Sedative effects of different combinations of B, Y, P, and A herbs. The performances of mice treated with saline vehicle (Veh), diazepam (DZ), and different single-herb or multiherb extracts were assessed with respect to sedative effect using the hole-board test, where reduced head-dips represented a sedative effect. Data are expressed in mean ± SD of the number of head-dips. ^∗(p < 0.05), ^∗∗(p < 0.01), or ^∗∗∗(p < 0.001) indicates significant difference from Veh group based on one-way ANOVA test followed by Newman-Keuls test.
