Origin & History
Norwegian Arctic Moss (Cetraria islandica), commonly known as Iceland Moss, is a lichen species native to the cold, northern regions of Norway and other subarctic climates. It thrives in nutrient-poor, acidic soils. This resilient organism is valued in functional nutrition for its unique polysaccharides and bitter compounds that support respiratory, digestive, and immune health.
“Norwegian Arctic Moss has been a vital part of traditional Norwegian and Nordic herbal medicine for centuries. Historically, it was used as a famine food and a potent remedy, valued for its ability to support respiratory health, boost immunity, and aid in digestion, particularly during harsh winter months.”Traditional Medicine
Scientific Research
Scientific studies on Norwegian Arctic Moss (Cetraria islandica) have primarily focused on its polysaccharide content, demonstrating immunomodulatory and anti-inflammatory effects in in vitro and animal models. Research also supports its traditional use for respiratory and digestive health, with some clinical evidence indicating its efficacy in soothing coughs and promoting appetite. Further human clinical trials are needed to fully establish dosage and long-term benefits.

Frequently Asked Questions
What is Norwegian Arctic Moss (Cetraria islandica)?
Also known as Iceland Moss, Cetraria islandica is a lichen (not a true moss) native to subarctic regions of Norway and Northern Europe. It contains unique polysaccharides and bitter compounds and has been used traditionally for centuries to support respiratory and digestive health.
What is the recommended dosage and is it safe?
Traditional use suggests 1-3 grams of dried lichen per day as tea, up to 4-6 grams daily for respiratory complaints. It is generally considered safe at these doses. People with stomach ulcers or those on immunosuppressant drugs should consult a healthcare provider before use.
What does the science say about Iceland Moss benefits?
In vitro and animal studies demonstrate immunomodulatory and anti-inflammatory properties from its polysaccharides. The European Medicines Agency recognizes it as a traditional herbal medicine for cough and throat irritation. However, robust human clinical trials are limited, and more research is needed to confirm therapeutic dosages.
