The extract enhanced the phagocytic function and phagocytic index and blocked the immunosuppressive effect produced by dexamethasone. The alcoholic extract was without effect. These results suggest that aqueous extract of binweed has immunostimulant effects. Keywords: date palm;immune cells;rabbits;Binweed;alcholic;Saudi Arabia
