Citrus Oils & Aromatherapy

Citrus Essential Oils – The Facts & Fun, Historical Behind the Scenes of some of our favourite aromatic molecules. 

Citrus essential oils are curiously found in the peels or rinds of the fruit, not the fruit itself. It’s for this reason that peeling an orange, for example, gives off such a delicious scent. If you take a healthy orange peel and squeeze it, you’ll be able to see a tiny spray of the essential oil.

To extract these essential oils the rinds are cold-pressed, instead of steam-distilled like most other essential oils. An exception to this is the beautiful Neroli (Citrus aurantium) oil which is steam-distilled from the flowers of the orange tree.

Which citrus essential oil is right for me?

Some citrus oils appear very similar but are actually quite different. For example, Sweet Orange, Mandarin Orange, and Tangerine are all oranges but their essential oil properties and aromas vary.

Sweet Orange Essential Oil has the most typical orange aroma. It’s bright, energizing, uplifting, and when diluted and used on the skin it gives a beautifully healthy and glowing complexion. A great oil for women, men, and children – an all-around favorite. It’s been used in many natural cleaning products for its ability to cut through grease and leave a sweet and refreshing scent.

Sweet Orange Essential Oil is a great oil to diffuse in the home while entertaining as it’s well loved by most and gives a clean, uplifting, and energizing aroma to the home.

Blends well with other citrus essential oils as well as floral and minty oils.

 

Mandarin Essential Oil is similar in scent to Sweet Orange but with more of a complex aroma.

It has fruity, sweet, and green notes with a subtle floral scent. It’s the sweetest of all citrus oils and yet the most calming. This is a great choice for an evening oil to calm the mind from daily stressors.

 

Tangerine Essential Oil has a more delicate and peaceful aroma with the perfect touch of sweetness. Another calming oil that makes a great choice for children and those of all ages before bedtime or naps.

 

Caution – on Phototoxicity

A note of caution in regards to all citrus oils. Be mindful of the phototoxicity they cause during prolonged exposure to UV rays. Phototoxicity means your skin will be more sensitive to the sun, leaving you susceptible to sunburns and irritations from the sun. This may occur even if you simply absorbed the oil into your system. But, it is especially pronounced on areas of your skin that have the citrus oil applied AND are exposed to sun and heat.

Beyond the Latin Name!

Beyond just the proper identification, you are best to consult with a professional curator of essential oils. Why? Because even the latin name can be an approximation of the functional chemistry and useful components of the oil within the citrus.
