HelloPharmacist Scorecard of Goldenseal Root 125 mg by Swanson
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: Goldenseal Root Extract at 125 mg per capsule. The inactive ingredients are rice flour, gelatin, maltodextrin, and calcium palmitate—standard capsule fillers and binders.
Does it work?
Couldn't assess
The evidence we hold doesn't support goldenseal for the uses listed here. It's marked possibly ineffective for passing urine drug tests, and we have insufficient reliable evidence to rate it for acne, hay fever, anorexia nervosa, or chronic fatigue syndrome.
If you're considering it for another reason, your doctor or pharmacist can discuss what the research actually shows.
How safe is it?
Well-documented data
Goldenseal is generally well tolerated in short-term use by healthy adults, but human safety data are limited and we don't have reliable information on safety beyond a single dose. Berberine, its main active compound, can cause digestive upset—abdominal pain, diarrhea or constipation, nausea, vomiting, flatulence, bitter taste, and headache have been reported with berberine supplements.
Do not take goldenseal during pregnancy; the safety data advise against it because berberine may harm the fetus and could trigger contractions. Also avoid it while breastfeeding—berberine can pass into breast milk and may harm the infant.
If you're pregnant, planning to become pregnant, or nursing, talk with your doctor or pharmacist before considering this product.
Meds to double-check
Moderate interaction found
Before taking this product, check with your doctor or pharmacist if you're on any of these: drugs broken down by CYP2D6 enzymes (a major liver pathway—includes many antidepressants, some pain medications, and others), blood pressure medications, diabetes drugs, blood thinners (anticoagulants) or drugs that affect bleeding, sedatives or CNS depressants, or drugs metabolized by CYP3A4 or CYP2C9 enzymes. The CYP2D6 and CYP3A4 effects have clinical research; the others are theoretical but still worth checking.
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 Root may be worth considering only if you have a specific reason for it and your own doctor or pharmacist has confirmed it won't interfere with your medications—because the interaction list is long and affects how your liver processes many common drugs. If you take any prescription or over-the-counter medication, blood pressure drugs, diabetes medications, or sleep aids, you should check your exact drugs against the list on this page before starting.
Pregnant people and those breastfeeding should not take it. Talk with your doctor or pharmacist about whether it's right for you.

Goldenseal Root 125 mg by Swanson Drug Interactions
HelloPharmacist Interaction Report
Swanson's Goldenseal Root Extract does interact with medications—through its berberine and other alkaloid content, it affects how your body handles and responds to several drug types.
The most serious documented effect is that it can inhibit CYP2D6 enzymes (a major liver metabolic pathway), potentially raising levels of drugs broken down that way and causing them to build up in your system.
Read the full breakdown — every affected drug type, severity by severity
Beyond that, goldenseal may increase blood levels of drugs metabolized by CYP3A4 and CYP2C9 enzymes, theoretically making those medications stronger than intended. It can also increase sedation if you're taking CNS depressants (sedatives, sleep aids, some pain medications), raise the risk of low blood pressure with blood pressure drugs, raise bleeding risk with blood thinners (anticoagulants) or antiplatelet drugs, and raise the risk of low blood sugar (hypoglycemia) if you take diabetes medications.
Evidence also suggests conflicting effects on P-glycoprotein substrates—a class of drugs moved in and out of cells by a specific transport protein.
Almost all of these effects are animal-study or lab-based findings not yet confirmed in humans, but the CYP2D6 and CYP3A4 effects have clinical research behind them. Altogether, these interactions span 1,238 individual medications.

For each ingredient in Goldenseal Root 125 mg 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 Root 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.
