I used to burn this oil and it gave the room a lovely smell till I read that the fumes were not good!
I gradually stopped doing this also because a few times I forgot to refill the top part of the burner and the candle was burning and there was nothing to heat, so I figured it could be dangerous to do this.
I now have a patchouli one that I use as a perfume, though the other day when I got in the car, my kids all screamed at me because I "smellt" so strong! I can't smell it for more than a minute or two but I guess when you put it on, you get used to it...
I also put some in the bath tub when I have a bath which is infrequently, but it makes my skin lovely!
