“…However, the evidence from the current study and several previous studies 32,33 did not indicate that lavender aromatherapy interfered with HPA axis activation and cortisol release because no lavender-specific effects on post-stress cortisol levels were observed. On the basis of lavender effects on ANS evident from changes in respiration and CgA, lavender may affect some ANS aspects.…”

Objective: Aromas may improve physiologic and cognitive function after stress, but associated mechanisms remain unknown. This study evaluated the effects of lavender aroma, which is commonly used for stress reduction, on physiologic and cognitive functions. The contribution of pharmacologic, hedonic, and expectancyrelated mechanisms of the aromatherapy effects was evaluated. Methods: Ninety-two healthy adults (mean age, 58.0 years; 79.3% women) were randomly assigned to three aroma groups (lavender, perceptible placebo [coconut], and nonperceptible placebo [water] and to two prime subgroups (primed, with a suggestion of inhaling a powerful stress-reducing aroma, or no prime). Participants' performance on a battery of cognitive tests, physiologic responses, and subjective stress were evaluated at baseline and after exposure to a stress battery during which aromatherapy was present. Participants also rated the intensity and pleasantness of their assigned aroma. Results: Pharmacologic effects of lavender but not placebo aromas significantly benefited post-stress performance on the working memory task (F (2, 86) = 5.41; p = 0.006). Increased expectancy due to positive prime, regardless of aroma type, facilitated post-stress performance on the processing speed task (F (1, 87) = 8.31; p = 0.005). Aroma hedonics (pleasantness and intensity) played a role in the beneficial lavender effect on working memory and physiologic function. Conclusions: The observable aroma effects were produced by a combination of mechanisms involving aromaspecific pharmacologic properties, aroma hedonic properties, and participant expectations. In the future, each of these mechanisms could be manipulated to produce optimal functioning.

“…16 A recent finding from the author's laboratory further demonstrated that salivary CgA levels in the late-luteal phase significantly increased among women with severe premenstrual emotional symptoms, while salivary cortisol showed no menstrual-cyclic changes. 17 In contrast, stress-reduction interventions, such as aromatherapy with lavender essential oil, 14 exposure to negative air ions, 13 and laughter while watching a comedy video, 18 have decreased salivary CgA levels. Saliva testing is a novel device with the advantage of quick, painless, noninvasive, and relatively nonstressful sampling.…”

“…11 Salivary CgA, thus, has been proposed as a surrogate marker of sympathetic nervous system activity. 12 A series of studies has shown that compared with salivary cortisol, salivary CgA increases more rapidly and more sensitively to psychological stressors induced by activities such as public speaking, 12 word-processing and arithmetic tasks, 13,14 academic examinations, 15 and venipuncture in hospitalized children. 16 A recent finding from the author's laboratory further demonstrated that salivary CgA levels in the late-luteal phase significantly increased among women with severe premenstrual emotional symptoms, while salivary cortisol showed no menstrual-cyclic changes.…”

Objective: This study investigated the soothing effects of fragrance from yuzu, a Japanese citrus fruit (Citrus junos Sieb. ex Tanaka), with salivary chromogranin A (CgA) used as an endocrinologic stress marker reflecting sympathetic nervous system activity. Methods: Twenty healthy women (mean age, 20.5 -0.1 years) participated in a randomized, controlled, crossover study. Participants were examined on two separate occasions-once using the yuzu scent and once using unscented water as a control-in the follicular phase. This experiment measured salivary CgA and the Profile of Mood States (POMS) as a psychological index before and after the aromatic stimulation. Results: Ten-minute inhalation of the yuzu scent significantly decreased salivary CgA. At 30 minutes after the inhalation period, the salivary CgA level further decreased. In addition, POMS revealed that inhalation of the aromatic yuzu oil significantly decreased total mood disturbance, a global measure of affective state, as well as four subscores of emotional symptoms (tension-anxiety, depression-dejection, anger-hostility, and confusion), as long as 30 minutes after the olfactory stimulation. Conclusions: Yuzu's aromatic effects may alleviate negative emotional stress, which, at least in part, would contribute to the suppression of sympathetic nervous system activity.

Objective: Ginger has always been known as one of the most famous medicinal herbs in eastern Asia (China and India). In this study we examined the effects of antidepressants-like activity of Ginger on the protection of central nervous system against oxidative damages. Material and Methods: Male Wistar rats (n=30) were allocated into three groups, control (n=10) and test groups (n=20) that subdivided into groups of 2 that had been exposed to 50 Hz electromagnetic fields (EMFs) for 8 weeks, one of the test groups received Ginger rhizome powder (1.5 g/kg/day. body weight) for 8 weeks as well. In the second and eighth weeks, we used forced swimming test in order to evaluate the antidepressant effect of Ginger powder on the rats exposed to EMF. Results: In the second week results revealed EMF exposure increase immobility but decrease loco-motor function of swimming and climbing in comparison to control group (P < 0.05) whereas at the end of 8th week, rats that had been fed with Ginger powder (1.5 g g/kg/day .body weight) showed decrease in immobility score and increase in swimming (P < 0.001), but not in climbing scores significantly. (P =0.18). Conclusion: Ginger powder could act as serotoninergic antidepressant medicine in order to decrease depression presentation in exposed subjects to EMF.
