It won't hurt you if you don't have any. Why not be tested?? If you were exposed you can ask your doctor to run PCR test.
I personally prefer to know the truth.
If you are diagnosed and know the stage I'd refer you to http://www.medhelp.org/forums/hepatitis/wwwboard.html
where people with Hep C discuss and describe their experience and where there is RN (working with hepatologist) who is ready to advise. For free.
I refer you to hepatitis-c.de/hepace.htm (open Alternatives link)
I have a sibling with confirmed Hep C, read a lot, and talked to different "natural health" companies. The most honest didn't recommend their products for the cleansing I used myself. It's virus, not bacteria...
