HelloPharmacist Scorecard of Uterus Support Sugar Free Alcohol Free by Herbal Terra

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 11, 2026

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 3 active ingredients.
  • “Proprietary Extract Blend” is a proprietary blend — the label gives one combined amount (1,156 mg) without saying how much of each component you get.

This liquid contains three active ingredients. Bromelain is an enzyme from pineapple that may help reduce swelling.

Cat's claw inner bark extract comes from a tropical vine and has been used in traditional medicine. Vitex berry extract, also called chasteberry, is commonly used in women's health formulas.

The product also contains glycerin and water as inactive ingredients.

Does it work?

Couldn't assess
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 assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Uterus support.
  • We looked for evidence on: Uterine health, Menstrual support, Reproductive health, Pelvic support.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence on whether these ingredients work for uterine or women's health support isn't established in our data. Bromelain, cat's claw, and vitex berry have been studied for various conditions — allergies, chronic fatigue, bone health, cancer, and others — but none have sufficient reliable evidence to confirm effectiveness for those uses.

We can't speak to how they may help with uterine support specifically, since that isn't in our records.

The evidence, ingredient by ingredient Bromelain 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 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.

Bromelain is generally well tolerated short-term when taken by mouth, though long-term safety data is limited. Common side effects include diarrhea, gas, stomach upset, and headache.

In rare cases, allergic reactions can occur. Cat's claw is also generally well tolerated short-term in healthy adults, but long-term safety is not well studied.

In one clinical trial, some patients experienced headache, fatigue, insomnia, and nerve pain, though that study included only advanced cancer patients with no placebo comparison, so it's unclear if these effects were from the supplement itself. Case reports have linked cat's claw to kidney injury in a few patients.

Bromelain is not recommended during pregnancy due to insufficient safety data. Safety while breastfeeding is unknown, so it's best avoided.

Cat's claw should also be avoided during pregnancy because of its traditional use as an abortifacient combined with lack of safety evidence, and it should be avoided while breastfeeding due to insufficient safety information. There is no pregnancy or breastfeeding data on file for vitex berry extract.

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 — Cat's Claw, Bromelain.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs.
  • For scale: 981 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 starting this product, check whether you take blood thinners or antiplatelet drugs (like warfarin, aspirin, or clopidogrel), blood pressure medications (antihypertensives or calcium channel blockers), drugs metabolized by the liver enzyme CYP3A4 (a very large group including some statins, certain heart drugs, and some psychiatric medications), immunosuppressants, tetracycline antibiotics, or nirmatrelvir/ritonavir (Paxlovid). These are all documented as moderate-severity interactions with ingredients in this product.

Cat's Claw Inner 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.

Bromelain, Powder2 drug types · 141 drugs

Anticoagulant/Antiplatelet Drugs

Bromelain may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
There is one case report of a patient experiencing minor bruising while taking bromelain with naproxen. Bromelain is thought to have antiplatelet activity. Whether this interaction is of concern with topical bromelain is unclear. Interference with coagulation of burn wounds has been reported in a patient receiving bromelain-based enzymatic debridement. However, observational research has found that topical bromelain debridement is not associated with increases or decreases in laboratory markers of coagulation when compared with surgical debridement.

Likelihood Possible Evidence D
Tetracycline Antibiotics

Theoretically, bromelain might increase levels of tetracycline antibiotics.
Laboratory research suggests that bromelain might increase the absorption of tetracycline antibiotics. However, a study in healthy adults reported no difference in tetracycline plasma levels when a 500 mg dose was taken with or without bromelain 80 mg.

Uterus Support Sugar Free Alcohol Free by Herbal Terra: Common Questions

Does Uterus Support Sugar Free Alcohol Free by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Uterus Support Sugar Free Alcohol Free has a known interaction with 980 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Uterus Support Sugar Free Alcohol Free 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.
What is bromelain, and what's it supposed to do?
Bromelain is an enzyme derived from pineapple. It's included in supplements for various reasons, but the evidence on whether it actually works for conditions like allergies, burns, or chronic venous insufficiency isn't strong enough yet to say it's effective.
Can I take this while I'm pregnant or breastfeeding?
No. Bromelain should be avoided during pregnancy due to lack of safety data, and safety while breastfeeding is unknown. Cat's claw should also be avoided during pregnancy — it has a history of traditional use as an abortifacient — and should not be used while breastfeeding. Talk with your OB or pharmacist about alternatives.
What side effects might bromelain cause?
The most common ones are diarrhea, gas, stomach upset, and headache. In rare cases, allergic reactions including asthma, throat itching, and eye irritation can occur, especially if you inhale the powder or if you have a pineapple allergy.
Is there any long-term safety data on cat's claw?
No. Cat's claw is generally well tolerated in the short term, but we don't have good long-term safety studies. Case reports have linked it to kidney injury in a handful of patients, so it's worth being cautious if you have kidney disease or a history of kidney problems.
Why does this product interact with so many medications?
Cat's claw can affect how your liver breaks down many common drugs — it may speed up or slow down the process — making their levels in your bloodstream unpredictable. Bromelain may increase bleeding risk and affect antibiotic absorption. These effects are the reason we need you to check your specific medications before starting.
What is vitex (chasteberry), and did you check it for interactions?
Vitex is an extract from chasteberry, traditionally used in women's health supplements. We don't hold interaction data for this particular ingredient, so we couldn't check it. If you're concerned about how it might interact with your medications, ask your pharmacist.
