HelloPharmacist Scorecard of Goldenseal Max-V by Douglas Laboratories
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
Goldenseal Max-V contains 2 active ingredients—goldenseal herbal extract and goldenseal itself—both sourced from the same plant. These deliver goldenseal's active alkaloids, including berberine, which accounts for the supplement's therapeutic effects and interaction potential.
The capsule also contains inactive ingredients (cellulose, silica, and vegetable stearate) that serve as filler and binder.
Does it work?
Couldn't assess
The evidence for goldenseal in the conditions listed is limited. We have insufficient reliable evidence to rate it for acne, allergic rhinitis (hay fever), anorexia nervosa, or chronic fatigue syndrome.
For clearing urine drug tests, it's been rated possibly ineffective.
How safe is it?
Well-documented data
Goldenseal is generally well tolerated when used for short periods in healthy adults, though human safety data are limited. The ingredient berberine—goldenseal's main active compound—can cause stomach upset, including abdominal distension, pain, constipation, diarrhea, flatulence, bitter taste, nausea, vomiting, and headache.
Most of these effects come from theoretical extrapolation based on berberine research rather than reported cases with the supplement itself. The safety notes advise against use during pregnancy—berberine may harm the fetus and could trigger uterine contractions—and during breastfeeding because berberine may pass into breast milk and potentially harm the infant.
Meds to double-check
Moderate interaction found
Before taking Goldenseal Max-V, check with your doctor or pharmacist if you use blood thinners or antiplatelet drugs (moderate interaction risk), CNS depressants like benzodiazepines or sedatives (moderate risk), blood pressure medications (moderate risk), diabetes drugs (moderate risk), or any medication processed through your liver's CYP2D6, CYP2C9, or CYP3A4 enzymes (moderate risk), or drugs that use P-glycoprotein for transport (moderate risk).
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.
Goldenseal Max-V is a straight herbal supplement that can interact with quite a few medication classes. If you take anything for blood pressure, blood thinning, sleep, diabetes, or liver metabolism of drugs, you'll want to check with your doctor or pharmacist before starting this.
It's not for use in pregnancy or while breastfeeding. Talk it over with your own healthcare provider to see if it's right for you.

Goldenseal Max-V by Douglas Laboratories Drug Interactions
HelloPharmacist Interaction Report
Goldenseal Max-V by Douglas Laboratories does interact with medications.
Its goldenseal content can affect how your body handles several drug classes through enzyme interactions and blood pressure effects, with the most serious being a potential increase in bleeding risk when combined with blood thinners or antiplatelet drugs (anticoagulants or drugs that prevent clotting).
Read the full breakdown — every affected drug type, severity by severity
The product's goldenseal may increase blood levels of drugs processed by your liver's CYP2D6, CYP2C9, and CYP3A4 enzymes—meaning these medications could build up in your system and become stronger than intended. It can also theoretically raise or lower levels of drugs that depend on a cellular transport system called P-glycoprotein, though the evidence on P-gp is mixed.
Additionally, goldenseal might boost the sedative effects of CNS depressants (drugs that slow your brain activity, like sleep aids or benzodiazepines) and increase the blood-pressure-lowering effect of antihypertensive drugs, raising the risk of dizziness or fainting. It may also increase the risk of low blood sugar (hypoglycemia) if you take diabetes medications.
All of these concerns stem from goldenseal's active compounds, particularly berberine. Altogether, these interactions span 1,238 individual medications.

For each ingredient in Goldenseal Max-V 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.
Goldenseal Herbal Extract
Anticoagulant/Antiplatelet Drugs
Theoretically, goldenseal might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Goldenseal contains berberine. In vitro and animal research shows that berberine can inhibit platelet aggregation. However, this effect has not been reported in humans.
Antidiabetes Drugs
Theoretically, goldenseal might increase the risk of hypoglycemia when used with antidiabetes drugs.
Goldenseal contains berberine. Clinical research shows that berberine can lower blood glucose levels. However, this effect has not been reported with goldenseal.
Antihypertensive Drugs
Theoretically, goldenseal might increase the risk of hypotension when taken with antihypertensive drugs.
Goldenseal contains berberine. Animal research shows that berberine can have hypotensive effects. Also, an analysis of clinical research shows that taking berberine in combination with amlodipine can lower systolic and diastolic blood pressure when compared with amlodipine alone. However, this effect has not been reported with goldenseal.
Cns Depressants
Theoretically, goldenseal might increase the sedative effects of CNS depressants.
Goldenseal contains berberine. Animal research shows that berberine can have sedative effects. However, this effect has not been reported in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, goldenseal might increase serum levels of drugs metabolized by CYP2C9.
In vitro research shows that goldenseal root extract can modestly inhibit CYP2C9. This effect may be due to its alkaloid constituents, hydrastine and berberine. However, this effect has not been reported in humans.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Goldenseal might increase serum levels of drugs metabolized by CYP2D6.
Clinical and in vitro research shows that goldenseal can significantly inhibit CYP2D6 enzymes, potentially increasing levels of drugs metabolized by CYP2D6.
Cytochrome P450 2E1 (Cyp2E1) Substrates
Theoretically, goldenseal might increase serum levels of drugs metabolized by CYP2E1.
In vitro research shows that goldenseal root extract can inhibit the activity of CYP2E1. However, this effect has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Goldenseal might increase serum levels of drugs metabolized by CYP3A4.
Most clinical and in vitro research shows that goldenseal inhibits CYP3A4 enzyme activity and increases serum levels of CYP3A4 substrates, such as midazolam. However, in one small clinical study, goldenseal did not affect the levels of indinavir, a CYP3A4 substrate, in healthy volunteers. This is likely due to the fact that indinavir has a high oral bioavailability, making it an inadequate probe for CYP3A4 interactions and/or that it is primarily metabolized by hepatic CYP3A, while goldenseal has more potential to inhibit intestinal CYP3A enzyme activity. Both goldenseal extract and its isolated constituents berberine and hydrastine inhibit CYP3A, with hydrastine possibly having more inhibitory potential than berberine.
Dextromethorphan (Robitussin Dm, Others)
Theoretically, goldenseal might increase serum levels of dextromethorphan.
Goldenseal contains berberine. A small clinical study shows that berberine can inhibit cytochrome P450 2D6 (CYP2D6) activity and reduce the metabolism of dextromethorphan.
Digoxin (Lanoxin)
Goldenseal might increase serum levels of digoxin, although this effect is unlikely to be clinically significant.
Clinical research shows that goldenseal modestly increases digoxin peak levels by about 14% in healthy volunteers. However, goldenseal does not seem to affect other pharmacokinetic parameters such as area under the curve (AUC). This suggests that goldenseal does not cause a clinically significant interaction with digoxin. Digoxin is a P-glycoprotein substrate. Some evidence suggests that goldenseal constituents might affect P-glycoprotein; however, it is unclear whether these constituents inhibit or induce P-glycoprotein.
Losartan (Cozaar)
Theoretically, goldenseal might decrease the conversion of losartan to its active form.
Goldenseal contains berberine. A small clinical study shows that berberine inhibits cytochrome P450 2C9 (CYP2C9) activity and reduces the metabolism of losartan. However, this effect has not been reported with goldenseal.
Metformin (Glucophage)
Theoretically, goldenseal might reduce blood levels of metformin.
In vitro research shows that goldenseal extract decreases the bioavailability of metformin, likely by interfering with transport, intestinal permeability, or other processes involved in metformin absorption. It is unclear which, if any, of metformin's transporters are inhibited by goldenseal. Goldenseal does not appear to alter the clearance or half-life of metformin.
P-Glycoprotein Substrates
Theoretically, goldenseal might increase or decrease serum levels of P-glycoprotein (P-gp) substrates.
There is conflicting evidence about the effect of goldenseal on P-gp. In vitro research suggests that berberine, a constituent of goldenseal, modestly inhibits P-gp efflux. Other evidence suggests that berberine induces P-gp. In healthy volunteers, goldenseal modestly increases peak levels of the P-gp substrate digoxin by about 14%. However, it does not seem to affect other pharmacokinetic parameters such as area under the curve (AUC). This suggests that goldenseal is not a potent inhibitor of P-gp-mediated drug efflux. Until more is known, goldenseal should be used cautiously with P-gp substrates.
Pentobarbital (Nembutal)
Theoretically, goldenseal might increase the sedative effects of pentobarbital.
Animal research shows that berberine, a constituent of goldenseal, can prolong pentobarbital-induced sleeping time. However, this effect has not been reported with goldenseal.
Tacrolimus (Prograf)
Theoretically, goldenseal might increase serum levels of tacrolimus.
Goldenseal contains berberine. In a 16-year-old patient with idiopathic nephrotic syndrome who was being treated with tacrolimus 6.5 mg twice daily, intake of berberine 200 mg three times daily increased the blood concentration of tacrolimus from 8 to 22 ng/mL. Following a reduction of tacrolimus dosing to 3 mg daily, blood levels of tacrolimus decreased to 12 ng/mL.
Oseltamivir (Tamiflu)
Theoretically, goldenseal might reduce the therapeutic effects of oseltamivir by decreasing its conversion to its active form.
In vitro evidence suggests that goldenseal reduces the formation of the active compound from the prodrug oseltamivir. The mechanism of action and clinical relevance is unclear.
