Descrição
Resumo:Oenothera rosea L' Hér. ex Ait. (Onagraceae) is commonly known as hierba del golpe. It is used in Mexican Folk Medicine to treat inflammatory, renal and bacterial diseases. The aim of this study was to evaluate the anti-inflammatory activity of aqueous and methanolic extracts of this plant. Aqueous extract at a dose of 500 mg/kg body weight (b.wt.) and methanolic extract (100 mg/kg b.wt.) of Oenothera rosea were evaluated for anti-inflammatory activity using the cotton pellet-induced granulomaformation model in rat and histological techniques. Both extracts produced a significant decrease of the inflammatory process in relation with the control groups (p<0.05). The anti-inflammatory effect of methanolic extract was similar to the effect of indomethacin. This data was supported by the histological results. No extracts produced gastrointestinal damage. The LD50 of aqueous and methanol extracts, was higher than 40 and 8 g/kg, respectively. These results suggest that both extracts of Oenothera rosea induced anti-inflammatory activity and it was considered not toxic.
