There are 18 species of Frankincense Trees. You cannot just say Frankincense. You can say "Frankenstein", there was only one of him. You need to understand also each one has different therapeutic properties and also different chemical makeups. You can go back to my Frankincense page and read each one, I have a bunch on there and you can download the Frankincense Resins PDF that has all 18 of them there.
So please if you see it written anywhere as just Frankincense- tell the person or persons WHICH ONE YOU TALKING ABOUT?
