The effects of the odor of jasmine tea on
autonomic nerve activity and mood states
in a total of 24 healthy volunteers. R–R
intervals and the POMS test were measured
before and after inhalation of the odors for
5 min. Both jasmine tea and lavender odors
at perceived similar intensity caused
significant decreases in heart rate and
significant increases in spectral integrated
values at high-frequency component in
comparison with the control (P < 0.05). In
the POMS tests, these odors produced calm
and vigorous mood states. Thus, the low
intensity of jasmine tea odor has sedative
effects on both autonomic nerve activity
and mood states, and (R)-(–)-linalool, one of
its components, can mimic these effects (43).
