Anxiety and depression are the most common mental illnesses. Oxidative stress is one of the causes of anxiety and depression. Lepidium sativum has anti-inflammatory and antioxidant properties. The aim of this study was to investigate the effect of aqueous extract of Lepidium sativum on anxiety-like and depression-like behaviors in adult male mice. In this study, male mice weighing 30-35 g were used. First, the tested animals were treated with aqueous extract of Lepidium sativum at doses of 200, 400 and 600 mg/kg for 2 weeks. At the end of the treatment period, the levels of anxiety and depression were assessed by an elevated plus maze (EPM) and forced swimming test, respectively. No significant changes were observed in any of the groups receiving Lepidium sativum extract in the time spent in the open arm, the number of entrances to the open arm and motor activity. The results of forced swimming test showed that in animals receiving Lepidium sativum extract at doses of 400 and 600 mg/kg, swimming time and immobility time were significantly increased and decreased compared to the control group, respectively (p < 0.01). The results of this study showed the modulatory effects of Lepidium sativum extract on depressive-like behaviors, but this extract had no significant effects on anxiety-like behaviors.
