I myself have never used the raw material either. I usually use Dragon Blood incense. I've incooperated it into many of my practices.
It can be used for cleansing, protection, relaxation, and numerous other "light" or "good" things.
To me, it would only make sense that if the incense works for these things, so would oils, and the raw material.
For the leaves, you can wrap them around your wand (if you have one) and you can use it so that you have more "force" or "energy" behind the wand when using it for any of the puproses I've listed above.
