Lichens are a peculiar group of vegetal organism, which can be described as a symbiotic relationship between an algae and a fungus, that allow them to survive in extreme environmental conditions. Through the chlorophyllous synthesis, the algae feeds the organism with organic compounds, while the fungus, besides absorbing minerals and water from the ground, confers stability and a substrate used by the alga itself to grow.

Lichens possess specific bio metabolic paths that lead to the synthesis of a peculiar group of organic compounds, the lichenic acids, characterized by specific antimicrobial properties and utilised by the lichen to protect itself from the attack of bacteria, fungi and other foreign microorganism.1

Thanks to these properties, several lichens have been used in traditional medicine for years for making infusions and extracts. In particular, the use in ancient China and Arabia of extracts from the Usnea lichen species is documented in relation to the treatment of cutaneous infections.
