脾胃之虚，怠惰嗜卧，四肢不收，时值秋燥令行，湿热少退，体重节痛，口苦舌干，
食无味，大便不调，小便频数，不嗜食，食不消。兼见肺病，沥淅恶寒，惨惨不乐，面色恶
而不和，乃阳气不伸故也。当升阳益胃，名之曰升阳益胃汤。
黄 （二两） 半夏（汤洗，此一味脉涩者宜用） 人参（去芦） 甘草（炙，以上各一两） 防风
（以其秋旺，故以辛温泻之） 白芍药 羌活 独活（以上各五钱） 橘皮（连瓤，四钱） 茯苓（小
便利、不渴者勿用） 泽泻（不淋勿用） 柴胡 白术（以上各三钱） 黄连（二钱）
何故秋旺用人参、白术、芍药之类反补肺，为脾胃虚则肺最受病，故因时而补，易为力
上 咀。每服三钱，生姜五片，枣二枚，去核，水一盏，同煎至二盏，去渣，温
服，早饭、午饭之间服之。禁忌如前。其药渐加至五钱止。服药后，如小便罢而病加增剧，
是不宜利小便，当少去茯苓、泽泻。
若喜食，初一二日不可饱食，恐胃再伤，以药力尚少，胃气不得转运升发也。须薄滋味
之食，或美食，助其药力，益升浮之气，而滋其胃气也，慎不可淡食，以损药力，而助邪气
之降沉也。可以小役形体，使胃与药得转运升发，慎勿大劳役，使复伤。若脾胃得安静尤
佳。若胃气少觉强壮，少食果，以助谷药之力。经云∶五谷为养，五果为助者也。
脾胃虚弱，会导致身体倦怠、嗜睡懒动，四肢无力抬举。正值秋季燥气当令之时，湿热之气逐渐消退，出现身体沉重、关节疼痛，口苦舌干，饮食无味，大便不调，小便频数，食欲不振，食物难以消化。同时兼见肺系病症，表现为怕冷颤抖，情绪低落不乐，面色晦暗不和，这是因为阳气不能舒展的缘故。治疗应当升发阳气、补益胃气，方剂命名为升阳益胃汤。
黄芪（二两） 半夏（用汤洗过，此药脉象涩滞者适宜使用） 人参（去掉芦头） 甘草（炙烤，以上各一两） 防风（因为秋季肺气旺盛，故用辛温之性以泻其邪） 白芍药 羌活 独活（以上各五钱） 陈皮（连瓤，四钱） 茯苓（小便通利、口不渴者不要使用） 泽泻（无淋证者不要使用） 柴胡 白术（以上各三钱） 黄连（二钱）
为什么在秋季肺气旺盛时，用人参、白术、白芍药等药物反而能补益肺脏？这是因为脾胃虚弱则肺脏最先受病，所以顺应时令进行补益，容易见效。将药材切碎。每次服用三钱，加生姜五片，大枣二枚（去核），水一盏，同煎至两盏，滤去药渣，温服。在早饭和午饭之间服用。禁忌事项如前所述。药量可逐渐增加至五钱为止。服药后，如果小便通畅但病情加重，说明不宜再利小便，应减少茯苓、泽泻的用量。
如果患者喜欢进食，初起的一两天内不可饱食，恐怕再次损伤胃气，因为此时药力尚弱，胃气还无法顺利转运升发。应当食用清淡可口的食物，或者美味的食物，以辅助药力，提升浮越之气，从而滋养胃气。千万不要吃淡而无味的食物，以免损耗药力，助长邪气的降沉之势。可以进行轻微的身体活动，使胃气和药力得以转运升发，切记不可过度劳累，以免再次受伤。如果脾胃能得到安静休养，尤其好。如果胃气稍觉强壮，可以少量吃水果，以辅助谷物和药物的力量。《内经》说：“五谷是养人的根本，五果是辅助的食物。”
Spleen-Stomach deficiency leads to lethargy, drowsiness, and inability to move the four limbs. When the dryness of autumn prevails and damp-heat gradually recedes, symptoms include heavy body, joint pain, bitter taste in the mouth, dry tongue, loss of appetite, irregular bowel movements, frequent urination, anorexia, and indigestion. Accompanying lung-related manifestations may include aversion to cold with shivering, depression, and a sallow or discordant complexion, which is due to the failure of Yang Qi to extend. The treatment principle should be to raise Yang Qi and benefit Stomach Qi; this formula is named Shengyang Yizhe Tang (Raising-Yang and Benefiting-Stomach Decoction).
Huangqi (Radix Astragali Membranacei) [2 liang], Banxia (Rhizoma Pinelliae Preparatum, washed with decoction; suitable for cases with choppy pulse), Renshen (Radix Ginseng, radix removed), Gancao (Radix Glycyrrhizae uralensis, roasted; each of the above 1 liang), Fangfeng (Radix Saposhnikoviae; used for its acrid-warm nature to drain pathogenic factors since Lung Qi is prosperous in autumn), Baishao (Radix Paeoniae Alba), Qianghuo (Rhizoma et Radix Notopterygii), Duhuo (Radix Angelicae Pubescentis; each of the above 5 qian), Chenpi (Pericarpium Citri Reticulatae, with pulp, 4 qian), Fuling (Poria; do not use if urination is unobstructed and thirst is absent), Zexie (Rhizoma Alismatis; do not use if no strangury exists), Chaihu (Radix Bupleuri), Baizhu (Rhizoma Atractylodis Macrocephalae; each of the above 3 qian), Huanglian (Rhizoma Coptidis [2 qian]).
Why are herbs such as Renshen, Baizhu, and Baishao, which tonify the Lungs, used when Lung Qi is prosperous in autumn? This is because Spleen-Stomach deficiency causes the Lungs to suffer first; therefore, tonification is performed according to the season, making it easier to achieve efficacy. Prepare the herbs by cutting them into small pieces. Take 3 qian per dose, add 5 slices of Shengjiang (Rhizoma Zingiberis Recens), 2 dates (Zao, Fructus Jujubae, pitted), and 1 cup of water. Decoct together until 2 cups remain, strain, and take warm. Administer between breakfast and lunch. Contraindications are as mentioned previously. The dosage can be gradually increased up to 5 qian. If after taking the medicine, urination becomes normal but the disease worsens, diuresis is inappropriate; reduce the dosage of Fuling and Zexie.
If the patient desires food, avoid overeating during the first one or two days to prevent further injury to the Stomach Qi, as the medicinal power is still weak and Stomach Qi cannot yet transport and ascend effectively. Consume light and palatable foods, or delicious foods, to assist the medicinal power, promote ascending and floating Qi, and nourish Stomach Qi. Avoid bland foods, as they may impair medicinal power and aid the sinking of pathogenic factors. Engage in mild physical activity to facilitate the transport and ascent of Stomach Qi and medicines; strictly avoid excessive labor to prevent re-injury. Quiet rest for the Spleen-Stomach is particularly beneficial. If Stomach Qi feels slightly strengthened, consume small amounts of fruits to assist the power of grains and medicines. As stated in the Classics: "The five grains are for nourishment, and the five fruits are for assistance."
