Common Uses

Uva Ursi is most often associated with the treatment of urinary tract infections, kidney stones and nephritis. In fact, until antibiotics were discovered, Uva Ursi was the primary method of treating such infections.

Uva Ursi reduces the amount of uric acid present in the body, which relieves pain associated with kidney stones and bladder infections. In addition, the diuretic and antiseptic properties of Uva Ursi work as anti-inflammatory agents, decreasing pain associated with bladder infections, kidney stones and urethritis.

Uva Ursi’s anti-bacterial properties are associated with arbutin and hydroquinone; these chemical properties make Uva Ursi useful in the treatment of urinary tract infections as well as in recurrent cystitis, an infection resistant to antibiotics in people such as paraplegics.

The Uva Ursi is a covering shrub and its leaves are the only part of the plant used for medicinal purposes. Uva Ursi can be purchased in the form of crushed leaves or powder preparations and dried herbs available in capsule form or for teas.
