The Active Ingredient Is: Parthenolide

Parthenolide is a bioactive compound found in feverfew, a traditional herb used for brain health support. It is a key constituent linked to anti-inflammatory and vasomodulatory properties within feverfew preparations.

This form is derived from feverfew aerial parts and is standardised to 0.5%–0.7% parthenolide per capsule, with feverfew powder also included to balance the effect.

What Does Parthenolide Do?

Parthenolide helps modulate inflammatory processes and vascular tone, aligning with normal bodily functions of inflammation control and blood vessel regulation. It is linked to the inhibition of serotonin and prostaglandin release from certain cells, which may relate to migraine pathways.

This information is shared to describe the nutrient's role in normal physiology and is supported by established scientific understanding in the field.
