HelloPharmacist Scorecard of Chest Congestion Formula Strawberry 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 12, 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 3 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (0.13 mL) without saying how much of each component you get.

This liquid formula contains 3 active ingredients in a proprietary blend: hyssop glycerite liquid extract, eucalyptus glycerite liquid extract, and eyebright glycerite liquid extract. Each is a plant extract in glycerin, a common herbal preparation form.

The product also contains glycerin and strawberry flavor 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.

Why this rating?
  • The label markets this product for: chest congestion and cough relief.
  • We looked for evidence on: Asthma, Bronchitis, Common cold, Cough, Influenza, Pharyngitis — and 4 related terms.
  • The closest evidence on file: Eyebright is rated "Insufficient Reliable Evidence To Rate" for Common cold (Natural Medicines).
  • Also on file: Eyebright is rated "Insufficient Reliable Evidence To Rate" for Cough, Pharyngitis, Rhinosinusitis.
  • Also on file: Hyssop is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections, Cough, Sore throat.

The evidence supporting these ingredients for chest congestion or respiratory complaints isn't established in our data. Hyssop, eucalyptus, and eyebright all carry ratings of insufficient reliable evidence for cough, respiratory tract infections, sore throat, allergic rhinitis, and common cold.

That doesn't mean they don't work—it means the scientific evidence to rate them isn't available to us.

The evidence, ingredient by ingredient Hyssop Eucalyptus 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 2 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Eucalyptus is generally well tolerated in diluted form, though the undiluted oil can be toxic if swallowed and may cause diarrhea, nausea, or vomiting. Hyssop is thought to be low-risk in small amounts, but the concentrated essential oil can trigger seizures.

Eyebright is likely safe as a tea in small amounts. Because this is a liquid glycerite (not pure essential oil), toxicity risk is lower than with undiluted products, but check with your pharmacist if you have seizure concerns or take seizure medications.

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?
  • 2 of the 3 matched ingredients can interact with medications — Eyebright, Eucalyptus.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 879 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.

Before starting, check the drug-interaction tool on this page if you take diabetes medications (especially those that lower blood sugar), any amphetamines, pentobarbital, or medications processed through your liver's cytochrome P450 system (CYP1A2, CYP2C19, CYP2C9, or CYP3A4). These are all Moderate-severity concerns.

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.

If you're using this for chest congestion, talk to your pharmacist first—especially if you take diabetes medications, amphetamines, pentobarbital, or drugs processed by your liver (a long list). The evidence for whether it works isn't established, and the ingredient interactions are significant enough to warrant a quick medication check before you start.

Chest Congestion Formula Strawberry Flavor by TerraVita: Common Questions

Does Chest Congestion Formula Strawberry Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Chest Congestion Formula Strawberry Flavor has a known interaction with 880 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Chest Congestion Formula Strawberry Flavor contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Is this safe to take while I'm pregnant or breastfeeding?
Hyssop is rated likely unsafe in pregnancy because it's traditionally thought to stimulate the uterus. Eyebright also hasn't been studied enough and should be avoided during pregnancy and breastfeeding. Eucalyptus is rated likely safe, but because this is a blend and pregnancy safety data isn't complete for all three, talk to your doctor or pharmacist about your specific situation before you start.
Does this actually work for congestion?
The science we have on these ingredients for congestion, cough, and respiratory infections is insufficient to rate them one way or the other. That doesn't mean they don't help—it means we don't have reliable evidence either way yet.
What's a glycerite, and why is it used here?
A glycerite is a plant extract made by steeping the herb in glycerin instead of alcohol or water. It's a gentler, sweeter-tasting way to deliver herbal ingredients, which is why it's popular in children's and flavored formulas like this one.
Can eucalyptus cause seizures?
The undiluted essential oil has been linked to seizures in some people, especially at high doses or when inhaled or applied topically in large amounts. This product is a diluted glycerite, so the risk is much lower, but if you have a seizure disorder or take seizure medications, ask your pharmacist before using it.
What side effects does this have?
Eucalyptus may cause diarrhea, nausea, or vomiting if taken orally in large amounts. Eyebright has been reported to cause confusion, headache, nausea, constipation, or cough. Hyssop adverse effects aren't documented in our data. Since this is a liquid blend in small doses, side effects are likely to be mild or rare.
