If you consume adequate fluids, vegetable and fruit juices, and especially water, the kidneys are self-cleansing.
But, many herbs can improve kidney function. Most herbs do so in preventing common kidney and urinary-tract infections or by acting as a diuretic to flush out excess fluid and kidney stones. Some herbs act in more of a preventive capacity, some in an ongoing health-boosting capacity and others as treatments of existing kidney problems.
There are also foods and vitamins that are useful in cleansing the kidneys. These are included below.
