HelloPharmacist Scorecard of Goldenthread Root Powder by TerraVita Premium Collection
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 powder contains one active ingredient: goldenthread (the whole root, powdered form). Goldenthread is a plant used in traditional herbal medicine; its active compound is berberine.
There are no other ingredients listed.
Does it work?
Couldn't assess
The product facts we have don't include effectiveness ratings for goldenthread. We can't tell you from our data whether it works for any particular condition.
How safe is it?
Some data gaps
Human safety data for goldenthread are limited, and quality can vary between products, so it's generally considered okay for short-term use by some adults — but that's with caution and under guidance. The bigger concern is pregnancy and breastfeeding: goldthread should be avoided during pregnancy because berberine may harm the fetus, and it should be avoided while breastfeeding because berberine can pass into breast milk and may harm the infant.
Meds to double-check
Moderate interaction found
Check your medications against this product if you take cyclosporine (an immunosuppressant) — berberine can raise its levels. You should also double-check any drug your pharmacist or doctor says is metabolized by the CYP3A4 liver enzyme, as berberine may cause it to build up in your system.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.
Goldenthread Root Powder could be an option if you're looking for a traditional herbal remedy and aren't pregnant, breastfeeding, or taking cyclosporine or medications that rely on CYP3A4 for breakdown. If you do take any of those medications, check with your doctor or pharmacist before starting.
Quality and safety data are limited, so talk it over with your own healthcare provider to see if it fits your situation.

Goldenthread, Powder monograph & interactionsGoldenthread Root Powder by TerraVita Premium Collection Drug Interactions
HelloPharmacist Interaction Report
Goldenthread Root Powder by TerraVita Premium Collection contains berberine, a compound that can interact with medications.
The most serious concern is with cyclosporine (an immunosuppressant used after organ transplant), where berberine may slow how your body clears the drug and raise its levels in your blood — a Moderate-severity interaction. There's also preliminary evidence that berberine might inhibit a major liver enzyme called CYP3A4, which could raise levels of drugs metabolized through that pathway.
Read the full breakdown — every affected drug type, severity by severity
Berberine may affect a large number of medications that depend on CYP3A4 for breakdown — including statins (cholesterol drugs), some blood pressure medications, and others. The concern here is Moderate severity, though the interaction hasn't yet been documented in actual patients.
Altogether, these interactions span 644 individual medications.
Before you start goldthread, run your current medications through the interaction checker below. If you take cyclosporine or any statin, blood pressure drug, or other medication your doctor or pharmacist says uses CYP3A4 for metabolism, clear this product with them first.

For each ingredient in Goldenthread Root Powder 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.
Goldenthread, Powder
Cyclosporine (Neoral, Sandimmune)
Berberine, a constituent of goldthread, can reduce metabolism of cyclosporine and increase serum levels. It might inhibit cytochrome P450 3A4 (CYP3A4), which metabolizes cyclosporine.
Cytochrome P450 3A4 (Cyp3A4) Substrates
There's very preliminary evidence that berberine, a constituent of goldthread, might inhibit cytochrome P450 3A4 (CYP3A4) enzyme. So far, this interaction has not been reported in humans. However, watch for an increase in the levels of drugs metabolized by CYP3A4 in patients taking goldthread. Some drugs metabolized by CYP3A4 include lovastatin (Mevacor), clarithromycin (Biaxin), indinavir (Crixivan), sildenafil (Viagra), triazolam (Halcion), and numerous others. Use goldthread cautiously or avoid in patients taking these drugs.
