Aromatherapy Faqs

 

Aromatherapy is a form of alternative medicine that uses volatile liquid plant materials, known as essential oils (EOs), and other scented compounds from plants for the purpose of affecting a person's mood or health.

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. It has a particularly Western currency and persuasion. Medical treatment involving aromatic scents may exist outside of the West, but may or may not be included in the term 'aromatherapy'.

History

Aromatherapy has roots in antiquity with the use of aromatic oils. However, as currently defined, aromatherapy involves the use of distilled plant volatiles, a twentieth century innovation. The word, aromatherapy, was first used in the 1920s by French chemist René Maurice Gattefossé, who devoted his life to researching the healing properties of essential oils after a lucky accident in his perfume laboratory. In the accident, he set his arm on fire and thrust it into the nearest cold liquid, which happened to be a vat of lavender oil. Immediately he noticed surprising pain relief, and instead of requiring the extended healing process he had experienced during recovery from previous burns--which caused redness, heat, inflammation, blisters, and scarring--this burn healed remarkably quickly, with minimal discomfort and no scarring.

Main branches

The main branches of aromatherapy include:

  • Home aromatherapy (self treatment, perfume & cosmetic use)
  • Clinical aromatherapy (as part of pharmacology and pharmacotherapy)
  • Aromachology (the psychology of odors and their effects on the mind)

 

Materials

Some of the materials employed include:

  • Essential oils: Fragrant oils extracted from plants chiefly through distillation (e.g. eucalyptus oil) or expression (grapefruit oil). However, the term is also occasionally used to describe fragrant oils extracted from plant material by any solvent extraction.
  • Absolutes: Fragrant oils extracted primarily from flowers or delicate plant tissues through solvent or supercritical fluid extraction (e.g. rose absolute). The term is also used to describe oils extracted from fragrant butters, concretes, and enfleurage pommades using ethanol.
  • Phytoncides: Various volatile organic compounds from plants that kill microbes. Many terpene-based fragrant oils and sulfuric compounds from plants in the genus "Allium" are Phytoncides, though the latter are likely less commonly used in aromatherapy due to their disagreeable odors.
  • Herbal distillates or hydrosols: The aqueous by-products of the distillation process (e.g. rosewater). There are many herbs that are used to make herbal distillates and they have culinary uses, medicinal uses and skin care uses. Common herbal distillates are rose, lemon balm and chamomile.
  • Infusions: Aqueous extracts of various plant material (e.g. infusion of chamomile)
  • Carrier oils: Typically oily plant base triacylglycerides that are used to dilute essential oils for use on the skin (e.g. sweet almond oil)

 

Theory

Aromatherapy is the treatment or prevention of disease by use of 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.

In the English-speaking world, practitioners tend to emphasize the use of oils in massage. In the UK, America, and Australia, 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 anti-septic, antiviral, antifungal and antibacterial properties of oils in the control of infections is emphasized over the more "touchy feely" approaches familiar to English speakers. 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 oils are included in the national pharmacopeia, 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 (commonly in form of "massage oils" i.e. 1-10% solutions of EO in carrier oil) they activate thermal receptors, and kill microbes and fungi. Internal application of essential oil preparations (mainly in pharmacological drugs; generally not recommended for home use apart from dilution - 1-5% in fats or mineral oils, or hydrosoles) may stimulate the immune system.
