Aromatherapy is a way to improve the quality of life on a physical, emotional and spiritual level. Aromatherapy is already a part of our lives, although we may not have associated the name with the experience. Everyone has emotional responses, both pleasant and unpleasant, to certain scents. The idea behind aromatherapy is, first, to find the scents, unique for each individual, that evoke positive sensory feelings and emotions; and then to introduce those scents into our everyday life to enhance well-being. Natural scents keep us connected to the earth, sparking memories and emotions.

Aromatherapy History

Aromatic medicine, the ancient beginnings of the art of aromatherapy, was recorded in both Egypt and India more than 4,000 years ago. The Egyptians used aromatic plants to create massage oils, medicines, embalming preparations, skin care products, fragrant perfumes and cosmetics. Plant aromatics were also utilized in India as part of the ancient medical practice known as Ayurveda. Many of these practices are still in existence today.

At the beginning of this century, particularly in France and England, a movement by noted doctors and scholars in the naturopathic and medical communities prompted a reawakening to the benefits of natural medicine and aromatherapy. Today in England and the United States, aromatherapy is a commonly accepted alternative medicine. In France, it is common to find doctors who practice aromatherapy, pharmacies that sell essential oils and health insurance companies that reimburse for treatments using these approaches.

The Practice of Aromatherapy

Aromatherapy uses pure essential oils, extracted from many parts of the plant (flower, leaf, resin, bark, root, twig, seed, berry, rind and rhizome) to relax, balance and rejuvenate body, mind and spirit. Aromatherapy is both an art and a science. Aroma therapists, armed with a technical understanding of an oil's constituents, artfully blend essential oils to produce new aromas.

The results of aromatherapy are very individual. While there is general agreement about the actions of certain oils, aromatherapy texts vary in their descriptions of the properties and characteristics of an essential oil. No two persons are affected by the same essential oil in exactly the same way. Even the same person can be affected differently by the same oil depending on surroundings, time of day or mood.

What are Essential Oils?

Essential oils are the highly concentrated, volatile, aromatic essences of plants. Scientists agree that essential oils may perform more than one function in living plants. In some cases they seem to be a part of the plant's immune system. In other cases they may simply be end-products of metabolism. Essential oils contain hundreds of organic constituents, including hormones, vitamins and other natural elements that work on many levels. They are 75 to 100 times more concentrated than the oils in dried herbs.

All the countries of the world provide essential oils, making aromatherapy a truly global therapy. The purest essential oils come from carefully cultivated and wild grown plants from climatic and geographic regions throughout the world. Information on specific essential oils can be found in the Essential Oil Directory.

Not all Oils are Created Equal

Some plants, like rose and jasmine, contain very little essential oil. Their important aromatic properties are extracted using a chemical solvent. The end product, known as an absolute, contains essential oil along with other plant constituents. Though not a true essential oil, absolutes are commonly used for fragrancing cosmetic products like fine perfumes.

There are also significant differences between synthetic fragrance oils (made possible by recent advances in chemistry) and pure essential oils. Synthetic fragrance oils are produced by blending aromatic chemicals primarily derived from coal tar. These oils may duplicate the smell of the pure botanical, but the complex chemical components of each essential oil created in nature determine its true aromatic benefits. While synthetic fragrance oils are not suitable for aromatherapy, they add an approximation of the natural scent to crafts, potpourri, soap and perfume at a fraction of the cost.

Aromatherapy practitioners need pure essential oils of the highest quality. Important criteria to consider when selecting essential oils include the following: 100 percent pure and natural, country of origin, growing season, extraction method (e.g., distillation, expression), plant part used and the reputation of the company providing the oils.

Gems of Nature

Pure essential oils, like precious jewelry or fine wine, are the gems of nature - the quintessential life force of aromatic plants, sometimes called the "soul" of the plant. People who truly appreciate the qualities of pure essential oils consider each drop a precious jewel to be savored, enjoyed and protected.

Essential oils absorb into the fluid surrounding the cells beneath the skin's surface for a variety of effects including deep cleansing, nourishing, rejuvenating and balancing. Essential oils also diffuse into the air to provide olfactory benefits like purifying, refreshing and relaxing.

The Nose Knows

We perceive odors through thousands of olfactory nerves in our nostrils, which contain bundles of highly sensitive nerve cells. Unlike other nerve cells, these cells regenerate every 30 to 40 days. Specific aromatic molecules of essential oils react with specific nerve receptors, which in turn trigger electrochemical impulses that are conducted directly into the brain.

Aromas are transmitted to the limbic system, a part of the brain which perceives and responds to memory, pleasure and emotions. Odor triggers the limbic system to release brain-affecting chemicals known as neurochemicals. Enkephalin reduces pain and creates a feeling of well-being. Endorphins also reduce pain and induce sexual feelings. Serotonin helps relax and calm. Because the olfactory nerves are a direct extension of the brain's limbic system, recognition of smell is relayed immediately, whereas recognition of taste, sound and touch is not as immediate.

The olfactory system of the human brain has a lock and key mechanism for remembering scents. This creates an individual perception of aroma, different preferences for scents and specific memory responses. The lock is the actual smell memory; the key is the scent which opens the mind to the memory. In aromatherapy, the brain responds to the aroma of an essential oil by retrieving a past memory associated with the aroma. If the aroma is unfamiliar, the brain creates a new memory response. The memory responses can be relaxing, balancing, energizing, uplifting, etc. The sense of smell has the longest recall of all senses, so we tend to retain memories associated with aromas for quite some time.

What are Aromatherapy Blends?

Once you're using pure essential oils, it's natural to try blends of different oils to enhance their aromas and achieve specific aromatherapy benefits, such as relaxation and mental clarity. A successful blend requires knowledge about the properties of essential oils and experience in balancing the different aromas to achieve the desired result.

Aura Cacia's unique essential oils blends have been created to help take the guesswork out of aromatherapy -- the blending has been done for you. Our blends are a combination of 100% pure essential oils working synergistically to provide specific aromatherapy benefits -- perfect for individuals new to aromatherapy, or those wanting the convenience and savings that pre-blended essential oils provide.

How are Aromatherapy Blends Used?

Use Aura Cacia essential oil blends anywhere you want to add a touch of scent:

  • Enhance your beauty care products -- just combine one to three drops of your favorite Aura Cacia blend with one teaspoon of unscented shampoo, conditioner or lotion.
  • Try your hand at perfumery. Dilute ten drops of an aromatherapy blend on one ounce of high-proof vodka.
  • Add two to three drops to the rinse water when hand-washing clothes.

Essential Oil Safety Tips

Essential oils are very concentrated, so it's important to handle them with care. Please read these cautions carefully.

  • Always read and follow all label warnings and cautions.
  • Keep oils tightly closed and out of the reach of children.
  • Never ingest essential oils.
  • Don't use undiluted oils on your skin. (Dilute with vegetable oils.)
  • Skin test oils before using. Dilute a small amount and apply to the skin on your inner arm. Do not use if redness or irritation occurs.
  • Keep oils away from eyes and mucous membranes.
  • If redness, burning, itching, or irritation occur, stop using oil immediately.
  • Avoid use of these oils during pregnancy: bitter almond, basil, clary sage, clove bud, hyssop, sweet fennel, juniper berry, marjoram, myrrh, peppermint, rose, rosemary, sage, thyme and wintergreen.
  • These oils can be especially irritating to the skin: allspice, bitter almond, basil, cinnamon leaf, cinnamon bark, clove bud, sweet fennel, fir needle, lemon, lemongrass, melissa, peppermint, tea tree, wintergreen.
  • Angelica and all citrus oils make the skin more sensitive to ultraviolet light. Do not go out into the sun with these oils on your skin.
  • Sweet fennel, hyssop, sage, and rosemary should not be used by anyone with epilepsy.
  • People with high blood pressure should avoid hyssop, rosemary, sage, and thyme.

Extraction Methods

To extract essential oils in the most effective manner, while preserving their therapeutic benefits, they are either distilled or expressed. The two methods are briefly explained below.

Distillation

Pure essential oils are most commonly extracted from plants through the process of steam distillation. In this process, steam is introduced into a distillation chamber which contains the plant material. The steam breaks down the plant tissue, causing it to release its essential oil in a vaporized form. The vaporized essences, along with the steam and other substances, pass into a pipe through cooling tanks. The vapors return to liquid form and are separated from the water and captured as pure essential plant oil.

Expression

Expression, also known as cold pressing, is done exclusively with citrus oils. In this method, the oil-containing outer layer of the fruit is pressed and filtered to yield pure essential oil.

It takes 50 pounds of eucalyptus, 150 pounds of lavender, 500 pounds of rosemary, 1,000 pounds of jasmine and over 2,000 pounds of rose to make a single pound of essential oil! The price of each essential oil is directly related to the amount of plant material needed for distillation.
