I’ve read that the more expensive the oil, the better the quality is supposed to be. But that can’t be a guarantee, can it?
I just don’t know if I can trust the label on the bottle that says 100% pure essential oil when i also read about companies that put synthetic stuff in their “pure” essential oils and sell them at an high price.
