The organism: Iceland Moss (Cetraria islandica)
Iceland moss is neither a moss nor a plant, but a lichen – a unique organism formed by the symbiosis of a fungus and an alga living together. It belongs to the Parmeliaceae family and grows in subarctic and alpine regions across Europe, particularly in Iceland, Scandinavia and the Alps. It grows on soil and rocks in open, cool, humid environments.
The thallus – the body of the lichen – has a leathery, branching appearance, brownish-green in colour, and reaches a height of 3-12 cm. The name Cetraria derives from the Latin cetra (small shield), describing the flattened shape of the thallus branches. The name islandica refers to Iceland, where the lichen is particularly abundant and where it was traditionally used as food during famines, thanks to its polysaccharide content.
The thallus is harvested in summer, when climatic conditions allow optimal growth.

How to use
Dosage: 5-10 drops in a glass of water or tea, twice daily.
