HelloPharmacist Scorecard of Samento by NutraMedix

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.

Samento is a single-ingredient liquid supplement — just cat's claw bark extract. The extract contains alkaloids like rhynchophylline and isorhynchophylline, which are the compounds responsible for most of its effects in the body.

The liquid is made with mineral water and ethanol as inactive ingredients.

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 Cat's Claw's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Immune and microbial support.
  • We looked for evidence on: Chronic fatigue syndrome (CFS), Inflammatory bowel disease (IBD), Osteoarthritis, Rheumatoid arthritis (RA), Infection resistance, Microbiome health.
  • The closest evidence on file: Cat's Claw is rated "Insufficient Reliable Evidence To Rate" for Chronic fatigue syndrome (CFS) (Natural Medicines).
  • Also on file: Cat's Claw is rated "Insufficient Reliable Evidence To Rate" for Inflammatory bowel disease (IBD), Osteoarthritis, Rheumatoid arthritis (RA).

The evidence for cat's claw is limited. For the six conditions listed in our data — allergic rhinitis (hay fever), Alzheimer disease, asthma, osteoporosis, cancer, and chronic fatigue syndrome — we don't have enough reliable research to say whether it works.

That doesn't mean it doesn't; it means the studies either aren't there or aren't strong enough yet to make a confident call.

The evidence, ingredient by ingredient Cat'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.

Cat's claw is generally well tolerated in the short term for healthy adults, but how safe it is over months or years isn't well studied. In one clinical trial in cancer patients, some blood count changes occurred (anemia in 12%, low white blood cells and low platelets each in 2%), though it's unclear whether cat's claw or the disease caused them.

There are also several case reports linking cat's claw to kidney injury, particularly in people with lupus or a history of cancer. Headache, fatigue, insomnia, and nerve pain showed up in small percentages in that same trial.

Don't use cat's claw during pregnancy — it has a history of being used to end pregnancy, and we don't have safety data. Avoid it while breastfeeding too, since we don't know enough about what passes into milk or whether it's safe for a nursing infant.

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 — Cat's Claw.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs.
  • For scale: 963 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 your exact medications before starting if you take blood thinners or antiplatelet drugs (bleeding risk), blood pressure or calcium channel blocker medications, liver-metabolized drugs (CYP3A4 substrates like many statins and antibiotics), nirmatrelvir/ritonavir (Paxlovid), or immunosuppressants.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Samento is for people curious about cat's claw's traditional uses, but the science on whether it actually works for specific conditions isn't solid yet. If you take any blood pressure, heart, blood thinner, or immune medication, or any drug your liver metabolizes heavily, you need to check this with your pharmacist first — the interaction list is long.

Pregnant women and nursing mothers should skip it entirely.

Uncaria tomentosa Bark Extract6 drug types · 962 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, cat's claw may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Cat's claw contains rhynchophylline and isorhynchophylline. Animal research suggests that these alkaloids can inhibit platelet aggregation. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, taking cat's claw with antihypertensive drugs might increase the risk of hypotension.
Cat's claw contains rhynchophylline. In vitro and animal research suggests that rhynchophylline can lower blood pressure. This interaction has not been reported in humans.

Likelihood Probable Evidence D
Calcium Channel Blockers

Theoretically, taking cat's claw with calcium channel blockers might increase the risk of hypotension.
Cat's claw contains various alkaloids, including rhynchophylline, isorhynchophylline, corynoxeine, and isocorynoxiene. Animal research suggests that these alkaloids can lower blood pressure by acting as calcium channel blockers. This interaction has not been reported in humans.

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

Theoretically, cat's claw might increase or decrease the levels and effects of drugs metabolized by CYP3A4.
Cat's claw may affect the clearance of drugs metabolized by CYP3A4. In vitro research shows that cat's claw can inhibit CYP3A4 enzymes. In one case report, a patient taking cat's claw (at an unspecified dose) experienced increased serum levels of atazanavir, ritonavir, and saquinavir, all of which are CYP3A4 substrates. Levels returned to normal 15 days after discontinuation of the cat's claw supplement, suggesting inhibition of CYP3A4 by cat's claw. In contrast, animal research suggests that rhynchophylline, an alkaloid contained in cat's claw, induces CYP3A expression and accelerates the metabolism of nirmatrelvir, the active component in the nirmatrelvir/ritonavir combination product.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, cat's claw might interfere with immunosuppressive therapy.
In human and laboratory research, cat's claw has been shown to have immunostimulating activity. It stimulates phagocytosis and increases respiratory cellular activity and the mobility of leukocytes. Theoretically, this could interfere with the activity of immunosuppressant medications.

Likelihood Possible Evidence D
Nirmatrelvir/Ritonavir (Paxlovid)

Theoretically, cat's claw may decrease the levels of nirmatrelvir.
Cat's claw contains rhynchophylline. Animal research suggests that this alkaloid induces CYP3A expression, thereby accelerating the metabolism of nirmatrelvir, the active component in the nirmatrelvir/ritonavir combination product. This interaction has not been reported in humans.

Samento by NutraMedix: Common Questions

Does Samento by NutraMedix interact with any medications?
Yes. Based on its ingredients, Samento has a known interaction with 962 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Samento 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 cat's claw proven to work for anything?
Not yet, based on the data we hold. For the conditions cat's claw is marketed for — hay fever, Alzheimer's, asthma, osteoporosis, cancer, and chronic fatigue — we have insufficient reliable evidence to say whether it actually works. That doesn't rule out benefit, just that the research isn't strong enough to be sure.
What are the main side effects I should watch for?
In one trial, headache, fatigue, and insomnia each occurred in 4% of participants, and nerve pain in 8%. Blood count drops (anemia, low white cells, low platelets) also happened, though the patients had advanced cancer so it's hard to know what caused them. Several case reports link cat's claw to kidney injury, so be alert for changes in urine output or swelling.
Can I take this if I'm pregnant or breastfeeding?
No. Cat's claw has traditionally been used to end pregnancy, and we don't have safety data to contradict that concern. While breastfeeding, there's also not enough information on whether it's safe for your baby, so it's best to avoid it.
What exactly is in this supplement?
Samento contains just one active ingredient: cat's claw bark extract (Uncaria tomentosa). It's mixed with mineral water and ethanol to make it a liquid.
How long has cat's claw been used?
The product facts don't give us that history, but the safety notes mention its traditional use as an abortifacient — suggesting it's been used for a long time in certain cultures. Long traditional use doesn't automatically mean it's safe or proven, though.
