Aromatherapy History

The history of aromatherapy tells that aromatic or essential oils have been used for thousands of years as stimulants or sedatives of the nervous system and as treatments for a wide range of other disorders.[1] They link it historically to the use of infused oils and unguents in the Bible and ancient Egypt,[1] remedies used throughout the Middle Ages and the Renaissance,[2] and the burning of aromatic plants in various primitive religious rites.

The current applications of aromatherapy did not come about until the early 20th century when the French chemist and perfumer Rene Gattefosse coined the term “aromatherapy” and published a book of that name in 1937.[2] Gattefosse proposed the use of aromatherapy to treat diseases in virtually every organ system, citing mostly anecdotal and case-based evidence.[2]

Although Gattefosse and his colleagues in France, Italy, and Germany studied the effects of aromatherapy for some 30 years, its use went out of fashion midcentury and was rediscovered by another Frenchman, a physician, Jean Valnet, in the latter part of the century.

Valnet published his book The Practice of Aromatherapy in 1982,[3] at which time the practice became more well-known in Britain and the United States. Through the 1980s and 1990s, as patients in Western countries became increasingly interested in complementary and alternative medicine (CAM) treatments, aromatherapy developed a following that continues to this day.

In addition to the growing use of essential oils by nurses and aromatherapy practitioners for specific medical issues, the popularity of aromatherapy has also been exploited by cosmetics companies that have created lines of essential oil–based (though often with a synthetic component) cosmetics and toiletries, claiming to improve mood and well-being in their users.

Despite the growing popularity of aromatherapy in the latter part of the 20th century (especially in the United Kingdom), not much research on the topic of aromatherapy was available in the English-language medical literature until the early 1990s or mid-1990s.

The research that began to appear in the 1990s was most often conducted by nurses, who tended to be the primary practitioners of aromatherapy in the United States and United Kingdom (although it is dispensed by medical doctors in France and Germany).

Aromatherapists now publish their own journal, the International Journal of Aromatherapy. Also, many studies regarding the effects of odor on the brain and other systems in animals and healthy humans have been published in the context of odor psychology, neurobiology and aromatherapy.

In addition to topical antibacterial uses,[4] aromatherapy has also been proposed for use in wound care [5] and to treat a variety of localized symptoms and illnesses such as alopecia, eczema, and pruritus.[6-10] Aromatherapy has also been studied via inhalation for airway reactivity.[11]

Studies on aromatherapy have examined a variety of other conditions: sedation and arousal;[12,13] startle reflex and reaction time;[14,15] psychological states such as mood, anxiety, and general sense of well-being;[16-31] neurologic impairment;[24] chronic renal failure;[25] agitation in patients with dementia;[32-36] smoking withdrawal symptoms;[37,38] postoperative nausea;[39] nausea and emesis in combination with fatigue, pain, and anxiety in patients in labor;[26,27,40] pain alone;[41-43] and pain in combination with other symptoms.[23,24,26,27]

Published articles have described the use of aromatherapy in specific hospital settings such as cancer wards, hospices, and other areas where patients are critically ill and require palliative care for pain, nausea, generalized stress, and anxiety.

These observational studies provide examples of the clinical uses of aromatherapy (and other CAM modalities). Subjects have included hospitalized children with HIV,[44] homebound patients with terminal disease,[45] and hospitalized patients with leukemia.[46] Studies of aromatherapy use with mental health patients have also been conducted.[47,48] Most of the resulting articles describe successful incorporation of aromatherapy into the treatment of these patients.

Theories about the mechanism of action of aromatherapy and essential oils differ, depending on the community studying them. Proponents of aromatherapy often cite the connection between olfaction and the limbic system in the brain as the basis for the effects of aromatherapy on mood and emotions; less is said about proposed mechanisms for its effects on other parts of the body.

Aromatherapists also believe that the effects of the treatments are based on the special nature of the essential oils used. Some authors propose that the extraction of essential oils from whole aromatic plants causes them to contain a life force or vitality that allegedly sets essential oils apart from other (synthetic) fragrances.[49] This argument suggests that essential oils produce effects on the body that are greater than the sum of the individual chemical components of the scents.
