subject: Practical Aromatherapy - The Easy Magic Of Diffusing Essential Oils [print this page] Essential oils are fast becoming recognized as something more than just natural perfumes. Some of their proven major therapeutic actions include direct eradication of bacteria and viruses, boosting immune system function, and acting to reduce stress, uplift spirits and improve rest. The reason these effects are mentioned specifically is that they're very easy to produce in your own home using one simple device, an "essential oil diffuser." A diffuser disperses essential oils in the air in your home or office, allowing you and your family to easily inhale the oils (for immune boosting, stress relief, etc.) AND naturally, effectively disinfecting the air.
The Data Is In: The Science of Aroma Medicine
The body of research revealing the diverse therapeutic and medicinal actions of essential oils has grown exponentially in the last several years. Research abstracts (summaries of investigations) are freely available through the online database maintained by the National Institute of Health. Many essential oils have been shown to be antidepressants, stress-relieving, and sleep-improving. Other oils have been shown to be potent airborne antibacterial agents, while others have the ability to destroy live viruses. Some of these same oils actually improve the function of our immune system, and some can change our cells in such a way to make them more resistant to viral infection. ALL these benefits can be had by evaporating various concentrations of essential oils in your environment by using a diffuser. Essential oil diffusers do come in many styles, and some are better suited to certain applications than others. Here's a review of the diffuser styles available to help you make the best choice for your needs.
Diffusers For Antiviral/Antimicrobial Action & Immune Support
In order to best disinfect the air in your surroundings, you can imagine you'd need a little bit more essential oil than what evaporates from an aromatherapy candle. To get this amount of output requires a "nebulizing" diffuser. To "nebulize" an essential oil means to make a very fine mist, which quickly and easily evaporates. Some diffuser manufacturers claim their diffusers make smaller droplets of mist than others, but the truth is they all will work. The droplets all "disappear" completely upon leaving the diffuser, without any residue around the machine. To best conserve your oils while still creating these therapeutic effects, you'll want a timer system too -- some come with them built-in, though the most versatile will be external, fully-programmable timers you can find online or in a hardware store.
Even the nebulizing diffusers come in a couple styles: Ultrasonic or Cold Air. The ultrasonic is a small ultrasonic humidifier, which makes a mist of cool water and essential oil together. The cold air style make a mist of only the essential oil, and of all the diffuser styles can output the highest concentration. Both these styles are regulated, allowing you to set the output to suit the size of your space and your therapeutic needs.
Diffusers for "Aroma"therapy: Anti-Stress and Emotional Support
Other styles of diffusers either gently warm the oils or use a fan to blow over the oils to evaporate them. Their intention is to get the oils in the air so you can enjoy their aromas -- and while this sounds simple, its actually therapeutically meaningful: The "smell sense" is the only one of the five senses directly wired to the control center of the brain (signals from the other senses travel through "switching stations" first). The result is that the body reacts to a smell without us thinking about it. Certain smells can lower blood pressure, slow heart rate, and help us sleep more deeply. Some users report feeling happier or calmer when inhaling particular scents, and other scents make the mind sharper -- improving test scores, reducing errors at work, and improving the efficiency of studying for school. A fan diffuser will blow air and evaporate oil from a cotton pad, and warming diffusers will safely (i.e. ok to use around children) and gently use heat to also evaporate oils from a pad. Both these styles are good choices for smaller areas, like a bedroom or living room.
Use Oils Efficiently with a Timer
The best way to use the least amount of essential oil for your needs is to use a timer -- either built-in to the diffuser or a readily-available appliance timer. For ANY application, whether simple aromatic use or medicinal needs, one need only be exposed to the diffused oils for a few minutes at a time. Aromatically, your "smell scent" will become quickly accustom to the aroma, and you'll start to think the diffuser isn't working anymore. Running the diffuser for only a few minutes every half an hour lets your nose "forget" the oils are in the air. The same principal works for disinfecting the air and immune-system support -- there's no need to over-saturate the air with essential oils. They are so potent that there's no need to continually diffuse a high concentration for these results.
Selecting The Best Oils For Your Needs
Each essential oil has a unique chemistry; the unique chemistry of each oil gives it its aroma and its therapeutic action. For emotional support -- oils that make you happy -- consider the "Needle" oils. Oils distilled from Spruce, Fir, and Pine needles are very popular to give your home the scent of being deep in the forest. You can imagine how pleasant that may be! Other anti-depressant oils include the citrus oils (virtually all the oils pressed from the peels of citrus fruit are considered very uplifting) and some folks really enjoy the florals: Rose Geranium, Rose, and Neroli. Lavender essential oil is THE most studied oil for calming and rest. There are many resources on the internet to help you find the oils you enjoy smelling, with the psychological energetic profile you're interested in. Most oils in this category are safe for all ages -- only Peppermint, used for invigorating mental activity, is not recommended for use with younger children.
For immune support and air-cleaning, there are many oils highly regarded for their antimicrobial actions. Bay laurel is very nice, and scientifically shown to be an effective anti-viral. "Plain" Lemon and Rosemary oils are excellent antibacterials, as is Lemon Tea Tree (very potent), Lemongrass, and Eucalyptus Radiata (shown specifically to help our white blood cells function better). Most oils that are sharper and brighter will be effective, but be careful as there are some herb-oils that are too strong to diffuse, like Oregano and Thyme, along with the spice oil Cinnamon. In any case, use your judgment with the aromas: if they seem to intense, they are -- and either switch to a different oil or turn down the diffuser output. Also be aware that children are MUCH more sensitive to essential oils than adults -- adjust your use as necessary, and consult a reputable guide to using essential oils with children.
In Conclusion: Diffusers Make Aroma-Therapy Simple
Essential oil diffusers are inexpensive and easily purchased at a local health food store and around the internet. Look for a unit specifically designed for use with pure essential oils, rather than "fragrance oils" (man-made replicates of natural scents -- there is no "pumpkin pie" essential oil, for example!). If you're not sure which oils to start with, there are many guides and great books available, and many aromatherapy companies will have support staff to help get you started. The world of aroma-medicine is available to you, and diffusing oils in your home is a great beginning in this realm of natural medicine.
