What is it
Boswellic acids are the main active triterpenoid compounds in the resin of Boswellia (frankincense) trees, with 11-keto-beta-boswellic acid (KBA) and acetyl-11-keto-beta-boswellic acid (AKBA) considered the most bioactive. They inhibit 5-lipoxygenase and other inflammatory pathways and are used mainly for joint and inflammatory conditions.

osteoarthritis pain
Disease adjunctMultiple small-to-moderate RCTs and pooled analyses report that standardized Boswellia/boswellic acid extracts reduce osteoarthritis pain and stiffness and improve function versus placebo. Trials are generally short, vary in extract standardization, and some are industry-sponsored, so effect sizes are uncertain. The signal is consistent enough to rate good but not strong.
Bottom line: A reasonable evidence-based adjunct for knee osteoarthritis, with modest expected benefit.
Evidence is mixed
Benefits are reproducible across small trials but limited by short duration, heterogeneous extracts, and frequent industry funding.
