%X This study was conducted to clarify the effect of eucalyptus essential  oil mixed with milk casein peptide food for human physiological  relaxation. Fifteen male university students (21.2 ± 0.9 yr)  participated in study as subjects. The subjects were given one of two  types of experimental drink (peptide + eucalyptus flavor (Pep + EF), and  peptide + grapefruit·orange flavor (Pep + G·O), each flavor contains  natural essential oil). We measured the change in salivary cortisol  concentration and POMS scores before and two hours after taking  experimental drink. The results of a Type A behavior pattern test were  used to classify subjects. The concentration of salivary cortisol  decreased significantly two hours after taking Pep + EF. And Type B  showed bigger change than Type A. In conclusion, the results show that  eucalyptus essential oil has the effect of relaxation, and that the  effects on Type A and Type B are different.
