Cetraria islandica - Iceland moss

Cetraria islandica, commonly known as Iceland moss, is a lichen that grows in cold, mountainous, and Arctic regions across Europe, Asia, and North America. Despite its common name, it is a lichen rather than a true moss. It has been used for centuries in traditional medicine to help soothe coughs and support digestion, and it has also served as a food source during times of scarcity. Today, Cetraria islandica is valued for its bioactive compounds and is commonly found in herbal teas, cough remedies, and dietary supplements.
