Why Cleanse the Kidneys?

Located near the middle of your back, your kidneys are a pair of bean-shaped organs responsible for clearing waste from your body.

Each day, your kidneys process about 200 quarts of blood to help remove about two quarts of excess water and waste products.

Approximately 26 million people in the U.S. suffer from chronic kidney disease and over 35 million have some type of bladder disease. The challenge with kidney disease is that many times individuals do not experience symptoms before they develop advanced kidney disease or renal failure.

The kidneys also release three important hormones: erythropoietin (which stimulates the bone marrow to make red blood cells), renin (which regulates blood pressure), calcitriol (the active form of vitamin D, which helps maintain calcium for bones and for normal chemical balance in the body).

The main components of this cleanse include:

  1. PRL Renaven capsules - made into a tea
  2. PRL Uriven capsules- made into a tea
  3. PRL Cardio-ND - helps support your kidneys, clean up the blood, and kill off any unwanted pathogens

Directions for your Kidney Cleanse:

The kidney is actually self-cleansing if you consume adequate fluids, which can take the form of foods such as fruits and vegetables as well as pure water and other liquids. It is good to periodically give your kidneys some help in flushing themselves with kidney-boosting herbs.

Steps for completing your basic kidney cleanse:

  1. Make the KIDNEY TEA: Every morning, make a kidney-cleansing tea. Open up your dosed amounts of Kidney Complex and Bladder Complex into a 24 oz glass. An average daily dosage of each product during cleansing is 6-10 caps of each. Pour hot water over the herbs and cover tightly. Let steep for 10 minutes. Uncover and let cool and strain. Sip on this tea throughout the day, preferably between meals. This tea will work on softening up kidney sludge and supporting the kidneys in cleansing themselves. It is common to see the urine darken a bit while drinking this tea.
  2. Add CARDIO-ND: After your tea has cooled, add your dosed amount of Cardio-ND to your tea and sip on it throughout the day. Feel free to add a bit of sweetener or flavor to your tea to make it more palatable.

Length of the Cleanse:

Continue this cleanse for at least 6 weeks. It is recommended to cleanse your kidneys at least once per year. Some individuals choose to cleanse their major detox organs once per season.

Nutritional Guidelines During your Kidney Cleanse:

  1. REDUCE ANIMAL PROTEIN - Reduce your intake of animal protein. Excess protein in the diet is very stressful to the kidneys.
  2. REDUCE SUGAR, REFINED SALT, & PROCESSED FOOD - Reduce your intake of dairy, caffeine, alcohol, carbonated beverages, sports drinks, sweets, chocolate, processed foods that contain preservatives, artificial sweeteners, table salt, synthetic vitamins, etc.
  3. INCREASE INTAKE OF WHOLE FOODS - Increase your intake of fresh, organic foods such as organic vegetables, legumes, and grains.
  4. HYDRATE - Drink at least half of your body weight in ounces of pure, filtered water. For example, if you weigh 150 pounds, drink at least 75 ounces of water each day. Your urine should be a pale yellow color.
  5. WATERMELON SEED TEA - Watermelon seed tea is a diuretic recommended in the Edgar Cayce readings, particularly as a stimulant to cleanse and purify the kidneys and bladder. Edgar Cayce is one of the most well-known and respected medical intuitives of all time. At least once a day, three days a week, take watermelon seed tea prepared by pouring a pint of boiling water over a tablespoonful of watermelon seed (ground or cut) and allowing it to steep. Let it cool, then strain and drink. If practical, the tea should be made fresh for each use.

These suggestions are also great to follow long-term to keep your kidneys strong and healthy.

Kidney Stones:

A kidney stone is a hard mass that forms from crystals that have separated from the urine within the urinary tract. In most cases, kidney stones develop because calcium oxalate within the urine has crystallized.

Kidney Stone Symptoms:

Usually marked by extreme pain in the area of the kidneys or in the lower abdomen, kidney stones may also cause difficulty urinating, blood in the urine, nausea, and fever.

Preventing Kidney Stones:

Although there's no evidence that a kidney flush can help prevent kidney stones, you might reduce your risk by drinking lots of water and cutting back on sodium. People with a history of kidney stones may also want to avoid foods rich in oxalate, such as chocolate, okra, sweet potatoes, sesame seeds, greens, nuts, and spinach.

Kidney Stones and Calcium:

Despite claims to the contrary, research shows that a high intake of calcium through foods may decrease risk for kidney stones. However, taking calcium in supplement form may increase risk.
