Aromatherapy facilitates healing through the use of essential oils. The chemical structure of essential oils can penetrate cell membranes and transport oxygen and nutrients into the cells. These oils nourish and replenish the muscle tissue and joints via the blood stream which in turn goes deep into all the organs and tissues. The oils can be used in a variety of ways: direct application, diluted in bath or shower gels or in a body lotion, used in dietary supplements, diffused into the air, or added to cleaning solutions.
