• Lichen Islandicus Extractum is a complex mixture of lichen‑derived polysaccharides, phenolic acids and secondary metabolites. The polysaccharide fraction can interact with pattern‑recognition receptors on immune cells, leading to modulation of cytokine release. Phenolic compounds such as usnic acid exhibit free‑radical scavenging activity, reducing oxidative stress in tissues. Together, these actions may influence mucosal barrier function and support normal cellular metabolism and overall health.
