Legend has it that in days of old, grave robbers allegedly used this blend to ward off germs and infection while robbing tombs of the riches that were buried with the dead. And if you google this blend by the copyrighted name, which I guess I cannot mention here, you can see all manner of petri dish studies that support the claim that this is a powerful, antiseptic and anti-bacterial combination. My blend is organic, and theirs is not. The essential oils are Clove, Lemon, Cinnamon Bark, Eucalyptus Globulus and Rosemary. You can diffuse this if you feel a cold or flu coming on, or use it in green cleaning products. You can also use it in a steam, but only a drop or 2 at a time. It is a wonderful and effective blend. However, I do not advise that you take this, or any other essential oil, internally. They are powerful and pure but they may not be safe to ingest in any quantity.
