The Neuroscience of Essential Oils：

Restoring and rebuilding the olfactory brain architecture.

Essential oils - the kind used by aromatherapists to improve emotional and physical wellbeing - are extracted from plants using a variety of processes that produce an aromatic oil. They are highly concentrated and made up of hundreds of aromatic molecules that are perceived by our olfactory nerve as we use our sense of smell.

Our sense of smell plays a vital role in the physiological effects of mood, stress, and working capacity, and electrophysiological studies using an electroencephalograph (EEG) have shown that various fragrances affect spontaneous brain activities and cognitive functions, as well as influencing physiological functions.
