If you use the advice given by one of the best MDs we ever had in the USA, you would stop eating the day your body is not well and start a orange juice fasting until well. This works when done correctly and is the cheapest method I know of.
Herbally you can do many things, most kidney cleanse type herbs work well as do all normal herbs used for infections, etc. I always use one cure, cures all and that means you do what you have to do until your blood gets clean! Your blood then is the true cure, nothing else.
