The uva ursi herb, which is more commonly known as the bearberry is a small and evergreen shrub belonging to the plant order Ericacea. Bearberry is found growing mostly in sandy and gravel rich as well as dry soils, large populations can be found in many parts of continental Europe and in some areas along the northern regions of the continental U.S. - bearberry grows well in dry soils and grows at an optimal rate in soils composed mostly of sand and gravel. Morphologically, the shrub can be distinguished by the presence of a long and solitary fibrous main root that radiates out several buried and prostate stems in different directions, out of these prostate roots, arise the main aerial branching stems of the herb. These aerial stems can often reach four to six inches when they are fully grown. The bearberry has a slightly reddish or brown color bark on the stem. The small leaves of the bearberry are obovate to spatulate in shape and are rounded at the apex, they reach a length of about half an inch to one inch, and the leaves are also characterized by being slightly rolled down at the edges and also by the leathery feel. Bearberry leaves are ideally picked during the fall season.

Most of the herbal teas used and marketed in Europe for the herbal treatment of various kidney and urinary bladder disorders contain the bearberry as an active and essential ingredient. These herbal teas are extensively used in many places in Europe for the treatment of renal and bladder problems. When used correctly in different herbal preparations, the bearberry herb can prove to be an effective diuretic and may be used as a general urinary antiseptic. Self-treatment using the bearberry following self-examination of the disorder, depends on the herbal skills of the affected individual-ideally, an herbalist should be consulted even if a patient plans to eventually self-administer the herb for the treatment of simple urinary disorders.

Most regions in the northern atmospheres up to the Arctic borderlands have naturalized populations of the plant, though the bearberry shrub was originally native to continental Europe. Grasslands as well as heath lands in the northern hemisphere as well as shady undergrowths and damp conditions are preferred by the plant. Autumn is the season for the harvesting bearberry leaves in most areas where the plant is used in herbal medicine. During the autumn, the berries are also sometimes harvested along with the other parts of the plant, and though they are neither tasty nor particularly palatable, these berries are still used as minor fruits by people in some places.

All types of common kidney disorders can be very effectively treated using herbal remedies made from the bearberry or the manzanita herb. The leaves and the berries of bearberry can be used in the preparation of a herbal tea which can effectively help in the treatment of nephritis - which is the inflammation of the kidneys, this tea is also useful in the treatment of renal calculi – which are kidney stones. The herbal tea has also been used in the successful long term treatment of urethritis or inflammation of the urethra in women and in the treatment of cystitis, which is an uncomfortable inflammation affecting the urinary bladder of patients. Such physical disorders seem to be affected greatly by the strong astringent action of the tannin acid present in the berries and the leaves used in the tea - the powerful astringent action of the herbal tea enables the rapid treatment and alleviation of inflammation in internal organs of the urinogenital system.

Diseases affecting the kidneys and the urinary bladder are usually treated using the bearberry in the traditional folk medicine of many different European cultures, the bearberry herb has a very effective and strong diuretic action, at the same time it is also a good astringent - both qualities are desirable for the treatment of urinary or renal dysfunction in patients. 

The bearberry is believed to bring about a very effective antiseptic action on the urinary passages and it is also believed to help in toning the urinogenital system at the same time. Inflammatory disorders of the urinary tract such as cystitis and urethritis are believed to be treatable due to this strong antiseptic and toning effect of the herb. The principal antiseptic and astringent qualities possessed by the bearberry is due to the presence of an organic compound called hydroquinone in the herb, this compound is a chemical hydrolysis product of about five to twelve percent of a main precursor chemical compound called phenolic glycoside arbutin, which is present in the herb. The diuretic action evident in the plant is due to the combined effects of other chemical compounds such as the ursolic acid, which is a triterpene derivative, and a flavonoid pigment compound called isoquercitrin - these compounds together account for the strong diuretic action displayed by the herb. Large amounts of organic compounds called tannins are also present in the bearberry, these compounds may make up to fifteen to twenty percent of the plant extract and as these compounds tend to disturb the digestive process, they are regarded to be undesirable chemical constituents during treatment. 

The extraction process has to be designed in a particular way to offset the possibility of high tannin content, and for this reason, hot water should not be used to extract the herbal essence from the bearberry leaves - hot water is normally used in the preparation of the herbal tea, resulting in the extraction of high amounts of tannin from the leaves. To avoid this high tannin content tea, the leaves must be soaked in cold water and allowed to stand for twelve to twenty four hours prior to being boiled to make the herbal tea. As a result of this precautionary step, the total tannin content of the boiled beverage can be reduced drastically and the chances of a disrupted digestion can be avoided.
