I get asked all the time about essential oils and the safety guidelines for each method of use.

This week I wanted to give you a quick overview of the main safety issues and how to use your oils so that you can use them safely and effectively in your own home.

Essential oils can be a wonderful addition to your health and wellbeing program. They are derived from natural substances such as trees, fruits, roots and flowers. However, just because they are derived from nature, it doesn’t mean that they are always safe to use. Natural doesn’t equate to safe. Water is safe, but in excess amounts, it can be dangerous. Arsenic is natural. Poison Ivy is natural. You get the gist.

There are some general safety guidelines which we need to adhere to, for the safety of our family, friends, animals and ourselves.

Method of Application

Essential oils may be applied to the skin, diffused, inhaled or taken internally. Each of these methods has safety issues which need to be considered. Inhalation is generally considered the safest, and ingestion that most risky. All methods are valid, however, each method needs to take into account the individual, the need, the quality of the oils, and the method of application.

Sometimes the simplest way to use oils is often the best. A drop or two on a tissue for inhaling can be great for nasal congestion. This approach can also be great for when feelings of anxiousness arise.

I will delve into different application methods and approaches in another podcast but for now, the overview of safety is as follows:

Dilution

The neat application of essential oils to the skin is best avoided as it can cause a number of potential concerns. Applying essential oils ‘neat’ means that you are placing the oils directly onto the skin without dilution or using them full strength. This practice was acceptable in the past; however, it is now known that this can cause irritations, sensitisations, and other skin issues.

In acute situations, it might be the best option to use a known ‘safe’ oil neat, however, this practice is becoming ill-advised. A drop of Lavender oil on a bee sting would be ok, however, if you were being exposed to bee stings continually, then this option may not be safe. You would need to come up with a safer and more effective option.

How do we dilute? We dilute our essential oils with fixed oils, or what we call in aromatherapy terms carrier oils. Carrier oils would be oils like Fractionated coconut oil, MCT oil, Sweet Almond oil, Avocado, Macadamia and Jojoba to name but a few.

In aromatherapy, a 2.5% dilution is a good and safe level for many applications. To work out how many drops of essential oils you need to add to your preferred carrier, first you need to know your amount of carrier.  Say you have 10mls of carrier, half that number, which in this case is 5), then and add that number of essential oils in drops for a 2.5% dilution.  10mls equals a total of 5 drops for a 2.5% dilution. 20mls would be 10 drops in total. 5mls would be 2.5drops which you can’t do so go with the 2 drops. Please note that is equation is based on the assumption that 20 drops equal 1ml.

You will find other charts available on how to dilute, but first check the basic assumption of how many drops per ml. We have referenced the Tisserand chart for you, note that this chart assumes 30 drops per ml.

You can also go to Twenty8 for the Quick Reference Blending Guide to download to help make it even more simple right here.

In general, you will find most aromatherapy essential oil blends will be diluted at a 1% to 5% dilution. At these rates, they generally won’t pose a safety risk. When we increase the dilution, that is more essential oils less carrier oil, the risk is increased. The following advice is based on Tisserand’s safety guidelines.

• For facial applications, a 0.2 to 1.5% dilution is considered safe.

Storage and Shelf Life

Keep your oils in a safe place – ensure that all bottles are tightly closed, stored in a cool area, and away from direct sunlight. Light and oxygen are not your oils best friends. In fact, they can degrade your oils more quickly. If your oils degrade, also known as oxidisation, it can make them irritating and less effective.

Essential oils do have a shelf life. Citrus oils, such as Lemon, Lime and Orange are more susceptible to degradation than root oils such as Vetiver and Patchouli.

Phototoxicity

Some essential oils are phototoxic meaning that they can cause irritation, inflammation, and redness when exposed to sunlight. In general, Citrus oils are the most likely to cause a phototoxic reaction due to their chemical makeup, however not all oils are photosensitive or phototoxic. The most common oils that are photosensitive are:

• Bergamot (Citrus bergamia)

There are, however, non-photosensitive versions available, and it is, therefore, prudent to look for and use these, from a safety perspective.

General safety Notes

• Do not place essential oils directly in the eyes, ears, nose and genitals.

If you have any doubts, questions or concerns, please consult with your primary healthcare practitioner, or a qualified professional aromatherapist. To find a professional aromatherapist in your area, check www.iaama.org.au or www.australiannaturaltherapistsassociation.com.au
