The science of aromatherapy is the study of essential oils, a scientific field that uses a rigorous methodology and is based on concrete scientific theory, confirmed by laboratory testing. The intimate relation that unites chemical structure with essential oils constitutes the foundation of scientific aromatherapy. The standards for essential oils must be established in conjunction with their impact on the ideal chemical composition and fullness of their essences, as designed by nature. One of the criterion of an essential oil is the care invested in its extraction.
