Action And Clinical Pharmacology: Clinical trials conducted in the United Kingdom have established the effectiveness of feverfew (Tanacetum parthenium) when taken daily over a 2-month period in reducing the frequency and intensity of migraine attacks.
Tanacet 125 contains specially prepared and standardized feverfew leaf (Tanacetum parthenium) which is a recognized traditional herbal remedy for several conditions, including the prevention of migraine headache. As with most migraine preventative therapies, the exact method of action remains to be defined; however, clinical trials have demonstrated that the drug reduces the frequency and severity of migraine attacks. Additionally, the drug reduces the severity of migraine associated gastro-intestinal upset (nausea, vomiting).
Although the interrelated role of several biological principles may be important, a sesquiterpene lactone, parthenolide, has been accepted as a biological marker for antimigraine activity of the herbal product. Only a product that has a minimum of 0.2% parthenolide demonstrates a correlation with biological activity. This product is certified to contain 125 mg of feverfew leaf material per tablet with a minimum parthenolide assay equal to or exceeding the 0.2% parthenolide requirement. This differentiates Tanacet 125 from other feverfew products.
In vitro studies have demonstrated that parthenolide acts to inhibit the release of serotonin from platelets and white blood cells. The clinical significance of this observation is not presently understood.
