Adults (18 years and older)
2 to 3 dried leaves (approximately 60 milligrams) have been taken daily, or 50 to 250 milligrams of a dried leaf preparation taken daily, standardized to 0.2% parthenolide (a common dose is 125 milligrams daily). Human studies have used 50 to 114 milligrams of feverfew powdered leaves daily, packed into capsules, standardized to 0.2% parthenolide, or 0.50 milligrams of parthenolide daily. Doses of 70 to 86 milligrams of dried chopped feverfew leaves in capsules, taken once daily, have also been used.
Children (younger than 18 years)
There is not enough scientific information to safely recommend feverfew for use in children.
SafetyDISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.
Feverfew may cause allergy in people allergic to chrysanthemums, daisies, marigolds, or other members of the Compositae family, including ragweed. There are multiple reports of allergic skin rashes after contact with feverfew.
Side Effects and Warnings
Few side effects are reported in human studies of feverfew. The side effects that do occur are usually mild and reversible. Mouth inflammation or ulcers, including swelling of the lips, tongue irritation, bleeding of the gums, and loss of taste, have been reported and usually occur after direct contact of the mouth with the leaves, although some people report burning after swallowing a capsule containing dried leaf. Photosensitivity (sensitivity to sunlight or sunlamps) has been reported with other herbs in the Compositae plant family and may be possible with feverfew as well. Indigestion, nausea, flatulence, constipation, diarrhea, abdominal bloating, and heartburn have been reported rarely in human studies. Gardeners may develop skin irritation at sites of contact with feverfew plants. Feverfew can also cause allergic rashes. One small study reported increased heart rate in some patients.
Laboratory tests suggest that feverfew affects blood platelets and in theory may increase the risk of bleeding. However, this has not been clearly shown in humans. Nonetheless, caution is advised in patients with bleeding disorders or taking drugs that may increase the risk of bleeding. Dosing adjustments may be necessary. Use caution prior to some surgeries or dental procedures, due to a theoretical increase in bleeding risk.
Pregnancy and Breastfeeding
There is not enough information about safety to recommend feverfew during pregnancy or breastfeeding. Traditional experience suggests that feverfew may stimulate menstrual flow and induce abortion, and therefore should be avoided.
