HelloPharmacist Scorecard of Hawthorn 1050 mg by Solaray

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

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: hawthorn berry extract at 1,050 mg per capsule. The inactive ingredients are cellulose, magnesium stearate, and a rice extract blend — these are the capsule material and binders that hold it together.

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: herbal support for heart health.
  • We looked for evidence on: Angina, Arrhythmia, Congestive heart failure (CHF), Hypertension, Cardiovascular disease (CVD), Chest pain — and 2 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 for hawthorn's effectiveness isn't established in the data we hold. We have insufficient reliable evidence to rate it for angina, anxiety, arrhythmia, atherosclerosis, cardiovascular disease, or cognitive function.

That doesn't mean it doesn't work — it means the research to support or refute those uses isn't solid enough 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 when used as directed, but because it affects your heart and blood pressure, any heart condition needs medical supervision. Serious adverse effects are rare, though multiorgan hypersensitivity reactions with kidney problems have been reported in isolated cases.

A small number of people have reported heart palpitations or changes in heart rhythm in large trials. There isn't enough safety information to know whether hawthorn is safe during pregnancy or while breastfeeding — the data advises against use in both situations.

Talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or nursing.

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 you take this, double-check any nitrates or phosphodiesterase-5 inhibitors you're on (Major severity). Also screen for beta-blockers, blood thinners, calcium channel blockers, or digoxin — all Moderate severity.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Major medication interactions have been identified, and safety information is well characterized.

Hawthorn may appeal to people looking for traditional heart support, but it's not a replace-your-doctor's-care supplement — especially if you have a heart condition or take heart medications. The interaction list is long and serious.

Check your exact medications with the tool on this page, and talk with your pharmacist or doctor before starting.

Formula

Hawthorn 1050 mg per serving

Discussion: Hawthorn, also known as mayflower or may bush, is a dense, thorny shrub in the rose family. Native to northern climates, hawthorn is one of the oldest medicinal plants in Europe with a rich history. In Celtic folklore, hawthorn was believed to mend a broken heart and protect your home from evil spirits. Recent studies suggest that hawthorn may support cardiovascular function and help maintain normal, healthy blood pressure levels.

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 1050 mg by Solaray: Common Questions

Does Hawthorn 1050 mg by Solaray interact with any medications?
Yes. Based on its ingredients, Hawthorn 1050 mg 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 1050 mg 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?
There isn't enough safety information to know either way. The data advises against it during pregnancy and breastfeeding. Talk with your doctor or pharmacist for personalized advice.
Does hawthorn actually work for heart health?
The evidence we hold is insufficient to rate it for cardiovascular disease, angina, arrhythmias, or other heart conditions. That means the research isn't solid enough yet to say yes or no.
What side effects should I watch for?
Most people tolerate it well. Rarely, heart palpitations or changes in rhythm have been reported. Very rarely, multiorgan reactions affecting the kidneys have occurred. If your heart feels off or you have trouble breathing, stop and call your doctor.
Why does hawthorn interact with so many heart medications?
Hawthorn affects blood pressure and how your blood vessels work — the same way many heart drugs do. When you combine them, the effects can add up and become unsafe.
