We prepare our St. John's Wort Extract from fresh (undried) flowering & budding tops of Hypericum perforatum plants which are Custom Wildcrafted in their natural wild habitat.To assure optimal extraction of hypericin and flavonoids (rutin quercitrin isoquercitrin and quercetin) we hand-harvest only the uppermost flowering & budding tops which are then taken directly to our laboratory and promptly extracted while still fresh and succulent.Other products from HerbsPro
