The purpose of this study was to observe the effects of aroma treatment on some stress related hormones to obtain the basic data for prevention of stress-related disease. On November 18, 2006, 37 healthy soldiers for the subject of investigation were divided into 4 groups. The four groups included aroma inhalation, aroma massage, regular oil massage and the control group that did not have any treatment. The effect of each treatment on the blood levels of ACTH and cortisol and blood pressure, pulse rate was observed. The results of this study: 1. At 40 minutes after the test, all the test groups except the control showed a tendency to elevate in blood pressure, especially the aroma massage group was higher in systolic (p<0.05) or diastolic blood pressure (p<0.01). And in the massage group, the systolic pressure was higher than the control (p<0.05). 2. After 20 or 40 minutes, all the groups except the control showed significantly decreased blood levels of ACTH (p<0.01). Furthermore, the aroma inhalation group showed the highest decreasing levels of ACTH among all groups (p<0.001). 3. Cortisol was significantly reduced in the all test groups but the control group (p<0.01) 20 minutes after the test. Cortisol continuously decreased in the aroma inhalation group (p<0.01) and massage group (p<0.05) 40 minutes after the test. The highest decrease of cortisol in the blood was shown in the aroma inhalation group. These results suggested that aroma inhalation and physical treatment such as massage might reduce the initial stress. To improve health science and alternative medical treatment, aroma inhalation is considered to be the meaningful method of treatment.
