Usnea Antibiotic Salve 1.5 oz.
Made of Usnea (Usnea sp.) and Cottonwood buds (Populus balsamifera) infused in virgin olive oil and thickened with beeswax.
Usnea, also known as old man's beard, is not a plant but lichen—a symbiotic relationship between an algae and a fungus. The entire lichen is used. The lichen helps the body to resist and kill unwanted organisms such as bacteria, virus, fungus and parasites. The properties are often referred to in a more specific way using the terms anti-bacterial, anti-biotic and anti-fungal. Usnea appears to kill bacteria by disrupting their metabolic function. Specifically, it uncouples oxidative phosphorylation by acting on the inner mitochondrial membrane and also has ATP-ase activity. Both of these mechanisms ultimately kill bacterial cells by cutting off their energy supply. Unlike bacterial cells, human cells are less permeable to usnic acid and are not adversely affected.
