HelloPharmacist Scorecard of Eyebright Vanilla Flavor by TerraVita

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 glycerite liquid extract — a plant extract traditionally used in herbal medicine, prepared in a glycerin base and flavored with vanilla. The inactive ingredients are glycerin (the liquid base) and vanilla flavoring.

There are no other 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.
  • We looked for evidence on: Asthenopia (eye strain), Conjunctivitis, Allergic rhinitis (hay fever), eye irritation, eye redness.
  • 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 well established yet. Our data shows insufficient reliable evidence to rate it for allergic rhinitis (hay fever), cancer, common cold, cough, pharyngitis, or rhinosinusitis.

That doesn't mean it doesn't work — it means the clinical trials we have so far haven't been rigorous enough to say either way. If you're considering it for one of these conditions, talk with your doctor about what the research currently supports.

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 likely well tolerated, though some people have reported confusion, headache, nausea, constipation, cough, shortness of breath, or nasal congestion. Do not use homemade or non-sterile preparations directly in the eye — the risk of infection and damage is real.

The safety data advises against use during pregnancy and while breastfeeding. If you're pregnant, planning to become pregnant, or nursing, talk with your doctor or pharmacist before taking this product.

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.

Check your antidiabetes medications — insulin, metformin, sulfonylureas, and other blood sugar–lowering drugs — with your doctor or pharmacist before taking this product. Eyebright may lower blood glucose and increase the risk of low blood sugar (a Moderate interaction).

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Eyebright Vanilla Flavor may appeal to someone interested in herbal approaches to respiratory or allergic symptoms, though the evidence for it isn't established in the data we hold. The main caution is if you take diabetes medications — the risk of low blood sugar is real and worth discussing with your own doctor or pharmacist first.
