As a tissue restorative for nerves, St. John's Wort is indicated for stroke patients, for mild neuroses, sleepwalkers, and accident victims.
St. John's wort has been known as goatweed, klamath weed and tipton weed. It has a rich folkloric tradition and a history of use that began with the ancient Greeks and has continued to the present. It grows and is used throughout Europe, North America and elsewhere. It has been celebrated for its magical qualities and blasted as a "noxious weed."
St. John's wort has a pale brown stem and oblong leaves that grow in pairs. The leaves contain many translucent oil glands that look like holes. The bright red color in these glands is produced by the pigment hypericin.
The plant produces clusters of yellow flowers from June to September. Each of these flowers has five petals with black dots at the edges. These petals produce the same dark red pigment, hypericin, which is regarded as the key constituent in St. John's Wort, though there are dozens of other active constituents. Hypericin may be found throughout the plant, but is typically found in greatest concentration in the yellow flowers. Hypericin concentration is typically highest when the flower buds are full but not quite open.
APPLICATIONS
