Feverfew is an herb commonly used in alternative medicinal treatments. The plant is typically grown in home gardens and produces a daisy-like flower. Feverfew is commonly used to treat fever and headaches, including migraines. There is little evidence that feverfew helps relieve migraine symptoms. Over time, the body can become addicted to the effects of feverfew leading to symptoms of withdrawal including headaches and pain in joints. There is no connection between feverfew and weight loss.

List of Ingredients

Tanacetum parthenium.

Product Features

Feverfew may be used as a dieting supplement to relieve swelling of joints. The anti-inflammatory effects of the flowering bush have been documented in clinical research on animals, but human studies found no significant effect on inflammation. Feverfew supplements need to be standardized for parthenolides between 0.2% and 0.4%. Clinical studies used supplements standardized to 0.4% parthenolides.

While clinical testing did not find a significant use for feverfew for reducing inflammation in humans, it did find a long list of potential side effects associated with the herb. These side effects may include indigestion, gas, bloating, nausea and vomiting. Diarrhea was also reported. If feverfew has laxative effects on the body, this could be another reason it is included in weight loss supplements.

Laxatives are more commonly utilized in weight loss supplements today. With dieting sometimes comes a lack of natural fiber, especially in diets rich in proteins and fats and short in vegetables and fruits like low carb diets. This could result in constipation that may be treated with natural laxatives. However, natural laxatives are not a viable source of weight loss stimulation. Laxatives can lead to abuse and dependence with prolonged use.

In addition to potential side effects, feverfew may increase bleeding by thinning the blood. This causes a contraindication between feverfew and blood thinners including aspirin and warfarin. Before taking feverfew, patients taking a blood thinner should consult the prescribing physician.

Feverfew is sold online for prices between $2 and $10, depending on the vitamin store selling the product.

  • Feverfew may reduce inflammation.
  • There is some evidence that feverfew reduces pain.


  • There are no weight loss benefits of taking feverfew.
  • Blood thinners should not be taken with feverfew.
  • The herb comes with a long list of potential side effects.


Using an herb like feverfew may seem like a good option if suffering from headaches, joint pain or inflammation during weight loss, but the potential side effects may outweigh any benefits. The side effects associated with feverfew are proven, but any anti-inflammatory benefits are not which increases our skepticism about taking feverfew. Laxative and blood thinning qualities round out the reasons why most dieters should stay away from feverfew.

    I am a heart patient on Plavix. I saw on TV how feverfew helped migraines. Then I read where they thin the blood also plus I have high blood pressure and many other health problems. Do you think it is safe for me to take? I already have a problem with diahrhea. Give me your honest opinion, please.

    I took Feverfew today for the first time (one capsule.) Ended up with severe abdominal pain, nausea, urge to vomit. Spent the rest of the day in bed with very bad stomach pain. The rest of the bottle is going in the trash can!
