Effect of chamomile decoction extract (CDE) on superoxide anion production by human neutrophils using cytochrome c reduction assay. Cells (1 × 106) were incubated in the presence or not of different CDE concentrations and stimulated with PMA (100 ng/mL) or fMLF (0.1 μM). Cytochrome c reduction was measured at 550 nm in a spectrophotometer for 10 min (Data are presented as means ± S.E.M. of five independent experiments, *p < 0.05)
