... xposed to phenol. Methods: In this study, 54 Wistar rats were used in terms of a 3×3 factorial design with 3 levels of Hypericum perforatum extract (0, 250 and 500 mg/kg.bw) and 3 levels of phenol (0, 100 and 200 mg/kg.bw). Rats received the extract and phenol every other day via gavage method for periods of 15 and 30 days, respectively. Thirty min after each gavage, a behavior test was performed by using the open field and elevated plus-maze. Recuperative effects of Hypericum perforatum were assessed within short (first 15 days) and long (second 15 days) periods. Results: The statistic findings indicated that there were no significant differences between behavior tests with respect to the treatments (P> 0.05). Conclusion: The study results proposed that the used levels of Hypericum Perforarum extract did not show any significant effects on reduction of anxious and depressant behaviors in phenol exposed Wistar rats.
