Autonomic Nervous Sedative Effect
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)
