HelloPharmacist Scorecard of Hawthorn by BIOVEA

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 Aug 6, 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 contains one active ingredient: organic hawthorn. The liquid also includes grain alcohol and deionized water as inactive ingredients.

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 we hold does not establish that hawthorn is effective for the conditions listed—angina, anxiety, arrhythmia, atherosclerosis, cardiovascular disease, or cognitive function. All are rated insufficient reliable evidence to rate, meaning the data available isn't strong enough to confirm a benefit.

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 when taken by mouth at appropriate doses, but because it affects the heart, any use needs medical supervision if you have a heart condition. The safety data advises against use during pregnancy and while breastfeeding—there isn't enough information to know it's safe in those situations.

Serious side effects are rare; the main reported concerns are occasional palpitations, faster heart rate, or breathing changes. A very rare multiorgan allergic reaction affecting the kidneys has been reported.

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.

Before taking this hawthorn product, check with your doctor or pharmacist if you take nitrates or phosphodiesterase-5 inhibitors (Major severity)—the combination could dangerously lower your blood pressure. Also double-check if you're on beta-blockers, calcium channel blockers, blood thinners, or digoxin (all Moderate severity), as hawthorn may amplify their effects.

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.

Hawthorn may be worth considering if you're interested in heart health support, but it's not a first choice unless your doctor recommends it—the evidence for its effectiveness isn't established in our data. If you have heart disease, take blood pressure or heart medications, or are pregnant or breastfeeding, talk with your doctor or pharmacist before starting.

Because of its interactions with cardiac drugs, it's not something to add on your own.

organic Hawthorn6 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 by BIOVEA: Common Questions

Does Hawthorn by BIOVEA interact with any medications?
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.
Can I take hawthorn if I'm on blood pressure medication?
Not without checking first. Hawthorn lowers blood pressure on its own, so combining it with blood pressure drugs like beta-blockers or calcium channel blockers could drop your pressure too low. Talk with your doctor or pharmacist before adding it.
Is hawthorn safe during pregnancy or breastfeeding?
The safety data advises against it—there isn't enough information to know either way. If you're pregnant or breastfeeding and interested in hawthorn, talk with your doctor or pharmacist for personalized advice.
What does hawthorn actually do?
We don't have reliable evidence that hawthorn works for the conditions listed on this page—angina, anxiety, arrhythmia, atherosclerosis, cardiovascular disease, or cognitive function. That doesn't mean it does nothing, just that the data we hold doesn't establish it.
What are the side effects?
Hawthorn is generally well tolerated, but some people have reported palpitations, faster heart rate, or breathing changes. A very rare serious allergic reaction affecting the kidneys has been reported. Because it affects your heart, any use should be supervised by a doctor if you have heart disease.
Can I take hawthorn with aspirin or other blood thinners?
Hawthorn may increase bleeding risk if combined with blood thinners or antiplatelet drugs like aspirin. Check with your doctor or pharmacist before using it alongside these medications.
