Absolutely - especially when taken in large amounts and used in conjunction with the other recommendations in the Natural News article Grzz posted yesterday in the news forum on Hepatitis C. I can vouch for the article - I know the author rather well . . .
Utopia Silver has reports of their colloidal silver taking care of hep-c, Crohn's disease (I know the person who had Crohn's personally and will be doing an article on that soon), MRSA, ulcerative colitis, Lyme's, and much, much more.
I agree with Trapper - I would also include iodine. I am still learning about iodine and recently began taking it myself.
