Curcuma zedoaroides rhizomes have been used in Thai folk medicine as antidote and wound care for king cobra bite wound. The inhibitory effect of C. zedoaroides extract and its fractions on inflammation were detected by reduction of nitric oxide release using RAW264.7 cells. The improvement capabilities on wound healing were determined on fibroblast L929 cells proliferation and migration assays. The results showed that crude EtOH extract, CHCl3 and hexane fractions inhibited NO release with IC50 values of 14.0, 12.4 and 14.6 µg/ml, respectively. The CHCl3 and EtOAc fractions significantly increased L929 cells proliferation, enhanced fibroblast cells migration (100%) on day 3 and scavenged DPPH with IC50 of 40.9 and 7.2 µg/ml, respectively. Only the CHCl3 fraction showed marked effect against carrageenan-induced rat paw edema (IC50 = 272.4 mg/kg). From the present study, both in vitro and in vivo models support the traditional use of C. zedoaroides.
