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 ingredients: thyme leaf extract and ivy leaf extract, both in liquid form. Thyme is traditionally used for respiratory support, while ivy is included for similar purposes.

The product also contains inactive ingredients—purified water, sorbitol, glycerol, potassium sorbate, xanthan gum, and citric acid—that serve as the liquid base and preservatives.

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: Support healthy lung and 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 on both thyme and ivy for bronchitis, respiratory infections, and related uses is insufficient in the data we hold. That doesn't mean they don't work—it means reliable clinical studies backing them for these specific purposes aren't yet established in our files.

If you're considering this product for a respiratory condition, talk with your pharmacist or doctor about what evidence does exist and whether it might help you.

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 as a food or in medicinal doses, though the concentrated essential oil can be toxic if swallowed—this product is a liquid extract, so follow the label dosing carefully. The most common side effects with oral thyme are allergic reactions, diarrhea, dizziness, headache, heartburn, nausea, or vomiting.

Topically, it may cause contact dermatitis or skin irritation. Ivy leaf extract in standardized form (like this product) is generally well tolerated orally, with the main side effects being abdominal pain, diarrhea, nausea, vomiting, and skin irritation.

Raw ivy is toxic, so stick to extracts only. During pregnancy, safety data for ivy is insufficient—the facts advise against use.

During breastfeeding, safety is unknown, so avoid unless your doctor approves. Thyme is rated likely safe in pregnancy and lactation.

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 you start Bronchial Clear Liquid, check with your pharmacist if you take any drugs processed by the liver enzymes CYP2C19, CYP2D6, or CYP2C8—that covers a broad range of medications. Also double-check if you're on estrogen replacement therapy, blood thinners (anticoagulants or antiplatelet drugs), or anticholinergic or cholinergic medications.

Use the search tool on this page to confirm your exact medications are safe to combine with this product.

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 may be worth a try if you're looking for respiratory support, but the interaction profile is substantial because of ivy's effects on liver enzymes. If you take any prescription medications—especially those for heart rhythm, depression, pain, or any chronic condition—check them against the drug interaction tool on this page first.

Talk to your pharmacist before starting, and definitely avoid this product if you're pregnant and concerned about ivy.

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.
Does this product have anything in it besides the active ingredients?
Yes. The liquid base and preservatives include purified water, sorbitol, glycerol, potassium sorbate, xanthan gum, and citric acid. These are inactive ingredients that help preserve and deliver the thyme and ivy extracts.
Can I take this if I'm pregnant or breastfeeding?
Thyme is rated likely safe in pregnancy and lactation. Ivy is a different story: there's not enough safety data in pregnancy, so it's advised against, and safety while breastfeeding is unknown. Talk with your doctor before using this product if you're pregnant or nursing.
What side effects might I notice from this product?
Thyme commonly causes dizziness, headache, heartburn, nausea, diarrhea, or vomiting. Ivy can cause abdominal pain, diarrhea, nausea, and vomiting. Both may trigger allergic reactions or skin irritation in some people. If you notice any of these, stop and let your pharmacist know.
Will this actually help my cough or bronchitis?
The evidence backing thyme and ivy for bronchitis and respiratory infections isn't established in our data—it's rated insufficient. That doesn't mean it won't help you, but there aren't solid clinical studies we can point to yet. Your doctor or pharmacist can tell you more about what people report.
Is this safe with my blood thinner?
Thyme might theoretically add to the blood-thinning effects of anticoagulant or antiplatelet drugs—but this hasn't been seen in real patients. Still, you should absolutely check this with your pharmacist before starting, especially if you're on warfarin or similar medications.
How does a supplement with only two ingredients interact with 582 medications?
The ivy in this product slows how your liver breaks down drugs processed by three major enzyme systems. Because so many different medications rely on those same enzymes, a single ingredient can theoretically affect a huge range of drugs. That's why it's crucial you check your exact medications.
