Can you take feverfew and turmeric together? The risks of a potent combination
Many individuals are drawn to herbal supplements like feverfew and turmeric for their purported anti-inflammatory and pain-relieving benefits. Feverfew is commonly associated with migraine prevention, while turmeric, with its active compound curcumin, is celebrated for its antioxidant and anti-inflammatory properties. However, despite their individual potential, combining these two supplements presents a significant safety risk that should not be overlooked.
The shared blood-thinning mechanism
The primary danger in taking feverfew and turmeric together lies in their synergistic blood-thinning effects. Both herbs act as antiplatelet agents, inhibiting the aggregation of platelets that form blood clots.
- Feverfew's Antiplatelet Action: Feverfew contains parthenolide which has been shown to inhibit platelet activity, slowing blood clotting.
- Turmeric's Anticoagulant Properties: Curcumin, in turmeric, also has antiplatelet and anticoagulant properties.
When combined, the anti-clotting effects are amplified, dramatically increasing the risk of abnormal bleeding, bruising, and other hemorrhagic complications. This is especially dangerous for individuals with pre-existing bleeding disorders or those taking prescription blood-thinning medications.
Significant drug interactions
Combining feverfew and turmeric also poses risks due to their interactions with various medications.
- Prescription Blood Thinners: This combination with anticoagulants like warfarin can lead to dangerously high INR levels and severe bleeding.
- NSAIDs: Combining with NSAIDs like ibuprofen also increases bleeding risk.
- Liver Metabolism and Other Drugs: Both can affect liver enzymes that metabolize medications, potentially altering drug effectiveness.
Potential side effects and special considerations
Besides increased bleeding risk, combining these supplements can cause gastrointestinal distress, mouth ulcers, or allergic reactions.
Who should avoid this combination?
- Pregnant and Breastfeeding Women: Feverfew can cause uterine contractions, increasing miscarriage risk. Safety during breastfeeding is also not established.
- Individuals with Bleeding Disorders: Avoid this combination completely if you have a bleeding disorder.
- Upcoming Surgery: Stop taking both supplements at least two weeks before any surgery to prevent excessive bleeding.

The importance of professional medical advice
Before starting any new supplement, particularly a combination like feverfew and turmeric, consult a qualified healthcare provider. They can assess your health, conditions, and medications to determine the safest course. Do not self-prescribe or combine supplements based on anecdotal evidence, as risks outweigh potential benefits.
For more general information on feverfew, you can refer to authoritative sources such as the National Center for Complementary and Integrative Health (NCCIH).
Conclusion
It is not recommended to take feverfew and turmeric together due to their combined antiplatelet activity, which significantly increases bleeding risk. This risk is compounded with prescription medications like anticoagulants and NSAIDs. Seeking guidance from a healthcare professional is the only safe approach for using these or other herbal remedies.
