Figure 1.

Boxplots of the percentage of neutrophils (a) and monocytes (b) producing ROS (N_ROS [%] and M_ROS [%], resp.) and a mean fluorescent intensity (MFI) of these cells ((c) and (d)) stimulated with PMA or E. coli after their exposition to the extract (0.1 and 0.25 mg/mL) versus control (without the extract) for PMA and E. coli stimuli. Middle point: median; box: interquartile range; whisker: range (excluding outliers). Significance levels *P < 0.05, **P < 0.01, and ***P < 0.001 assessed by Wilcoxon's test are indicated by asterisks.
