疟发时，热多寒少，口苦咽干，大小赤涩，脉来弦数者，此方主之。
此条皆太阴证也，太阴脾主湿，湿生痰，痰生热，故见上件诸证。脉来弦数，弦为痰饮
，数为热也。方曰清脾者，非清凉之谓，乃攻去其邪而脾部为之一清也。故青皮、浓朴清去
脾部之痰，半夏、茯苓清去脾中之湿，柴胡、黄芩清去脾中之热，白术、甘草清去脾脏之虚，
而
《机要》云∶疟在三阴经，总谓之湿疟，当从太阴经论之。此言可谓知要。今即古方审择而
用焉，则本方为切当矣。

《伤寒例》云∶若脉阴阳俱盛，重感于寒者，变为温疟。温疟先热后寒，宜此方主之。
脉阴阳俱盛者，旧有热也。重感于寒者，新有寒也。凡疟寒热相搏，邪正分争，并于表
，则阳实而阴虚，阴虚生内热，阳实生外热，中外皆热，故见其烦渴而身热，恶热莫任也；
并于里，则阴实而阳虚，阳虚生外寒，阴实生内寒，中外皆寒，故见其鼓颔而战栗，恶寒莫
任也；若其邪正分争，并之未尽，则寒热交集，鼓颔战栗，烦渴身热并至矣。此论常疟寒热
之理也。温疟先热后寒者，以其先有旧热而后伤寒也。方中有麻黄、杏仁，可以解重感之寒；

当疟疾发作时，发热多而恶寒少，口苦咽干，小便短赤涩痛，脉象弦数，此方主治。
这一条论述的都是太阴证。太阴脾主司湿气，湿气生痰，痰郁化热，所以出现上述各种症状。脉象弦数，弦脉主痰饮，数脉主热。方名“清脾”，并非指清凉之意，而是指攻除病邪使脾部得以清净。因此，青皮、浓朴清除脾部的痰湿，半夏、茯苓清除脾中的湿气，柴胡、黄芩清除脾中的热邪，白术、甘草补益脾脏的虚损。
《机要》说：疟疾在三阴经发病，总称为湿疟，应当从太阴经来论治。这番话可谓抓住了要领。如今审视并选用古方，那么本方最为恰当。

《伤寒例》说：如果脉象寸关尺三部都盛大，又再次感受寒邪，就会变为温疟。温疟先发热后恶寒，适宜用此方主治。
脉象阴阳俱盛，说明体内原本就有热邪。再次感受寒邪，说明新近有寒邪侵袭。凡是疟疾寒热交争，邪气与正气相搏，若邪气并聚于表，则阳气实而阴气虚，阴虚产生内热，阳实产生外热，内外皆热，所以出现烦躁口渴和身体发热，难以忍受怕热；若邪气并聚于里，则阴气实而阳气虚，阳虚产生外寒，阴实产生内寒，内外皆寒，所以出现下巴打颤和战栗，难以忍受怕冷；如果邪正分争，邪气并未完全聚集，则寒热交错，下巴打颤战栗，烦躁口渴身体发热同时出现。这是论述普通疟疾寒热变化的原理。温疟先发热后恶寒，是因为先有旧有的热邪而后又感受了寒邪。方中含有麻黄、杏仁，可以解除再次感受的寒邪；含有……

When malaria attacks, with more heat and less cold, bitter taste in the mouth, dry throat, dark and scanty urine, and a wiry and rapid pulse, this formula is indicated.
This clause discusses Taiyin syndrome. The Spleen of Taiyin governs dampness; dampness generates phlegm, and phlegm generates heat, thus presenting the aforementioned symptoms. A wiry pulse indicates phlegm-fluid retention, and a rapid pulse indicates heat. The name "Qingpi" (Clear the Spleen) does not mean cooling, but rather clearing the pathogenic factors so that the Spleen region becomes clear. Therefore, Qingpi and Houpo clear phlegm from the Spleen region; Banxia and Fuling clear dampness from the Spleen; Chaihu and Huangqin clear heat from the Spleen; Baizhu and Gancao tonify the deficiency of the Spleen organ.
The *Jiyao* states: Malaria affecting the three Yin meridians is generally called Damp Malaria and should be discussed according to the Taiyin meridian. This statement captures the essence. By examining and selecting ancient formulas for use today, this original formula is most appropriate.

The *Shanghan Li* states: If the pulses at the cun, guan, and chi positions are all full and surging, and one is re-exposed to cold, it transforms into Wenmalaria (Warm Malaria). Warm Malaria presents with heat first followed by cold, and this formula is indicated.
A full and surging pulse at both yin and yang positions indicates pre-existing internal heat. Re-exposure to cold indicates new external cold invasion. In general, when malaria involves the struggle between cold and heat, with pathogens and healthy qi contending, if the pathogen aggregates at the exterior, Yang becomes excess and Yin becomes deficient. Yin deficiency generates internal heat, while Yang excess generates external heat, resulting in heat throughout the interior and exterior, thus presenting with irritability, thirst, and fever, making intolerance to heat unbearable. If the pathogen aggregates at the interior, Yin becomes excess and Yang becomes deficient. Yang deficiency generates external cold, while Yin excess generates internal cold, resulting in cold throughout the interior and exterior, thus presenting with chattering teeth and shivering, making intolerance to cold unbearable. If the pathogen and healthy qi contend without complete aggregation, cold and heat intersect, causing simultaneous chattering teeth, shivering, irritability, thirst, and fever. This discusses the principle of cold and heat fluctuations in common malaria. Warm Malaria presents with heat first and cold later because there is pre-existing internal heat followed by exposure to cold. The formula contains Mahuang and Xingren, which can resolve the newly acquired cold; it contains...
