Available in superior extended delivery, the aromatic plant Feverfew has been used since the Middle Ages. Nature's Plus Herbal Actives Feverfew leaf extract (500 mg) is uniformly standardized to a minimum of 0.7% (3.5 mg) parthenolide to guarantee that each and every capsule provides consistent potency and activity. Each capsule, providing the greatest concentration of active botanical principles, maximizes the synergistic benefits of the whole leaf, which naturally contains germacranolide parthenolide, 3-B-hydroxyparthenolide, seco-tanaparthenolide, canin, and artecanin.
