Effects of chamomile extracts on the viability of human epithelial Caco2 cells. Caco2 cells were incubated in the absence (ctrl) or in the presence of increasing concentrations (100–500 µg/mL) of chamomile extracts. After 24 h incubation, cells were harvested, and viability was assessed by MTT assay. Values are reported as percentage of control (ctrl) set to 100%. Data represent the mean ± SEM of at least three independent experiments, each performed in quintuplicate. * p < 0.05 and ** p < 0.001 vs. ctrl.
