Cetraria islandica
Subarctic lichen used in Scandinavian and Icelandic medicine for respiratory conditions; mucilage soothes mucous membranes.
Iceland Moss (Cetraria islandica) is a subarctic lichen traditionally used in Scandinavian and Icelandic medicine as a demulcent expectorant for respiratory conditions and as a digestive bitter. Its key bioactive compounds include cetraric acid, fumarprotocetraric acid, lichenin, isolichenin, and mucilage, which contribute to its soothing, antimicrobial, and bitter tonic properties. Evidence for its efficacy is limited (Level C), primarily based on traditional use and preliminary studies.
The polysaccharides lichenin and isolichenin form a mucilaginous layer upon contact with mucous membranes, providing a demulcent and soothing effect that reduces irritation and facilitates expectoration. Bitter compounds such as cetraric acid stimulate taste receptor TAS2R family, increasing salivary and gastric secretions, thereby acting as a digestive bitter. Additionally, fumarprotocetraric acid exhibits antimicrobial activity against respiratory pathogens, possibly through disruption of bacterial cell walls, while the overall anti-inflammatory action may involve inhibition of cyclooxygenase and lipoxygenase pathways.
