治疗脾肺两脏俱虚，出现发热、恶寒，肢体消瘦疲倦，饮食减少且大便泄泻等症状。如果是气血虚弱导致的变化多端的各种症状，不论其具体病名和脉象如何，使用以下方剂：人参、白术、茯苓、甘草、黄芪、陈皮、当归、熟地黄、白芍、五味子、肉桂心、远志。以上十二味药，加生姜三片、大枣二枚，加水煎煮后服用。
柯韵伯说：古人治疗气虚用四君子汤，治疗血虚用四物汤，气血两虚的用八珍汤，再加上黄芪、肉桂，名为十全大补汤。如果用于治疗思虑过度损伤脾胃，或者出现健忘、心慌心跳、惊悸、盗汗、醒着却睡不着（寤而不寐）；或者心脾部位疼痛、嗜睡、食欲减退、月经不调等症状，使用归脾汤：人参、黄芪、甘草、白术、茯苓、木香、龙眼肉、酸枣仁、当归、远志。加生姜三片，加水煎煮后服用。
罗东逸说：方中的龙眼肉、酸枣仁、当归，是用来补心的；人参、黄芪、白术、茯苓、甘草，是用来补脾的。
张路玉说：补中益气汤与归脾汤，都源于保元汤的基础，并加入了当归、白术，但前者侧重于升提胃气，后者侧重于滋补脾阴。对于饮食减少的患者，是因为方中纯阴无阳，不能运化药力所致！
这是治疗气虚血弱的总括方剂。小儿患惊风或痘疹属虚证的，最适合使用。黄芪（三钱）、人参（二钱）、甘草（一钱）、肉桂（春夏季二三分，秋冬季六七分）。以上四味药，加水煎煮后服用。
柯韵伯说：所谓“保元”，就是保守人体元气的意思。气只有一种，它主宰肾脏，是先天真元之气；它主宰胃腑，是后天之气。……（原文此处有缺漏，根据语境推测涉及先后天关系及脏腑协调）。如适宜燥湿则加茯苓、白术，适宜滋润加当归，适宜收敛加白芍，应当发散加川芎。又有表实证去掉黄芪，里实证去掉人参，中焦胀满忌用甘味药，内有热象去除肉桂，这些又应当仔细领会。（推演阐明加减法，条理清晰。）
又说：人们知道火能克金，却不知道气能胜火；人们知道金能生水，却不知道气即是水。这一深意只有李东垣知道……（原文此处截断，推测为李东垣对气与水关系的论述）。
Treats conditions of simultaneous deficiency of the Spleen and Lung, manifesting as fever, aversion to cold, emaciation and fatigue of the limbs, decreased appetite, and diarrhea. If various symptoms arise due to Qi and Blood deficiency, regardless of the specific disease name or pulse presentation, use the following prescription: Renshen (Ginseng Radix), Baizhu (Atractylodis Macrocephalae Rhizoma), Fuling (Poria), Gancao (Licorice Root), Huangqi (Astragali Radix), Chenpi (Citri Reticulatae Pericarpium), Danggui (Angelicae Sinensis Radix), Shudi (Rehmanniae Radix Preparata), Baishao (Paeoniae Radix Alba), Wuweizi (Schisandrae Chinensis Fructus), Guixin (Cinnamomi Cortex), Yuanzhi (Polygalae Radix). The above twelve herbs, with three slices of fresh ginger and two dates, decocted in water and taken orally.
Ke Yunbo stated: In ancient times, Si Jun Zi Tang (Four Gentlemen Decoction) was used for Qi deficiency, Si Wu Tang (Four Substance Decoction) for Blood deficiency, and Ba Zhen Tang (Eight Treasures Decoction) for both Qi and Blood deficiency. Adding Huangqi (Astragali Radix) and Rougui (Cinnamon Bark) creates Shi Quan Da Bu Tang (Ten Complete Great Tonifying Decoction). For treating thoughtfulness overtaxing the Spleen, or symptoms such as forgetfulness, palpitations,惊悸 (startle palpitations), night sweats, insomnia while awake; or pain in the Heart and Spleen regions, lethargy, poor appetite, and irregular menstruation, use Gui Pi Tang (Restore the Spleen Decoction): Renshen (Ginseng Radix), Huangqi (Astragali Radix), Gancao (Licorice Root), Baizhu (Atractylodis Macrocephalae Rhizoma), Fuling (Poria), Muxiang (Aucklandiae Radix), Longyanrou (Longan Aril), Suanzaoren (Ziziphi Spinosae Semen), Danggui (Angelicae Sinensis Radix), Yuanzhi (Polygalae Radix). Add three slices of fresh ginger, decoct in water, and take orally.
Luo Dongyi stated: In this formula, Longyanrou (Longan Aril), Suanzaoren (Ziziphi Spinosae Semen), and Danggui (Angelicae Sinensis Radix) are used to tonify the Heart; Renshen (Ginseng Radix), Huangqi (Astragali Radix), Baizhu (Atractylodis Macrocephalae Rhizoma), Fuling (Poria), and Gancao (Licorice Root) are used to tonify the Spleen.
Zhang Luyu stated: Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction) and Gui Pi Tang (Restore the Spleen Decoction) both originate from the basis of Bao Yuan Tang (Preserve the Origin Decoction), adding Danggui (Angelicae Sinensis Radix) and Baizhu (Atractylodis Macrocephalae Rhizoma). However, the former focuses on raising Stomach Qi, while the latter focuses on nourishing Spleen Yin. For patients with decreased food intake, it is because the formula is purely Yin without Yang, failing to transform and transport the medicinal power!
This is the general formula for treating Qi deficiency and Blood weakness. It is most suitable for children with deficiency patterns in Jing Feng (Startle Wind) or Dou Zhen (Smallpox/Chickenpox). Huangqi (Astragali Radix) (3 qian), Renshen (Ginseng Radix) (2 qian), Gancao (Licorice Root) (1 qian), Rougui (Cinnamon Bark) (2-3 fen in Spring/Summer, 6-7 fen in Autumn/Winter). The above four herbs, decocted in water and taken orally.
Ke Yunbo stated: "Bao Yuan" means preserving the original Qi. Qi is singular; it governs the Kidney as the congenital true Yuan Qi; it governs the Stomach as the acquired Qi... [Text fragment]. As appropriate for dryness, add Fuling (Poria) and Baizhu (Atractylodis Macrocephalae Rhizoma); for moistening, add Danggui (Angelicae Sinensis Radix); for astringing, add Baishao (Paeoniae Radix Alba); for dispersing, add Chuanxiong (Ligustici Chuanxiong Rhizoma). Furthermore, if there is exterior excess, remove Huangqi (Astragali Radix); if interior excess, remove Renshen (Ginseng Radix); if middle jiao fullness, avoid sweet herbs; if internal heat, remove Rougui (Cinnamon Bark). These points require careful understanding. (The deduction of modifications is clear.)
He also said: People know that Fire can overcome Metal, but do not know that Qi can overcome Fire; people know that Metal can generate Water, but do not know that Qi is essentially Water. This profound meaning was known only by Li Dongyuan... [Text cuts off].
