Spotted Geranium and Warfarin

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 Warfarin and Spotted Geranium 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 Spotted Geranium at all — not against Warfarin, 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.

  • Kidney problems Worth acting on
  • Hives Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Warfarin. Read the label on DailyMed › Spotted Geranium’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Spotted Geranium side to compare — that is a limit of the record, not a statement that Spotted Geranium has no side effects.

Where does our data come from?

Spotted Geranium 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 Spotted Geranium reference on this page ↓

About Spotted Geranium

What is Spotted Geranium?

  • Diarrhea
  • Mouth and throat sores
  • Bleeding and wound care
  • Hemorrhoids
  • Sore throat gargle

Spotted Geranium (Geranium maculatum), also called wild geranium or cranesbill, is a North American woodland plant whose tannin-rich root has long been used in folk medicine as an astringent for diarrhea, minor bleeding, and mouth or throat irritation. Modern human studies are very limited, so its effectiveness is largely unproven. Talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Geranium maculatum · Geraniaceae · Root and rhizome (sometimes the dried leaves) · Dried root, tea, tincture, powder, capsules

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

Spotted Geranium: dosing

There is no established standard dose for Spotted Geranium. Traditional use involved teas, tinctures, and gargles made from the dried root, but amounts varied widely and were not standardized.If you choose to use a commercial product, follow the directions on the label and do not exceed them.

About Warfarin

What Is Warfarin Used For?

Brand name: Warfarin

Warfarin sodium tablets and Jantoven tablets are both used to prevent and treat venous thrombosis (blood clots in the veins) and pulmonary embolism (a clot in the lungs). They are also used to prevent clot-related complications in people with atrial fibrillation (an irregular heart rhythm) or who have had a heart valve replaced.

In people who have had a heart attack, warfarin is used to reduce the risk of death, another heart attack, stroke, or other clotting events. It does not dissolve an existing clot, but it helps prevent the clot from growing and stops new dangerous clots from forming.
