治疗实证疟疾长期发作不止，脉象寸口弦滑（浮大脉中，弦脉主肝风，滑脉主痰，浮脉主表证，大脉主阳盛。若脉象沉涩、微细者禁用），不论鬼疟、食疟，均予以治疗。
常山（酒炒）、草果（煨制）、槟榔、青皮、厚朴、陈皮、甘草，各等分。使用酒和水各一钟，煎煮至熟，用丝棉覆盖药碗（在疟疾发作时服药，因为此时正气发散而服药，反而能助长寒热邪气）。
此方是足少阳胆经和足太阴脾经的药物。常山能涌吐老痰和积饮，槟榔能下行消除食积和痰结，草果能消除太阴脾经膏粱厚味所生的陈痰。（《玉机微义》说：上方乃是温脾燥烈的药物，大概是作为脾寒来治疗的。使用它有效，是因为正值患者阴阳相并，脾气郁结，浊液凝结成痰，闭塞中脘，因此得到燥热之性，暂时得以开通，所以气通而痰止；如果中气虚弱，体内有郁火的人，再使用燥热之药，会更加劫伤正气导致虚损，过错归咎于谁呢？杨仁斋说：疟疾有水饮和瘀血两种，只有水饮才会导致寒热往来，只有瘀血才会导致憎寒发热。常山确实能逐水，如果是血证，应当加五灵脂、桃仁作为佐使，加入生姜、蜂蜜同煎；如果没有行血的药物，怎么能收到十全的效果呢？《保命集》说，夜间发作的疟疾，是邪气深远进入血分，属于阴……）
消，是指消散积滞；导，是指行气。脾虚不能运化，则气机不流行；气机不流行，则停滞而形成积滞；或者表现为泄泻痢疾，或者形成症痞，以致饮食减少，五脏得不到滋养，血气日益虚衰，因而导致危困的情况很多了，所以必须……施治者……

Treats persistent malaria of excess type, with the pulse at the cun position being wiry and slippery (in a floating and large pulse, a wiry quality indicates Liver wind, a slippery quality indicates Phlegm, a floating quality indicates exterior syndrome, and a large quality indicates Yang. It is contraindicated if the pulse is deep, choppy, faint, or fine). It treats all types, whether Ghost Malaria or Food Malaria.
Chanshan (Stemona Root, wine-fried), Caoguo (Tsaoko Cardamom Fruit, baked), Binglang (Areca Seed), Qingpi (Green Tangerine Peel), Houpo (Magnolia Bark), Chenpi (Aged Tangerine Peel), Gancao (Licorice Root) in equal parts. Use one cup of wine and one cup of water, decoct until ready. Cover the bowl with silk cotton [Note: The original text implies taking the medicine during an attack, but notes that doing so when Qi is dispersing may exacerbate cold and heat].
This formula consists of herbs for the Foot-Shaoyang Gallbladder and Foot-Taiyin Spleen meridians. Chanshan can induce vomiting to expel old Phlegm and accumulated fluids; Binglang can descend and resolve food stagnation and Phlegm knots; Caoguo can eliminate chronic Phlegm generated from rich foods affecting the Taiyin Spleen. (*Yuji Wei Yi* states: The above formula consists of warming and drying, acrid-hot herbs, presumably treating Spleen Cold. Its efficacy lies in cases where Yin and Yang are conflicting, Spleen Qi is stagnant, turbid fluids congeal into Phlegm, blocking the Zhongwan region; thus, the drying-heat properties temporarily open the blockage, allowing Qi to flow and Phlegm to cease. However, if the Middle Qi is deficient or there is internal constrained Fire, using drying-heat herbs will further deplete the body's Qi, leading to greater deficiency—who would bear the blame? Yang Renzhai states: Malaria involves both Water-Fluids and Blood Stasis. Only Water-Fluids cause alternating chills and fever; only Blood Stasis causes aversion to cold and fever. Chanshan indeed drives out Water-Fluids. If it is a Blood Stasis pattern, Wulingzhi (Trogopterus Dung) and Taoren (Peach Kernel) should be added as assistants, along with Shengjiang (Fresh Ginger) and Fengmi (Honey) for decoction; without blood-invigorating agents, how can perfect efficacy be achieved? *Baoming Ji* states: Malaria occurring at night indicates the pathogen has penetrated deeply into the Blood level, belonging to Yin...)
Xiao (Eliminate/Disperse) refers to dissipating accumulations; Dao (Guide/Lead) refers to promoting Qi movement. When Spleen deficiency fails to transport, Qi does not circulate freely; when Qi does not circulate, it stagnates and forms accumulations; this may manifest as diarrhea or dysentery, or form masses and fullness, leading to reduced dietary intake. As the Five Zang organs lose their nourishment, Qi and Blood gradually decline, often resulting in critical conditions. Therefore, one must... practitioners...
