Nest's Pathogenesis of Diseases (Chao Shi Bing Yuan): Pediatric warm diseases occur when, during the severe cold of winter, individuals are exposed to cold pathogens. The cold qi enters the muscles but does not manifest immediately; it emerges in spring when warmed by the seasonal heat, presenting with headache and high fever, termed "warm disease" (Wen Bing). Furthermore, if winter should be cold but instead becomes warm, this abnormal qi injures the body and causes immediate onset, also resulting in headache and high fever, termed "winter-warm disease" (Dong Wen Bing). Generally, pathogenic factors injure the body through exposure and contact, which is how infection occurs. Although children cannot actively expose themselves to pathogens, if the wet nurse is negligent in holding or caring for the child and fails to avoid wind pathogens and extreme hot or cold air, the child will become infected.

Nest's Pathogenesis of Diseases: Prognosis of Diarrhea in Pediatric Warm Disease: Diarrhea caused by warm disease arises from pre-existing deficiency in the intestines and stomach, combined with infection by warm-heat pathogens. Heat qi enters the intestines and stomach, clashing with food and fluids. Due to intestinal deficiency, diarrhea ensues.

Nest's Pathogenesis of Diseases: Prognosis of Epistaxis in Pediatric Warm Disease: Epistaxis in warm disease occurs when heat penetrates the qi level and enters the blood level. The Lung governs the skin and hair, controls Qi, and opens into the nose. In warm disease, pathogenic factors first lodge in the skin and clash with Qi, condensing into heat. This heat then invades the blood; blood heated becomes fluid and scatters. When blood flows out from the nose, it is called epistaxis. In observing febrile diseases, if the nose appears dry and prone to bleeding, and repeated sweating fails to produce sweat, or if no sweat has occurred since the initial infection accompanied by dry nose, panting, and noisy respiration, epistaxis is inevitable. If a child bleeds one sheng plus several he, the heat may subside; however, if bleeding reaches one dou plus several sheng, death will result.

Nest's Pathogenesis of Diseases: Prognosis of Chest Binding in Pediatric Warm Disease: For warm-heat diseases, after four or five days, if heat enters the interior causing internal heat and abdominal fullness, purgation should be employed. However, if purgation is used prematurely before heat has entered the interior, it causes interior deficiency and rebellious Qi, leading heat to bind above the chest, resulting in chest oppression, fullness, and shortness of breath, termed "chest binding" (Jie Xiong).

Zhang Zhongjing discussed that injury by cold in winter leads to warm disease in spring.

Zhuang Family Tradition: In spring, when epidemic qi is about to arise, symptoms include Qi stagnation, aversion to wind, phlegm-cough, dizziness, nasal coldness, and chest stuffiness. This is the manifestation of the disease. One should first treat with Gan Gui Tang (Licorice and Cinnamon Decoction). Whenever spring Qi moves, use this decoction to dispel pathogens, regardless of adult or child. This formula was passed down from Zhao Yanzu to Du Shunfu. I obtained it while serving together with Du Jizi and Ji Yang in Weishi County. Originally named "Wu Hu," I disliked the name and changed it to "Gan Gui Tang."

Combine the residues of two doses to decoct once more as one dose. In the year Renchen of Zhenghe Era (1112 AD), I was in Liyang. Epidemic disease was rampant that spring; all children who took this medicine were spared.
