The oddly named usnea isn’t a plant at all, but actually it is a lichen, which is a combination of algae and fungi functioning as a single organism. Usnea grows on old trees in cool, damp forests, most commonly found in the pacific Northwest which provides most of the nations supply. Usnea is an immune system tonic that can be used in acute situations as well as for long term immune enhancement and general prevention. It has no side effects or contraindications, and is safe for children and animals. It can be used along with or instead of Echinacea. Usnea is more specific for strep and staph infections than Echinacea, and its antibiotic properties are most specific to the respiratory and urinary systems. Use it to help heal respiratory and sinus infections, bronchitis, pneumonia, strep throat, colds, flues, as well as urinary tract, kidney, and bladder infections. Usnea is also beneficial for women with yeast infections, trichonomosas, bacterial vaginosis, and chlamydia. It can be helpful for people with chronic fatigue, HIV, herpes, and other chronic conditions related with depressed immunity.
