USNEA Usnea spp.
Liquid extract of dried tree lichen extracted with hot alcohol.
- Actions: Usnea's usnic acid has shown effective anti-microbial activity against fungus,
trichomonas protozoa, gram-positive bacteria (e.g., Staphylococcus, Streptococcus, and
Pneumonococcus, including penicillin resistant strains), and tuberculosis bacillus. Usnic acid
shows no antimicrobial activity against gram-negative bacteria (e.g., E. coli
and Salmonella). Increases resistance against colds and flu.
- Uses: Fungus infections (e.g., candidiasis, athlete's foot, ringworm); boils; impetigo; mastitis;
bronchial infections and pneumonia; sore throat or strep throat (gargle); sinus infections
(diluted spray); skin and lung tuberculosis; trichomoniasis; dysentery (but not typhoid,
cholera or other intestinal infections caused by gram-negative bacteria). Especially effective
against urinary tract infections and upper respiratory infections.
- Dose: Take 30 to 40 drops, 2 to 5 times per day. Topically apply full-strength extract if well
tolerated, or dilute with 1 or 2 parts water. As a gargle, mix drops in a little water and gargle
several times per day. As a nasal spray, mix 15 to 25 drops in half-cup saline solution and use 2
to 4 times per day.
- Cautions: None known.
