Inhibitory effect of Hwang lyun tang water extract on inflammatory mediators

The purpose of this study was to investigate the anti-inflammatory effects of extract from Hwang lyun tang (HLT) on the THP-1 cell and HMC-1 cell. To evaluate of anti-inflammatory of HLT, we examined cytokines production in lipopolysacchride (LPS)-induced THP-1 cell and A23187, PMA-induced HMC-1 cell. Extract of HLT inhibit LPS-induced interleukin (IL)-8 production in human monocyte THP-1 cells. Extract of HLT inhibit A23187, PMA-induced IL-8, tumor necrosis factor-$\alpha$ (INF-$\alpha$) production in HMC-1 cells. HLT down-regulated LPS-induced IL-8 production and A23187, PMA-induced IL-8, TNF-$\alpha$ production, which may be provide a clinical basis for anti-inflammatory properities of HLT.
