As the body consumes toxins, the kidneys become over burdened with acid wastes. Nephritis, uremia poisoning, and bladder problems are all acid related conditions which can be treated by the consumption of alkaline water. Kidney stones begin as tiny specks and they gradually build into solid stones, composed of phosphates, urates and others. They are another form of acidic salts. Drinking plenty of alkaline water will prevent kidney stones from forming, and even after their formation, it can dissolve them. Japanese doctors have used alkaline water for years to treat the kidneys.
