The current study was designed to identify the histopathplogical effects of the ethanolic extract of saffron flowers on the stomach and small intestine of female adult mouse at the doses of 25, 50 mg / kg of body weight (b.w.) for the periods 15, 30 days and once a day. Behavioral changes were include rapid movement of the animals, a simple lack of appetite for water and food, excitation, hyperactivity, hostility, weakness and convulsions in the movement of mice.

At the dose of 50 mg/kg b.w. for the  above periods, acute lymphocyte and neutrophils infiltration in mucosa and sub mucosa were observed, as well as sever degeneration in their cells, coagulative necrosis was also observed in the entire  cells of the lining of the small intestine.
