The main chemical compounds found in Icelandic Moss are large amounts of a type of starch called lichenin. When this compound is boiled, it turns into a substance resembling mucilage which is particularly soothing to irritated mucous membranes that line the respiratory tract and nasal passages. It also contains complex polysaccharides that have immunostimulant effects and is especially useful to counter catarrh and calm dry coughs. Icelandic Moss is classed as a bitter herb – it stimulates digestive enzymes and enhances the body’s ability to absorb nutrients whilst it is in itself a highly nutritious food. Do not use the product in case of individual intolerance How to brew tea: pour 1 teaspoon of moss with a glass of cold water and cook for 2-3 minutes until boiling. Take a little daily every 3 hours. Since the broth is quite bitter, bitterness can be eliminated by first soaking the moss in water.
