Values are expressed as the mean ± standard error of the mean. ^ap < 0.05 compared with the control. ^bp < 0.05 compared with untreated control (AlCl₃). ^cp < 0.05 compared with the AlCl₃+TE+EO-treated group (25 mg/kg); ^dp < 0.05 compared with the AlCl₃+TE+EO-treated group (50 mg/kg). ^∗p < 0.05 comparing second retention with first retention by paired t-test. AlCl₃: aluminum chloride; TE+EO: turmeric extract and essential oil combination.
