HelloPharmacist Scorecard of Hawthorn Extract Plus by Earth Wise Vitamins & Supplements

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.

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 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Hawthorn Extract Plus contains three active ingredients. Hawthorn flower and leaf extract is the primary ingredient; cayenne fruit powder provides capsaicin, the compound that gives hot peppers their heat; and garlic bulb powder adds garlic's sulfur compounds.

All three have a long history in traditional and herbal medicine, particularly for cardiovascular support. The product is delivered in gelatin capsules.

Beyond the active ingredients, the label indicates there may be additional inactive ingredients present, though they are not fully listed here.

Does it work?

Moderate evidence
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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: support healthy blood pressure within normal range.
  • We looked for evidence on: Hypertension, cardiovascular health, blood pressure regulation.
  • The strongest evidence on file: Garlic is rated "Possibly Effective" for Hypertension (Natural Medicines).
  • Also on file: Hawthorn is rated "Insufficient Reliable Evidence To Rate" for Hypertension.
  • Also on file: Capsicum is rated "Insufficient Reliable Evidence To Rate" for Hypertension.

The evidence for hawthorn's effectiveness is not established in the data we hold — all its uses (angina, anxiety, arrhythmia, atherosclerosis, heart disease, and cognitive function) are rated insufficient reliable evidence. Cayenne shows more promise: it is likely effective for nerve pain after shingles (postherpetic neuralgia) and diabetic nerve pain, and possibly effective for cluster headaches, back pain, and nausea after surgery.

Garlic is possibly effective for periodontitis (gum disease), fatty liver disease, diabetes, high blood pressure, and atherosclerosis. Overall, the hawthorn component lacks strong evidence, while cayenne and garlic have modest support for specific uses.

The evidence, ingredient by ingredient Hawthorn Capsicum Garlic

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • 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 requires medical supervision because it affects the heart — serious allergic reactions affecting the kidneys are rare, and heart-related side effects (palpitations, irregular heartbeat, low heart rate) have been reported occasionally in people with heart failure. The product is not safe in pregnancy or while breastfeeding due to insufficient safety data.

Cayenne is generally well tolerated in food amounts and medicinal doses up to 200 mg daily; concentrated supplements beyond that are not well studied and should be avoided unless your doctor approves. Common side effects include burning in the stomach or gut, bloating, nausea, diarrhea, and sweating.

It is likely safe in pregnancy and lactation at food levels, but concentrated doses in pregnancy and breastfeeding are not well established. Garlic is generally well tolerated as food; concentrated supplement doses are not well studied and should not be used without your doctor's approval.

Common side effects are stomach upset, body odor, and bad breath. Garlic is likely safe in pregnancy and lactation at food amounts, but one ingredient rating suggests pregnancy risk — concentrated doses require your doctor's guidance.

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

Why this rating?
  • 3 of the 3 matched ingredients can interact with medications — Garlic, Hawthorn, Capsicum.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; heart-rhythm medications.
  • For scale: 1,009 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.

If you take any nitrates or phosphodiesterase-5 inhibitors (sildenafil, tadalafil, vardenafil), do not start this product without talking to your doctor — hawthorn carries a Major risk of dangerous blood pressure drops. Also double-check before using if you take beta-blockers, calcium channel blockers, or digoxin, blood thinners (warfarin, other anticoagulants, antiplatelet drugs like clopidogrel), blood pressure medications (especially ACE inhibitors and antihypertensive drugs), diabetes medications, aspirin, theophylline, ciprofloxacin, protease inhibitors (HIV drugs), tacrolimus, or any drug metabolized by liver enzymes — all carry Moderate or Minor severity risks with one or more ingredients here.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

This product may appeal to people interested in herbal support for heart and circulation, but because hawthorn and the other ingredients interact with many heart, blood pressure, and blood-thinning medications, and because hawthorn's own effectiveness is not established, anyone with a heart condition or taking prescription medications should clear it with their doctor or pharmacist first. It is not safe in pregnancy or breastfeeding.

If you decide to use it, have a conversation with your own healthcare provider about your specific medications and health situation.

Garlic bulb powder12 drug types · 989 drugs

Anticoagulant/Antiplatelet Drugs

Garlic may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Raw garlic and a variety of garlic extracts have antiplatelet activity and can increase prothrombin time.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, taking garlic with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research suggests that garlic and garlic extract lower blood glucose levels in healthy and diabetic individuals.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, taking garlic with antihypertensive drugs might increase the risk of hypotension.
In human research, both garlic and garlic extracts have blood pressure-lowering effects.

Likelihood Possible Evidence D
Atazanavir (Reyataz)

Theoretically, garlic might decrease levels and effects of atazanavir.
In a case report, a patient consuming six stir-fried garlic cloves three times weekly developed suboptimal atazanavir levels and increases in HIV viral load. While the exact cause of this interaction is unclear, there is speculation that garlic might decrease the intestinal absorption of atazanavir or increase its metabolism by inducing cytochrome P450 3A4 (CYP3A4). Until more is known, advise patients not to consume large amounts of garlic while taking atazanavir.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Garlic might increase levels of drugs metabolized by CYP2E1.
Clinical research suggests garlic oil can inhibit the activity of CYP2E1 by 39%. Use garlic oil cautiously in patients taking drugs metabolized by these enzymes.

Likelihood Probable Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, garlic products containing allicin might induce intestinal CYP3A4 and inhibit hepatic CYP3A4. This may increase or decrease levels of drugs metabolized by CYP3A4.
Some human research suggests that garlic may induce INTESTINAL CYP3A4, reducing levels of drugs metabolized by this enzyme. This is primarily based on a study showing that taking a specific allicin-containing garlic product (GarliPure Maximum Allicin Formula, Natrol Inc.) twice daily for 3 days reduces saquinavir levels by approximately 50%. It is speculated that the allicin constituent induced CYP3A4 in the gut mucosa. Another study shows that giving docetaxel intravenously, bypassing the CYP3A4 enzymes in the gut mucosa, along with the same specific garlic product for 12 consecutive days, does not affect docetaxel levels. Conversely, there is concern that garlic may inhibit HEPATIC CYP3A4. In a single case report, increased tacrolimus levels and liver injury occurred in a liver transplant patient after taking a specific garlic supplement (Garlicin Cardio, Nature's Way) at up to three times the manufacturer recommended dose for 7 days. Several other studies have evaluated the impact of other garlic formulations on CYP3A4 substrates and have found no effect. Most of the products in these studies provided little or no allicin.

Likelihood Possible Evidence B
Isoniazid

Theoretically, garlic might decrease levels of isoniazid.
Animal research suggests that an aqueous extract of garlic reduces isoniazid levels by about 65%. Garlic reduced the maximum concentration (Cmax) and area under the curve (AUC), but not the half-life, of isoniazid. This suggests that garlic extract might inhibit isoniazid absorption across the intestinal mucosa; however, the exact mechanism of this potential interaction is not known.

Likelihood Possible Evidence D
Protease Inhibitors (Pis)

Theoretically, garlic products containing allicin might decrease levels of PIs.
Protease inhibitors are metabolized by cytochrome P450 3A4 (CYP3A4) isoenzymes. There is concern that garlic products containing allicin might induce intestinal CYP3A4, reducing plasma levels of protease inhibitors. This is primarily based on a study showing that taking a specific garlic product (GarliPure Maximum Allicin Formula, Natrol Inc.) twice daily for 3 days reduces levels of saquinavir, a PI, by approximately 50%. It is speculated that the allicin constituent induce CYP3A4 in the gut mucosa. Several studies have evaluated the impact of other garlic formulations on CYP3A4 substrates and have found no effect. Most of the products in these studies provided little or no allicin.

Likelihood Possible Evidence B
Saquinavir (Fortovase, Invirase)

Theoretically, garlic containing allicin might decrease levels of saquinavir.
Saquinavir is a substrate of cytochrome P450 3A4 (CYP3A4) isoenzymes. There is concern that garlic products containing allicin might induce intestinal CYP3A4 and cause subtherapeutic levels of saquinavir. This is primarily based on a pharmacokinetic study showing that taking a specific garlic product (GarliPure Maximum Allicin Formula, Natrol Inc.) twice daily for 3 days reduces saquinavir levels by approximately 50%. It is speculated that the allicin constituent induces CYP3A4 in the gut mucosa. Several pharmacokinetic studies have evaluated the impact of other garlic formulations on CYP3A4 substrates and have found no effect. Most of the products in these studies provided little or no allicin. Until more is known about this potential interaction, use garlic containing allicin cautiously in patients taking saquinavir.

Likelihood Possible Evidence B
Sofosbuvir (Sovaldi)

Theoretically, taking garlic with sofosbuvir might decrease its effectiveness.
Animal research in rats shows that giving aged garlic extract 120 mg/kg orally daily for 14 days decreases the area under the concentration time curve (AUC) after a single sofosbuvir dose of 40 mg/kg by 36%, increases the clearance by 63%, and decreases the plasma concentrations at 1 and 8 hours by 35% and 58%, respectively. This interaction is hypothesized to be due to induction of intestinal P-glycoprotein expression by garlic.

Likelihood Possible Evidence D
Tacrolimus (Prograf)

Theoretically, garlic might increase levels of tacrolimus.
In one case report, a liver transplant patient taking tacrolimus experienced increased tacrolimus levels and liver injury after taking a specific garlic supplement (Garlicin Cardio, Nature's Way) at up to three times the manufacturer recommended dose for 7 days. It is speculated that garlic inhibited hepatic cytochrome P450 3A4 (CYP3A4), which increased plasma levels of tacrolimus.

Likelihood Possible Evidence B
Warfarin (Coumadin)

Theoretically, garlic might increase the risk of bleeding with warfarin.
Raw garlic and a variety of garlic extracts have antiplatelet activity and can increase prothrombin time. In addition, there is a report of two patients who experienced an increase in a previously stabilized international normalized ratio (INR) with concomitant garlic and warfarin use. However, this report has been subsequently debated due to limited clinical information. Other clinical studies have not identified an effect of garlic on INR, warfarin pharmacokinetics, or bleeding risk. More evidence is needed to determine the safety of using garlic with warfarin.

Likelihood Possible Evidence D
Garlic bulb powder full monograph & interactions

Cayenne fruit powder6 drug types · 239 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, capsicum may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro research shows that capsicum might increase the effects of antiplatelet drugs. Also, population research shows that capsicum is associated with an increased risk of self-reported bleeding in patients taking warfarin. However, clinical research shows that taking a single dose of capsaicin (Asian Herbex Ltd.), the active ingredient in capsicum, 400-800 mcg orally in combination with aspirin 500 mg does not decrease platelet aggregation when compared with taking aspirin 500 mg alone. Also, there was no notable effect on measures of platelet aggregation with capsaicin. It is unclear whether capsaicin must be used in more than a single dose to affect platelet aggregation.

Likelihood Possible Evidence B
Antidiabetes Drugs

Theoretically, taking capsicum with antidiabetes drugs might increase the risk of hypoglycemia.
Preliminary clinical research shows that consuming capsicum 5 grams along with a glucose drink attenuates the rise in plasma glucose after 30 minutes by 21%, decreases the 2-hour postprandial area under the curve of plasma glucose by 11%, and increases the 2-hour postprandial area under the curve of plasma insulin by 58% in healthy individuals when compared with placebo. Other clinical research shows that taking capsicum 5 mg daily for 28 days significantly reduces postprandial blood glucose and insulin levels, but not fasting blood glucose and insulin levels, in patients with gestational diabetes.

Likelihood Possible Evidence B
Aspirin

Theoretically, taking capsicum with aspirin might reduce the bioavailability of aspirin.
Animal research shows that acute or chronic intake of capsicum pepper reduces oral aspirin bioavailability. This has not been shown in humans.

Likelihood Possible Evidence D
Theophylline

Theoretically, taking capsicum with theophylline might increase the levels and adverse effects of theophylline.
In animal research, oral administration of capsicum reduced excretion of theophylline. However, capsicum does not seem to affect the pharmacokinetics of theophylline when administered intravenously.

Likelihood Possible Evidence D
Ace Inhibitors (Aceis)

Theoretically, using topical capsaicin may increase the risk of ACE inhibitor-induced cough.
There is one case report of a topically applied capsaicin cream contributing to the cough reflex in a patient using an ACEI. However, it is unclear if this interaction is clinically significant.

Likelihood Unlikely Evidence D
Ciprofloxacin (Cipro)

Theoretically, taking capsicum with ciprofloxacin might increase levels and adverse effects of ciprofloxacin.
Animal research shows that concomitant use of capsaicin, the active constituent of capsicum, and ciprofloxacin increases the bioavailability of ciprofloxacin by up to 70%.

Likelihood Possible Evidence D
Cayenne fruit powder full monograph & interactions

Hawthorn flower and leaf 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 Extract Plus by Earth Wise Vitamins & Supplements: Common Questions

Does Hawthorn Extract Plus by Earth Wise Vitamins & Supplements interact with any medications?
Yes. Based on its ingredients, Hawthorn Extract Plus has a known interaction with 1,008 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 Extract Plus contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 Extract Plus if I'm pregnant or breastfeeding?
No — hawthorn safety data is not sufficient, and the product advises against it in both pregnancy and breastfeeding. Talk to your doctor or pharmacist about what's safe for you at this stage.
Does hawthorn actually work for heart problems?
The evidence we have on file rates hawthorn's effectiveness as insufficient for angina, arrhythmia, heart disease, and other cardiac uses — we don't have strong data to say it works for those purposes. The other two ingredients (cayenne and garlic) do have some evidence for specific conditions, but hawthorn's role here is unclear.
What are the most common side effects?
Hawthorn is generally well tolerated. Cayenne commonly causes stomach burning, bloating, nausea, diarrhea, and sweating. Garlic causes stomach upset, body odor, and bad breath. Serious side effects are rare with all three.
Can I take this with my blood thinner?
All three ingredients in this product — hawthorn, cayenne, and garlic — carry a Moderate interaction with blood thinners, meaning they may increase bleeding risk. Do not use this product with warfarin, other anticoagulants, or antiplatelet drugs without checking with your doctor first.
Can I use this if I take a blood pressure medication?
Hawthorn, cayenne, and garlic can all lower blood pressure, and hawthorn specifically interacts with blood pressure drugs (beta-blockers, calcium channel blockers, ACE inhibitors) at a Moderate level. Check your exact medications with your doctor or pharmacist before starting.
Is this product safe if I have a heart condition?
Hawthorn can affect heart rate and blood pressure, so if you have a heart condition you're being treated for, you need your doctor's or pharmacist's OK before starting — this is not something to take on your own in that situation.
