The primary characteristics of these oils are as carriers of nutrients for the body and as sources of oxygen for the tissues and organs. This has tremendous value in stimulating our immune system. It is well known that human tissues require a substantial concentration of oxygen for their health. The oxygen and other nutrients are carried efficiently by the oils assuring good nutrition and, consequently, better health of the body tissues. Oils may be administered in numerous ways.
Inhalation is the process most used.
As essential oils are inhaled, they make their way through the nasal passages by way of the nasal mucosa to the receptors of the brain or into the lungs where they are absorbed into the blood stream. One of the most effective ways of delivering the oils for inhalation is through diffusion. A diffusor is a mechanical device that breaks up the oil into tiny particles and distributes them into the air. For the lymphatic, circulatory, digestive, and urinary or water elimination systems, as well as the nervous and respiratory systems, oils may also be applied directly to the skin over an injured area requiring special support. Localized injuries of the skin, such as abrasions, lacerations, burns, scars, or infections also respond well to the direct application of oils such as lavender, chamomile, or melrose.
