Kidney stones are crystals that form in the kidneys or the bladder. These crystals are composed of calcium salts, uric acid, or struvite, a kind of crystal that contains magnesium. A passed stone’s appearance is a clue to its composition. Calcium stones—the most common kind—may be mulberry-shaped. Uric acid stones are shaped like footballs and are reddish-brown or tan. Struvite stones are the color of maple syrup and are faceted.
- Use the Japanese beverage lisymachia or kinsenso tea, available from Japanese grocery stores, to increase urination and help the kidneys flush out small stones. Take 1 to 2 cups daily for three to four months.
- Eat adequate amounts of fiber. Low fiber consumption is associated with a high risk of stone development.
- Use any magnesium supplement that does not include calcium. Magnesium reduces the rate at which the digestive tract absorbs calcium and lowers the concentration of calcium in the urine.
- To avoid the formation of new stones, do not consume large amounts of alcohol or fat.
- Avoid high-protein and “crash” diets. They greatly increase the acidity of the urine, which can promote the development of some types of stones. Foods that drastically increase protein supply, such as protein powders, should be avoided while recovering from kidney stones.
- Limit vitamin C supplementation to between 2,000 and 4,000 milligrams daily for periods of no more than two weeks at a time, taking care to drink at least eight glasses of water daily. Higher dosages, continuous use of vitamin C, or use of vitamin C during periods of dehydration may contribute to stone formation.
- To prevent new calcium stones from forming, avoid dairy products, meats, beet greens, black tea, cocoa, cranberries, nuts, parsley, pepper, spinach, Swiss chard, and especially rhubarb.
- To prevent new uric acid stones from forming, avoid purine-rich foods, such as anchovies, herring, mackerel, sardines, shellfish, and yeast.
- Vitamin additions : Taking vitamin An and B6 supplement will certainly stop the formation of renal calculi and treat kidney stones permanently, that is, if it is taken for a few months. * Pomegranates : Seeds of pomegranates ( both sweet and sour ) have proved useful in treating renal calculi.
