Anti-inflammatory and gastroprotective activities of the aqueous extract of Micromeria fruticosa (L.) Druce ssp Serpyllifolia in mice

Micromeria fruticosa is used widely in many mediterranean regions for various inflammatory conditions. the aim of this work was to assess the anti-inflammatory and gastroprotective activities of the aqueous extract of micromeria fruticosa. the aqueous extract of micromeria fruticosa was tested orally in mice at doses of 50, 100 and 200 mg/kg in carrageenan-induced paw edema, vascular permeability, myeloperoxidase activity (mpo) and indomethacin-induced gastric ulceration. in the paw edema model, the extract at dose of 200 mg/ kg, exhibited a significant anti-inflammatory effect, while the extract at 100 and 200 mg/kg reduced significantly the vascular permeability and mpo activity in a dose dependant manner. oral pretreatment of the aqueous extract reduced significantly the development of gastric lesions induced by indomethacin at dose of 200 mg/kg only. results suggest that the aqueous extract of micromeria fruticosa has both anti-inflammatory as well as, gastroprotective activities. thus it could be used as an alternative or supplementary herbal remedy for the treatment of inflammatory diseases especially when combined with strong antiinflammatory medications that have ulcerogenic side effects such as nsaids.
