Feverfew (Tanacetum parthenium) is a flowering plant that can be used medicinally for a wide range of ailments. The dried leaves of the feverfew plant are taken orally to treat gastrointestinal complaints, menstrual abnormalities and migraine headaches, according to the University of Maryland Medical Center (UMMC). It's important to use feverfew appropriately to avoid drug interactions or other complications.
Step 1
Speak to your doctor to determine whether you are an good candidate for using feverfew. Women who are pregnant should not use this herb, as it can induce preterm labor. Nursing mothers are also discouraged from taking feverfew; the herb may pass into breast milk and potentially harm your baby.
If you take anticoagulant medications---blood thinners---consult your doctor before using feverfew.
Step 2
Choose the form of feverfew that will be easiest for you to take. According to the National Center for Complementary and Alternative Medicine (NCCAM), the herbal supplement is available as a liquid extract or tincture, as well as in capsules or tablets that you can swallow. The form of supplement you take is a personal choice.
Step 3
Weigh yourself so that you take the appropriate dose of feverfew, according to UMMC. Adult standard dosages are based on an average weight of 150 lb. and range from 100 to 300 mg in capsule or tablet form, or between 60 and 120 drops of liquid.
If you weigh significantly more or less than 150 lb., you may need to adjust your dosage, under the supervision of your doctor.
Step 4
Confirm that your feverfew tablets or capsules are standardized to between 0.2 and 0.4 percent parthenolides---this information should be listed on the supplement label. Parthenolides are compounds that prevent and relieve muscle spasms, and prevent the blood vessels from constricting, and are the active ingredient in feverfew.
Step 5
Take solid forms of feverfew with a glass of water. If you are taking a tincture, mix one part herb with an equal part of water. Mix one part liquid extract with five parts of water, and drink the dose.
Proper use of the supplement can prevent unpleasant side effects involving the digestive system or instances of toxicity.
Step 6
Take feverfew two to three times daily, or as directed by your doctor, as symptoms occur. Gradually step down from using the herb after one week of continuous use, to avoid withdrawal symptoms. Your medical care provider can help you determine how best to stop taking the supplement.
