Origin and structure

• Usnic acid is a lichenic acid present in a wide number of species and varieties of lichens including genus Usnea, Cladonia,Cetraria and Parmelia.
• Several lichens have been used in the past in traditional medicine for making infusions and extracts. In particular, in ancient China and Arabia the use of Usnea lichen extracts for the treatment of cutaneous infections is documented.
• Usnea barbata, vulgarly called “olds man’s beard”, for its wide diff usion and being a not protected lichen species, represents the primary source for the industrial production of usnic acid.
• Usnic acid possesses strong antibacterial properties probably associated to its peculiar chemical structure.
• However, its poor solubility profi le in most of the solvents regularly used by the cosmetic industry, narrows its use in cosmetic products.
• The salification of usnic acid with sodium salts lead to an improved solubility, maintaining the same activity profile.
• Th e resulting active ingredient is denominated Evosina® (Sodium Usnate).
