I work for a company with a division that makes essential oils. I would
recommend reading the label carefully. Many essential oils clearly state
"For external use only". There are ingredients that are not to be
ingested. If you are using peppermint oil- be sure it is pure &
specifically OK'd by the manufacturer for internal use/ingestion.
