The Olfactory and Limbic Systems

Essential oils pass easily through our skin and cell membranes. They diffuse through the entire body within half an hour. They go directly to the brain through the olfactory bulb. The affect our feelings and thoughts because smell is our most emotional sense. Because of their complexity they can affect us in myriad ways.

The Myriad

With just a few drops diffused in the air or on the skin one essential oil can do so many different things all at once affecting a change physically, emotionally, and mentally.

The olfactory bulb carries molecules and impulses into the brain area where our emotional memory is stored.

Scent stimulates nerves to fire in the emotional center of the brain, but it also stimulates the master gland to release hormones. Hormones affect the fight or flight response, as well as digestion and heart rate. In this way, essential oils can affect us in many ways all at once, just through their fragrance.

But, essential oils also have a complex chemical structure, designed and produced by nature, which makes the use of essential oils uniquely economical and green for the environment. An oil like Lavender can be applied to a wound, on sore muscles, a broken bone, or a burn and will support the body’s natural self-healing process in all those areas. Or, it might stimulate the immune system or balance blood pressure, or relieve a tension headache, or help the body ease into a restful sleep.
