Boswellia Serrata (Indian Frankincense)

Reviewed by the Nimbera editorial team · Last updated May 2026

Gupta et al. (1998), European Journal of Medical Research, n=80: a 6-week double-blind placebo-controlled RCT found 70% of patients taking 300 mg Boswellia gum resin three times daily showed measurable improvement in FEV1, FVC, peak expiratory flow rate, and eosinophil count, versus only 27% in the placebo group. PMID: 9810030.$15-35/month

How to use

Take a standardized extract providing 60-65% boswellic acids, typically 300-400 mg three times daily with meals. Look for products standardized to AKBA (acetyl-11-keto-beta-boswellic acid), the most pharmacologically active component. Allow 4-6 weeks of consistent use before evaluating effects.

How it works

Boswellic acids - particularly AKBA - selectively inhibit 5-lipoxygenase (5-LOX), the enzyme that converts arachidonic acid into pro-inflammatory leukotrienes (LTB4, LTC4) that drive airway inflammation and mucus hypersecretion in asthma.

Where to buy

Health food stores (Whole Foods, Sprouts), online retailers (Amazon, iHerb). Look for standardized extracts from reputable brands such as NOW Foods, Life Extension, or Jarrow Formulas. Verify the boswellic acid percentage on the label.

Typical cost: $15-35/month

Safety notes

May potentiate anticoagulants including warfarin and apixaban - two case reports document INR elevation when combined with warfarin; use with caution and monitor INR. Inhibits CYP3A4 and CYP2C9 in vitro, which may affect metabolism of certain medications - consult a pharmacist if you take any prescription drug. Can cause gastrointestinal upset (nausea, diarrhea) in some people; take with food. Avoid in pregnancy (insufficient safety data). Do not substitute for prescribed asthma controllers.
