人有元阳，命曰真火，此火一衰则不能生土，而资生之本大虚，今以附子回少火，干姜暖中州，
而参，术、甘草为火补气，气旺则火足而脾土自能健运。《经》曰∶气主煦之。又曰∶寒淫所胜，
平以辛热。即补火之谓也。夫心上肾下肝左肺右，而脾独居中，中气空虚，四脏不能相生，得此方
以理之，则万物之母安而四脏皆得禀矣，故曰理中汤。去参术即名四逆汤，为四肢厥逆者设也。

陈年黄米（半斤）、莲子肉（半斤）、花椒（二两，炒后研磨），每天早晨空腹时，用黑砂糖调和姜汤送服，用量不限。
治疗脾胃虚弱，不想进食，或者呕吐，或者腹泻。人参、茯苓、白术（土炒）、甘草（炙烤）、山药（炒制）、白扁豆（炒制，各四两）、砂仁（炒制）、桔梗（炒制）、薏苡仁（炒制）、莲子肉（炒制，去芯，各二两），共研为细末，用生姜和大枣煎汤调服。
脾胃属土，土是万物的母亲，李东垣说：脾胃虚弱则百病丛生，调理中焦脾胃，是第一要务。脾喜欢甘味，所以用人参、甘草、薏苡仁；不喜欢燥湿，所以用白术、茯苓；脾喜欢香气，所以用砂仁；火生土（心为脾之母），所以用莲子肉补益心脏；土克制水（肾属水），所以用山药治疗肾脏疾病；桔梗入肺经，能升能降，从而通达天气，在地道（脾胃）中没有痞塞的忧虑。
治疗脾胃虚寒，饮食不消化，或者手脚冰凉，胸腹剧烈疼痛，或者痰气不畅，口舌生疮，或者呕吐泄泻等症状。去掉附子就叫做人参理中汤。人参（去芦头，一两）、白术（土炒，二两）、干姜（炮制，一两）、甘草（炙烤，二两）、附子（炮制成熟，一枚），每次服用八钱，用水煎服。
人有元阳，称为真火，这火一旦衰弱就不能生养脾土，而资生的根本大大虚弱，现在用附子回复少火（命门之火），干姜温暖中焦脾胃，而人参、白术、甘草补气，气旺盛则火充足，脾土自然能够健运。《内经》说：气主要起温煦作用。又说：寒邪盛行，用辛热之药来平抑。这就是补火的意思。心在上，肾在下，肝在左，肺在右，唯独脾居中，中气空虚，四脏不能相生，得到这个方子来调理它，那么万物之母（脾）安定，四脏都能禀受滋养，所以叫理中汤。去掉人参和白术就叫做四逆汤，是为四肢厥逆的患者设立的。
Bai Zhu (Atractylodis Macrocephalae Rhizoma), Fu Ling (Poria), Gan Jiang (Zingiberis Rhizoma Preparatum), Huang Lian (Coptidis Rhizoma Prepared with Wine), Mu Xiang (Aucklandiae Radix), Rou Dou Kou (Myristicae Semen Prepared in Flour Paste), each one qian, ground into fine powder, made into pills with wheat paste, taken with a decoction of Centella Asiatica herb and glutinous rice.
Tu Si Zi (Cuscutae Semen) (one jin), Gan Jiang (Zingiberis Rhizoma) (half a jin), Da Zao (Jujubae Fructus) (one jin), pounded and made into pills, taken with rice soup every morning, three qian per dose.
Chen Huang Mi (Setaria Italica Grain) (half a jin), Lian Rou (Nelumbinis Plumula) (half a jin), Hua Jiao (Zanthoxyli Pericarpium) (two liang, stir-fried and ground), taken every morning on an empty stomach, mixed with black sugar and ginger soup, dosage unrestricted.
Treats Spleen and Stomach deficiency and weakness, loss of appetite, or vomiting, or diarrhea. Ren Shen (Ginseng Radix), Fu Ling (Poria), Bai Zhu (Atractylodis Macrocephalae Rhizoma Stir-fried with Soil), Gan Cao (Licorice Root Preparatum), Shan Yao (Dioscoreae Rhizoma Stir-fried), Bai Bian Dou (Lablab Seed Stir-fried), each four liang; Sha Ren (Amomi Fructus Stir-fried), Jie Geng (Platycodonis Radix Stir-fried), Yi Yi Ren (Coicis Semen Stir-fried), Lian Rou (Nelumbinis Plumula Stir-fried, core removed), each two liang. Ground into fine powder, taken with a decoction of Sheng Jiang (Zingiberis Rhizoma) and Da Zao (Jujubae Fructus).
The Spleen and Stomach belong to Earth, and Earth is the mother of all things. Li Dongyuan said: "When the Spleen and Stomach are deficient, hundreds of diseases arise." Regulating the Middle Jiao is the primary task. The Spleen delights in sweetness, hence Ren Shen (Ginseng Radix), Gan Cao (Licorice Root Preparatum), and Yi Yi Ren (Coicis Semen) are used; it dislikes dryness, hence Bai Zhu (Atractylodis Macrocephalae Rhizoma) and Fu Ling (Poria) are used; the Spleen delights in fragrance, hence Sha Ren (Amomi Fructus) is used; Fire generates Earth (Heart is the mother of Spleen), hence Lian Rou (Nelumbinis Plumula) is used to benefit the Heart; Earth controls Water (Kidney belongs to Water), hence Shan Yao (Dioscoreae Rhizoma) is used to treat the Kidney; Jie Geng (Platycodonis Radix) enters the Lung meridian, capable of ascending and descending, thereby connecting with Heaven Qi, preventing stagnation in the Di Dao (Spleen/Stomach).
Treats Spleen and Stomach deficiency-cold, indigestion, cold limbs, severe chest and abdominal pain, phlegm-qi obstruction, mouth and tongue sores, vomiting, or diarrhea. Removing Fu Zi (Aconiti Lateralis Radix Preparata) makes it Ren Shen Lizhong Tang (Ginseng Decoction for Regulating the Middle). Ren Shen (Ginseng Radix, rhizome removed, one liang), Bai Zhu (Atractylodis Macrocephalae Rhizoma Stir-fried with Soil, two liang), Gan Jiang (Zingiberis Rhizoma Preparatum, one liang), Gan Cao (Licorice Root Preparatum, two liang), Fu Zi (Aconiti Lateralis Radix Preparata, thoroughly processed, one piece). Each dose is eight qian, decocted in water and taken orally.
Humans possess Yuan Yang, called True Fire. If this fire declines, it cannot generate Earth (Spleen), causing the root of nourishment to be severely deficient. Now, using Fu Zi (Aconiti Lateralis Radix Preparata) to restore the Minor Fire (Mingmen Fire), Gan Jiang (Zingiberis Rhizoma Preparatum) to warm the Middle Jiao, while Ren Shen (Ginseng Radix), Bai Zhu (Atractylodis Macrocephalae Rhizoma), and Gan Cao (Licorice Root Preparatum) tonify Qi. When Qi is abundant, Fire is sufficient, and the Spleen and Earth can naturally function vigorously. The Classic states: "Qi primarily provides warmth." It also states: "Where Cold dominates, use Pungent-Hot substances to level it." This refers to tonifying Fire. Heart is above, Kidney below, Liver left, Lung right, but Spleen alone resides in the center. If Central Qi is empty, the Four Zang organs cannot generate each other. With this formula to regulate it, the Mother of All Things (Spleen) is stabilized, and the Four Zang organs receive nourishment. Hence it is called Lizhong Tang (Decoction for Regulating the Middle). Removing Ren Shen (Ginseng Radix) and Bai Zhu (Atractylodis Macrocephalae Rhizoma) makes it Sini Tang (Frigid Extremities Decoction), designed for patients with cold extremities.
