In this study, we analyzed the anti-oxidative and anti-inflammatory activities of seven medicinal herbs. All extracts of the tested herbs, Euryale ferox Salisbury, Echinops setifer Iljin, Amomum cardamomum Linne, Tetrapanax papyriferus, Illicium verum Hook. f., Typha orientalis Presl, and Piper longum Linne, exhibited potent anti-oxidative activity as confirmed by DPPH radical scavenging capacity. Lipopolysaccharide (LPS) induced nitric oxide (NO) production, in the RAW 264.7 cell line, was also ameliorated by all extracts' treatments in a dose dependent manner. NO suppressive activity originated from the inhibition of inducible nitric oxide synthase (iNOS) protein expression by the extracts. Three extracts, E. ferox S., I. verum Hook. f., and P. longum L., possessed suppressive activity against, not only iNOS, but also cycloxygenase 2 (COX-2) protein expression. These three extracts may then serve as potential candidates for non steroidal analgesic inflammation drugs (NSAIDs). Furthermore, all extracts induced anti-oxidative enzyme, heme oxygenase 1, protein expression. Taken together, these results provide an important new insight into the fact that various medicinal herbs possess potent anti- oxidative and anti-inflammatory activities and might be utilized as promising agents in the field of health products. Further studies for the identification of the active compounds from medicinal herbs are clearly needed.
