Gravel root is a wonderful herb to use in cases of urinary tract stones (gravel), especially calcium salts, which tend to accumulate when the urine alkalinity or acidity changes. Gravel root is not only diruretic, causing an increase in the volume of the urine, but it is soothing to the mucous membranes of the urinary tract. A number of other herbs can be combined with Gravel rootto successfully treat kidney stones. These include such herbs as: Hydrangea root, Parsley seed, Stone root, or wild carrot. Other herbs, which are soothing to the urinary tract membranes, such as Corn silk, Marshmallow, Yerba mansa root, or couchgrass can be used with gravel root, and can help prevent further abrasion as the stone(s) make their way out of the urinary tract.

A tea of several of the preceeding herbs can be drunk by people who find they have a tendancy to form stones, as a preventative. It must be remembered, however, that lifestyle and diet changes might be appropriate to further prevent any recurrance of the stones. These things would include honestly evaluating your food intake, and to avoid foods which are high in oxalic acid, such as spinach and rhubarb; and foods which are excessive in uric acid, such as excessive meat. A great effort must be made to drink more water, as this is the basis for the formation of stones in the first place. If the urine is dilute as it passes through the tubules of the kidney, then there is much less of a tendency for the dissolved elements within it to fall out of solution. To achieve this, at least 2 quarts or a bit more than 2 litres of purified water are needed each day.. (hint: squeeze a half lemon per quart into it to flavor it and help it absorb into the body tissues. On the other hand, if the water intake is poor (a quart or less).. then the urine will be very concentrated with the dissolved elements. As the urine makes its way through the kidney, many more of these dissolved particles are likely to fall out of solution, and become the basis for further kidney stone formation. Note: Coffee should be avoided in cases where this herb is necessary.


A decoction of the tea is needed. Use 1 teaspoonful of herb per cup, add herb to cold water, bring to a boil, and simmer for 10 minutes, and take 1 cup three times per day.
