Effects of agarwood essential oil (AEO) on restraint stress-induced depression as assessed by the tail suspension (TS) test. All mice except for the naive group received 10 days restraint stress, and immobility was recorded during a 4 min test period. Each value represents mean ± SEM with n = 12, ^## p < 0.01 vs. the naive group, ** p < 0.01 vs. the stressed group.
