Feverfew and Blood Thinners: What the Bleeding Risk Means
Feverfew and blood thinners can mix badly: feverfew inhibits platelet activity, so it may add to bleeding risk with anticoagulants or antiplatelet drugs. The size of that risk is not known. SciatiEase holds at most 50 mg of feverfew per serving, plus skullcap, which carries the same warning. Ask your prescriber first.

The warning01
Can you take feverfew with blood thinners?
Only after your prescriber or pharmacist has seen the label, because feverfew may add to bleeding risk.
Feverfew inhibits platelet activity, and that is why reference sources warn about anticoagulants and antiplatelet drugs (MSKCC, Feverfew). It may also slow blood clotting generally (NCCIH, Feverfew).
We found no study of feverfew combined with warfarin, apixaban or aspirin. The warning rests on how the herb acts, so the real-world size of the risk is unknown.
Never stop or change a blood thinner because of a supplement. Stopping apixaban early raises stroke risk (MedlinePlus, Apixaban).
On the label02
How much feverfew is in SciatiEase?
At most 50 mg per 4 capsules, inside a 50 mg blend whose single amounts are hidden.
Ingredients are listed from most to least, so feverfew holds at most 50 mg, and an even split gives 12.5 mg each (21 CFR 101.36 (eCFR)). The exact figure is not printed. A smaller amount may carry less risk, but no source sets a safe level.
| Herb | Most it can hold | Bleeding note |
|---|---|---|
| Feverfew | 50 mg | Inhibits platelets (MSKCC, Feverfew) |
| Passionflower | 25 mg | Anesthesia interaction possible (NCCIH, Passionflower) |
| Chinese skullcap | about 16.7 mg | May add to bleeding risk (MSKCC, Scutellaria baicalensis) |
| Oat straw | 12.5 mg | None found |
Before you start03

Is skullcap a second bleeding flag?
Yes, Chinese skullcap carries a similar warning, plus liver reports (MSKCC, Scutellaria baicalensis).
Read Chinese skullcap and the liver for that side. The who it is for page lists the groups who should ask before ordering.
FAQ05
Feverfew, clotting and your medicines
Does feverfew thin the blood?
It does not thin blood like warfarin, but it inhibits platelet activity and may slow clotting (NCCIH, Feverfew) (MSKCC, Feverfew). That is enough for the bleeding warning.
Is feverfew safe with aspirin?
Both affect platelets, so the effects may add up (MSKCC, Feverfew). No trial tested the pair, so ask your pharmacist before combining them.
Can feverfew be taken with Eliquis?
Apixaban labeling tells patients to report every supplement (MedlinePlus, Apixaban). Feverfew is not named there, but the platelet effect is why we advise asking first.
How long before a procedure should I stop feverfew?
At least 2 weeks before surgery (NCCIH, Feverfew). Tell your surgeon about every supplement, since some raise bleeding risk (NCCIH, Using Dietary Supplements Wisely).
What are signs of bleeding to report?
Unusual bruising, nosebleeds that will not stop, bleeding gums, or black stools are worth a call to your clinician. Severe or sudden bleeding is an emergency.
