During an acute episode of passing a stone, drinking warm water to which you’ve added liquid extract of wild yam can help calm muscular spasms of the ureter, allowing the stone to pass more easily.
Vitamin B6 and magnesium are key nutrients for preventing the formation of calcium stones, by far the most common kind. Magnesium reduces calcium absorption and lowers urinary oxalate. B6 works well with magnesium. Stone formation is associated with a deficiency of both these nutrients. Magnesium also makes it easier for the body to dissolve calcium oxalate (one form of calcium found in stones).
A daily tablespoonful of flaxseed oil or of flaxseeds themselves can be added to your salad or to a fruit smoothie. If you’re using the seeds, you will need to grind them fresh each day. Flaxseed can help reduce the amount of calcium in the urine.
Taking zinc inhibits the crystallization of minerals carried in the urine. (Zinc taken for the long term should be combined with copper.)
Cranberry, taken as juice or in capsules, acts to acidify urine and reduces the amount of ionized calcium in the urine, so is helpful to prevent both oxalate and uric acid stones from forming. You can also accomplish the same effect by drinking the juice of one lemon (diluted in water) each morning.
Traditionally, most doctors used to recommend restricting calcium intake for anyone prone to stones composed of calcium. But there is evidence that increasing calcium via supplements–for example, by taking calcium citrate–reduces stone formation by binding oxalate in the intestine so that it’s not absorbed into the urine.
Vitamin A in higher than normal doses is used during the week or so after the passage of a stone to help heal the mucous membrane lining of the ureter. After about a week, reducing the dose of vitamin A to a maintenance level helps discourage stone formation. However, try to increase your overall consumption of vitamin A-rich foods instead, including apricots, cantaloupe, carrots, sweet potatoes, and squash.
Drink lots of water. To help prevent recurrences, drink at least three quarts of water per day–more in hot, humid weather. If your urine is not virtually colorless, you’re not drinking enough water.
Reduce foods high in oxalate. Eat a healthy, balanced diet, but take it easy on asparagus, beets, beet greens, spinach, nuts, rhubarb, chocolate, and cola beverages.
Eat less meat. If you are a heavy meat eater, try to reduce your overall intake of animal protein. It encourages the body to excrete calcium, phosphorus, and uric acid in the kidneys.
Actually, the very best diet to prevent kidney stones is a basically a vegetarian one, high in a variety of fresh fruits and vegetables, whole grains, and void of animal protein and processed foods, with plenty of fresh water, juices and herbal teas.
Increase your potassium intake. Foods that contain potassium include bananas, orange juice, fresh fruit and vegetables. Low blood levels of potassium reduces levels of urinary citrate, which in turn raises levels of urine calcium. Like zinc, potassium is a potent inhibitor of calcium crystallization.
Get more magnesium in your diet. Many vegetables, grains, and fruits contain magnesium, including almonds, peanuts, brown rice, avocado, papaya, and prunes.
If your stone was found to be uric acid, avoid organ meats, sardines, anchovies, and brewer’s yeast. All of these are high in purines, which can elevate the uric acid in your blood and contribute to this type of stone formation.

speaking from experience here….LEMONAIDE!!!!! the citric acid in the lemons breaks down the stone…i didnt even feel it pass i had a 5×5mm stone and it broke it into little pieces..all i heard was the clank against the strainer they gave me. you need to drink at least 4 to 5 liters of fluid…teas and milk CAUSE the kidney stone.

I don’t know about dissolving them, but fiber is key in helping to prevent them. Fiber attaches itself to other things in the body and helps them “out”, because most fiber does not break down and digest. It is recommended that most healthy people get 25-35 grams of fiber per day. Most people don’t even get half of the minimum. Men should be on the upper echelon of that number.
