Boswellia

Anti-inflammatory mechanism: The most active Boswellia constituents (boswellic acids — especially 3-O-acetyl-11-keto-β-boswellic acid, AKBA) inhibit 5-lipoxygenase (5-LOX) and modulate NF-κB/COX-2 pathways, lowering leukotriene and prostaglandin mediated inflammation. This is a likely reason it could reduce intestinal inflammation associated with diverticular disease or flare-ups. Frontiers SpringerLink

Gut-specific rationale: Diverticular disease/SUDD often involves low-grade chronic mucosal inflammation and dysbiosis; anti-inflammatory botanicals that act in the gut (Boswellia, curcumin) have therefore been investigated as adjuncts to reduce symptoms and inflammation. However, diverticulitis can be infected/complicated (abscess, perforation), where antibiotics or surgery may be required — Boswellia is not a substitute for standard medical or surgical care in acute complicated disease.

Key points from clinical reports and product trials:

• Common clinical dosing used in trials: Many trials use standardized extracts containing known amounts of boswellic acids (often AKBA-enriched). One randomized Crohn’s maintenance trial used Boswelan: 3 × 2 capsules/day of 400 mg each (≈ 2400 mg/day total) for 52 weeks. Another acute/shorter trials commonly used ~300–1,200 mg/day divided (exact doses vary with formulation and AKBA content). Use products standardized for AKBA when possible because raw resin potency varies. Oxford Academic BioMed Central
• Combined formulations: For diverticular disease specifically, a published study evaluated a food-grade combined phytosome formulation of Curcuma longa (curcumin) + Boswellia serrata in symptomatic uncomplicated colonic diverticular disease — the combination aims for synergistic anti-inflammatory effects and improved absorption. If using Boswellia alone, choose a standardized extract (AKBA content stated). Drugs in Context jgld.ro
• Typical duration in studies: Shorter symptomatic improvement trials run 4–12 weeks; maintenance trials in IBD have lasted 6–52 weeks depending on endpoint. Improvement (if any) is usually assessed after several weeks — many botanical anti-inflammatories need at least 4–8 weeks to show effect. BioMed Central Oxford Academic

Practical (evidence-based) approach if someone plans to try it (informational — not medical advice):

• Use a standardized Boswellia extract (label states % AKBA or boswellic acids).
• Typical starting dose seen in evidence: 300–400 mg, two to three times daily (some studies used higher daily totals up to ~2,400 mg depending on capsule strength). Follow the product label and the doses actually used in any trial for that product. BioMed Central Oxford Academic
• Duration: allow at least 4–8 weeks to assess symptomatic benefit; for maintenance studies, protocols extended to months.
• Formulation choice: prefer extracts tested in clinical trials or third-party tested supplements — extracts titled “AKBA-enriched” (e.g., Boswelan®, 5-Loxin® variants) are commonly used in studies. Frontiers BioMed Central

IBD Journal (randomized trial) — Randomized, placebo-controlled, double-blind trial of Boswellia serrata extract (Boswelan) in maintaining remission in Crohn’s disease (108 patients; Boswelan 3×2 capsules/day; 52 weeks) — shows clinical interest and longer-term use in bowel inflammation, though this is Crohn’s rather than diverticulitis.
