St. John’s Wort is an important herb for the nervous system. It has long been popular for supporting this system. St. John’s Wort contains at least 10 pharmacologically active constituents. Numerous studies show that one of these, hypericin, appears to act by elevating mood and acting as a mild calmative. Recent scientific studies have shown that another constituent, hyperforin, may have more powerful mood-enhancing, spirit-lifting properties. A randomized, double-blind, placebo-controlled study published in 1998 showed that patients who received the highest amounts of hyperforin-containing St. John’s Wort scored highest on the Hamilton Rating Scale for Depression. (A high score on the rating scale indicates lower levels of depression.) NSP St. John’s Wort also contains passionflower, an herb with a long history of nervous system support. Each capsule contains 300 mg St. John’s wort standardized to 0.3% hypericin.
