HelloPharmacist Scorecard of Urinary System Support by Herb Pharm

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 5 active ingredients.
  • “Proprietary Extract Blend” is a proprietary blend — the label gives one combined amount (656 mg) without saying how much of each component you get.

This liquid blend contains five active herbal extracts: corn silk (fresh, undried), goldenrod flowering top (fresh, undried), uva ursi leaf, horsetail aerial parts (fresh, undried), and juniper berry. The product also holds a proprietary extract blend, whose individual components are listed separately.

Beyond these actives, the formula includes cane alcohol, distilled water, and glycerin as inactive ingredients.

Does it work?

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 system support.
  • We looked for evidence on: Kidney stones (nephrolithiasis), Nocturnal enuresis, Urinary incontinence, Urinary tract infections (UTIs), bladder health, urinary tract health — and 2 related terms.
  • The closest evidence on file: Uva Ursi is rated "Possibly Ineffective" for Urinary tract infections (UTIs) (Natural Medicines).
  • Also on file: Goldenrod is rated "Insufficient Reliable Evidence To Rate" for Kidney stones (nephrolithiasis), Urinary tract infections (UTIs).
  • Also on file: Corn Silk is rated "Insufficient Reliable Evidence To Rate" for Kidney stones (nephrolithiasis), Urinary tract infections (UTIs), Nocturnal enuresis.

The evidence we hold doesn't establish that any of these ingredients work reliably for their marketed urinary-support purpose. Corn silk, goldenrod, horsetail, and juniper all carry ratings of insufficient reliable evidence for the conditions they're traditionally used for—urinary tract infections, kidney stones, and benign prostate hyperplasia among them.

Uva ursi is actually rated possibly ineffective for urinary tract infections. Until better human research emerges, we can't say whether this blend delivers real benefit.

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 5 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Corn silk and goldenrod are generally well tolerated for short-term use, though human safety data are limited; corn silk may cause low potassium with prolonged use, and goldenrod can trigger allergic contact dermatitis in sensitive people. Uva ursi is well tolerated at low doses short-term but can be toxic at high doses or with long-term use, causing diarrhea, nausea, stomach upset, and vomiting—very high doses (30 grams or more) may be fatal.

Horsetail carries a real risk: crude horsetail contains an enzyme that depletes thiamine (vitamin B1) with prolonged use, and one case report linked this to autism in a child exposed during pregnancy. Juniper is generally tolerated in food amounts but may irritate the kidneys at medicinal doses and shouldn't be used long-term.

None of these ingredients have adequate safety data for pregnancy or breastfeeding; the safety notes advise against all five during pregnancy and breastfeeding.

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?
  • 5 of the 5 matched ingredients can interact with medications — Goldenrod, Corn Silk, Uva Ursi, Juniper, Horsetail.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 1,033 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 this product, double-check if you're on any HIV medications (especially NRTIs or efavirenz), blood pressure drugs, blood thinners like warfarin, diabetes medications, steroids, diuretics, lithium, liver enzyme substrates, or urinary acidifying agents. These are the drug classes most likely to interact, and the interactions can range from reduced drug effectiveness to serious electrolyte problems.

Uva-Ursi Leaf Extract6 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.

Likelihood Possible Evidence D

Corn Silk Extract, Fresh, Undried5 drug types · 290 drugs

Antidiabetes Drugs

Theoretically, taking corn silk with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research in diabetic mice shows that taking corn silk extract lowers fasting blood glucose levels.

Likelihood Possible Evidence D
Antihypertensive Drugs

Taking corn silk extract with antihypertensive drugs might increase the risk of hypotension.
Clinical research in both hypertensive and normotensive adults shows that taking corn silk extract lowers systolic and diastolic blood pressure.

Likelihood Possible Evidence D
Corticosteroids

Taking corn silk with corticosteroids might increase the risk of hypokalemia.
Clinical research shows that taking corn silk extract increases the urinary excretion of potassium.

Likelihood Possible Evidence D
Diuretic Drugs

Taking corn silk with diuretic drugs might increase the risk of adverse effects such as hyponatremia and hypokalemia.
Clinical research shows that taking corn silk extract increases urine volume and promotes the urinary excretion of sodium and potassium. Some patients may require electrolyte supplementation.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, suddenly stopping, starting, or changing corn silk treatment may alter the effects of warfarin.
Corn silk contains vitamin K. Individuals taking warfarin should consume a consistent daily amount of corn silk to maintain consistent anticoagulation.

Likelihood Likely Evidence D

Horsetail Aerial Parts Extract, Fresh, Undried5 drug types · 188 drugs

Antidiabetes Drugs

Theoretically, taking horsetail with antidiabetes drugs might increase the risk of hypoglycemia.
Equisetum myriochaetum has demonstrated hypoglycemic activity in clinical research. In an animal diabetic model, Equisetum giganteum had hypoglycemic effects. It is unclear whether other horsetail species have hypoglycemic effects.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, taking horsetail with diuretic drugs might increase potassium loss and the risk of hypokalemia.
Laboratory research shows that various species of horsetail have diuretic properties. Due to its diuretic effects, there has been concern that taking horsetail along with potassium-depleting diuretics might increase the risk for hypokalemia. However, pharmacokinetic research in humans shows that taking horsetail 900 mg daily for 4 days does not affect urinary excretion of electrolytes, including potassium and sodium, despite having a diuretic effect similar to taking hydrochlorothiazide 25 mg daily. It is unclear if taking horsetail for a longer duration would affect electrolyte levels. Until more is known, use with caution.

Likelihood Possible Evidence D
Efavirenz (Sustiva)

Theoretically, horsetail might decrease the levels and clinical effects of efavirenz.
In two case reports, patients were found to have detectable viral loads when taking horsetail-containing supplements along with an antiretroviral regimen that included efavirenz. In one case, the antiretroviral regimen included zidovudine, lamivudine, and efavirenz; in the other case, the regimen consisted of emtricitabine, tenofovir disoproxil fumarate, and efavirenz. One month after discontinuing horsetail, the viral loads became undetectable in both cases. The exact mechanism of this interaction is unknown. It is also unclear if this interaction is specific to efavirenz or if it is related to various components of antiretroviral therapy.

Likelihood Possible Evidence D
Lithium

Theoretically, horsetail might increase the levels and adverse effects of lithium.
Animal research suggests that horsetail has diuretic properties. Theoretically, due to these potential diuretic effects, horsetail might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Nucleoside Reverse Transcriptase Inhibitors (Nrtis)

Theoretically, horsetail might decrease the levels and clinical effects of NRTIs.
In two case reports, patients were found to have detectable viral loads when taking horsetail-containing supplements along with an antiretroviral therapy. In one case, the antiretroviral regimen included zidovudine, lamivudine, and efavirenz; in the other case, the regimen consisted of emtricitabine, tenofovir disoproxil fumarate, and efavirenz. One month after discontinuing the supplement, the viral loads became undetectable in both cases. The exact mechanism of these interactions is unknown. It is also unclear if these interactions are specific to NRTIs or if they are related to various components of antiretroviral therapy.

Likelihood Possible Evidence D

Juniper Berry Extract3 drug types · 162 drugs

Antidiabetes Drugs

Theoretically, taking juniper berry with antidiabetes medications might cause additive hypoglycemia.
Animal research shows that juniper berry can lower blood glucose.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, juniper berry might increase the risk of adverse effects from diuretic drugs.
Juniper berry is thought to have mild diuretic effects.

Likelihood Possible Evidence D
Lithium

Theoretically, juniper berry might reduce lithium excretion and increase serum levels of lithium.
Juniper berry is thought to have mild diuretic effects.

Likelihood Possible Evidence D

Urinary System Support by Herb Pharm: Common Questions

Does Urinary System Support by Herb Pharm interact with any medications?
Yes. Based on its ingredients, Urinary System Support has a known interaction with 1,032 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Urinary System Support contains 5 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
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.
Can I take this if I'm pregnant or breastfeeding?
The safety data don't support use during pregnancy—all five ingredients are advised against during pregnancy. For breastfeeding, there isn't enough information for any of them, so they're also advised against unless your doctor approves. Talk with your pharmacist or doctor about safer options for your situation.
What does uva ursi do in this blend?
Uva ursi is a leaf extract traditionally used in urinary formulas. However, the evidence we hold rates it possibly ineffective for urinary tract infections, so we don't have solid proof it works for what it's marketed to do.
Is this safe to use long-term?
No. Corn silk and goldenrod are labeled safe for short-term use only. Horsetail carries a risk of thiamine deficiency with prolonged use, and juniper can irritate the kidneys with long-term medicinal doses. These are short-term remedies only.
What are the common side effects?
Uva ursi may cause diarrhea, nausea, stomach upset, and vomiting. Horsetail may cause abdominal bloating, more frequent bowel movements, and nausea. Juniper may cause skin irritation topically, though oral side effects are uncommon at low doses. Serious effects are rare but possible at high doses.
What's the proprietary blend, and why isn't it fully listed?
The proprietary extract blend is a combination of ingredients the manufacturer doesn't disclose in full. We can only evaluate the five individual extracts listed separately; the blend itself is a container for some or all of those same ingredients.
Does this product have any ingredients with no interaction data?
No. All five active herbal extracts have documented interactions with medications. We hold interaction monographs for each of them, so check yours carefully against the search tool.
