Ingestion Question
For humans, one drop of essential oil is roughly equivalent to 30 cups of tea. Because of this intense concentration, taking essential oils by mouth can overstimulate the phase I and II liver detoxification pathways and lead to liver damage. Ingest essential oils only under the direction of a trained physician. In France, a physician sends orders to a compounding pharmacy for internal (oral, rectal or vaginal) essential oil prescriptions. Usually physicians prescribe essential oils for a maximum of 14 days.
