Euphorbia hirta and Lactuca virosa are medicinal plants that have been used in the cure and treatment of various diseases and for health care. This study aims at evaluating the anti-inflammatory activities of the aqueous extracts of Euphorbia hirta and Lactuca virosa plants. Albumin and histamine induced inflammation in mice and xylene induced ear edema were used for the in-vivo anti-inflammatory studies. Erythrocyte membrane stabilization and inhibition of protein denaturation assays were used for the in-vitro anti-inflammatory studies. Combined doses of 100 mg/kg Euphorbia hirta and 50 mg/kg Lactuca virosa, 100 mg/kg Euphorbia hirta and 100 mg/kg Lactuca virosa, 100 mg/kg Lactuca virosa only and 10 mg/kg diclofenac significantly reduced inflamed paw in mice (P<0.05) compared to control in albumin and histamine induced inflammatory test. Combined doses of 50 mg/kg Euphorbia hirta and 100 mg/kg Lactuca virosa,100 mg/kg Euphorbia hirta, 100mg/kg Lactuca virosa significantly reduced xylene induced inflammation (P<0.001) compared to control. The extracts at 1 mg/ml, 2 mg/ml and 3 mg/ml significantly inhibited protein denaturation (P<0.001) and heat induced hemolysis of erythrocytes (P<0.0001). The plant extract of Euphorbia hirta and lactuca virosa possesses in-vivo and in-vivo anti-inflammatory effects.
