Product description:Usnic
acid is a naturally occurring dibenzofuran derivative found in
several lichen species. It was first isolated by German scientist
W. Knop in ***4 and first synthesized between ********7 by Curd and
Robertson. Usnic acid was identified in many genera of lichens
including Usnea, Cladonia, Lecanora, Ramalina, Evernia, Parmelia
and Alectoria. Although it is generally believed that usnic acid is
exclusively restricted to lichens, in a few unconfirmed isolated
cases the compound was found in kombucha tea and non-lichenized
ascomycetes.
