Effect of chamomile on NO production in the culture medium of RAW 264.7 macrophages (A) time-dependent effect using 1 μg/mL LPS in the absence and presence of 10 μg/mL chamomile for indicated times. (B) dose-dependent effect using 1μg/mL LPS for 16 h in the presence and absence of chamomile at indicated doses. L-NMMA (1 mM), a non-selective inhibitor of all NOS isoforms was used as positive control. Bars represent mean ± SEM of at least 3 independent experiments each performed in triplicate, **P<0.001 (ANOVA) compared to LPS challenge group. Details are described in ‘Materials and methods’ section.
