Usnea barbata
Hanging lichen of forests worldwide used in European, Chinese, and Native American folk medicine as powerful antimicrobial.
Usnea lichen (Usnea barbata) is a hanging lichen used globally in traditional medicine for its potent antimicrobial properties, primarily attributed to usnic acid. Modern research supports its use as an antimicrobial, anti-inflammatory, antifungal, and antiviral agent, with key active compounds including usnic acid, diffractic acid, and polyphenols.
Usnic acid exerts antimicrobial effects by inhibiting bacterial RNA polymerase and disrupting cell membrane integrity, leading to bactericidal activity. Anti-inflammatory actions involve inhibition of cyclooxygenase (COX) and lipoxygenase (LOX) pathways, reducing prostaglandin and leukotriene synthesis. Additionally, usnic acid modulates NF-κB signaling, decreasing pro-inflammatory cytokine production, while polyphenols provide antioxidant protection via free radical scavenging.
