HelloPharmacist Scorecard of Euphrasia Spp. Eyebright by Wise Woman Herbals

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (3 mL) without saying how much of each component you get.

This product contains one active ingredient: eyebright (Euphrasia spp.), a traditional herbal remedy. The liquid also includes alcohol, spring water, and glycerin as inactive 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, Ocular discomfort.
  • 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 isn't established in our data. We hold insufficient reliable evidence to rate it for allergic rhinitis (hay fever), cancer, common cold, cough, pharyngitis, and rhinosinusitis — all the conditions tested in the research we reviewed.

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 in small amounts as a tea, but using homemade or non-sterile preparations directly in the eye carries risk. Safety hasn't been established in pregnancy, so it's best avoided then.

There isn't enough safety information for breastfeeding, so avoid use while nursing. Oral side effects reported in some people include confusion, headache, nausea, constipation, cough, shortness of breath, and nasal congestion.

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 (including insulin), check with your pharmacist before starting this product — eyebright may lower your blood sugar further and raise the risk of low blood sugar reactions.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This product may appeal to people exploring traditional herbal remedies for respiratory or sinus concerns, but the evidence for those uses isn't established in our data. If you take any diabetes medication, talk with your pharmacist or doctor before adding it — blood sugar monitoring may be needed.

Don't use it during pregnancy or while breastfeeding.

How can one product interact with so many drugs?
Euphrasia Spp. Eyebright 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.
Does eyebright actually work for hay fever or sinus problems?
We don't have enough reliable evidence to say. Eyebright has been used traditionally for allergic rhinitis, common cold, cough, and sinus problems, but the data we hold rates all of these as having insufficient evidence.
Can I use this product while I'm pregnant or breastfeeding?
No. Safety hasn't been established in pregnancy, so it's best avoided then. There's not enough safety information for breastfeeding either — talk with your doctor or pharmacist for guidance on what's right for you.

No. Using non-sterile or homemade preparations directly in the eye is risky. This product is designed as a liquid you drink, not an eyewash.
What's in this liquid besides the eyebright?
The inactive ingredients are alcohol, spring water, and glycerin. They're there to extract and preserve the herb and make the product stable.
