Background: Anxiety is a serious disorder affecting the world population. The most widely prescribed medications for anxiety disorders are the Benzodiazepines; however, they have prominent side effects. Thus, interest in alternative medicine that affects the ‘mind’ is growing. Among medicinal plants, Urtica urens has been recommended for relief of anxiety in Morocco folk medicine.
Methods: The anxiolytic activity was evaluated with the adult mice by the elevated plus maze (EPM) and Open Field (OF) models of anxiety. The efficacy of the plant extract (100-600 mg/kg) was compared with the standard anxiolytic drug diazepam (1 mg/kg i.p.)
Results: In the EPM, aqueous extract at 400mg/kg showed an anxiolytic effect by increasing the time spent on open arms and the percentage of open arm entries compared to control group. In an open field test aqueous extract of U. urens (400 mg/kg) increased the central area crossing, the time spent and number of rearing in the center of arena.
Conclusions: These results provides support for anxiolytic activity of Urtica urens, in line with its medicinal traditional use, and may also suggest a better side-effect profile of Urtica urens relative to diazepam.
