The therapeutic potential of essential oils, like other plant-derived remedies, has yet to be fully realized. Although numerous medical herbs have been utilized since antiquity, many of which have been exploited to provide the biologically active compounds which form the basis for most of our modern drugs (such as quinine and cocaine), there is still a great deal to be learnt about their precise pharmacology. This is particularly true of aromatic oils, which by their very nature have such a concentrated yet multifaceted make up. In addition, ‘only a small proportion of the world flora has been examined for pharmacologically active compounds, but with the ever-increasing danger of plants becoming extinct, there is a real risk that many important plant sources may be lost’.⁹

Modern research has largely confirmed the traditionally held beliefs regarding the therapeutic uses of particular plants, although with time the terminology has changed. A herb such as basil, at one time described as a ‘protection against evil’, or ‘good for the heart’ whose scent ‘taketh away sorrowfulness’, may in modern usage be described as an excellent prophylactic, nerve tonic and antidepressant. Like herbal remedies, an essential oil can cover a wide field of activities; indeed the same herb or oil (such as Melissa) can stimulate certain systems of the body while sedating or relaxing others. In order to gain a clearer understanding of the way essential oils work, and some of their particular areas of activity, it may be helpful to take an overall view of the systems of the human body.
