HelloPharmacist Scorecard of Boldo Leaf Mint 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 16, 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: boldo leaf glycerite liquid extract. Boldo is a South American plant traditionally used for digestive and gallbladder support, though the evidence for these uses is not yet established in our data.

The liquid also contains glycerin and mint flavor as inactive ingredients — these are excipients that help deliver and flavour the extract.

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

This is a single-ingredient Boldo product and its label doesn't state a use — see Boldo's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The data we hold shows insufficient reliable evidence to rate boldo leaf for benign prostatic hyperplasia (enlarged prostate), gallbladder disease, kidney stones, or joint pain. That means the evidence isn't clear enough yet to say whether it works for these purposes.

If you're considering this product for any of these uses, talk with your doctor or pharmacist about whether it's right for you.

The evidence, ingredient by ingredient 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 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.

When used in food-level amounts, boldo is generally well tolerated. At medicinal doses — like those in this liquid extract — it carries real safety concerns.

The most important one is liver damage: boldo contains ascaridole, a liver toxin, and cases of elevated liver enzymes and jaundice have been reported. Common side effects at higher doses include abdominal pain, nausea, and vomiting.

Boldo is considered unsafe in pregnancy because it may stimulate the uterus. There isn't enough safety information to use it while breastfeeding.

If you're pregnant, planning pregnancy, or breastfeeding, talk with your doctor or pharmacist before using this product.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Boldo leaf has a long traditional history but carries real drug interaction and safety risks at medicinal doses — especially for your liver, blood thinning, and transplant medications. If you take any prescription medications, especially blood thinners, lithium, tacrolimus, or drugs that stress the liver, check them against our medication tool before starting.

Boldo Leaf Glycerite Liquid Extract5 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.

Boldo Leaf Mint Flavor by TerraVita: Common Questions

Does Boldo Leaf Mint Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Boldo Leaf Mint Flavor has a known interaction with 482 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Boldo Leaf Mint 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 this if I'm on blood thinners like warfarin?
No — boldo interacts with blood thinners and may increase your bleeding risk. A case has been reported where boldo combined with another supplement raised bleeding markers in someone on warfarin. Talk to your doctor or pharmacist before using this product if you take any blood thinners.
Is boldo safe for my liver?
Not at medicinal doses. Boldo contains ascaridole, a known liver toxin, and multiple cases of liver damage — including elevated liver enzymes and jaundice — have been reported with medicinal use. If you have any liver disease or concerns, check with your doctor or pharmacist before using this.
Can I take this while pregnant or breastfeeding?
No. Boldo is considered unsafe in pregnancy because it may stimulate the uterus, and there isn't enough safety data to use it while breastfeeding. Talk with your doctor or pharmacist if you're in either situation.
What does boldo actually do — does it work?
Boldo is traditionally used for digestive and gallbladder support, but we don't have reliable evidence yet to say it works for gallbladder disease, kidney stones, enlarged prostate, or joint pain. If you're considering it for any of these, ask your doctor or pharmacist whether it's appropriate for you.
What are the side effects of this product?
At food-level amounts boldo is generally well tolerated, but at medicinal doses like those in this extract, abdominal pain, nausea, and vomiting are common. Liver damage is the most serious risk. Stop use and contact your doctor if you develop yellowing of the skin or eyes, dark urine, or right-side abdominal pain.
If I take lithium, can I use this?
No — boldo may reduce how quickly your body clears lithium, raising its levels to unsafe ranges. Lithium has a narrow safety window, so talk with your doctor or pharmacist before using any new supplements.
