Usnea barbata or Old man’s Beard is a lichen with a long history of being used in herbal medicine. We chose to come out with it as a tincture looking at it as a great anti-bacterial especially for respiratory infections. There are a number of active constituents found in usnea including those with antimicrobial, anti-oxidant and polyphenolic properties. It is most well known for treating certain types of infections, including those affecting the throat, respiratory tract, mouth, skin and urinary tract.
