Here in Scotland I have direct access to the sea. I am well aware of the health benefits of sea weeds to us humans and in use as an organic fertilizer. Personally I do not like the stuff. However I do wonder of what benefit if any this would be to the birds and then the soil as I compost for my garden? Then there is silver nitrate which is also a natural antibacterial agent. I believe it was an initial source of silver nitrate for photographic film. (Oh I'm a physicist, not a chemist) :/ What I do know is that if I were to use is to blanch in fresh boiling water then dry, due to Norovirus. Yeah I know if we have nuclear fallout my wee friends would be protected... lol Anyone?
