HelloPharmacist Scorecard of Hawthorn Berry by Herb Stop

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 1 active ingredient.

This product contains one active ingredient: hawthorn berry extract. In traditional use, hawthorn has been studied for heart and circulation support, though the evidence for specific conditions remains limited in our data.

The liquid also contains grape alcohol and water as inactive ingredients.

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 — see Hawthorn's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: support for healthy heart function.
  • We looked for evidence on: Angina, Arrhythmia, Cardiovascular disease (CVD), Congestive heart failure (CHF), Hypertension, chest pain — and 1 related terms.
  • The closest evidence on file: Hawthorn is rated "Insufficient Reliable Evidence To Rate" for Angina (Natural Medicines).
  • Also on file: Hawthorn is rated "Insufficient Reliable Evidence To Rate" for Arrhythmia, Cardiovascular disease (CVD), Congestive heart failure (CHF), Hypertension.

The evidence we hold shows insufficient reliable data to rate hawthorn for angina, anxiety, arrhythmia, atherosclerosis, cardiovascular disease, or cognitive function. That doesn't mean it doesn't work — it means larger, well-designed human studies haven't firmly established its benefit for these uses yet.

The evidence, ingredient by ingredient Hawthorn

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.

Hawthorn is generally well tolerated in studies, but because it affects the heart and blood vessels, it needs medical supervision if you have a heart condition. The facts don't provide enough safety information to recommend it during pregnancy or while breastfeeding — talk with your doctor or pharmacist about whether this is right for you.

Serious side effects are rare; the most common reports are minor, though palpitations and rapid heartbeat have been noted in a small number of trial participants with heart failure.

Side effects, ingredient by ingredient Hawthorn

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Hawthorn.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; heart-rhythm medications.
  • For scale: 191 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 doctor or pharmacist before taking this if you use nitrates or phosphodiesterase-5 inhibitors (Major interactions), or beta-blockers, blood thinners, calcium channel blockers, or digoxin (Moderate interactions). No other drug types require checking based on the data we hold.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Major medication interactions have been identified, and safety information is well characterized.

Hawthorn berry extract is a single-ingredient supplement generally well tolerated in studies, but it's not for you if you take medications for your heart, blood pressure, or blood clotting — those interactions are real and potentially serious. If you have any heart condition or take any cardiac medication, talk with your doctor or pharmacist before starting it.

Hawthorn Berry Extract6 drug types · 191 drugs

Nitrates

Theoretically, concomitant use might cause additive coronary vasodilatory effects.
Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects.

Likelihood Probable Evidence D
Phosphodiesterase-5 Inhibitors

Theoretically, concomitant use might result in additive vasodilation and hypotension.
Hawthorn might inhibit PDE-5 and cause vasodilation.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, hawthorn may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal research shows that hawthorn can inhibit platelet aggregation. However, its effect in humans is unclear. One observational study shows that patients taking hawthorn shortly before undergoing coronary artery bypass graft (CABG) surgery or valve replacement surgery have a 10% incidence of postoperative bleeding, compared with 1% in those who never consumed hawthorn extract. However, clinical research shows that taking a specific preparation of dried hawthorn leaves and flowers (Crataesor, Soria Natural Lab) 800 mg three times daily for 15 days does not affect platelet aggregation or levels of thromboxane B2, the metabolite of thromboxane A2, in healthy humans.

Likelihood Possible Evidence D
Beta-Blockers

Theoretically, concomitant use might cause additive effects on blood pressure and heart rate.
Some evidence shows that hawthorn might lower blood pressure and heart rate.

Likelihood Possible Evidence D
Calcium Channel Blockers

Theoretically, concomitant use might cause additive coronary vasodilation and hypotensive effects.
Some evidence shows that hawthorn might lower blood pressure due to vasodilatory effects.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, hawthorn might potentiate the effects and adverse effects of digoxin.
Hawthorn appears to improve cardiac output; however, hawthorn does not appear to affect digoxin pharmacokinetics. Case reports suggest that at least one species of hawthorn root extract (Crataegus mexicana) may produce adverse effects similar to digoxin and can cross-react with digoxin assays, leading to falsely elevated plasma digoxin levels.

Hawthorn Berry by Herb Stop: Common Questions

Does Hawthorn Berry by Herb Stop interact with any medications?
Yes. Based on its ingredients, Hawthorn Berry has a known interaction with 191 medications, including 14 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Hawthorn Berry 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 hawthorn if I'm pregnant or breastfeeding?
The safety data we have isn't enough to say either way. Talk with your doctor or pharmacist — they can weigh the risks and benefits for your situation.
What are the side effects?
Hawthorn is generally well tolerated. Serious side effects are rare; when they do occur, they might include an allergic-type reaction affecting the kidneys. Minor side effects reported in heart-failure studies include palpitations, rapid heartbeat, and respiratory symptoms like bronchitis, though these were uncommon.
Does hawthorn actually work for heart health?
We don't have enough reliable evidence to say whether it works for angina, arrhythmia, heart disease, or other cardiac conditions. That's why it needs medical oversight if you use it alongside heart medications.
Why is this dangerous with blood thinners?
Hawthorn may thin the blood further or increase bleeding risk — lab studies and animal research suggest it can slow blood clotting, though we don't have clear proof it does so in humans. Combined with a blood thinner, the risk rises.
Can I take this with my blood pressure medication?
It depends on the type. Beta-blockers and calcium channel blockers both lower blood pressure, and hawthorn may do the same — using them together could drop your pressure too far. Check with your doctor or pharmacist before combining them.
