The bottom line No known interaction

We found no known interaction between Hartstongue and Temsirolimus 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.

Hartstongue and Temsirolimus

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 Temsirolimus and Hartstongue 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Hartstongue at all — not against Temsirolimus, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

What Temsirolimus’s Own FDA Label Lists

This is not an interaction — none of it involves Hartstongue. These are the most notable effects listed in the ADVERSE REACTIONS section of Temsirolimus’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Pain or burning when passing urine Worth acting on
  • High blood sugar Worth acting on
  • Shortness of breath Worth acting on mentioned in 4.8% of FDA reports for Temsirolimus
  • Chest pain Worth acting on
  • Low mood Worth acting on
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on
  • Anemia Worth acting on
  • A low white blood cell count Worth acting on
  • A higher chance of infection Worth acting on mentioned in 4.2% of FDA reports for Temsirolimus

Showing the 10 most notable of 37 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Temsirolimus. Read the label on DailyMed › Where a percentage is shown, it is the share of 4,499 voluntary FDA FAERS reports for Temsirolimus that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Hartstongue’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Hartstongue side to compare — that is a limit of the record, not a statement that Hartstongue has no side effects.

From our pharmacist’s overview on the Temsirolimus page

“Temsirolimus (Torisel), an infusion for advanced kidney cancer, deserves genuine wariness around supplements. Most interactions on record involve herbs that alter CYP3A4, the liver enzyme that clears the drug, so a capsule can quietly raise its levels and side effects or thin out its anticancer effect.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Hartstongue is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Hartstongue reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Hartstongue and Temsirolimus records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Hartstongue

What is Hartstongue?

  • Cough and chest congestion
  • Digestive complaints
  • Liver and spleen support (traditional)
  • Mild diarrhea
  • Wound healing (topical, traditional)

Hartstongue is a fern that has been used in traditional European herbal medicine, mainly for coughs and digestive complaints. There is very little modern scientific research to confirm that it works for any health condition, so its effectiveness is largely unproven. If you are considering it, talk with a pharmacist or doctor first, and avoid it during pregnancy and breastfeeding.

Asplenium scolopendrium · Aspleniaceae · Leaves (fronds) · Dried herb, tea/infusion, tincture

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

Hartstongue: dosing

There is no established, scientifically supported dose for Hartstongue. Traditional use involved brewing the dried fronds as a tea, but standardized amounts have not been set through modern research.If you choose to use a commercial product, follow the directions on the label and do not exceed them.
