夫胃主纳受，脾主运动。脾虚，谷气不克，脾愈无所禀矣。脾运四肢，既禀气有亏，则四肢
倦怠而嗜卧也。有食后体倦瞌睡者，乃脾虚不能运化而然，皆当补脾理胃，兼消导自安。脉沉无
力，右关细濡为倦怠。
主方 人参（五分） 白术 茯苓 黄 山药 山楂 麦芽（各一钱） 炙草（三分）

生脉散 治倦怠嗜卧，口干少神（方见暑门）。
（附∶恶心）
经曰∶诸逆冲上，皆属于火。诸呕吐酸，暴注下迫，皆属于热。又曰∶寒气客于肠胃，厥逆
上出，故痛而呕。是证总属胃气不和，然有寒、热、痰、食、风邪、气逆、久病胃虚之异，必当
详辨。胃寒者，恶寒恶食。朝餐暮吐，清水涎沫。喜热物，脉沉迟。胃热者，食入即呕，躁闷烦渴
，吐味酸苦，思食冷物，脉洪大。痰饮则吐有痰涎，食积则胀嗳酸腐，风邪则暴发而甚，气逆则
胸膈郁遏，胃虚则不能纳食，各以脉理参酌。呕属阳明，有声有物，宜生姜为主；吐属太阳，有
物无声，陈皮为主；哕属少阳，有声无物，半夏为主。

The Stomach (Wei) is responsible for receiving and accepting food, while the Spleen (Pi) is responsible for transportation and transformation. If Spleen Qi is deficient, it cannot adequately transform grain Qi, leading to further depletion of what the Spleen receives. The Spleen governs the movement of the four limbs; since the Qi received is deficient, this results in fatigue of the four limbs and a tendency to sleep excessively. Some individuals feel body fatigue and drowsiness after eating, which is due to Spleen deficiency failing to transport and transform properly. Treatment should generally tonify the Spleen and regulate the Stomach, combined with promoting digestion and removing stagnation, so that comfort will naturally return. A pulse that is deep and forceless, with a fine and soggy quality at the Right Guan position, indicates fatigue.
Main Formula: Renshen (Ginseng Radix) (5 fen), Baizhu (Atractylodis Rhizoma), Fuling (Poria), Huangqi (Astragali Radix), Shanyao (Dioscoreae Rhizoma), Shanzha (Crataegi Fructus), Maiya (Hordei Fructus Germinatus) (each 1 qian), Zhigancao (Prepared Glycyrrhizae Radix et Rhizoma) (3 fen). Add three slices of Shengjiang (Zingiberis Rhizoma Recens) and one Zaoju (Jujubae Fructus).
For obese persons, add Chenpi (Citri Reticulatae Pericarpium), Banxia (Pinelliae Rhizoma), Cangzhu (Atractylodis Rhizoma), Shengma (Cimicifugae Rhizoma), and Chaihu (Bupleuri Radix); for thin persons, add Danggui (Angelicae Sinensis Radix), Huangqin (Scutellariae Radix), and Lianlian (Coptidis Rhizoma); for indigestion, take Baohe Wan (see Food Stagnation section).
Shengmai San: Treats fatigue, excessive sleepiness, dry mouth, and lack of spirit (see Summerheat section).
(Attachment: Nausea)
The Classics state: All rebellious Qi rushing upward belongs to Fire. All vomiting of sour fluid, sudden diarrhea with tenesmus, belong to Heat. It also states: When Cold Qi lodges in the intestines and stomach, causing Jue Ni (rebellious counterflow) to rush upward, pain and vomiting occur. These symptoms generally belong to Disharmony of Stomach Qi, but there are differences among Cold, Heat, Phlegm, Food Stagnation, Wind Pathogen, Qi Rebelliousness, and chronic illness leading to Stomach Deficiency, which must be carefully distinguished. In Stomach Cold, there is aversion to cold and food; morning intake leads to evening vomiting of clear water and saliva; preference for hot substances; pulse is deep and slow. In Stomach Heat, food is vomited immediately upon entry; restlessness, oppression, irritability, and thirst occur; vomitus tastes sour and bitter; desire for cold substances; pulse is surging and large. Vomiting due to Phlegm-Fluid involves spitting up phlegm and saliva; vomiting due to Food Stagnation involves abdominal distension and belching with sour/rotten odors; vomiting due to Wind Pathogen is sudden and severe; vomiting due to Qi Rebelliousness involves chest and diaphragmatic oppression; vomiting due to Stomach Deficiency involves inability to accept food. Each case must be weighed by pulse diagnosis.

Add seven slices of Shengjiang (Zingiberis Rhizoma Recens) and two Zaoju (Jujubae Fructus). Decoct in water, add Jiangzhi (Zingiberis Rhizoma Juice), and take orally. For those unable to swallow medicine, crush fresh Shengjiang finely, soak Chenpi and fried Nuomi (Oryza Sativa Var. Glutinosa Semen) in water to make a decoction.

For all vomiting cases with extreme thirst, drink Tongbian (Child's Urine); do not drink water, Ginger Soup, or cold beverages. In summer, use Wuling San (Five-Ingredient Powder with Poria) plus Chenpi (Citri Reticulatae Pericarpium), Banxia (Pinelliae Rhizoma), and Shengjiang (Zingiberis Rhizoma Recens). For deficient persons with confusion, decoct 1 liang of Renshen (Ginseng Radix) to drink, or cook with rice into porridge.
