Sedative effects of the jasmine tea odor and (R)-(−)-linalool, one of its major odor components, on autonomic nerve activity and mood states

Abstract

We investigated the effects of the odor of jasmine tea on autonomic nerve activity and mood states in a total of 24 healthy volunteers. We used the odor of jasmine tea at the lowest concentration that could be detected by each subject but that did not elicit any psychological effects. 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. We also examined the effects of (R)-(-)-linalool, one of its major odor components, at the same concentration as in the tea, and (S)-(+)-linalool. Only (R)-(-)-linalool elicited a significant decrease in heart rate (P < 0.05) and an increase in high-frequency component in comparison with the controls, and 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.

Sedative effect of central administration ofCoriandrum sativumessential oil and its major component linalool in neonatal chicks

“…These results suggest that linalool had a dose-dependent sedative effect in neonatal chicks as observed for CEO (8.6 and 86 mg) and diazepam (17.5 mg). It has been reported that i.p administration or inhalation of linalool had a sedative effect in rodents and humans (Kuroda et al 2005;Linck et al 2009), however, until now, there are no reports with similar behavioural effects in avian species.…”

Effects of CH-19 Sweet, a Non-Pungent Cultivar of Red Pepper, on Sympathetic Nervous Activity, Body Temperature, Heart Rate, and Blood Pressure in Humans

“…Power spectral analysis has been used to detect changes in autonomic nervous activity in response to the intake of foods or the inhalation of odors in humans. [14][15][16][17] Details of the power spectral analysis procedure have been fully described by Moritani et al 18,19) A power spectral analysis by fast Fourier transformation was performed on consecutive 256-s time series of the R-R interval data obtained during the test. To evaluate the autonomic nervous system activity of each subject in the present study, we analyzed both low-frequency (LFC, 0.035-0.15 Hz) and high-frequency (HFC, 0.15-0.5 Hz) components, the latter being the respiration-linked component.…”

Effects of Olfactory Stimulation from the Fragrance of the Japanese Citrus Fruit Yuzu (Citrus junos Sieb. ex Tanaka) on Mood States and Salivary Chromogranin A as an Endocrinologic Stress Marker

“…31 As a global measure of affective state, a total mood disturbance (TMD) score was also calculated, with higher scores indicating more mood disturbance, by adding the Tscores on the six subscales; vigor was negatively weighted. 17,32 Referring to a study by Kuroda and colleagues 33 and the authors' recent aroma research, 26 to investigate the effect of yuzu aroma on mood states, changes in the POMS scores of the yuzu and control trials were compared before and 30 minutes after the aroma stimulation.…”
