The second group as a stress group received immobilization stress four hours for three days. Third group as stress plus peppermint oil group received stress in addition to administration of 27 mg/kg peppermint oil intraperitoneally before stress. After three days of treatment, food intake and body weight were measured. Based on food intake, there were statistical differences between control and stress groups (P=0.001), stress and stress plus peppermint oil (P=0.001), control and stress plus peppermint oil (P=0.025). Based on body weight, there were statistical differences in stress and stress+ peppermint oil groups before and after experiment (P<05). This study showed that the level of food intake and body weight in stress group after three days compared to the control group was decreased. Administration of peppermint oil, improved food intake and weight gain after chronic stress immobilization.
