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

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 is a single-ingredient supplement: eyebright aerial part extract, 500 mg per serving. Eyebright is an herb traditionally used for eye health and respiratory symptoms.

The product contains no other active ingredients and no inactive fillers or binders listed.

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 support.
  • We looked for evidence on: Asthenopia (eye strain), Conjunctivitis, Allergic rhinitis (hay fever), eye irritation, eye redness, ocular comfort.
  • 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 doesn't support any reliable benefit yet. Our data shows insufficient reliable evidence to rate it for allergic rhinitis (hay fever), common cold, cough, sore throat (pharyngitis), sinus inflammation (rhinosinusitis), or cancer.

In other words, we don't have solid trial data backing these uses — that doesn't mean it doesn't work, but it does mean we can't confirm it does.

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 generally well tolerated in small amounts as a tea, but direct application to the eye — especially with homemade or non-sterile preparations — carries risk and isn't advised. Orally, some people report confusion, headache, nausea, constipation, cough, shortness of breath, and nasal congestion, though these aren't common in trial data.

Safety hasn't been established in pregnancy, so the data advises against use. There isn't enough safety information for breastfeeding — talk with your doctor or pharmacist about whether it's right for you.

Known Interaction Concern · database check

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?

  • 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.

Check your diabetes medications before taking this product. Eyebright may increase the risk of low blood sugar (a Moderate-severity interaction) with insulin, metformin, and other antidiabetes drugs.

Eyebright Extract Powder 500 mg by BulkSupplements.com: Common Questions

Does Eyebright Extract Powder 500 mg by BulkSupplements.com interact with any medications?
Yes. Based on its ingredients, Eyebright Extract Powder 500 mg 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 Extract Powder 500 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.
What is eyebright and what's it used for?
Eyebright is an herb — the aerial parts (leaves, stems, flowers) are extracted and dried into powder. It's traditionally used for eye health and symptoms like cough and sore throat, though our data shows the evidence isn't strong enough yet to confirm those benefits.
Can I use eyebright if I take diabetes medication?
You need to check with your pharmacist first. Animal research suggests eyebright lowers blood glucose, so taking it with diabetes drugs could increase your risk of low blood sugar (hypoglycemia) — a Moderate-severity interaction. Your pharmacist can help you decide whether it's safe for your situation and whether you need closer blood sugar monitoring.
Is it safe to put this powder directly in my eye?
No, we don't recommend it. The safety data warns against using eyebright directly in the eye, especially homemade or non-sterile preparations, because of infection and irritation risk. Stick to taking it by mouth as directed.
What side effects might I experience?
Oral use has been reported to cause confusion, headache, nausea, constipation, cough, shortness of breath, and nasal congestion in some people — though these aren't common. Stop and call your pharmacist if you notice any unusual symptoms.
Is it safe during pregnancy or breastfeeding?
The safety data advises against eyebright in pregnancy because it hasn't been studied enough. If you're breastfeeding, there also isn't enough safety information — talk with your doctor or pharmacist about whether it's right for you before starting.
Does eyebright actually work for allergies or a cold?
Our data shows insufficient reliable evidence to rate it for hay fever, common cold, cough, sore throat, or sinus issues. That means we don't have solid trial data backing those claims yet — not that it definitely doesn't work, but we can't confirm it does.
