Chung YH, Chen SJ, Lee CL, Chang YS. Kokedama and essential oils had a relaxing psychophysiological effect on Taiwanese women during the COVID-19 pandemic. Explore (NY) 2024; 20:371-379. [PMID: 37777433 DOI: 10.1016/j.explore.2023.09.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 09/21/2023] [Accepted: 09/24/2023] [Indexed: 10/02/2023]
Abstract
BACKGROUND During the COVID-19 pandemic, we designed an indoor nature activity program for citizens with a relaxing effect similar to forest bathing to promote their physical and mental health. We integrated an indoor horticultural activity (Kokedama) with the breathing of Pseudotsuga menziesii (P. menziesii) and Lavandula angustifolia (L. angustifolia) essential oils (EOs) with the goal of creating a nature-inspired environment in an indoor setting where participants would feel as if immersed in a forest atmosphere. METHODS Taiwanese women participated in the experiment, using two Saturday mornings, one Saturday in a university classroom in the city center; and the other Saturday in a workshop in a Suburban Park. Intra-group comparisons were used to assess the Physiological responses to urban and suburban environmental stimuli and measured self-reported psychological responses. We recorded parameters associated with heart-rate variability and brainwaves. We also administered the State-Trait Anxiety Inventory-State (STAI-S) questionnaire before and after the participants had completed the entire program. RESULTS After the participants had breathed the P. menziesii and L. angustifolia EOs, the levels of some physiological parameters increased (standard deviation of normal-to-normal intervals, normalized high frequency, and high alpha wave) and those of others decreased (normalized low frequency, low- to high-frequency ratio power, high beta wave, and gamma wave). These findings were corroborated by the data from the STAI-S questionnaires. CONCLUSIONS The psychophysiological data from this study provide significant scientific evidence for the health benefits of an indoor nature activity program in women.

Effects of lavender oil on odor elimination, ostomy adjustment and quality of life in patients with permanent colostomy: A randomized controlled trial. Eur J Oncol Nurs 2024; 68:102471. [PMID: 38016202 DOI: 10.1016/j.ejon.2023.102471] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 11/13/2023] [Accepted: 11/16/2023] [Indexed: 11/30/2023]
Abstract
PURPOSE The aim of this study is to assess the impact of lavender oil on odor elimination, ostomy adjustment and quality of life outcomes in patients with permanent colostomy. Specifically, the study aims to compare the outcomes of an experimental group receiving lavender oil intervention with those of a control group. METHODS A randomized controlled trial design was employed, including an experimental group receiving lavender oil intervention and a control group receiving standard care. The study participants were patients with permanent colostomy. Various variables were assessed, including odor scale, work and social functioning, sexuality and body image, stoma function, financial concerns, acceptance, anxiety/preoccupation, social engagement and anger. RESULTS The post-scores assessment showed significant differences between the experimental and control groups in all variables. The experimental group exhibited significantly more positive outcomes concerning the reduction of odor (p<0.001), performance in the workplace (p<0.001), body image connected to sexuality (p<0.001), stoma functionality (p<0.001), financial worries (p=0.005), acceptance levels (p<0.001), anxiety levels (p<0.001), social involvement (p<0.001), and irritability (p<0.001). Effect sizes were substantial (=0.88-0.98 in all variables but one), indicating significant differences in average scores before and after the intervention. CONCLUSION The findings of this study suggest that lavender oil intervention effectively improved odor elimination, ostomy adjustment and quality of life outcomes in patients with permanent colostomy.

[PMID: 38286818 PMCID: PMC10825141 DOI: 10.1038/s41405-024-00186-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Revised: 12/16/2023] [Accepted: 12/18/2023] [Indexed: 01/31/2024] Open
Abstract
AIM This study aimed to evaluate the efficacy of aromatherapy with Lavender-Neroli essential oil combined with background music in reducing dental anxiety and pain during anesthesia in children. MATERIALS AND METHODS A total of 56 children aged 6-10 years old who needed dental treatment with inferior alveolar nerve injection (IANB) were randomly divided into two groups: Group 1 (Experimental, n = 28) aromatherapy with music group, and Group 2 (Control, n = 28) the placebo group. Children in the group 1 were asked to inhale the aromatic blend of Lavender-Neroli essential oil using a nasal mask similar to one that is used for nitrous oxide after modifying it by adding a 3D printed box on its circle hole and listening to their favorite music as a background before 5 min and during anesthesia, meanwhile in the placebo group children were asked to wear an empty nasal mask. Anxiety and pain were been assessed before and after anesthesia using the self-report anxiety scale Facial image scale (FIS), Observational pain assessment scale Face-Legs-Activity-Cry-Consolability (FLACC), heart rate, SPO2 saturation, diastolic and systolic blood pressure. RESULTS Dental anxiety and vital signs except SPO2 saturation were significantly lower in the aromatherapy with music group when compared to the control group (p < 0.05), with no differences in pain perception between groups (p = 0.176). CONCLUSIONS Aromatherapy with Lavender-Neroli oil combined with music seems to be a useful and safe non-pharmacologic technique for managing dental anxiety in children.

An Investigation of the Effect of Virtual Reality on Alleviating Anxiety in Patients With Breast Cancer Undergoing Radiation Therapy: A Randomized Controlled Trial. Int J Radiat Oncol Biol Phys 2023; 117:1191-1199. [PMID: 37451473 DOI: 10.1016/j.ijrobp.2023.06.275] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Revised: 05/31/2023] [Accepted: 06/26/2023] [Indexed: 07/18/2023]
Abstract
PURPOSE The aim of this study was to evaluate the anxiety-reducing effects of virtual reality (VR) on patients with breast cancer undergoing adjuvant radiation therapy (RT). METHODS AND MATERIALS This randomized controlled trial was conducted among patients with breast cancer receiving RT at a single institution. Of 196 enrolled and randomized patients, 97 were assigned to a VR explanation group (intervention) and 99 were assigned to the standard-of-care group (control). Anxiety levels were measured using the Amsterdam Preoperative Anxiety and Information Scale (APAIS) as the primary endpoint and the State-Trait Anxiety Inventory (STAI) and Linear Analogue Scale Assessment (LASA) as secondary endpoints. Knowledge of the RT procedure, patient satisfaction, and time spent for counseling were also assessed. RESULTS Intervention significantly reduced patient anxiety immediately, not only on the primary endpoint, APAIS, but also on the STAI and LASA anxiety scales. Specifically, in the intervention group, there were immediate reductions of 26.0%, 16.1%, and 55.8% for APAIS, STAI, and LASA, respectively, whereas in the control group, the respective reductions were 8.1%, 8.5%, and 13.7%. Among the 3 anxiety scales, long-term anxiety reduction was observed only when anxiety was measured by LASA. Subgroup analyses showed that the effect on anxiety did not differ based on the physician, baseline anxiety level, use of hormone therapy, or health literacy. The intervention also significantly improved knowledge of the RT procedure (81.9/100 vs 76.8/100; P = .006) and patient satisfaction with the explanation manner (6.56 vs 5.72; P < .001) compared with the control group. CONCLUSIONS Immersive VR applied to the current procedure reduces anxiety during RT planning for patients with breast cancer. Further research is necessary to investigate the long-term effects of VR on anxiety.

Gastroenterol Nurs 2023; 46:376-385. [PMID: 37289849 DOI: 10.1097/sga.0000000000000754] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Accepted: 05/01/2023] [Indexed: 06/10/2023] Open
Abstract
The purpose of this study was to determine the effect of lavender oil inhalation on the anxiety and comfort levels of patients scheduled for colonoscopy. Seventy-three experimental group patients scheduled for colonoscopy at a training and research hospital in the west of Turkey in June to September 2022 and 72 control group patients were included in this randomized, controlled, prospective study. Minimal sedation (propofol 2-3 mg/kg) was applied in both groups. Lavender inhalation was applied to the experimental group, whereas the control group patients received nursing care (vital sign monitoring, prevention of complications, and rest). The State-Trait Anxiety Inventory and the Shortened General Comfort Questionnaire were used for pre- and postprocedural data collection. Median ages were 53.00 years (47.25-59.00) in the experimental group patients and 51.00 (44.00-59.5) in the control group. Although postprocedural state anxiety scores were lower in the experimental group compared with the control group, the difference was not statistically significant ( p = .069). The general postcolonoscopy comfort score was significantly higher in the experimental group compared with the control group ( p < .001). Trait anxiety scores also increased as the number of colonoscopies increased in both groups. We conclude that lavender oil inhalation, a simple and inexpensive intervention, increases patient comfort while exhibiting a positive, albeit statistically insignificant, effect on anxiety.

Heliyon 2023; 9:e18492. [PMID: 37554839 PMCID: PMC10404968 DOI: 10.1016/j.heliyon.2023.e18492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 07/17/2023] [Accepted: 07/19/2023] [Indexed: 08/10/2023] Open
Abstract
Neurological diseases affect the nervous system, including the brain, spinal cord, cranial nerves, nerve roots, autonomic nervous system, neuromuscular junctions, and muscles. Herbal medicine has long been used to cure these diseases. One of these plants is lavender, which is composed of various compounds, including terpenes, such as linalool, limonene, triterpenes, linalyl acetate, alcohols, ketones, polyphenols, coumarins, cineole, and flavonoids. In this review, the literature was searched using scientific search engines and databases (Google Scholar, Science Direct, Scopus, and PubMed) for papers published between 1982 and 2020 via keywords, including review, lavender, and neurological disorders. This plant exerts its healing effect on many diseases, such as anxiety and depression through an inhibitory effect on GABA. The anti-inflammatory effects of this plant have also been documented. It improves depression by regulating glutamate receptors and inhibiting calcium channels and serotonergic factors, such as SERT. Its antiepileptic mechanism is due to an increase in the inhibitory effect of GABA and potassium current and a decrease in sodium current. Therefore, many vegetable oils are also used in herbal medicine. In this review, the healing effect of lavender on several neurological disorders, including epilepsy, depression, anxiety, migraine, and Alzheimer's disease was investigated. All findings strongly support the traditional uses of lavender. More clinical studies are needed to investigate the effect of the plants' pharmacological active constituents on the treatment of life-threatening diseases in humans. The limitations of this study are the low quality and the limited number of clinical studies. Different administration methods of lavender are one of the limitations of this review.

Hedigan F, Sheridan H, Sasse A. Benefit of inhalation aromatherapy as a complementary treatment for stress and anxiety in a clinical setting – A systematic review. Complement Ther Clin Pract 2023; 52:101750. [PMID: 37031643 DOI: 10.1016/j.ctcp.2023.101750] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Revised: 03/07/2023] [Accepted: 03/26/2023] [Indexed: 04/08/2023]
Abstract
OBJECTIVE The purpose of this systematic review is to ascertain the impact of inhalation aromatherapy on stress and anxiety in clinical settings. METHODS A search strategy was developed using various databases. Randomised Controlled Trials (RCTs) as well as single and double-blind pilot clinical studies (non-RCT) using inhalation aromatherapy with an essential oil blend or a single essential oil were examined. All studies included a control intervention and use of a validated measurement tool. The time period under review was years 2000-2021. Due to the high level of heterogeneity and element of bias, a narrative synthesis was conducted. RESULTS The search strategy initially retrieved 628 studies and through application of the selection criteria and the removal of duplicates, 76 studies were selected for review with a total of 6539 patients. In 42% of the RCTs, physiological measures including vital signs and/or salivary cortisol were used in addition to questionnaires. Over 70% of the studies reported a positive effect on anxiety levels in the aromatherapy intervention groups compared with the control. However, in many cases this is limited by the absence of safety data, imprecise reporting of plant species and dosage of essential oil. CONCLUSION Inhalation aromatherapy has the potential to reduce stress and anxiety with data emerging to further support this result across a wide modality of clinical treatments. However, there is a clear need for the development of standard protocols for research in this area, generating measurable results which will create the opportunity for more rigorous evidence-based outcomes.

Abstract
Background and purpose The findings of clinical studies exploring essential oils (EOs) for anxiety remain disputed, and no studies have yet clarified the differences in the efficacy of EOs. The purpose of the study was to directly or indirectly compare the efficacy of different types of EOs on anxiety by pooling the results of randomized controlled trials (RCTs). Methods PubMed, Cochrane Library, Embase, Scopus, Web of Science and the Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched from inception to November 2022. Only full texts of RCTs that investigated the effects of EOs on anxiety were included. The trial data were extracted and the risk of bias was assessed by two reviewers independently. Pairwise meta-analysis and network meta-analysis were performed by Stata 15.1 or R 4.1.2 software. Results Forty-four RCTs (fifty study arms) involving 10 kinds of EOs and 3419 anxiety patients (1815 patients in EOs group and 1604 patients in control group) were included. Pairwise meta-analyses showed that EOs were effective in reducing State Anxiety Inventory scores (SAIS) [WMD = -6.63, 95% CI-8.17, -5.08] and Trait Anxiety Inventory scores (TAIS) [WMD = -4.97, 95% CI-6.73, -3.20]. Additionally, EOs could decrease systolic blood pressure (SBP) [WMD = -6.83, (95% CI -10.53, -3.12), P < 0.001] and heart rate (HR) [WMD = -3.43, (95% CI -5.51, -1.36), P < 0.001]. Network meta-analyses demonstrated that regarding the outcome of SAIS, Jasminum sambac (L.)Ait. (jasmine) was the most effective with a weighted mean difference (WMD) of-13.61 (95% CrI-24.79, -2.48). Followed by Citrus (citrus aurantium L.), which had a WMD of-9.62 (95% CrI-13.32, -5.93). Moderate effect sizes were observed for Rosa rugosa Thunb. (damask rose) (WMD = -6.78, 95% CrI-10.14, -3.49) and Lavandula angustifolia Mill. (lavender) (WMD = -5.41, 95% CrI-7.86, -2.98). Regarding the results of TAIS, citrus aurantium L. was the best ranked intervention with a WMD of-9.62 (95% CrI-15.62, -3.7). Moderate-to-large effect sizes were observed for Citrus limon (L.) Burm. F. (lemon) (WMD:-8.48; 95% CrI-16.67, -0.33) and lavender (WMD:-5.5; 95% CrI-8.7, -2.46). Conclusion According to the comprehensive analysis, EOs are effective in reducing both state anxiety and trait anxiety, and citrus aurantium L. essential oil seems to be the most recommended type of EO for treating anxiety because of its significant effects in reducing SAIS and TAIS.

Abstract
BACKGROUND Clinical research in natural product-based psychopharmacology has revealed a variety of promising herbal medicines that may provide benefit in the treatment of mild mood disorders, however failed to unambiguously indicate pharmacologically active constituents. The emerging role of the microbiota-gut-brain axis opens new possibilities in the search for effective methods of treatment and prevention of mood disorders. PURPOSE Considering the clinically proven effectiveness juxtaposed with inconsistencies regarding the indication of active principles for many medicinal plants applied in the treatment of anxiety and depression, the aim of the review is to look at their therapeutic properties from the perspective of the microbiota-gut-brain axis. METHOD A literature-based survey was performed using Scopus, Pubmed, and Google Scholar databases. The current state of knowledge regarding Hypericum perforatum, Valeriana officinalis, Piper methysticum, Passiflora incarnata, Humulus lupulus, Melissa officinalis, Lavandula officinalis, and Rhodiola rosea in terms of their antimicrobial activity, bioavailability, clinical effectiveness in depression/anxiety and gut microbiota - natural products interaction was summarized and analyzed. RESULTS Recent studies have provided direct and indirect evidence that herbal extracts and isolated compounds are potent modulators of gut microbiota structure. Additionally, some of the formed postbiotic metabolites exert positive effects and ameliorate depression-related behaviors in animal models of mood disorders. The review underlines the gap in research on natural products - gut microbiota interaction in the context of mood disorders. CONCLUSION Modification of microbiota-gut-brain axis by natural products is a plausible explanation of their therapeutic properties. Future studies evaluating the effectiveness of herbal medicine and isolated compounds in treating mild mood disorders should consider the bidirectional interplay between phytoconstituents and the gut microbiota community.

Abstract
The extensive use of antibiotics has resulted in the development of drug-resistant bacteria, leading to a decline in the efficacy of traditional antibiotic treatments. Essential oils (EOs) are phytopharmaceuticals, or plant-derived compounds, that possess beneficial properties such as anti-inflammatory, antibacterial, antimicrobial, antiviral, bacteriostatic, and bactericidal effects. In this review, we present scientific findings on the activity of EOs as an alternative therapy for common oral diseases. This narrative review provides a deeper understanding of the medicinal properties of EOs and their application in dentistry. It not only evaluates the effectiveness of these oils as antibacterial agents against common oral bacteria but also covers general information such as composition, methods of extraction, and potential toxicity. Further nonclinical and clinical studies must be conducted to determine their potential use and safety for treating oral diseases.

Abstract
Background/purpose Dental anxiety and fear in children are major public health concerns. This study aimed to determine the effectiveness of music therapy combined with aromatherapy, in reducing the children's dental anxiety and fear. Materials and methods A total of 128 school-age children aged 10-12 years were randomly allocated into 4 groups: a control group with 32 volunteers, an experimental group that received music therapy, with 33 volunteers, an aromatherapy experimental group with 31 volunteers, and 32 volunteers in an experimental group with music therapy combined with aromatherapy. Results The results found that within-group comparisons before and after the experiment revealed the outcomes with a statistically significant change at the 0.05 level of each group as follows. The control group had increased heart rate. The music therapy group showed decreased dental anxiety and fear and systolic blood pressure. The aromatherapy experimental group exhibited increased oxygen saturation. The experimental group receiving music therapy combined with aromatherapy showed decreased dental anxiety and fear, heart rate, and systolic and diastolic blood pressure as well as increased oxygen saturation values. In addition, it was found that music therapy combined with aromatherapy had a co-influence on dental anxiety and fear (F = 22.22, P < 0.001) and oxygen saturation (F = 17.40, P < 0.001), and the two main treatments also significantly influenced these outcomes at the 0.05 level. Conclusion The results showed that music therapy in combination with aromatherapy reduced children's anxiety and fear of dental services better than a single treatment.

Management of fear and anxiety in dental treatments: a systematic review and meta-analysis of randomized controlled trials. Odontology 2023; 111:20-32. [PMID: 35536282 DOI: 10.1007/s10266-022-00711-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Accepted: 04/15/2022] [Indexed: 01/12/2023]
Abstract
OBJECTIVES This systematic review was to compare the effects of interventions for the management of fear and anxiety for dental treatments. METHODS This research project was applied to PubMed, CENTRAL, Web of Science, Cochrane library databases. The last search was run on March 31st, 2021. A list of references of relevant articles and previous reviews were checked. Qualitative and quantitative analyses were performed. RESULTS A total of 20 eligible randomized controlled trials were included, and 969 participations in experimental group and 892 participations in the control group were involved. Anxiety levels decreased more in intervention groups than in control groups (Z = 3.47, P = 0.0005, SMD = - 0.62, 95% CI - 0.98 to - 0.27). For adults, there was statistical difference between experimental and control groups [Z = 2.14, P = 0.03, 95% CI - 0.54 (- 1.03, - 0.04)], while there was not no such statistical difference in children and adolescents [Z = 1.62, P = 0.11, 95% CI - 0.60 (- 1.32, 0.13)]. Patients experienced a significant decrease in anxiety level using sedation drugs [Z = 2.44, P = 0.01, 95% CI - 0.61 (- 1.10, - 0.12)] and audio-visual distractions [Z = 3.1, P = 0.002, 95% CI - 0.86 (- 1.40, - 0.32)]. For the informative intervention groups, patients did not show significant difference than control groups [Z = 1.22, P = 0.22, 95% CI - 0.55 (- 1.43, 0. 33)]. There was no statistical difference in vital signs [Z = 1.39, P = 0.16, 95% CI - 0.25 (- 0.61, 0.10)] and pain levels [Z = 0.69, P = 0.49; SMD = - 0.06, 95% CI (0.27, 0.11)] between intervention and control groups. CONCLUSIONS Interventions should be used in managing anxiety and fear for dental treatment. It might be effective for anxiety alleviating for adults, but there was a low certainty of evidence that interventions could reduce anxiety level in children and adolescents. Sedation drugs and audio-visual distractions might be useful for managing dental fear and anxiety. Pain levels and vital signs could not be improved form our study. High-quality randomized clinical trials are required for further study.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:15251. [PMID: 36429972 PMCID: PMC9690885 DOI: 10.3390/ijerph192215251] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 11/13/2022] [Accepted: 11/16/2022] [Indexed: 06/16/2023]
Abstract
We evaluated the effects of breathing Pseudotsuga menziesii (P. menziesii) and Lavandula angustifolia (L. angustifolia) essential oils (EOs) during a horticultural activity on older adults. A total number of 92 older adult (71.2 ± 7.7 years old) participants were guided through a leaf printing procedure. In the meantime, water vapor and EOs were diffused in an orderly manner. The heart rate variability-related parameters as well as the brain waves were recorded. In addition, we also collected data for the State-Trait Anxiety Inventory-State (STAI-S) questionnaires before and after the whole indoor natural activity program. The physiological parameters including standard deviation of normal to normal intervals, normalized high frequency (nHF), and high alpha wave increased while the normalized low frequency (nLF), the ratio of LF-to-HF power, high beta wave, and gamma wave decreased following the breathing of P. menziesii and L. angustifolia EOs. These changes indicated a relaxing effect of breathing both EOs during a horticultural activity on older adults. Our results demonstrated a beneficial effect of P. menziesii EO which is as good as a well-known relaxant L. angustifolia EO. This notion was supported by the results of STAI-S. Here we developed an indoor natural activity program for older adults to promote physical and mental health.

Non-Pharmacological Interventions for Reducing Fear and Anxiety in Patients Undergoing Third Molar Extraction under Local Anesthesia: Systematic Review and Meta-Analysis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph191811162. [PMID: 36141435 PMCID: PMC9517611 DOI: 10.3390/ijerph191811162] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/13/2022] [Revised: 08/31/2022] [Accepted: 09/03/2022] [Indexed: 05/17/2023]
Abstract
This report investigated the effectiveness of non-pharmacological interventions for reducing dental fear and anxiety in patients undergoing third molar extraction under local anesthesia. In November 2020, multiple electronic databases (Cochrane, EMBASE, MEDLINE, PsycInfo, PsycArticles, PubMed, and Web of Science) were searched for articles published in English. Inclusion criteria were randomized-controlled trials reporting the effectiveness of any non-pharmacological interventions in reducing fear or anxiety levels in patients with third molar extraction. A total of 3015 studies by electronic search and 2 studies by hand search were identified. After screening, 21 studies were eligible for systematic review. Seven studies were included in the meta-analysis. Study selection, data extraction, and quality assessment of the included studies were performed by two independent investigators. The anxiety levels after intervention in each study were pooled and meta-analyzed by the random-effect model. A significant reduction in anxiety level was observed in non-pharmacological intervention groups (SMD = -0.32; 95% CI -0.57 to -0.07; p = 0.01). Subgroup analyses showed that a significant anxiety reduction by non-pharmacological interventions could be demonstrated by pooled data from studies using psychometric assessments, but not from studies using physiological assessments. Non-pharmacological interventions appear to reduce fear and anxiety levels in patients undergoing third molar extraction under local anesthesia.

Abstract
Objectives: The aim of this prospective clinical study was to evaluate the effects of the menstrual cycle phases and aromatherapy on women's perception of orthodontic debonding pain.
Materials and Methods: The materials of our study were consisted of randomly selected 48 female patients (mean age:19.00±3.40). Four different study groups were performed. LA+; the patients in the luteal phase and received aromatherapy(n=12), LA-; the patients in the luteal phase and did not receive aromatherapy(n=13), FA+; the patients in the follicular phase and received aromatherapy(n=11), FA-; the patients in the follicular phase and did not receive aromatherapy(n=12). Debonding was performed and the pain experience for each tooth was scored by the patient on a visual analogue scale (VAS). Also, participants' general responses to pain were assessed with the Pain Catastrophizing Scale (PCS). The aromatherapy protocol was to inhale lavender oil from approximately 30 cm for 3 minutes, 3 minutes before debonding.
Results: It was found that the mean VAS scores were higher in the luteal phase than in the follicular phase, however this difference was not statistically significant. There was no statistically significant difference between the groups with and without aromatherapy in terms of VAS scores(P>0.05). The correlation between total PCS scores and total VAS scores was statistically significant (r=0.310, P

Abstract
Mood disorders, also often referred to as affective disorders, are a group of psychiatric illnesses that severely impact mood and its related functions. The high medical expenditures have placed a significant financial burden on patients and their families. Aromatherapy is an alternative and complementary treatment that utilizes essential oils (EOs) or volatile oils (VOs) to achieve major therapeutic goals. In general, EOs are volatile chemicals that enter the body primarily through skin absorption and/or nasal inhalation. In addition, they can work through oral administration. Inhalation aromatherapy has shown unique advantages for treating mood disorders, especially depression, anxiety and mental disorders such as sleep disorder, which have been validated over the last decade through clinical and animal studies. Accumulating evidence has shown that EOs or VOs can bypass the blood-brain barrier to target brain tissue through the nasal-brain pathway. Subsequently, they act on the cerebral cortex, thalamus, and limbic system in the brain to improve symptoms of anxiety, depression and improve sleep quality. Here, we review the natural aromatic plants’ volatiles or essential oils used commonly as adjuncts to manage mood disorders and illustrate the mechanisms of inhalation aromatherapy, and mainly summarized the application of transnasal inhalation aromatherapy in depression, anxiety, and sleep disorders. We conclude that aromatherapy does not cause side-effects, which is vastly different from commonly used psychotropic drugs. Inhalation aromatherapy via brain-targeted nasal delivery offers potentially efficacious treatment for mental disorders and merits further study.

Abstract
Background Aromatherapy has been proved to be effective in alleviating anxiety in practices and research. Recently, copaiba oil (CPO) is popular in the market and is recommended for anxiety relief in aromatherapy practice. However, relevant scientific research is still lacking. Methods A randomized controlled trial was designed to evaluate the anxiety-relieving effect of CPO inhalation in 22 adults. Jojoba oil was used as the control treatment. N-back and mental arithmetic tasks were used as stress stimulation. CPO or control intervention was carried out after the n-back training phase. The State-Trait Anxiety Inventory (STAI), EEG activities, physiological indexes including heart rate (HR), blood pressure (BP), blood oxygen saturation, and salivary cortisol were assessed in different phases of the experimental process. Results There was no significant difference in the change of HR and BP between the CPO and control groups before odor intervention. The S-AI scores of the CPO treated participants decreased after the n-back and mental arithmetic tests and were significantly lower than those of the participants who received control treatments. The HR and salivary cortisol of participants who received CPO intervention significantly decreased during the n-back and mental arithmetic tests. Furthermore, a remarkable decrease of beta wave activity was observed in the left midfrontal region (F3) when the participant received the CPO intervention. Conclusion The study's findings supported that the CPO odor showed beneficial effects on alleviating anxiety based on several indicators in subjective, physiological, and EEG measurements.

Abstract
The purpose of this study is to reveal the chemical and biochemical characteristics and the potential aromatherapy applications of the essential oil (EO) of Salvia officinalis (common sage) within a hospital environment. The chemical composition was determined by gas chromatography with mass spectrometry and ATR-FTIR spectroscopy. Three types of sage EOs were included in this study: two commercial oils and one oil obtained by in-house hydrodistillation. Based on the findings, these EOs were included in different chemotypes. The first two samples were similar to the most common chemotype (α-thujone > camphor > 1,8-cineole > β-thujone), while the in-house sage EO revealed a high content of 1,8-cineole, borneol, α-thujone, similar to the Dalmatian type. The latter sample was selected to be evaluated for its antioxidant and medical effects, as borneol, a bicyclic monoterpene, is known as a substance with anesthetic and analgesic effects in traditional Asian medicine. The study suggests that the antioxidant capacity of the sage EO is modest (33.61% and 84.50% inhibition was determined by DPPH and ABTS assays, respectively), but also that the inhalation of sage EO with high borneol content by hospitalized patients could improve these patients’ satisfaction.

Abstract
Pine is a familiar scent in domestic cleaning products, but how often do we relate it to its origins as an odour emanating from a tree? This article takes a sensory history approach to trace the late 19th century and early 20th century use of the pine forest as a therapeutic space, via the tuberculosis sanatoria to the use of pine scent in domestic disinfectant. By focusing on pine as experienced in this period as a microhistorical subject, this methodology will in turn allow for a detailed consideration of how historical context, and in particular medical conceptions and health concerns, can influence the creation of cultural memory. By following the trajectory of pine from its place in the forest to a commercial product used in the home, this will allow for an investigation at the intersection of environmental and medical histories and provide a framework for the consideration of the relationship of place to senses associated with concepts of health and well-being. As interest grows in the development of more effective sensory settings, in particular within healthcare, it also highlights the importance of considering the roles both cultural and personal memory play in response to various sensory stimuli.

Abstract
Anxiety is an adaptive emotional response to potentially threatening or dangerous situations; moderated by the sympathetic nervous system. Dental anxiety is common and presents before, during or after dental treatment. The physiological response includes an increase in heart rate, blood pressure, respiratory rate, and cardiac output. Consequently, extensive distress leads to avoidance of dental treatment and multiple failed appointments, impacting both oral and general health. Dental anxiety can generate a variety of negative consequences for both the dentist and the patient. Evidence-based strategies are essential for mitigating and relieving anxiety in the dental clinic. Psychotherapeutic behavioural strategies can modify the patient's experience through a minimally invasive approach with nil or negligible side effects, depending on patient characteristics, anxiety level and clinical situations. These therapies involve muscle relaxation, guided imagery, physiological monitoring, utilizing biofeedback, hypnosis, acupuncture, distraction and desensitization. Pharmacological intervention utilizes either relative analgesia (nitrous oxide), conscious intravenous sedation or oral sedation, which can have undesirable side effects, risks and contraindications. These modalities increase the cost and availability of dental treatment.

Abstract
BACKGROUND Central precocious puberty (CPP) is caused by early activation of the hypothalamic-pituitary-gonadal axis but its major cause remains unclear. Studies have indicated an association between chronic environmental exposure to endocrine-disrupting chemicals and pubertal onset. Essential oil is widely used in homes worldwide for relief of respiratory symptoms, stress, and/or sleep disturbance. METHODS To evaluate this association, we compared the hormone levels and timing of vaginal opening (VO) in female rats exposed to lavender oil (LO) through different routes (study groups: control, LO nasal spray [LS], and indoor exposure to LO [LE]) during the prepubertal period. The body weights of the animals were also compared every 3 days until the day of VO, at which time gonadotropin levels and internal organ weights were assessed. RESULTS The LS group showed early VO at 33.8 ± 1.8 days compared with the control (38.4 ± 2.9 days) and LE (36.6 ± 1.5 days) groups. Additionally, luteinizing hormone levels were significantly higher in the LE and LS groups than those in the control group. Body weights did not differ significantly among the groups. CONCLUSION Inhalation exposure to an exogenic simulant during the prepubertal period might trigger early pubertal onset in female rats. Further evaluation of exposure to other endocrine-disrupting chemicals capable of inducing CPP through the skin, orally, and/or nasally is warranted.

Abstract
Objective: This study compared the effectiveness of auditory distraction and brief relaxation therapy for reducing anxiety in patients undergoing tooth extraction. Methods: A non-blind, three-armed, randomized control trial was carried out. The targeted study population were patients who needed extraction of a non-restorable and non-mobile molar tooth. Eighty-six patients were recruited; the brief relaxation therapy and auditory distraction groups had 32 participants each, while 10 of the 22 participants in the control group were excluded due to missing data. The Hierarchical Anxiety Questionnaire was used to assess the anxiety level. The Mann–Whitney U or Kruskal–Wallis test was performed to compare means between the groups. The before and after comparisons in each group were carried out using the Wilcoxon Signed-Rank test. The alpha value was set at 0.05, and data were analyzed using SPSS version 24. Results: The mean anxiety score after brief relaxation therapy and auditory distraction had significantly decreased (p < 0.001). Although not significant (p = 0.13), there was a slight increase in the anxiety score of the study participants in the control group just before the extraction procedure. Brief relaxation therapy was significantly effective in reducing anxiety scores in comparison to the control group (MD = 5.87, 95% CI = 2.58, 9.17; p = 0.001), but auditory distraction was not (p = 0.14). Conclusion: Both auditory distraction and brief relaxation therapy were effective in reducing patient anxiety before a dental procedure. Furthermore, it would be interesting to learn if these findings remain consistent for more complex dental procedures, such as surgical removal of an impacted third molar.

Abstract
OBJECTIVE To determine the effect of inhalation aromatherapy on sedation level, analgesic dosage, and bispectral index (BIS) values during donor site dressing in patients with burns. METHODS This trial was conducted on 62 patients with burns requiring donor site dressing who were admitted to the Burn Center of Imam Reza Hospital, Mashhad, Iran. In the intervention group, the patients inhaled damask rose 40% and lavender 10% essential oils during donor site dressing change, whereas in the control group, the site was dressed using routine protocol. Sedatives and analgesics were prescribed until the levels of brain activity achieved light sedation. The brain activity and sedation levels were measured before and after the donor site dressings using the BIS. Data were analyzed using the analysis of covariance and the two-way analysis of variance with repeated measures. RESULTS All 62 patients completed the study. The required doses of ketamine (P < .001), fentanyl (P = .003), morphine (P < .001), and propofol (P < .001) were significantly lower in the intervention group. The BIS was also significantly lower in the intervention group (P < .001). Heart rate decreased significantly during the aromatherapy, as well as after analgesic and sedative consumption (P < .001). CONCLUSIONS The inhalation of damask rose and lavender essential oils is an effective intervention to reduce the doses of sedative and analgesic drugs administered as well as BIS during donor site dressing change in patients with burns.

Abstract
Sleep disorders are common among the general population and can generate health problems such as insomnia and anxiety. In addition to standard drugs and psychological interventions, there are different complementary plant-based therapies used to treat insomnia and anxiety. This review aimed to find and examine the most recent research on the use of herbal medicines for treating anxiety and insomnia as compiled from clinical trials, as well as to assess the safety and efficacy of these medicines and to elucidate their possible mechanisms of action. The process entailed a search of PubMed, Scopus, and the Cochrane Library databases from 2010 to 2020. The search terms included "sleep disorder", "insomnia", "sedative", "hypnotic", "anxiety", "anxiolytic", and "clinical trial", combined with the search terms "herbs" and "medicinal plants", in addition to individual herbal medicines by both their common and scientific names. This updated review, which focuses mainly on clinical trials, includes research on 23 medicinal plants and their combinations. Essential oils and their associations have also been reviewed. The efficacy of medicinal plants depends on treatment duration, types of study subjects, administration route, and treatment method. More clinical trials with an adequate, standardized design are necessary, as are more preclinical studies to continue studying the mechanisms of action. As a result of our work, we can conclude that the 3 plants with the most potential are valerian, passionflower, and ashwagandha, with the combination of valerian with hops and passionflower giving the best results in the clinical tests.

Abstract
Essential oils (EOs) are extracted from plants and contain active components with therapeutic effects. Evidence shows that various types of EOs have a wide range of health benefits. In our previous studies, the potential of lavender EO for prevention and even treatment of depression and anxiety symptoms was demonstrated. The favourable outcomes may be due to multiple mechanisms, including the regulation of monoamine level, the induction of neurotrophic factor expression, the regulation of the endocrine system and the promotion of neurogenesis. The molecules of EOs may reach the brain and exert an effect through two distinctive pathways, namely, the olfactory system and the respiratory system. After inhalation, the molecules of the EOs would either act directly on the olfactory mucosa or pass into the respiratory tract. These two delivery pathways suggest different underlying mechanisms of action. Different sets of responses would be triggered, such as increased neurogenesis, regulation of hormonal levels, activation of different brain regions, and alteration in blood biochemistry, which would ultimately affect both mood and emotion. In this review, we will discuss the clinical effects of EOs on mood regulation and emotional disturbances as well as the cellular and molecular mechanisms of action. Emphasis will be put on the interaction between the respiratory and central nervous system and the involved potential mechanisms. Further evidence is needed to support the use of EOs in the clinical treatment of mood disturbances. Exploration of the underlying mechanisms may provide insight into the future therapeutic use of EO components treatment of psychiatric and physical symptoms.

Abstract
Lavandula angustifolia Mill. (lavender) is an essential-oil-bearing plant in the Lamiaceae family. Volatile oil produced through the steam distillation of lavender was examined to establish the essential oil yield and aromatic profile from each portion of the plant-namely, the corolla, calyx, leaf, and whole flowering top. The resulting essential oils were analyzed by GC-FID and GC-MS. The different plant parts generally shared similar compounds but in varying relative percentages. Aromatic profiles of the whole flowering top and calyx were similar, with prominent compounds being linalool acetate (34.3%, 32.0%), linalool (26.5%, 32.9%), lavandulyl acetate (5.6%, 4.9%), terpinen-4-ol (5.3%, 7.0%), and (Z)-β-ocimene (4.5%, 5.4%), respectively. Aromatic profiles for the corolla and leaf were unique. Prominent aromatic compounds of the corolla included linalool acetate (18.4%), linalool (10.8%), epi-α-cadinol (10.0%), borneol (7.3%), and lavandulyl acetate (6.3%). Prominent aromatic compounds of the leaf included epi-α-cadinol (19.8%), γ-cadinene (11.0%), borneol (6.0%), caryophyllene oxide (4.9%), and bornyl acetate (4.8%). Complete profiles and essential oil yields of corolla, calyx, leaf, and whole flowering top were established. This study establishes the influence the corolla, calyx, and leaf exert on the aromatic profile of the whole flowering top and provides insight into authentication of lavender essential oil.

Abstract
Essential oils are being studied for more than 60 years, but a growing interest has emerged in the recent decades due to a desire for a rediscovery of natural remedies. Essential oils are known for millennia and, already in prehistoric times, they were used for medicinal and ritual purposes due to their therapeutic properties. Using a variety of methods refined over the centuries, essential oils are extracted from plant raw materials: the choice of the extraction method is decisive, since it determines the type, quantity, and stereochemical structure of the essential oil molecules. To these components belong all properties that make essential oils so interesting for pharmaceutical uses; the most investigated ones are antioxidant, anti-inflammatory, antimicrobial, wound-healing, and anxiolytic activities. However, the main limitations to their use are their hydrophobicity, instability, high volatility, and risk of toxicity. A successful strategy to overcome these limitations is the encapsulation within delivery systems, which enable the increase of essential oils bioavailability and improve their chemical stability, while reducing their volatility and toxicity. Among all the suitable platforms, our review focused on the lipid-based ones, in particular micro- and nanoemulsions, liposomes, solid lipid nanoparticles, and nanostructured lipid carriers.

Abstract
Introduction Dental fear or dental phobia is caused by previous unpleasant dental experiences and pain. It can result in delaying or avoiding dental visits. Most often it leads to individuals avoiding visiting the dentist until physical pain completely impairs the quality of life. Objectives Transcutaneous electrical nerve stimulation (TENS) is a method of pain relief involving the use of a mild electrical current. The main aim of this study was to examine whether the TENS device affects the reduction of anxiety and fear during dental procedures. Material and Methods The study was conducted on a sample of 125 respondents, aged 9-14 years. Statistical significance of differences between pre- and post-treatment results on all applied measuring instruments was verified by the t-test for dependent samples. The calculation was performed for all respondents and individually for the three observed groups. The Children`s Fear Survey Schedule – Dental Subscale test was used to assess anxiety and fear. Results The results on the CFSS-DS scale in all subjects did not differ statistically significantly before and after treatment (p > 0.05). The results on the CFSS-DS scale in subjects who received TENS were statistically significantly different before and after treatment (p < 0.01). The results on the CFSS-DS scale in subjects who received local anesthesia were statistically significantly different before and after treatment (p < 0.05). Conclusion The TENS device had an anxiolytic effect after the first visit.

Abstract
Background Due to the pandemic, there is a significant interest in the therapeutic resources linked to TCIM to support potentially therapeutic research and intervention in the management of Coronavirus - 19 (COVID-19). At the date of this evidence map´s publication, there is no evidence of specific treatments for COVID-19. This map organizes information about symptoms management (especially on dimensions related to mental health and mild viral respiratory infections, as well as immune system strengthening and antiviral activity). Method This evidence map applies methodology developed by Latin American and Caribbean Center on Health Sciences Information based on the 3iE evidence gap map. A search was performed in the Traditional, Complementary and Integrative Medicine Virtual Health Library and PubMed, using the MeSH and DeCS terms for respiratory viral diseases associated with epidemics, COVID-19 symptoms, relevant mental health topics, pharmacological and non-pharmacological interventions related to TCIM. Results For the map, 126 systematic reviews and controlled clinical studies were characterized, distributed in a matrix with 62 interventions (18 phytotherapy, 9 mind-body therapies, 11 traditional Chinese medicine, 7 homeopathic and anthroposophic dynamized medicines and 17 supplements), and 67 outcomes (14 immunological response, 23 mental health, 25 complementary clinical management of the infection and 5 other). Conclusion The map presents an overview of possible TCIM contributions to various dimensions of the COVID-19 pandemic, especially in the field of mental health, and it is directed to researchers and health professionals specialized in TCIM. Most of the antiviral activity outcomes described in this map refers to respiratory viruses in general, and not specifically to SARS-CoV-2 (Severe Acute Respiratory Syndrome CoronaVirus 2). This information may be useful to guide new research, but not necessarily to support a therapeutic recommendation. Finally, any suspicion of COVID-19 infection should follow the protocols recommended by the health authorities of each country/region.

Abstract
Aromatherapy with essential oils can be used to relieve children. The aim of this study was to evaluate the correlations between psychological and physiologic findings after lavender oil inhalation among children assigned to undergo tooth extraction. A total of 126 children aged between 6 and 12 years were enrolled in the study. The groups were randomly divided into control and lavender groups. The lavender group inhaled 100% lavender oil for 3 min before the interventions, the control group received no prior application. Psychological assessments were made using face image scale (FIS), Face, Legs, Activity, Cry, Consolability (FLACC) and Wong-Baker pain rating scale (WBS). Physiologic changes were assessed using vital signs evaluations. All parameters were noted prior to applications, after inhalation, anesthesia injection, and tooth extraction. The lavender group showed significant lower anxiety and pain scores after tooth extraction (p < 0.05). Significantly lower levels of blood pressures and a significant pulse rate drop were found after inhalation in the lavender group. A statistically significant increase in heart rate was observed after anesthesia injection and tooth extraction in the control group (p < 0.05).Conclusion: Lavender oil can be preferred as a treatment of choice in routine pediatric dentistry.Trial registration number: NCT04115891 (Lavender Oil Inhalation Help to Overcome Dental Anxiety Among Children)What is Known:• Dental anxiety is the most common factor that causes children to have difficulty with the dentist and their parents during treatment.• Aromatherapy with essential oils can be used to relieve children.What is New:• Aromatherapy with lavender oil relieves the child by reducing the level of anxiety and facilitates dental treatment.• During surgical procedures such as local anesthesia and tooth extraction, lavender oil inhalation decreases pain levels of children.

PubMed, EMBASE, CDSR, CENTRAL, CNKI and grey literature databases were searched from inception to 10 January 2020. Randomised controlled trials (RCTs) and quasi-randomised controlled trials (CCTs) that examined the effects of aromatherapy on dental anxiety, compare to either negative control (i.e. no aromatherapy) or other positive control approaches (e.g. music), were included. The risk of bias of the selected studies was evaluated using the Cochrane Collaboration's tool and ROBINS-I, while the certainty of evidence was assessed using GRADE. A narrative synthesis was performed, rather than meta-analysis, due to the high level of heterogeneity across studies. RESULTS Eleven RCTs and six CCTs were included. The risk of bias was identified as either high or unclear in RCTs, and moderate to serious in CCTs. Performance bias and detection bias were the most prevalent in RCTs, followed by selection bias and reporting bias. As to CCTs, greater risk of bias was found in the selection of participants into the study and in the measurement of outcomes. Based on the selected studies, the most commonly used aromatherapy for dental anxiety management was lavender fragrance, followed by orange. Compared to the negative control condition, aromatherapy might reduce the anxiety-related physiological parameters and psychometric rating, pain, and mood, alertness, and calmness compared to the negative control condition; and there might be no intergroup difference in such outcomes between aromatherapy and music. However, GRADEs of the relevant evidence were judged as low to very low. CONCLUSIONS Compared to the negative control condition, aromatherapy is more effective to reduce dental anxiety and has comparable effects on dental anxiety compared to music intervention; however, the certainty of evidence is relatively limited. Further high-quality randomised trials with robust study design and large sample size are warranted to confirm our findings and to confirm the role of aromatherapy in relieving dental anxiety.

Abstract
PURPOSE Although lavender is purported to possess anxiolytic and sedative properties and is often recommended for relieving anxiety, the efficacy of lavender has not been well established. Thus, this review aimed to evaluate the anxiolytic effects of lavender aromatherapy. METHODS Ten data bases were searched for studies published between 2000 and 2018. Randomized controlled trials investigating the anxiolytic effects of lavender aromatherapy with any type of application for persons with or without clinical anxiety were included. The outcome variables included self-rated anxiety, vital signs, and salivary cortisol and chromogranin A (CgA) levels. In the meta-analysis, standardized mean difference and 95% confidence interval were calculated as effect measures by applying the random effect model and inverse variance method. RESULTS Twenty-two trials met our inclusion criteria. Lavender aromatherapy was found to have favorable effects in relieving anxiety (Hedges' ĝ = -0.65; 95% CI, -0.84 to -0.46) and decreasing systolic blood pressure (ĝ = -0.22; 95% CI, -0.43 to -0.02), heart rate (ĝ = -0.53; 95% CI, -0.74 to -0.32), and salivary cortisol (ĝ = -1.29; 95% CI, -2.23 to -0.35) and CgA (ĝ = -2.29; 95% CI, -3.24 to -1.34) levels. However, the meta-analysis did not reveal any significant effects of lavender on diastolic blood pressure (effect size: -0.17; 95% CI, -0.37-0.04). CONCLUSION Aromatherapy using lavender oil might have favorable effects on anxiety and its physiological manifestations. Future studies are recommended with an emphasis on methodological quality. In nursing practice, it is suggested that lavender aromatherapy be included in programs intended to manage anxiety in patients across diverse healthcare settings.
