In indigenous or folk medicine, Euphorbia hirta is a very popular herb and used as a palliative to treat various ailments including intestinal parasites, diarrhoea, vomiting, amoebic dysentery, asthma, bronchitis, emphysema, coughs, kidney stones, menstrual problems etc. The objective of this study is to evaluate the anxiolytic and sedative-like effects of the methanol extract from the leaves of Euphorbia hirta (Euphorbiaceae). Methanolic extract of Euphorbia hirta was evaluated for its CNS depression effect using mice behavioral models such as, elevated plus maze and hole board test for its anxiolytic potential where hole cross and pentobarbital-induced sleeping time tests were performed for its sedative properties, respectively. The test group received three different doses of the MEHL (100 mg/kg, 200 mg/kg and 300 mg/kg) orally. The positive control group received diazepam (1 mg/kg) orally where the negative control group received distilled water (10 ml/kg) orally. In elevated plus maze test, the extract exhibited significant (p d the number of open arm entry and time spent in open arm by mice compared to control group. In addition, the number of head dips and hole crosses significantly (p < 0.05) decreased by mice in hole board and hole cross tests respectively, compared to control group. Moreover, mice treated with MEHL significantly decrease the onset of sleep and increase the duration of sleep in pentobarbital-induced sleeping time test in mice compared to control group. The data obtained from the present study clearly demonstrate that the methanolic extract of Euphorbia hirta has potential anxiolytic and sedative-like activity in the animal behavioral models. And the findings represent a rational explanation for its use in traditional medicine for the management of neurological disorder.
