Aromatherapy

Aromatherapy is a generic term that refers to any of the various traditions that make use of essential oils sometimes in combination with other alternative medical practices and spiritual beliefs. Popular use of these products includes massaging products, medicine, or any topical application that incorporates the use of essential oils to their products. It has a particularly Western currency and persuasion. Medical treatment involving aromatic compounds may exist outside of the West, but may or may not be included in the term 'aromatherapy.

Aromatherapy is the treatment or prevention of disease by use of essential oils. Two basic mechanisms are offered to explain the purported effects. One is the influence of aroma on the brain, especially the limbic system through the olfactory system. The other is the direct pharmacological effects of the essential oils. While precise knowledge of the synergy between the body and aromatic oils is often claimed by aromatherapists, the efficacy of aromatherapy remains to be proven. However, some preliminary clinical studies show positive effects.

In the English-speaking world, practitioners tend to emphasize the use of oils in massage. Aromatherapy tends to be regarded as a complementary modality at best and a pseudoscientific fraud at worst.

On the continent, especially in France, where it originated, aromatherapy is incorporated into mainstream medicine. There, the use of the antiseptic, antiviral, antifungal, and antibacterial properties of oils in the control of infections is emphasized over the approaches familiar to North Americans. In France some essential oils are regulated as prescription drugs, and thus administered by a physician. French doctors use a technique called the aromatogram to guide their decision on which essential oil to use.

First the doctor cultures a sample of infected tissue or secretion from the patient. Next the growing culture is divided among Petri dishes supplied with agar. Each Petri dish is inoculated with a different essential oil to determine which have the most activity against the target strain of microorganism. The antiseptic activity manifests as a pattern of inhibited growth.

In many countries essential oil are included in the national pharmacopoeia, but up to the present moment aromatherapy as science has never been recognized as a valid branch of medicine in the United States, Russia, Germany, or Japan.

Essential oils, phytoncides and other natural VOCs work in different ways. At the scent level they activate the limbic system and emotional centers of the brain. When applied to the skin may stimulate the immune system.
