Dose-dependent inhibition of LPS-mediated production of TNF-α-untreated and LPS-treated THP-1 cells by Saponaria officinalis (SO) and Inula helenium (IH) extracts. For each concentration treatment, the level of TNF-α release is represented as a percentage of the control set at 100%. The bar heights represent the values of means ± SD ( significant as compared to LPS alone) of three independent ELISA experiments carried out in triplicates.
