HelloPharmacist Scorecard of Corn Silk 1,200 mg by Nature's Way

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

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.

This product contains one active ingredient: corn silk (the stigma and styles from corn cobs), supplied at 1,200 mg per capsule. Corn silk has a long history in traditional medicine, particularly for urinary and cardiovascular concerns.

The capsule itself is made from hypromellose (a plant-based coating), with magnesium stearate added as a flow agent during manufacturing.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Corn Silk's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Traditional support for urinary health.
  • We looked for evidence on: Nocturnal enuresis, Prostatitis, Urinary tract infections (UTIs), Urinary tract irritation, Bladder health, Kidney support — and 1 related terms.
  • The closest evidence on file: Corn Silk is rated "Insufficient Reliable Evidence To Rate" for Prostatitis (Natural Medicines).
  • Also on file: Corn Silk is rated "Insufficient Reliable Evidence To Rate" for Urinary tract infections (UTIs), Nocturnal enuresis.

The evidence we hold for corn silk does not establish that it works for any of its traditional uses — angina, heart disease, heart failure, depression, diabetes, or fatigue all carry a rating of insufficient reliable evidence. That means the research so far hasn't given us a clear answer either way.

If you're considering corn silk for any of these conditions, talk with your doctor about whether it makes sense for your situation.

The evidence, ingredient by ingredient Corn Silk

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.

Corn silk is generally well tolerated for short-term use, but human safety data are limited and a thorough safety evaluation has not been done. The most common concerns with oral use are low potassium (hypokalemia) and low sodium (hyponatremia), especially with prolonged use.

Adverse effects overall seem rare, though they haven't been exhaustively studied. During pregnancy, there isn't enough reliable safety data, so it's best avoided.

While breastfeeding, safety is unknown — only use it if a clinician approves. If applied to skin, corn silk can occasionally cause irritation (dermatitis) or hives (urticaria).

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 — Corn Silk.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 290 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 you start, check your exact medications against these drug types: blood pressure medications (antihypertensive drugs), water pills (diuretics), diabetes drugs, corticosteroids, and warfarin. All carry Moderate interaction risks with corn silk.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Corn Silk by Nature's Way is generally well tolerated for short-term use, but it's not proven to work for any condition we have data on. If you take blood pressure pills, water pills, diabetes drugs, corticosteroids, or warfarin, this product isn't a simple add-on — you need to check with your pharmacist first.

Skip it in pregnancy, and get approval from your clinician before using it while breastfeeding.

Corn Silk 1,200 mg by Nature's Way: Common Questions

Does Corn Silk 1,200 mg by Nature's Way interact with any medications?
Yes. Based on its ingredients, Corn Silk 1,200 mg has a known interaction with 290 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Corn Silk 1,200 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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 corn silk if I'm on a blood pressure medication?
Not without checking first. Corn silk lowers blood pressure on its own, so combining it with blood pressure drugs could drop your pressure too low. Talk to your pharmacist — they can look at your specific medication and dose to figure out if it's safe for you.
Does corn silk really help with diabetes or heart disease?
The evidence we have isn't strong enough to say. Animal studies suggest corn silk might lower blood sugar, but we don't have reliable human evidence yet for diabetes — or for heart disease, angina, heart failure, depression, or fatigue. Don't rely on it as a treatment without your doctor's input.
What are the most common side effects?
Low potassium and low sodium are the main concerns, especially with long-term use. Adverse effects seem to be rare overall, but the full safety picture hasn't been thoroughly studied. If you feel weak, have muscle cramps, or feel dizzy, mention it to your pharmacist or doctor.
Is corn silk safe during pregnancy?
No — there isn't enough reliable safety data, so it's best avoided when you're pregnant. Talk with your doctor about what's safe for you during pregnancy.
Can I use it while breastfeeding?
Safety while breastfeeding is unknown. Only use it if a clinician approves and is monitoring you. Check with your doctor or pharmacist first.
I take warfarin — can I use this?
Corn silk contains vitamin K, which warfarin is sensitive to. You can use it, but only if you keep the amount you take consistent every day — sudden changes could throw off how well your blood thinner works. Talk to your pharmacist about the right approach for you.
