Iceland moss (Cetraria islandica) — What it is and why people use it

Iceland moss is a lichen that grew into folk medicine across northern Europe. People used it for sore throats, coughs, and as a mild soothing food when other options were scarce. Today it’s sold as dried herb, tea, syrup, lozenges, and capsules. If you want a simple, soothing herb for a scratchy throat or mild cough, this guide tells you how to use it safely and how to choose a good product.

How to use Iceland moss

Powered by mucilage and polysaccharides, Iceland moss acts as a demulcent — it coats and soothes irritated mucous membranes. The most common home use is tea: add 1–2 teaspoons of shredded dried Iceland moss to a cup of water, bring to a low simmer for 5–10 minutes, strain, and drink warm. Take 1–3 cups per day when your throat feels raw.

For coughs, many people prefer syrup made by simmering the moss with water and honey or sugar until thick. Store syrup in the fridge and take a tablespoon as needed. Lozenges and throat pastilles use powdered moss mixed with honey and lemon and are handy for on-the-go relief. If you buy capsules or tinctures, follow the label—concentrations vary by product.

Practical tips and signs of quality

Look for suppliers who state the botanical name (Cetraria islandica) and show batch or lab testing when possible. Choose organic or sustainably wild-harvested sources; lichens grow slowly and overharvesting is a concern. Prefer single-ingredient products if you want to know exactly what you’re taking. Check the aroma and color of dried moss—fresh material smells faintly herbal and looks clean, not overly dark or dusty.

If you plan to prepare it yourself, shred the dried pieces before simmering so the mucilage releases better. Don’t boil aggressively; a gentle simmer preserves the soothing compounds. When making syrup, keep an eye on sugar content if you’re managing blood sugar—use smaller servings or talk to your provider about alternatives.

Some people use Iceland moss as a mild digestive aid or a gentle, nutritive addition to soups and porridges. It can add a slightly bitter, earthy note that pairs well with honey or citrus. Start small and notice how your body responds.

Always treat herbal remedies as supportive care. If symptoms are severe, persistent, or accompanied by fever, see a healthcare professional.
