This study was produced to examine the effects of moxibution that had been played a role of traditional oriental medical treatment on disease. We used LPS and INF-gamma in RAW 264.7 cell line to produce Nitric Oxide(NO). And results was that Moxi tar decreased NO in activated RAW 264.7 cell by LPS and INF-gamma significantly, which was decreasing Nitric Oxide Synthase. So we proposed that Moxi tar had anti-inflammation and anti-cytotoxity in RAW 264.7 cell by decreasing Nitric Oxide Synthase.
