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.
Fuction
1.St John's wort is widely known as an herbal treatment for depression. It is proposed that the mechanism of action of St. John's wort is due to the inhibition of reuptake of certain neurotransmitters.
2.St. John's wort is also being studied for anxiety because, in some studies on depression, people taking St. John's wort also reported an improvement in anxiety.
3.St. John's wort has also been suggested as a possible treatment for OCD because the same medications (antidepressants) are often used for OCD, and because of promising results from a preliminary study. A later study on St. John's wort, however, didn't find it more effective than a placebo for OCD.
