HelloPharmacist Scorecard of Bronchitis Formula 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

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 7 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 seven active ingredients: agrimony glycerite, coltsfoot glycerite, mallow glycerite, mullein flower glycerite, poppy seed glycerite, tarrify herb glycerite, and English ivy glycerite. They're delivered in a base of glycerin, which serves as both a preservative and a carrier for the herbal extracts.

The formula is designed as a blend, so the relative amounts of each ingredient aren't itemized on the label.

Does it work?

Insufficient evidence
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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Support respiratory health and cough relief.
  • We looked for evidence on: Asthma, Bronchitis, Cough, Respiratory tract infections, Chest congestion, Mucus clearance.
  • The closest evidence on file: Mallow is rated "Insufficient Reliable Evidence To Rate" for Cough (Natural Medicines).
  • Also on file: English Ivy is rated "Insufficient Reliable Evidence To Rate" for Bronchitis, Respiratory tract infections, Cough.
  • Also on file: Mullein is rated "Insufficient Reliable Evidence To Rate" for Bronchitis, Asthma, Cough.

The evidence for this formula's ingredients is sparse. Mullein flower, agrimony, and English ivy all lack reliable evidence for bronchitis, cough, or respiratory conditions.

Mallow also shows insufficient evidence for cough. Poppy seed is rated likely effective for a diagnostic imaging procedure (vesicoenteric fistula diagnosis) but shows insufficient evidence for cough or insomnia.

In short, we don't have solid data showing any of these ingredients work for the conditions this product targets.

The evidence, ingredient by ingredient Agrimony Coltsfoot Mallow Mullein Poppy Seed 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 5 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Coltsfoot is the biggest safety red flag here. It contains liver-toxic alkaloids (pyrrolizidine alkaloids) that can damage your liver and lungs with chronic use, potentially causing vein blockage in the liver, fluid buildup in the belly, and vomiting.

The product should only be used if it's certified free of these alkaloids. Mullein flower and mallow are generally well tolerated short-term, though human safety data are limited.

Poppy seed in normal food amounts is safe, but large medicinal doses may contain trace opiates and could trigger a drug test or cause serious breathing problems in rare cases. English ivy extracts are generally well tolerated, but the raw plant is toxic.

All of these ingredients lack adequate safety data in pregnancy and breastfeeding, so they should be avoided during those times unless your doctor clears them.

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?
  • 4 of the 6 matched ingredients can interact with medications — English Ivy, Mullein, Agrimony, Coltsfoot.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 678 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 blood thinners (anticoagulants or antiplatelets like warfarin or aspirin), diabetes drugs, blood pressure medications, or drugs that speed up liver metabolism like phenytoin. Also check if you're on medications processed by your liver through CYP2C19, CYP2D6, or CYP2C8 enzymes — English ivy may raise their levels.

The medication checker below is your best tool.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This is a multi-herb formula with documented interactions affecting hundreds of medications, especially blood thinners, diabetes drugs, and several liver-processed medications. Coltsfoot carries a real risk of liver and lung damage.

If you take any prescription medications—particularly blood thinners, diabetes meds, or blood pressure drugs—check each one with the tool on this page before trying this product. Talk to your pharmacist or doctor first, especially if you're pregnant, breastfeeding, or have liver disease.

Coltsfoot Glycerite Liquid Extract3 drug types · 374 drugs

Anticoagulant/Antiplatelet Drugs

Concomitant use might increase the risk of bleeding due to decreased platelet aggregation. Coltsfoot has been reported to inhibit platelet aggregation; avoid concomitant use. Some of these drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, excessive doses of coltsfoot may interfere with antihypertensive or cardiovascular therapy.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Inducers

Hepatotoxic pyrrolizidine alkaloids (PA) are substrates of cytochrome P450 3A4 (CYP3A4). Theoretically, drugs that induce CYP3A4 might increase the conversion of PAs to toxic metabolites. Some drugs that induce CYP3A4 include carbamazepine (Tegretol), phenobarbital, phenytoin (Dilantin), rifampin, rifabutin (Mycobutin), and others.

Likelihood Possible Evidence D

Common Ivy Glycerite Liquid Extract3 drug types · 280 drugs

Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, English ivy might increase the levels of drugs metabolized by CYP2C19.
In vitro research shows that English ivy inhibits CYP2C19 enzymes. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C8 (Cyp2C8) Substrates

Theoretically, English ivy might increase the levels of drugs metabolized by CYP2C8.
In vitro research shows that English ivy inhibits CYP2C8 enzymes. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, English ivy might increase the levels of drugs metabolized by CYP2D6.
In vitro research shows that English ivy inhibits CYP2D6 enzymes. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D

Mullein Flower Glycerite Liquid Extract 1 drug type · 122 drugs

Anticoagulant/Antiplatelet Drugs

Lab tests on extracts from different parts of common and dense-flowered mullein plants show that they do have some blood-thinning effects, as they increase the time it takes for blood to clot. This is likely due to at least one of the known constituents of muellein, triterpenoid saponins. However, the effects appear to be mild and results have been inconsistent. Extracts from different plant parts have been show to have varying anticoagulant strengths, with water-based ones being more potent than alcohol-based extracts.

Likelihood Unlikely Evidence A

Agrimony Glycerite Liquid Extract1 drug type · 86 drugs

Antidiabetes Drugs

Theoretically, taking agrimony with antidiabetes drugs might increase the risk of hypoglycemia.
Agrimony has demonstrated hypoglycemic effects in animal research.

Bronchitis Formula by TerraVita: Common Questions

Does Bronchitis Formula by TerraVita interact with any medications?
Yes. Based on its ingredients, Bronchitis Formula has a known interaction with 677 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Bronchitis Formula contains 7 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 during pregnancy?
No. Coltsfoot is rated likely unsafe in pregnancy and poses a risk of liver damage to the baby. Agrimony, mullein, and English ivy lack enough safety data and are best avoided. Only poppy seed is rated likely safe, but since the formula contains multiple ingredients with safety warnings, you should avoid this product during pregnancy unless your doctor specifically clears it.
Can I breastfeed while taking this?
The safety data don't support it. Coltsfoot is likely unsafe — its toxic alkaloids may pass into breast milk. Agrimony, mullein, and English ivy all have insufficient breastfeeding data. Poppy seed in small amounts is likely safe, but the product as a whole is best avoided unless your doctor approves.
Does this actually help with bronchitis or cough?
We don't have reliable evidence that it does. Mullein flower, agrimony, mallow, and English ivy all show insufficient evidence for bronchitis or cough. Poppy seed isn't rated for cough either. The ingredients are traditional folk remedies, but that's not the same as proven to work.
What's coltsfoot, and why is it risky?
Coltsfoot is a plant used in herbal medicine, but it naturally contains liver-toxic alkaloids. Chronic use can damage your liver and lungs, causing vein blockage, fluid buildup, and nausea. The product should be certified free of these alkaloids, and it's best avoided unless your doctor says it's okay.
Will this affect my blood pressure or diabetes medication?
Possibly. Coltsfoot may interfere with blood pressure drugs, and agrimony may lower blood sugar too much if you're already on diabetes medication — raising your risk of low blood sugar. That's why you need to check your exact medications with the tool on this page before starting.
Why does the product say it may trigger a drug test?
Poppy seed, even in food amounts, can contain trace amounts of opiates. Large medicinal doses carry a higher risk of affecting a drug screening test. If you're subject to drug testing, this is worth discussing with your doctor or pharmacist first.
