Medicinal Actions & Uses

Stone root has diuretic and tonic properties, and is chiefly employed in the treatment of kidney stones. It is also prescribed to counteract fluid retention. It has been used to reduce back pressure in the veins, which in turn helps prevent the formation or worsening of hemorrhoids and varicose veins.

As an astringent, stone root contracts the inner lining of the intestines, and can be helpful in treating disorders of the digestive system such as irritable bowel syndrome and mucous colitis. The fresh leaves or roots of stone root are applied as a poultice to bruises and sores.
