《内经》云∶“阳气者，卫外而为固也”，“炅则气泄。”今暑邪干卫，故身热自汗。以黄 、
人参、甘草补中益气为君；甘草、橘皮、当归身甘辛微温养胃气，和血脉为臣。苍术、白术、泽泻渗利除湿。
升麻、葛根苦甘平，善解肌热，又以风胜湿也。湿胜则食不消而作痞满，故炒曲甘辛，青皮辛温，消食快气。
肾恶燥，急食辛以润之，故以黄柏苦辛寒，借甘味泻热补水虚者，滋其化源。以五味子、麦门冬酸甘微

此病皆因饮食失节，劳倦所伤，日渐因循，损其脾胃，乘暑天而作病也。
如汗大泄者，津脱也，急止之。加五味子（十枚），炒黄柏（五分），知母（三分）。此按而收之也。

夫脾胃虚弱之人，遇六七月霖雨，诸物皆润，人汗沾衣，身重短气，更逢湿旺，助热为邪，西北二方

黄芪（汗少者减去五分） 苍术（用米泔水浸泡去皮，以上各一钱五分） 升麻（一钱）
人参（去掉芦头） 白术 陈皮 神曲（炒制） 泽泻（以上各五分） 甘草（炙烤） 黄柏（酒浸） 当归身

《黄帝内经》说：“阳气，护卫体表而使其固密”，“热盛则气泄”。如今暑邪侵犯卫分，所以身体发热、自然出汗。以黄芪、人参、甘草补益中焦之气作为君药；甘草、陈皮、当归身味甘辛微温，养护胃气，调和血脉作为臣药。苍术、白术、泽泻渗湿利水以除湿气。
升麻、葛根味苦甘性平，善于解除肌表之热，又利用风能胜湿的原理。湿气偏胜则食物不消化而产生痞满感，所以用炒神曲味甘辛，青皮味辛温，以消食行气。
肾恶燥，急需食用辛味药物来滋润它，所以用黄柏味苦辛寒，借助甘味来泻热补水虚，滋养其化生之源。用五味子、麦门冬味酸甘微寒，作为佐药，以救治暑热对肺金（庚金）的损伤。
将上述药材捣碎，作一剂服用，加水两盏，煎煮至一盏，去渣滓，稍温热时服用，在饭后较远的时间服用。
这种病都是因为饮食不节制，劳累过度所伤，日积月累，损害了脾胃，趁着暑天而发病。
如果汗出特别大，这是津液脱失，必须紧急止汗。加五味子（十枚），炒黄柏（五分），知母（三分）。这是通过收敛的方法来止汗。
如果湿热侵袭肝肾，导致行走不稳，脚膝痿软无力，双脚歪斜，已经中了痿证邪气，加酒洗黄柏、知母（以上各五分），使双脚涌出气力。
如果大便涩滞，隔一两天不解，导致进食减少，这是因为血中有伏火而不能滋润肠道。加当归身、地黄（以上各五分），桃仁泥、火麻仁泥（以上各一钱），以滋润肠道。
脾胃虚弱的人，遇到七八月的连绵阴雨，万物都湿润，人出汗沾衣，身体沉重短气，再加上湿气旺盛，助长热邪成为致病因素，西北二方的寒冷清凉之气断绝了，人再次感受这种邪气，就会骨节乏力，形体如同梦寐之间，朦胧如在烟雾中，不知道自身存在一样。圣人制定法则，夏季适宜补益的是补益天真元气，而不是补益火热，夏季吃寒凉食物就是这个道理。所以用人参的甘味补气，麦门冬的苦寒泻热补水之源，五味子的酸味清肃燥金，名为生脉散。孙思邈真人说：五月常服五味子以补五脏之气，也是这个意思。
Astragali Radix (reduce by five fen if sweating is scanty) Atractylodis Rhizoma (soaked in rice water, peel removed, each above one qian five fen) Cimicifugae Rhizoma (one qian)
Ginseng Radix (remove rhizome) Atractylodis Macrocephalae Rhizoma Citri Reticulatae Pericarpium Curculinis Fructus (stir-fried) Alismatis Rhizoma (each above five fen) Glycyrrhizae Radix et Rhizoma (honey-fried) Phellodendri Cortex (wine-soaked) Angelicae Sinensis Radix
Ophiopogonis Radix (remove heart) Aurantii Fructus Immaturus (remove white pith) Puerariae Radix (each above three fen) Schisandrae Fructus (nine pieces)
The *Neijing* states: "Yang qi guards the exterior and maintains consolidation," and "Heat causes qi to leak." Currently, summer-heat pathogen invades the Wei (Defensive) level, thus causing fever and spontaneous sweating. Astragalus Radix, Ginseng Radix, and Glycyrrhizae Radix tonify Middle Jiao Qi as Sovereign drugs; Glycyrrhizae Radix, Citri Reticulatae Pericarpium, and Angelicae Sinensis Radix are sweet, pungent, and slightly warm, nourishing Stomach Qi and harmonizing Blood vessels as Minister drugs. Atractylodis Rhizoma, Atractylodis Macrocephalae Rhizoma, and Alismatis Rhizoma promote urination and drain dampness.
Cimicifugae Rhizoma and Puerariae Radix are bitter, sweet, and neutral, excellently resolving muscle-layer heat, and utilizing wind to overcome dampness. When dampness prevails, food fails to digest leading to fullness and stagnation, therefore stir-fried Curculinis Fructus (sweet and pungent) and Aurantii Fructus Immaturus (pungent and warm) are used to digest food and move Qi.
The Kidney dislikes dryness; urgently consuming pungent substances moistens it. Therefore, Phellodendri Cortex (bitter, pungent, cold) is used, borrowing the sweet flavor to clear heat and replenish fluid deficiency, nourishing its source of transformation. Schisandrae Fructus and Ophiopogonis Radix (sour, sweet, slightly cold) serve as Assistant drugs to rescue Lung Metal (Geng Metal) injured by summer heat.
Crush the above herbs into coarse powder. Take one dose, add two cups of water, decoct until one cup remains, remove dregs, and take slightly warm after a considerable time post-meal.
This disease arises from irregular diet and overexertion damaging the Spleen and Stomach over time, manifesting during the summer season.
If sweating is profuse, it indicates loss of Body Fluids; stop it urgently. Add Schisandrae Fructus (ten pieces), stir-fried Phellodendri Cortex (five fen), and Anemarrhenae Rhizoma (three fen). This is the method of astringing to collect.
If damp-heat attacks the Liver and Kidney, causing unsteady gait, flaccidity and weakness of legs and knees, and deviation of both feet, indicating invasion by Flaccidity syndrome pathogen, add wine-washed Phellodendri Cortex and Anemarrhenae Rhizoma (each five fen) to restore strength to the feet.
If stool is constipated and difficult to pass for one or two days, leading to reduced appetite, this is due to latent fire in the Blood preventing lubrication. Add Angelicae Sinensis Radix and Rehmanniae Radix (each five fen), Persicae Semen paste, and Cannabis Fructus paste (each one qian) to moisten.
In individuals with Spleen and Stomach deficiency, encountering continuous rain in July and August, where all things become moist, sweat soaks clothes, body feels heavy and short of breath, combined with abundant dampness assisting heat to become pathogenic, the cold and clear Qi of the northwest regions ceases. Upon re-exposure to this pathogen, bones lack strength, the form seems like being in a dream, hazy as if in smoke, unaware of one's own existence. The Sages established laws: in summer, supplementation should tonify innate Yuan Qi, not supplement fire-heat; eating cold foods in summer exemplifies this. Thus, Ginseng Radix's sweetness tonifies Qi, Ophiopogonis Radix's bitterness and cold clear heat and replenish fluid sources, and Schisandrae Fructus's sourness clears and descends Dryness Metal, named Shengmai San (Generate the Pulse Powder). Sun Simiao stated: "Take Schisandrae Fructus regularly in May to tonify the Qi of the Five Zang organs," which shares this intent.
