How to Cleanse Your Kidneys

Your kidneys serve the important function of filtering and managing the waste your body produces, so it’s essential to keep them healthy. Although detox diets and fasts have become increasingly popular, there is little scientific evidence to suggest that they can eliminate toxins from your body. Your liver and kidneys are very effective at doing this themselves, so you should concentrate on keeping these organs healthy, rather than fasting or detox dieting. Read on to learn how to cleanse your kidneys.

1. Eat Fruits and Vegetables

Potassium rich fruits and vegetables aid in cleansing your kidneys. Citrus fruits like grapes, oranges, sweet lime, cantaloupes, kiwis, bananas, apricots and prunes are all rich sources of potassium.

Including potassium rich fruits in your daily diet helps maintain the level of electrolytes in your blood which then keeps the kidney functioning at its optimum. A glass of grape juice consumed daily in the morning helps clear the build up of excess uric acid, a by product of kidney filtration.

Excessive intake of potassium can lead to a condition known as hyperkalemia which can cause a cardiac arrest. People who have kidney problems like kidney failure cannot have too much potassium. A healthy person is allowed to have up to 4.7 grams of potassium per day.

2. Drink Lots of Water

The most important thing for a regular kidney cleanse is to have a high intake of natural, clean water. Having 10-12 glasses of water per day helps to filter out the accumulated toxins.

A good indication of this would be passing clear urine. If the urine is anything deeper than a pale yellow, it means that you’re not drinking enough water. Fluids in the form of colas, coffees and aerated drinks are not a good substitute for water.

Different juices and teas have been advocated for the detoxification of kidneys. However, medically, it is only pure clean water that has been proven to help cleanse your kidneys.

3. Consume Cucumber Juice

The diuretic properties of cucumber may aid in flushing uric acid. As a result, cucumber juice will help dissolve kidney stone and improve overall kidney health.

  • Take 3-4 cups of cucumber pieces and juice them.
  • Drink this juice once or twice a day.
4. Eat Garlic

Garlic may stimulate urine production and may aid in flushing out toxins from the kidneys. It contains allicin, which oxidizes heavy metals and makes them more soluble in water, meaning that it can help to flush out toxins. There are several ways you can increase your garlic intake:

  • Eat garlic raw.
  • Add garlic to other food.
  • Take garlic supplements.
5. Incorporate More Barley into Your Diet

Barley is an excellent grain that is used to cleanse kidneys as well as to prevent kidney damage due to uncontrolled diabetes. Barley is a whole grain, and substituting barley flour in place of refined flours is a good way of including barley in your diet. Note that barley is not a cure, but just an adjunct along with other methods to maintain healthy kidneys.

Another way to get more barley is to soak a handful of barley in water at night and drink the same water first thing in the morning. This cleanses and repairs the build up of kidney toxins.

6. Eat Parsley

Parsley is considered to be a diuretic and makes you pee more. The more you pee, the more toxins or waste products are removed from the body. In other words, the more effective your kidney cleanse.

  • Parsley can be eaten raw or made into a juice or tea.
7. Eat Berries

Berries like cranberries help cleanse your kidneys. A cupful of cranberries is enough to cleanse the kidney each day. Cranberries contain a nutrient called quinine which converts itself into hippuric acid through a series of metabolic changes in the liver. Hippuric acid clears the excess buildup of urea and uric acid in the kidneys.

Scientific studies have proven that cranberry is also very useful in treating and preventing urinary tract infections.

8. Drink Lemon Juice

Lemon juice may be very effective in cleansing your kidneys. The citric content in lemons may reduce the level of calcium in your urine, thereby reducing the risk of kidney stones.

  • Juice a small lemon.
  • Add it to a cup of warm water.
  • Drink it in the morning on an empty stomach.
9. Avoid Protein

The only kind of food that has been proven to be detrimental to the kidneys is high-protein foods. They are harmful because their digestion and metabolism produce the highest amount of creatinine. If the creatinine levels go up, then there must be a problem in the filtering and eliminating function of the kidney. This is the main reason why creatinine is being measured in patients with kidney disease. For this reason, eat less protein to keep your creatinine levels down.

Talk to your doctor about this beforehand. Protein is a very important element of your diet and should not be avoided for most individuals.

10. Avoid Alcohol and Caffeine

Though scientists still argue about this, the possible list of things to avoid includes alcohol, caffeine, chocolate, nuts, and processed foods. Regardless of whether you’re cleansing your kidneys or not, it’s a good idea to limit your intake of all these things.

Alternative Medicine


Dandelion is rich in potassium and has a diuretic-like action, meaning it helps clear away excess water from the body. Hence, its very useful in increasing the urinary output.

Take about 15 drops of dandelion mother tincture 3 times a day. This is useful to cleanse your kidneys and can be safely continued for up to 6 months.


Gokshura is an Ayurvedic supplement which boosts kidney health and is beneficial to those who suffer from recurrent renal stones as well as recurrent urinary tract infections. It helps in maintaining the flow of urine and also cools and soothes the urinary membranes. It also possesses antibiotic properties and takes care of bladder infections.

  • A capsule of Gokshura can be consumed once or twice a day to maintain renal function.
Uva Ursi

Uva ursi is an excellent natural supplement for kidney cleanse. It helps repair the injury caused by kidney infections or kidney stones. It contains a glycoside known as arbutin which has anti-microbial properties, thereby also helping in treating urinary tract infections.


  • Kidney cleanse is not for people in poor health. It’s not a balanced diet, it’s not sustainable, and it has to be done correctly.
  • Certain supplements may not be good for you. To do this the most effective way, talk to a health professional.


  • Only two things are certain when it comes to detoxifying your kidneys: avoid high-protein food and drinks lots of water.
