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，

《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；

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...
