In the book of Prescription for Nutritional Healing Recommendations for Kidney stones:
-For pain relief, drink the juice of half a fresh lemon in 8 ounces of water every half-hour until the pain subsides. You can alternate between lemon juice and fresh apple juice.
-To maintain good kidney function, drink plenty of quality water-at least ten 8 –ounce glasses daily. By far the single most important measure one can take to prevent kidney stones from forming is to increase water consumption. Water dilutes urine and helps prevent concentrations of the minerals and salts that can form stones.(Chronic dehydration is a major risk factor in kidney stone disease.) Also, drink unsweetened cranberry juice to help acidify the urine (unless you are prone to uric acid stones). Drinkingthe juice of a fresh lemon in a glass of warm water first thing each morning can help prevent stones from forming. Lemon juice contains nearly five times the concentration of citric acid. One study showed people who consumed lemonade on a daily basis actually reduced stone recurrence.
-Increase your consumption of foods rich in Vitamin A. Vitamin A is beneficial to the urinary tract and helps to discourage the formation of stones. Good sources of vitamin A include alfalfa, apricots, cantaloupes, carrots, pumpkin, sweet potatoes, and squash.
-Use only distilled water for drinking and cooking. Add trace mineral droups to your drinking water.
-Minimize your consumption of animal protein, or eliminate if from your consumption of animal
protein, or eliminate it from your diet altogether. A diet high in animal protein causes the body to excrete calcium, producing excessive amounts of calcium, phosphorus, and uric acid in the kidneys and often resulting in painful kidney stones.
-Try drinking a large amount of liquid (preferably pure water), allow twenty minutes for digestion, and then run up and down stairs vigorously. This has been known to allow small, stubborn kidney stones to pass naturally.
-Avoid foods that contain or lead to the production of oxalic acid, including asparagus, beet greens, beets, blueberries, celery, eggs, fish, grapes, parsley, rhubarb, sorrel, spinach, swiss chard, and vegetables of the cabbage family. Also avoid alcohol, black tea(green tea is a good substitute), Chocolate, cocao, dried figs, nuts, pepper, and poppy seeds.
Caution: Green tea contains vitamin K, which can make anticoagulant medications less effective. Consult your health care professional if you are suing them. The caffeine in green tea could cause insomnia, anxiety, upset stomach, nausea, or diarrhea.
-stay active. People who are sedentary tend to accumulate high levels of calcium in the bloodstream. Exercise helps pull calcium from the blood into the bones, where it belongs.
And much more in the book, I am sorry I don’t have much time to write. Best wishes.
