Inhalation, application and bathing are the three main methods used to encourage the entry of essential oils into the body. When inhaled, the extremely volatile oils enter via the olfactory system, and permeation of the skin occurs when they are diluted and applied externally. By bathing in essential oils, we can inhale and absorb the oils through the skin simultaneously.

The effectiveness of aromatherapy has been supported by recent research. It appears that most essential oils are antiseptic and bactericidal to some degree, whist some even seem to be effective in fighting viral infection. On inhalation, essential oil molecules are received by receptor cells in the lining of the nose, which transmit signals to the brain. Electrochemical messages received by the olfactory centre in the brain then stimulate the release of powerful neuro-chemicals into the blood which will then be transported around the body. Molecules inhaled into the lungs may pass into the blood stream and be disseminated in the same way.

It is known that odors we smell have a significant impact on how we feel. In dealing with patients who have lost the sense of smell, doctors have found that a life without fragrance can lead to high incidence of psychiatric problems such as anxiety and depression. We have the capability to distinguish 10,000 different smells. It is believed that smells enter through cilia (the fine hairs lining the nose) to the limbic system, the part of the brain that controls our moods, emotions, memory and learning. Studies with brain wave frequency has shown that smelling lavender increases alpha waves in the back of the head, which are associated with relaxation

When rubbed or massaged into the skin, essential oils will permeate the pores and hair follicles. They are then pass into the tiny blood vessels by virtue of their molecular structure, and then travel around the body.

Once absorbed, the action of the oil depends upon its chemical constituents. Most essential oils are high in alcohols and esters, although a few contain a high concentration of phenols, aldehydes and ketones. The latter are powerful chemicals and their use should be avoided by all save the skilled professional.

Each essential oil contains more than 100 chemical components, which together exert a strong effect on the whole person. Depending on which component is predominating in an oil, the oil act differently. Some oil are relaxing, some soothes you down and  some relieve pain. There are oils such as lemon and lavender, which adapt to what our body needs. The mechanism in which these essential oils act on us is not very well understood. What is understood is that they affect our mind and emotions and leave no harmful residues.
