Fig. 1. Effect of cinnamaldehyde on (a) the systolic blood pressure and (b) the diastolic blood pressure. Results are expressed as means ± SEMs, with n = 6. Data were analyzed by using the two-way ANOVA, followed by Bonferroni post tests. ^aP < 0.05, ^bP < 0.01, and ^cP < 0.001 as compared to day 0; ^dP < 0.05, ^eP < 0.01, ^fP < 0.001 as compared to week 3. CA-20 = cinnamaldehyde at 20 mg/kg/day; CA-30 = cinnamaldehyde at 30 mg/kg/day; CA-40 = cinnamaldehyde at 40 mg/kg/day.

SEMs, standard errors of the mean; ANOVA, analysis of variance.
