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.

Why does St John’s Wort interact with so many medicines?

St John’s Wort may alter enzymes and transport proteins used by the body to process medicines.
