The Science

Aromatherapy may work by sending chemical messages to the part of the brain that affects moods and emotions. There are different theories about how aromatherapy and essential oils work. A leading theory is that smell receptors in the nose may respond to the smells of essential oils by sending chemical messages along nerve pathways to the brain's limbic system, which affects moods and emotions. 

Imaging studies and EEG studies in humans show that smells affect the limbic system and its emotional pathways. Behavior is affected by odors. In a recent study published in Nature, mice behavior is documented to be affected by odor.
