St Johns Wort

Hypericum perforatum


Once used by Ancient Greeks and Romans to ward off evil spirits, St John’s Wort is used today as a natural anti-depressant, a gentle alternative to conventional medications and with far fewer side effects. An analysis of studies of St John’s wort revealed that the herb is as effective as regular anti-depressant drugs in the treatment of depression that is mild to moderate.

Parts used

Herbal supplements are made from the dried flowers of the plant, which is a shrubby perennial with bright yellow blooms.


The flowers contain a number of therapeutic substances, including a healing pigment called hypericin.
