The bottom line No known interaction

We found no known interaction between Alpine Ragwort and Tofacitinib in our sources. 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Alpine Ragwort and Tofacitinib

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 Tofacitinib and Alpine Ragwort 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 Tofacitinib

Interactions in our licensed database are recorded against drug classes, not just single drug names. Tofacitinib is filed under 4 classifications — including cytochrome p450 2c19 (cyp2c19) substrates, immunosuppressants, cytochrome p450 3a4 (cyp3a4) substrates. Alpine Ragwort has documented interactions with 1 drug class — the most serious being cytochrome p450 3a4 (cyp3a4) inducers (moderate) — and none of Tofacitinib’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

No Interaction Found — But Data Suggests Alpine Ragwort and Tofacitinib May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

  • Liver problems Worth acting on Additional detail

    Alpine Ragwort

    “Orally, the major concern with alpine ragwort use is its pyrrolizidine alkaloid (PA) content. These constituents can cause liver injury. Chronic exposure to other plants containing hepatotoxic PA constituents is associated with veno-occlusive disease. Subacute veno-occlusive disease can cause vague symptoms, including colicky pains, vomiting, diarrhea, and ascites within several days;”

There is insufficient reliable information available about the safety of alpine ragwort products that do not contain hepatotoxic PAs when used during pregnancy.

Lactation Likely Unsafe

When used orally. Hepatotoxic pyrrolizidine alkaloid (PA) constituents in alpine ragwort are excreted in milk. There is insufficient reliable information available about the safety of alpine ragwort products that do not contain hepatotoxic PAs when used during lactation.

From our pharmacist’s overview on the Tofacitinib page

“Supplements deserve genuine care alongside tofacitinib (Xeljanz, Xeljanz XR), a medicine that deliberately dials down the immune system to control conditions like rheumatoid arthritis and ulcerative colitis. Most of the interactions on this page run through the liver enzymes that clear the drug, meaning an herb can push its blood level…”

About Alpine Ragwort

What is Alpine Ragwort?

Alpine Ragwort
  • Traditional wound care
  • Minor bleeding or bruises
  • Digestive complaints
  • Menstrual discomfort
  • Folk remedy for inflammation

Alpine Ragwort is a wild plant in the daisy family that contains pyrrolizidine alkaloids (PAs), which can severely damage the liver. There is no good scientific evidence that it works for any health condition, and the safety risks are serious. We do not recommend using it.

Senecio nemorensis · Asteraceae · Aerial parts (leaves, stems, and flowers) · Dried herb, tea, tincture, and traditional topical preparations

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

Alpine Ragwort: dosing

There is no established safe dose for Alpine Ragwort. Because of its toxic pyrrolizidine alkaloids, health authorities generally advise against taking it internally at all.We do not provide a recommended amount for this plant.

Taking Alpine Ragwort and Tofacitinib Together: Common Questions

Is it safe to take Alpine Ragwort with Tofacitinib?

Do Alpine Ragwort and Tofacitinib have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other.

How was the Alpine Ragwort and Tofacitinib combination checked?
Interactions in our licensed database are recorded against drug classes. Tofacitinib is filed under 4 classifications, and Alpine Ragwort has documented interactions with 1 drug class — none of Tofacitinib's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
