does lemon juice purify the kidneys
3. Lemon Juice. Naturally acidic, lemon juice has been shown to increase citrate levels in the urine, a factor that discourages kidney stones from forming. For a quick lemon kidney cleanse, squeeze 4-5 lemons into a quart of cold water and drink up. Or, for a warming beverage, squeeze one quarter to one half a lemon into 8 ounces of hot water daily.
