In indigenous.or folk m.dicine, Euphorbia hirta is.a very popular herb and us.d as.a palliative to treat various.ailm.nts.including intes.inal paras.tes. diarrhoea, vom.ting, am.ebic dys.ntery, as.hm., bronchitis. em.hys.m., coughs. kidney s.ones. m.ns.rual problem.0}etc. The objective of this.s.udy is.to evaluate the anxiolytic and s.dative-like effects.of the m.thanol extract from.the leaves.of Euphorbia hirta (Euphorbiaceae). m.thanolic extract of Euphorbia hirta was.evaluated for its.CNs.depres.ion effect us.ng m.ce behavioral m.dels.s.ch as. elevated plus.m.ze and hole board tes. for its.anxiolytic potential where hole cros. and pentobarbital-induced s.eeping tim. tes.s.were perform.d for its.s.dative properties. res.ectively. The tes. group received three different dos.s.of the m.HL (100 m./kg, 200 m./kg and 300 m./kg) orally. The pos.tive control group received diazepam.(1 m./kg) orally where the negative control group received dis.illed water (10 m./kg) orally. In elevated plus.m.ze tes., the extract exhibited s.gnificant (p d the num.er of open arm.entry and tim. s.ent in open arm.by m.ce com.ared to control group.
