It's funny that you mention making myrrh oil because I was looking up that very thing... :) The recipe for annointing oil piqued my interest & according to that recipe you need to soak the myrrh(among other things) in olive oil. one thing led to another and... Myrrh itself is a resin so I was curious as to how the oil is extracted...
It seems that myrrh is extracted through steam distillation. Here's a link on distilling essential oils:
Now, the process itself does not look to be that difficult. Myrrh is not expensive and is available from MountainRose herbs. But how MUCH myrrh is required to end up with a reasonable quantity of oil...?
HA! Just found the info...the yeild is 3-5% So that sounds as though you would have to have a decent quantity of myrrh...
