What is Uva Ursi?

Uva ursi is a plant. The leaves are used to make medicine.

Bears are particularly fond of the fruit, which explains its Latin name, "uva ursi," which means "bear's grape." Most authorities refer to Arctostaphylos uva-ursi as uva ursi. However, the related plants, Arctostaphylos adentricha and Arctostaphylos coactylis, have also been termed uva ursi by some experts.

Uva ursi is used primarily for urinary tract disorders, including infections of the kidney, bladder, and urethra; swelling (inflammation) of the urinary tract; increased urination; painful urination; and urine that contains excess uric acid or other acids. Uva ursi is also used for constipation and a lung condition called bronchitis.

Uva ursi, hops, and peppermint are also used in combination to treat people with compulsive bedwetting and painful urination.

Insufficient Evidence to Rate Effectiveness for...

  • Urinary tract infections (UTIs). Developing research suggests that taking a combination product containing both uva ursi and dandelion by mouth seems to reduce the recurrence rate of UTIs in women. However, since it is not clear if this kind of extended use is safe, do not use uva ursi for long-term prevention of UTIs.
  • Swelling of the bladder and urethra.
  • Swelling of the urinary tract.
  • Constipation.
  • Kidney infections.
  • Bronchitis.
  • Other conditions.
More evidence is needed to rate the effectiveness of uva ursi for these uses.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
