Frostwort + Upadacitinib Hemihydrate
Upadacitinib Hemihydrate brand name: Rinvoq.
We found no known interaction between Frostwort and Upadacitinib Hemihydrate 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.
Frostwort and Upadacitinib Hemihydrate
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 Upadacitinib Hemihydrate and Frostwort 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 Frostwort at all — not against Upadacitinib Hemihydrate, 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.

From our pharmacist’s overview on the Upadacitinib Hemihydrate page
“Grapefruit is the pairing I would want anyone on Rinvoq (upadacitinib) to know about first. The drug is cleared by a liver enzyme called CYP3A4, and grapefruit blocks that enzyme, letting blood levels climb, which matters for a medicine that already dials down the immune system.”

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Frostwort 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 Frostwort reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Frostwort and Upadacitinib Hemihydrate 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 Frostwort
What is Frostwort?
- Sore throat and mouth irritation
- Diarrhea
- Skin conditions and ulcers (topical)
- Scrofula (historical/traditional use)
- General astringent tonic
Frostwort is a North American wildflower used in traditional and folk herbal medicine, mainly as an astringent for sore throats, diarrhea, and skin problems. There is very little modern scientific research to confirm that it works or to define a safe dose, so it should be used cautiously and only after talking with a healthcare professional.
Helianthemum canadense · Cistaceae · Whole plant (leaves and aerial parts) · Dried herb, tea (infusion), tincture, sometimes topical preparations
