Alteration of Neutrophil Reactive Oxygen Species Production by Extracts of Devil’s Claw (Harpagophytum)

Figure 4

Luminol-detected total ROS production by neutrophils stimulated with (a) PBS or (b) PMA (25 nM) in the presence of PBS, ethanol, harpagoside (0.5 μg/mL), and verbascoside (0.5 μg/mL) (). Error bars: 95% CI. All sample results were compared by Wilcoxon two related samples tests.
