Most plain, caffeine-free herbal teas are fine while taking Eliquis, but a handful of popular varieties carry real interaction risks. The teas to watch out for are chamomile, green tea in large amounts, and any blend containing ginkgo biloba, St. John’s wort, ginger, or turmeric. Beyond those, you have plenty of safe options.
Eliquis (apixaban) works differently from older blood thinners like warfarin, so the dietary rules are less strict overall. But it’s still processed through specific pathways in your body that certain plant compounds can disrupt, either raising bleeding risk or making the drug less effective.
Teas That Can Cause Problems
The biggest concerns fall into two categories: teas that increase bleeding risk on top of what Eliquis already does, and teas that change how your body absorbs or breaks down the drug.
Chamomile tea contains natural coumarin compounds that have their own mild blood-thinning effect. Layered on top of Eliquis, this can increase your risk of bruising or bleeding. Memorial Sloan Kettering Cancer Center flags chamomile specifically for its ability to enhance anticoagulant effects and inhibit platelet activity. A case report documented multiple internal hemorrhages in a 70-year-old woman who used chamomile products alongside an anticoagulant. One cup on a rare occasion is unlikely to cause a crisis, but regular daily chamomile is worth avoiding.
Green tea is complicated. The tea leaves themselves are rich in vitamin K (120 to 625 micrograms per 100 grams of dry leaf), but here’s the thing: vitamin K primarily interferes with warfarin, not Eliquis. Eliquis works on a completely different clotting mechanism that vitamin K doesn’t affect. The concern with green tea is different. It contains compounds that can interfere with the enzymes your liver uses to break down Eliquis, potentially causing the drug to build up in your system. A cup here and there is unlikely to be meaningful, but drinking several cups daily could raise your effective dose and increase bleeding risk.
Ginkgo biloba tea has its own antiplatelet properties, meaning it slows clotting through a separate pathway. Combined with Eliquis, this creates an additive bleeding risk. Research classifies the interaction between ginkgo and direct oral anticoagulants as moderate in severity. If you see ginkgo on an ingredient list, skip that blend.
St. John’s wort tea is a different kind of problem. Instead of increasing bleeding, it does the opposite: it ramps up the liver enzymes (CYP3A4) and transport proteins (P-glycoprotein) that clear Eliquis from your body. The result is lower drug levels in your blood, which means less protection against blood clots. The FDA-approved prescribing information for Eliquis specifically names St. John’s wort as something to avoid. This one isn’t a “use caution” situation. It’s a clear no.
Ginger and Turmeric Teas Need Caution
Both ginger and turmeric are classified as “consider therapy modification” when used alongside Eliquis, which in practical terms means they’re worth being careful about. Both have natural antiplatelet activity. Turmeric’s active compound inhibits platelet clumping through multiple mechanisms, including blocking signals that tell platelets to stick together. Ginger works similarly.
A study on over-the-counter product interactions with Eliquis found that roughly one-third of people taking the drug were using at least one product with potentially serious interactions on a daily or near-daily basis. Turmeric and ginger were among the most common. The tricky part is that this interaction information isn’t printed on the Eliquis package insert, so many people have no idea there’s a concern. A turmeric latte every day or a strong ginger tea habit could meaningfully raise your bleeding risk over time. An occasional cup with a small amount of either ingredient is lower risk, but daily concentrated doses are best avoided.
Teas That Are Generally Safe
Plenty of teas don’t interact with Eliquis in any known way. These are your go-to options:
- Peppermint tea: no known anticoagulant or enzyme interactions
- Rooibos (red bush) tea: naturally caffeine-free with no clotting effects
- Hibiscus tea: safe for most people on anticoagulants
- Lemon balm tea: mild and free of relevant interactions
- Plain black tea: in moderate amounts (one to two cups daily), black tea is not flagged for Eliquis interactions
- Fruit-based herbal teas: blends made from dried fruit, rose hips, or berry flavors are generally fine
The key with any of these is checking the ingredient list on blended teas. A “relaxation blend” might contain chamomile. A “wellness tea” might include turmeric or ginkgo. Single-ingredient teas are the easiest to keep track of.
Why Eliquis Is Different From Warfarin
If you’ve heard that people on blood thinners need to worry about vitamin K in leafy greens, that advice applies to warfarin, not Eliquis. Warfarin works by blocking vitamin K’s role in producing clotting factors, so eating a lot of vitamin K-rich food directly weakens the drug. Eliquis works on a completely different target (Factor Xa), so vitamin K intake doesn’t affect its performance.
What does matter for Eliquis is anything that affects CYP3A4 enzymes or P-glycoprotein transporters, because those are the systems your body uses to process and eliminate the drug. Substances that rev up those systems (like St. John’s wort) flush Eliquis out too fast. Substances that slow those systems down can cause the drug to accumulate. This is why grapefruit juice is also on the avoid list, and why the interaction profile for Eliquis looks different from warfarin’s.
Practical Tips for Tea Drinkers on Eliquis
Read ingredient labels on every herbal blend before buying. “Herbal tea” is a broad category, and many blends combine six or more botanicals. Even small amounts of a problematic herb, consumed daily, can add up. If you buy loose-leaf tea from a shop or market where ingredients aren’t always labeled clearly, ask what’s in it.
Stick to one to two cups per day of any single tea, even the safe ones. Moderation limits your exposure to any compounds that might be present in trace amounts. If you’re a three-or-four-cup-a-day tea drinker, rotating between a few safe varieties is a smart approach.
If you’ve been drinking chamomile or ginger tea regularly and didn’t know about these interactions, don’t panic. Mention it to your prescriber at your next visit. They may want to check your levels or simply confirm that your current routine isn’t causing problems. The risk from occasional, moderate consumption is low for most people, but daily, concentrated use is where real issues tend to surface.
