You wont believe where the scent vanilla is derived from. Japenese rearchers in 2006 discovered that heating and pressuring cow dung for 1 hour would produce vanillin. A sweet smelling substitute for vanilla. Though they say that they do not use it in food, it is not restricted as such. Only mentioning that people would shy away from the idea of ingesting it. So when your hovering over your scented candles and wofting down all that toxic Paraben, remember that its laced with cow feces as well.
Stick with aroma therapy essential oils and a diffuser.
