St Johns Wort Health Benefits and Information
Native to Europe, St. John's wort is now found growing in dry areas such as the edges of fields and along roadsides in many temperate climates throughout the world. It is a shrub-like weed that spreads rapidly and invades cultivated land unless controlled. St. John's wort blooms from late May through September, depending on the climate. It was believed to bloom on the birth day of St. John the Baptist, June 24 - hence the name St. John's wort.
St. John's wort is believed to support healthy moods. Many people taking St. John's wort show an improvement in mood and ability to carry out their daily lives.
The major active ingredients in St. John's wort include hypericin and other dianthrones, flavonoids, xanthones, and hyperforin. For many years researchers believed the benefits of St. John's wort were a result of its hypericin contnet and the inhibition of the enzyme monoamine oxidase, however, more recent research suggests that its antidepressant actions may be a result of other active constituents, such as hyperforin, and flavonoids.
