HelloPharmacist Scorecard of Boldo 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

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 extract in a dry form. Boldo is a South American herb traditionally used for digestive and kidney support, though the evidence for these uses is limited.

The liquid also contains glycerin and water as inactive ingredients to deliver the extract.

Does it work?

Insufficient 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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Liver, gallbladder, and digestive support.
  • We looked for evidence on: Gallbladder disease, indigestion, bloating, constipation.
  • The closest evidence on file: Boldo is rated "Insufficient Reliable Evidence To Rate" for Gallbladder disease (Natural Medicines).

We don't have solid evidence that boldo works for any of its traditional uses. The data we hold lists benign prostate enlargement, gallbladder disease, kidney stones, and joint pain—but all of them are rated as having insufficient reliable evidence.

That means the studies either aren't there or aren't strong enough to say whether boldo actually helps.

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 boldo is used in food amounts, it's generally well tolerated. But medicinal doses—like what's in a supplement—carry real risks.

The herb contains ascaridole, a liver toxin, and case reports show it can cause elevated liver enzymes, jaundice, nausea, vomiting, and abdominal pain. The safety notes advise short-term use at low doses only if you go that route.

Boldo is considered unsafe in pregnancy because it may stimulate the uterus. There isn't enough safety data to recommend it while breastfeeding, so it's best avoided then too.

Side effects, ingredient by ingredient 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?
  • 1 of the 1 matched ingredient can interact with medications — Boldo.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; lithium.
  • For scale: 483 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 you start Herbal Terra's Boldo Alcohol Free, double-check with your pharmacist if you take any liver-damaging medications, blood thinners (like warfarin or aspirin), lithium, or tacrolimus. All of these carry Moderate-severity interaction risks with boldo.

The bottom line

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

Boldo has a long traditional history, but the evidence for what it actually does is thin, and the liver and bleeding risks are real—especially if you're on any blood thinner, liver-affecting medication, lithium, or an immunosuppressant like tacrolimus. Talk to your pharmacist about your full medication list before trying this one, and don't use it long-term without close monitoring.

Ingredients driving the most interactions

Each ingredient & the kinds of drugs it affects

For each ingredient in Boldo Alcohol Free with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.

Boldo Leaf Extract, Dry5 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 Alcohol Free by Herbal Terra: Common Questions

Does Boldo Alcohol Free by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Boldo Alcohol Free 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 Alcohol Free 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 boldo safe to use while I'm pregnant or breastfeeding?
No. Boldo is considered unsafe in pregnancy because it may stimulate the uterus. There also isn't enough safety information to recommend it while breastfeeding, so it's best avoided then as well. Talk to your doctor or pharmacist if you're thinking about any herbal supplement during pregnancy or while nursing.
What are the common side effects I might notice?
When used in medicinal amounts, boldo most commonly causes abdominal pain, nausea, and vomiting. The bigger worry is liver damage—the herb contains ascaridole, a known liver toxin, and cases have reported elevated liver enzymes and jaundice with boldo use.
Does boldo actually work for the things it's supposed to help with?
We don't have strong evidence. Boldo is traditionally used for gallbladder disease, kidney stones, prostate issues, and joint pain, but all of those uses are rated as having insufficient reliable evidence to say whether the herb really helps.
Why is there such a high number of potential medication interactions?
The 466 medications reflect the broad categories boldo interacts with: any drug that can harm the liver, any blood thinner or antiplatelet medication, lithium, and tacrolimus. Because there are hundreds of drugs in each of those categories, the total is large. Your pharmacist can tell you whether your specific medications fall into any of these groups.
Is boldo safe if I have liver problems?
No. Boldo contains ascaridole, a liver toxin, and the safety notes specifically caution against its use. Case reports show it can cause elevated liver enzymes and jaundice. If you have any liver disease or take any medication that affects the liver, avoid this product and talk to your pharmacist.
How long is it safe to use boldo?
The safety data advises short-term use in low doses only—not long-term. Because of the liver toxin it contains, sustained use carries real risk. If you're considering boldo, keep it brief and talk to your pharmacist about monitoring.
