HelloPharmacist Scorecard of Red Raspberry by Herb Pharm

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 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: red raspberry leaf (Rubus idaeus) extract in liquid form. The extract is suspended in certified organic cane alcohol and distilled water.

Does it work?

No specific claim
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
General wellness

This Red Raspberry product is marketed for general wellness, not a specific health condition, so there's no single claim to grade — see Red Raspberry's own graded uses on its monograph.

Why this rating?
  • The label markets general wellness (“optimal well-being”), not a specific health condition, so there is no single claim to grade against clinical-evidence data.

The evidence for red raspberry leaf's effectiveness isn't yet established in our data. It's been studied for aging skin, cardiovascular disease, respiratory tract infections, congestive heart failure, and diabetes, but current research shows insufficient reliable evidence to rate it as effective for any of these purposes.

If you're considering it for a specific health goal, talk it over with your doctor or pharmacist about whether the evidence supports its use for your situation.

The evidence, ingredient by ingredient Red Raspberry

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.

Red raspberry leaf is generally well tolerated by most adults, though safety evidence is limited overall. The most common side effects reported are diarrhea, gastrointestinal upset, and epigastric pain (pain in the upper abdomen)—but these don't usually happen at typical doses.

A rare case of occupational asthma from inhaling red raspberry powder has been reported. Pregnancy and breastfeeding safety isn't well established: while it's often used in late pregnancy, you'll want to use it only under your healthcare provider's guidance, and there isn't enough reliable data to confirm it's safe while breastfeeding.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Red Raspberry.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 135 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 product, double-check with your doctor or pharmacist if you take any anticoagulant or antiplatelet drugs—blood thinners like warfarin, apixaban, or clopidogrel (Moderate risk of increased bleeding). Also confirm if you're on insulin for diabetes, as red raspberry leaf might lower your blood glucose levels (Moderate risk).

Run your exact medications through the interaction checker on this page to be sure.

The bottom line

Scorecard at a glanceFully disclosed formula marketed for general wellness rather than one specific gradeable purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Red Raspberry by Herb Pharm is generally well tolerated at standard doses, but it's not appropriate if you take blood thinners or insulin without checking first—the interaction risks are real. If you're pregnant, breastfeeding, or managing diabetes or heart concerns, talk with your doctor or pharmacist before starting it to make sure it fits your situation.

Anticoagulant/Antiplatelet Drugs

Theoretically, taking red raspberry leaf with anticoagulant/antiplatelet drugs might increase the risk of bleeding.
In vitro research suggests that red raspberry leaf extract has antiplatelet activity and enhances the in vitro effects of the antiplatelet medication cangrelor. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Insulin

Red raspberry leaf might reduce glucose levels in patients being treated with insulin.
In one case report, a 38-year-old patient with gestational diabetes, whose blood glucose was being controlled with medical nutrition therapy and insulin, developed hypoglycemia after consuming two servings of raspberry leaf tea daily for 3 days beginning at 32 weeks' gestation. The patient required an insulin dose reduction. The hypoglycemia was considered to be probably related to use of red raspberry leaf tea.

Red Raspberry by Herb Pharm: Common Questions

Does Red Raspberry by Herb Pharm interact with any medications?
Yes. Based on its ingredients, Red Raspberry has a known interaction with 135 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Red Raspberry 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.
Is it safe to take this while I'm on warfarin or another blood thinner?
Not without checking with your doctor first. Red raspberry leaf extract can enhance the blood-thinning effect of these medications and may increase your bleeding risk. Your doctor or pharmacist needs to review your specific situation and dosing before you add it.
Will this lower my blood sugar if I'm on insulin?
It might. There's a documented case of a patient developing low blood sugar after drinking raspberry leaf tea daily while on insulin. If you use insulin for diabetes, confirm with your doctor or pharmacist that it's safe to combine, and monitor your glucose closely if you do take it.
Can I take this while pregnant?
Red raspberry leaf is often used in late pregnancy, but safety isn't well established. Don't start it on your own—talk with your obstetrician or midwife first to see if it's right for your pregnancy.
Can I take this while breastfeeding?
We don't have enough reliable data to confirm it's safe while breastfeeding. Check with your doctor or pharmacist before using it if you're nursing.
What are the common side effects?
Diarrhea, gastrointestinal upset, and upper abdominal pain are the most commonly reported, but these don't usually occur at typical doses. A rare case of asthma-like symptoms from inhaling the powder has been documented.
Does this actually work for anything?
The research we have shows insufficient evidence to rate its effectiveness for the conditions it's been studied in—aging skin, heart health, respiratory infections, and diabetes among them. If you're considering it for a specific reason, your doctor can discuss what the current evidence actually supports.
