HelloPharmacist Scorecard of Boldo and Barberry 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
Low disclosure
This liquid contains two active botanical extracts. Boldo leaf extract is the ingredient with documented effects on liver function and blood clotting.
Barberry root bark extract is also included, though we don't have interaction or effectiveness data on file for it. The product carries inactive ingredients — alcohol, water, and glycerin — that help dissolve and preserve the extracts.
Does it work?
Couldn't assess
The evidence we hold on boldo doesn't establish that it works for any of the conditions it's marketed for. The data rates effectiveness as insufficient for benign prostatic hyperplasia, gallbladder disease, kidney stones, and joint pain.
We have no effectiveness data on barberry root bark extract.
How safe is it?
Well-documented data
Boldo is generally well tolerated in small amounts, such as in food, but medicinal doses can cause significant problems. The most common side effects are abdominal pain, nausea, and vomiting.
The serious concern is liver injury — boldo contains ascaridole, a liver toxin, and case reports document elevated liver enzymes and jaundice in people taking it. Boldo is considered unsafe during pregnancy because it may stimulate the uterus.
There isn't enough safety information to recommend it while breastfeeding. If you're pregnant, planning pregnancy, or breastfeeding, talk with your pharmacist or doctor before taking this product.
Meds to double-check
Moderate interaction found
Double-check this product before taking it if you use any hepatotoxic drugs (liver-stressing medications), blood thinners or antiplatelet drugs like warfarin, lithium, or tacrolimus. All of these have documented moderate interactions with boldo.
If you're unsure whether your medication falls into one of these categories, use the checker on this page with your specific drugs.
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.
This product is for people interested in herbal remedies who don't take blood thinners, lithium, tacrolimus, or liver-stressing medications. If you take any prescription drugs, especially for the heart, brain, or liver, check them first — the interaction list is substantial.
Talk to your pharmacist before you start, and stop and contact your doctor right away if you develop nausea, vomiting, abdominal pain, or yellowing of the skin or eyes.

Boldo and Barberry by Herbal Terra Drug Interactions
HelloPharmacist Interaction Report
Herbal Terra's Boldo and Barberry contains boldo leaf extract, which has documented moderate-severity interactions with several medication types.
The most serious concern is with hepatotoxic drugs (medications that can stress the liver) — boldo itself contains ascaridole, a known liver toxin, and combining it with drugs that already burden your liver could increase the risk of liver injury. There are case reports of people taking boldo developing elevated liver enzymes and jaundice.
Read the full breakdown — every affected drug type, severity by severity
Boldo also interacts moderately with blood thinners and antiplatelet drugs like warfarin (Coumadin) because boldo appears to have mild blood-thinning properties of its own; one case report documented increased bleeding risk when boldo was combined with warfarin. It may also raise lithium levels by reducing how your kidneys clear the drug, potentially requiring a dose adjustment.
Additionally, boldo may lower tacrolimus levels in people taking it for transplant protection, raising the risk of rejection.
We cannot check barberry root bark extract — we hold no interaction data for it. Altogether, these interactions span 466 individual medications.
Before you start, run your exact medications through the checker below, especially if you take any blood thinners, lithium, tacrolimus, or drugs that affect your liver.

For each ingredient in Boldo and Barberry with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Barberry Root Bark Extract, Dry
Anticholinergic Drugs
Theoretically, taking European barberry with anticholinergic drugs might cause additive effects.
In vitro evidence suggests that European barberry might have anticholinergic properties.
Anticoagulant/Antiplatelet Drugs
Theoretically, European barberry may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal evidence suggest that berberine, a constituent of European barberry, might inhibit platelet aggregation. Theoretically, European barberry might have a similar effect.
Antidiabetes Drugs
Theoretically, taking European barberry with antidiabetes drugs might increase the risk of hypoglycemia.
Preliminary clinical evidence suggests that European barberry juice reduces fasting glucose levels in patients with type 2 diabetes who are also taking antidiabetes drugs. Additionally, some animal studies show that berberine, a constituent of European barberry, has antiglycemic potential. Monitor blood glucose levels closely.
Antihypertensive Drugs
Theoretically, taking European barberry with antihypertensive drugs might increase the risk of hypotension.
Animal and human research suggests that European barberry extracts can have hypotensive effects.
Cholinergic Drugs
Theoretically, taking European barberry with cholinergic drugs might decrease the effects of cholinergic drugs.
In vitro evidence suggests that European barberry might have anticholinergic properties.
Cns Depressants
Theoretically, concomitant use with drugs that have sedative properties may cause additive effects.
Animal research suggests that berberine, a constituent of European barberry, might have sedative effects. Theoretically, European barberry might have a similar effect.
Cyclosporine (Neoral, Sandimmune)
Theoretically, concomitant use with cyclosporine may cause additive effects.
Berberine, a constituent of European barberry, can reduce the metabolism and increase serum levels of cyclosporine. This effect is attributed to the ability of berberine to inhibit cytochrome P450 3A4 (CYP3A4), which metabolizes cyclosporine. Theoretically, European barberry might have a similar effect.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, European barberry might increase the levels and clinical effects of CYP3A4 substrates.
There is very preliminary evidence suggesting that berberine, a constituent of European barberry, might inhibit the CYP3A4 enzyme. Theoretically, European barberry might have a similar effect.
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.
