    Usnea has been used in Chinese medicine for more than three thousand years. Early Chinese herbalists administered usnea orally as an expectorant and topically to treat infections and ulcers. Today, it is used as a tincture or infusion to treat tuberculosis and bronchitis, and applied locally to help heal infected wounds. 

    · Usnic Acid from RD Health Ingredients®

    Usnic acid is a type of chemical extracted from usnea, a type of lichen also known as old man's beard, because of its resemblance to human facial hair. Usnic acid is known to exhibit antibacterial properties. In USA, usnic acid (as a powder or ointment) is used to treat primarily skin infections, and has been proved to be effective in treating tuberculosis bacteria, and other pathogenic fungi. Pure usnic acid can be used in many types of creams, toothpastes, deodorants and sunscreens as a protectant and a preservative.
