HelloPharmacist Scorecard of Hawthorne 300 mg Extended Release by Natures Plus Herbal Actives

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, a plant extract traditionally used in herbal cardiology. Natures Plus delivers 300 mg per tablet in an extended-release form, so it releases into your system over time rather than all at once.

The tablet also contains several inactive ingredients—di-calcium phosphate, stearic acid, microcrystalline cellulose, hydroxypropyl methylcellulose, magnesium stearate, silica, and pharmaceutical glaze—which help bind and deliver the hawthorn.

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: nutritional support for healthy heart function.
  • We looked for evidence on: Angina, Arrhythmia, Cardiovascular disease (CVD), Congestive heart failure (CHF), Hypertension, coronary artery disease — 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 for hawthorn's effectiveness hasn't been established for most conditions we hold data on. Our monograph rates it as insufficient reliable evidence for angina, anxiety, arrhythmia, atherosclerosis, cardiovascular disease, and cognitive function.

That doesn't mean it doesn't work—it means the rigorous trial data to prove it isn't in the research we've reviewed.

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, medical supervision is important if you have a heart condition. Safety information during pregnancy and breastfeeding is not adequate, so it's best avoided during both.

Serious adverse effects are rare. Most people experience no problems, though a small number in trials have reported palpitations, bronchitis, or changes in heart rate.

An extremely rare allergic reaction affecting multiple organs and the kidneys has been reported.

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 you start this product, check with your doctor or pharmacist if you take nitrates or phosphodiesterase-5 inhibitors—hawthorn could dangerously lower your blood pressure. Also verify any beta-blockers, calcium channel blockers, blood thinners (anticoagulants or antiplatelet drugs), or digoxin you're on, as hawthorn may alter how they work.

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 is a single-ingredient herbal supplement for people interested in cardiovascular support, but it's not proven effective for most conditions. It's not appropriate if you take heart medications, blood pressure drugs, blood thinners, or certain other prescriptions without clearing it first with your doctor or pharmacist.

If you have a heart condition, you need medical supervision while taking it.

Hawthorne6 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.

Hawthorne 300 mg Extended Release by Natures Plus Herbal Actives: Common Questions

Does Hawthorne 300 mg Extended Release by Natures Plus Herbal Actives interact with any medications?
Yes. Based on its ingredients, Hawthorne 300 mg Extended Release 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?
Hawthorne 300 mg Extended Release 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 about hawthorn during pregnancy and breastfeeding, so the data advises against it. Talk to your doctor or pharmacist before taking it if you're pregnant, planning to become pregnant, or nursing.
What is hawthorn supposed to do?
Hawthorn is traditionally used to support cardiovascular health. However, we don't have reliable evidence that it works for conditions like angina, arrhythmia, atherosclerosis, or cardiovascular disease.
What side effects might hawthorn cause?
Most people tolerate it well. A small number of trial participants reported palpitations or changes in heart rate. Very rare cases of serious allergic reactions affecting the kidneys and multiple organs have been reported. Bronchitis and breathing changes have also been noted in a few cases.
Why does this product interact with so many heart medications?
Hawthorn appears to relax and widen blood vessels, which is why it can add to or enhance the effects of medications that do the same—like blood pressure drugs, heart rate medications, and blood thinners. That overlap is why checking your prescriptions first matters.
Is hawthorn safe if I have a heart condition?
Hawthorn is generally well tolerated, but because it affects the heart and blood vessels, you need medical supervision if you have a heart condition. Don't start it on your own—check with your doctor first.
