Botanical characteristic. Parmelia family. A perennial foliate-bushy lichen with a leathery thallus, 10-15 cm high. The thallus is attached to a tree, soil, and other substrate with the help of short filamentous trailers (rhizoids). From above the thallus is greenish-brown, from below it is light brown. In dry weather, it becomes brittle and brittle.

pharmacological properties. The presence of a bitter substance (centraric acid) in the thallus determines its properties as bitterness. Thallus also has an enveloping and antiseptic effect. The antibiotic usnic acid was isolated from the thallus, which even at a dilution of 1:2,000,000 has a bacteriostatic effect.
