This article presents the results of a study conducted to explore the role of aromatherapy in therapeutic practices in Algeria. The study used a targeted survey method involving health professionals and auxiliaries. The questionnaire used in the study was based on a review of the literature on aromatherapy, essential oils, therapeutic practices, alternative medicine, the toxicity of essential oils, regulations and the essential oils market. The questionnaire was distributed physically in the Algiers region and also shared online via Google Docs and social media platforms. The data collected was initially processed and analysed using Microsoft Excel 2019. The study was conducted over a one-month period, from 25 April to 25 May 2023, and included healthcare professionals and related persons residing and practising in Algeria. Inclusion criteria required individuals to meet at least one of the two conditions, while incomplete or incorrectly completed forms were excluded. The results of the study showed that a total of 170 responses were collected from healthcare professionals. The study focused on the awareness and use of herbal products, particularly essential oils, among survey participants. The study also examined the length of time essential oils were used, the indications for which they were used, and the side effects and adverse reactions reported. The results highlight the need to improve the scientific literature and remedy the shortage of experts in this field, which can have an impact on the validity and credibility of aromatherapy practices. The study also highlights the importance of education, training and regulation to ensure the safe and effective use of essential oils in a therapeutic context.
