(+)-Usnic acid

Usnic acid is extracted from Usnea.  Also known as old man's beard, Usnea is not a plant but a lichen—a symbiotic relationship between an algae and a fungus.  The entire lichen is used medicinally.  Usnea looks like long, fuzzy strings hanging from forest trees.  In natural remedies, especially in veterinary medicine, Usnic Acid is used in powders and ointments for the treatment of skin infections.  Usnic acid as a pure substance has been formulated in creams, toothpastes, mouthwashes, deodorants and sunscreen products, and in some cases as an active principle, while in others as a preservative.
