Essential oil related seizures (EORS): A multi-center prospective study on essential oils and seizures in adults

•Essential oil-related seizures (EORS) can result from exposure to pro-convulsant essential oils, especially those containing eucalyptus and camphor.•Topical application, inhalation, or ingestion of these pro-convulsant essential oils can trigger seizures in otherwise normal individuals (EOIS) or in patients with epilepsy/epilepsy syndromes (EOPS).•Physicians should enquire about the exposure to these essential oils in any form in all patients with the first episode of seizure or breakthrough seizure.•Identifying the true cause of seizure will prevent future recurrence and unnecessary antiepileptic drug therapy.
