HelloPharmacist Scorecard of Boswellia by Herb Pharm

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: Boswellia serrata oleo-gum-resin extract, a resin from the frankincense tree traditionally used to support joint and respiratory health. The liquid form also includes certified organic cane alcohol and distilled water as inactive ingredients.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: System restoration and joint support.
  • We looked for evidence on: Osteoarthritis, Rheumatoid arthritis (RA), Asthma, Crohn disease, Ulcerative colitis, Irritable bowel syndrome (IBS) — and 2 related terms.
  • The strongest evidence on file: Boswellia Serrata is rated "Possibly Effective" for Osteoarthritis (Natural Medicines).
  • Also on file: Boswellia Serrata is rated "Insufficient Reliable Evidence To Rate" for Asthma, Crohn disease, Ulcerative colitis, Irritable bowel syndrome (IBS), and more.

Boswellia serrata has possibly effective evidence for osteoarthritis — meaning some solid research supports it for joint discomfort and mobility. For hay fever, asthma, Alzheimer disease, and cluster headaches, the evidence we hold isn't established enough to rate it one way or the other.

The evidence, ingredient by ingredient Boswellia Serrata

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

When taken by mouth, Boswellia serrata extract is generally well tolerated short-term, though quality and dose vary widely between products. The most common side effects are abdominal pain, diarrhea, headache, heartburn, itching, and nausea.

Dizziness and vertigo have also been reported in some trials. A rare serious side effect is bezoar formation (a hard lump in the stomach) when very large amounts are swallowed.

The safety data advises against use during pregnancy and breastfeeding because there isn't enough information to know it's safe in those times.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Boswellia Serrata.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs.
  • For scale: 953 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this Boswellia, check with your doctor or pharmacist if you take any Moderate-severity CYP enzyme substrates: that means antidepressants, certain blood pressure and cholesterol drugs, heartburn medications, pain relievers, antihistamines, and cancer drugs. Also mention it if you take immunosuppressants.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Boswellia may help with osteoarthritis symptoms, but it interacts with a large number of medications through your liver's drug-processing system — so it's not something to add without checking first. If you take any regular prescription or over-the-counter medication, talk it over with your doctor or pharmacist before starting this product.

Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, Boswellia serrata might increase the levels of CYP1A2 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP1A2 enzymes.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, Boswellia serrata might increase the levels of CYP2C19 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP2C19 enzymes.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, Boswellia serrata might increase the levels of CYP2C9 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP2C9 enzymes.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, Boswellia serrata might increase the levels of CYP2D6 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP2D6 enzymes.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, Boswellia serrata might increase or decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that Boswellia serrata gum resin inhibits CYP3A4 enzymes. Other in vitro research shows that Boswellia serrata extract inhibits CYP3A4 enzymes at most concentrations, although it may modestly induce enzyme activity at low concentrations.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, Boswellia serrata might alter the effects of immunosuppressive drugs.
Some in vitro research suggests that Boswellia serrata extracts might inhibit mediators of autoimmune disorders such as leukotrienes and reduce production of antibodies and cell-mediated immunity. However, other in vitro research suggests that, when coupled with calcium ions, boswellic acids containing the keto group have immunostimulant properties within specific cell signaling pathways.

Boswellia by Herb Pharm: Common Questions

Does Boswellia by Herb Pharm interact with any medications?
Yes. Based on its ingredients, Boswellia has a known interaction with 952 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Boswellia contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this while pregnant or breastfeeding?
The safety data advises against use during pregnancy because there isn't enough information. During breastfeeding, safety is unknown, so it's best avoided then too. Talk with your doctor or pharmacist about your specific situation.
What are the common side effects?
Most people tolerate it well, but some experience abdominal pain, diarrhea, headache, heartburn, itching, or nausea. Dizziness and vertigo have also been reported. If you notice any of these, let your pharmacist know.
Does this actually work for arthritis?
Boswellia serrata has possibly effective evidence for osteoarthritis, meaning some solid research supports it for joint discomfort. For other conditions listed on the label, the evidence we hold isn't established enough to say whether it works.
Why is the ingredient a 'liquid' if Boswellia is a resin?
The Boswellia resin has been extracted and mixed into a liquid form with certified organic cane alcohol and distilled water, making it easier to take than the raw gum resin.
Is this product safe to use long-term?
The safety data we hold covers short-term use and notes that quality and dose vary widely between products. For long-term safety, talk with your doctor or pharmacist, since we don't have that information on file.
