Encyclopedia of Essential Oils: The complete guide to the use of aromatic oils in aromatherapy, herbalism, health and well-being.. Julia Lawless
‘ladysmata’, solid unguents; ‘stymmata’, scented oils; and ‘diapasmata’, powdered perfumes. They were used to fragrance their hair, their bodies, their clothes and beds; large amounts of scented oil were used for massage after bathing. With the fall of the Roman Empire and the advent of Christianity, many of the Roman physicians fled to Constantinople taking the books of Galen, Hippocrates and Dioscorides with them. These great Graeco-Roman works were translated into Persian, Arabic and other languages, and at the end of the Byzantine Empire, their knowledge passed on to the Arab world. Europe, meanwhile, entered the so-called Dark Ages.
Between the seventh and thirteenth centuries the Arabs produced many great men of science, among them Avicenna (AD 980‒1037). This highly gifted physician and scholar wrote over a hundred books in his lifetime, one of which was devoted entirely to the flower most cherished by Islam, the rose. Among his discoveries, he has been credited with the invention of the refrigerated coil, a breakthrough in the art of distillation, which he used to produce pure essential oils and aromatic water. However, in 1975 Dr Paolo Rovesti led an archaeological expedition to Pakistan to investigate the ancient Indus Valley civilization. There, in the museum of Taxila at the foot of the Himalayas, he found a perfectly preserved distillation apparatus made of terracotta. The presence of perfume containers also exhibited in the museum dating from the same period, about 3000 BC, confirmed its use for the preparation of aromatic oils. This discovery suggests that the Arabs simply revived or improved upon a process that had been known for over 4000 years!
Rose water became one of the most popular scents and came to the West at the time of the Crusades, along with other exotic essences, and the method of distillation. By the thirteenth century, the ‘perfumes of Arabia’ were famous throughout Europe. During the Middle Ages, floors were strewn with aromatic plants and little herbal bouquets were carried as a protection against plague and other infectious diseases. Gradually the Europeans, lacking the gum-yielding trees of the Orient, began to experiment with their own native herbs such as lavender, sage and rosemary. By the sixteenth century lavender water and essential oils known as ‘chymical oils’ could be bought from the apothecary, and, following the invention of printing, the period 1470 to 1670 saw the publication of many herbals such as the Crete Herball published in 1526, some of which included illustrations of the retorts and stills used for the extraction of volatile oils.
In the hands of the philosophers, the art of distillation was employed in the practice of alchemy, the hermetic pursuit dedicated to the transformation of base metals into gold, the gross into the subtle. It was primarily a religious quest in which the various stages of the distillation process were equated with stages of an inner psychic transmutation, ‘dissolution and coagulation’: separation (black, lead), extraction (white, quicksilver), fusion (red, sulphur) and finally sublimation (gold or ‘lapis’). In the same way that aromatic material could be distilled to produce a pure and potent essence, so could the human emotions be refined and concentrated to reveal their valuable fruit, or true nature. In this context, volatile oils can be equated with the purified human psyche or ‘quintessence’ of the alchemists, being an emanation of matter and manifestation of spirit, mediator between the two realms.
Alchemy was the bridge across which the rich symbolism of the ancient world – Arab, Greek, Gnostic – was transported into our own era … thus symbolism fell from the rarefied heights into the melting-pot, and began to be tested in a continuous, dynamic interaction with the findings of chemistry.5
Throughout the Renaissance period, aromatic materials filled the pharmacopoeias which for many centuries remained the main protection against epidemics. Over the next few centuries the medicinal properties and applications of increasing numbers of new essential oils were analysed and recorded by the pharmacists. The list included both well-established aromatics such as cedar, cinnamon, frankincense, juniper, rose, rosemary, lavender and sage, but also essences like artemisia, cajeput, chervil, orange flower, valerian and pine.
The perfumery and distillation industries attracted illustrious names of the day and in the northern countries of Europe, especially at Grassein France, flourishing commercial enterprises sprang up. By the end of the seventeenth century, the profession of perfumery broke away from the allied fields, and a distinction was made between perfumes and the aromatics that had become the domain of the apothecary.
Alchemy gave way to technical chemistry, and with it went the interest in the inter-relatedness of matter and spirit, and the interdependence of medicine and psychology. There developed the idea of combating speculation with logic and deductive reason. With the scientific revolution of the early nineteenth century, chemists were able to identify for the first time the various constituents of the oils, and give them specific names such as ‘geraniol’, ‘citronellol’ and ‘cineol’. In the Yearbook of Pharmacy and Transactions of the British Pharmaceutical Conference in 1907, we find for example:
A pilea of undetermined botanical species has yielded a white essential oil with an odour of turpentine … A small amount of pinene was detected but its other constituents have not yet been identified. This oil is of interest as being the first instance of an essential oil derived from the family Uricaceae.6
It is ironic that this enthusiastic research laid the ground for the development of the oils’ synthetic counterparts, and the growth of the modern drug industry. Herbal medicine and aromatic remedies lost their credibility as methods of treatment went out of the hands of the individual and into those of professionals. By the middle of the twentieth century, the role of essential oils had been reduced almost entirely to their employment in perfumes, cosmetics and foodstuffs.
The term ‘aromatherapy’ was first coined in 1928 by Gattefossé, a French chemist working in his family’s perfumier business. He became fascinated with the therapeutic possibilities of the oils after discovering by accident that lavender was able to rapidly heal a severe burn on his hand and help prevent scarring. He also found that many of the essential oils were more effective in their totality than their synthetic substitutes or their isolated active ingredients. As early as 1904 Cuthbert Hall had shown that the antiseptic power of eucalyptus oil in its natural form was stronger than its isolated main active constituent, ‘eucalyptol’ or ‘cineol’.
Another French doctor and scientist, Dr Jean Valnet, used essential oils as part of his programme by which he was able to successfully treat specific medical and psychiatric disorders, the results of which were published in 1964 as Aromatherapie.
The work of Valnet was studied by Madame Marguerite Maury who applied his research to her beauty therapy, in which she aimed to revitalize her clients by creating a ‘strictly personal aromatic complex which she adapted to the subject’s temperament and particular health problems. Hence, going far beyond any simple aesthetic objective, perfumed essences when correctly selected, represent many medicinal agents.’7
In some respects, the word ‘aromatherapy’ can be misleading because it suggests that it is a form of healing which works exclusively through our sense of smell, and on the emotions. This is not the case for, apart from its scent, each essential oil has an individual combination of constituents which interacts with the body’s chemistry in a direct manner, which then in turn affects certain organs or systems as a whole. For example, when the oils are used externally in the form of a massage treatment, they are easily absorbed via the skin and transported throughout the body. This can be demonstrated by rubbing a clove of garlic on the soles of the feet; the volatile oil content will be taken into
