Tanacetum parthenium Identity & Plant Part
The botanical entity is Tanacetum parthenium (L.) Sch.Bip., feverfew, a short-lived aromatic perennial of the Asteraceae with divided, yellow-green leaves and button-shaped flower heads with white rays. It was long listed as Chrysanthemum parthenium. The part used is the aerial part. The root is not part of this ingredient.
Feverfew is easily confused with other daisy-like herbs, including tansy, Tanacetum vulgare, and with chamomile, which is why the botanical name matters. The herb carries parthenolide, a sesquiterpene lactone, along with volatile oil and flavonoids, named only as constituent families. Parthenolide is unstable to heat, acid and alkali, which shapes how an extract is made.
Feverfew is gathered as the flowering herb and dried before extraction, and the dried aerial parts are the starting material for the ratio extract.
