How Feverfew Works?

The most effective part of Canthemum parthenium is its leaves. No less than 39 constituents of feverfew have been isolated and studies. There has been different opinions regarding constituents responsible for pharmacological impacts of feverfew. Parthenolide and sesquiterpene lactone are generally considered the most effective constituents of feverfew. Parthenolide appears to decrease the production of pro-inflammatory cytokines like tumor necrotic facto (TNF)-alpha and cyclooxygenase-2. It is believed that a minimum 0.2% of parthenolide is needed for decreasing the symptoms of migraine headache. However, a study utilizing alcohol extract of feverfew regularized to contain 0.35% parthenolide was found ineffectual for curing migraine, recommending that parthenolide may not be the active ingredient and that other constituents of feverfew powder maybe important in decreasing the severity and frequency of migraine headache. However, the mechanism through which Canthemum parthenium counteracts headache is still unclear. It is suggested by clinical studies that extract of feverfew may inhibit discharge of serotonin from leucocytes and platelets and it also restrain platelet aggregation. Feverfew powder may also repress leukotrienes and serum proteases. It also seems to stop prostaglandin synthesis process by inhibiting phospholipase. Initial studies also suggest that parthenolide and fresh feverfew leaves extract may cause irreversible inhabitation of vascular muscle constriction.

What Are The Side Effects /Adverse Reactions of Feverfew?

Using feverfew preparations in traditional ways, like chewing fresh leaves, can cause mouth ulceration, swelling of the lips, inflamed oral and tongue mucosa and sometime loss of taste. Mouth ulceration maybe because of sesquiterpene lactone present in feverfew leaves. Various researchers propose that mouth ulceration is a systemic impact. However, another research utilizing dried Canthemum parthenium capsules reported a higher rate of mouth ulcers in subjects taking placebo than feverfew. The symptoms of syndrome that may develop after using feverfew includes migraine, increased irritability and joint and muscle stiffness, sleep deprivation. Topical - Dermatitis may develop after the oral utilization of Canthemum parthenium.
