Background: Although the Ylang-Ylang aroma (YYA) has used as a general method for enhancing sedative effect, there was a little report on the efficacy of YYA on heart function using the electrocardiogram (EKG). Therefore, identifying of the effects of YYA on blood pressure (BP) and heart rate (HR) is important in order to demonstrate the effectiveness of YYA. The aim of this study was to investigate the effects of YYA on BP and HR in healthy men.
Conclusion: In the present results, YYA caused a reduction of HR and BP, and a relief of the arousal level in healthy men. The present results show a sedative effect of YYA, and this study provides some evidences for the usage of YYA in medicinal agent.

Background: This study provides further evidence for the impact of the aromas of plant
essential oils on aspects of cognition and mood in healthy participants.
Conclusion: Peppermint was found to enhance memory whereas ylang-ylang impaired it, and lengthened processing speed. In terms of subjective mood peppermint increased alertness and ylang-ylang decreased it, but significantly increased calmness. These results provide support for the contention that the aromas of essential oils can produce significant and idiosyncratic effects on both subjective and objective assessments of aspects of human behavior.

Background: Scientific evaluations of the effects of fragrances on humans are rather scarce. The aim of this investigation was to study the effects of ylang-ylang oil (Cananga odorata, Annonaceae) on human physiological parameters and self-evaluation.
Conclusion: The present investigation showed that ylang-ylang oil may be characterized by the concept of "harmonization" rather than relaxation/sedation. Compared to an odorless placebo, ylang-ylang oil caused significant decreases in blood pressure and pulse rate as well as significant increases of subjective attentiveness and alertness. Correlational analyses revealed that the observed effects are mainly due to a subjective odor experience.

Background: This review summarizes the effects of olfactory stimulation with grapefruit (limonene) and lavender oils on autonomic nerve activity and physiological function. Olfactory stimulation with the scent of grapefruit oil (GFO) increases the activity of sympathetic nerves that innervate white and brown adipose tissues, the adrenal glands, and the kidneys, decreases the activity of the gastric vagal nerve in rats and mice. This results in an increase in lipolysis, thermogenesis, and blood pressure, and a decrease in food intake.
Conclusion: These findings indicate that limonene...might be the active substance(s) in GFO...and are involved in mediating the GFO…--induced changes in nerve activity and physiological variables.

BACKGROUND: Essential oils have been used as an alternative and complementary treatment in medicine. Citrus fragrance has been used by aromatherapists for the treatment of anxiety symptoms. Based on this claim, the aim of present study was to investigate the effect of aromatherapy with essential oil of orange on child anxiety during dental treatment.
CONCLUSION: It seems that the use of aromatherapy with natural essential oil of orange could reduce salivary cortisol and pulse rate due to child anxiety state.

OBJECTIVES: The objective of this study was to evaluate the potential anxiolytic effect of sweet orange (Citrus sinensis) aroma in healthy volunteers submitted to an anxiogenic situation.
CONCLUSIONS: Although more studies are needed to find out the clinical relevance of aromatherapy for anxiety disorders, the present results indicate an acute anxiolytic activity of sweet orange aroma, giving some scientific support to its use as a tranquilizer by aromatherapists.
