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.
