What is Usnic Acid ?

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. When extracted from the plant, it is yellow and crystalline in appearance. Mixed with water, however, it loses its yellow tint and appears colorless.
