HelloPharmacist Scorecard of Eyebright Herb 430 mg by Swanson Premium Brand

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 at 430 mg per capsule. Eyebright has been used traditionally to support eye health and respiratory function, though the evidence for most of those uses remains limited.

The capsule also contains inactive ingredients — gelatin, microcrystalline cellulose, medium-chain triglycerides oil, magnesium stearate, and silica — which serve as the capsule shell and to keep the powder flowing and stable.

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 insufficient for us to rate it reliably across the conditions it's commonly used for — allergic rhinitis (hay fever), cough, common cold, pharyngitis, and rhinosinusitis among them. We also don't have established evidence for its use against cancer.

If you're considering it for a specific symptom or condition, it's worth discussing what the research actually shows with your doctor or pharmacist.

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 the data advises against using homemade or non-sterile preparations directly in the eye — that carries real risk of contamination or irritation. The safety data advises against taking eyebright during pregnancy and while breastfeeding, since we don't have enough information to know it's safe in those circumstances.

Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant, planning pregnancy, or nursing. Orally, eyebright has been reported to cause confusion, headache, nausea, constipation, cough, shortness of breath, and nasal congestion in some people.

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, sulfonylureas, or others — check with your doctor or pharmacist before adding eyebright, since it may lower blood sugar further and raise the risk of hypoglycemia (Moderate interaction). We could not check eyebright against other medications in our database.

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 appeal to someone looking for traditional respiratory or eye support, but the evidence for most claimed uses is limited. If you take diabetes medications, you'll need to check with your doctor first because eyebright may lower blood sugar.

Pregnant people and those breastfeeding should avoid it. Talk it over with your own doctor or pharmacist before starting.

Eyebright Herb 430 mg by Swanson Premium Brand: Common Questions

Does Eyebright Herb 430 mg by Swanson Premium Brand interact with any medications?
Yes. Based on its ingredients, Eyebright Herb 430 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 Herb 430 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.
Can I use eyebright for allergies or a cold?
Eyebright is used traditionally for those, but we don't have reliable evidence that it actually works for allergic rhinitis, cough, colds, or sore throat. If you're interested in it for one of those reasons, talk with your doctor about whether the evidence supports it and whether it's right for you.
Is eyebright safe to put directly in my eye?
The safety data advises against using homemade or non-sterile preparations in the eye — that's too risky for contamination and irritation. This product is a capsule you swallow by mouth, not an eye drop.
What side effects might I notice?
Eyebright has been reported to cause confusion, headache, nausea, constipation, cough, shortness of breath, and nasal congestion when taken by mouth. If you experience any of these, stop taking it and talk with your pharmacist or doctor.
Is it safe during pregnancy or while breastfeeding?
No — the safety data advises against eyebright during pregnancy and while breastfeeding because we don't have enough information to know it's safe. Talk with your doctor or pharmacist about your options if you're pregnant, planning pregnancy, or nursing.
I take a diabetes medication. Can I take this?
Animal research suggests eyebright lowers blood glucose, so it may add to the blood-sugar-lowering effect of your medication and raise your risk of low blood sugar. Check with your own doctor or pharmacist before starting this product.
