HelloPharmacist Scorecard of Bronchial Clear Liquid by Terry Naturally

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 2 active ingredients.
  • “Proprietary Formula” is a proprietary blend — the label gives one combined amount (880 mg) without saying how much of each component you get.

Bronchial Clear Liquid contains two active herbal ingredients: thyme aerial liquid extract and English ivy leaf liquid extract. These are combined in a proprietary blend formulation, plus several inactive ingredients (water, sorbitol, glycerol, potassium sorbate, xanthan gum, and citric acid) that serve as preservatives, thickeners, and flavor modifiers.

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: Supports healthy lung and upper respiratory function.
  • We looked for evidence on: Bronchitis, Common cold, Cough, Laryngitis, Respiratory tract infections, Tonsillitis — and 4 related terms.
  • The closest evidence on file: English Ivy is rated "Insufficient Reliable Evidence To Rate" for Bronchitis (Natural Medicines).
  • Also on file: English Ivy is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections, Cough.
  • Also on file: Thyme is rated "Insufficient Reliable Evidence To Rate" for Bronchitis, Common cold, Cough, Tonsillitis.

The evidence for what this product can do isn't established in the data we hold. Both thyme and English ivy are listed with insufficient reliable evidence to rate them for the conditions they're traditionally used for—bronchitis, respiratory tract infections, and common cold among them.

That doesn't mean they don't work; it means the research backing their use is limited or mixed.

The evidence, ingredient by ingredient Thyme English Ivy

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

Thyme is generally well tolerated when used in food and medicinally, though the concentrated essential oil can be toxic if swallowed—this liquid extract isn't the essential oil, but higher doses should be approved by your doctor first. English ivy leaf extract in standardized form is generally well tolerated, but the raw plant is toxic.

The most common side effects from thyme orally are allergic reactions, diarrhea, dizziness, headache, heartburn, nausea, or vomiting; topically it can cause contact dermatitis. English ivy orally may cause abdominal pain, diarrhea, nausea, or vomiting; topically it can trigger allergic reactions or contact dermatitis.

For pregnancy, thyme is rated likely safe. English ivy, however, should not be used in pregnancy due to insufficient safety data, and breastfeeding safety is unknown—talk with your doctor or pharmacist before taking it if you're nursing.

Side effects, ingredient by ingredient Thyme English Ivy

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 2 matched ingredients can interact with medications — English Ivy, Thyme.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 586 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 taking this product, check any medications that are metabolized by your liver's CYP2C19, CYP2D6, or CYP2C8 pathways (English ivy can theoretically raise their levels). Also double-check if you take estrogen replacement therapy, anticoagulants or antiplatelet drugs like warfarin or aspirin, anticholinergic medications, or cholinergic drugs—thyme may theoretically interact with all of these.

No interactions are documented in humans for any of these, but the theoretical risk warrants a conversation with your pharmacist.

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 is aimed at respiratory support, but we don't have solid evidence it works for that purpose. The main concern is the broad potential for English ivy to raise blood levels of certain medications, plus thyme's theoretical effects on blood thinners and hormone therapy.

If you take any prescription medications—especially blood thinners, estrogen, or drugs metabolized by the liver—check them here first. Talk to your pharmacist before starting.

Bronchial Clear Liquid by Terry Naturally: Common Questions

Does Bronchial Clear Liquid by Terry Naturally interact with any medications?
Yes. Based on its ingredients, Bronchial Clear Liquid has a known interaction with 586 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Bronchial Clear Liquid 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 if I'm pregnant?
Thyme is rated likely safe in pregnancy. English ivy, however, should be avoided—there isn't enough safety data to know it's okay. Talk with your doctor or pharmacist before using this product if you're pregnant.
Can I take this while breastfeeding?
Thyme is rated likely safe in pregnancy and likely safe generally, so it's probably okay for breastfeeding too, but data is limited. English ivy safety during breastfeeding is unknown, so you should avoid it unless your doctor approves. Check with your pharmacist.
What side effects should I watch for?
The most common ones are digestive—nausea, diarrhea, vomiting, or abdominal pain. You might also experience dizziness, headache, heartburn, or allergic reactions. If you use it topically, watch for contact dermatitis or skin irritation.
Does this product actually work for bronchitis or colds?
The evidence isn't established in our data. Both thyme and English ivy are rated with insufficient reliable evidence for bronchitis, respiratory infections, and common cold. That doesn't mean they can't help, just that the research behind them is limited.
Is the essential oil the same as this liquid extract?
No. Thyme's concentrated essential oil can be toxic if swallowed; this is a liquid extract, which is different. That said, medicinal doses of thyme extract should still be approved by your doctor first.
