I have updated the Aquarium/Pond Answers artcle.
"As a natural antibiotic it has also proven effective against gram positive bacteria, such as Mycobacterium tuberculosis (making Usnea a great alternative to Isoniazid).
Scientists believe that usnic acid works by disrupting cellular metabolism, either by preventing the formation of ATP which is the cells' energy source or by the stopping the action of oxidative phosphorylization. Usnea may also be a better choice than the drug metronidazole (as per human studies) for parasites and anaerobic bacterial treatments in aquariums.
Usnea contains potent antibiotic properties on gram positive bacteria.
As well, the Usnic acid found therein has shown antiviral, anti-protozoal, anti-inflammatory and analgesic (pain killer) activity.
It is also noteworthy that Usnea is edible, with no known toxic side effects from ingestion in animal and human studies and as well is an excellent source of Vitamin C.
In fact some monkeys consume similar lichens as their primary diet. Reference: Golden snub-nosed monkey
More information about Usnea;
Test tube studies have suggested an anti-cancer and an anti-viral activity for usnic acid. This may also make Usnea useful for the hard to treat aquatic viral disease; Lymphocystis (which is usually not fatal in otherwise healthy fish). The human studies can also be transferred to fish for tumors. I personally have not tested this enough as of writing this article, but based on human studies and the few tests I have done, Usnic acid shows promise here."
