HelloPharmacist Scorecard of Corn Silk Powder by TerraVita Premium Collection

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.

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.

Corn Silk Powder by TerraVita Premium Collection contains a single active ingredient: corn silk, a powder form of the silky threads from the corn ear. In traditional and botanical medicine, corn silk has been used to support urinary and cardiovascular function, though we hold no other inactive ingredients in this product.

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: urinary tract and bladder health support.
  • We looked for evidence on: Urinary tract infections (UTIs), Nocturnal enuresis, Prostatitis, Kidney stones (nephrolithiasis), Urinary retention, Overactive bladder — and 1 related terms.
  • The closest evidence on file: Corn Silk is rated "Insufficient Reliable Evidence To Rate" for Kidney stones (nephrolithiasis) (Natural Medicines).
  • Also on file: Corn Silk is rated "Insufficient Reliable Evidence To Rate" for Prostatitis, Urinary tract infections (UTIs), Nocturnal enuresis.

The evidence on corn silk's effectiveness isn't established in the data we hold. Our monograph rates it insufficient reliable evidence to rate for several conditions — angina, cardiovascular disease, congestive heart failure, depression, diabetes, and fatigue.

That doesn't mean it doesn't work; it means the clinical trials so far haven't been robust enough to say for certain one way or another.

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 hasn't been completed. The most common adverse effects reported are low potassium (hypokalemia) and low sodium (hyponatremia), especially with prolonged use.

Rarely, other side effects occur when taken by mouth. The safety data advises against corn silk during pregnancy.

While it's possibly safe during breastfeeding, there isn't enough data to know for sure, so check with your doctor or pharmacist before using it if you're nursing.

  • 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.

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 Powder may appeal to someone interested in traditional herbal support for circulation or urinary health, but it's not a casual supplement if you're on blood pressure, water pills, steroid, blood sugar, or blood thinner medications — all of those warrant a conversation with your pharmacist first. If you're pregnant or nursing, talk to your doctor or pharmacist before you start.

Corn Silk Powder by TerraVita Premium Collection: Common Questions

Does Corn Silk Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Corn Silk Powder 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 Powder 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.
Does corn silk powder actually work for anything?
The evidence isn't clear-cut in our data. We rate it insufficient reliable evidence for angina, heart disease, heart failure, depression, diabetes, and fatigue — which means the clinical trials haven't been solid enough to confirm whether it works.
Is corn silk safe if I'm pregnant?
No — the safety data advise against it during pregnancy because there's not enough reliable safety information. Talk to your doctor before using it.
Can I take it while breastfeeding?
Safety while breastfeeding is unknown. The data rate it possibly safe, but there isn't enough information to be certain either way. Check with your doctor or pharmacist for personalized advice.
What are the side effects I should watch for?
Adverse effects are rare, but the most common ones reported are low potassium and low sodium, especially if you use it long-term. Topically (on the skin), it can cause rash or hives, though you're taking this as a powder.
Why do I have to worry about my warfarin dosing if I use corn silk?
Corn silk contains vitamin K, which affects how warfarin works. If you suddenly start, stop, or change how much you take, it can throw off your blood thinner's effect. You need to keep your intake the same day to day.
