The bottom line No known interaction

We found no known interaction between Bay Leaf 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.

Bay Leaf 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 Bay Leaf 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.

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.

Bay Leaf safety at a glance

Bay Leaf overall Use caution Safe as a food seasoning, but concentrated supplements and essential oil are less studied.
Pregnancy Use caution Food amounts are likely fine, but avoid medicinal or large amounts due to limited safety data.
Breastfeeding Use caution Food amounts are likely fine, but avoid medicinal doses because safety is not well studied.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Rivaroxaban

Interactions in our licensed database are recorded against drug classes, not just single drug names. Rivaroxaban is filed under 5 classifications — including anticoagulant/antiplatelet drugs, p-glycoprotein substrates, cytochrome p450 3a4 (cyp3a4) substrates. Bay Leaf has documented interactions with 3 drug classes — the most serious being antidiabetes drugs (moderate), cns depressants (moderate) and narcotic drugs (moderate) — and none of Rivaroxaban’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

Keep it in perspective

    “Orally, bay leaf is well tolerated when used in amounts found in foods and seems to be well tolerated when the leaf powder is used as medicine. However, the whole, intact leaf can cause severe adverse effects.”

    “Bay leaf can cause allergic reactions, including contact dermatitis. In one case, allergic contact dermatitis occurred with a positive skin test after use of a massage oil containing bay leaf. Another patient developed erythematous plaques on the elbow after applying bay leaves with a topical occlusion for 2 days. The dermatitis resolved after a two-week course of topical corticosteroids.”

Everything above comes from the Natural Medicines adverse-effect record for Bay Leaf — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Rivaroxaban’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Rivaroxaban column appears here.

See Every Supplement That Interacts With Rivaroxaban

This page covers Bay Leaf only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Rivaroxaban page lists 285 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Danshen (major), Grapefruit (major), Piracetam (major) and St. John's Wort (major).

By severity: 5 major · 240 moderate · 40 minor.

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.”

About Bay Leaf

What is Bay Leaf?

Bay Leaf
  • Cooking and flavoring
  • Digestive upset
  • Blood sugar support
  • Colds and congestion
  • Joint and muscle discomfort

Bay leaf is a common culinary herb that is safe in the small amounts used in cooking. Some people take it for digestion, blood sugar, or colds, but strong human evidence for these uses is lacking. Talk to your pharmacist or doctor before using concentrated supplements or essential oils.

Laurus nobilis · Lauraceae · Leaves and essential oil · Whole or ground dried leaves, tea, capsules, extracts, essential oil

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

Bay Leaf: dosing

There is no standardized or proven medicinal dose for bay leaf. In cooking, one or two whole leaves are typically added during simmering and then removed before serving.For teas, extracts, and capsules, follow the directions on the product label, since strength varies widely between products.

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.
