HelloPharmacist Scorecard of Boldo Non-Alcohol by Hawaii Pharm

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

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 1 active ingredient.

This product contains one active ingredient: wild harvested boldo extract. Boldo is a plant whose leaf and oil have been used traditionally for gallbladder and digestive support, though reliable evidence for these uses is limited.

The liquid also includes vegetable palm glycerin and artesian Hawaiian water as inactive ingredients—these are the base that holds and delivers 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 evidence we hold doesn't establish that boldo is effective for any of its marketed uses. We have insufficient reliable evidence to rate it for benign prostatic hyperplasia (enlarged prostate), gallbladder disease, kidney stones, or joint pain.

That doesn't mean it doesn't work—it means the supporting research isn't solid enough for us to say either way.

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.

Boldo is generally well tolerated at food-level amounts, but medicinal doses—the kind in a supplement—can cause real harm. The most serious concern is liver injury.

Ascaridole, a compound in boldo leaf, is a known liver toxin, and several case reports document elevated liver enzymes and jaundice in people taking boldo supplements. At lower medicinal doses used short-term, the risk may be lower, but it's still a genuine concern.

Common side effects from oral use include abdominal pain, nausea, and vomiting. We don't have enough safety data to recommend boldo during pregnancy—in fact, it may stimulate the uterus, so it's considered unsafe then.

We also don't have enough information to call it safe while breastfeeding, so it's best avoided.

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 starting this product, check with your doctor or pharmacist if you take any liver-stressing drugs, blood thinners (anticoagulants or antiplatelet drugs like warfarin or aspirin), lithium, or tacrolimus. These interactions are all rated Moderate severity.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Boldo extract isn't a proven remedy for the conditions it's marketed for, and it carries real risks—liver injury, bleeding if you're on blood thinners, and interactions with transplant and mood-stabilizing drugs. If you're considering it, talk with your doctor or pharmacist first, especially if you take any medications or have liver concerns.

wild harvested Boldo 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 Non-Alcohol by Hawaii Pharm: Common Questions

Does Boldo Non-Alcohol by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Boldo Non-Alcohol 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 Non-Alcohol 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 during pregnancy or while breastfeeding?
Boldo is considered unsafe during pregnancy because it may stimulate the uterus. There isn't enough safety information to recommend it while breastfeeding either. Talk with your doctor before using it if you're pregnant, planning to become pregnant, or nursing.
What are the most common side effects?
The most common side effects from taking boldo orally are abdominal pain, nausea, and vomiting. The most serious risk is liver injury from ascaridole, the liver toxin in boldo leaf; this is rare but documented in case reports.
Can I take boldo if I'm on warfarin or another blood thinner?
No, not without checking with your doctor first. Boldo may increase bleeding risk when combined with blood thinners. A case report documented an increase in bleeding levels in someone taking boldo with warfarin.
Does boldo actually work for gallbladder or kidney problems?
We don't have reliable evidence that boldo works for gallbladder disease, kidney stones, or the other conditions it's marketed for. The research backing these uses isn't solid enough to say it's effective.
Why is liver injury a concern with boldo?
Boldo leaf contains ascaridole, a known liver toxin. Several case reports show that people taking boldo supplements developed elevated liver enzymes and jaundice, signs of liver damage. If you take it, your liver is at risk.
Is this non-alcohol version safer than other boldo products?
The non-alcohol form removes the alcohol solvent, but the active ingredient—boldo extract and its liver-toxic compound ascaridole—is the same. The form doesn't eliminate the safety concerns tied to boldo itself.
