My stepfather died from hep c. It took about 20yrs. One thing that I know for a fact helped him was Milk Thistle capsules.
His Dr. didn't know that he was taking them, but said, what ever it is you're doing, keep doing it, because you're better than the last time I saw you.
Once he started getting fluid in his midsection that they had to tap and drain out it was the end of the line. It looked like tea. His liver was stopping it's work and he didn't last a month.
