A short, evidence-based look at Boswellia serrata supplements in inflammatory bowel disease — explained by a UK-trained gastroenterologist in Dubai.
Why patients ask about Boswellia serrata
Patients with inflammatory bowel disease often ask about supplements, and Boswellia serrata is one that comes up regularly in clinic. When a patient with ulcerative colitis recently told me he was keen to try it, it prompted me to look more closely at the evidence. Rather than dismissing the idea, I reviewed what we actually know and how to approach a trial safely.
What is Boswellia serrata?
Boswellia serrata is a plant-derived extract obtained from the resin of the Boswellia tree. The resin contains active compounds known as boswellic acids, which have anti-inflammatory properties.
How does Boswellia work?
Boswellia primarily influences leukotriene-driven inflammation (via the 5-lipoxygenase pathway). This is different from NSAIDs, which act through cyclo-oxygenase pathways. Because of this difference, Boswellia does not cause NSAID-type gastric injury, although mild gastrointestinal upset can still occur in some individuals.
Ulcerative colitis: what does the evidence show?
There is some evidence from small clinical studies suggesting Boswellia serrata may help mild ulcerative colitis in the short term. The evidence base is limited, but it is not unreasonable to consider as an adjunct option in selected patients who are stable and monitored.
Crohn’s disease: what does the evidence show?
Current research does not show a proven benefit for Boswellia serrata in maintaining remission in Crohn’s disease. Patients should not rely on it instead of evidence-based medical therapy.
Safety and side effects
Boswellia is generally well tolerated. The most commonly reported side effects are mild gastrointestinal symptoms such as bloating, nausea, or loose stools. Supplement quality varies, so it is sensible to keep your care team informed when adding any supplement alongside IBD treatment.
My practical advice for patients who want to trial it
If a patient with mild ulcerative colitis is keen to trial Boswellia, I do not automatically say no. I prefer a monitored approach: note the exact start date, keep the IBD team informed, and adjust monitoring if required — especially if there are other medical conditions or multiple treatments in the background.
Take-home summary- Ulcerative colitis: some evidence in mild disease (adjunct option)
- Crohn’s disease: no proven benefit shown
- Supplements should support care, not replace it
- Let your IBD team know so monitoring can be adjusted if needed
Frequently asked questions
What is Boswellia serrata?
Boswellia serrata is a plant-derived extract obtained from the resin of the Boswellia tree. It contains boswellic acids with anti-inflammatory effects.
Does Boswellia serrata help ulcerative colitis?
There is some evidence from small clinical studies suggesting Boswellia may help mild ulcerative colitis in the short term. Evidence is limited, so it should be considered only as an adjunct in selected patients.
Does Boswellia serrata work for Crohn’s disease?
Current research does not show a proven benefit for maintaining remission in Crohn’s disease. It should not be relied on as a treatment strategy for Crohn’s disease.
Can Boswellia irritate the stomach like NSAIDs?
Boswellia works through different inflammatory pathways than NSAIDs and does not cause NSAID-type gastric injury, although mild gastrointestinal upset can still occur.
What side effects can Boswellia cause?
The most common side effects are mild gastrointestinal symptoms such as bloating, nausea, or loose stools.
