Passion flower, an herbaceous vine with trilobed leaves, has been used by Native American for hundreds of years. Nature's Plus Herbal Actives Passion flower extract is uniformly standardized to a minimum of 3.5-4% (8.75-10 mg) flavonoids, calculated as isovitexin 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 flower, which naturally contains glycosides and harmane alkaloids (passiflorine, aribine, loturine and yageine).
