Product description:Usnea contain a antibacterial material and many other lichens, the antibacterial effect of usnic acid is particularly prominent, but due to poor usnic acid solubility in water, restrictions on the application, and compared usnic acid sodium usnic acid water-soluble effect is better.

Usnic acid is a naturally occurring dibenzofuran derivative found in several lichen species with the formula C18H16O7. It was first isolated by German scientist W. Knop in 1844 and first synthesized between 1933-1937 by Curd and Robertson.

Biological role in lichens:

Usnic acid is a secondary metabolite in lichens whose role has not been completely elucidated. It is believed that usnic acid protects the lichen from adverse effects of sunlight exposure and deters grazing animals with its bitter taste.
