New herbal formula (NHF) is the ethanol extract mixture of Puerariae radix, Artemisia capillaries and Perilla frutescens. We have investigated the effects on anti-inflammation by NHF and attempted acetic acid induced writhing to verify the analgesic effect. Macrophages and chondrocytes were obtained from mouse and rabbit. Inflammation was induced by interleukin-1, tumor necrosis factor-α, interferon-γ, and lipopolysaccharide. NHF showed strong inhibitory efficacy against cytokine-induced proteoglycan degradation, PGE 2 production, NO production, and MMP-9 expression in rabbit articular chondrocyte. In the writhing test, NHF exhibited a dose-dependent inhibition of writhing. Futhermore, NHF increased the activity of SOD. NHF have anti-inflammatory and analgesic activities, and could be a good herbal medicine candidate for curing of osteoarthritis.
