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.
  • “Propretary Blend” is a proprietary blend — the label gives one combined amount (400 mg) without saying how much of each component you get.

Kidney Aid contains 5 active ingredients: horsetail, fenugreek, hydrangea, European goldenrod, and common plantain. Horsetail is traditionally used as a diuretic; fenugreek seed is used for blood sugar and sexual function support; hydrangea and goldenrod are also recognized for potential diuretic properties; and common plantain rounds out the blend.

The inactive ingredients are gelatin, cellulose, water, stearic acid, and magnesium stearate.

Does it work?

Insufficient evidence
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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: maintain healthy kidneys.
  • We looked for evidence on: Kidney stones (nephrolithiasis), Urinary tract infections (UTIs), Chronic kidney disease, Renal function, Urinary health.
  • The closest evidence on file: Goldenrod is rated "Insufficient Reliable Evidence To Rate" for Kidney stones (nephrolithiasis) (Natural Medicines).
  • Also on file: Goldenrod is rated "Insufficient Reliable Evidence To Rate" for Urinary tract infections (UTIs).
  • Also on file: Horsetail is rated "Insufficient Reliable Evidence To Rate" for Kidney stones (nephrolithiasis), Urinary tract infections (UTIs).

The evidence for these ingredients is limited. Horsetail shows insufficient reliable evidence for urinary incontinence, obesity, tonsillitis, and hair loss.

Fenugreek is possibly effective for sexual dysfunction, sexual arousal, dysmenorrhea, and diabetes. Hydrangea and goldenrod have no effectiveness ratings in our data.

For most of the uses this product implies—kidney support, kidney stones, or urinary tract health—the ingredients either have not been well studied or lack a clear evidence base.

The evidence, ingredient by ingredient Horsetail Fenugreek Hydrangea Goldenrod

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 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Horsetail is generally well tolerated short-term in healthy adults, but long-term use carries real risks. Crude horsetail contains thiaminase, which can deplete thiamine (vitamin B1) with prolonged use—though Canadian products must be certified free of thiaminase activity.

Common side effects include abdominal distension, increased bowel movements, and nausea. The safety data advises against horsetail in pregnancy and while breastfeeding.

Fenugreek is generally well tolerated in food amounts but supplement doses may cause abdominal pain, bloating, diarrhea, flatulence, and nausea; rare severe allergic reactions (angioedema, bronchospasm, shock) have been reported. The safety data advises against medicinal fenugreek in pregnancy, though limited evidence suggests it may be safe while breastfeeding.

Hydrangea and goldenrod have limited human safety data; large or prolonged doses may cause gastroenteritis, dizziness, or chest tightness (hydrangea), and both should be avoided in pregnancy and while breastfeeding due to insufficient data.

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?
  • 4 of the 4 matched ingredients can interact with medications — Goldenrod, Hydrangea, Fenugreek, Horsetail.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 423 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 Kidney Aid, check with your doctor or pharmacist if you take antidiabetes drugs (horsetail and fenugreek may lower blood sugar further), diuretic drugs (horsetail and goldenrod may worsen potassium loss), lithium (horsetail and hydrangea may raise lithium levels), blood thinners or antiplatelet drugs like warfarin or clopidogrel (fenugreek may increase bleeding risk), or HIV medications including NRTIs and efavirenz (horsetail may reduce their effectiveness). Also check if you take theophylline, phenytoin, sildenafil, or metoprolol—fenugreek may reduce how well these work.

Each ingredient & the kinds of drugs it affects

For each ingredient in Kidney Aid with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Fenugreek9 drug types · 389 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, fenugreek might have additive effects when used with anticoagulant or antiplatelet drugs.
Some of the constituents in fenugreek have antiplatelet effects in animal and in vitro research. However, common fenugreek products might not contain sufficient concentrations of these constituents for clinical effects. A clinical study in patients with coronary artery disease or diabetes shows that taking fenugreek seed powder 2.5 grams twice daily for 3 months does not affect platelet aggregation, fibrinolytic activity, or fibrinogen levels .

Likelihood Unlikely Evidence B
Antidiabetes Drugs

Theoretically, fenugreek seed might have additive hypoglycemic effects when used with antidiabetes drugs.
Clinical research shows that fenugreek seed can reduce fasting blood glucose and 2-hour postprandial glucose levels in adults with type 2 diabetes.

Likelihood Probable Evidence B
Clopidogrel (Plavix)

Theoretically, fenugreek seed might alter the clinical effects of clopidogrel by inhibiting its conversion to the active form.
Animal research shows that fenugreek seed 200 mg/kg daily for 14 days increases the maximum serum concentration of clopidogrel by 21%. It is unclear how this affects the pharmacokinetics of the active metabolite of clopidogrel; however, this study found that concomitant use of fenugreek seed and clopidogrel prolonged bleeding time by an additional 11%.

Likelihood Possible Evidence D
Metoprolol (Toprol)

Theoretically, fenugreek seed might have additive hypotensive effects when used with metoprolol.
Animal research shows that fenugreek seed 300 mg/kg daily for 2 weeks decreases systolic and diastolic blood pressure by 9% and 11%, respectively, when administered alone, and by 15% and 22%, respectively, when given with metoprolol 10 mg/kg.

Likelihood Probable Evidence B
Phenytoin (Dilantin)

Theoretically, fenugreek might decrease plasma levels of phenytoin.
Animal research shows that taking fenugreek seeds for 1 week decreases maximum concentrations and the area under the curve of a single dose of phenytoin by 44% and 72%, respectively. This seems to be related to increased clearance. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Sildenafil (Viagra)

Theoretically, concurrent use of sildenafil and fenugreek might reduce levels and therapeutic effects of sildenafil.
Animal research shows that taking fenugreek seeds for 1 week reduces maximum concentrations and the area under the curve of a single dose of sildenafil by 27% and 48%, respectively. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Theophylline

Theoretically, fenugreek may reduce the levels and clinical effects of theophylline.
Animal research shows that fenugreek 50 grams daily for 7 days reduces the maximum serum concentration (Cmax) of theophylline by 28% and the area under the plasma drug concentration-time curve (AUC) by 22%.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, fenugreek might have additive effects with warfarin and increase the international normalized ratio (INR).
Some fenugreek constituents have antiplatelet effects, although these might not be present in concentrations that are clinically significant. In one case report, a patient taking warfarin experienced an increased INR when starting to take fenugreek in combination with boldo.

Likelihood Possible Evidence D
Antihypertensive Drugs

Fenugreek may also have an additive effect on blood pressure-lowering medications. Studies on animals have shown that fenugreek seed can decrease both systolic and diastolic blood pressure by up to 22% when combined with metoprolol. Therefore, it is essential to monitor your blood pressure regularly if you are taking fenugreek and metoprolol together or any other antihypertensive drugs.

Likelihood Possible Evidence C
Fenugreek full monograph & interactions

Horsetail5 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.

Kidney Aid by RidgeCrest Herbals: Common Questions

Does Kidney Aid by RidgeCrest Herbals interact with any medications?
Yes. Based on its ingredients, Kidney Aid has a known interaction with 423 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Kidney Aid 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.
Is this safe to take if I'm pregnant or breastfeeding?
No. The safety data advises against horsetail and fenugreek in pregnancy due to insufficient data and potential effects on the uterus. Horsetail should also be avoided while breastfeeding. Fenugreek may be possibly safe while breastfeeding, but the evidence is limited. Talk with your doctor or pharmacist about whether this product is right for you.
Does horsetail actually help with kidney or urinary issues?
The evidence isn't established. Horsetail shows insufficient reliable evidence for urinary incontinence and other urinary tract concerns, so we can't say whether it works for these uses based on the data we hold.
What side effects might I experience?
The most common are abdominal distension, increased bowel movements, nausea (from horsetail), and abdominal pain, bloating, diarrhea, and gas (from fenugreek). Hydrangea may cause dizziness. Rare but serious allergic reactions—including swelling, wheezing, and bronchospasm—have been reported with fenugreek. Stop and seek help if you have severe allergic symptoms.
Can I take this long-term?
Horsetail is recommended only short-term in healthy adults; long-term use carries real risks, including thiamine depletion with crude horsetail. Hydrangea and goldenrod also have limited safety data for prolonged use. Talk with your doctor or pharmacist about how long is appropriate for you.
Does fenugreek work for sexual function?
Fenugreek is possibly effective for sexual dysfunction and sexual arousal according to the evidence we hold, though the data remain limited. Results vary, and it's worth discussing with your doctor if it's right for you.
What is common plantain in this blend for?
We don't hold interaction or safety data for common plantain, so we can't tell you what role it plays or how it might affect your medications. Check the product label or contact the manufacturer for more detail.
