HelloPharmacist Scorecard of Coltsfoot Chocolate 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 11, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product has one active ingredient: coltsfoot glycerite liquid extract. The inactive ingredients are glycerin and chocolate flavor.

Does it work?

Couldn't assess
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 assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: respiratory health and cough relief.
  • We looked for evidence on: Cough, Bronchitis, Asthma, Sore throat.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The facts we hold don't include an effectiveness rating for coltsfoot, so the evidence for what it does isn't established in our data.

The evidence, ingredient by ingredient Coltsfoot

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Coltsfoot carries a serious safety flag: it naturally contains liver-toxic compounds called pyrrolizidine alkaloids. The main risks are liver damage (including a condition called veno-occlusive disease with symptoms like belly pain, vomiting, diarrhea, and fluid buildup) and lung damage with high blood pressure in the lungs.

We advise using only certified pyrrolizidine alkaloid–free products, if you use coltsfoot at all. The safety data advises against coltsfoot during pregnancy due to potential liver toxicity and harm to the baby, and while breastfeeding because toxic alkaloids may pass into breast milk.

Why this rating?

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.

Coltsfoot Chocolate Flavor by TerraVita: Common Questions

Does Coltsfoot Chocolate Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Coltsfoot Chocolate Flavor has a known interaction with 374 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Coltsfoot Chocolate Flavor contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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 coltsfoot safe to use during pregnancy?
No. The safety data advises against coltsfoot during pregnancy due to potential liver toxicity and harm to the baby. Do not use it if you're pregnant or planning to become pregnant.
Can I take this while breastfeeding?
No. Toxic alkaloids may pass into breast milk, so the safety data advises against use while breastfeeding.
What's the main safety concern with coltsfoot?
Coltsfoot contains pyrrolizidine alkaloids that can damage your liver and lungs. Liver damage can develop into veno-occlusive disease with symptoms like belly pain, vomiting, diarrhea, and swelling. We recommend using only certified pyrrolizidine alkaloid–free products, if at all.
Does this product interact with blood thinners?
Yes. Coltsfoot slows down platelet aggregation (clotting), so combining it with blood thinners like warfarin, heparin, aspirin, or clopidogrel could increase your bleeding risk. Avoid this combination.
Can coltsfoot affect my blood pressure medication?
Yes. High doses of coltsfoot may interfere with how blood pressure medications work. If you take blood pressure medicine, check with your pharmacist before using this product.
