If for example, we have been working long hours at a desk and have developed a painful cramp in our neck, we should turn to the section on Circulation, Muscles and Joints where we find the heading ‘Muscular Cramp and Stiffness’. Of the essential oils which are listed, those shown in italics are generally considered to be the most useful and/or readily available, in this case allspice, lavender, marjoram, rosemary and black pepper. The choice of which oil to use depends on what is to hand, and on assessing the quality of each oil by consulting their entry in Part II of the book. Special attention should be paid to the safety data on each oil: both allspice and black pepper are known to be skin irritants if used in high concentration; rosemary and marjoram should be avoided during pregnancy; rosemary should not be used by epileptics at all. On the basis of our assessment, we may choose to use lavender, marjoram and a little black pepper which would make an excellent blend. Some of the principles behind blending oils can be found in Chapter 5, Creative Blending.
The various methods of application are indicated by the letters M, massage; C, compress; B, bath etc. Turn to Chapter 4, How to Use Essential Oils at Home, where you will find instructions on how to make up a massage oil or compress, and how many drops of oil to use in a bath. Further information on how essential oils work in specific cases can be found in Chapter 3, The Body – Actions and Applications.
3. Used as a comprehensive textbook, The Encyclopedia of Essential Oils provides a wealth of information about the essential oils themselves in all their various aspects, including their perfumery and flavouring applications. It shows the development of aromatics through history and the relationship between essential oils and other herbal products. It defines different kinds of aromatic materials and their methods of extraction, giving up-to-date areas of production. In addition, it includes information on their chemistry, pharmacology and safety levels. The ‘Actions’ ascribed to each plant refer either to the properties of the whole herb, or to parts of it, or to the essential oil. Difficult technical terms, mainly of a botanical or medical nature, are explained in the General Glossary at the end of the book.
However, since the therapeutic guidelines presented in the text are aimed primarily at the lay person without medical qualifications, the section dealing with the aromatherapy application of essential oils at home is limited to the treatment of common complaints only: Although there is a great deal of research being carried out at present into the potential uses of essential oils in the treatment of diseases such as cancer, AIDS and psychological disorders, these discussions fall beyond the scope of this book. References to the medical and folk use of particular plants in herbal medicine and their actions are intended to provide background information only, and are not intended as a guide for self-treatment.
When we peel an orange, walk through a rose garden or rub a sprig of lavender between our fingers, we are all aware of the special scent of that plant. But what exactly is it that we can smell? Generally speaking, it is essential oils which give spices and herbs their specific scent and flavour, flowers and fruit their perfume. The essential oil in the orange peel is not difficult to identify; it is found in such profusion that it actually squirts out when we peel it. The minute droplets of oil which are contained in tiny pockets or glandular cells in the outer peel are very volatile, that is, they easily evaporate, infusing the air with their characteristic aroma.

But not all plants contain essential or volatile oils in such profusion. The aromatic content in the flowers of the rose is so very small that it takes one ton of petals to produce 300g of rose oil. It is not fully understood why some plants contain essential oils and others not. It is clear that the aromatic quality of the oils plays a role in the attraction or repulsion of certain insects or animals. It has also been suggested that they play an important part in the transpiration and life processes of the plant itself, and as a protection against disease. They have been described as the ‘hormone’ or ‘life-blood’ of a plant, due to their highly concentrated and essential nature.
Aromatic oils can be found in all the various parts of a plant, including the seeds, bark, root, leaves, flowers, wood, balsam and resin. The bitter orange tree, for example, yields orange oil from the fruit peel, petitgrain from the leaves and twigs, and neroli oil from the orange blossoms. The clove tree produces different types of essential oil from its buds, stalks and leaves, whereas the Scotch pine yields distinct oils from its needles, wood and resin. The wide range of aromatic materials obtained from natural sources and the art of their extraction and use has developed slowly over the course of time, but its origins reach back to the very heart of the earliest civilizations.
Aromatic plants and oils have been used for thousands of years, as incense, perfumes and cosmetics and for their medical and culinary applications. Their ritual use constituted an integral part of the tradition in most early cultures, where their religious and therapeutic roles became inextricably intertwined. This type of practice is still in evidence: for example, in the East, sprigs of juniper are burnt in Tibetan temples as a form of purification; in the West, frankincense is used during the Roman Catholic mass.
In the ancient civilizations, perfumes were used as an expression of the animist and cosmic conceptions, responding above all to the exigencies of a cult … associated at first with theophanies and incantations, the perfumes made by fumigation, libation and ablution, grew directly out of the ritual, and became an element in the art of therapy.1
The Vedic literature of India dating from around 2000 BC, lists over 700 substances including cinnamon, spikenard, ginger, myrrh, coriander and sandalwood. But aromatics were considered to be more than just perfumes; in the Indo-Aryan tongue, ‘atar’ means smoke, wind, odour and essence, and the Rig Veda codifies their use for both liturgical and therapeutic purposes. The manner in which it is written reflects a spiritual and philosophical outlook, in which humanity is seen as a part of nature, and the handling of herbs as a sacred task: ‘Simples, you who have existed for so long, even before the Gods were born, I want to understand
