What is "Usnea Acid"?

Usnea Acid (Usnic Acid) is a potent, "dual-edged" natural compound.

It is an excellent, evidence-based topical antimicrobial. For skin, wound, or oral infections, a commercially prepared cream, ointment, or mouthwash containing usnic acid is effective and safe when used as directed.

Lichen Extract Usnea Acid 98%" almost certainly refers to 98% Pure Usnic Acid, isolated and refined from lichens (often Usnea or other genera like Cladonia).

Key Properties and Traditional Uses
Antibacterial: Its most renowned property. Usnic acid disrupts bacterial cell membranes and inhibits mitochondrial respiration, making it effective against a range of Gram-positive bacteria like Staphylococcus aureus (including some MRSA strains) and Streptococcus pneumoniae.

Antifungal & Antiprotozoal: Shown to have activity against some pathogenic fungi and protozoa like Candida albicans and Leishmania species.

Antiviral: Some studies indicate activity against certain viruses, including influenza and herpes simplex virus (HSV).

Anti-inflammatory & Analgesic: Used topically to reduce swelling and pain in wounds, sprains, and infections.

Traditional & Modern Use:

Historically, Usnea was used across cultures (Europe, Asia, Americas) for wound dressing, treating respiratory infections (as a tincture or tea), and for gastrointestinal ailments.

Today, it's primarily found in topical applications (creams, ointments, gels) for skin infections, acne, athlete's foot, and in oral hygiene products (mouthwashes, toothpaste). Systemic (internal) use is much less common and requires caution.
