If there was one and only one essential oil I was allowed to use, it
would be frankincense, which comes from the Boswellia sacra tree. The
essential oil of kings!
Tree shepherds indeed!! For thousands of years, passed from generation to generation, the frankincense trees of the southern Arabian desert have been cultivated and harvested in order to produce this oil of kings. Sadly, today frankincense has gone on the endangered species list and thus the essential oil is becoming far more expensive and much more difficult to acquire.
