Sambucol...elderberry kills flu virus. Stock up, folks.
There was a long thread quite active for a while - "Avian Flu Preparedness Thread". There was a long discussion about the utility of elderberries. Maybe someone can dredge up a link or you can do a search. The problem with eldeberries is they stimulate the immune system (apparently) which may not be a good thing with this flu. Unless it can keep someone from getting the flu in the first place.
There are opinions all over the place on this.
