Hello - Has anyone heard of silver intraveneously?
Does anyone know any doctors that do that? Does anyone know a good commercial brand of colloidal ilver that is not expensive? Thanks. I still have the ear infection, which I think is mastoiditis. The pathogens have been identified as Klebsiells oxytoca, and citrobacter freundii complex.--- both anamolous for the ear (mid-ear.)
