St John's Wort contains the naphthodianthrones hypericin and pseudohypericin (hypericins), flavonoids, phenolics and other compounds. St John's Wort 1:2 contains a minimum of 0.2 mg/mL of hypericins to ensure optimal strength and quality.

St John's Wort Quality Story

St John's Wort is comprised of a wide range of phytochemicals of which the naphthodianthrones (consisting mainly of hypericin and pseudohypericin) are characteristic, while several other constituents are found across a very wide variety of plant species; e.g., chlorogenic acid, flavonoids and biapigenins. Studies have shown that hypericin administered with flavonoid glycosides caused an increase in the bioavailability of hypericin. St John's Wort extracts containing the flavonoid glycosides but devoid of hypericin and hyperforin have been shown to be pharmacologically active in model systems. Additionally, extracts devoid of hyperforin have been proven effective in clinical trials as have extracts containing hyperforin. In the graph, all extracts contained the same level of napthodianthrones (hypericins), however a wide range of variation was shown for the other constituents when analyzed by HPLC, some extracts having very low levels of all the phytochemicals you would expect in a good quality extract of Hypericum perforatum. MediHerb recognizes the importance of all the other constituents, particularly the oligomeric procyanidins and flavonoids and tests all it's products using the techniques which allow the identification of these components.
