Usnea, is a lichen that has traditionally been used in Chinese Medicine for centuries and aids in supporting the kidneys, respiratory system, as well as immune system. It is known for its cooling and drying properties while helping to eliminate heat, toxins and dampness. It can be used as a tincture, extracted or brewed into a tea to alleviate symptoms caused by colds and viruses. It can also turned into a powder or salve and used for its antibacterial and antifungal properties to clean wounds, treat skin conditions or treat athletes’ foot.
What is Usnea?
Usnea (Dolichousnea longissima, U. barbata, and U. californica) are lichens, a combination of Fungi and Algae that thrive on
host trees in pristine environments around the world.
Usnea is edible but commonly consumed as a liquid extract or applied topically. It can be made into herbal tea and has a variety of nicknames such as tree moss, beard moss, beard lichen, and old man’s beard.
You’ll often find Usnea growing in more pristine environments as it is sensitive to pollution and toxins in the air. It grows in abundance in The Scottish Highlands. If foraging we suggest rather than pulling it from trees collect it from branches or the ground where it has fallen. Do be sure to collect it away from roadsides and well-used pathways, as with all wild foraging, we advise that you take no more than is needed
