The bottom line No known interaction

We found no known interaction between Field Scabious and Rivaroxaban 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.

Field Scabious and Rivaroxaban

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 Rivaroxaban and Field Scabious 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 Field Scabious at all — not against Rivaroxaban, 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 Rivaroxaban’s Own FDA Label Lists

This is not an interaction — none of it involves Field Scabious. These are the most notable effects listed in the ADVERSE REACTIONS section of Rivaroxaban’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. 5 of them are worth acting on rather than waiting out — marked below.

  • Bleeding in the gut Worth acting on mentioned in 10.5% of FDA reports for Rivaroxaban
  • Bleeding or bruising Worth acting on mentioned in 17.6% of FDA reports for Rivaroxaban
  • A stroke or mini-stroke Worth acting on
  • Blood clots Worth acting on
  • An irregular heartbeat Worth acting on
  • Cough
  • Vomiting

From the ADVERSE REACTIONS section of the FDA label for Rivaroxaban. Read the label on DailyMed › Where a percentage is shown, it is the share of 205,037 voluntary FDA FAERS reports for Rivaroxaban that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Field Scabious’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Field Scabious side to compare — that is a limit of the record, not a statement that Field Scabious has no side effects.

From our pharmacist’s overview on the Rivaroxaban page

“Grapefruit is the interaction I would flag first for anyone taking rivaroxaban (Xarelto). It slows how the body clears this blood thinner, and higher levels mean more bleeding risk.”

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

What is Field Scabious?

  • Skin conditions like eczema and minor wounds
  • Cough and chest complaints
  • Sore throat
  • Mild digestive upset
  • Traditional 'blood cleansing' remedies

Field Scabious is a wild-growing herb used in European folk medicine, mostly for skin problems, coughs, and sore throats. There is very little modern scientific research to confirm any of these uses, so it should be viewed as a traditional remedy rather than a proven treatment. Talk to your pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or taking other medicines.

Knautia arvensis · Caprifoliaceae · Aerial parts (flowers, leaves, and stems), occasionally the root · Tea (infusion), tincture, dried herb, topical washes or compresses

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

Field Scabious: dosing

There is no established, standardized dose for Field Scabious. It has traditionally been prepared as a tea from the dried aerial parts or as a tincture, but reliable dosing guidelines from clinical research do not exist.If you choose to use a commercial product, follow the directions on the label and do not exceed them.

About Rivaroxaban

What Is Rivaroxaban Used For?

Brand name: Xarelto

Rivaroxaban tablets are used to reduce the risk of stroke in adults with nonvalvular atrial fibrillation (an irregular heart rhythm), treat deep vein thrombosis (DVT, a blood clot in a vein) and pulmonary embolism (PE, a blood clot in the lungs), and lower the chances of these clots coming back. They also help prevent clots after hip or knee replacement surgery, protect hospitalized patients at risk for clots, and — in combination with aspirin — reduce the risk of major cardiovascular events in adults with coronary artery disease (CAD) or peripheral artery disease (PAD).

Rivaroxaban tablets are also approved for treating VTE (venous thromboembolism, blood clots in veins) and preventing recurrence in pediatric patients from birth to under 18 years, and for preventing clots in children aged 2 and older with congenital heart disease after the Fontan procedure. Rivaroxaban for oral suspension (available as Rivaroxaban Granule and Xarelto oral suspension) is specifically indicated for these two pediatric uses.
