Can You Take Turmeric and Warfarin Together?

Evidence on turmeric and warfarin is mixed -- neither drug's own current label documents a direct interaction, but outside case-level evidence conflicts.

Insufficient evidenceEvidence: Low

What the interaction means

Neither side's primary source states a direct interaction: warfarin's FDA label does not name turmeric (its Botanical Products section names only co-enzyme Q10, St. John's wort, and ginseng as effect-decreasing botanicals), and NCCIH's turmeric page does not mention warfarin. However, this catalog's own prior research (see docs/content-research-manifest.md) found conflicting case-level evidence outside these two primary sources: a government (Medsafe New Zealand) case report of a patient's INR rising above 10 after starting a turmeric product, versus a controlled interaction study of one specific high-bioavailability turmeric/curcumin formulation (Meriva) finding no INR interference. That mixed evidence was the reason this pair was deferred rather than published in an earlier session, and it is not resolved by this record.

Practical context

Given warfarin's boxed bleeding-risk warning and the conflicting case-level evidence, this is treated as a genuine mixed-evidence outcome rather than a clean 'no interaction' finding -- anyone on warfarin should discuss turmeric/curcumin supplementation with the prescriber managing anticoagulation rather than treating the absence of an FDA-label mention as reassurance.
