Effects of Inhaled the Cyperi rhizoma and Perillae herba Essential Oil on Emotional States, Autonomic Nervous System and Salivary Biomarker
Abstract: It is well-known that odor has a good influence on a human mind and body. In this study, we investigated the effect of the essential oil inhalation of Cyperi rhizoma and Perillae herba which were main aromatic herbs ingredient of the Kososan, to psychological condition, autonomic nerve activity and salivary biomarker. In addition, we examined influence by the favorite difference in odor. 25 healthy female volunteers (control group: 5 people; Cyperi rhizoma group: 10 people; Perillae herba group: 10 people) were examined. POMS was examined at PRE and POST the experiment. Pulse analyser was examined and saliva samples were collected before the inhalation, just after the inhalation, 10 minutes and 20 minutes later, respectively. Saliva samples analyzed for levels of α-amylase and cortisol. At the examination for POMS after the experiment, the preference for the odor was confirmed. About both Cyperi rhizoma and Perillae herba, by the essential oil inhalation, mental stability and relaxation effect were provided in psychological and psysiological evaluation. In the “like” group, relaxation was greater than “unlike” group. However, about Cyperi rhizoma, the stress was relaxed regardless of the favorite difference in odor, and a physical relaxation effect was shown. In addition, about the autonomic nerve activity, the parasympathetic nerve was not activated, and it was suggested that it was made and stabilized the balance of the autonomic nerve.
