* Essential oils are highly concentrated substances (in some cases they are even toxic), therefore they are not suitable for administering orally unless as part of a medical therapy, under the supervision of a professional. In some cases they must even be diluted for external use; never apply pure essential oils to the skin. They must never come into contact with the eyes as they can cause serious irritation.
