（《局方》藿香正气散）治疗外感风寒、内伤饮食所致的憎寒壮热、头痛呕吐逆气、胸膈满闷、咳嗽气喘。以及寒湿侵袭、疟疾、中暑、霍乱吐泻，感受山岚瘴气等不正之气者，均可根据情况加减使用。（元气虚弱之人慎用，以免耗伤正气。）
组成：藿香、紫苏、白芷、大腹皮、茯苓（各三两）、白术（土炒）、陈皮、半夏曲、浓朴（姜制）、桔梗、甘草。
方义解析：此药不仅能治伤寒发热脉沉、元气虚弱之证，亦能治吐泻转筋。其中藿香、紫苏、白芷辛温发散，以散寒利膈；茯苓、白术、甘草健脾益气，以祛除湿邪；陈皮、半夏曲、浓朴理气化痰，以消滞气和胃；桔梗宣肺利咽。诸药合用，共奏解表化湿、理气和中之功。若伤食较重者，可加山楂、神曲等消食药。
（六和汤）治疗夏季饮食不调，内伤生冷食物，外受暑气侵袭，导致寒热交替发作、霍乱吐泻。以及伏暑引起的烦闷、倦怠嗜卧、口渴、小便赤黄、饮酒中毒等症状。
组成：砂仁、藿香、浓朴、杏仁、半夏、扁豆、木瓜、人参、白术、赤茯苓、甘草，煎服时加入生姜、大枣。
方义解析：藿香、砂仁、杏仁、浓朴气味芳香，能舒展脾气，辛味能行气宽中。其中砂仁、浓朴兼能化食消积；木瓜味酸，能平肝舒筋。人参、白术、茯苓、甘草健脾渗湿，调和诸药。生姜、大枣发散表邪，调和营卫。全方旨在“和”字，即调和脾胃与周身气血。吴鹤皋曰：“六和者，和六腑也。脾胃为六腑之总司，先调脾胃，则水精四布，五经并行，百骸九窍，皆太和矣。”
（三解汤）治疗时行疟疾的通用方剂。（喻嘉言曰：疟疾发作必然有寒有热。这是因为外邪潜伏于半表半里之间，恰好在少阳经的界限。邪气外出与阳气相争，阴胜则恶寒；邪气入内与阴气相争，阳胜则发热。即使是纯热无寒的瘅疟、温疟，或纯寒无热的牝疟，其病机根源也都自少阳经发展至极偏之处。要补偏救弊，必须使病势返还至少阳经的界限，使阴阳协和才能痊愈。可以说疟疾可能兼及其他经络，但如果说其他经络而不涉及少阳，那就不能称之为疟疾了。脉象虽然多变，但“弦”这一脉象特征，实则贯穿始终。）
方义解析：疟邪藏匿于分肉之间，邪正之气相互斗争。邪气并于体表则在表，并于体内则在里。若未完全并表或并里，则处于半表半里之间。
(Ju Fang Huoxiang Zhengqi San) Treats conditions caused by external contraction of wind-cold and internal injury from diet, manifesting as aversion to cold with high fever, headache, vomiting and regurgitation, fullness and oppression in the chest and diaphragm, cough and asthma. It is also suitable for cases involving cold-dampness invasion, malaria, heatstroke, cholera with vomiting and diarrhea, and infection by miasma or noxious qi from mountainous areas. Dosage should be adjusted according to the specific condition. (Use with caution in individuals with deficient Yuan Qi, as it may further deplete healthy energy.)
Ingredients: Huoxiang (Agastache Herba), Zisu (Perilla Folium), Baizhi (Angelicae Dahuricae Radix), Dafupi (Arecae Pericarpium), Fuling (Poria), Baizhu (Atractylodis Macrocephalae Rhizoma - stir-fried with soil), Chenpi (Citri Reticulatae Pericarpium), Banxiaqu (Pinelliae Tuber Fermentatum), Nongpo (Magnoliae Officinalis Cortex - processed with ginger juice), Jiegeng (Platycodonis Radix), Gancao (Glycyrrhizae Radix et Rhizoma). Each ingredient is used in a dosage of three liang, except where specified otherwise.
Analysis of Formula Action: This formula treats febrile diseases with deep pulse due to cold damage and deficient Yuan Qi, as well as vomiting, diarrhea, and muscle twitching. Huoxiang, Zisu, and Baizhi are acrid and warm, dispersing cold and benefiting the diaphragm; Fuling, Baizhu, and Gancao strengthen the Spleen and eliminate dampness; Chenpi, Banxiaqu, and Nongpo regulate Qi and transform phlegm to resolve stagnation and harmonize the Stomach; Jiegeng diffuses the Lung and benefits the throat. Together, they achieve the effects of releasing the exterior, transforming dampness, regulating Qi, and harmonizing the middle. For severe food stagnation, add Shan Zha (Crataegi Fructus) and Shen Qu (Massa Medicata Fermentata) to promote digestion.
(Liuhe Tang) Treats summer months' dietary irregularities, internal injury from raw and cold foods, and external invasion of summer-heat qi, leading to alternating chills and fever, cholera with vomiting and diarrhea. It also addresses symptoms such as stifling sensation due to latent summer-heat, fatigue and desire to lie down, thirst, dark urine, and alcohol intoxication.
Ingredients: Sharen (Amomi Fructus), Huoxiang (Agastache Herba), Nongpo (Magnoliae Officinalis Cortex), Xingren (Armeniacae Semen Amarum), Banxia (Pinelliae Tuber), Bian Dou (Dolichoris Lablab Semen), Mugua (Chaenomelis Fructus), Renshen (Ginseng Radix et Rhizoma), Baizhu (Atractylodis Macrocephalae Rhizoma), Chifuling (Poria with Red Core), Gancao (Glycyrrhizae Radix et Rhizoma). Decoct with fresh Ginger (Shengjiang) and Jujube (Dazao).
Analysis of Formula Action: Huoxiang, Sharen, Xingren, and Nongpo have aromatic qualities that soothe the Spleen and acrid properties that move Qi. Sharen and Nongpo additionally transform food stagnation; Mugua is sour, calming the Liver and relaxing sinews. Renshen, Baizhu, Fuling, and Gancao strengthen the Spleen and leach out dampness, harmonizing the various herbs. Ginger and Jujube disperse the exterior and harmonize Ying and Wei. The entire formula aims at "harmonization," specifically harmonizing the Spleen and Stomach with the rest of the body. Wu Hegao stated: "Liuhe means harmonizing the six Fu organs. The Spleen and Stomach are the generals of the six Fu organs. By first regulating the Spleen and Stomach, water and essence distribute to all parts, the five meridians flow smoothly, and all limbs and orifices attain great harmony."
(Sanjie Tang) A general formula for treating epidemic malaria. (Yu Jiayan stated: Malaria attacks must involve both chills and fever. This is because external pathogens lie dormant between the interior and exterior, precisely at the boundary of the Shaoyang channel. When the pathogen moves outward and contends with Yang, Yin prevails causing chills; when it moves inward and contends with Yin, Yang prevails causing fever. Even pure-heat without chills (Dan Malaria/Wen Malaria) or pure-chills without fever (Pin Malaria) originate from the Shaoyang channel reaching an extreme deviation. To correct this deviation and save the deficiency, one must return the pathological state to the Shaoyang boundary, allowing Yin and Yang to harmonize before recovery. While malaria may involve other channels, if it does not involve Shaoyang, it cannot be classified as malaria. Although the pulse may vary frequently, the "wiry" (Xian) character is fundamentally present throughout.)
Ingredients: Chaihu (Bupleuri Radix), Mahuang (Ephedrae Herba - nodes removed), Zexie (Alismatis Rhizoma). Each used in a dosage of three qian.
Analysis of Pathogenesis: The malaria pathogen hides between the muscle layers, where the pathogenic factor and healthy Qi contend. If the pathogen merges with the exterior, the manifestation is at the exterior; if it merges with the interior, the manifestation is at the interior. If it has not fully merged with either, it remains in the half-exterior, half-interior region.
