Frankincense (Boswellia): Origin & Use

Frankincense is the dried resin of trees of the genus Boswellia. Its characteristic marker compounds are the boswellic acids, a group of triterpenic acids to which high-quality extracts are standardised. No health claims are authorised for frankincense in the EU - which is why we describe it factually in terms of origin, ingredients, forms and quality. When buying, what counts is the botanical species, the boswellic acid content and laboratory testing.

Few natural substances have such a long history as frankincense: along the legendary Incense Route, the resin was once more precious than gold. Today it comes to us not only as an incense, but as a standardised extract in capsules. What lies behind it - and how you recognise good quality - is what we clarify here, soberly.

Origin and botany: a resin from barren regions

Boswellia trees grow in dry, often barren areas of North-East Africa, the Arabian Peninsula and India. To harvest it, the bark is scored; the milky sap that emerges dries in the air into the well-known resin granules, which are then collected by hand. Because aroma and composition depend heavily on species, location and climate, frankincense is a natural raw material with natural variations - not an industrially constant product. Particularly well known is Indian frankincense (Boswellia serrata), whose resin is frequently used for extracts.

The boswellic acids - characteristic marker compounds

Scientific interest in Boswellia focuses above all on the compounds contained in the resin:

Standardised extracts are often adjusted to a certain percentage of boswellic acids - this makes products comparable. How well such plant compounds are generally absorbed depends on the form and accompanying substances; background in Bioavailability simply explained.

Different Boswellia species - why the species designation matters

Several botanical species are traded under the collective term frankincense, differing in origin and composition. Besides Boswellia serrata, frequently used for extracts, there is Boswellia sacra, native to the Arabian Peninsula, as well as species such as Boswellia carterii or Boswellia papyrifera. The precise species designation is therefore an important feature for assessing a product: it allows conclusions about origin and typical marker-compound profile. Anyone comparing standardised extracts should, alongside the species, also pay attention to the stated boswellic acid content.

Why frankincense is receiving attention again today

The fact that a millennia-old incense resin is suddenly landing as a capsule in many people's medicine cabinets has to do with a general trend: the growing interest in plant-based natural substances and traditional systems of use such as Ayurveda. Frankincense combines two things that many people are looking for - a long, well-documented history of use and a clearly nameable, standardisable marker-compound profile (the boswellic acids). People interested in plant-based supplements around the topic of joints and mobility therefore often come across Boswellia. This describes the context of use - that is, why people engage with it - and is explicitly not a statement about any health effect.

Traditional use as a cultural-historical framing

Frankincense has one of the longest documented histories of use of all. As an incense it played a role in the religious and cultural rituals of many advanced civilisations, and in traditional systems of use such as Indian Ayurveda, Boswellia has long been known. Trade connected the growing regions of the Arabian Peninsula with the Mediterranean cultures via the so-called Incense Route. This mention serves solely as a cultural-historical framing and is explicitly not to be understood as a statement about any health effect.

Forms and use

Frankincense is available in several forms:

• Resin granules - the classic form, traditionally used as incense.
• Powder - ground resin.
• Extract/capsules - concentrated forms, usually with a standardised boswellic acid content.

As a dietary supplement, Boswellia is predominantly offered in capsule form with a standardised extract. For an overview of dosage forms, see Capsule, tablet, powder or drops?. Anyone exploring further plant-based substances around joints will find neutral framings in Glucosamine, chondroitin and MSM as well as in Devil's claw and MSM.

The decisive difference between the forms lies in the concentration: one gram of raw resin powder contains the boswellic acid content that nature gave it - with an extract, it is deliberately concentrated so that the capsule reaches a defined, usually higher percentage. This makes standardised extracts comparable and dosable, while raw powder naturally fluctuates. Anyone wanting to weigh forms and dosages cleanly against one another should therefore always look at the stated boswellic acid content and not just the milligram figure of the extract.

Bioavailability: why absorption plays a role

Boswellic acids are fat-soluble compounds - and, as with many fat-soluble plant substances, absorption from the gut is not automatically high. This explains why some manufacturers work with taking it alongside a fat-containing meal or rely on special extract forms intended to improve availability. For you as a buyer, this means: two products with the same milligram figure need not deliver the same amount that actually "arrives". A look at the extract form and the manufacturer's intake recommendation is therefore worthwhile. How the principle of fat solubility influences absorption in general is vividly explained by Bioavailability simply explained - and why fat helps with fat-soluble substances is also shown, using turmeric as an example, by Taking turmeric correctly.

Quality: what to look out for?

Since frankincense is a natural product, it is worth looking at several features when buying:

• Botanical species - for example Boswellia serrata, clearly declared.
• Standardised boswellic acid content - makes products comparable.
• Origin and independent laboratory testing for purity and contaminants.

What a laboratory certificate says is explained by Lab-tested: what does it mean?. At Scheunengut, we pay attention to lab-tested raw materials and transparent information on composition.

What research is investigating

Boswellia is the subject of scientific investigations; the focus here is on the boswellic acids and their biochemical properties. For the European Union, however, on the basis of the current assessment situation, no health claims under Regulation (EU) No 432/2012 are authorised. This means: we may not and do not wish to assert any effect - for instance in the area of joints - but describe Boswellia factually as a plant resin. This is an honest direction of research, not a proven benefit.

Boswellia in the context of other plant-based joint topics

Frankincense is not the only natural substance that people consider in the context of joints and mobility - and a comparison helps with the framing. Turmeric, with its marker compound curcumin, is often mentioned in the same breath (details in Turmeric & curcumin), as is the traditionally used devil's claw and the sulphur compound MSM. For all these substances, the same framework applies as for Boswellia: in the EU no health claims are authorised, which is why they are described factually in terms of origin, ingredients and quality. Anyone wishing to gain an overview of nutrients that contribute to bones and connective tissue with recognised functions will find it in Nutrients for the joints. In this way, Boswellia can be classified as one building block among several - soberly and without exaggeration.

Honestly framed, and a safety note

What is established are the origin, botany and characteristic marker-compound profile (boswellic acids) of frankincense. Not established - and not permitted as a claim in the EU - are concrete health effects. In the case of persistent complaints, especially in the area of the joints, a medical evaluation is the right course of action. If you take medication, are pregnant or breastfeeding, please also discuss use with a doctor.

Frequently asked questions (FAQ)

What actually is frankincense (Boswellia)?

Frankincense is the dried resin of trees of the genus Boswellia, which grow in the dry regions of North-East Africa, the Arabian Peninsula and India. For dietary supplements, Indian frankincense (Boswellia serrata) is usually used as a standardised extract.

What are boswellic acids?

Boswellic acids are a group of triterpenic acids and are regarded as the characteristic marker compounds of frankincense. High-quality extracts are standardised to a certain percentage of boswellic acids, which makes products comparable.

What should I look out for when buying Boswellia extract?

The precise botanical species (for example Boswellia serrata), the stated, standardised boswellic acid content, the origin, and an independent laboratory test for purity and contaminants. Since frankincense is a natural product with natural variations, transparent information is particularly important.

May a health effect be attributed to frankincense?

No. For frankincense (Boswellia), no health claims under Regulation (EU) No 432/2012 are authorised in the EU. It is therefore described factually in terms of origin, ingredients and quality. In the case of persistent complaints, such as in the joints, a medical evaluation is the right course of action.
