What Does a Community Think About Aromatherapy?

The awareness and usage of aromatherapy applications are increasing day by day in society. The current study aims to evaluate the thoughts and attitudes of individuals toward aromatherapy in Türkiye and to determine factors affecting the use of aromatherapy. This community-based descriptive study is conducted throughout Türkiye. Nine hundred eighty-five questionnaires were suitable for data quality. SPSS 23.0 statistical package program was used, and the statistical significance level was accepted as P value of less than .05. Approximately 72.4% of the participants have heard of aromatherapy. The rate of hearing about the concept of aromatherapy was found to be statistically significantly higher among women (P = .000), those residing in a province/district (P = .011), and those working in an income-generating positions (P = .003). It was determined that 58.9% of the participants used any essential oil. The 5 most commonly used essential oils are lavender, tea tree, peppermint, rose, and thyme, respectively. The rate of essential oil use in women is higher than in men (P = .000). The conditions in which essential oils are most frequently used are to provide beauty to the skin (51.7%), skin diseases (51.0%), and respiratory tract diseases (46.0%), respectively. The most common sources of information about the essential oils used by the participants are the Internet/social media (57.6%) and pharmacists (53.4%). The results of this research revealed that the awareness and use of aromatherapy practice in the community are high according to the literature. Considering the high tendency to use these products among the public, physicians, pharmacists, and nurses must provide consultancy services on the use of these products.

Effects of aromatherapy on nausea and vomiting in patients with cancer: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: and purpose: Aromatherapy offers a low-risk solution for effectively managing common nausea and vomiting in cancer patients. This systematic review and meta-analysis aimed to assess its impact on these symptoms to facilitate practical guidelines establishment. METHODS: PubMed, Web of Science, Cochrane Library, MEDLINE, CINAHL, and Embase were searched for articles published until April 30, 2023. Inclusion criteria were randomized controlled trials (RCTs) on the effect of aromatherapy on nausea and vomiting in patients with cancer (age ≥18 years). The effect size was calculated using standardized mean differences (SMDs) with a random effects model. Subgroup analyses, meta-analysis of variance, and meta-regression were performed using the "meta" package in R version 4.0.2. Heterogeneity was assessed using I2 statistics. Sensitivity and publication bias analyses were performed; two reviewers independently assessed risk of bias using Cochrane's risk-of-bias tool 2.0. RESULTS: Twenty-five RCTs across 10 articles revealed that aromatherapy reduced overall nausea and vomiting in patients with cancer with significant efficacy (SMD = -0.81, 95 % confidence interval [CI]: -1.11 to -0.52). Furthermore, aromatherapy reduced nausea (SMD = -0.85, 95 % CI: -1.23 to -0.46) and combined nausea and vomiting (SMD = -1.08, 95 % CI: -1.68 to -0.47), but not vomiting alone (SMD = -0.24, 95 % CI: -1.03 to 0.55). Inhalation and massage yielded positive results, especially in chemotherapy-induced cases; peppermint oil was particularly successful. CONCLUSION: Our findings underscore aromatherapy's value in managing cancer treatment-associated nausea and vomiting. Conclusive evidence on aromatherapy-led nausea reduction is lacking due to limited RCTs; research is warranted for robust conclusions.

Effect of aromatherapy with peppermint essential oil on the gag reflex: a randomized, placebo-controlled, single-blind, crossover study.

BACKGROUND: Sensitive gag reflexes prevent dental patients from receiving appropriate treatment. Aromatherapy helps patients relax during dental procedures. However, the effect of aromatherapy on the gag reflex caused by the stimulation of the oral cavity is unknown. This study aimed to evaluate whether aromatherapy reduces gag reflexes during oral stimulation. METHODS: In this randomized, placebo-controlled, single-blind, crossover study, the gag reflexes of 24 healthy individuals (12 females and 12 males; mean age: 34.3 ± 9.5 years) were quantified. A standard saliva ejector was slowly guided down the participant's throat to determine the maximum tolerance of the gag reflex, and the insertion distance was measured to quantify the gag reflex. All individuals participated in an aromatherapy session with peppermint essential oil and a placebo session with distilled water. The gag reflex was quantified before (baseline) and after each session. Another measurement was performed using nitrous oxide/oxygen inhalation as a positive control. RESULTS: Gag reflex values significantly increased after aromatherapy with both peppermint essential oil and placebo compared to baseline values (paired t-test, P < 0.001 and P = 0.014, respectively). The gag reflex value also increased significantly during nitrous oxide/oxygen inhalation (paired t-test, P < 0.001). There was no significant difference in the increase rate of gag reflex values between the positive control and aromatherapy interventions, but it was significantly lower after the placebo intervention (repeated measures analysis of variance, P = 0.003; post-hoc test, P = 0.83 and P = 0.02). CONCLUSION: Aromatherapy with peppermint essential oil has the potential for reducing gag reflex during dental procedures. TRIAL REGISTRATION: The study was registered in the University hospital Medical Information Network Clinical Trials Registry under the code UMIN000050616 (approved 17/03/2023).

Effects of lavender essential oil inhalation aromatherapy on depression and sleep quality in stroke patients: A single-blind randomized controlled trial.

BACKGROUND AND PURPOSE: Post-stroke depression (PSD) has major implications for rehabilitation, motor recovery, activities of daily living, social and interpersonal functioning, and mortality. In view of the side effects of antidepressants, aromatherapy, a widely used non-pharmacological therapy, has received growing attention in recent years for its benefits of reduced complications, accessibility, and effectiveness. This study was designed to assess the effects of inhalation aromatherapy with lavender essential oil on depression and sleep quality in patients with PSD. MATERIALS AND METHODS: Forty patients with PSD were enrolled and randomized into experimental and placebo groups. Experimental-group patients inhaled microencapsulated lavender essential oil every night at bedtime over a period of 4 weeks. A nonwoven bag containing 2.3 g of microcapsules with about 1.5 g of lavender essential oil was placed on or under the patient's pillow, depending on the patient's scent sensitivity. Placebo-group patients used the empty nonwoven bags for the same period as the experimental group. The 17-item Hamilton Rating Scale for Depression (HAMD-17), the Zung Self-Rating Depression Scale (SDS), and the Pittsburgh Sleep Quality Index (PSQI) were used to measure outcomes. RESULTS: The HAMD-17 score, SDS score, and PSQI score showed statistically significant differences between both groups before and after intervention (P ≤ 0.01). The improvement in the experimental group was more marked than in the placebo group (P < 0.05). CONCLUSION: Lavender essential oil inhalation aromatherapy may help reduce depression and improve sleep quality in patients with PSD.

Effects of aromatherapy with Matricaria chamomile essential oil on anxiety and hemodynamic indices in patients with acute coronary syndrome, 2021: a randomized controlled trial.

BACKGROUND: Patients with Acute Coronary Syndrome (ACS) experience high levels of anxiety that may cause instability of hemodynamic indices, increased risk of ischemia, myocardial infarction and poor quality of life. Aromatherapy can affect patients' anxiety levels and improve hemodynamic indices. This study aimed to evaluate the efficacy of aromatherapy on anxiety and hemodynamic indices in ACS patients. METHODS: This study was a double-blind, randomized clinical trial conducted on 154 ACS patients. The participants were classified into two equal groups of intervention and placebo through the block randomization method. The data collection tools consisted of demographic information, a shortened 6-item version of the Spielberger questionnaire and a form of hemodynamic indices. For two consecutive nights, the intervention group inhaled 7 drops of the chamomile essential oil (%10) and the placebo group inhaled 7 drops of the sesame oil poured on a sterile cotton ball. The hemodynamic indices were collected half an hour before, one and four hours after the intervention until the next morning. The Spielberger questionnaire was completed once before the intervention and once after the end of the intervention, by the researcher through an interview. The number of heart rate (HR) was counted for a full minute. Also, the blood pressure (BP) of all the samples was measured by the researcher. Data analysis was done using Chi-square, paired t-test, and analysis of variance (ANOVA) in SPSS22. RESULTS: The mean and standard deviation of the age of patients were 58/2 ± 11.6 and 59.7% of them were female. The results of ANOVA showed a significantly lower anxiety score as well as systolic blood pressure (SBP), diastolic blood pressure (DBP) and HR in the intervention group compared to those of the placebo group (P < 0.001). The decrease in anxiety score after the intervention, in the intervention and placebo groups was (5.2 ± 1.9) and (1 ± 1. 18) respectively. In the intervention group, the SBP and DBP after the intervention, was significant (P < 0.05). Also, the HR was significant (P < 0.001) after the intervention. CONCLUSIONS: Aromatherapy could reduce anxiety and improve hemodynamic indices in ACS patients. TRIAL REGISTRATION: IRCT20080825001083N11.

Effects of Orange Oil Aromatherapy on Pain and Anxiety During Invasive Interventions in Patients With Hematopoietic Stem Cell Transplants.

Invasive interventions, such as peripheral intravenous cannula, port needle placement, and blood collection, are often required for both inpatient and outpatient follow-up patients with hematological malignancies and hematopoietic stem cell transplants. This prospective, randomized controlled experimental study assessed the effect of orange oil inhalation used in aromatherapy on pain and anxiety levels in invasive interventions with hematological malignancies and hematopoietic stem cell transplants. It was conducted prospectively with 80 patients with hematological malignancies who were treated in the adult bone marrow transplant unit and adult hematology service of a private hospital between May 2021 and April 2022. The orange oil inhalation used in aromatherapy was applied to patients in the intervention group. The Visual Analog Scale (VAS) and State-Trait Anxiety Inventory (STAI) were used for data collection. Regarding the personal characteristics of the patients, 42.5% were ≥61 years old, 60% were men, and 85% were married. VAS pain scores of the intervention group were statistically lower than those of the control group (P < .001). However, there was no statistically significant difference in the STAI scores of groups (P >.05). The study results show that orange oil inhalation has been determined to reduce pain during invasive interventions.

Smellscape as a healing factor in institutional gardens to enhance health and well-being for older people with dementia: A scoping review.

BACKGROUND: There is mounting evidence for the health benefits of aromatic scents for the older people with dementia. However, existing research has focused on indoor aromatherapy using essential oils. It is necessary to explore the health benefits of smellscapes in the outdoor environment for older people with dementia. AIMS AND OBJECTIVES: This scoping review aims to examine existing evidence for smellscape as a healing factor in institutional garden for older people with dementia, try to bridge the knowledge gaps between outdoor sensory garden scents and aromatherapy to develop green care techniques that incorporate outdoor activities. METHODS: Seven databases (Scopus, PubMed, PsycINFO, CINAHL, MEDLINE, Embase and Web of Science) were searched with English language articles published between 1990 and 2022. The PRISMA-ScR Checklist was used. RESULTS: Out of 1013 articles, 11 meet the inclusion criteria. The comprehensive health outcomes include five aspects: mental health; physical health; reduced agitation behaviour; improved cognitive function; and well-being. These aspects are part of the rehabilitation model comprising the person (older people with dementia), environment (garden smellscapes) and outdoor activities (active or passive interventions or a combination). CONCLUSIONS: The smellscape, as a healing factor in the garden, not only benefits from evidence on indoor aromatherapy but also creates a sensory environment for older people with dementia by compensating for functional impairment, activity support and environmental creation, thereby promoting enhanced health and well-being. RELEVANCE TO CLINICAL PRACTICE: The research on the healing effects of smellscapes presented in this review offers a novel environmental intervention technique for transferring evidence on essential oils to outdoor sensory gardens. This green care technique is suggested to assist in the creation of healing environments and interventions for people with dementia who cannot be cured. NO PATIENT OR PUBLIC CONTRIBUTION: This scoping review did not directly involve patient or public contributions to the manuscript.

Effects of aromatherapy on patient satisfaction with procedural abortion at less than 10 weeks' gestation: A randomized controlled trial.

OBJECTIVES: This study aimed to compare satisfaction with procedural abortion prior to 10 weeks' gestation in patients randomized to lavender essential oil aromatherapy vs placebo (jojoba oil). STUDY DESIGN: This randomized trial compared lavender aromatherapy vs placebo in patients undergoing procedural abortion <10 weeks' gestation. Participants self-administered and inhaled oil during their procedures. Our primary outcome was composite mean score on the Iowa Satisfaction with Anesthesia Scale. Participants completed the State-Trait Anxiety Inventory, a visual analog scale reporting maximum procedural pain, and reported postprocedure aromatherapy acceptability. RESULTS: We analyzed 112 participants randomized to aromatherapy (n = 57) vs placebo (n = 55). Baseline characteristics were similar between groups. We found no difference in overall satisfaction (mean Iowa Satisfaction with Anesthesia Scale scores aromatherapy: 0.72 ± 0.96 vs placebo: 0.46 ± 0.98, p = 0.17) or maximum procedural pain (median visual analog scale score aromatherapy: 65 [range: 4-95] vs placebo: 63 [range: 7-97], p = 0.91). Independent predictors of satisfaction included the use of oral sedation (B: 0.36; 95% CI: 0.04-0.69), state anxiety (B: -0.45; 95% CI: -0.79 to -0.10), and maximum procedural pain (B: -0.17; 95% CI: -0.25 to -0.09). The aromatherapy participants were significantly more likely to have found inhaling scented oil helpful during their procedure (71.9% vs 45.5%; p = 0.005) and would recommend it to a friend who needed a procedural abortion (86.0% vs 56.4%; p = 0.0005) compared to those in the placebo group. Additionally, patients in the aromatherapy group were significantly more likely to agree with the statement, "If I need another procedural abortion, I would want to inhale scented oil during my procedure" (87.7% vs 70.9%; p = 0.03). CONCLUSIONS: The adjunctive use of lavender aromatherapy during first-trimester procedural abortion does not improve satisfaction with anesthesia but is highly valued by patients. IMPLICATIONS: Oral opioids as an adjunct to standard analgesics during procedural abortion (ibuprofen and paracervical block) do not decrease pain, and nonopioid options are lacking. Given current limited anesthesia options, aromatherapy could serve as an affordable and acceptable nonopioid adjunct to current standard of care during procedural abortion.

Methyl eugenol aromatherapy: a delivery system facilitating the simultaneous application of male annihilation and sterile insect technique against the peach fruit fly.

BACKGROUND: The peach fruit fly, Bactrocera zonata (Saunders) (Diptera: Tephritidae) is an economically important polyphagous, quarantine pest endemic to South and South-East Asia. The male annihilation technique (MAT) and the sterile insect technique (SIT) are environmentally benign techniques used to suppress fruit fly populations on an area-wide basis. The MAT and SIT are typically used sequentially to avoid killing released sterile males; however, MAT and SIT potentially could be used simultaneously and thereby increase the overall efficiency of control programmes. Mating competitiveness of sterile males against wild counterparts is critical for the success of the SIT. Feeding on a semiochemical, methyl eugenol (ME) has been reported to enhance the male mating performance of many Bactrocera spp., including B. zonata, but its use in SIT operational programmes is limited owing to the absence of a viable delivery system. RESULTS: In the present study, we demonstrated that ME aromatherapy, a practical method for large-scale delivery of ME olfactorily, enhances the mating success of treated B. zonata males. ME aromatherapy application to 5-day-old immature males for a duration of 5 h resulted in increased mating success of males tested when sexually mature, compared to untreated males. The ME-aromatized males also exhibited reduced attraction to ME-lure. CONCLUSION: A practical delivery system for applying ME by aromatherapy to mass-reared males was developed. ME-aromatherapy enhanced male mating success and suppressed their subsequent attraction to ME, thus enabling the application of MAT and SIT at the same time. © 2023 Society of Chemical Industry.

Nonpharmacological Nursing Interventions in Postoperative Nausea and Vomiting: A Systematic Review.

PURPOSE: This study aims to assess the impact of nonpharmacological nursing interventions on postoperative nausea and vomiting (PONV). DESIGN: This is a systematic review. METHODS: MEDLINE, Web of Science, ScienceDirect, Tübitak-ULAKBIM, and TRDizin databases were searched for the following search terms, including "Postoperative Nausea and Vomiting," "Nurse," "Nursing," and "Nonpharmacological Interventions" to identify nonpharmacological nursing interventions for PONV. A systematic review of English and Turkish articles published in the period between January 1, 2012 and June 1, 2023 was conducted. The PICOT-SD method was used to determine the compatibility of the pieces with the eligibility criteria. FINDINGS: Fifty-eight of 3,874 articles obtained from databases fulfilled the eligibility criteria. This study demonstrated that acupuncture, aromatherapy, the oral intake of ginger, listening to music, education, and visits to patients decreased the incidence of nausea and vomiting and increased the quality of life. Additionally, it was found that patients' quality of life tended to improve along with reductions in postoperative complications. CONCLUSIONS: The results of this study support previous findings in the literature and demonstrate that nonpharmacological nursing interventions help reduce and prevent PONV. Based on our results, we suggest that nonpharmacological nursing interventions can be employed for the management of PONV in patients undergoing surgery.

Comparing the effect of aromatherapy with breast milk, Lavandula stoechas, and Rosa damascena on venipuncture pain in preterm infants.

INTRODUCTION AND OBJECTIVES: Since preterm infants frequently undergo painful diagnostic and therapeutic procedures, pain management, especially through non-pharmacological methods, will be extremely beneficial. Accordingly, the present study aimed to compare the effects of aromatherapy with breast milk, Lavandula stoechas, and Rosa damascena on venipuncture pain in preterm infants. METHODS: In this interventional study, preterm infants were randomly divided into four groups of aromatherapy with breast milk (25 infants), Lavandula stoechas (25 infants), Rosa damascena (25 infants), and sham (25 infants). One minute before, during, and two minutes after venipuncture, the Neonatal Infant Pain Scale (NIPS) as well as heart rate and SPO2 were measured. RESULTS: The results indicated that pain intensity was significantly lower during and after venipuncture in all the aromatherapy methods compared with the sham group (P < 0.001). Breast milk odor decreased the pain more than the other two odors during and after venipuncture (P < 0.001); however, there was no significant difference between Lavandula stoechas and Rosa damascena (P = 0.94). SPO2 was significantly higher in infants in the Lavandula stoechas (P < 0.001) and Rosa damascena (P = 0.03) groups compared with the sham infants. CONCLUSION: All three aromatherapy methods were effective in decreasing preterm infants' venipuncture pain. Since no study on the effect of aromatherapy with Rosa damascena was found in this regard, the effectiveness of aromatherapy with Rosa damascena is of great importance, and future studies are recommended to analyze this topic in greater depth.

An aromatherapy massage intervention on sleep in the ICU: A randomized controlled feasibility study.

We conducted a feasibility randomized controlled trial exploring the effect of aromatherapy massage on sleep in critically ill patients. Patients were randomized to receive aromatherapy massage or usual care, and feasibility of recruitment and outcome data completion was captured. Sleep (depth) was assessed through Bispectral Index monitoring and self/nurse-reported Richards-Campbell Sleep Questionnaires, and the Sleep in the ICU Questionnaire. Thirty-four patients participated: 17 were randomized to aromatherapy massage and 17 to control. Five participants who received the intervention completed outcomes for analysis (alongside eight controls). A larger study was deemed unfeasible in this population, highlighting the value of testing feasibility of complex interventions, such as massage for sleep in ICU.

The effect of Aromatherapy with Pelargonium graveolens (P. graveolens) on the fatigue and sleep quality of critical care nurses during the Covid-19 pandemic: A randomized controlled trial.

OBJECTIVES: Measures to reduce nurses' fatigue are necessary to improve the patient's care and the nurse's health and well-being. This study investigated the effectiveness of aromatherapy with Pelargonium graveolens (P. graveolens) essential oil on fatigue and sleep quality of nurses working in intensive care units (ICU). METHODS: In this double-blind, randomized, controlled clinical trial, 84 nurses working in the ICU of Covid-19 patients were assigned to two groups of P. graveolens and placebo by the stratified block method. The intervention group inhaled one drop of pure P. graveolens. The placebo group inhaled one drop of pure sunflower oil in three consecutive shifts (morning or evening) and each shift twice for 20 min. Using the Visual Analog Fatigue Scale (VAS-F), fatigue was measured 30 min before the intervention, immediately, and 60 min later. Also, on the morning of the intervention days, sleep quality was assessed with the Verran and Snyder-Halpern (VSH) Sleep Scale. Data analysis was performed using SPSS, version 24. Independent t-tests, Mann-Whitney, Chi-square tests, and MANOVA, were used. RESULTS: The mean score of fatigue immediately and 60 min after aromatherapy in the P. graveolens group was lower than in the control group (P Ë‚ 0.05). There was no significant difference between the mean sleep scores of nurses in the P. graveolens group before and after the intervention (P > 0.05). CONCLUSION: Inhalation aromatherapy with P. graveolens essential oil can reduce nurses' fatigue in the ICU. The findings of this study can make nurses interested in using aromatherapy as a self-care method.

The effect of rose oil aromatherapy and hand-holding on pain due to peripheral intravenous catheter insertion.

INTRODUCTION: The study aimed to evaluate the effectiveness of rose oil (Rosa Damascene Mill.) aromatherapy and hand-holding in reducing pain associated with peripheral intravenous catheter insertion. METHODS: A comparative mixed-method design. A total of 126 patients were included in the study. For the study's quantitative data, sociodemographic characteristics of the patients and the Patient Interview Form for the qualitative data of the Numeric Rating Scale were used. In all patients included in the study, PIVC insertion was performed a single time by the same nurse using a standard procedure. Chi-square and Bonferroni tests were used for comparative statistics. RESULTS: No statistically significant difference between the groups regarding age, gender, marital status, BMI, and education level (p>0.05). Pain scores: it was 2.40±1.78 in the rose oil group, 3.53±1.98 in the hand-holding group, and 4.88±1.56 in the control group. The difference between the groups regarding pain scores is statistically significant (p=0.001). CONCLUSIONS: The study determined that rose oil aromatherapy and hand-holding interventions reduce pain during PIVC. However, rose oil aromatherapy was more effective on pain than the hand-holding intervention. (Clinical Trial ID: NCT05425849).

[Storing Complementary Therapy Knowledge to Expand Nursing Roles].

Incorporating complementary therapy into nursing care is common in clinical practice. Complementary therapy is a non-pharmacological approach used to help address symptoms that cannot be alleviated entirely by medication. These complementary therapies often serve specific purposes, and nurses are the ideal candidates to administer them due to their patient care expertise. However, before applying any complementary therapy, it is essential to understand the potential medical safety, ethical, and legal considerations involved in the therapeutic process. Furthermore, administrators should strengthen their knowledge and implementation of these therapies to ensure safety during use. Complementary therapy facilitates the management of symptoms that are not manageable by medication alone. For example, aromatherapy and light therapy are employed in clinical settings to alleviate anxiety, depression, insomnia, and pain (Farrar & Farrar, 2020; Fong et al., 2023), while acupuncture, acupressure, and qigong are utilized to relieve pain in cancer patients (Behzadmehr et al., 2020). Although complementary therapy is gradually gaining acceptance in clinical practice for mitigating patient discomfort, it has yet to achieve widespread adoption, with the culture within healthcare institutions and the attitudes of healthcare professionals being significant factors influencing adoption willingness. Research findings indicate that the primary factor influencing the use of complementary therapy by nurses is lack of relevant knowledge (Siedlecki, 2021). Elements of complementary therapy have been incorporated into the blueprint of the National Council Licensure Examination - Registered Nurse in Western countries. Thus, nursing education programs in the United States are now required to integrate complementary therapy into their curricula (Helms, 2006). The above emphasizes the importance of equipping nursing professionals with crucial knowledge and skills related to complementary therapy. When integrated appropriately and safely into patient care, complementary therapy not only enhances the quality and status of nursing but also demonstrates the irreplaceable role of nurses in assisting patients manage symptoms that are not fully manageable by medication alone. As modern medical technology and treatment modalities continue to grow in complexity, nursing professionals must maintain an open-minded perspective and be willing to adapt to and learn the diverse knowledge and skills required in today's era of interdisciplinary. Implementing complementary therapy requires relevant healthcare knowledge for symptom relief as well as familiarity with the related principles and skills. Complementary therapy often involves more extended contact with the recipients of care, making it safer and more appropriate when administered by nursing professionals who have received medical training. In this column, three articles discuss common complementary therapeutic practices such as aromatherapy, the non-invasive Chinese medicine meridian-and-acupoint intervention, and light therapy. Each article introduces the principles of these therapies and their application in nursing. It is hoped that the information provided on these three complementary therapies will help nursing professionals find reference points for expanding and strengthening their interdisciplinary nursing practices. Thus, the inherent advantages of the nursing profession may be leveraged to further enhance and implement the professional nursing process and to maximize the roles and capabilities of the nursing profession.

[Clinical Applications of Aromatherapy].

Aromatherapy is a natural therapy that utilizes essential oils that enter the body through the skin, inhalation, or ingestion to promote health. Clinical aromatherapy refers to the incorporation of essential oils as a complementary therapy within the medical field and is conducted in accordance with medical safety, ethical, and regulatory requirements. Healthcare professionals must have a comprehensive understanding of clinical aromatherapy management and enhance their knowledge of aromatherapy. Based on a meta-analysis of the related literature, clinical aromatherapy management procedures and the various applications of aromatherapy for anxiety, depression, sleep disorders, and pain are introduced. The goal is to help appropriately integrate aromatherapy into the healthcare system to enhance quality of care and improve well-being in patients and healthcare providers.

The effect of lavender aroma for anxiety disorder: a study protocol for a multicenter, double-masked, randomized, placebo-controlled clinical trial.

BACKGROUND: Anxiety disorder is the most prevalent psychiatric disorder. Benzodiazepines, which are often used for anxiety in patients with anxiety disorder, have various side effects. Lavender, one of the most commonly used essential oils in aromatherapy, has the potential to reduce benzodiazepine use for anxiety disorders. METHODS: This study is a multicenter, double-masked, randomized, placebo-controlled clinical trial. The study will recruit patients aged 20-59 years old with generalized anxiety disorder and panic disorder among anxiety disorders. The bottle containing the test solution (lavender aroma essential oil or distilled water) will be given to the patients. Patients will carry the bottles with them in their daily life and use the drops on tissue paper when anxious. The primary endpoint is the number of times anxiolytics used in 28 days. DISCUSSION: If the use of benzodiazepines could be reduced by sniffing lavender aroma, which is inexpensive and safe, it would contribute not only to the risks associated with benzodiazepine use but also to the health care economy and could even be added as a standard treatment.
