Essential oils that should generally be avoided for individuals with epilepsy include:

  • Rosemary oil: Contains camphor and 1,8-cineole, which may overstimulate the central nervous system and increase seizure risk.
  • Sage oil: Particularly common sage, contains thujone (a neurotoxin) that may trigger seizures.
  • Fennel oil: May disrupt nervous system balance, potentially raising seizure risk.
  • Eucalyptus oil: High levels of 1,8-cineole may increase neuronal excitability.
  • Peppermint oil: High menthol content may induce seizure symptoms in some individuals.
  • Camphor oil: Directly associated with neurotoxicity and easily provokes seizures.
  • Wintergreen oil: Contains methyl salicylate; high doses may irritate the nervous system.
  • Oregano oil: Potent compounds may excessively activate neural pathways.

General Recommendations: Individuals with epilepsy should avoid any essential oils that may stimulate the nervous system and consult a doctor or professional aromatherapist before trying aromatherapy to ensure safety.
