I know a certain supplement that is call Kidney Care and everyone with kidney problems, severe or not, they are using or drinking it. There are people who got heal and there are lots who believes that this will help them from healing. Some says you can drink Barley powder. Barley powder doesn't only works with kidney, it even works on healing some problems with other organs. It even works with Cancer. Of course, doctors will not support this one but it really works on other people that is why people are doing the same. However, the great cure will always happen when one is drinking water as much as our body needs it. The right thing is to drink water now that we don't have kidney problem. I really wish you go with natural as alternative because it can really cure.
