<i>Hypericum triquetrifolium</i>—Derived Factors Downregulate the Production Levels of LPS-Induced Nitric Oxide and Tumor Necrosis Factor-<i>α</i> in THP-1 Cells

<table>Dose-dependent inhibition of LPS-mediated production of TNF-<i>α</i> by <i>H. triquetrifolium</i> extracts. For each concentration treatment, the level of TNF-<i>α</i> release is represented as a percentage of the control set at 100%. The bar heights represent the values of mean ± SD (*<i>P</i> &lt; .05 significant as compared with LPS alone) of three independent ELISA experiments carried out in triplicate.</table>
