Ginger and medications.
Ginger is not in the Distil recommendation database. We surface it here deliberately, because why a compound is left out is as useful as what we recommend.
Ginger is a kitchen herb with modest supplement evidence, mostly for nausea. It sits in the checker not because it is dangerous but because of its reputation for thinning the blood, and that reputation is worth putting in context. When ginger was actually tested in people taking warfarin, the controlled trials found no meaningful change in INR, in how the body handles warfarin, or in platelet function. What those trials did not measure is bleeding events, and one prospective study that did follow them reported more self-reported bleeding among ginger users, while finding that no herbal supplement predicted a raised INR. So the mechanism is largely theoretical and tied to high-dose supplements rather than food, and the honest position is that the INR question looks settled and the bleeding question does not.
It is outside the Distil recommendation database, and not because the evidence is weak. Ginger's best evidence is for nausea, and every population that evidence covers is one we either decline before payment or do not serve: pregnancy sickness, chemotherapy-induced nausea and nausea after an operation. Its one indication that maps to a goal we do offer is knee osteoarthritis, where the newest and largest pooled analysis found no benefit over placebo, and where Boswellia already sits in our database with better evidence for the same job. As a food it is fine and worth enjoying. The documented pairs below are the antiplatelet watchpoints, which matter most if you take high-dose ginger supplements alongside a blood thinner. Keep your intake steady, and stop high-dose supplements about two weeks before any planned surgery.

We still hold the documented interactions for Ginger, which is why it stays in the interactions checker even though we do not recommend it. Below are the 3 documented pairs we have explicitly assessed: 3 caution. Every call is cited to a clinical reference (PMID) or the British National Formulary.
Documented interactions
Last reviewed 8 June 2026. Each interaction below lists the evidence its assessment drew on: some rest on studies of the exact pair, others on mechanism evidence, where a citation may support one part of the reasoning rather than the exact combination. The evidence line on each entry says which.
Additive anticoagulation
Caution Does Ginger interact with Warfarin sodium?
Ginger has a reputation for thinning the blood, but the controlled studies are reassuring. When ginger was given to people taking warfarin in proper trials, it did not change their INR or how warfarin behaved. A small number of case reports describe raised INR or bleeding, so the safe approach is to keep your ginger intake steady rather than suddenly taking large supplement doses, and to mention it to whoever monitors your INR. There is no need to avoid normal dietary ginger.
Evidence: Limited human data, from small studies or case reports.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Additive antiplatelet effect
Caution Does Ginger interact with Aspirin?
Ginger can mildly reduce platelet stickiness, and aspirin does the same thing through a different route, so in theory taking high-dose ginger supplements alongside aspirin could add to the blood-thinning effect. This is based on how ginger works in the laboratory rather than on studies of people taking both together, so the real-world effect is likely small. Normal dietary ginger is not a concern. If you take high-dose ginger supplements with aspirin, stop them at least two weeks before any planned surgery and tell your dentist or surgeon.
Evidence: No direct study of this exact combination yet; the caution rests on a plausible mechanism or on reports involving a related medicine.
Reviewer-flagged: awaiting clinical-reviewer sign-off.
Caution Does Ginger interact with Clopidogrel?
Both ginger and clopidogrel can reduce platelet stickiness, so in theory high-dose ginger supplements could add slightly to clopidogrel's blood-thinning effect. This is based on how ginger behaves in the laboratory rather than on studies of people taking both together, so any real-world effect is likely small. Dietary ginger is not a concern. If you take high-dose ginger supplements with clopidogrel, stop them at least two weeks before any planned surgery or dental procedure and let the team know.
Evidence: No direct study of this exact combination yet; the caution rests on a plausible mechanism or on reports involving a related medicine.
Reviewer-flagged: awaiting clinical-reviewer sign-off.

How the checker decides
Every result has a source
Each pair we have assessed is cited to a published study (PMID) or the British National Formulary, so you can read the source yourself.
Four kinds of answer
Severe, caution, no known interaction, and not yet assessed. A pair we have not assessed is never shown as clear.
- Severe
- Caution
- No known interaction
- Not yet assessed
Nothing in our data is not a clearance
When nothing in our data records a problem with a pair, the result says no known interaction at typical doses, which is not a clearance: your pharmacist or GP can check the pair against your full medical history.
A full supplement review, built around you, not a generic stack.
The free checker answers one interaction question at a time. A Distil report reviews the bigger picture: your goals, diet, medications, current supplements and any blood results you provide, then shows what appears worth keeping, changing, adding or leaving out.
- what your diet already covers, so you are not adding a capsule for something food is already handling
- which evidence-graded compounds are worth considering for your goals, and which were considered but left out
- what to keep, change or stop from what you already take, plus the order to introduce anything new
- how your medications and complete supplement stack fit together, with daily timing and a clear point for reassessment
The interaction check is one section of the full report. You also get the reasoning behind each recommendation and the evidence references used.
