THE NERVOUS SYSTEM

Essential oils can be easily absorbed through the skin and pass into the blood stream thus affecting the circulation. Oils which have a warming effect not only improve local circulation but also affect inner organs. These particular oils can ease local inflammation by releasing mediators in the body which cause blood vessels to expand, causing blood to flow more quickly and thus reducing swelling.
