They filter our blood, removing toxins and waste. This is then passed to the bladder and out of the body. In our modern society, with our water conditions, our intestines become a self-poisoning system. As the molds, bad bacteria and parasites breed in our intestines they produce poisons that put a large strain on the kidneys. This is not the only source of toxins.
Lets look at our environment and see what is there that causes our kidneys to be overloaded.
When we clean our homes, it is very important to inspect our closets to see what we are using. Take the labels and look up all these chemicals - you will be shocked. As you clean, you breathe in the substances you spray. The things you use on your hands are also a source of poison going into your body. The kidneys need to remove these poisons from your blood and get rid of them.
