Perspectives on the use of aromatherapy from clinicians attending an integrative medicine continuing education event

Examining the benefits of extended patch test series in children: a comprehensive analysis

INTRODUCTION

The growing presence of allergens in materials and scarce data on allergic contact dermatitis in children has increased our need to refine its diagnosis in this population. We aimed to analyze children's specific responsivity to highly reactive subcomponents of Fragrance mix I, Fragrance mix II, and Textile dye mix from the European baseline series.

METHODS

We retrospectively analyzed patch test records of children aged 2 to 18 who underwent patch testing with the European baseline series between 2014 and 2022 in Israel.

RESULTS

A total of 367 children were included in the study. In all, 160 children had positive results; 43 patients reacted to one of the mixes, and 20 performed further testing. Eleven of them completed the extended series at the exact same times as the regular European series, which benefited children. Farnesol was the most reactive compound (30.8%).

CONCLUSIONS

Performing the extended European series provides a more accurate and time-efficient allergic contact dermatitis diagnosis. Farnesol reactivity appears prominent in children and may justify tighter product regulations.

Benefit of inhalation aromatherapy as a complementary treatment for stress and anxiety in a clinical setting – A systematic review

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.

Molecular Structure, Electronic Properties, Reactivity (ELF, LOL, and Fukui), and NCI-RDG Studies of the Binary Mixture of Water and Essential Oil of Phlomis bruguieri

Essential oils are volatile oil-like liquids with a characteristic strong smell and taste. They are formed in plants and are then extracted. Essential oils have extremely strong physiological and pharmacological properties, which are used in the medicine, cosmetics, and food industries. In this study, the molecules caryophyllene oxide, β-pinene, 1,8-cineol, α-cubebene, and β-caryophyllene, which are the molecules with the highest contents in the essential oil of the plant mentioned in the title, were selected and theoretical calculations describing their interactions with water were performed. Because oil–water mixtures are very important in biology and industry and are ubiquitous in nature, quantum chemical calculations for binary mixtures of water with caryophyllene oxide, β-pinene, 1,8-cineol, α-cubebene, and β-caryophyllene were performed using the density functional theory (DFT)/B3LYP method with a basis of 6–31 G (d, p). Molecular structures, HOMO–LUMO energies, electronic properties, reactivity (ELF, LOL, and Fukui), and NCI-RDG and molecular electrostatic potential (MEP) on surfaces of the main components of Phlomis bruguieri Desf. essential oil were calculated and described.

Salvia officinalis L. Essential Oil: Characterization, Antioxidant Properties, and the Effects of Aromatherapy in Adult Patients

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.

Pediatric healthcare professionals' perceptions, knowledge, and use of essential oils

OBJECTIVES

Complementary and Integrative Medicines (CIM) are widely used by adults and children. Despite this, studies have shown that Healthcare Professionals' (HCPs) views about CIM vary. Because underlying knowledge, perceptions and biases may influence HCPs' acceptance of a new aromatherapy program, the investigators sought to assess HCPs' views regarding aromatherapy before implementing an aromatherapy program in a pediatric hospital.

DESIGNS AND MEASURES

A convenience sample of HCPs at an academic pediatric hospital in the United States completed an investigator developed online questionnaire about their perceptions, knowledge, and use of essential oils.

RESULTS

The sample included 987 respondents, of which: 62.0% were nurses. Overall, 94.2% of HCPs indicated that they "rarely, never, or seldomly" discussed essential oil use with patients. Most indicated a willingness to incorporate essential oils into their patient care with appropriate education. Furthermore, 47.4% of HCPs reported positive views about the use of essential oils, 4.9% reported negative views and opinions, and 45% raised specific concerns about safety, education and/or evidence.

CONCLUSION

Overall, this study suggests that HCPs have limited knowledge regarding essential oils, are open to learning more about them, and would like more evidence specifically regarding the efficacy and safety of using essential oils in pediatrics. Additionally, most HCPs are not currently discussing essential oils with pediatric patients. However, they are open to incorporating them into their patients' care if they receive proper education, and are open to our organization implementing an aromatherapy program if appropriate education and safety measures are provided.

Aromatherapy for test anxiety in chiropractic students

OBJECTIVE

Up to 85% of college students experience test anxiety, which may contribute to decreased academic performance. The purpose of this study was to assess the feasibility of recruiting chiropractic students for a randomized trial involving aromatherapy for anxiety reduction.

METHODS

This study enrolled chiropractic students who were randomly assigned to separate rooms during a biochemistry test. Waterless diffusers dispersed a lemon and rosemary blend of essential oils in the experimental room and water in the control room. Students completed pretest surveys rating current and general anxiety. Posttest surveys included rating current anxiety. Analysis of covariance (ANCOVA) was preformed to determine within- and between-group differences for current anxiety. Feasibility was the primary aim, and the statistical significance of anxiety test scores between rooms was the secondary aim.

RESULTS

Sixty-four students were included in the study. The feasibility of research methods was noted for adherence to the study protocol (informed consent, randomization, and survey distribution and completion) and resource allocation. Design improvements are required in recruitment methods, follow-up surveys, and intervention blinding. ANCOVA for between-group comparisons showed no statistically significant difference between groups' pre- and posttest anxiety scores (p = .22). Two reported side effects, eye and sinus irritation, could not be attributed to treatment group. Most students were willing to use aromatherapy for test anxiety in the future.

CONCLUSION

We demonstrated feasibility in conducting a randomized study to measure the influence of aromatherapy on test anxiety in chiropractic students. A powered, randomized study is needed to determine if aromatherapy may be effective in reducing test anxiety.
