Interaction with the human body
Essential oils re-establish the internal harmony and revitalise the functioning of internal organs that may be debilitated.
Depending on the type of application different essential oils operate in different ways.

Inhalation: when inhaled the essential oil vapours pass the mucous membrane where olfactory receptor cells process the chemical signals and send stimuli to the brain: the hypothalamus, the thalamus and amygdala. These stimuli have a kind of hormonal action that results in the release of neurochemical substances.
Massage, Bath, Compresses: When any one of these methods are used, the skin becomes the means of transmitting the essential oils. The skin is made up of 3 layers: the epidermis the dermis and hypodermis. The epidermis acts as a barrier to prevent penetration of the skin and protecting it from harm. Essential oils however can penetrate the skin and spread to the whole body via the blood system. Once in the body different essential oils will have a different effect on each organ.
