Like all herbs, there are some precautions you should take before using feverfew medicinally.
Feverfew Preparations and Dosage
Feverfew is dried for tinctures, capsules, and infusions. Since feverfew is a lovely garden plant and easy to grow, many herbalists recommend that headache sufferers plant it in their yards, where it will be readily available. Pick two to four leaves each day and allow them to dry in your kitchen.
The dosage of feverfew depends on the type and quality of the product used. Consuming two to three of the bitter-tasting dried leaves each day constitutes a medicinal dosage. Limit consumption to a maximum of four or five leaves a day. If mouth irritation occurs, switch to tincture or capsules.
Feverfew Precautions and Warnings
Feverfew is sometimes called tansy, but do not confuse feverfew (Tanacetum parthenium) with the herb tansy (Tanacetum vulgare) or with various Senecio species commonly known as the ragworts, which are sometimes also referred to as tansy. Senecio ragwort contains extremely toxic substances (pyrrolizidine alkaloids) that can damage your liver. You can see the value of using botanical versus common names here. Avoid feverfew in pregnancy because it may increase the risk of bleeding or even induce abortion of the fetus.
Side Effects of Feverfew
Feverfew can cause stomach upset. Chewing the raw leaves, day after day, can irritate the mouth, but the irritation subsides once you stop chewing the leaves. Tinctures and capsules do not irritate the mouth. Using the fresh plant also can cause a skin rash. Since feverfew relaxes blood vessels, it can increase blood flow during menstruation. Keep feverfew out of reach of children. More research is needed to determine the herb's long-term safety.
