Traditional
LAntonelli (1941) says that all the plant is tonic, febrifuge,stimulant, antispasmodic, emmenagogue and antiflatulent , hesays that it was very well known to the old physicians. The flowers are used both fresh or dried, particularly in case of dysmenorrhea .
Dosage : herbal tea made with 4-16g /L, 3-4 glasses during the

Sesquiterpenlactones in Feverfew: not only Parthenolide
The activity of Parthenolide is 1/24 of the activity of an extractobtained from a drug rich in flowers.
Costunolide is more active as antinflammatory than perthenolide.(Koo TH, Lee JH, et al., 2001.

Extracts Pharmacology An interesting study
An extract DEPLETED of parthenolide showedantinflammatory activity:
direct inhibition of lypoxygenase
inhibition of release of different
inflammatory mediators (PGE2, NO,TNF- , IL-2 etc. )

The Original Sin
and the City of London
Going back to the origin of theEvidence Based Dosage (?!)
Johnson ES, Kadam NP et al., 1985. Efficacy of feverfew asprophylactic treatment of migraine . BMJ 291:569- 573.
RCT, double blind, placebo controlled 20 subjects (City of London Migraine Clinic) that were used to self
treating with feverfew fresh leaves.
COULD THEY HAVE USED THE FLOWERS?

The Beginning or Going back to thedosage
Each freeze dried leaf containing five leaflets weighed a mean of 25.7 mg.
The mean daily dose of feverfew used by patients before entry to thestudy was 2.44 leaves (roughly 60mg). We therefore decided that the dose of each capsule should be fixed at 25 mg and that each
patient should receive two capsules daily .
Today recommended dosage: powder: 50-120 mg/die
Roughly: 5-20 times lower than the traditional dosage
Modern-traditional Two teaspoonfuls as herbal tea. 2-3 cups before meals, regularly for a
few months.Wichtl M (ed.) 2004. Herbal Drugs and Phytopharmaceuticals. Handbook for a practice on a scientific basis.3rd edition. Stuttgart, medoharm Scientific publishers.

Summary of Pharmacological studies on aextract from Aerial part rich of flowers .
Content of parthenolide correlates withactivity only in the migraine model.
Content of total flavonoids, by itself, doesnot correlate with activity and does not explainthe difference in activity of different extracts.
CONCLUSION FROM Historical and traditional data and
information: leaves, aerial part, or flowers could be used. dosage can be quite high (specifically in acute
conditions)
The dosage supported by clinical trial in theprophylaxis of migraine
is not based on traditional use but on a very specificand unusual one. It is very low due to the fact that patients ate fresh
leaves. (They could very difficulty could ate other parts!)
CONCLUSION Phytochemistry shows that many active
constituents (es. different kind of sesquiterpenlactones or flavonoids) make thephytocomplex of flowers similar but not equal tothat one of leaves and standard aerial parts.
It would be possibile that extracts from a drug based or rich in flowers is more/the mostactive in acute conditions and at high dosage .
