HelloPharmacist Scorecard of Eyebright Herb 450 mg 4:1 Extract 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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 30, 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: eyebright herb extract, concentrated at a 4:1 ratio, providing 450 mg per capsule. Eyebright has a long history in herbal medicine, traditionally used for eye health and respiratory comfort.

The capsule itself is made from gelatin and water, which are inactive ingredients that hold the extract together.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Eyebright product and its label doesn't state a use — see Eyebright's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for eyebright is limited. Our data shows insufficient reliable evidence to rate it for hay fever, common cold, cough, sore throat (pharyngitis), sinus inflammation (rhinosinusitis), or cancer.

That doesn't mean it doesn't work—it means the clinical trials we have on file aren't robust enough yet to say whether it does. If you're considering it for any of these uses, talk with your doctor or pharmacist about whether a trial makes sense for you.

The evidence, ingredient by ingredient Eyebright

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.

Eyebright is likely safe as a brewed tea in small amounts, but do not put homemade or non-sterile eyebright liquid directly into your eye—that carries real risk of harm. When taken by mouth, some people report confusion, headache, nausea, constipation, cough, shortness of breath, or nasal congestion, though these are not common.

The safety data isn't clear enough during pregnancy or breastfeeding, so it's best to avoid it at those times and discuss with your doctor or pharmacist if you're considering it.

Side effects, ingredient by ingredient Eyebright

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 — Eyebright.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 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.

If you take antidiabetes drugs—insulin, metformin, or any other medication to manage blood sugar—check your exact medications with the tool on this page or ask your doctor or pharmacist before you start. Eyebright may lower blood sugar and raise the risk of going too low.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Eyebright Herb may interest you if you're exploring herbal support for eye health or respiratory symptoms, but evidence for its effectiveness isn't strong yet. If you take insulin or other diabetes medications, check with your doctor or pharmacist before starting, because eyebright may lower your blood sugar further.

Talk it over with your healthcare provider to see if it's right for you and your situation.

Eyebright Herb 450 mg 4:1 Extract by TerraVita Premium Collection: Common Questions

Does Eyebright Herb 450 mg 4:1 Extract by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Eyebright Herb 450 mg 4:1 Extract has a known interaction with 86 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Eyebright Herb 450 mg 4:1 Extract 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 use eyebright drops in my eyes?
Not with this product, and not as an eyewash at home. Putting homemade or non-sterile eyebright directly in your eye is risky. This capsule is for oral use only.
What side effects should I watch for?
Some people report confusion, headache, nausea, constipation, cough, shortness of breath, or nasal congestion when taking eyebright by mouth. Stop and talk to your pharmacist if any of these bother you or don't go away.
Is it safe to take while pregnant or breastfeeding?
No. Safety data isn't established for pregnancy, and there isn't enough safety information during breastfeeding. Talk with your doctor or pharmacist before using it if you're pregnant, planning to become pregnant, or nursing.
Does eyebright actually work for hay fever or colds?
We don't have enough reliable evidence yet to say whether it does. The clinical data on file isn't strong enough to rate it for those uses or for cough, sore throat, sinus problems, or cancer.
Why do I need to check with my doctor if I take diabetes medication?
Eyebright may lower your blood sugar on its own. Combined with insulin or other diabetes drugs, that could push your blood sugar too low. Your doctor or pharmacist can help you figure out if it's safe for you and whether you'd need to monitor your blood sugar more closely.
