Immunological studies on the aerial roots of the Indian banyan

Abstract

The aqueous extract of the aerial roots the Indian Banyan, Ficus benghalensis L. (Family: Moraceae) was evaluated for its effect on both specific and non-specific immunity. This extract exhibited a significant increase in percentage phagocytosis by human neutrophils in the in vitro tests. It exhibited promising immunostimulant activity at doses of 50, 100, 200 and 400 mg/kg body weight in SRBC induced hypersensitivity reaction and hemagglutination reaction in rats. The aqueous extract was found to stimulate the cell mediated and antibody mediated immune responses.
