Eucalyptus oil diffuser blends

Eucalyptus is definitely among my favorite essential oils. I love the fresh scent in all forms, from candles to bath bombs, and now these easy eucalyptus diffuser blends.

But eucalyptus offers more than just a refreshing scent. While the aromatic smell is definitely a perk, there are so many wellness and aromatherapy benefits that make eucalyptus worth your while.

Eucalyptus can aid with emotional stress and exhaustion. The oil also supports a healthy respiratory system, tackles sinus congestion, and releases a stuffy nose.

The potency of eucalyptus makes the essential oil also a great odor eliminator, air freshener, and bug repellent. Instead of unwanted odors, you’ll be left with a fresh and bright-smelling space. All good things, right?

Eucalyptus essential oil types

Botanists have discovered more than 700 hundred species of eucalyptus trees. It’s no surprise that different types of eucalyptus essential oils exit.

Eucalyptus essential oil comes from eucalyptus leaves and twigs going through a steam distillation process to release the precious oils from the plant materials.

Here’s a quick overview of the 5 most common eucalyptus essential oils:

Eucalyptus globulus

  • Facts: Eucalyptus globulus, aka blue gum eucalyptus, is the most common eucalyptus essential oil. It’s steam-distilled from the leaves of the Australian blue gum eucalyptus tree.
  • Composition: Cineole (aka eucalyptol) is the primary isolate of blue gum eucalyptus. The oil has antibacterial and antimicrobial properties.
  • Scent: E. globulus has a powerful, penetrating aroma with green, camphoraceous notes.
  • Shop: eucalyptus globulus

Eucalyptus radiata

  • Facts: Also called narrow leaf eucalyptus oil, the oil is steam-distilled from the leaves of the Eucalyptus radiata tree.
  • Composition: Limonene is the principal component of radiata, followed by α-terpineol.
  • Scent: The oil smells very refreshing with subtle citrus and peppery undertones. Radiata’s scent is slightly smoother and milder than eucalyptus globulus.
  • Shop: eucalyptus radiata

Eucalyptus dives

  • Facts: Eucalyptus dives is also known as peppermint eucalyptus. The oil is steam-distilled from the broad-leaved peppermint gum tree.
  • Composition: Eucalyptus dives contains mainly phellandrene and piperitone and has a lower cineole content than other eucalyptus varieties.
  • Scent: The oil has a strong, herbaceous smell with minty undertones that feels stimulating and uplifting.
  • Shop: eucalyptus dives

Lemon eucalyptus

  • Facts: Lemon eucalyptus essential oil is derived from the leaves of the Corymbia citriodora tree, the lemon-scented gum.
  • Composition: The oil consists mainly of citronella. The presence of PMD (p-menthane-3,8-diol) makes the oil an effective bug repellent.
  • Scent: Lemon eucalyptus features an enlivening, balsamic aroma with lemony or citronella-like overtones and smells less medicinal than the other eucalyptus oils.
  • Shop: lemon eucalyptus

Eucalyptus polyacetal

  • Facts: The oil is also known as blue mallee essential oil and is made from the leaves of the blue malle.
  • Composition: E. polyacetal features significantly high levels of cineol (up to 92%).
  • Scent: Blue mallee has a sweet, camphoraceous scent with a refreshing, cooling effect that benefits the respiratory system.

Which eucalyptus essential oil is best for diffusing?

All the different oils we just discussed exhibit similar aromatherapy benefits and are great eucalyptus diffuser blends. You can use them interchangeably or combine them for a synergetic effect.

Eucalyptus globulus is most widely available and diffuses very well. Dives is a wonderful option if you prefer a milder eucalyptus scent, while radiata provides a complex and nuanced eucalyptus scent.  


You may have heard that some eucalyptus essential oils are not safe for children under the age of 10. These oils include globulus, radiata, and polyacetal due to their high 1,8 cineole content.

However, these safety recommendations only concern the topical application of eucalyptus oil. They also warn against directly spraying these oils into the nose of children.

In their book “Essential oil Safety,” Robert Tisserand and Rodney Young state on page 526:

“1,8 cineole does not appear to be as toxic as is often believed, although elevated oral doses certainly are toxic and children are susceptible to cineole toxicity […].But this should not be taken to mean that any preparation containing 1,8 cineole is highly dangerous to children per se.”

It is perfectly safe to diffuse these eucalyptus diffuser blends around children. Still, in case you have any concerns, use eucalyptus dives and/or lemon eucalyptus.


If you have pets, stick to lemon eucalyptus essential oil since it’s the one pet-safe oil of the eucalyptus family.

Bug repellent

Also, if you diffuse intending to discourage insects, opt for lemon eucalyptus. Comparable to citronella, lemon eucalyptus contains scent molecules known as p-menthane-3,8-diol (PMD), a natural insect repellent.

Eucalyptus hydrosol

I also want to mention eucalyptus hydrosol (eucalyptus water) as an option for a eucalyptus diffuser. Hydrosols are a byproduct of the distillation process and contain trace amounts of essential oils.

Eucalyptus hydrosol is very mild and gentle, allowing you to reap the benefits of eucalyptus without the sometimes overpowering aroma.

Try eucalyptus hydrosol if you have ever experienced respiratory irritation or headaches using the essential oil.

To use it, simply fill the water tank in your diffuser with 1/2 hydrosol and 1/2 filtered water. You can also blend different hydrosols to create unique scents.

What essential oils diffuse well with eucalyptus?

The better question is: What essential oil doesn’t compliment eucalyptus? Eucalyptus blends well with different oils from the following scent groups:

  • Floral essential oils (like lavender or germanium)
  • Herbal scents (e.g., mint or rosemary)
  • Woodsy aromas (such as cedar or pine)
  • Spice oils (e.g., clove, cinnamon)
  • Green and camphorous scents (like vetiver or blue tansy)

How to use these eucalyptus recipes

  • Ultrasonic diffusers use sonic waves to create a fine mist containing microscopic droplets of water and essential oils. This type is my favorite option to diffuse. To use, fill the water tank, add your eucalyptus oil blend, and choose a diffusion setting.
  • Candle essential oil burners use the warmth of a burning tealight to diffuse the EOs into the air and provide a cozy light flicker. To use, pour water into the bowl, add your eucalyptus blend, and light the tealight below.
  • Room spray: To make eucalyptus room spray or a eucalyptus pillow mist, dilute your eucalyptus diffuser blend of choice in high-proof alcohol and transfer it into a fine mister spray bottle. Spritz a few pumps into the air for a quick refresh.
  • Diffusion crafts: Another idea is to use these eucalyptus oil diffuser blends to scent wax sachets, reed diffusers, potpourris, wax melts, or aroma beads.
