Uva Ursi

Uva Ursi

(Arctostaphylos uva-urs)

Use(s) or Purpose(s)

  • Orally, uva ursi is used for urinary tract infections (UTIs), inflammatory conditions of the efferent urinary tract, cystitis, urethritis, diuresis, constipation, lithuria, dysuria, acidic urine, pyelonephritis, benign prostatic hyperplasia (BPH), and bronchitis.
  • In combination, an herbal preparation containing uva ursi, hops, and peppermint is used to treat people with compulsive, strangury enuresis and painful urination.

Risk Information

Caution(s) and Warning(s)
When used orally long-term. There is some concern about the safety of long-term use because of the hydroquinone constituent of uva ursi. Hydroquinone can have mutagenic and carcinogenic effects, and long-term use might result in significant adverse effects. In one report, a 56-year-old female developed bull's-eye maculopathy, paracentral scotomas, and retinal thinning after 3 years of uva ursi tea ingestion. This is thought to be due to decreased melanin metabolism. Hydroquinone in uva ursi inhibits melanin production. Tell patients to avoid long-term use of uva ursi.
PREGNANCY:  Uva ursi can have oxytocic effects; avoid using.

Contraindication(s)
Uva ursi is thought to have diuretic properties. Theoretically, due to these potential diuretic effects, uva ursi might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.
COLORIMETRIC URINE TESTS: Theoretically, uva ursi can interfere with colorimetric urine tests and can turn urine greenish-brown.
RETINAL THINNING: Uva ursi contains hydroquinone which inhibits melanin synthesis and might lead to retinal thinning. Theoretically, uva ursi might worsen retinal thinning in patients with this condition. Long-term use of uva ursi should be avoided in these patients.

Known Adverse Reaction(s)
Orally, uva ursi can cause nausea, vomiting, gastrointestinal discomfort, and a greenish-brown discoloration of the urine.
Large amounts can be oxytocic, increasing the rapidity of labor.
One gram of hydroquinone, equivalent to 6-20 grams of uva ursi, can cause tinnitus, nausea, vomiting, shortness of breath, cyanosis, convulsions, delirium, and collapse. Five grams of hydroquinone, equivalent to 30-100 grams of uva ursi, can cause death.
Other adverse effects due to uva ursi include hepatotoxicity and irritation and inflammation of the urinary tract mucous membranes. Chronic use, especially in children, can cause liver impairment due to its tannin content.
A case has been reported of retinal thinning, bull's-eye maculopathy, and paracentral scotomas in a 56-year-old female after 3 years of uva ursi tea ingestion. This is likely due to decreased ocular melanin synthesis. The hydroquinone constituent of uva ursi inhibits melanin production.
