Background Essential oils (EOs) are widely used in cosmetics, perfumes, massage fluids, aroma therapy and natural medicine. Some EOs contain contact sensitizers. Objectives To describe the frequency of sensitization to EOs in dermatitis patients presenting in skin clinics including concomitant reactions, to evaluate the EO patch test preparations and to identify patient groups with an increased risk of EO sensitization. Patients and methods Retrospective analysis of data from the Information Network of Departments of Dermatology (IVDK), 2010–2019. Results Twelve EOs were patch tested in an aimed manner in 10 930 patients, of whom 908 (8.3%) reacted to at least 1 EO. Only 6 EOs elicited more than 1% positive patch test reactions: ylang ylang (I + II) oil (3.9%), lemongrass oil (2.6%), jasmine absolute (1.8%), sandalwood oil (1.8%), clove oil (1.6%) and neroli oil (1.1%). Concomitant reactions among EOs or to EOs and fragrances were frequent. Among EO‐positive patients, women, leg dermatitis patients, patients aged 40 years or more, masseurs and cosmeticians were over‐represented. Conclusions Sensitization to EOs occurs, albeit infrequently in most cases. Masseurs and cosmeticians have an increased risk of sensitization to EOs.

“…It should be noted that lavender (as food) is “generally recognized as safe” (GRAS) by the U.S. Food and Drug Administration; data about the excretion of its ingredients into breast milk is limited. However, there are some reports about minor and transient adverse events, some of them are occupation‐related (Navarro‐Trivino, Jadczak, & Ruiz‐Villaverde, 2020) and some in patients undergoing clinical trials (Malakouti, Jabbari, Jafarabadi, Javadzadeh, & Khalili, 2017).…”

Sleep disorders are one of the most prevalent psychiatric diseases. Insomnia is the most common sleep disorder amongst the general population. It is also one of the most frequent complaints in primary healthcare centers. Lavender is called "the broom of the brain" in different oriental traditional medicines. It is one of the most used plants for patients with sleep disorders. This study reviews what is currently known about the use of lavender for sleep disorders in patients with different diseases, from cancers and end-stage renal disease to neurological-psychiatric diseases (e.g., depression, dementia, and autism), respiratory, cardiac, and metabolic diseases.Additionally, its most used administration route is the inhalation of its essential oil (i.e., aromatherapy) alone or in combination by massage. Some limitations of the reviewed literature were discussed briefly. Overall, this critical review provides promising evidence of the lavender efficacy for sleep disorders in a wide variety of populations and diseases. However, further clinical studies with robust design and longer durations of intervention are necessary for more evidence-based judgment on its effect on sleep problems and to investigate its mechanism of action.

Contact sensitizations in massage therapists with occupational contact dermatitis: Patch test data of the Information Network of Departments of Dermatology, 2008–2020

et al. 2022

Background Massage therapists are particularly exposed to constituents of massage preparations, wet work and mechanical strain and therefore, at high risk to develop occupational dermatitis (OD). Objectives To describe the sensitization spectrum of massage therapists with OD. Patients and Methods In a retrospective study, patch test data of patients with OD (128 massage therapists and 24 374 patients working in other professions) collected by the Network of Departments of Dermatology (IVDK, 2008–2020) were analysed. Results Hand dermatitis (91.4%) and allergic contact dermatitis (34.4%) were common in massage therapists with OD. Most frequent were sensitizations to fragrances/essential oils which were found in 54 (42.2%) massage therapists and thus, more often than in other patients with OD. Concomitant positivity to several fragrances/essential oils was frequent. In 8 (14.8%) of the 54 massage therapists, sensitizations to fragrances/essential oils were not detected with the baseline series, but only with special fragrance series. Conclusions Allergic contact dermatitis is common in massage therapists with OD and is mainly caused by fragrances and essential oils. Hence, massage therapists should be aware of this risk. When OD is suspected, not only the baseline series, but also special fragrance series should be patch tested in this occupational group.
