胃气分的专用药物。胃气虚弱时使用它，功效立刻显现。即使是血虚证使用四物汤（四物汤），也必须兼用此方。所以八珍汤（八珍汤）的主治范围，不仅仅是气血两虚证。即便是血虚证，也应当兼用补气药。但补气则侧重于四君子汤，补血则侧重于四物汤。如果纯用补血药，得不到阳气生长的力量，阴血就无法化生。方中的白术，如果是治疗脾胃虚衰导致的大便不成形，或者呕吐恶心不想吃东西，应当合用炒焦的白术，这样才有健运脾胃的功效。如果是肺胃阴虚燥热，咳嗽咯血，必须使用在陈米饭上蒸过十多次的白术，这样才能将浊气转为清气，将燥性转为润性。因此异功散（异功散）、八珍汤以及归脾汤（归脾汤）、逍遥散（逍遥散）等方剂中，都适宜使用蒸制的白术。即使是阴虚干咳，咳吐白色泡沫痰，也没有妨碍。再加白蜜拌蒸，更为合适。至于炮制轻重的变化，全在于医者灵活运用、随机应变。举这个例子可以类推其他情况了。

九味资生丸 治疗老人食物难以消化运化。
四君子汤本方人参、白术各三两。茯苓一两半。炙甘草半两。加橘红、山楂肉、真神曲各二两。川黄连、白豆蔻各三钱半、炼白蜜制成丸剂服用。古方只有这九味药。后人又加了桔梗、藿香各半两。泽泻三钱半。扁豆、莲肉各一两。薏苡仁三两。山药、麦芽、芡实各一两半。酒醉饱食后细细咀嚼弹子大一丸。淡姜汤送下。那么酒食容易消化。健脾开胃。消食止泻。调和脏腑。滋养营卫。饥饿时服用就会觉得饱。饱食后服用就会觉得饿。药物虽然繁简不同。而功效没有差异。因此两种方子都保留下来。
八物汤 治疗营卫俱虚。畏寒发热。
八珍汤去掉人参加入黄芪。按语：八珍汤、八物汤功用相差悬殊。因为人参专门补益脏腑元气。黄芪只主管营卫的开阖。世人常常说黄芪代替人参。经常用八物汤补益脏腑之气。实在令人喷饭。
人参胃风汤（局方） 治疗风邪入胃中。能进食但便血。
四君子汤去掉甘草加当归、白芍、川芎、桂枝、粟米。另一版本。多木香。按语：风邪入胃中。为什么反而能进食？大概风为阳邪。其性质善于行走。久而化热。就是内经所说的瘅成为消中症的情况。方中只用桂枝祛风。而不清热的原因。是因为热邪必定随风邪从体表解除。不必另外治疗罢了。
益气养营汤 治疗瘰疬结核流注。一切郁热毒瓦斯。
八珍汤加黄芪、桔梗、贝母、香附、橘皮、生姜。
大防风汤（局方） 治疗邪气侵袭足三阴经。腿膝疼痛。以及痢疾后胫膝痛。鹤膝风。附骨疽证。但是赤热肿者禁用。
四君子汤去掉茯苓。加肉桂、附子、黄芪、牛膝、杜仲、熟地、白芍、川芎、羌活、防风。
Treats Stomach Qi deficiency (Stomach Qi deficiency). Lack of appetite for food. Fatigue and reduced food intake.
Ren Shen (Ginseng Radix) (1 qian to 3 qian), Bai Zhu (Atractylodis Rhizoma) (stir-fried until yellow, 1 qian to 2 qian), Fu Ling (Poria) (1 qian to 1.5 liang), Gan Cao (Licorice Root) (honey-fried, 6 fen to 1 qian).
The above four ingredients. Decoct in water. Take warm on an empty stomach. Note: Si Jun Zi Tang (Four Gentlemen Decoction) is the specific medicine for regulating the Qi aspect of the Stomach. When used for Stomach Qi deficiency, its efficacy is seen immediately. Even when using Si Wu Tang (Four Substances Decoction) for Blood deficiency, it is necessary to combine this formula. Therefore, the indications for Ba Zhen Tang (Eight Treasures Decoction) are not limited to dual deficiency of Qi and Blood. Even in cases of Blood deficiency, Qi-tonifying herbs should be combined. However, tonifying Qi focuses on Si Jun Zi Tang, while nourishing Blood focuses on Si Wu Tang. If purely using Blood-nourishing herbs, without the power of Yang generation, Yin cannot be transformed. In the formula, if Bai Zhu is used to treat Spleen-Stomach deficiency leading to loose stools, or vomiting, nausea, and anorexia, stir-fried charred Bai Zhu should be combined, so that it possesses the power of strengthening and transporting. For Lung-Stomach deficiency with dryness, coughing, and hemoptysis, Bai Zhu steamed over aged rice more than ten times must be used, thereby transforming turbidity into clarity and dryness into moistness. Therefore, in Yi Gong San (Extraordinary Efficacy Powder), Ba Zhen Tang, Gui Pi Tang (Restore the Spleen Decoction), Xiao Yao San (Free Wanderer Powder), and other formulas, steamed Bai Zhu is appropriate. Even for Yin deficiency with dry cough and expectoration of white frothy sputum, there is no hindrance. Adding White Honey (Apis mellifera honey) for拌蒸 (steaming with mixing) is even more suitable. Regarding the variations in light and heavy processing, it entirely depends on the practitioner's flexible application and adaptive changes. Taking this as an example, one can infer other situations.
Yi Gong San Treats Lung-Stomach Qi deficiency. Thin phlegm, wheezing, and cough.
Si Jun Zi Tang plus Chen Pi (Citri Reticulatae Pericarpium) (white pith removed slightly). Pulverized into powder. Take 3-4 qian per dose. Add one slice of Sheng Jiang (Zingiberis Rhizoma Recens). Decoct in water. Strain and take.
Liu Jun Zi Tang Treats Stomach deficiency with poor appetite. Phlegm-cough, vomiting, and diarrhea.

Xing Xing San (Ju Fang) Treats pediatric Shang Han (Cold Damage). Fever and cough.
Si Jun Zi Tang plus Jie Geng, Xi Xin (Asari Radix et Rhizoma), Qiang Huo (Notopterygii Rhizoma et Radix). (Another version uses Hua Fen [Trichosanthis Radix]). Equal parts pulverized into powder. Take 1-2 qian per dose. Add five leaves of Bo He (Menthae Haplocalycis Herba). Decoct in water and take hot. Induce slight sweating for cure. If not cured, administer again. Add Cong Bai (Allii Fistulosi Bulbus) and Xiang Chi (Sojae Semen Praeparatum).
Si Shou Yin Treats Malaria with Stomach deficiency, complicated by Phlegm and Food retention.
Si Jun Zi Tang plus Ban Xia, Chen Pi, Cao Guo (Tsaoko Fructus) pulverized into powder. Take 4-5 qian per dose. Add seven slices of Sheng Jiang. One piece of Wu Mei Rou. Decoct in water. Take hot early in the morning.
Ba Wei Shun Qi San Treats Lei Zhong Feng (Stroke-like syndrome) with empty distension and wheezing/reversal of Qi.
Si Jun Zi Tang plus Qing Pi (Citri Reticulatae Pericarpium Viride), Chen Pi, Bai Zhi (Angelicae Dahuricae Radix), Wu Yao (Linderae Radix) pulverized into powder. Take 4-5 qian per dose. Decoct in water. Take warm.
Shen Ling Bai Zhu San (Ju Fang. Also known as Shen Zhu Yin.) Treats Stomach deficiency with wheezing/cough and loose stools.
Si Jun Zi Tang plus Shan Yao (Dioscoreae Rhizoma), Bian Dou (Vignae Semen), Lian Rou (Nelumbinis Plumula), Jie Geng, Yi Yi Ren (Coicis Semen), Sha Ren. Pulverized into powder. Take 4-5 qian per dose. Add Jiang and Zao and decoct.
Qi Wei Bai Zhu San (i.e., Qian Shi Bai Zhu San.) Treats Stomach deficiency with failure of Jin-Yi (Body Fluids and Qi) to circulate, leading to thirst.
Si Jun Zi Tang plus Huo Xiang, Mu Xiang, Wei Ge Gen (Prepared Puerariae Radix) pulverized into powder. Take 3-4 qian per dose. Decoct in water. Take three times daily.
Ba Zhen San Treats Stomach deficiency with blood in phlegm. And pink-colored sputum.
Si Jun Zi Tang plus Huang Qi, Shan Yao, Su Mi (Panicum miliaceum), Bian Dou. (Stir-fried until carbonized but retaining nature).
Jiu Wei Zi Sheng Wan Treats elderly people with difficulty digesting and transporting food.
The base formula of Si Jun Zi Tang: Ren Shen and Bai Zhu each 3 liang. Fu Ling 1.5 liang. Zhi Gan Cao 0.5 liang. Plus Ju Hong (Citri Reticulatae Pericarpium Rubrum), Zha Rou (Crataegi Fructus), Zhen Shen Qu each 2 liang. Chuan Huang Lian (Coptidis Rhizoma), Bai Dou Kou (Cardamomi Fructus) each 3.5 qian. Form pills with refined White Honey. Ancient formulas contained only these nine ingredients. Later generations added Jie Geng and Huo Xiang each 0.5 liang. Ze Xie (Alismatis Rhizoma) 3.5 qian. Bian Dou and Lian Rou each 1 liang. Yi Yi Ren 3 liang. Shan Yao, Mai Ya (Hordei Fructus Germinatus), Qian Shi (Euryales Semen) each 1.5 liang. After drinking or overeating, chew finely one pill the size of a marble. Descend with light Ginger Soup. Then alcohol and food are easily digested. Strengthens Spleen and opens appetite. Eliminates food stagnation and stops diarrhea. Harmonizes Zang-Fu organs. Nourishes Ying and Wei. Taken when hungry, one feels full. Taken after eating, one feels hungry. Although the complexity of the prescription differs, the efficacy is identical. Therefore, both are preserved.
Ba Zhen Tang Treats women with Tai Chan Beng Lou (gestational/postpartum metrorrhagia). Cases of dual deficiency of Qi and Blood.
Si Jun Zi Tang combined with Si Wu Tang.
Ba Wu Tang Treats dual deficiency of Ying and Wei. Aversion to cold and fever.
Ba Zhen Tang minus Ren Shen plus Huang Qi. Note: The functions of Ba Zhen Tang and Ba Wu Tang differ significantly. Because Ren Shen specifically tonifies the Yuan Qi of Zang-Fu organs, whereas Huang Qi only governs the opening and closing of Ying and Wei. People often say Huang Qi can replace Ren Shen, and frequently use Ba Wu Tang to tonify the Qi of Zang-Fu organs. This is truly laughable.
Ren Shen Wei Feng Tang (Ju Fang) Treats Wind pathogen entering the Stomach. Ability to eat but with bloody stools.
Si Jun Zi Tang minus Gan Cao plus Dang Gui (Angelicae Sinensis Radix), Bai Shao (Paeoniae Radix Alba), Chuan Xiong (Chuanxiong Rhizoma), Gui Zhi (Cinnamomi Ramulus), Su Mi. Another version adds Mu Xiang. Note: Why does Wind entering the Stomach allow for eating? Generally, Wind is a Yang pathogen. Its nature is good at moving. Over time it transforms into Heat. This is what the Nei Jing refers to as Dan becoming Xiao Zhong (Gluttony disease). The formula uses only Gui Zhi to dispel Wind, without clearing Heat, because Heat will necessarily resolve externally along with the Wind, requiring no separate treatment.
Yi Qi Yang Ying Tang Treats Luo Li (scrofula) nodules, Liu Zhu (flowing abscesses). All kinds of stagnant Heat and toxic vapors.
Ba Zhen Tang plus Huang Qi, Jie Geng, Bei Mu (Fritillariae Bulbus), Xiang Fu (Cyperi Rhizoma), Chen Pi, Sheng Jiang.
Da Fang Feng Tang (Ju Fang) Treats pathogenic invasion of the Foot Three Yin meridians. Pain in legs and knees. And pain in shins and knees after dysentery. He Xi Feng (Crane Knee Wind). Fu Gu Ju (Bone-attached abscess). Contraindicated in cases with redness, heat, and swelling.
Si Jun Zi Tang minus Fu Ling. Plus Rou Gui (Cinnamomi Cortex), Fu Zi (Aconiti Lateralis Radix Preparata), Huang Qi, Niu Xi (Achyranthis Bidentatae Radix), Du Zhong (Eucommiae Cortex), Shu Di (Rehmanniae Radix Preparata), Bai Shao, Chuan Xiong, Qiang Huo, Fang Feng (Saposhnikoviae Radix).
