Young Yum pill inhibits inflammatory mediators and nuclear factor-kappa B signaling in lipopolysaccharide-stimulated RAW 264.7 macrophages.

Objective: To investigate the effect of Young Yum pill (YYP) on inflammatory mediators in cultured RAW 264.7 cells and elucidate the nuclear factor-kappa B (NF-κB)-related mechanism behind the action.

Methods: YYP was extracted with 95% ethanol Lipopolysaccharide (LPS)-stimulated RAW 264.
