Measles have erupted, yet the body remains hot; this is due to the accumulation and obstruction of toxic heat. During the eruption stage, Huadu Qingbiao Ji (Detoxifying and Exterior-Resolving Agent) should be used for treatment; after the rash has subsided, Chaihu Qingre Jian (Bupleurum Heat-Clearing Decoction) should be used if fever persists.
Note: Measles cannot erupt without heat. If the rash has fully erupted, the fever should subside. If high fever persists, it indicates that the pathogenic toxin is abundant and obstructive; Huadu Qingbiao Tang (Detoxifying and Exterior-Resolving Decoction) is appropriate for treatment. If the body remains febrile after the rash has faded and fallen, it signifies residual heat lingering in the muscle layer; Chaihu Qingre Yin (Bupleurum Heat-Clearing Drink) is appropriate for treatment.

Formula Song: After measles fade and heat does not diminish, Chaihu Qingre proves effective as an immortal; Chai Hu, Huang Qin, Chi Shao, Sheng Di, Mai Dong, Di Gu Pi, Zhi Mu, Gan Cao.
Toxic heat is abundant internally and flares upward, disturbing the Heart and Stomach, thereby increasing irritability and thirst. Before eruption, Shengma Gegen Tang (Ephedra and Kudzu Root Decoction) with modifications is indicated; after eruption, Baihu Tang (White Tiger Decoction) is prioritized; after subsidence, Zhuye Shigao Tang (Bamboo Leaf and Gypsum Decoction) is used. Treatment must be adapted to the timing without delay.
Note: Irritability and thirst accompanying measles indicate abundant toxic heat. The Heart disturbed by heat causes irritability; the Stomach constrained by heat causes thirst. Before eruption, Shengma Gegen Tang (Ephedra and Kudzu Root Decoction) should be added with Mai Dong (Ophiopogonis Tuber) and Tian Hua Fen (Trichosanthis Radix); after eruption, Baihu Tang (White Tiger Decoction) is suitable; after subsidence with irritability and thirst, Zhuye Shigao Tang (Bamboo Leaf and Gypsum Decoction) is used.
