Herbalists now know that the flowers of the plant called St. John's Wort, used for centuries to heal wounds, contain hypericin, a substance with germicidal, anti-inflammatory and antidepressant properties. These blooms also hold high concentrations of chemicals known as flavonoids, which are thought to boost the immune system. The plant (wort means "plant" in Old English) was named for St. John the Baptist, because its blood-red flowers are said to bloom on the anniversary of his execution. A woody perennial, its leaves are dotted with glands that produce a red oil when pinched.
