About Topas

A European-bred medicinal selection of Hypericum perforatum noted for high, comparatively stable production of hypericin and flavonoids such as hyperoside and rutoside; historically among the most widely cultivated commercial St. John's Wort varieties. It closely resembles the wild species in appearance but is distinguished by its elevated content of the active medicinal naphthodianthrones.
