HelloPharmacist Scorecard of Eyebright by L.A. Naturals

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

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.

This product contains one active ingredient: ethically wild harvested eyebright, a plant used traditionally to support eye and respiratory health. The liquid also contains grain alcohol and deionized water as inactive ingredients to preserve and deliver the eyebright extract.

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 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 isn't established in the data we hold. The facts list six uses — hay fever, cancer, common cold, cough, sore throat, and sinus problems — and for all of them, the rating is the same: insufficient reliable evidence to rate.

That means we don't have strong clinical trial data to say whether it works for any of these purposes. If you're considering it for a specific concern, talk it over with your doctor or pharmacist about what evidence exists outside our data.

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.

Orally, eyebright is generally well tolerated in small amounts as a tea, but a small number of people report confusion, headache, nausea, constipation, cough, shortness of breath, and nasal congestion. One important caution: using homemade or non-sterile eyebright preparations directly in the eye carries a real risk of injury and infection — stick to oral forms from reputable makers.

The safety data advises against using eyebright during pregnancy and while breastfeeding, so if you're pregnant, nursing, or planning to be, talk with your doctor or pharmacist before taking it.

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 drug to lower your blood sugar, check with your doctor or pharmacist before adding this product — eyebright may enhance that effect and drop your blood sugar too low.

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.

Eyebright is a traditional herbal extract with no strong evidence yet that it works for the conditions it's marketed for. If you take diabetes medication, check your blood sugar numbers carefully or clear it with your pharmacist first — it may lower your glucose further.

If you're pregnant, nursing, or have other health concerns, talk it over with your doctor or pharmacist before starting.

Eyebright by L.A. Naturals: Common Questions

Does Eyebright by L.A. Naturals interact with any medications?
Yes. Based on its ingredients, Eyebright 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 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 dry eyes or eye irritation?
The effectiveness data we hold shows insufficient evidence to rate eyebright for eye conditions. The facts also warn against putting homemade or non-sterile eyebright directly in the eye because of infection risk, so stick to oral forms. Talk with your eye doctor about what's proven to work for your specific eye concern.
What side effects might I get from taking eyebright?
Orally, a small number of people report confusion, headache, nausea, constipation, cough, shortness of breath, and nasal congestion. Most people seem to tolerate small amounts as a tea without trouble, but watch for any of these if you're new to it.
Is eyebright safe to take while pregnant or breastfeeding?
No — the safety data advises against both. If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist before taking eyebright.
I take metformin for diabetes. Can I use this product?
Eyebright may lower blood sugar itself, so combining it with your diabetes medication could drop your glucose too low. Check with your doctor or pharmacist first — they can watch your numbers and adjust your dose if needed.
Does this product actually work for hay fever or colds?
The evidence isn't strong enough yet to say. For hay fever, colds, cough, sore throat, and sinus problems, the data shows insufficient reliable evidence to rate whether eyebright helps. If you're considering it for one of these, ask your doctor or pharmacist whether there's newer evidence or a better-proven option.
