Essential oils are extracted directly from the bark, flowers, fruit, leafs, seeds or roots of a plant or tree. Just one drop can have powerful health benefits.
They are typically created through the process of distillation, which separates the oil and water-based compounds of a plant by steaming.
When the aroma of an essential oil is inhaled, it travels via the olfactory nerves of the nose into the brain via electrical impulses.
The sense of smell is directly linked to the limbic brain-the emotional control center. Therefore we react very quickly to smell with feeling! We do not even have to think; Stress for instance, is relieved with smell, not by thinking!
Aromas also affect our hypothalamus which stimulates the production of our energy and growth hormones.
