Some biblical scholars try to seperate Frankincense from Olibanum when researching incenses of the Bible, and this is what causes many incense users confusion. The best of the research on this theme seems to indicate that the Olibanum of the Old Testament is in fact Boswellia Serrata, a close relative of Frankincense which mainly comes from a tree best known in India, but which also grows elsewhere. From our experiences with resins from around the world, this seems to make sense as the aroma of the various B. Serrata resins are distinct from the other specias of Frankincense trees. We follow this tradition, and therefore name all of the B. Serrataspecies "Olibanum", and the rest "Frankincense". Olibanum has a distinct Orange citrus aroma, both dark and heavy as in the African variety or light and clear as in best of the Indian variety.
