HelloPharmacist Scorecard of Inflammation Control Powder by TerraVita Premium Collection

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 2 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

This powder contains two active ingredients: devil's claw and boldo. Devil's claw is traditionally used for joint and back pain.

Boldo is a plant extract historically used for digestive and gallbladder health, though the evidence for it is limited. The product contains no inactive fillers or other added ingredients — just the two botanicals themselves.

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 for joint health and inflammation.
  • We looked for evidence on: Back pain, Joint pain, Osteoarthritis, Rheumatoid arthritis (RA), musculoskeletal inflammation, inflammatory pain.
  • 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: Boldo is rated "Insufficient Reliable Evidence To Rate" for Joint pain.

For devil's claw, the data shows possibly effective evidence for back pain and osteoarthritis, meaning some research supports it but more evidence would strengthen the case. For atherosclerosis, there isn't enough reliable evidence to know whether it works.

Boldo's effectiveness isn't well established in the data we hold — we have insufficient evidence for benign prostatic hyperplasia, gallbladder disease, kidney stones, and joint pain. That means the science hasn't yet backed up its traditional uses in a way we can point to with confidence.

The evidence, ingredient by ingredient Devil's Claw Boldo

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Both ingredients are generally well tolerated when used short-term in healthy adults, though devil's claw commonly causes digestive upset like diarrhea, indigestion, and allergic skin reactions. Rarely, gastrointestinal bleeding has been reported.

Boldo carries a more serious safety concern: its ascaridole content can harm your liver, and cases of elevated liver enzymes and jaundice have been documented. Boldo may also cause nausea, vomiting, and abdominal pain.

During pregnancy, devil's claw is rated possibly unsafe because it may affect the uterus and its safety hasn't been established; boldo is also rated possibly unsafe and may stimulate the uterus. Neither ingredient has enough safety data to recommend use while breastfeeding — talk with your doctor or pharmacist about what's right for you if you're pregnant, planning to become pregnant, or nursing.

Side effects, ingredient by ingredient Devil's Claw Boldo

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?
  • 2 of the 2 matched ingredients can interact with medications — Boldo, Devil's Claw.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; lithium.
  • For scale: 1,049 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 powder, check with your doctor or pharmacist if you take any of the following: blood thinners or antiplatelet drugs like warfarin (increased bleeding risk from both ingredients); drugs broken down by your liver's CYP2C19, CYP2C9, or CYP3A4 systems (devil's claw may raise their levels); lithium (boldo may increase it to harmful levels); tacrolimus (boldo may lower it, risking transplant rejection); or any drugs that can damage the liver (boldo compounds that risk). Also check if you take acid-blocking medications like H2-blockers or proton pump inhibitors, where devil's claw may reduce their effectiveness.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product may help with back pain or osteoarthritis based on devil's claw's evidence, but it comes with significant interaction risks — especially if you take blood thinners, liver-damaging drugs, lithium, or tacrolimus — and boldo carries real hepatotoxicity concerns. If you're on any prescription medications or have liver disease, talk with your doctor or pharmacist before starting this product.

Devils Claw, Powder7 drug types · 804 drugs

Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, devil's claw might increase levels of drugs metabolized by CYP2C19.
In vitro research shows that devil's claw might inhibit CYP2C19, although this has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, devil's claw might increase levels of drugs metabolized by CYP2C9.
In vitro research shows that devil's claw might inhibit CYP2C9, although this has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, devil's claw might increase levels of drugs metabolized by CYP3A4.
In vitro research shows that devil's claw might inhibit CYP3A4, although this has not been reported in humans.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, Devil's claw might increase the activity of warfarin.
In one case report, purpura occurred in a patient taking warfarin and devil's claw concurrently. This might indicate over-anticoagulation. It is unclear if this was due to Devil's claw or other contributing factors.

Likelihood Possible Evidence D
H2-Blockers

Theoretically, devil's claw might decrease the effectiveness of H2-blockers.
Devil's claw has been reported to increase stomach acid, which might interfere with the effects of H2-blockers.

Likelihood Possible Evidence D
P-Glycoprotein Substrates

Theoretically, devil's claw might increase levels of P-glycoprotein substrates.
In vitro research shows that devil's claw inhibits P-glycoprotein, which transports many drugs out of cells. This might increase intracellular levels of P-glycoprotein substrates, although it is unclear if this effect would be clinically important.

Likelihood Possible Evidence D
Proton Pump Inhibitors (Ppis)

Theoretically, devil's claw might decrease the effectiveness of PPIs.
Devil's claw has been reported to increase stomach acid, which might interfere with the effects of PPIs.

Likelihood Possible Evidence D

Boldo, Powder5 drug types · 482 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, taking boldo with anticoagulant/antiplatelet drugs might increase the risk of bleeding.
Animal and in vitro research shows that boldine, a constituent of boldo, has antiplatelet activity. In one case report, an adult taking a combination of boldo and fenugreek with warfarin experienced an increase in international normalized ratio (INR); however, it is unclear if this effect was due to boldo, fenugreek, the combination, or another factor.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, taking boldo with hepatotoxic drugs might increase the risk of hepatic injury and disease.
Boldo leaf contains ascaridole, a known liver toxin. Many cases of hepatotoxicity, including elevated liver transaminase levels and jaundice, have been reported in patients taking boldo.

Likelihood Possible Evidence D
Lithium

Theoretically, taking boldo with lithium might increase the levels and clinical effects of lithium.
Boldo is believed to have diuretic effects. Theoretically, these diuretic effects might reduce the excretion of lithium. The dose of lithium might need to be decreased.

Likelihood Probable Evidence D
Tacrolimus (Prograf)

Taking boldo with tacrolimus may decrease the levels and clinical effects of tacrolimus, potentially increasing the risk of transplant rejection.
In one case report, a patient with a long-term history of stable tacrolimus levels developed subtherapeutic levels after taking boldo 300 mg twice daily orally for several weeks. Tacrolimus levels returned to normal after discontinuing boldo. However, the mechanism of this interaction is unclear.

Likelihood Possible Evidence D
Warfarin (Coumadin)

A combination of boldo and fenugreek was thought to be associated with an increased international normalized ratio (INR) in a female on warfarin. It is not clear if boldo, fenugreek, or the combination played a role in this interaction. Therefore, boldo may have additive effects with warfarin.

Inflammation Control Powder by TerraVita Premium Collection: Common Questions

Does Inflammation Control Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Inflammation Control Powder has a known interaction with 1,048 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Inflammation Control Powder contains 2 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.
Does devil's claw actually work for back pain and arthritis?
The evidence suggests it possibly works for both back pain and osteoarthritis — meaning some research supports it, but we'd like to see more. You won't know if it helps you personally until you try it, and that's a conversation to have with your doctor or pharmacist, especially if you're on other medications.
What are the most common side effects I might notice?
Devil's claw most often causes digestive complaints like diarrhea, indigestion, and nausea. Boldo can cause nausea, vomiting, and abdominal pain. Both are generally well tolerated in the short term, but if your stomach troubles you or you notice yellowing of the skin or eyes, stop and talk with your doctor right away.
Is it safe to take if I'm pregnant or breastfeeding?
No — both devil's claw and boldo are rated possibly unsafe in pregnancy because they may affect the uterus and safety hasn't been established. Neither has enough safety data for breastfeeding either. If you're pregnant, planning pregnancy, or nursing, talk with your doctor or pharmacist before considering this product.
Why does this product have such a high medication interaction count?
Devil's claw theoretically affects a broad class of drugs your liver breaks down (CYP2C19, CYP2C9, and CYP3A4 substrates), and that class includes hundreds of different medications. Boldo adds interactions with blood thinners, lithium, and tacrolimus. The high number reflects how many individual drugs fall into those categories, not that every medication will be affected.
What's the biggest safety concern with boldo in this product?
Boldo contains ascaridole, a liver toxin. Cases of elevated liver enzymes and jaundice have been reported with boldo use, especially at medicinal doses. If you have liver disease or take other drugs that stress your liver, this ingredient poses a real risk — check with your doctor or pharmacist first.
Can I take this with my other supplements?
That depends entirely on what they are — we can't answer that without knowing the specifics. Talk with your pharmacist about your full supplement and medication list before adding this product.
