Investigation of Immunomodulatory Potential of Hydro-Alcoholic Extracts of Euphorbia neriifolia Linn. and Hibiscus rosa sinensis Linn.

The assesement of immunomodulatory activity of hydro-alcoholic extracts of dried leaves of Euphorbia neriifolia Linn. (100, 200 and 400 mg/kg, p.o.) and dried flowers of Hibiscus rosa sinensis Linn. (75, 150 and 300 mg/kg, p.o.) were done by carbon clearance method, haemagglutination antibody titre method and footpad swelling method on wistar albino rats. Results of present studies suggest that the hydro-alcoholic extract of Euphorbia neriifolia Linn. was found to be more efficacious action on immune components on animals than hydro-alcoholic extract of Hibiscus rosa sinensis Linn. in dose dependent manner when compared with control group.
