    Function:

The entire lichen is used medicinally. Usnea looks like long, fuzzy strings hanging from trees in the forests In natural remedies, especially in the veterinary medicine, Usnic Acid is used in powders and ointments for the treatment of infections of the skin. Usnic acid as a pure substance has been formulated in creams, toothpaste, mouthwash, deodorants and sunscreen products, in some cases as an active principle, in others as a preservative.

     

    Application:

    Usnic acid is known to exhibit antibacterial properties. In the United States, usnic acid (as a powder or ointment) is used to treat primarily skin infections, and has been shown to be effective in treating tuberculosis bacteria, as well as other pathogenic fungi. Pure usnic acid is also used in many types of creams, toothpastes, deodorants and sunscreens as a protectant and a preservative. Externally, it has been used to treat conditions such as ringworm and athlete's foot. It is used both in humans and on animals.
