Effectiveness of aromatherapy in decreasing maternal anxiety for a sick child undergoing infusion in a paediatric clinic

The Effect of Coffee Aromatherapy on Reducing Fatigue and Stress Levels of Female Caregivers Caring for the Elderly in Hospitals

Background. The exploration of coffee as an aromatherapy in the health service has not been widely carried out. In many cases, aromatherapy has been shown to reduce stress and fatigue. Purpose.   To analyzes the effect of coffee aromatherapy on the fatigue and stress levels of female caregivers caring for the elderly at the University of Sumatera Utara Hospital (USU Hospital), in Medan. Methods. This is a quasi-experiment one group pretest posttest design.  The research involved 16 caregivers were given a treatment of coffee oil by inhalation for 15 minutes for three consecutive days, without coffee oil inhalation and 10% of coffee oil concentration on the first day, 20% on the second day, and 30% on the third day. Each sample received a pretest and posttest in the form of stress and fatigue instruments.  The data analysis performed was univariate in order to describe the properties of each variable examined and analyze the mean score. Similarly, bivariate analysis with the Analysis of Variance (ANOVA) statistical test was used to determine the effect of coffee aromatherapy on reducing the fatigue and stress level. Results. The result showed that most caregivers were elderly children with an average age of 38 years, 81.3% assisted in caring for the elderly, and actively working outside the home. Based on the ANOVA test, the data showed that the administration of coffee aromatherapy for three consecutive days has no effect on female caregivers’ fatigue and stress level.  However, the mean score showed a decrease in fatique and stress level before and after coffee oil inhalation in three days.  Conclusion. It is necessary to provide coffee oil aromatherapy intervention with a longer duration to have an effect on reducing caregiver fatique and stress in the future, so the results are expected to form the basic data for the design of nursing interventions based on complementary therapies in order to reduce the fatigue and stress of caregivers while providing care to the hospitalized elderly.

Effects of aromatherapy on anxiety: A meta-analysis of randomized controlled trials

SCOPE

The effects of aromatherapy on relieving anxiety were controversial. The purpose of this meta-analysis was to evaluate the effects of aromatherapy on anxiety in patients.

METHODS AND RESULTS

We searched randomized controlled trials (RCTs) about aromatherapy on decreasing anxiety on PUBMED, WEB OF SCIENCE (January 1990 to October 2019), COCHRANE LIBRARY, EMBASE (updated to October 2019), and the Chinese databases CNKI, WanFang and CBMD. Twenty-five articles (Thirty-two trials) were included in this meta-analysis. The data of scale scores of Spielberger State-Trait Anxiety Inventory (STAI) were extracted. The pooled results demonstrated that inhalation and massage aromatherapy significantly decreased anxiety levels in different conditions. The weighted mean difference was -5.16 for State Anxiety Inventory (SAI) (95%CI: -5.78, -4.55, p<0.001) and -2.85 for Trait Anxiety Inventory (TAI) (95%CI: -3.95, -1.75, p<0.001). No side effects were mentioned in all of studies.

CONCLUSION

The meta-analysis suggested that aromatherapy with different essential oils could alleviate anxiety significantly no matter the reason of anxiety. However, the proper dosage of essential oils needs further research.

Effects of sweet orange aromatherapy on pain and anxiety during needle insertion among patients undergoing hemodialysis: A quasi-experimental study

PURPOSE

Patients undergoing hemodialysis experience pain and anxiety during needle insertion, and the scientific interest in aromatherapy in reducing pain and anxiety is increasing. Thus, this study aimed to determine the effects of sweet orange aromatherapy on pain and anxiety during needle insertion in hemodialysis.

DESIGN

Quasi-experimental, pretest, and posttest.

METHODS

This study was carried out among 50 patients with chronic kidney disease who were non-randomly assigned to either sweet orange aromatherapy or calm breathing in three outpatient hemodialysis centers in the Philippines between July and August 2015. The numeric rating scale and adapted state-trait anxiety inventory were utilized to measure pain and anxiety.

RESULTS

After the intervention, both the pain and anxiety scores were significantly lower for patients who received sweet orange aromatherapy than those who received calm breathing. The results obtained modest effect sizes that imply high practical significance.

CONCLUSION

The sweet orange aromatherapy can be effective in reducing pain and anxiety. Thus, this can be used by nurses as an alternative and complementary approach to reduce both pain and anxiety in painful procedures like needle insertion.

Tunisian Clematis flammula Essential Oil Enhances Wound Healing: GC-MS Analysis, Biochemical and Histological Assessment

The aerial part of Clematis flammula (Ranunculaceae) has been traditionally used in the treatment of skin diseases including mycotic infection in the Tunisian traditional medicine. The study was undertaken to extract and determine the essential oil chemical composition of Clematis flammula aerial parts and to assess the potential of anemonin in wound healing on mechanically wounded wistar rats. The essential oil was obtained by hydrodistillation and analyzed by GC-MS. Anemonin was isolated and then incorporated as active in a cream for which the cytotoxicity was evaluated by methyl thiazolyl tetrazolium (MTT)-based colorimetric assay. Then, its potential in wound healing on mechanically wounded wistar rats was assessed. The GC-MS analysis showed that the major compound was protoanemonin (86.74%) which spontaneously dimerised in part to form the anemonin. The wound healing activity of anemonin cream exhibited a non toxic potential of anemonin at a concentration of 25 µg/mL with a cell migration efficiency that reaches more than 80% after 48 hours of treatment. Wound healing efficiency was evaluated by monitoring morphological and skin histological analyses. Comparable wound surface reduction of the group treated by anemonin cream (p ≥ 0.05) when compared to the reference treated group. The skin histological analysis showed the completely wound closure. Antioxidant activity was assessed by the malondialdehyde (MDA) rates and antioxidant enzymes (glutathione peroxidase (GPx) and catalase) determination. The results provided strong support for the effective wound healing activity of anemonin cream, making it a promising candidate as a therapeutic agent in tissue repairing processes.

Biological Activities and Safety of Citrus spp. Essential Oils

Citrus fruits have been a commercially important crop for thousands of years. In addition, Citrus essential oils are valuable in the perfume, food, and beverage industries, and have also enjoyed use as aromatherapy and medicinal agents. This review summarizes the important biological activities and safety considerations of the essential oils of sweet orange (Citrus sinensis), bitter orange (Citrus aurantium), neroli (Citrus aurantium), orange petitgrain (Citrus aurantium), mandarin (Citrus reticulata), lemon (Citrus limon), lime (Citrus aurantifolia), grapefruit (Citrus × paradisi), bergamot (Citrus bergamia), Yuzu (Citrus junos), and kumquat (Citrus japonica).

Wound healing potential of lavender oil by acceleration of granulation and wound contraction through induction of TGF-β in a rat model

Background

Although previous studies have suggested that lavender oil promote wound healing, no study has examined the molecular mechanisms of its effect. In this study, we investigated the effect of lavender oil on various steps of wound healing and its molecular mechanism, focusing on transforming growth factor-β (TGF-β).

Methods

Circular full-thickness skin wounds were produced on rats. Control solution or lavender oil was topically applied to the wounds on alternating days for 14 days.

Results

The area of wounds topically treated with lavender oil was significantly decreased as compared to that of wounds of control rats at 4, 6, 8, and 10 days after wounding. Topical application of lavender oil induced expression of type I and III collagen at 4 days after wounding, accompanied by an increased number of fibroblasts, which synthesize collagen. Induced expression of type III collagen by topical application of lavender oil was reduced to control level at 7 days after wounding although increased expression of type I collagen still continued even at 7 days, suggesting rapid collagen replacement from type III to type I in wounds treated with lavender oil. Importantly, expression of TGF-β in wounds treated with lavender oil was significantly increased as compared to control. Moreover, an increased number of myofibroblasts was observed in wounds treated with lavender oil at 4 days after wounding, suggesting promotion of differentiation of fibroblasts through induction of TGF-β, which is needed for wound contraction.

Conclusion

This study demonstrated that topical application of lavender oil promoted collagen synthesis and differentiation of fibroblasts, accompanied by up-regulation of TGF-β. These data suggest that lavender oil has the potential to promote wound healing in the early phase by acceleration of formation of granulation tissue, tissue remodeling by collagen replacement and wound contraction through up-regulation of TGF-β. The beneficial effect of lavender oil on wound healing may raise the possibility of new approaches as complementary treatment besides conventional therapy.

Aromatic effects of a Japanese citrus fruit-yuzu (Citrus junos Sieb. ex Tanaka)-on psychoemotional states and autonomic nervous system activity during the menstrual cycle: a single-blind randomized controlled crossover study

BACKGROUND

Yuzu (Citrus junos Sieb. ex Tanaka), a yellow-golden colored citrus fruit, has traditionally been used to promote psychosomatic health in Japan. While the yuzu produces a distinctive, pleasing aroma of citrus and floral, the efficacy of its fragrance remains unknown. The present study investigated the soothing effects of the fragrance of yuzu essential oil from the perspective of autonomic nervous system activity, which plays a crucial role in the integrity of the mind-body connection.

METHODS

Twenty one women in their 20s participated in a single-blind randomized controlled crossover study. Subjects were examined twice each in the follicular and late-luteal phases. Two kinds of aromatic stimulation (yuzu and water as a control) were used. This experiment measured heart rate variability (HRV) reflecting autonomic nervous system activity and used the Profile of Mood States (POMS) as a psychological index before and after the aromatic stimulation.

RESULTS

Only a 10-min inhalation of the yuzu scent significantly decreased heart rate and increased high frequency power of HRV reflecting parasympathetic nervous system activity, regardless of menstrual phase. This significant physiological effect continued for at least 25 min. In addition, the POMS tests revealed that inhalation of the aromatic yuzu oil significantly decreased total mood disturbance, a global measure of affective state, together with two POMS subscales-tension-anxiety and fatigue, as long as 35 min after the aroma stimulation, both in the symptomatic late-luteal and non-symptomatic follicular phases.

CONCLUSIONS

The present study provides the novel information that yuzu's aromatic effects could serve to alleviate negative emotional stress, which, at least in part, would contribute to the improvement of parasympathetic nervous system activity.

The Clinical Effects of Aromatherapy Massage on Reducing Pain for the Cancer Patients: Meta-Analysis of Randomized Controlled Trials

Purpose. Aromatherapy massage is an alternative treatment in reducing the pain of the cancer patients. This study was to investigate whether aromatherapy massage could improve the pain of the cancer patients. Methods. We searched PubMed and Cochrane Library for relevant randomized controlled trials without language limitations between 1 January 1990 and 31 July 2015 with a priori defined inclusion and exclusion criteria. The search terms included aromatherapy, essential oil, pain, ache, cancer, tumor, and carcinoma. There were 7 studies which met the selection criteria and 3 studies were eventually included among 63 eligible publications. Results. This meta-analysis included three randomized controlled trials with a total of 278 participants (135 participants in the massage with essential oil group and 143 participants in the control (usual care) group). Compared with the control group, the massage with essential oil group had nonsignificant effect on reducing the pain (standardized mean difference = 0.01; 95% CI [-0.23,0.24]). Conclusion. Aromatherapy massage does not appear to reduce pain of the cancer patients. Further rigorous studies should be conducted with more objective measures.
