HelloPharmacist Scorecard of Eyebright Alcohol Free by Herbal Terra

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: eyebright herb extract, a dry extract form of the eyebright plant. The inactive ingredients are glycerin and water, which serve as the liquid base.

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 allergic rhinitis (hay fever), cancer, common cold, cough, sore throat (pharyngitis), and sinus inflammation (rhinosinusitis).

That means we don't have enough solid trial data yet to say whether it works for these conditions — not that it doesn't work, just that the science isn't established enough in our records.

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.

Taken by mouth, eyebright is likely safe in small amounts as a tea, but we have reports of confusion, headache, nausea, constipation, cough, shortness of breath, and nasal congestion in some people. Don't put non-sterile eyebright directly in your eye — that carries risk of infection or irritation.

Safety data doesn't support use during pregnancy, so it's best avoided then. There isn't enough information to say it's safe while breastfeeding, so avoid it during that time too.

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, glyburide, or similar), double-check with your pharmacist before using this product. Eyebright may lower your blood sugar, raising the risk of hypoglycemia when combined with diabetes medication.

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 is generally well tolerated by mouth in small amounts, but the evidence for its effectiveness isn't solid yet. If you take diabetes medication, talk to your pharmacist before adding this product.

Stick to oral use and skip the eye-drop trick — and avoid it if you're pregnant or breastfeeding.
