砂仁 藿香 浓朴 杏仁 半夏 扁豆 木瓜 人参 白术 赤苓 甘草 姜枣
扁豆一味，古方多用之，以其有清暑利湿、健脾之功也。予以为扁豆之性最劣，减去扁
豆、人参二味更妙。
藿香 紫苏 白芷 大腹皮 茯苓三两 白术（土炒） 陈皮 半夏曲 浓朴（姜制） 桔
梗二两 甘草一两
每服五钱。
辟秽祛邪，兼治瘴气。由其芳烈之性，足以胜之，而又兼用化痰利湿之品，以顾脾胃。
中州一和，则客邪自解矣。
柴胡 麻黄（去节） 泽泻各三钱
一日一作之疟，邪在卫；间日一作之疟，邪在营；三阴大疟，则邪在腑。皆由先受热、
后受寒所致，故阴阳交争。《内经》之训，昭然如揭日月。后人纷纷聚讼，各出己见，反致
抛荒
青皮 浓朴（醋炒） 柴胡 黄芩（炒） 半夏（姜制） 茯苓 白术（土炒） 甘草
（炙） 草果
加姜煎。
疟一症，《内经》论之甚详，从无一语及脏，可见疟邪断无入脏之理。《巢氏病源》妄
为分发，识者讥之。清脾饮，变小柴胡之制而用黄芩，盖欲其清营分之热邪，使之仍从卫出
耳。并非病在脾经清脾以治疟也。
黄连一两 茯苓二两阿胶（炒）一两
为末，水熬阿胶为丸。
黄连阿胶之法，开于仲景。但阿胶一味，所重者在井水，而不在驴皮。因济水伏流，惟
阿井通于济，故有平肝滋肾之功。后来射利之徒，更将牛、羊、猪、犬杂皮，一概入胶，败
人脾胃，不如不用为佳。
Amomum fruit (Sharen), Agastache herb (Huoxiang), Magnolia bark (Noupu), Apricot seed (Xingren), Pinellia tuber (Banxia), Lablab bean (Bian Dou), Papaya (Mugua), Ginseng root (Renshen), Atractylodes macrocephala rhizome (Baizhu), Red Poria (Chiling), Licorice root (Gancao), Ginger (Jiang), Jujube (Zao).
Lablab bean (Bian Dou) is frequently used in ancient formulas because of its ability to clear summerheat, promote diuresis to remove dampness, and strengthen the spleen. I consider Lablab bean (Bian Dou) to have the poorest medicinal nature; it is more ingenious to omit both Lablab bean (Bian Dou) and Ginseng root (Renshen).
Agastache herb (Huoxiang), Perilla leaf (Zisu), Angelica dahurica root (Baizhi), Areca peel (Dafupi), Poria (Fuling) 3 liang, Atractylodes macrocephala rhizome (Baizhu) stir-fried with soil, Tangerine peel (Chenpi), Fermented Pinellia paste (Banxiaqu), Magnolia bark (Noupu) processed with ginger, Platycodon root (Jiegeng) 2 liang, Licorice root (Gancao) 1 liang.
Take 5 qian per dose.
Expels turbidity and evil pathogens, and treats miasma. Its aromatic and potent nature is sufficient to overcome the pathogen, while simultaneously using phlegm-resolving and dampness-promoting agents to protect the spleen and stomach. Once the middle jiao harmonizes, the external pathogen resolves spontaneously.
Bupleurum root (Chaihu), Ephedra stem (Mahuang) de-jointed, Alisma rhizome (Zexie) each 3 qian.
Malaria occurring daily indicates the pathogen is in the Wei level; malaria occurring every other day indicates the pathogen is in the Ying level; severe tertian malaria indicates the pathogen is in the Fu organs. All are caused by first contracting heat and then cold, leading to a struggle between Yin and Yang. The teachings of the *Neijing* are as clear as the sun and moon. Later scholars debated endlessly, offering their own views, which only led to neglecting the classics.
Green tangerine peel (Qingpi), Magnolia bark (Noupu) stir-fried with vinegar, Bupleurum root (Chaihu), Scutellaria root (Huangqin) stir-fried, Pinellia tuber (Banxia) processed with ginger, Poria (Fuling), Atractylodes macrocephala rhizome (Baizhu) stir-fried with soil, Licorice root (Gancao) honey-fried, Tsaoko fruit (Caoguo).
Decoct with ginger.
The *Neijing* discusses malaria in great detail, never mentioning the Zang organs, indicating that the malaria pathogen absolutely does not enter the Zang organs. The *Chaoshi Bingyuan* arbitrarily classified it, which was ridiculed by knowledgeable practitioners. Qingpi Yin modifies the formula structure of Xiaochaihu Tang by using Huangqin, presumably to clear heat from the Ying level so that the pathogen may exit via the Wei level. It is not treating malaria by clearing the Spleen channel because the disease is located there.
Coptis rhizome (Huanglian) 1 liang, Poria (Fuling) 2 liang, Donkey-hide gelatin (Ejiao) stir-fried 1 liang.
Grind into powder, dissolve Ejiao in water to make pills.
The method of Huanglian Ejiao Tang was initiated by Zhang Zhongjing. However, regarding Ejiao, the emphasis lies on the well water, not the donkey skin. Because Ji River flows underground, only the waters of A Well connect with Ji River, thus possessing the function of pacifying the Liver and nourishing the Kidney. Later profit-driven individuals mixed cow, sheep, pig, and dog skins into the gelatin, damaging the Spleen and Stomach; it is better not to use it.
