Boswellia
Boswellia serrata (Frankincense)
Boswellia serrata, commonly known as Indian frankincense, is a resinous tree extract used primarily for its potent anti-inflammatory properties in conditions such as osteoarthritis, inflammatory bowel disease, and asthma. The active constituents are boswellic acids, particularly AKBA (3-O-acetyl-11-keto-β-boswellic acid), which are responsible for its therapeutic effects. It is widely used as a natural alternative or adjunct to NSAIDs for chronic inflammatory conditions.
Mechanism of Action
Boswellic acids, especially AKBA, selectively inhibit 5-lipoxygenase (5-LOX), the enzyme responsible for synthesizing pro-inflammatory leukotrienes, without significantly inhibiting cyclooxygenase (COX) enzymes, distinguishing its profile from traditional NSAIDs. AKBA also inhibits microsomal prostaglandin E synthase-1 (mPGES-1) and suppresses NF-κB signaling, reducing downstream production of pro-inflammatory cytokines such as TNF-α and IL-1β. Additionally, it has been shown to inhibit complement activation and reduce degradation of glycosaminoglycans in cartilage tissue.

Dosing Protocols
With meals to improve absorption and reduce gastrointestinal discomfort
Standardized extracts should contain a minimum of 30-40% total boswellic acids and at least 10% AKBA. Some formulations use phospholipid complexes (e.g., Phytosome) for enhanced bioavailability, allowing lower doses of 100-250mg twice daily. Effects typically become noticeable after 4-8 weeks of consistent use.
Safety & Side Effects
Boswellia has a well-established safety profile with decades of traditional and clinical use; it is generally well-tolerated at recommended doses with adverse effects being mostly mild and gastrointestinal in nature. However, it should be used cautiously in pregnant women (may stimulate uterine contractions), individuals with liver conditions, and those on anticoagulant or antiplatelet therapy due to potential interactions.
Possible Side Effects
- !Gastrointestinal discomfort including nausea, bloating, or diarrhea, particularly on an empty stomach
- !Acid reflux or heartburn at higher doses
- !Skin rash or allergic dermatitis in sensitive individuals
- !Mild abdominal cramping during initial use
- !Headache, reported infrequently
- !Liver enzyme elevation with prolonged high-dose use (rare, monitor with chronic use)
Interactions
- -May potentiate anticoagulant and antiplatelet drugs (warfarin, clopidogrel, aspirin), increasing bleeding risk
- -May enhance hypoglycemic effects of diabetes medications, requiring blood glucose monitoring
- -Can inhibit CYP2C9 and CYP3A4 enzymes at high doses, potentially altering metabolism of statins, immunosuppressants, and certain antiepileptics
- -Additive anti-inflammatory effects when combined with NSAIDs or corticosteroids — may allow dose reduction of pharmaceutical agents but increases monitoring need
- -May reduce efficacy of P-glycoprotein substrate drugs by modulating intestinal transporter activity
Cost & Where to Buy
Standard boswellic acid extracts are inexpensive; cost increases significantly for patented enhanced-bioavailability formulations such as ApresFlex (AKBA-enriched) or Phytosome complexes. Price also varies based on AKBA and total boswellic acid standardization percentage.
