Oil diffusers are a very interesting technology. You fill them essential oils diluted in water and they turn it into water vapor to then release into the air. Not only does this smell great but it is also proven that different essential oils have different medicinal effects. Therefore companies usually name the blends they in accordance with their benefits. A personal favorite brand of mine is the Canadian company Sage. Sage does a tremendous job and is an extremely trustworthy brand. They put 100% natural in their logo which guarantees legally that’s what their products need to be. This is a great statement because by law things that say they are all natural only actually have to be 17% natural.
