Boswellic acid, a bioactive compound derived from the resin of the Boswellia species (frankincense), has been studied for its anti-inflammatory properties, which extend to support of the body's mucus membranes. Scientific interest centers on its ability to inhibit 5-lipoxygenase, an enzyme involved in inflammation and leukotriene synthesis, pathways implicated in many chronic inflammatory conditions affecting mucus membranes such as inflammatory bowel disease (IBD), asthma, and allergic rhinitis.

Clinical trials have provided moderate evidence for Boswellia extracts (which contain boswellic acids) in reducing symptoms and improving histological markers in ulcerative colitis, a form of IBD that affects the colonic mucosa. Several studies (e.g., Gupta et al., 2001; Gerhardt et al., 2001) have shown that standardized Boswellia extracts can reduce inflammation and promote healing of the gastrointestinal mucosa. Additionally, some in vitro and animal studies suggest protective effects of boswellic acids on respiratory tract mucus membranes by reducing inflammatory cytokine production.

However, while there is scientific support for Boswellia (and boswellic acid) in inflammation-related mucus membrane disorders, most evidence comes from small, short-term clinical studies and animal research. More robust, long-term human studies are needed to fully validate its effectiveness and safety for mucus membrane support across different organ systems.
