HelloPharmacist Scorecard of Coptis by Herb Pharm
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: coptis rhizome extract, also known as goldthread. It's a liquid extract in a base of cane alcohol and distilled water.
Does it work?
Couldn't assess
We don't have effectiveness data on file for coptis in our holdings. If you're considering this herb for a specific use, talk with your pharmacist or doctor about what the evidence actually shows.
How safe is it?
Some data gaps
Human safety data for goldthread are limited, and the quality of goldthread products can vary. Short-term use by adults may be tolerated, but we don't have robust long-term safety information.
Goldthread should be avoided during pregnancy and while breastfeeding — berberine, its active compound, may harm a fetus or newborn and can pass into breast milk.
Meds to double-check
Moderate interaction found
Before you take this, double-check any drug metabolized by CYP3A4 — that's a large group that includes lovastatin and many others — and cyclosporine if you're on it. The interaction is moderate for both, meaning the levels of your medication could rise.
Run your specific prescriptions through the checker on this page.
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.
Coptis is a single-herb extract that may slow how your liver processes certain medications, especially those handled by the CYP3A4 enzyme and cyclosporine. If you take any prescription drugs, check them against this product's interactions before starting.
Pregnancy and breastfeeding are not appropriate times to use it.

Coptis by Herb Pharm Drug Interactions
HelloPharmacist Interaction Report
Herb Pharm's Coptis is a single-ingredient liquid extract of goldthread rhizome that does interact with medications.
The main concern is with drugs broken down by a liver enzyme called CYP3A4 (cytochrome P450 3A4). Berberine, the active compound in goldthread, may slow how your liver clears these drugs, which could raise their levels in your blood — though this interaction hasn't yet been seen in humans, only in preliminary lab work.
Watch especially for any increase in side effects if you're on a CYP3A4 substrate; some examples include lovastatin and many others.
Read the full breakdown — every affected drug type, severity by severity
There's also a documented moderate interaction with cyclosporine (Neoral, Sandimmune), an immunosuppressant drug. Berberine can reduce how quickly your body breaks down cyclosporine and raise the amount in your bloodstream.
Altogether, these interactions span 644 individual medications. Because the data on goldthread in humans is thin, it's important to run your exact medications through the interaction checker below before you start.

For each ingredient in Coptis 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.
Coptis rhizome extract
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.
