Boswellia

MODERATE EVIDENCEBotanicalLast updated April 2026

SCAN DOSE SUMMARY

Boswellia serrata extract contains boswellic acids — potent anti-inflammatory compounds that inhibit 5-lipoxygenase (5-LOX), a pathway not targeted by NSAIDs or COX inhibitors. Our research shows strong evidence for osteoarthritis pain relief and moderate evidence for inflammatory bowel disease. It works through a different mechanism than ibuprofen, making it a potential complement — not a replacement — for conventional anti-inflammatory therapy.

EVIDENCE GRADES

Osteoarthritis (knee pain)Strong — multiple RCTs (PMID: 25151215)
B+
Inflammatory bowel disease (UC/Crohn's)Moderate — limited but positive trials

WHAT IT DOES

Boswellic acids (AKBA — acetyl-11-keto-β-boswellic acid is the most active) specifically inhibit 5-lipoxygenase, the enzyme that produces leukotrienes. Leukotrienes are inflammatory mediators involved in asthma, allergies, and chronic inflammatory conditions. This mechanism is unique — NSAIDs target COX-1/COX-2, corticosteroids broadly suppress immune function, but boswellia specifically targets the 5-LOX pathway.

AKBA also inhibits NF-κB, human leukocyte elastase, and microsomal prostaglandin E2 synthase. The anti-inflammatory effect is potent but narrower than corticosteroids.

OPTIMAL DOSAGE

  • Standard Boswellia serrata extract (65% boswellic acids): 300-500mg 3x/day
  • 5-LOXIN/AprèsFlex (30% AKBA): 100-250mg/day
  • Aflapin (enriched AKBA): 100mg/day
  • Duration: 4-8 weeks for full anti-inflammatory effect
  • Take with fat — boswellic acids are lipophilic

DRUG INTERACTIONS

NSAIDs (ibuprofen, naproxen)Moderate

Different mechanism; may be additive anti-inflammatory but also additive GI risk

Anticoagulants (warfarin)Moderate

Boswellia has mild antiplatelet activity; case report of increased INR

CYP substrates (CYP1A2, CYP2C8, CYP2C9, CYP2D6, CYP3A4)Moderate

In vitro inhibition of multiple CYP enzymes — clinical significance unclear but exercise caution with narrow therapeutic index drugs

ImmunosuppressantsMinor

Anti-inflammatory properties may modulate immune function

SAFETY PROFILE

Drug Interactions

Side Effects

  • GI effects (nausea, acid reflux, diarrhea) — most common but milder than NSAIDs
  • Allergic skin reactions (rare)
  • Generally well tolerated — better GI profile than NSAIDs

Pregnancy & Lactation

  • Traditionally used in Ayurvedic medicine during pregnancy, but no modern safety data. Avoid supplemental doses.

WADA Status

Not Prohibited

HOW SCAN DOSE SCORES THIS

AKBA-standardized extracts (5-LOXIN, AprèsFlex, Aflapin) score highest
Products listing only "Boswellia extract" without boswellic acid % get flagged
For joint health stacks: synergistic with curcumin, collagen — score combination bonus
Warfarin users get automatic flag
CYP inhibition warning for users on multiple medications
