Passive & Active Diffusing: Part Two

Last month, I wrote about Passive Diffusion using, for example, Wood or Aromatherapy Jewelry. You can read about this by going to and keyword searching “Passive Diffusing’. This month, I finish out my discussion on diffusing by discussing the ins and outs of Active Diffusion.

Active Diffusion: Most folks know this aroma-tool as a diffuser — the old- school diffuser method is a candle beneath a glass, metal or ceramic vessel that holds water and your essential oils. As the candle warms the water, the essential oils and their aromas are released. While this works in a pinch, do know that heat quickly causes the volatile molecules in an essential oil to evaporate – this means the aroma will not last very long. Also, heat changes the aroma and chemical structure of essential oils.

A popular method of active diffusing is using a nebulizer. A nebulizer uses a particular technology that vibrates water and essential oils at a very high frequency, thus blending water and oil and sending this mix out into the room as a cool mist. There are some very specific safety issues and efficacy issues to consider when using this method of active diffusing.

One, it is easy to overwhelm your sense of smell. Follow the manufacturer’s instructions for how many drops to add to your particular model. Each model will have a different water capacity and therefore requires more or less drops of essential oil.

Two, when shopping for a nebulizer, choose one with a timer. As we discussed last month, as soon as you breathe in essential oils, the aromatic molecules enter your bloodstream. Diffusing non-stop may overwhelm your olfactory system and those sharing your breathing space. As soon as these aromatic molecules enter your bloodstream, they start to do their ‘work’ (for example, on your mood), and will do so for approximately 20-90 minutes. It is therefore unnecessary and an overuse of aromatic essential oils to diffuse non-stop. Save money, your essential oils and longevity of your nebulizer while using aromatherapy safely! The more timer options the better. Most I have seen have a 1-hour timer. You can also set a reminder on your phone – as little as 5 minutes of diffusing at a time has been shown to be effective. Keep in mind what your intended purpose for diffusing is. For example, during cold and flu season you may want to increase the frequency you diffuse. I routinely run my nebulizer at 1-hour intervals throughout my day, changing up the blend as my day progresses.

Three, be aware of who else shares your breathing space. Babies, children, pets and anyone not easily mobile will be exposed to and affected by the aromas diffused into the air. Pets need an escape route, so make sure they have one. And you will be responsible for monitoring everyone who is in the room and their response to the aroma.

Other active diffusion choices: The Hubmar Aroma-Pearl uses cold-fusion technology to disperse the aroma into the air; the Wall-Ball is a plug-in device that gently warms a ceramic plate and cotton pad to diffuse; the Car-Scenter uses a similar technology but works with the lighter outlet in your car. I carry these three models by Hubmar, a Canadian company, at the market.

Passive & Active Diffusing: Part One

Maybe you’re asking yourself, ‘How hard can it be to diffuse essential oils? Don’t you just, you know, diffuse them?’

Click to Read Part Two: Active Diffusing

The answers to the above questions are, you guessed it – Yes, and no! Yes it’s ‘simple’; and no, you don’t just ‘diffuse’ them! There are some very specific safety issues and efficacy issues to consider when diffusing. In terms of efficacy, let’s start with passive diffusion.

Stainless Steel Aromatherapy Pendant

Passive Diffusion: This refers to the application of a drop or two of essential oil(s) to an absorptive aroma-tool that over time gently releases your aromatherapy. The simplest passive diffusion aroma-tools are, for example, a tissue or a cotton ball. In terms of efficacy, research has shown that simply ‘sniffing’ your chosen essential oil or blend allows the aromatic molecules to enter your blood stream immediately via your lungs and travel around your body via your circulatory system. This ‘sniff’ method also allows the aromatic molecules to go straight to work via the olfactory system – where the aromatic molecules can have a very immediate effect on your mood and emotions via the limbic system.

Inhaler Stick for passive diffusion

In terms of duration, the aroma will last depending on the essential oil or oils used and the number of drops applied. I recommend ‘sniffing’ your aroma-tool before adding a fresh drop. The essential oil(s) or blend will change its aromatic composition over time as the top note essential oils diffuse off or evaporate first, with the base notes hanging on aromatically, so to speak. Most citruses like Lemon, Lime and Sweet Orange are top notes and will be the first to evaporate. Whereas the aroma of Cedarwood Atlas, Patchouli and Vetiver, for example, will hang on much longer.

Terra Cotta Aromatherapy Pendant

In terms of safety, passive diffusion is relatively safe as long as you adhere to using only 1 – 2 drops (using more drops may overwhelm your sensitive olfactory and nervous systems). Some essential oils are contraindicated based on medical condition and age, for example. Please refer to a reputable reference (i.e. not something you read on the internet by a non-professional) or consult an accredited aromatherapist. And if you are trying to become pregnant, are pregnant and/or lactating, consult your healthcare provider before starting to use essential oils.

Heart-Felted Hearts

Passive Diffusion Choices:

• Inhaler stick
LJ Turtle Heart-Felted shapes
• Wood (raw & unfinished)
Aromatherapy Jewelry
Terra Cotta
• And the easiest – simply ‘sniff’ directly from the bottle or bottle’s cap.
