Hi All,
There is one of the best silver colloids avilable it is Argyrol and it is available from
www.argyrol.com I recomend getting the 1 oz. bottle. it will pretty well get rid of sinusitus infections and illiminate ever having sinus surgury for the most part.

Invive.com is another source of mild silver protien as well. they have a page that tells the truth about silver colloids the real science and the math.
