Boswellic acids, the active terpenoid constituents of boswellia, may promote the activity of the enzyme 5-lipoxygenase, maintaining healthy leukotriene metabolism in tissues that surround the joints. In addition, boswellic acids may maintain healthy human leukocyte elastase enzyme activity, helping to maintain healthy connective tissue integrity. As a result of its effect on 5-lipoxygenase, boswellia may also play a key role in supporting healthy colon cell function.
