HelloPharmacist Scorecard of Eyebright Extract Powder 500 mg by BulkSupplements.com

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 Aerial Part Extract, 500 mg per serving. Eyebright is a plant used traditionally to support eye and respiratory health, though modern evidence for these uses is still developing.

The product contains no inactive fillers or other ingredients.

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 Eyebright's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: eye health and comfort.
  • We looked for evidence on: Asthenopia (eye strain), Conjunctivitis, Allergic rhinitis (hay fever), eye irritation, eye redness, nasal congestion.
  • The closest evidence on file: Eyebright is rated "Insufficient Reliable Evidence To Rate" for Allergic rhinitis (hay fever) (Natural Medicines).
  • Also on file: Eyebright is rated "Insufficient Reliable Evidence To Rate" for Asthenopia (eye strain), Conjunctivitis.

The evidence for eyebright's effectiveness is not yet established for the conditions on file. The data we hold shows insufficient reliable evidence to rate it for allergic rhinitis (hay fever), cancer, common cold, cough, pharyngitis, and rhinosinusitis.

That doesn't mean it doesn't work — it means rigorous human studies haven't proven it yet. If you're considering eyebright for a specific health goal, talk with a pharmacist or doctor about what the current evidence actually supports.

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 — such as a tea — though some people have reported headache, confusion, nausea, and constipation. A few have also reported cough, shortness of breath, and nasal congestion.

Safety during pregnancy has not been established; the data advises against use during pregnancy. There isn't enough safety information to use this product while breastfeeding — talk with your doctor or pharmacist for personalized advice.

One important caution: using homemade or non-sterile preparations directly in the eye is risky; stick to oral forms only.

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 any antidiabetes drugs — insulin, metformin, or others — check this product with your pharmacist before starting. Eyebright may increase the risk of low blood sugar.

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.

Eyebright Extract may be worth considering if you're interested in traditional respiratory or eye support, but the evidence for it is still developing. If you take any diabetes medication, you'll need to check with a pharmacist or doctor first — eyebright can lower blood sugar.
