Old Man’s Beard, Beard Lichen, and Treemoss.
Usnea is the generic and scientific name for several species of lichen in the family Parmeliaceae that generally grow hanging from tree branches, resembling grey or greenish hair. It is sometimes referred to commonly as Old Man’s Beard, Beard Lichen, or Treemoss. Usnea looks very similar to Spanish moss. Usnea grows all over the world. Like other lichens it is a symbiosis of a fungus and an alga. The fungus belongs to the division Ascomycota, while the alga is a member of the division Chlorophyta.
Usnea has been used medicinally for at least 1000 years. Usnic acid (C18H16O7), a potent antibiotic and antifungal agent is found in most species. This combined with the hairlike structure of the lichen, means that Usnea lent itself well to treating surface wounds when sterile gauze and modern antibiotics were unavailable. It is also edible and high in vitamin C.
In modern American herbal medicine, Usnea is primarily used in lung and upper respiratory tract infections, and urinary tract infections. There are no human clinical trials to either support or refute either practice, although in vitro research does strongly support Usnea’s antimicrobial properties.
Usnea also has shown usefulness in the treatment of difficult to treat fish infections in aquariums and ponds; in part due to the Usnic Acid for digestive internal infections or external infections, and as well for gill infections/stress due to Mucilage which is also contained in Usnea.
There is no formal scientific information on the safety or efficacy of oral use of Usnea, although its long history of use strongly suggests value.
