Frankincense Essential Oil Types Compared: Which Is Best?
Frankincense essential oil is not one single product. Bottles sold under that name come from different Boswellia species, countries and distillations, and they can smell and read very differently on a lab report. This guide compares the main types, explains what to check on a label and answers the question most people really ask: which one is best?
What is frankincense essential oil?
Frankincense essential oil is made by steam distillation or hydrodistillation of the oleo-gum resin of Boswellia trees [1]. The resin is the hardened sap that the tree releases when its bark is cut. There are around twenty Boswellia species across Africa, Arabia and South Asia, and only a few are traded in significant amounts: B. sacra, B. carteri, B. frereana, B. papyrifera and B. serrata [1].
The oil and the resin are not the same thing. A review of Boswellia sacra reports that the resin holds roughly 5% to 7% essential oil, alongside gums and other compounds [2]. The resin is what people burn as incense. The oil is the volatile part that distillation carries over.
A CO2 extract is a third product. It uses pressurized carbon dioxide instead of steam, captures a wider range of compounds and is still quite rare [3]. This matters because boswellic acids, the compounds behind many claims you read about frankincense, are found in resin extracts and CO2 extracts. Robert Tisserand found no reliable report of boswellic acids in any frankincense oil made with normal distillation [4]. So research on resin extracts or supplements does not carry over to steam distilled essential oil.
The main frankincense species compared
The table below sets out what the sources report. Treat the percentages as examples, not specifications. The same species can give very different numbers from one batch to the next.
Species | Typical origin | Scent as described | Main components reported | Price level |
Boswellia sacra | Oman and Yemen [2] | Prized for its aroma [3]. One retailer guide: rich, warm, sweet-spicy [6] | Alpha-pinene about 81% on average in Mughsayl (Oman) samples and about 60% in Hasik samples. Limonene 3.7% vs 13.6%. Myrcene 1.1% vs 11.4% [2] | Often described as premium. Hasik oil is reported as higher priced than Mughsayl [2] |
Boswellia carterii | Somalia and Somaliland [1][3] | One retailer guide: fresh, citrusy, slightly camphoraceous [6] | Lab-distilled reference oils: alpha-pinene 31.8% to 33.3%, limonene 10.1% [5]. One analyst sees 30% to 60% alpha-pinene in carterii oils [7] | Widely sold [3][6]. No reliable price comparison found |
Boswellia serrata | India [3] | One retailer guide: warm, spicy, balsamic [6]. One analyst rates its odor quality lower [7] | Alpha-thujene is typically the lead compound: 22.7% to 47.4% in one study, 29.3% and 61.4% in others [2] | Often less costly than the other types [3][7] |
Boswellia frereana | Northern Somalia [1] | Distinct. One retailer guide: fresh, lemony-pine [6]. One analyst rates its odor quality below carterii [7] | Alpha-pinene, alpha-thujene and p-cymene [1]. One analyst saw alpha-pinene from 2% to 67% and p-cymene 5% to 20% [7] | No reliable price found. Oil yield is low, about 2% [7] |
Boswellia papyrifera | Ethiopia and Sudan [1] | One retailer guide: resinous, slightly sweet [6] | Octyl acetate leads: 57.1% to 65.7% in the studies a review lists [2], up to about 70% reported by another analyst [7] | No reliable price found. Not well documented as a consumer oil [5] |
Is Boswellia carterii the same as Boswellia sacra?
It depends on who you ask. Oshadhi notes that carterii is considered synonymous with sacra, and that the distinction lies in origin: carterii from the Horn of Africa, sacra from the Arabian Peninsula [3]. A buyer's guide from Zea reports that Kew's Plants of the World Online lists carterii as a synonym of sacra, while much of the chemistry literature treats them as two species [5]. Tisserand writes that most authorities consider them synonymous, though some claim they are distinct [4].
In practice you will see both names on labels. The name alone does not tell you which oil is better.
Why the Latin name alone does not settle it
Climate, location and harvest time all change what ends up in the bottle [1][2]. Published figures for alpha-pinene in frankincense oils on sale worldwide range from 5% to 75% [2]. The age of the resin before distillation also matters, which is one reason a standard lab test can struggle to tell sacra from carterii [2].
Some analysts now argue for describing frankincense by chemotype, meaning its dominant chemistry, as well as by species. One chemist has seen the same claimed species produce drastically different chemistry, and two claimed species produce nearly the same [7]. So a label such as "Boswellia carterii, alpha-pinene type" tells you more than "frankincense".
How to choose a good frankincense essential oil
Quality does not guarantee safety, but it tells you what you are buying. Check these points before you buy:
The full Latin name. "Frankincense" alone could mean several species.
Country of origin. Where the resin was grown and, if stated, harvested.
How it was extracted. Steam distilled oil and CO2 extract are different products [3][4].
A batch GC-MS report or certificate. A report is the way to see what is in a specific batch. A label cannot show it.
Dark glass. Amber bottles keep light out.
Honest wording. Vague terms such as "therapeutic grade" do not tell you what is in the bottle. Be cautious of any seller who says an oil treats or cures a condition.
The adulteration risk
A 2022 study bought 21 commercial oils sold online as pure Boswellia carteri and analyzed them. Every one showed some form of adulteration or contamination. Examples included synthetic limonene, synthetic octyl acetate, castor oil and the addition of other Boswellia species or of resin [1].
Keep this in proportion. It is a single laboratory study of 21 oils bought in one place, and it says nothing about any particular brand. It does show why species labelling and batch testing matter in this category.
Using frankincense essential oil safely
Safety rules for frankincense essential oil are the same as for other essential oils. The Tisserand Institute's guidance is clear: do not apply undiluted essential oils to your skin [9]. Its dilution article also links to reports of skin reactions after undiluted frankincense in a blend [8].
Use | Typical dilution |
Reaction-prone or impaired skin | 0.2% to 1% |
Face and sensitive areas | 0.5% to 1.2% |
Body oils and lotions | 1% to 3% |
These are general guidelines from Tisserand [8]. Start low, and increase only if needed. Our guide to essential oils and itchy skin explains dilution and patch testing step by step.
Safety checklist:
Dilute in a carrier oil before it touches your skin
Patch test a new oil and wait at least 24 hours
Keep it away from eyes, and out of reach of children [9]
Do not swallow essential oils unless a qualified practitioner has told you to [9]
When diffusing, run the diffuser 30 to 60 minutes on, then 30 to 60 minutes off, with some fresh air [9]
Keep oils away from naked flames [9]
Keep oils and diffusers away from pets. Cats in particular are sensitive to many plant compounds [5]
Ask a doctor first if you are pregnant, have a skin condition, epilepsy or asthma, or take prescribed medication [9]
So which frankincense essential oil is best?
There is no single best frankincense essential oil. The best one depends on what you want, and the sources support these pointers:
A rich, resinous, premium oil: look at Boswellia sacra. Oshadhi calls it particularly prized for its aroma [3]. Expect to pay more, and note that sacra from different Omani areas differs in chemistry and price [2].
A familiar all-rounder: Boswellia carterii is probably the best known and most researched type [3].
A budget-friendly, spicier oil: Boswellia serrata is often less costly, which makes it an easy starting point [3]. One analyst rates its odor quality lower than the other types [7].
Something different: Boswellia frereana has its own aroma profile. Boswellia papyrifera has very different chemistry, led by octyl acetate. Both are less documented as consumer oils [5].
Whichever you pick, buy on the label, not the story. You want the full Latin name, the country of origin, the extraction method and a batch report. Price and scent preference come after that.
Frankincense essential oil at PALINOVA
PALINOVA sells Frankincense Essential Oil (Boswellia sacra) in a 5 ml amber glass bottle for 17.00 EUR. The product page lists steam distillation as the method of extraction, and our products are tested before they are released.
Like any frankincense essential oil, it is concentrated. Dilute it before it touches your skin and follow the safety steps above.
The bottom line
Frankincense essential oil comes in several types, and the Latin name is only part of the story. Compare scent, origin, extraction method and test results rather than looking for one winner. Use it with care: dilute, patch test and speak to a healthcare professional if you have any concerns.
