Cell viability after treatment with aCE. The L929 cells were treated with aCE (33.3 to 0.26 mg/mL, final concentrations) of Cinnamomum cassia (A), Cinnamomum zeylanicum (B), and Cinnamomum loureiroi (C) for 24 h, and viability was determined using the redox reagent, Alamar Blue. Experiments were performed thrice, and the data represent mean values. aCE, aqueous cinnamon extract. The U937 cells were treated with aCE (33.3 to 0.26 mg/mL, final concentrations) of Cinnamomum cassia (D), Cinnamomum zeylanicum (E), and Cinnamomum loureiroi (F) for 24 h, and viability was determined using the redox reagent, Alamar Blue. Experiments were performed thrice and mean of the data was plotted. aCE, aqueous cinnamon extract
