Full disclosure
Ingredient Transparency · database check

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Uva Ursi by Earthborn Elements is a single-ingredient supplement made from Arctostaphylos uva ursi, a plant traditionally used for urinary tract health. The capsule itself is gelatin.

That's it — just the herb and the capsule material.

Does it work?

Leans against
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Leans against

The strongest graded evidence we hold for the stated purpose leans against a benefit.

Why this rating?
  • The label markets this product for: urinary tract health support.
  • We looked for evidence on: Urinary tract infections (UTIs), urinary discomfort, kidney health, urinary system.
  • The closest evidence on file: Uva Ursi is rated "Possibly Ineffective" for Urinary tract infections (UTIs) (Natural Medicines).

The evidence for uva ursi's effectiveness is mixed. For urinary tract infections (UTIs), the data rates it as possibly ineffective.

For bronchitis and benign prostatic hyperplasia (BPH), there isn't enough reliable evidence to say whether it works or not. If you're taking this for a specific reason, talk with us about whether the research supports its use for your situation.

The evidence, ingredient by ingredient Uva Ursi

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Uva ursi is generally well tolerated at low doses and used short-term. Most common side effects are stomach upset — nausea, vomiting, diarrhea, and stomach irritation.

At very high doses (20 grams or more of dried herb), serious effects like convulsions, delirium, and shortness of breath have been reported, and doses of 30 grams or more may be fatal. Avoid using this supplement during pregnancy — it may stimulate the uterus and we don't have safety data.

Don't use it while breastfeeding either, since there isn't enough information to know it's safe.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Uva Ursi.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: lithium.
  • For scale: 804 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking uva ursi, double-check any medication your liver processes through CYP2C19 or CYP3A4 (a very common pathway — ask us if you're unsure), drugs cleared by glucuronidation, lithium, medications that acidify your urine, and any drug transported by P-glycoprotein. Your pharmacist can tell you quickly if yours are on the list.

The bottom line

Scorecard at a glanceFully disclosed formula with graded evidence leaning against its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Uva ursi is worth considering if you're looking for short-term urinary tract support, but the evidence is weak for UTIs specifically. If you take any prescription medications — especially those metabolized by your liver or lithium — check with us first.

Pregnant or breastfeeding? Skip this one.

Keep doses low and don't use it long-term.

Arctostaphylos uva ursi6 drug types · 803 drugs

Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, uva ursi may decrease the metabolism of CYP2C19 substrates.
In vitro, uva ursi appears to inhibit cytochrome CYP2C19. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, uva ursi may decrease the metabolism of CYP3A4 substrates.
In vitro, uva ursi appears to inhibit CYP3A4. This effect has not been reported in humans.

Likelihood Possible Evidence D
Glucuronidated Drugs

Theoretically, uva ursi may increase levels of drugs metabolized by glucuronidation.
In vitro, uva ursi extract appears to strongly inhibit UDP-glucuronosyltransferase (UGT) 1A1 (UGT1A1). However, uva ursi extract does not appear to inhibit UGT1A1 in animal models. This effect has not been reported in humans.

Likelihood Possible Evidence D
Lithium

Theoretically, uva ursi may increase lithium levels, necessitating a decrease in dose.
Uva ursi may have diuretic properties. Diuretics may increase lithium reabsorption with sodium in the proximal tubule of the kidney. Theoretically, uva ursi might reduce excretion and increase levels of lithium.

Likelihood Probable Evidence D
Urinary Acidifying Agents

Effects of uva ursi in the urinary tract may be reduced by urinary acidifying agents.
Uva ursi seems to work best in alkaline urine. Theoretically, taking uva ursi with medications known to acidify the urine may decrease any effects of uva ursi on the urinary tract.

Likelihood Possible Evidence D
P-Glycoprotein Substrates

Theoretically, uva ursi may alter the levels of drugs transported by P-glycoprotein.
In vitro, uva ursi appears to inhibit the multi-drug transporter protein, P-glycoprotein. This effect has not been reported in humans.

The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.

At normal doses, uva ursi is generally well tolerated. The most common side effects are stomach-related: nausea, vomiting, diarrhea, and general stomach upset. These are usually mild.

How long can I take this?
Uva ursi is meant for short-term use only. Don't use it long-term or at high doses — the supplement can be toxic with prolonged or excessive use.
What is uva ursi used for?
Uva ursi is traditionally used for urinary tract health. However, it's also been studied for bronchitis and benign prostatic hyperplasia (enlarged prostate), though the evidence for those uses isn't strong enough to rate yet.
