Aromatherapy for All Levels: Using Diffusers
As the owner of an aromatherapy company, I get asked all the time: “How do I get started using essential oils? Well, one of the simplest and rewarding ways of doing this is getting into the “aroma” part of aromatherapy — the inhalation and enjoyment of the scent of the oils themselves. This in fact is a gateway to utilizing the whole realm of therapy available from pure essential oils. Once you get familiar with the oils and the way they smell by diffusing their aromas, you’ll be more apt to investigate the powerful medicinal aspects of aromatherapy and its many application techniques.
“Diffusing” an essential oil simply means evaporating it into the air. In aromatherapy, this most often implies the use of a tool or machines to more rapidly release the oil into your environment than if you just left a bottle open in the room or sprinkled a little oil the carpet. Now leaving a bottle open or sprinkling a little oil on a carpet is a perfectly good way of enjoying essential oils! But sometimes you’ll want the smell to be stronger, and for may therapeutic (health-supporting) applications, you’ll want a much higher concentration of essential oils in the air than these methods provide. Here’s where the diffusers come in.
All diffusers will improve the rate of evaporation of essential oils into your surrounding space. It is important to recognize that while this may use your oils faster, there are good reasons to do this: diffusing oils so they can be smelled over a much larger space; diffusing oils in a work environment to eliminate the scents of of other activities; and perhaps the most important is sometimes diffusing high concentrations of oils such that we can absorb more oils through our respiratory systems for our health. The least expensive diffusers will use a small heating element to evaporate the oils, or a small fan which moves air more quickly over the oils for the same effect. These are usually excellent choices for a small bedroom or office. A little more high-tech are the humidifying ultrasonic diffusers, which are actually just small ultrasonic humidifiers. They do a wonderful job in small to medium environments, particularly in dry climates or during the winter with forced-air heat systems.
There are other simple, inexpensive ‘low-tech’ methods of diffusing essential oils. These are as simple as candle warmers — where a candle gently evaporates a few drops of essential oil floating on a small bowl of water above a tea-light candle (don’t forget the water! So many people report these devices burn their oils, but they’ve put them just over the heat!). A Reed Diffuser is also common, which evaporates aromatic oils through bamboo reeds and slowly into the air. Though they do most often use a synthetic dispersion agent called DPG or dipropylene glycol, which most aromatherapists will not recommend using, as at some point the diffusion process requires one breathing in its vapors.
The high end of aromatherapy diffusers are called cold-air nebulizing diffusers. The use nothing but a pressurized stream of air to make a fine mist of essential oil, which then evaporates directly into the air. The best of these units have a variable output control so they can be properly adjusted to the size of the room and/or the desired concentration of aroma in the air. The nebulizing diffuser has the capability of both simply diffusing oils for their aromatic effects, and to go so far as to deliver true therapy in aroma medicine. The classic aroma medicine texts show images of people placed in oxygen-style tents inhaling significant quantities of essential oil vapor to cure them of very serious infectious diseases. This effect can be created in small rooms, though it is important to have the guidance of a natural health professional before including this modality in a treatment program for yourself or a loved one. At the same time, these techniques are very worthwhile investigating, and the curing of infectious illness is considered one of the most promising medical application of essential oil therapy.
The choice of oils you can use in a diffuser is even more diverse than the kinds of diffusers available. It is really best to start with your desired reason for diffusing oils, then select your oils following this guideline. For general use, Citrus oils are very lovely, and combine very well to make your own unique scents. Try Lemon, Lime, Bergamot, Orange and Grapefruit together for example. Or the “evegreen” oils all blend together well: Fir, Spruce, Pine and Juniper create a very welcoming and warm atmosphere. Floral oils can be easily blended too, as can the woods and the herbs. Once you venture outside of blending oils from the same family, you’ll want to pay a little closer attention to the ratios of each oil you use, as it’s easy to make odd smelling recipes if you just start putting in “a little of this and a little of that”! On can always use a single oil at any time, particularly if you really enjoy one, but in the long run, blends can often be more interesting to the advanced aromatherapy user.
Blend recipes can often be found that are made for specific therapeutic needs — though in many cases, a single oil is called for in a “therapy”. Sleep can be helped for many people through just diffusing a high quality French Lavender essential oil; Memory and concentration can be enhanced by cold pressed Lemon oil or a steam distilled wild Rosemary. Immune system support is often provided by many of the oils from herbs, such as Melissa (Lemon Balm), Hyssop (a highly-regarded anti-viral oil), and Eucalyptus Radiata (recently shown to improve the efficacy of our white blood cells in their immune system action). Without too much work, you can find the right oils for your needs, and blending needn’t be too precise for these actions from a diffuser (though you would want to take care to be more precise with other modalities, like topical application, and in extreme cases, oil ingestion with the guidance of a doctor).
So there is a primer on diffusing essential oils. To recap, first pick the diffuser style that will suit your needs, whether you’ll just like to smell the aromas in a smaller space, or diffuse significant quantities for health reasons. Next, you can blend one oil at a time (diffusers usually do not require one to clean them between oils, nor are the therapeutic effects significantly altered by this), by a pre-blended formula, or create your own diffuser mixture. Just be sure not to include any fixed or carrier oils for diffuser use (many massage formulas can be converted to diffuser use simply by removing the carrier oil). Start slowly, remembering that you’ll generally need less oil than you think to produce the effect you need. And welcome yourself to a whole new world of natural medicine!
