A perennial native to Britain and other European countries and Asia, St. John's Wort has spread throughout the Eastern United States and Canada. Nature's Plus Herbal Actives St. John's Wort flower extract is uniformly standardized to a minimum of 0.3-0.5% (750 mcg-1250 mcg) hypericin 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 flavonoids, tannins, xanthrones, monoterpenes and phytosterols.
