Yellow Loosestrife and Tyropanoate

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 Tyropanoate and Yellow Loosestrife 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 Yellow Loosestrife at all — not against Tyropanoate, 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 Tyropanoate page

“Tyropanoate (Bilopaque) is an oral contrast dye, swallowed so a gallbladder X-ray has something to show, which is exactly why this list deserves real attention. Every one of the 17 supplements on it can change how much of the dye actually gets absorbed, and a poorly absorbed dose can mean a failed or repeated scan.”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Yellow Loosestrife 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 Yellow Loosestrife reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Yellow Loosestrife and Tyropanoate 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 Yellow Loosestrife

What is Yellow Loosestrife?

  • Diarrhea and digestive upset
  • Minor wounds and bleeding
  • Mouth and throat irritation
  • Mild gastrointestinal complaints

Yellow loosestrife (Lysimachia vulgaris) is a traditional European herb used mostly for diarrhea, minor bleeding, and mouth or throat irritation. There is very little modern scientific evidence to confirm it works, and its safety has not been well studied, so it should be used cautiously and avoided in pregnancy and breastfeeding.

Lysimachia vulgaris · Primulaceae · Aerial parts (leaves, stems, and flowers) · Tea (infusion), tincture, dried herb, occasionally topical preparations
