Frankincense tends to be the most expensive bottle on the shelf, and it is fair to ask whether it is worth it. The answer depends on what you expect from it — but it is worth knowing that this is where the risk of adulteration is highest.
What it actually is
Frankincense is not a single plant. Several species of the Boswellia genus are harvested, and they differ in aroma, price and composition:
| Species | From | Character |
|---|---|---|
| Boswellia carterii | Somalia | The most widespread; balanced, faintly citrus |
| Boswellia sacra | Oman | The most expensive; deeper, more balsamic |
| Boswellia serrata | India | Cheaper; drier, more turpentine-like |
| Boswellia frereana | Somalia | Fresher, more pine-like, rarer |
The oil is distilled from the hardened resin that seeps out when the bark is scored. Collecting resin is manual work, the trees grow slowly, and over-tapping damages them — which is part of why the price is high, and why sustainable sourcing is worth paying attention to.
What it smells like
Warm, resinous, a little smoky, with a faint citrus lift on top. Not floral and not sweet — rather, serious. This is the aroma most people know from church, because burning frankincense resin is a practice thousands of years old.
How I use it
In the diffuser, for evening reading. Two or three drops. It stands on its own, but orange makes it warmer and lavender makes it softer.
In a face oil. This is its most popular use: 1% in a good carrier oil (almond, jojoba, apricot kernel). In the evening, after cleansing, a few drops.
For meditation or breathing practice. One drop in the palms, rubbed together, a few deep breaths. It is the simplest ritual I know.
Safety
| Consideration | Frankincense (Boswellia spp.) |
|---|---|
| Dilution on adult skin | 1–3% |
| Phototoxicity | None |
| Children | Over 3 years, heavily diluted |
| Pregnancy | Ask your doctor |
| Storage | Keep cool; it can become more irritating once oxidised |
Adulteration — what to watch most closely
Frankincense is one of the most frequently diluted essential oils. The typical method is to extend it with a cheap carrier oil or another oil of similar aroma, sometimes with synthetic components added.
What to look for:
- Botanical name and species. If the label only says “frankincense” with no species, that alone is a warning sign.
- Price. If a 15 ml bottle of frankincense costs the same as lavender, it is not frankincense.
- A greasy mark. Put one drop on white paper. Essential oil evaporates without trace within a few hours. If it leaves a greasy mark, it has been cut with carrier oil.
- GC/MS analysis. This is the decisive evidence. Serious suppliers publish it per batch.
Common questions
Why is it so expensive? Hand-collected resin, slow-growing trees, low yield. The price reflects real cost — if it is cheap, something is wrong.
Are the resin and the oil the same thing? No. Resin is burned (it smokes); oil is distilled. The two aromas are related but not identical.
Which species should I buy? If you are starting out, Boswellia carterii offers the best value. Sacra is finer but considerably more expensive.
