The flowering herb contains naturally occurring hypericin, pseudohypericin, flavonoids, phenolic compounds and other plant constituents.

The hypericins level is used as a marker of extract strength and consistency. It does not determine suitability by itself, and a higher-hypericin product is not automatically more appropriate.

This regular St John’s Wort 1:2 extract should not be confused with MediHerb St John’s Wort High Grade 1:2, which contains a higher declared hypericins level and a different ethanol concentration.

St John’s Wort may reduce the effectiveness or change the blood concentration of certain medicines by affecting drug-metabolising enzymes and transport proteins.
