A resin from the Indian frankincense tree.
Why it’s used: Traditionally used to support joint comfort.
Boswellia is a gum resin from Boswellia serrata, the Indian frankincense tree, which grows in the dry hills of India. When the bark is cut, it weeps a fragrant resin that hardens into pale tears. Related species give us the frankincense used in incense and perfume.
In Ayurveda, where it is known as salai guggul, boswellia resin has traditionally been used to support joint comfort. Its main compounds of interest are boswellic acids, including one called AKBA (acetyl-11-keto-beta-boswellic acid). Researchers have studied boswellia extracts in small trials looking at joint comfort and mobility, and while some results are encouraging, the evidence is still limited and it has no authorised health claim.
On labels you will see boswellia, Boswellia serrata gum resin extract, Indian frankincense or a branded extract name. Many extracts are standardised to a percentage of boswellic acids or AKBA, which is the most useful figure for comparing products, since raw resin and concentrated extracts differ a lot.

A meta-analysis of 7 randomised controlled trials with 545 patients found improvements in pain, stiffness and function scores; the authors suggest at least 4 weeks' use.
This meta-analysis of 11 randomised trials (1,009 people) of curcuminoid or boswellia products found both beat placebo for pain and function; study quality was low overall.
80 adults with knee osteoarthritis took 100 mg/day of a Boswellia serrata extract (Aflapin) or placebo for 180 days. Pain and function scores improved versus placebo, with no safety changes.

Boswellia is a resin from the Indian frankincense tree, Boswellia serrata. It has a long history in Ayurveda, where it is traditionally used to support joint comfort. Supplements use extracts concentrated in boswellic acids, especially one called AKBA.
AKBA stands for acetyl-11-keto-beta-boswellic acid, one of the boswellic acids researchers are most interested in. Extracts are often standardised to a percentage of AKBA or total boswellic acids, which is a better way to compare products than the extract weight alone.
They are closely related. Boswellia serrata is known as Indian frankincense, while the frankincense used in incense mostly comes from other Boswellia species. Supplements use Boswellia serrata resin extract, which is taken by mouth rather than burned or used as an essential oil.
