- Fate and control of pathogenic and spoilage micro-organisms in orange blossom (Citrus aurantium) and rose flower (Rosa centifolia) hydrosols. [Journal Article]
- J Appl Microbiol 2016 Sep 12JA
- CONCLUSIONS: Pathogenic micro-organisms likely represent a low risk in rose flower and orange blossom hydrosol. However the oligotrophic character of hydrosols and the antimicrobial properties of their essential oils do not prevent microbiological spoilage by the naturally present microbiota.

This present study was carried out to investigate the likely mechanisms by which methyl jasmonate (MJ), 'an agent widely used in aromatherapy for neurological disorders, attenuates lipopolysaccharide (LPS)-induced memory deficits in mice. Mice were given intraperitoneal administration of LPS (250 µg/kg) alone or in combination with MJ (10-40 mg/kg), donepezil, DP (1 mg/kg), or vehicle for 7 successive days. Thereafter, memory was assessed using object recognition test (ORT). Acetylcholinesterase and myeloperoxidase activities were estimated in brain tissue homogenates. Brain levels of nitric oxide and markers of oxidative stress as well as histopathologic changes of the prefrontal cortex and cornu ammonis 1 (CA1) of the hippocampal region were also assessed. MJ (10-40 mg/kg) attenuated LPS-induced memory impairment in ORT. Moreover, the increased brain activities of acetylcholinesterase and myeloperoxidase enzymes were suppressed by MJ when compared with control (p < 0.05). Increased brain oxidative stress and nitric oxide levels in LPS-treated mice were significantly decreased by MJ. It offers protection against LPS-induced neuronal degeneration of the prefrontal cortex and CA1 of the hippocampus, suggesting neuroprotective effect. Taken together, these findings showed that MJ offers protection against LPS-induced memory deficits via mechanisms related to inhibition of acetylcholinesterase, myeloperoxidase, oxidative stress and neuronal degeneration.
- Comparing the effects of aromatherapy massage and inhalation aromatherapy on anxiety and pain in burn patients: A single-blind randomized clinical trial. [Journal Article]
- Burns 2016 Aug 26B
- CONCLUSIONS: The study results showed the positive effect of aromatherapy massage and inhalation aromatherapy compared with the control group in reducing both anxiety and pain of burn patients. Therefore, both interventions, which are inexpensive, and noninvasive nursing tasks can be proposed for alleviating anxiety and pain of burn patients.

- Effect of lavender essence inhalation on the level of anxiety and blood cortisol in candidates for open-heart surgery. [Journal Article]
- Iran J Nurs Midwifery Res 2016 Jul-Aug; 21(4):397-401IJ
- CONCLUSIONS: Results showed the positive effect of lavender essence on anxiety and blood cortisol level among the patients. Aromatherapy with lavender is suggested to be considered as a nursing intervention in clinical settings.
- Both lavender fleur oil and unscented oil aromatherapy reduce preoperative anxiety in breast surgery patients: a randomized trial. [Journal Article]
- J Clin Anesth 2016; 33:243-9JC
- CONCLUSIONS: Both LFO and UO aromatherapy treatments lowered anxiety before surgery despite no significant changes in vital signs. LFO treatment generated a slight but statistically significant increase in positive feelings compared with UO treatment. It is probable that the beneficial effect observed was due to both aromatherapy with LFO and a placebo effect related to the added attention given to the patients.
- De Novo Sequencing and Analysis of Lemongrass Transcriptome Provide First Insights into the Essential Oil Biosynthesis of Aromatic Grasses. [Journal Article]

Aromatic grasses of the genus Cymbopogon (Poaceae family) represent unique group of plants that produce diverse composition of monoterpene rich essential oils, which have great value in flavor, fragrance, cosmetic, and aromatherapy industries. Despite the commercial importance of these natural aromatic oils, their biosynthesis at the molecular level remains unexplored. As the first step toward understanding the essential oil biosynthesis, we performed de novo transcriptome assembly and analysis of C. flexuosus (lemongrass) by employing Illumina sequencing. Mining of transcriptome data and subsequent phylogenetic analysis led to identification of terpene synthases, pyrophosphatases, alcohol dehydrogenases, aldo-keto reductases, carotenoid cleavage dioxygenases, alcohol acetyltransferases, and aldehyde dehydrogenases, which are potentially involved in essential oil biosynthesis. Comparative essential oil profiling and mRNA expression analysis in three Cymbopogon species (C. flexuosus, aldehyde type; C. martinii, alcohol type; and C. winterianus, intermediate type) with varying essential oil composition indicated the involvement of identified candidate genes in the formation of alcohols, aldehydes, and acetates. Molecular modeling and docking further supported the role of identified protein sequences in aroma formation in Cymbopogon. Also, simple sequence repeats were found in the transcriptome with many linked to terpene pathway genes including the genes potentially involved in aroma biosynthesis. This work provides the first insights into the essential oil biosynthesis of aromatic grasses, and the identified candidate genes and markers can be a great resource for biotechnological and molecular breeding approaches to modulate the essential oil composition.
- Investigating the effect of rose essential oil in patients with primary dysmenorrhea. [Journal Article]
- Complement Ther Clin Pract 2016; 24:45-9CT
- CONCLUSIONS: The present study suggests that aromatherapy with rose essential oil, which is a nonpharmacologic treatment method, as an adjuvant to conventional treatment methods may be beneficial for pain relief in individuals with primary dysmenorrhea.

The genus Ocimum are used in cooking, however, their essential oils are utilized in traditional medicine as aromatherapy. The present study was carried out to investigate the chemical composition and systemic anti-inflammatory activity of the Ocimum basilicum essential oil (EOOB) and its major component estragole, as well as its possible mechanisms of action. The Ocimum basilicum essential oil was obtained by hydrodistillation and analyzed by GC-MS. The anti-inflammatory action was verified using acute and chronic in vivo tests as paw edema, peritonitis, and vascular permeability and granulomatous inflammation model. The anti-inflammatory mechanism of action was analyzed by the participation of histamine and arachidonic acid pathways. The chemical profile analysis identified fourteen components present in the essential oil, within them: estragole (60.96%). The in vivo test results show that treatment with EOOB (100 and 50 mg/kg) and estragole (60 and 30 mg/kg) significantly reduced paw edema induced by carrageenan and dextran. The smallest doses of EOOB (50 mg/kg) and estragole (30 mg/kg) showed efficacy in the reduction of paw edema induced by histamine and arachidonic acid, vascular permeability inhibition and leukocyte emigration in the peritoneal fluid. Theses doses were capable of reducing the chronic inflammatory process. The results observed between the EOOB and estragole demonstrate efficacy in anti-inflammatory activity, however, the essential oil is more efficacious in the acute and chronic anti-inflammatory action. This study confirms the therapeutic potential of this plant and reinforces the validity of its use in popular medicine.
