Feverfew

An herb that has been most commonly used for migraine headaches. Feverfew can cause allergic reactions, especially in persons who are allergic to chamomile, ragweed, or yarrow. Nonsteroidal anti-inflammatory drugs (NSAIDs such as ibuprofen /Advil, Motrin or naproxen /Aleve) can reduce the effect of feverfew. A condition called "postfeverfew syndrome" features symptoms including headaches, nervousness, insomnia, stiffness, joint pain, tiredness, and nervousness. Feverfew can impair the action of the normal blood clotting element (platelets). It should be avoided in patients taking medications to prevent blood clotting (anticoagulants) such as warfarin/Coumadin.
