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.
What’s inside
Full disclosure
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
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.
How safe is it?
Well-documented data
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.
Meds to double-check
Moderate interaction found
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.

Boldo Alcohol Free by Herbal Terra Drug Interactions
HelloPharmacist Interaction Report
Herbal Terra's Boldo Alcohol Free contains boldo leaf extract, which carries Moderate-severity interactions with several medication types.
The most serious concern is with drugs that can harm the liver (hepatotoxic drugs): boldo itself contains ascaridole, a known liver toxin, and case reports document elevated liver enzymes and jaundice in people taking boldo products. Adding boldo to an already liver-damaging medication could worsen that risk.
Read the full breakdown — every affected drug type, severity by severity
Boldo also interacts with blood thinners and antiplatelet drugs (like warfarin and aspirin). The herb has compounds that thin the blood on their own, and one case report documented increased bleeding risk when boldo was combined with warfarin.
Additionally, if you take lithium for mood disorders, boldo's diuretic effect might raise lithium levels in your blood, potentially requiring a dose adjustment. Tacrolimus (an immunosuppressant used after transplant) may also drop to unsafe levels when combined with boldo.
Altogether, these interactions span 466 individual medications. Run your exact prescriptions through the checker below before you start this product.

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, Dry
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.
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.
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.
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.
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.
