Understanding the three types of frankincense essential oil and how to choose the right one
You're standing in a shop, looking at three different bottles of frankincense essential oil. All three say "100% pure." All three look identical. But the prices are wildly different—one costs nearly triple the others.
What's the difference? And more importantly, which one do you actually need?
For thousands of years, frankincense has been one of the most prized substances on Earth. Known in Arabic as Luban (اللبان), this aromatic resin was valued as highly as gold by ancient Egyptians, Romans, and Babylonians. It traveled the legendary Incense Trade Route from Arabia to the Mediterranean. It was one of three gifts presented to the infant Jesus.
Today, frankincense essential oil remains a staple in aromatherapy, natural perfumery, and holistic medicine. But here's what most people don't know: not all frankincense is created equal.
The resin comes from several species of Boswellia trees, each with a unique chemical profile, aroma, and therapeutic strength. The three you'll encounter most often are Boswellia sacra, Boswellia carterii, and Boswellia frereana.
This guide will help you understand the real differences—and choose the right one for your specific needs.
How Frankincense Is Made: The Shared Origin
Before we dive into differences, let's understand what these species have in common.
All three belong to the Burseraceae family. When the bark is "tapped" (scored with a blade), the tree exudes a milky resin that hardens into translucent "tears" when exposed to air. These hardened tears are then steam distilled to produce essential oil.
But geography and genetics create distinct personalities.
- Boswellia sacra → Native to Oman and Yemen
- Boswellia carterii → Traditionally from Somalia and Ethiopia
- Boswellia frereana → Thrives in the highlands of Somaliland and Oman
Think of them as siblings from different regions—related, but each with their own character.
Boswellia Sacra: The Sacred One
Where it grows: Dhofar region of Oman and parts of Yemen
Reputation: Often considered the highest quality frankincense in the world
Price point: Most expensive of the three
The Chemistry
B. sacra is rich in monoterpenes, particularly:
- α-pinene (up to 68% of the oil) - That bright, pine-like opening note
- Limonene - Citrus freshness
- β-phellandrene - Subtle complexity
- Incensole acetate - The compound that makes this oil special for mood
The Aroma
Bright, complex, and lemony at first breath, then deepening into woody, balsamic richness. It's often described as the most "spiritual" of the frankincense varieties—and when you smell it, you understand why.
What It's Best For
Meditation and spiritual practice
B. sacra is renowned for deepening meditation, slowing breathing, and creating mental space. That incensole acetate compound? Research suggests it may activate ion channels in the brain that produce anti-anxiety effects. This is why it's been burned in temples for millennia—it genuinely affects consciousness.
Anxiety and stress
The chemistry that makes it spiritual also makes it calming. Clinical aromatherapists reach for this when clients need nervous system support.
Anti-aging skincare
Used to rejuvenate aging skin and reduce the appearance of scars. The resin's preservative qualities translate beautifully to skin preservation.
Who should buy it: People who meditate regularly, use aromatherapy for anxiety, or want the "best of the best" for skincare. If you're creating a sacred space ritual, this is your oil.
Boswellia Carterii: The Somali Healer
Where it grows: Somalia and Ethiopia
Reputation: The most common species in the global market; therapeutically powerful
Price point: Mid-range; excellent value
The Chemistry
Chemically very similar to B. sacra:
- α-pinene and limonene dominate
- Isoincensole acetate - Key diterpene biomarker (same as sacra)
- Octyl acetate - May be slightly higher depending on harvest region
The confusion: Scientific literature sometimes treats B. carterii and B. sacra as synonymous or very closely related subspecies. For practical purposes, they're therapeutic cousins.
The Aroma
Warm, sweet, woody, and balsamic with subtle spicy notes. Generally softer and less "bright" than Omani sacra—think rounded warmth rather than sharp clarity.
What It's Best For
Respiratory support
This is THE frankincense for colds, coughs, bronchitis, and asthma. Acts as an expectorant and antiseptic for the respiratory tract. In clinical aromatherapy, this is the default choice for lung support.
Immune boosting
French aromatherapy schools rate it highly (++++) as an immune stimulant and energizer. Use during cold and flu season.
Wound healing
Excellent cicatrizing (wound-healing) properties. Use diluted for cuts, scars, and skin infections.
Anti-inflammatory
All frankincense contains boswellic acids that inhibit inflammatory enzymes, but carterii is particularly well-studied for this.
Who should buy it: Anyone dealing with respiratory issues, frequent illness, or who wants a versatile therapeutic oil at a reasonable price. This is the "workhorse" frankincense.
Boswellia Frereana: The King of Frankincense
Where it grows: High elevations in the Caledonia Mountains of Somaliland
Reputation: Called "Maydi" locally; often chewed as gum rather than burned
Price point: Can be harder to find; mid-to-high range
The Chemistry
This is where it gets really interesting. B. frereana is chemically distinct from the others:
- NO incensole family compounds (no incensole acetate)
- High levels of α-phellandrene dimers - Unique chemical fingerprint
- Completely different therapeutic profile as a result
The Aroma
Fresh, woody, spicy with hints of pine. Cleaner and sharper than the sweet, balsamic scent of carterii. Less "churchy," more forest-like.
What It's Best For
Pain relief
This is the analgesic frankincense. Highly regarded for relieving muscle and joint pain. If you have chronic pain, this is the one to try.
Arthritis and severe inflammation
Its unique chemistry makes it particularly potent for inflammatory conditions like rheumatism and arthritis. Use in topical blends.
Skin tightening and anti-aging
Prized for astringent properties. Many aromatherapists believe it's even more effective than other species for preventing wrinkles and toning mature, sagging skin.
Nervous tension and grounding
Helps relieve depression and nervous tension while keeping you grounded—not spacey like sacra can make some people feel.
Who should buy it: People with chronic pain, arthritis, or serious skin aging concerns. This is the "specialty" frankincense for targeted therapeutic use.

Can't decide? Many high-quality commercial blends combine these species to create well-rounded therapeutic effects. That's actually a smart approach.
How to Find Quality Frankincense
When shopping, always verify:
✓ Botanical name clearly stated - Boswellia sacra, Boswellia carterii, or Boswellia frereana
✓ "100% pure essential oil" - NOT "fragrance oil" or diluted
✓ Country of origin listed - Omani oils (sacra) command premium prices; Somalian (carterii) offers excellent value
✓ Dark glass bottle - Protects oil from light degradation
✓ Batch/lot number - Shows proper sourcing and testing
Red flags:
- No botanical name, just "frankincense"
- Suspiciously cheap (quality frankincense isn't cheap)
- Clear glass bottles
- "Aromatherapy oil" or "fragrance oil" labels
The Bigger Picture
Frankincense is more than a scent. It's a liquid connection to ancient history, a tool for modern wellness, and a reminder that some of nature's most powerful medicines come from the harshest, most unforgiving landscapes on Earth.
Whether you choose the sacred sacra for meditation, the healing carterii for immunity, or the kingly frereana for pain relief, you're bringing a piece of the Arabian and African earth into your daily ritual.
And now you know exactly which piece you're getting.
