HelloPharmacist Scorecard of Hawthorn by Herbs Etc.

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: fresh Hawthorn Berry. Hawthorn has been traditionally used to support heart health and circulation.

The liquid is delivered in a base of 50% grain alcohol and purified water.

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

This is a single-ingredient Hawthorn product and its label doesn't state a use — see Hawthorn's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for hawthorn's effectiveness in the conditions on file — angina, anxiety, arrhythmia, atherosclerosis, cardiovascular disease, and cognitive function — is insufficient to rate. That means we don't have enough reliable data yet to say whether it works for any of these uses.

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 when used as directed. However, because it affects the heart, anyone with a heart condition should use it only under medical supervision.

Serious adverse effects are rare, but multiorgan hypersensitivity reactions leading to kidney failure have been reported occasionally. A small number of people have reported heart palpitations or irregular heartbeats in large trials and case reviews.

There isn't enough safety information to recommend hawthorn during pregnancy or while breastfeeding — talk with your doctor or pharmacist about whether it's right for you in those situations.

Side effects, ingredient by ingredient Hawthorn

Meds to double-check

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 using this product if you take nitrates or PDE-5 inhibitors (Major severity risk of dangerously low blood pressure), or beta-blockers, blood thinners, calcium channel blockers, or digoxin (Moderate severity risks). This product significantly affects heart function and blood pressure, so any cardiac medication deserves a conversation first.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.

Hawthorn may appeal to someone interested in traditional heart-health support, but it's not for you if you take nitrates, PDE-5 inhibitors, beta-blockers, blood thinners, calcium channel blockers, or digoxin without checking first. Because hawthorn affects the heart and blood pressure, anyone with heart disease or taking cardiac medications should talk it over with their doctor or pharmacist before starting it.

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.

Yes. Based on its ingredients, Hawthorn 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 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.
What is hawthorn used for?
Hawthorn has been used traditionally to support heart health and circulation. However, the evidence for its effectiveness in angina, anxiety, arrhythmia, atherosclerosis, cardiovascular disease, and cognitive function is insufficient — meaning we don't have enough reliable data yet to say it works for these uses.
Is hawthorn safe during pregnancy or breastfeeding?
There isn't enough safety information to recommend hawthorn during pregnancy or breastfeeding. Talk with your doctor or pharmacist about your individual situation before taking it.
What are the side effects of hawthorn?
Hawthorn is generally well tolerated when used appropriately. Serious side effects are rare, but multiorgan hypersensitivity reactions leading to kidney failure have been reported occasionally. A small number of people have reported heart palpitations or irregular heartbeats in large trials.
Can I take hawthorn if I have a heart condition?
Because hawthorn affects the heart and blood pressure, you need medical supervision if you have a heart condition. Do not start it without talking to your doctor or pharmacist first.
Does this product contain alcohol?
Yes, this liquid product is 50% grain alcohol. Keep that in mind if you avoid alcohol or take medications that interact with it.
