ABSTRACT
OBJECTIVES: Non-conventional medicines are not devoid of toxicity and it is relevant to establish an inventory of the general public's knowledge of essential oils. The objective is to identify the profile of the victims of a poisoning, the ways of administration and the symptoms as well as the incriminated essential oils. METHODS: Two surveys, for the general public and health professional, were distributed (January-March 2019). In addition, data from the Angers poison control center for the period 2017-2018 were analyzed and compared with the data from our study. RESULTS: Our surveys gathered 623 and 59 answers. The data of the poison control center of Angers counted 741 intoxications. The precautions for use and contra-indications of essential oils are not well known since 5% of the respondents identified them correctly. Our data show that using a mixture increases the risk of intoxication (P<0.02). The most cited essential oils in case of intoxication are Eucalyptus, Tea tree and Lavender. The symptoms mainly concern a cutaneous application (75%) and remain of short duration and without gravity. Concerning the intoxications referenced to the poison control center in Angers, the same essential oils are involved, the oral route is mostly used (70%) and the symptoms listed for 74% of intoxications concern oropharyngeal, ocular, abdominal and skin pain. CONCLUSION: The delivery of essential oils is not harmless and the data obtained both through our surveys and the processing of data from the poison control center of Angers show that they must be used with caution.
