  • Title: Anxiolytic effects of Echium amoenum on the elevated plus-maze model of anxiety in mice.
    Author: Rabbani M, Sajjadi SE, Vaseghi G, Jafarian A.
    Journal: Fitoterapia; 2004 Jul; 75(5):457-64. PubMed ID: 15261383.
    Abstract:
    The ethanolic extract of Echium amoenum flowers at the dose of 50 mg/kg increased the percentage of time-spent and the percentage of arm entries in the open arms of the elevated plus-maze (EPM) and decreased the percentage of time-spent in the closed arms of EPM. Moreover, it prolonged the ketamine-induced latency to sleep but had no significant effects on total sleeping time induced by ketamine. Also, the locomotor activity was affected but not to the same extent as observed for diazepam. These results suggested that the extract of E. amoenum seems to possess anxiolytic effect with lower sedative activity than that of diazepam.
