25 Benefits Of Essential Oil Diffusers (With Scientific References)

What are the benefits of essential oil diffusers? When you use an essential oil, you can either apply it topically if diluted with a carrier oil, add it to your bathwater, or include it in a tea. However, most essential oils are used in aromatherapy. This form of use requires the use of either a heated aromatherapy lamp or a diffuser.

When using the oils in a diffuser, follow the manufacturer’s recommendations for use. In most instances, you do not need to dilute the oil with a carrier oil or lipid. Most diffusers only require the use of water for dilution. The diffuser enhances the aromatic impact of an oil so it can heal or provide specific health benefits.
