St. John's Wort History

From an ancient protective charm to a modern therapeutic herb, Hypericum perforatum has carried cultural and medicinal significance for centuries.

The plant's common name comes from its habit of blooming around the summer solstice and St. John's Day (June 24), the feast of St. John the Baptist. "Wort" is simply the Old English word for a plant or herb.

Because it flowers near midsummer, the plant became tied to St. John's Day and came to symbolize light, warmth and the turning of the season.

Protection against evil

In medieval Europe it was hung above doorways and windows as a charm to ward off witches, demons and evil spirits.

Magic and ritual

It featured in charms for good fortune and in folk rituals, and its reputation as a healing plant spread through Greek and Roman medicine as well.
