《巢氏病源》温疟候∶夫温疟与寒疟安舍？温疟者，得之冬中于风寒，寒气藏于骨髓之中，至春则阳气大发，
邪气不能出，因遇大暑，脑髓烁，脉肉消释，腠理发泄，因有所用力，邪气与汗皆出。此病藏于肾，其气先从
内出之于外。如此则阴虚而阳盛，则病衰，气复反入，入则阳虚，阳虚则寒矣。故先热而后寒，名曰温疟。疟
先寒而后热，此由夏伤于暑，汗大出，腠理开发，因遇夏气，济沧之水寒，寒之藏于腠理皮肤之中，秋气伤于
风，则病盛矣。夫寒者，阴气也；风者，阳气也。先伤于寒，而后伤于风，故先寒而后热。先伤于风，而后伤
于寒，故先热而后寒。亦以时作，名曰温疟。夫病疟六、七日，但见热者，温疟也。

[Source: Chao's Pathogenesis of Diseases, "Warm Malaria" Section] What is the distinction between warm malaria and cold malaria? Warm malaria arises from contracting wind-cold in winter. The cold pathogen hides within the bone marrow. When yang qi expands vigorously in spring, the pathogenic factor cannot exit. If subsequently exposed to intense summer heat, the brain marrow is scorched, vessels and flesh are diminished, and the couli (pores) open and sweat is released. If physical exertion occurs at this time, the pathogen exits along with the sweat. This disease resides in the Kidney; its qi first emerges from the interior to the exterior. Consequently, yin becomes deficient while yang becomes excessive. As the illness wanes, the qi reverses and re-enters the interior. Upon entering, yang becomes deficient, leading to coldness. Thus, it presents with fever first followed by chills, named "warm malaria."
If malaria presents with chills first followed by fever, this results from summerheat injury in summer. Profuse sweating opens the couli. Exposure to cold water during summer allows cold to hide within the couli and skin. Autumn wind then injures the body, exacerbating the disease. Cold belongs to yin qi; wind belongs to yang qi. Injury by cold first, then by wind, results in chills first, then fever. Injury by wind first, then by cold, results in fever first, then chills. It also occurs at specific times and is also called "warm malaria." If malaria persists for six or seven days with only fever present, it is warm malaria.
Qianjin Fang Changshan Decoction: A formula for treating pediatric warm malaria.
Changshan (Dichroa Radix, 1 liang, sliced) Xiaomai (Tritici Fructus, 3 he) Danzhuye (Lophatheri Herba, sliced, 1 sheng. Waitai uses one handful).
The above three ingredients are boiled in 1 sheng of water until reduced to 5 he. For infants aged one day to seven days, administer 1 he divided into three doses. For infants aged eight to fifteen days, administer 1.5 he divided into three doses. For infants aged sixteen to twenty days, administer 3 he divided into three doses. For infants aged forty to sixty days, administer 6 he divided into three doses. For infants aged sixty to one hundred days, administer 2.5 he per dose. For infants aged one hundred to two hundred days, administer 3 he per dose. The formula in Waitai is identical but specifies increasing the water volume for children aged one to seven or eight years, using this as a standard ratio.
Another Qianjin Fang:
Use Luji Mo (Cervi Cornu Degelatinatum powder). Administer one qianbi immediately upon the onset of an attack.
Another Qianjin Fang:
Use Biejia Hui (Testudinis Carapax et Plastrum ash). Administer one qianbi with wine. At the time of the attack, administer three qianbi, and apply moxibustion to the body.
Another Qianjin Fang:
Burn the yellow skin inside the chicken (Jizhong Huangpi), grind into powder, and mix with milk for administration. Use male chickens for boys and female chickens for girls.
Qianjin Moxibustion Method: For pediatric warm malaria, moxa the point located one finger-width below the nipple, applying three moxa cones (zhuang).
