Characterization of the chemical constituents of Jie-Geng-Tang and the metabolites in the serums and lungs of mice after oral administration by LC-Q-TOF-MS.

Jie-Geng-Tang (JGT), a traditional formula, is employed in the treatment of sore throat and cough and comprises Platycodonis Radix and Glycyrrhizae Radix et Rhizoma in the ratio 1 : 2. Our previous study demonstrated that JGT protected mice from S. aureus-induced acute lung injury (ALI).
