<p><b>A</b>: The levels of NF-κB in TNF-α stimulated HEK 293 cells. Values are presented as the mean ± SEM, <i>n</i> = 5 for each group. **<i>p</i> <0.05 <i>vs</i> the group that was treated with TNF-α in the absence of extracts and drugs, ^##<i>p</i> < 0.05 <i>vs</i> the Control group; <b>B</b>: The relative content of each marker ingredient in different organs. Zero content was expressed as red and largest content (100%) as green.
