There are many delivery methods (follow that link) including using a nebulizer to get the silver into your bloodstream via your lungs. Please do read all about it at http://SILVERengines.com.

Regarding Flu-Ban, perhaps you could compound a reasonable substitute if you can get the ingredients? Here's a photo of the label on the jar. Unfortunately, the exact proportions are unknown, but you may be able to find dosage suggestions for the individual ingredients?
