Sedative activity was assessed by determining the effect of the extract on length of diazepam-induced sleeping time.

Results: Results of the present study revealed that, the extract possess anti-inflammatory and sedative activities in the third hour.

Conclusion: The extract has been established to have analgesic effect, and in this study to have anti-inflammatory property with central sedative effect.
