a carrier oil, or is it already mixed when you buy it? I mix Frankincense with sweet almond oil as a face cream, and it makes my skin feel wonderful. My mother mixes it with Noxema (because she had some and was out of carrier oils), and it helps her neuropathy a great deal. Never heard of that so it kinda scares me, but she is 91, if she can get relief from pain, that's great.
