Blending essential oils can be a lot of fun, and like all artistic endeavours there are no real right or wrongs. But, knowing how to group and categorise individual oils can be really helpful, so that’s what we’ve done. Below, we have categorised oils by Effect, Scent, and Note.
When blending purely for diffusion you don’t need to worry about diluting the oils. But, for topical application or bath time blends, you will need to introduce a carrier oil to safely dilute your blends before coming into contact with the skin. Please refer to our Topical application guide below, for more information on safely diluting your concoctions.

Blending by effect
Below are the emotional, physical and spiritual effects each oil is known to impart or treat through the practice of aromatherapy.
Lavender, Geranium, Roman Chamomile, Marjoram, Sandalwood, Bergamot, Jasmine, Black Pepper, Tangerine, Orange, and Melissa.
Blending by aroma
The classification of essential oils by scent type or family.
Blending by note
Top notes are brightening scents composed of minuscule, delicate molecules that dissipate quickly. They’re used to create a fresh, uplifting aroma and are the ones you smell first when inhaling a blend.
Middle notes are the scents that follow once the top notes have dissipated, providing the blend with its body or “heart”. This is why the middle note is often referred to as the ‘heart note’. Lavender, for example, is considered a middle note.
Base notes represent a blends foundation, and refer to the most enduring essential oils, used to add depth and fullness.
Topical application
We would always advise purchasing organic, cold-pressed carrier oils from a reputable source. Carrier oils don’t usually cause allergic reactions, but when using on the skin it’s always prudent to perform a patch test, prior to application. If you’re allergic to tree nuts, you should not use oils derived from tree nuts. This includes Sweet Argan Oil, Almond Oil, and Apricot Kernel Oil.
When using a carrier oil to dilute your essential oils you should follow these important dilution guidelines:

Essential oils should never be used on a premature baby, but for children aged 3-24 months full body application should be subject to a general dilution of 0.25%-0.5%. This means applying 2-4 drops of essential oil for every ounce of carrier oil. when being used . For spot usage, you can use 9-27 drops of essential oil per 1 ounce carrier.
