ObjectiveThis study aimed to determine the effects of aromatherapy use on cognitive function, anxiety, and sleep quality in the elderly with diabetes. MethodsThe study was conducted with 63 participants aged 65 and over. Participants were randomly divided into three groups: lavender, rosemary and control groups. The intervention continued for four weeks. Data was collected using the Blessed Orientation Concentration Test, State-Trait Anxiety Scale, and Pittsburgh Sleep Quality Scale. Data were analyzed using One-Way ANOVA, Mann-Whitney U/Kruskal-Wallis, Wilcoxon and Friedman tests. ResultsIn both intervention groups, the 4th week scores of cognitive functions, anxiety, and sleep quality after aromatherapy were significant compared to the baseline scores. In the control group, state anxiety scores were significantly higher in the 2nd and 4th weeks compared to the initial scores. ConclusionsInhaling lavender and rosemary has been observed to improve cognitive function and sleep quality and reduce anxiety levels. The effects of the essential oils used in the research were evaluated over four weeks. It is thought that studying for a longer period and with more samples would be beneficial. There is a need for studies examining its effects, especially in the elderly with diabetes.

Effect of lavender and rosemary aromatherapy on test anxiety in chiropractic students.

Test anxiety is a debilitating disorder that can impair cognitive performance and affect academic success. Aromatherapy is commonly used for relaxation therapy. The primary aim of the study was to determine if nasal inhaler aromatherapy, utilizing a blend of rosemary and lavender essential oils, could be a useful strategy to reduce testing anxiety in students. This study recruited first trimester chiropractic students enrolled in both Neuroanatomy I and Biochemistry I. A randomized crossover design was utilized over 2 study days during final exams, with a 2-day wash-out period. Participants were randomly assigned into groups based on results of test anxiety analysis. On each day, students were given a nasal inhaler with either an aromatherapy blend of lavender and rosemary essential oils or distilled water as the control. Students completed pretest surveys and posttest surveys to rate their anxiety levels. Paired sample t-tests were performed to determine group differences in test anxiety. Both intention-to-treat and per-protocol analyses were conducted. Forty-five students were randomly assigned into the study, whereas only 38 completed per-protocol. Between group comparisons showed no statistically significant difference between change in anxiety scores between aromatherapy and control for both intention-to-treat (p =.10) and per-protocol (p =.07). Use of personal inhalers and aromatherapy diffusers were not shown to reduce test anxiety in a chiropractic population under high-stakes examination. Other options should be explored for future research.

The Effect of Lavender on Anxiety and Hemodynamic Status Before Septorhinoplasy and Rhinoplasty

PurposeAnxiety is one of the most common problems before surgery and surgery of the nose is one of the most concerning and challenging surgeries among the plastic surgeries. The aim of this research is to consider the impact of lavender fragrance on anxiety and hemodynamics status before the septorhinoplasty and rhinoplasty. DesignParallel randomized control trial. MethodsThis research was done by testing thirty-four candidates who were about to have the surgery in two groups of lavender (intervention) and control. The anxiety before and after surgery was examined by the Speilberger State Anxiety Inventory questionnaire and the hemodynamics status. For the analysis, the T- Test, Mann Whitney Test and the χ2 Test were used. FindingsThe demographic features of the two groups were similar. Anxiety after the experiment was meaningful. The obvious anxiety in the lavender category was 25.8% and the controlled group had that decreased to 1.8%. The latent anxiety was reduced by 24.3% in the lavender group and increased by 8% in the controlled group. The systolic, diastolic and the heart rate after the intervention was less in the lavender group. ConclusionsDue to the ease of the inhalation of lavender and the lack of any report for the existence of any kind of side-effects for the prevention of anxiety during nose surgeries, it can be suggested that this approach can be effective for the controlling of the consistency of the patients’ hemodynamics.

Preeclampsia is still a pregnancy complication that causes the third-highest maternal mortality in Indonesia. The focus of conservative care is to maintain blood pressure to delay termination of pregnancy as optimally as possible. Aromatherapy has the potential to lower blood pressure and improve sleep quality in preeclampsia. The purpose of this study was to determine the effect of aromatherapy on reducing blood pressure and improving sleep quality. The design used in this study is a quasi-experimental study with a pretest-posttest control group design. Respondents in this study were 60 preeclampsia mothers in the treatment room of RSUD dr. Soetomo during the months of February to September that randomly assigned to the treatment and control groups. The sampling technique used is purposive sampling. Aromatherapy (lavender, ylang-ylang, and bergamot) was conducted for three consecutive days. A sphygmomanometer was used to measure blood pressure. Paired sample and unpairesd sample t-test were used for data analysis. There was a significant difference in systolic and diastolic blood pressure between the intervention and control groups with systolic p-value = 0.010 and diastolic p-value = 0.021. There is an effect of lavender, ylang-ylang, and bergamot aromatherapy on reducing blood pressure in preeclamptic mothers during conservative treatment.

EFFECIVENESS OF SOME AROMATIC OILS TREATMENTS ON QUALITY CONSERVATION OF PEPPERMEN FRESH CUT HERB UNDER COLD STORAGE

The effect of lavender, lemongrass and thyme volatile oils as a supplementary cold storage treatments on quality preservation of fresh cut herb of Menthe piperita L. , during storage for 15 days at 5°C and 7°C followed by 5 days at 20°C, as a marketing condition simulation, was evaluated during 2018 and 2019 seasons. Physical properties, chemical constituents, respiration rate and volatile oil contents were recorded. The results illustrated that discarded herb %, weight loss %, and external appearance (scale) were greatly affected by both factors of the study. The great effect in this respect was obtained with storage at 5°C than 7°C and the effect was also continuous during marketing period at 20°C. An evident decrease in discarded herb % and weight loss % were obtained due to the applied treatments, whereas external appearance values were higher with applied treatments than control during cold storage durations and marketing period. Aromatic oils treatments with 0.50% of lavender, lemongrass and thyme oils were effective than 0.25% of the three aromatic oils. However, chemical constituents i.e total chlorophyll, L-ascorbic acid and total phenols of fresh cut herb were scored highly increases by storage at 5°C than at 7°C storage conditions. Furthermore, The richest chemical constituents mentioned above were obtained with 0.50% of the three aromatic oils treatments and with superior for marketing durations for 5 days at 20°C. On contrary, total acidity of fresh cut herb recorded the minimum values with applied treatments than control (except the treatment of 0.25% thyme oil) during all cold storage durations and marketing period. On the reverse , electrolyte leakage and respiration rate values were controlled and minimized with the applied aromatic oils treatments under 5°C or 7°C cold storage conditions and followed by 5 days at 20°C as a marketing period. The decreases of both electrolyte leakage and respiration rate of fresh cut herb either with cold storage or due to the applied treatments are considered a good indicators to increase storage longevity and high quality. Meanwhile, volatile oil was greatly affected by both cold storage conditions and supplementary refrigeration treatments with lavender, lemongrass and thyme aromatic oils. Conclusively , it could be concluded that the peppermint fresh cut herb can be treated with lavender, lemongrass and thyme aromatic oils before storage at 5°C for 15 days , handling and marketing under 20°C to conserve the quality of the herb.

The effect of lavender (Lavandula angustifolia) essential oil as a drinking water supplement on the production performance, blood biochemical parameters, and ileal microflora in broiler chickens

The aim of this study was to evaluate growth performance, selected biochemical blood parameters, and the microbiota of ileal digesta in broiler chickens provided with drinking water containing an addition of natural lavender essential oil (LEO). The experiment was carried out on a commercial farm using n = 300 unsexed Ross-308 broiler chickens. One-day-old chicks were randomly assigned to three groups of 100 chickens each (five replications, 20 individuals each). The control group broilers were provided with drinking water without the addition of LEO. Groups LEO1-42 and LEO22-42 had access to water containing 0.4ml/L LEO (for 6h/day) from days 1 to 42 (LEO1-42) and 22 to 42 (LEO22-42). Body weight, feed intake, water intake, and mortality were recorded throughout the experiment. The analyses reveal that the addition of LEO has a positive effect on body weight in the second period of rearing (d 22-24). Treatment broilers (LEO1-42 and LEO22-42) weighed on average 6.35% more compared to the control (P < 0.01). LEO addition positively affected weight gains and feed conversion ratio (P < 0.01) in the second period of rearing (d 22-24). No differences were found between the groups feed intake, water intake, survival rate, and blood biochemical parameters (P > 0.05). The addition of LEO to drinking water had a positive impact on the gut microflora of the ileum: the numbers of pathogenic microorganisms decreased (Escherichia coli and coliform) while the number of probiotic bacteria increased (P < 0.01).

Effect of lavender (Lavandula angustifolia) and melissa (Melissa Officinalis) waste on quality and shelf life of bread

The effect of lavender (Lavandula angustifolia) and melissa (Melissa Officinalis) waste on preparation, characteristics and shelf life of bread was investigated. It was found that lavender and melissa waste, generated yearly in large amounts, were rich on polyphenols (especially rosmarinic acid) and aroma compounds, and exhibited high antioxidant and antimicrobial activity. The bread with 2.5% lavender waste was characterized with the highest loaf volume and loaf specific volume. The total dietary fiber increased three times and the polyphenols and flavonoids increased more than four times for breads with added 5% lavender and melissa waste, compared to control sample. The breads with 2.5% and 5% added lavender waste had increased shelf life (up to 96 h) compared to control, and no fungal or bacterial spoilage was observed during storage at 22 °C, 30 °C and 37 °C for four days. The sensory evaluation demonstrated that the consumers preferred mainly bread with 2.5% lavender waste.

Effect of Lavender (Lavandula angustifolia) Essential Oil on Acute Inflammatory Response.

Lavandula angustifolia is a plant of Lamiaceae family, with many therapeutic properties and biological activities, such as anticonvulsant, anxiolytic, antioxidant, anti-inflammatory, and antimicrobial activities. The aim of this study was to evaluate the effect of Lavandula angustifolia Mill. essential oil (LEO) on acute inflammatory response. LEO was analyzed using gas chromatography-mass spectrometry (GC-MS) and nuclear magnetic resonance spectroscopy (NMR) methods and showed predominance of 1,8-cineole (39.83%), borneol (22.63%), and camphor (22.12%). LEO at concentrations of 0.5, 1, 3, and 10 μg/ml did not present in vitro cytotoxicity. Additionally, LEO did not stimulate the leukocyte chemotaxis in vitro. The LEO topical application at concentrations of 0.25, 0.5, and 1 mg/ear reduced edema formation, myeloperoxidase (MPO) activity, and nitric oxide (NO) production in croton oil-induced ear edema model. In carrageenan-induced paw edema model, LEO treatment at doses of 75, 100, and 250 mg/kg reduced edema formation, MPO activity, and NO production. In dextran-induced paw edema model, LEO at doses of 75 and 100 mg/kg reduced paw edema and MPO activity. In conclusion, LEO presented anti-inflammatory activity, and the mechanism proposed of LEO seems to be, at least in part, involving the participation of prostanoids, NO, proinflammatory cytokines, and histamine.

The effect of lavender (Lavandula stoechas) on the shelf life of a traditional food: hamsi kaygana

Abstract This study aimed to determine the effect of Lavandula stoechas, which is intensively grown in Mugla and known as lavender, on the meat quality and shelf life of hamsi kaygana, a traditional food in the Black Sea Region of Turkey. The study groups consist of the control group (K), a group containing 0.1% (A), 0.5% (B), and 1% (C) lavender. After performing the initial analyses, all groups were stored at 4 ± 1 °C. During the storage, the proximate composition, sensory, physicochemical, chemical and microbiological analyses were carried out. According to the chemical results, the lavender added to hamsi kaygana at the rates of 0.5% and 1% had an antioxidant effect and TBA obtained on day 20 in group C did not exceed the limit values. It draws attention that lavender has a positive effect on TVB-N. There was less development in the groups in which lavender was added in microbiological terms. The best score in terms of sensory acceptance correlate well within the group B during storage (1 to 9 days) was evaluated. This study has revealed that hamsi kaygana, can be transported to wider markets, by increasing its durability with spices such as lavender and longer-term preservation and easy transportation with different packaging techniques.

Comparison of the effect of lavender and bitter orange on sleep quality in postmenopausal women: A triple-blind, randomized, controlled clinical trial

ABSTRACTThis trial compared the effects of lavender and bitter orange on sleep quality in postmenopausal women. This trial was conducted in 2015. Eligible postmenopausal women were allocated into one of two intervention groups or a control group (n = 52 per group) in a 1:1:1 ratio using a randomized block design. Intervention groups received 500 mg capsules containing only bitter orange or lavender flower powder, and the control group received 500 mg capsules containing starch. The Pittsburgh Sleep Quality Inventory was used before and eight weeks after starting the intervention. Data analyses were based on intention to treat. A one-way ANOVA showed a slightly significant difference in mean sleep score among the three groups before the intervention (p = .045). The general linear model, adjusted for baseline sleep score and confounding factors, showed significant differences among the groups in the mean sleep score after eight weeks of treatment (p < .001). Bitter orange and lavender significantly improved the mean sleep score compared with the control group (p < .001 and p = .003, respectively). The positive effect of bitter orange and lavender on sleep quality in postmenopausal women suggests that they can be used to improve sleep quality in such women.

Effect of lavender and lemon balm extracts on fatty acid profile, chemical quality parameters and sensory quality of vacuum packaged anchovy (Engraulis encrasicolus) fillets under refrigerated condition

The impact of natural plant extracts on chemical parameters, fatty acid profile and sensory properties of vacuum packed anchovy was investigated refrigerated condition (2±1 °C). The anchovy fillets were separated into three groups; which were immersed in 1% French lavender (FL) or lemon balm (LB) extract and the control (C) without plant extract. Along with sensory analysis, the shelf-life of anchovies was 7 days for control and 11 days for both treated extracts. At the end of the storage period, the higher PUFA and omega-3 values were found as 24.43%, 30.97% and 27.88% for C group, FL and LB treatments, respectively. In addition, at the limit of acceptability, TVB-N values reached 41.17 mg/100 g for C group (7 days), 37.42 mg/100 and 42.86 mg/100 g for FL and LB batches (9 days), respectively. Lower PV and TBA values were observed in the fish fillets that treated the LB extract comparison with the other groups (P ≤ 0.05). Among samples, the application of plant extract caused lower value of FFA and pH compared to control group. These results suggest that treatment with FL and LB extracts prevents development of lipids oxidation and reduces the TVB-N values in anchovy's fillets resulting in shelf-life extension.

Antibacterial potential of Urtica dioica and Lavandula angustifolia extracts against methicillin resistant Staphylococcus aureus isolated from diabetic foot ulcers

Despite the antibacterial potential of plant extracts against several bacterial infections, until now, no major studies have been published about the effect of lavender and nettle leaves against methicillin-sensitive and methicillin-resistant strains of Staphylococcus aureus (MSSA and MRSA, respectively). Thus, the authors studied their antibacterial potential against MSSA and MRSA from diabetic foot ulcers in order to find alternatives to the systematic use of antibiotics. Phenolic acids, flavonoids, flavones and flavonols were extracted from lavender and nettle leaves and characterized by HPLC-DAD/Vis. Disc diffusion assay and minimum inhibitory concentration (MIC) were used to assess their antibacterial activity. A direct association between the high content of hydroxycinnamic acids (chlorogenic acid, caffeic acid, rosmarinic acid) and flavonoids (quercetin) and decreasing bacterial growth activity was noted. The fact that lavender and nettle are rich in hydroxycinnamic acids and quercetin seems to explain the high antibacterial potential of these plant and the differences between them.

Effect of lavender (&lt;i&gt;Lavandula Stoechas&lt;/i&gt;) essential oil on growth performance, carcass characteristics, meat quality and antioxidant status of broilers

The study evaluated the effect of essential oils from lavender (Lavandula stoaches) (LEO), on growth performance, carcass quality and antioxidant status of broilers. Three nutritionally adequate diets were composed with the addition of LEO at 0, 24, and 48 mg/kg of feed. The diets were fed as mash in the starter (d 0–21) and grower (d 22–39) phases. A total of 405 day-old chicks (Ross-308) were allocated to the three dietary treatments, each with three replicate pens with 45 birds per pen. After the first 21-day feeding period, the bodyweight of chicks fed 24 mg/kg LEO was higher (P <0.01) than the 48 mg/kg LEO treatment, but only slightly higher than that of the untreated group. Diets with 24 and 48 mg/kg of LEO tended to increase final bodyweight of birds at 39 days old. No differences were observed for feed intake (FI), feed conversion ratio (FCR) and mortality among treatments. Feeding chickens on a diet with added LEO significantly reduced the relative weight of liver (P <0.01) compared with the control (CNT) group. Percentage of spleen weight of birds fed 24 mg/kg LEO was lower (P <0.05) than for those who received 48 mg/kg LEO. However, it was similar to that of the CNT. Birds fed diets supplemented with 24 and 48 mg/kg LEO had breast meat with higher brightness (L* value) and higher concentration of superoxide dismutase (SOD) compared with birds that did not receive LEO. Based on the data, it can be concluded that LEO could be used as a growth promoter in broiler nutrition with potential improvements in breast meat quality. ______________________________________________________________________________________ Keywords : Antioxidative activity, broiler, growth promoting effects, lavender oil, meat yield,

Some questions about herbal and traditional medicine.

Dear Editor, In recent years we have witnessed the widespread use of herbal and traditional medicines. In many cases, people use traditional treatments arbitrarily and without consultation with a qualified person (1). As a teacher, I have frequently seen a number of my colleagues and others use herbal medicines and traditional methods for their medical problems. Looking at the papers published in this journal, it could be inferred that nurse researchers have a particular interest in the impact of herbal, traditional and complementary medicine on the care and treatment of certain physical and psychological problems. For example Sodouri et al. studied the effect of Zataria multiflora on the severity of premenstrual syndrome and reported that this herb was not effective on premenstrual pain (2). In addition, Vakilian and Keramat examined the effect of lavender on the first and second stages of labor. They reported that lavender essential oil aroma could be used to decrease the length of a delivery (3). A number of other studies have examined the effects of methods such as, massage therapy and acupressure, on vital signs and blood cortisol levels in patients with heart disease (4, 5), and surgical patients (6), and they reported that these methods were useful. Nurses desire to study the effects of herbal medicine and traditional treatments is evident in that such articles can also be found abundantly in other Iranian journals (7-9). Moreover, an Iranian nursing journal has been named, 'Complementary Medicine Journal of Faculty of Nursing and Midwifery'. Although it represents an interest in the development of health science through an approach based on national traditional medicine, questions remain concerning the extent to which the use of herbal medicines and traditional treatments are effective, in comparison with current modern medicine. Are the dosage, frequency of use, and adverse effects, of herbal medicines and traditional treatments as clear as with drugs that are commonly used in modern medicine? Furthermore, can herbal and traditional methods be used alone or should they stand alongside conventional treatments?

The Effects Caused by Lavender and Rosemary for Salivary Cortisol, Stress Levels and Mood Alteration

【This study is being conducted in order to confirm the effects of inhaling method for aromatherapy on cortisol which is a stress hormone by the saliva test method. An attempt is being made to dertermine if there are any differences between the effect of lavender and rosemary when concidering their effects on the cortisolsl. The test shows a statistically significant decrease in the cortisol levesl(Table 4), and as far as the comparison of the effects between lavender(N=10) and rosemary(N=10) is concerned, the lavender group show a p-value of .005 which means that there are no statistical significances; while the rosemary group show p-values of .081 meaning that there is a decrease in cortisol levels, which is statistically significant(Table 5). It has been proven that the saliva test method is a practical and scientific method when confirming the effects of aromatherapy and also a convenient method for both of the test coordinator and the subjects. Results of all 20 subjects showed similar results obtained by means of conventional blood tests. However, the rosemary group shows statistically significant decrease in cortisol level compared to the lavender group, thus proving that the test method for studying the effect of aromatherapy on stress is valid. Further studies should be conducted in order to investigate the differences in the effects of the cortisol level at different concentrations of the aroma.】

Effect of cinnamon and lavender oils on FtsZ gene expression in the Staphylococcus aureus ATCC 29213

This study was designed to determine the effect of lavender and cinnamon oils on FtsZ gene expression in Staphylococcus aureus ATCC 29213. The cinnamon and lavender oils at least partially results from the inhibition of FtsZ transcription and disruption of cell division process at the level of the septum synthesis, what is similar to mechanisms of drug action used in anti-staphylococcal therapies. The presented results could be an important background for the further detailed research, which is needed to clarify the effect of essential oils on FtsZ synthesis at the posttranscriptional level and other stages of cell division process of S. aureus and other pathogenic bacteria.

Lavender and the nervous system.

Lavender is traditionally alleged to have a variety of therapeutic and curative properties, ranging from inducing relaxation to treating parasitic infections, burns, insect bites, and spasm. There is growing evidence suggesting that lavender oil may be an effective medicament in treatment of several neurological disorders. Several animal and human investigations suggest anxiolytic, mood stabilizer, sedative, analgesic, and anticonvulsive and neuroprotective properties for lavender. These studies raised the possibility of revival of lavender therapeutic efficacy in neurological disorders. In this paper, a survey on current experimental and clinical state of knowledge about the effect of lavender on the nervous system is given.
