HelloPharmacist Scorecard of Eyebright Extract by Christopher's Original Formulas

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: organic eyebright, an herbal extract in liquid form. It's prepared with a base of other inactive ingredients that serve as the carrier for the extract.

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's effectiveness is insufficient in the data we hold. It's been studied for allergic rhinitis (hay fever), common cold, cough, pharyngitis, rhinosinusitis, and cancer — but none of these uses have reliable evidence to support a rating.

That doesn't mean it doesn't work; it means the research available doesn't yet establish that 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.

Taken by mouth in small amounts, eyebright is generally well tolerated, though some people report confusion, headache, nausea, constipation, cough, shortness of breath, or nasal congestion. The safety data advises against use during pregnancy and while breastfeeding — there isn't enough information to know it's safe in either situation.

One important caution: using homemade or non-sterile preparations directly in the eye carries a real risk of harm, so eyebright for eye health should not be used as an eye drop unless it's been specially prepared and sterilized for that purpose.

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 drug or medication that lowers blood sugar, check your specific medication on this page before using this product, and confirm with your doctor or pharmacist that it's safe to combine.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Eyebright Extract might interest someone looking for a traditional herbal approach to eye or respiratory health, but the evidence to support its effectiveness isn't established yet. If you take any diabetes or blood-sugar medication, you'll want to clear this with your doctor or pharmacist first.

Pregnancy and breastfeeding are times to avoid it. Talk it over with your own healthcare provider before you start.

Eyebright Extract by Christopher's Original Formulas: Common Questions

Does Eyebright Extract by Christopher's Original Formulas interact with any medications?
Yes. Based on its ingredients, Eyebright Extract 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 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 while I'm pregnant or breastfeeding?
The safety data advises against eyebright during pregnancy and while breastfeeding — there isn't enough information to know it's safe in either situation. Talk with your doctor or pharmacist about whether it's right for you before you use it.
What side effects might I experience if I take this?
Some people report confusion, headache, nausea, and constipation. Others have reported cough, shortness of breath, or nasal congestion. If you notice any of these, stop and let your doctor or pharmacist know.
Does eyebright actually work for hay fever or other conditions?
The evidence in our data is insufficient to rate eyebright's effectiveness for allergic rhinitis, common cold, cough, and other uses. That means the research available doesn't yet establish that it works for these purposes.
Can I put this liquid directly in my eyes?
No — the safety data cautions against using homemade or non-sterile preparations directly in the eye because of the risk of harm. If you want to use eyebright for eye health, it needs to be specially prepared and sterilized for that purpose.
I take insulin. Is this product safe for me?
Eyebright may lower blood sugar on its own, so combining it with insulin could theoretically increase the risk of low blood sugar. Check your specific medication on this page, and talk with your doctor or pharmacist before you start.
