Yu, female, 15 years old, first consultation on June 20, 1976. Chief complaint: Due to a common cold last month, high fever around 38.5℃, after using antipyretic analgesics and antibiotics, the high fever has subsided, but there is still low-grade fever, with a daily temperature around 37.5℃ for more than twenty days. Chest X-ray, anti-"O" test, blood routine, and urine routine tests showed no abnormalities. Previously used clearing heat and removing toxin Chinese medicinals without effect.

Currently experiencing headache, fatigue, lack of strength, poor appetite, normal bowel movements. Observation shows a shallow yellow complexion, listless spirit; tongue texture is pale red with thin white coating; pulse diagnosis shows floating and slow at the inch position, weak and faint at the chi position. This is due to incomplete elimination of pathogens after a common cold, leading to disharmony between nutrient and defensive qi and causing fever. The treatment plan is to use the method of releasing flesh to reduce fever, following the original formula of Zhang Zhong-jing's Cinnamon Twig Decoction.
Cinnamon Twig 10g, Peony Root 15g, Liquorice Root 10g, Fresh Ginger Rhizome 3 slices, Chinese Date 3 pieces
Decocted with water, instructed to take 2 doses. After taking 1 dose, the fever subsided and did not recur thereafter.
