Measles have erupted but the body remains hot; this is due to the congestion and obstruction of toxic heat. When the rash is erupting, use Huadu Qingbiao Jia (Detoxifying and Surface-Clearing Agent); after the rash subsides, use Chaihu Qingre Jian (Bupleurum Heat-Clearing Decoction).
[Annotation]
Measles require heat to erupt. If the rash has fully emerged, the fever should subside. If high fever persists, it indicates excessive toxic heat causing congestion and obstruction; Shihua Qingbiao Tang (Transform Toxin and Clear Exterior Decoction) is appropriate for treatment. If the rash has subsided and fallen off but the body remains hot, this indicates residual heat lingering in the muscle layer; Chaihu Qingre Yin (Bupleurum Heat-Clearing Drink) is appropriate for treatment.

Toxic heat is abundant internally and flares upward, disturbing the Heart and Stomach, adding to irritability and thirst. Before eruption, use Shengma Gegen Tang (Ephedra and Pueraria Decoction) with modifications; after eruption, Baihu Tang (White Tiger Decoction) is the priority; after subsidence, Zhuye Shigao Tang (Bamboo Leaf and Gypsum Decoction) is used. Treat according to the timing; do not delay.
[Annotation]
Irritability and thirst accompanying measles are caused by congested and excessive toxic heat. The Heart disturbed by heat causes irritability; the Stomach constrained by heat causes thirst. Before eruption, Shengma Gegen Tang (Ephedra and Pueraria Decoction) added with Mai Dong (Ophiopogonis Radix) and Tian Hua Fen (Trichosanthis Radix) is suitable. 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.

(Baihu Tang / White Tiger Decoction): Shi Gao (Gypsum Fibrosum, calcined), Sheng Zhi Mu (Anemarrhenae Rhizoma, raw), Sheng Gan Cao (Glycyrrhizae Radix et Rhizoma, raw). Administration: Decoct with Jing Mi (Oryza Sativa, rice grain) as a guide.
(Decoction Song)
Measles erupted, often with irritability and thirst,
Baihu clears heat, recovery comes naturally.
