St. John's Wort Extract Reviews:
St. John's wort has been esteemed as medicine for centuries, and ancient Europeans believed it had magical protective powers against disease and evil. Native to Europe, Asia and northern Africa, the yellow flowers are now a common midsummer sight throughout North America. St. John's wort grows particularly well in northern California and southern Oregon, where ranchers considered it a pest because it can be toxic to livestock (see Safety). Beetles released as a biological control have vastly reduced plant populations in areas of former abundance.
St. John's Wort Extract Benefits:
St. John's wort achieved instant fame in the US when clinical studies confirmed its effectiveness in the treatment of mild-to-moderate depression. The news came as no surprise to herbalists, who have long used St. John's wort not only for depression, but also for the treatment of wounds, burns, injured nerves, inflammations, ulcers, anxiety, and other ailments. Today, St. John's wort is one of the most frequently used treatments for mild-to-moderate depression in Germany, and it seems destined to become just as popular in the US. The plant has also generated intense scientific interest because of its potential as an antiviral agent.
Main Benefit:
Internal: Anti-Depression, Anti-Anxiety.
External: Good for Wounds, Bruises and Burns.
St. John's wort extracts and oil infusions are both made from the fresh flowering tops of the herb. Hypericin is the compound in St. John's wort that gives good quality extracts and oils their characteristic vivid red color, and fresh flower buds have the highest hypericin content.
St. John's wort extracts are taken internally (for example, for depression), and the oil is for external use. Extracts are available in the form of tinctures, tablets and capsules. Most of the clinical trials on depression utilized St. John's wort extract standardized to 0.3% hypericin. (Standardization ensures that an extract contains a consistent level of a constituent, such as hypericin.) Unstandardized St. John's wort extracts have been used traditionally, but there has been little or no clinical research to assess their effectiveness.
