The blood-red juice that exudes from its stems has made it a focus for
much myth and ritual. The herb's common name comes from its traditional
harvesting on St John's day, 24th June. The genus name Hypericum is
derived from the Greek words hyper (above) and eikon (picture), in
reference to the plant's traditional use in warding off evil by hanging
plants over a religious icon in the house during St John's day. The
species name perforatum refers to the presence of small oil glands in
the leaves that look like windows, which can be seen when they are held
against the light.
