The chemical compositions of FSCR were analysed by UPLC-PDA-MS. A PID model induced by phenol mucilage was successfully established in rats. The effects of FSCR on rats with PID were studied. FSCR attenuated pelvic inflammation and prevented fibrosis. The ERK1/2 and Smad2/3 signalling pathways may be involved in the effects of FSCR.
