All About Eucalyptus Oil: Why We Use Two Species in the Breathe Collection
All About Eucalyptus Oil
One word, two very different essential oils — and the story behind your Proper Xchange Breathe collection.
The Short Version
- Eucalyptus Essential Oil is a purifying, cleansing, clarifying, and immune-boosting oil — ideal for aromatherapy, skin, and surface care.
- There are around 700 eucalyptus species worldwide; approximately 500 produce an essential oil. Global production is led by Eucalyptus globulus (Blue Gum).
- Each species has a different chemical composition and aromatic character — which is exactly why we chose two for our Breathe collection.
- Eucalyptus oils support respiratory health, muscle comfort, and cleansing — in balms, inhalers, sprays, and massage blends.
- The key active compound is 1,8-cineole (eucalyptol) — present in varying concentrations across species.
Why We Use Two Eucalyptus Species
When most people say "eucalyptus," they picture that crisp, clean spa-steam inhale. But eucalyptus isn't one oil — it's a whole family. The species shapes the experience. At Proper Xchange, we match the species to the ritual.
Eucalyptus Radiata
Eucalyptus radiata · 1,8-Cineole 65–75%Rounded, fresh, and slightly sweet — radiata is our everyday eucalyptus. We chose it for the formats that stay close to your skin or linger in your space.
- Breath Roll-On
- Breathe Body Oil
- Breathe Room, Linen & Body Spray
Eucalyptus Globulus
Eucalyptus globulus · 1,8-Cineole >80%Bold, pungent, and unmistakably "spa" — globulus is the classic eucalyptus statement. We chose it for our shower steamers, where steam heat activates the aroma at its most powerful.

The Science Behind the Choice
Both Eucalyptus radiata and Eucalyptus globulus are high in 1,8-cineole (eucalyptol) — the compound most responsible for that clear, refreshing eucalyptus sensation. But there's a meaningful difference in concentration and aromatic character:
Radiata
Eucalyptus radiataKnown to be one of the gentler eucalyptus oils, with a fresh, camphoraceous, more rounded aroma. The slightly lower cineole content gives it a subtler, sweeter character — ideal for everyday skin-contact formats.
- Fresh, crisp, slightly sweet & woody
- Also contains: Limonene 7–12%, α-Pinene 3–7%
- Origin: Australia / South Africa
- Steam distilled from leaves & twigs
Globulus 80/85
Eucalyptus globulusThe dominant global eucalyptus species — "Blue Gum." The 80/85% designation means the cineole has been concentrated via rectification, producing a stronger, more pungent experience perfect for shower steam.
- Strong, pungent; herbaceous with woody notes
- Cineole elevated by rectification
- Origin: China
- Steam distilled from leaves & twigs
A note from Tisserand Institute: Radiata is sometimes described as "gentler" than globulus — it does have slightly lower 1,8-cineole and a softer aroma — but "the difference in terms of safety is almost negligible." Both are wonderful for respiratory support. The difference is primarily about aromatic character and experience design.
Where Eucalyptus Comes From
The eucalyptus tree is commonly associated with Australia — and koalas, whose entire diet is eucalyptus leaves. Most of the ~700 varieties grow as tall trees; a few grow as shrubs. The tree goes by nicknames like Fever Tree, Blue Gum Tree, and Stringy Bark Tree, depending on its part of the world.
The Aboriginal people of Australia were the first to harness eucalyptus, calling it kino. They made leaf infusions to treat body pain, colds, sinus congestion, and fevers — hence the "Fever Tree" nickname. Early English settlers observed this folk medicine; stories spread, pharmacists began planning commercial production, and leaves of Eucalyptus radiata were among the first to be distilled.
Though Australia remains the origin and primary source, eucalyptus cultivation spread to Brazil, Europe, Greece, China, and India. By the 1880s, surgeons were using eucalyptus oil in operations for its antiseptic properties. Today, global production is dominated by Eucalyptus globulus (Blue Gum).
Of the ~700 species worldwide, approximately 500 produce an essential oil. The species, genetic factors, and growing conditions all determine the quality and aromatic character of the final oil.
What Makes Eucalyptus Oil Work
Eucalyptus oil's active chemical components contribute to its reputation as a purifying, cleansing, clarifying, and immune-boosting oil. Its healing benefits can be attributed to anti-inflammatory, antispasmodic, decongestant, antiseptic, antibacterial, and stimulating qualities. Here are the main active constituents:

Used in aromatherapy, the cooling scent of eucalyptus oil is known to relieve mental exhaustion by boosting circulation to the brain, stimulating the mind out of sluggishness, and rejuvenating the spirit. Those experiencing sinus congestion can diffuse eucalyptus throughout the night to clear nasal passages and eliminate harmful airborne bacteria.
How Eucalyptus Oil is Extracted
Eucalyptus Essential Oil is steam distilled from fresh or partially dried eucalyptus leaves. The geographical conditions under which the tree grows — environment, season, climate, water availability, soil nutrients, UV radiation, and stage of plant development — all affect the yield and chemical composition of the resulting oil.
The oils are typically clear and carry the characteristic aroma of their botanical species. While environmental factors do play a role, genetic factors (the species itself) are the most influential determinant of oil quality and chemical profile — which is exactly why species selection matters so much in formulation.
One notable exception: Eucalyptus polybractea (Blue Mallee) is the only major eucalyptus species that can be mechanically harvested — the plant is cut close to the ground and fed directly into a mobile still, making it one of the most efficiently produced eucalyptus oils.
How to Use Eucalyptus Oil
The uses for eucalyptus essential oil are abundant — from aromatherapy and body care to household cleaning. Here are the primary application categories:
Aromatherapy & Diffusion
Add 3–5 drops to a diffuser for a revitalizing, air-purifying atmosphere. Especially effective during seasonal changes.
Shower Ritual
Place a shower steamer on the floor away from direct water flow. Inhale the steam for a spa-quality respiratory experience.
Topical (Diluted)
Blended with a carrier oil, eucalyptus provides cooling, soothing relief for muscles and joints. Always diluted.
Room & Linen Spray
Mist onto linens and in the air for a naturally fresh, antimicrobial scent without synthetic fragrance.
Natural Cleaning
Combine with lemon and tea tree, dilute with water, and use as a natural surface cleaner or fabric freshener.
Skincare & Hair
Diluted eucalyptus moisturizes an itchy scalp and supports a healthier complexion when properly blended in a carrier.

-
02
The Mid-Day "Stay Clear" Moment
Mist your space or linens lightly with Breathe Room, Linen & Body Spray. The Eucalyptus radiata base keeps it fresh and clean without being overpowering — a quick reset between tasks or during afternoon sluggishness.
-
03
The On-the-Go Breathe Moment
Roll the Breath Roll-On onto your wrists or pulse points and cup your hands over your nose for a few focused breaths. Radiata's clear, rounded eucalyptus — anywhere, any time.
Using Eucalyptus Oil Responsibly
Eucalyptus essential oils are powerful and should be used thoughtfully. Here is a summary of key safety considerations:
- Do not ingest eucalyptus essential oil. As per NAHA guidelines, ingestion is not recommended.
- Always dilute before topical application. Using undiluted oil can cause skin irritation.
- Patch test first — perform a skin test prior to use, especially with sensitive skin.
- Avoid eyes, inner ears, and other sensitive mucous membrane areas.
- Never apply to the face of a child under 2 years old.
- Pregnant or nursing? Consult a healthcare professional before use.
- Individuals with high blood pressure or epilepsy should consult a doctor before using high-cineole eucalyptus oils.
- Keep out of reach of children and pets.
