One of the easiest and most effective ways to use essential oils is in an ultrasonic diffuser which diffuses the oils in a cool mist right into the air. If you go online and start looking for one of these diffusers you will be inundated with an endless supply of options made with many different materials, with different lighting options, in different sizes and from the very cheap to the extravagantly expensive. So how do you decide what is the best option? In our last post Kay discussed the benefits and precautions around diffusing and these are all good things to keep in mind. While most manufacturers will boast of the run-time on their diffusers, saying things like 10 HOURS OF CONTINUOUS DIFFUSION, we know that this is not ideal at all. In order to prevent over saturation of the olfactory system and habituation to the scent we should not diffuse for more that an hour at a time. For longer periods using less essential oils and an intermittent diffuser that cycles on and off for at least 30 minutes is ideal.
When we first started using essential oils I received a diffuser as a gift, and it worked fine but as mom started her journey to become a Certified Aromatherapist and shared what she was learning with me I found myself using it less and less. Why? Honestly it’s because I was to lazy to turn it on and off! I would tell myself to turn it off after half an hour and then forget, or not want to get up from where I was ensconced under piles of grading or cuddled up with a good book. Who cares that the diffuser was just a few steps away, I just didn’t want to bother. So I stopped using it. A few months ago I started searching for a diffuser that had an intermittent cycle so that I could use it without worrying about keeping track of time or disrupting my grading flow and I was surprised at just how difficult it was to find one! Most manufacturers are just trying to extend the diffusion time, they don’t seem concerned about the safest and most effective use of the oils, and likely they just don’t know. Some do have what they call an ‘intermittent setting’ but it is only 30 seconds on and off which is not what we want.
Plant Therapy has their AromaFuse diffuser which has 30 minute intermittent cycle, but it’s more than $50… And that is more than I am willing to spend, especially since my old one still technically worked. Finally, after ages of combing through the descriptions of diffusers on Amazon I found the LED Concepts ultrasonic diffuser which, unfortunately, is now unavailable.
Update: We have not been able to locate a source for a 30 minutes on and a 30 minutes off intermittent misting ultrasonic diffuser other than the Plant Therapy Aromafuse. There are however a few that have 30 minute shut off timers. The following is a list of a few of the models that we found.
Essential oils can be used topically on the skin or by breathing them in. Topical application is most effective for skin conditions, muscles and joints. When addressing goals for emotional, nervous system, cognitive, and respiratory system balance the most beneficial way to use essential oils is by inhalation. It is not necessary to dilute them with a carrier oil when using them for different methods of inhalation.
Inhalation of essential oils utilizes the sense of smell to exert an influence on emotions, mood, concentration, sleep, memory, behavior and perception. Olfaction has the greatest impact on the regulation of these states of mind because the olfactory system has direct access to the limbic system which is the part of the brain responsible for them. When essential oil molecules are breathed into the nasal passages, receptors in the olfactory mucous membrane identify an odor. The sensory stimulation is transmitted through the olfactory bulb along the olfactory nerve, crossing the blood brain barrier, to engage the limbic system in the temporal lobe of the forebrain. Nerve impulses triggered in the limbic system affect other areas of the brain that are responsible for secreting hormones and regulating body functions. In addition respiration carries essential oil molecules to the lungs where they pass into the circulatory system. The entire process from initial inhalation to corresponding body responses takes place in a matter of seconds. A simple inhalation can cause instant changes in the body.
Application methods for inhalation include steam from a bowl or shower, diffusers, nebulizers, jewelry, personal inhalers and sprays. When using a room air diffuser 1 drop of essential oil to each 20 ml of water is a good ratio. It is also important to consider who will be in the room at the time the diffuser is running and choose essential oils accordingly. Small children including infants, frail or immune compromised individuals and pets require special considerations because there are essential oils that are contraindicated for certain populations. Cats should not be in a closed room with a diffuser going because they lack a specific liver enzyme that is necessary to metabolize essential oils.
Diffusers should not be used for hours at a time unless the concentration of essential oil in the water reservoir is so low that it is almost undetectable. An intermittent schedule of 30 to 60 minutes on and 30 to 60 minutes off will prevent over saturation of the olfactory system. Habituation to an aroma occurs after about 60 minutes anyway so diffusing longer than that is not helpful. Care should be taken to place a diffuser where the mist will not be directly breathed in but allows it to work in ambient air.
Diffuser jewelry, personal inhalers and sprays may be used as needed for a more targeted or personal application where using a diffuser would not be appropriate. Using a diffuser in public places, work spaces, doctors’ offices and classrooms is not recommended. Certain scents are thought to be triggers for asthma, respiratory conditions, headaches and allergic reactions in some people.
Have you seen aromatherapy jewelry? Felt discs in pretty lockets, clay pendants, lava bead bracelets and necklaces are in right now. They are a popular way to use the benefits of essential oils in a way that is similar to using a personal inhaler. Aromatherapy utilizes scent to deliver the therapeutic properties of aromatic essential oils instantly. Inhalation is one of the most effective ways to use essential oils to manage stress, increase focus, relieve anxiety, aid sleep, boost mood and influence emotions. Many times using a whole room diffuser is not a practical or convenient method and aromatherapy jewelry can offer a targeted form of administration that is easy to access. I have come up with a neat way to use local sheep’s wool to make an interesting and practical diffuser pendant. My friend Heather taught me to make colorful felted wool balls from wool that she produced and bartered for as well. I place them in spiral wire cages and use hand sewn silk cording to hang them from. They can be worn as a necklace or used as an indirect diffuser in the car or at work where a whole room diffuser might not be welcome. My Stay Focused blend of essential oils helps to keep me alert on my long commutes though any blend or single essential oil could be used as needed. If you have questions about how to use essential oils in diffuser jewelry or any aromatherapy questions in general, shoot me an email. Happy Spring!
One of my favorite ways to use essential oils is with a personal inhaler. There are inexpensive plastic ones, aluminum with glass inserts and the easy DIY method with a cotton ball in a bottle. Personal inhalers are an effective way to carry your essential oils in a safe and portable way. They also contain the aroma of the oils to be used individually, anytime that you need them, without affecting others in the room. Sometimes running a diffuser isn’t practical or advised, such as when small children or pets are present or in a public or communal space. A personal inhaler is a great alternative to room air diffusion. They are also an economical way to use essential oils because the approximate 15 drops of essential oils in a personal inhaler can last for about three months.
An inhaler is good to use when your goal is to support emotional well-being, relieve stress, encourage restful sleep, boost concentration and focus, as well as to promote respiratory health. When using essential oils to address an issue that is not related to the skin, joints or muscles, inhalation is the most effective mode of application. Inhalation of essential oils into the nasal cavity allows the aromatic molecules to directly affect the limbic system, they are also absorbed into the bloodstream via the lungs.
When I make a personal inhaler I like to use just a few oils in order to keep from muddling the scents. I choose oils that I think will work together for a desired result. When making an inhaler for children I will use fewer total drops of essential oils (usually about 10 total drops) on the cotton wick. A personal inhaler is easy to use, just remove the cover and hold the end with holes in it to one nostril, press the other nostril closed and inhale through your nose. Repeat this on the other side. You may use a personal inhaler as needed throughout the day.
Hi Everyone, Here are a few articles that I think might be helpful to highlight some of the concepts that we discussed in class last week. As always, please feel free to contact me if you have any questions that I can help you with. I hope you are all getting good results from the inhalers and blends that you created. I would love to hear how they are working for you.
