Old Man's Beard
Usnea is best known as an immune tonic and anti microbial which is particularly good for lung diseases. It is best used as an alcohol extract or tincture. Many of these properties are due to the content of usnic acid found in this symbiotic organism. Although usnea has been shown to increase bleeding times it can still be used as a wound dressing in an emergency. Its web-like structure makes it useful to help hold a wound together in an emergency and prevent infection.
