HelloPharmacist Scorecard of Devil's Claw Root Strawberry Flavor by TerraVita

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 Jul 23, 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: devil's claw root as a glycerite liquid extract. Devil's claw is a plant root traditionally used for joint and muscle discomfort.

The product also contains glycerin and strawberry flavor as inactive ingredients to make it palatable.

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: joint pain and inflammation relief.
  • We looked for evidence on: Back pain, Osteoarthritis, Rheumatoid arthritis (RA), Tendinopathy, Fibromyalgia, Myalgia — and 3 related terms.
  • The strongest evidence on file: Devil's Claw is rated "Possibly Effective" for Back pain (Natural Medicines).
  • Also on file: Devil's Claw is rated "Possibly Effective" for Osteoarthritis.
  • Also on file: Devil's Claw is rated "Insufficient Reliable Evidence To Rate" for Fibromyalgia, Myalgia, Rheumatoid arthritis (RA), Gout, and more.

Devil's claw has possibly effective evidence for back pain and osteoarthritis — meaning some good research supports its use, but more studies would strengthen the case. We don't hold enough reliable evidence to rate it for atherosclerosis.

The evidence, ingredient by ingredient Devil's Claw

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.

Devil's claw is generally well tolerated for short-term use in healthy adults, but it does come with caveats. The most common side effects are allergic skin reactions, diarrhea, and indigestion — mild gastrointestinal upset happens in roughly 9 to 18 percent of people taking certain devil's claw extracts, and a small number report headache, ringing in the ears, loss of taste, dizziness, or difficulty sleeping.

Rare cases of gastrointestinal bleeding have been reported. Avoid this product during pregnancy — it may affect the uterus and safety has not been established.

Also avoid it while breastfeeding because there isn't enough safety information. If you're pregnant or nursing, talk with your doctor or pharmacist about whether this product is right for you.

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 — Devil's Claw.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 805 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.

Check with your doctor or pharmacist before using this product if you take medications broken down by your liver (including many statins, some blood pressure drugs, and certain antidepressants), blood thinners like warfarin, or acid-reflux medications (H2-blockers like famotidine or omeprazole-type drugs). The interactions are lab-based theory rather than proven in people, but they're serious enough to confirm your specific drugs are safe.

The bottom line

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

If you have back pain or osteoarthritis and are looking for a plant-based option, devil's claw has some research backing it. But before you start, check your medications with the tool on this page — the interactions are theoretical but span a lot of drugs.

Avoid it if you're pregnant, nursing, or taking a blood thinner like warfarin. Talk it over with your own doctor or pharmacist first.

Devil's Claw Root Strawberry Flavor by TerraVita: Common Questions

Does Devil's Claw Root Strawberry Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Devil's Claw Root Strawberry Flavor has a known interaction with 804 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Devil's Claw Root Strawberry Flavor 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 devil's claw while I'm on warfarin?
Not without checking with your doctor first. Devil's claw may theoretically increase warfarin's blood-thinning effect, and there's one case report of bleeding under the skin when the two were taken together. Your doctor needs to know before you add this product.
What are the most common side effects?
Mild stomach upset, diarrhea, and skin allergies are the most common. Indigestion shows up in about 9 to 18 percent of people taking certain devil's claw extracts. Rare cases of gastrointestinal bleeding have been reported.
Is it safe to take devil's claw if I'm pregnant?
No — the safety data advises against it because devil's claw may affect the uterus and safety has not been established. Talk with your doctor or pharmacist for personalized advice.
Can I use this while breastfeeding?
There isn't enough safety information to know whether it's safe while breastfeeding, so it's best to avoid it. Your doctor or pharmacist can discuss safer options with you.
Does devil's claw actually work for back pain?
The research suggests it's possibly effective — meaning some good studies support its use for back pain — but we'd like to see more evidence. Results vary from person to person.
What happens if I take this with my heartburn medication?
Devil's claw may theoretically increase stomach acid, which could reduce how well your acid-reflux medication (like omeprazole or famotidine) works. It's a Minor-severity interaction, but mention it to your pharmacist or doctor so they can monitor you.
