Usnea
© Martin WallHow It Works
Usnic acid gives usnea its bitter taste and also acts as an antibiotic in test tube studies.2 Test tube studies have suggested an anti-cancer activity for usnic acid. However, this action has not been sufficient to warrant further investigation in humans.3 Usnea also contains mucilage, which may be helpful in easing irritating coughs. Again, this has not been studied in humans.
How to Use It
Usnea, 100 mg three times per day, can be taken in capsules.4 Tincture, 3–4 ml three times per day, can also be used.
