HelloPharmacist Scorecard of Bronchial Clear 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 Complex (Herb/Botanical)” is a proprietary blend — the label gives one combined amount (250 mg) without saying how much of each component you get.

Bronchial Clear has 2 active ingredients. Thyme leaf extract is the first, a traditional remedy for respiratory support.

The second is climbing ivy (English ivy) leaf extract, also used traditionally for respiratory tract comfort. Both are provided as concentrated extracts in tablet form.

The product also contains several inactive ingredients — cellulose, calcium carbonate, and a few binders and coatings — to hold the tablet together and make it easy to swallow.

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 on how well either ingredient works for bronchitis, colds, or other respiratory issues isn't established in the data we hold. Both thyme and English ivy have a long history in traditional medicine, but the clinical research to show they're effective for any of these purposes isn't strong enough to rate.

If you're considering this for a specific condition, that's worth discussing with your doctor or pharmacist.

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 leaf extract in medicinal amounts is generally well tolerated, though a small number of people report allergic reactions, diarrhea, dizziness, headache, heartburn, nausea, or vomiting when taken by mouth. Topically, it can sometimes cause contact dermatitis.

The concentrated essential oil form of thyme can be toxic if swallowed, but this product is an extract, not the pure oil. English ivy leaf extract also seems well tolerated orally, with the most common side effects being abdominal pain, diarrhea, nausea, and vomiting in a small number of users.

Topically, it can cause contact dermatitis or allergic reactions. Thyme is rated likely safe in pregnancy and lactation.

English ivy, however, does not have enough safety data — the facts advise against it during pregnancy and note that safety while breastfeeding is unknown, so talk with your doctor or pharmacist before using if you're pregnant or nursing.

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.

Check your medications if you take estrogens or hormone replacement therapy, blood thinners or antiplatelet drugs (like warfarin or aspirin), or anticholinergic or cholinergic medications. Also flag any drugs metabolized by your liver's CYP2C19, CYP2D6, or CYP2C8 enzymes — if you're not sure, ask your pharmacist to run your exact medication list through the interaction checker on this page.

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.

Bronchial Clear is an herbal combination that's generally well tolerated, but if you take any medications — especially blood thinners, hormone therapy, or drugs for bladder or nerve issues — check your specific medications on this page first. The interactions documented here are lab-based and unconfirmed in people, but they're worth clarifying before you start.

Bronchial Clear by Terry Naturally: Common Questions

Does Bronchial Clear by Terry Naturally interact with any medications?
Yes. Based on its ingredients, Bronchial Clear 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 contains 2 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 it safe to take this if I'm pregnant or breastfeeding?
Thyme in this product is rated likely safe during pregnancy and lactation. English ivy, however, doesn't have enough safety data — the research advises against it during pregnancy and notes the safety while breastfeeding is unknown. Talk with your doctor or pharmacist before starting this product if you're pregnant or nursing.
What are the most common side effects?
Thyme can cause dizziness, headache, nausea, vomiting, diarrhea, or heartburn in a small number of people. English ivy may cause abdominal pain, diarrhea, nausea, or vomiting. Topically, both can cause contact dermatitis, though this product is taken by mouth.
Why does the interaction list mention so many medications?
English ivy can theoretically inhibit enzymes in your liver that break down many different drugs — over 580 medications use those enzymes. The risk is real but hasn't been seen in humans yet, so it's worth checking your specific list before starting.
Does this work for bronchitis or a cold?
The evidence isn't strong enough to say. Both thyme and English ivy have a long history in traditional medicine for respiratory support, but reliable clinical studies showing they work for bronchitis or colds haven't been established in the data we hold.
What's the difference between the thyme in this and thyme essential oil?
This product contains thyme leaf extract, which is well tolerated. Thyme essential oil, the concentrated form, can be toxic if swallowed, so you shouldn't take that. The extract is much safer at the doses used here.
Is English ivy safe, given all those side effects listed?
English ivy leaf extract seems to be well tolerated — most people don't report side effects. When they do occur, they're typically mild digestive issues or skin irritation. Just avoid the raw plant, which can be toxic.
