The bottom line No known interaction

We found no known interaction between Oriental Arborvitae and Apixaban 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.

Oriental Arborvitae and Apixaban

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 Apixaban and Oriental Arborvitae 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 Oriental Arborvitae at all — not against Apixaban, 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 to actually watch for

What Oriental Arborvitae Itself Has Been Linked To

This is not an interaction — nothing below involves Apixaban. It is the side-effect record for Oriental Arborvitae on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Oriental Arborvitae, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

  • Hallucinations / Kidney problems Worth acting on Additional detail

    “Orally, taking oriental arborvitae long-term or at high doses might cause adverse effects due to the thujone constituent. Thujone-containing herbs can cause restlessness, vomiting, dizziness, tremors, kidney damage, hallucinations, and convulsions when used long-term or at high doses. Thujone intoxication can cause psychoactivity similar to tetrahydrocannibinol, the active constituent in marijuana. (12).”

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

From our pharmacist’s overview on the Apixaban page

“St. John's wort can weaken apixaban (Eliquis), speeding how the body clears this blood thinner and leaving you less protected from the strokes and clots it is prescribed to prevent.”

About Oriental Arborvitae

What is Oriental Arborvitae?

Oriental Arborvitae
  • Insomnia and restlessness
  • Constipation (seeds)
  • Hair loss and scalp health (topical)
  • Bleeding and heavy menstruation (traditional)
  • Cough and respiratory complaints

Oriental Arborvitae is an evergreen conifer used in Traditional Chinese Medicine, where the seeds (Bai Zi Ren) are taken to calm the mind and ease constipation, and the leaves (Ce Bai Ye) are used for bleeding and hair loss. Solid human evidence for these uses is limited, and parts of the plant can be toxic if misused. Talk with a pharmacist or doctor before trying it, and avoid it in pregnancy.

Platycladus orientalis · Cupressaceae · Seeds (Bai Zi Ren) and leaves/twigs (Ce Bai Ye) · Dried seeds, dried leaf, decoctions (teas), powders, capsules, and topical preparations

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

Oriental Arborvitae: dosing

There is no well-established standardized dose for Oriental Arborvitae as a supplement. In Traditional Chinese Medicine, the seeds and leaves are used in specific amounts within formulas prepared by a trained practitioner, and the right amount depends on the part used and the preparation.If you choose to use a commercial product, follow the directions on the label and do not exceed them. Never ingest the concentrated essential oil unless directed by a qualified professional.

About Apixaban

What Is Apixaban Used For?

Brand name: Eliquis

Apixaban is used to reduce the risk of stroke and dangerous clots traveling through the body in adults with nonvalvular atrial fibrillation (an irregular heart rhythm not caused by a heart valve problem). It is also used to prevent deep vein thrombosis (DVT — a blood clot in the leg) in adults after hip or knee replacement surgery, and to treat DVT and pulmonary embolism (PE — a blood clot in the lungs) in adults, including reducing the risk of those clots coming back.

Eliquis (the brand-name tablet and kit) is additionally approved to treat venous thromboembolism (VTE — blood clots in the veins) and reduce the risk of recurrent VTE in pediatric patients from birth and older, after at least 5 days of initial anticoagulant treatment. The generic apixaban tablet carries the adult indications only.
