We source wild-harvested Frankincense from Oman, Boswellia Sacra, and slow heat infuse the raw resin into olive oil. The end result is an amazingly fragrant, thick oil that retains all of Frankincense's legendary healing constituents. Processing the resin in this way is different from essential oil in that we don't lose the boswellic acid that doesn't transfer over with steam distillation into essential oil. Comes in 1 fl.oz. size.
