Usnea
Latin name : Usnea spp.
Hul'qumi'num name : Metth’unulhp
Usnea, often referred to as "old man's beard" or "tree moss," is a lichen that thrives within the Salish Sea bioregion, encompassing the coastal zones of British Columbia, Canada, and Washington State, USA. These unique Usnea species are readily spotted adorning the trees, especially conifers, in the lush coastal forests and islands of the area.
”This lichen grows on trees. The best way to harvest it is to let the winter storms bring it down to the ground for you. It shows up in grayish green bundles. To identify it, gently tug on a strand, if the core has a bit of elasticity to it, it is usnea. It had traditionally used as a pot scrubber but its qualities as healing strep throat and all sorts of chest and cough problems was realized only after the essential ingredients could be extracted with alcohol. This alcohol-based tincture will keep for years until needed.”

Usnea found in the Salish Sea region, like its counterparts elsewhere, contains various constituents, notably usnic acid. Usnic acid has demonstrated antimicrobial and antibacterial properties, making Usnea valuable for its potential medicinal applications. Indigenous peoples and traditional herbalists within the Salish Sea bioregion have historically harnessed the healing potential of Usnea. They employ it in diverse ways, including topically for treating skin conditions and wounds, as well as orally to address respiratory issues and infections.
