Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Interaction report

European Mandrake and Interferon Alfa-2b

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Interferon Alfa-2b and European Mandrake in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Interferon Alfa-2b

Interactions in our licensed database are recorded against drug classes, not just single drug names. Interferon Alfa-2b is filed under 2 classifications — photosensitizing drugs, hepatotoxic drugs. European Mandrake has documented interactions with 2 drug classes — the most serious being anticholinergic drugs (moderate) and oral drugs (moderate) — and none of Interferon Alfa-2b’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

What European Mandrake Itself Has Been Linked To

This is not an interaction — nothing below involves Interferon Alfa-2b. It is the side-effect record for European Mandrake on its own, from the licensed Natural Medicines monograph. If something new turns up after you add European Mandrake, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

Hallucinations / Fainting / Confusion / A severe allergic reaction / An allergic reaction Worth acting on Additional detail
“Orally, European mandrake most commonly causes anticholinergic side effects including confusion, drowsiness, dry mouth, tachycardia, mydriasis, blurred vision, photophobia, decreased urination, decreased sweating and overheating, and flushing (15,17,18). Although some adverse reactions can occur even with low doses, adverse effects are dose related.”

From our pharmacist’s overview on the Interferon Alfa-2b page

“People taking interferon alfa-2b (Intron A, Rebetron) are usually treating hepatitis or a cancer, so the liver may already be under strain, and that is exactly where most of this list points.

About European Mandrake

What is European Mandrake?

Insomnia (traditional)
Pain relief (historical)
Anxiety or depression (folk use)
Gout and aches (traditional)
Sedation or anesthesia (historical)

European mandrake is a highly toxic plant from the nightshade family that was used in ancient and medieval times as a sedative and pain reliever. It contains powerful poisons that can cause serious harm or death, and there is no proof it safely treats any condition. We strongly recommend you do not consume mandrake in any form.

Mandragora officinarum · Solanaceae · Root (and sometimes leaves and fruit) · Historically used as root preparations, extracts, and tinctures; not sold as a safe modern supplement

An interaction check asks whether these two react with each other — it does not ask whether European Mandrake is a good idea for someone in your situation. Here is what our European Mandrake record says about it on its own.

European Mandrake: dosing

There is no safe or established dose of European mandrake. It is not approved or recommended as a dietary supplement, and reputable products are not sold for internal use.Because the plant is highly toxic, we strongly advise against taking it in any amount or form.
