Iceland moss is a type of lichen consisting of a symbiosis of fungi and algae. They form a co-operative of the two species from which both benefit. The fungal part takes care of providing water and minerals, while the algal part forms biological material with the help of photosynthesis.
Iceland moss contains a high proportion of water-soluble polysaccharides together with special lichen acids that do not exist anywhere in nature except in lichens. Numerous scientific studies have been carried out on the efficacy of the above materials. The principal results are as follows:
Efficacy against bacteria
Efficacy against viruses
Efficacy against tumour growth
Strengthens the immune system
