The volatile aromatic substances from Cinnamomum camphora and C. japonicum among warm-temperate tree species were examined for the physiological and psychological effects on the human body. Each scent of the trees was provided to the test materials. And then their brain wave, pulse rate, aroma sensibility evaluation and POMS were measured as follows. To examine psychological effect of aroma of each tree species on human bodies, aroma sensibility evaluation and POMS were conducted. The result reveals that the aroma of the two tree species were interpreted in terms of comfort, naturalness and stimuli, and that C. camphora shows low level of satisfaction due to strong aroma while C. japonicum is more preferred due to its soft and fragrant aroma. As well, POMS was given to identify subjects' temporary emotional state. The result indicates that C. camphora has higher values in every item than C. japonicum, and that both tree species repress anxiety and depression and create vivacious feelings with higher values in [vivacity] and [anger-hostility] items than [tense-anxiety] and [distress-depression]. To examine the physiological effect of aroma of each tree species, aroma extracted from the two tree species were distributed, and the subjects' brain wave and impulse were measured. The result demonstrates that C. camphor has relaxing effect of increasing α-wave and reducing pulse, and that C. japonicum also has relaxing effect, but the effect is less than that of C. camphora as it reduces pulse though it slightly reduces α-wave. In addition, individual preferences for C. camphora vary as it has big individual deviations vary, but C. japonicum has similar level of preference as its variances are small. The natural and pleasant aroma of these two tree species seem to have tranquilizing effect in both the physiological and psychological aspects and are found to have positive effects of feeling refreshed, feeling enhanced, and so on. In conclusion, there is a sufficient possibility of developing these two aromatic warm-temperate tree species. Also, the importance of such difference between these two tree species lies in the fact that they can set standards for the utilization of warm-temperate forest in the future.
