The murine model of OVA-induced immediate allergic reaction was used to evaluate the effectiveness of intraperitoneal sub-acute treatment with the leaf hydroalcoholic extract of Cissampelos sympodialis (AFL) in the anaphylactic shock reaction, IgE production and the background proliferative response. BALB/c mice treated with AFL ranging from 200 to 400 mg/kg/day for 5 days before and during OVA-sensitization strongly reduced the animal death and promoted reduction in total and OVA-specific serum IgE level. Spleen cells from AFL-treated sensitized animals showed a decreased proliferative background response when compared with non-sensitized animals. These results demonstrated that sub-acute intraperitoneal treatment with Cissampelos sympodialis extract has an anti-allergic effect.
