A double-flowered variety.


Slight resemblance : The white outer petals of the flowers, like Sneezewort are rather few in number and wider than is usual for a Daisy-type plant, fewer even than the few petals of Feverfew, but they appear cleaner in Feverfew. Also, the central florets of Sneezewort are cream coloured rather than the brilliant yellow of Feverfew.

Uniquely identifiable characteristics

Distinguishing Feature : The few white petals are only about a dozen in number and wider than most daisy-type flowers. Together with the central yellow florets, it is quite distinctive.

This is a garden plant, with short white rays surrounding a set of central yellow disc florets. The rays are often doubled. It is synonymous with chrysanthemum parthenium and with pyrethrum parthenium, and as its' latter name suggests contains pyrethrum. Feverfew has a smell reminiscent of camphor.

Feverfew has long been known as a healing herb for a variety of ailments such as headaches, migraine, tinnitus, toothaches, insect bites, psoriasis, asthma, dizziness, arthritis, nausea, vomiting, infertility and problems with menstruation and labour during childberth. It relieves migraines by preventing the blood vessels within the brain from going into spasm. It can aid digestion and is used in some digestive aperitifs. It can cause problems over prolonged periods of intake. The leaves contain an irritant which can cause mouth ulcers.

It is widely cultivated in large regions of the World for its pharmaceutical properties.

a SESQUITERPENE LACTONE

It contains parthenolide, an allergenic sesquiterpene lactone which has a reactive exo-cyclic methylene group, which can form bonds with the thiol groups in proteins. Parthenolide occurs with greatest concentration in the flowers and fruit of Feverfew.

The ESSENTIAL OIL


The essential oil of Tansy consists of a number of volatile monoterpenoids that contribute to the overall strong smell; these include Camphor, Camphene, Germacrene D, p-Cymene, Terpinen-4-ol (aka 1-Terpinene-4-ol), Borneol, Chrysanthenyl Acetate and other compounds. Note that Chrysanthenyl Acetate has a cyclo-butane group within it. Chrysanthenyl Acetate is Myrtenol with an added acetate group.

METHOXY FLAVONOIDS


The lipophilic flavonol Tanetin is another of pharmacologically active ingredient of Feverfew. Tanetin (6-hydroxykaempferol 3,7,4'-trimethylether) may contribute to the anti-inflammatory properties of Feverfew which is so useful for migraines. It is found in both the seeds and the leaves and occurs together with other methoxy flavonols such as Santin, Chryseriol, Centaureidin and Jaceidin. several flavones such as Luteolin and its 7-glucoronide, Apigenin and its 7-glucoronide and Quercetin.



Also, several flavones such as Luteolin and its 7-glucoronide, Apigenin and its 7-glucoronide and Quercetin.


Its botanical name parthenium stems from the Greek word parthenos meaning 'virgin' which alludes to its mediaeval use in treating menstrual problems.

The leaves of Feverfew smell aromatic when crushed.
