Thank you for your post its a really interesting topic for discussion. Regarding the use of essential oils, we recommend following the manufacturers directions regarding the correct use of the essential oil product and not to ingest any of these products. There is some great information on the the Memorial Sloan Kettering cancer centre website regarding aromatherapy that you may like to view, see link below
