HelloPharmacist Scorecard of Coltsfoot & Wormwood Mint 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

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.
  • “Coltsfoot & Wormwood Glycerite Liquid Extract” is listed as a grouped ingredient — the label gives one combined amount (0.13 mL) without saying how much of each component you get.

This product contains two active ingredients as a liquid glycerite extract: coltsfoot and wormwood (also known as Sweet Annie). The inactive ingredients are glycerin and mint flavor.

Glycerin is the base that preserves and delivers the plant extracts; mint flavoring is added for taste.

Does it work?

Moderate 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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Allergic rhinitis (hay fever) — rated "Possibly Effective" (Sweet Annie) (Natural Medicines).

Wormwood shows possibly effective evidence for allergic rhinitis (hay fever), but the data we hold doesn't establish how well it works for other conditions — nonalcoholic fatty liver disease, malaria, and osteoarthritis all have insufficient reliable evidence. We have no effectiveness ratings on file for coltsfoot.

The evidence, ingredient by ingredient Coltsfoot Sweet Annie

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.

Coltsfoot's main safety concern is its pyrrolizidine alkaloid content, which can damage the liver and lungs with chronic use. The product safety notes caution using only certified PA-free products, if at all.

Wormwood is generally well tolerated at short-term doses, though nausea and vomiting can occur; rarely, it may cause liver damage, and one case of allergic reaction (rash and cough) has been reported. Both ingredients carry strong warnings: avoid coltsfoot entirely during pregnancy (rated Likely Unsafe) and while breastfeeding because toxic alkaloids pass into breast milk.

Avoid wormwood during pregnancy due to possible harm to the baby, and there isn't enough safety information to recommend it while breastfeeding.

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 — Coltsfoot, Sweet Annie.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 1,122 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 with your pharmacist if you take blood thinners or antiplatelet drugs like warfarin, aspirin, or clopidogrel (Plavix); blood pressure medications; seizure drugs like carbamazepine (Tegretol), phenytoin (Dilantin), or phenobarbital; tuberculosis drugs like rifampin; or any drug metabolized by the liver. Moderate-severity interactions are documented across all these categories.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This product carries serious safety and interaction concerns and is not a routine choice. If you're considering it for hay fever, talk with your pharmacist first — especially if you take any blood thinners, blood pressure medications, seizure drugs, or liver-damaging medicines.

Pregnant women and nursing mothers should avoid it entirely.

Coltsfoot & Wormwood 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 & Wormwood Mint Flavor by TerraVita: Common Questions

Does Coltsfoot & Wormwood Mint Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Coltsfoot & Wormwood Mint Flavor has a known interaction with 1,121 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Coltsfoot & Wormwood Mint 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.
Can I take this while I'm pregnant or breastfeeding?
No. Coltsfoot is rated Likely Unsafe in pregnancy because of potential liver toxicity and harm to the baby, and it should not be used while breastfeeding because toxic alkaloids pass into breast milk. Wormwood should also be avoided in pregnancy and while breastfeeding due to insufficient safety data. Talk with your doctor or pharmacist about safer alternatives.
What is pyrrolizidine alkaloid (PA) and why does it matter?
Pyrrolizidine alkaloids are natural compounds in coltsfoot that can damage your liver and lungs, especially with long-term use. Chronic exposure can lead to veno-occlusive disease, a serious condition causing pain, vomiting, diarrhea, and liver enlargement. The product notes caution using only certified PA-free products — though the safest approach is to avoid coltsfoot altogether.
Does this product actually work for hay fever?
Wormwood is possibly effective for allergic rhinitis based on the evidence we have, but it's not well-established. The product safety notes say it's meant for short-term use only and shouldn't replace proven treatments for hay fever — talk with your pharmacist about options with stronger evidence.
What are the most common side effects?
Wormwood most commonly causes nausea and vomiting. Coltsfoot's main concern is liver and lung damage from its pyrrolizidine alkaloid content, which can develop over time with chronic use. One mild allergic reaction to wormwood (rash and cough) has been reported.
Is this product safe to use with my blood thinner?
No, not safely. Coltsfoot inhibits platelet aggregation and increases bleeding risk when combined with blood thinners like warfarin, heparin, or aspirin — these interactions are rated Moderate severity. Do not use this product if you take any blood thinner or antiplatelet drug without talking to your pharmacist first.
Can this product damage my liver?
Yes, potentially. Coltsfoot contains liver-toxic alkaloids that can cause veno-occlusive disease and liver damage with chronic use. Wormwood can also affect the liver, and there's additive risk if you combine it with other drugs that damage the liver. Avoid this product if you have liver disease or take medications that stress the liver.
