St. John s Wort is a plant with yellow flowers that researchers continue to look at for its health and well being benefits. A perennial herb, it is from Europe and found its way to America with settlers. It is commonplace in meadows and fields. The first recorded use of St. John s Wort was in ancient Greece. It also goes by the following names: hypericum, Klamath weed and goat weed.
For centuries, this plant has found use as a medicine for depression and anxiety. People often used it to treat mental conditions and nerve pain. Today, people use the herb to treat sleep disorders and anxiety as well as a treatment for mild to moderate depression. In Europe, St. John s Wort is available as a prescription medicine and finds wide use there.
In the United States, it is an herbal supplement and does not have classification by the government as a prescription medicine. However, there is great interest in the U.S. in this herb s capabilities as treatment for depression. Studies show St. John s Wort has a minimal effect on major depression. There is evidence though that it is a useful herb for treating milder depression. Some studies show it acts similar to synthetic antidepressants by affecting the neurotransmitters in the brain. There is also evidence that it produces fewer side effects than these synthetics.
In North America, St. John s Wort comes in capsule, tablet, liquid extract, oil based skin lotions and tea form. The flower tops of the plant find use in tea formulations. The major active elements in the herb, considered by some researchers as antidepressants, are hyperforin and hypericin. Studies suggest that the hyperforin in the herb plays a part in helping people decrease alcohol consumption. In addition, hyperforin has beneficial antibacterial properties. The plant also contains essential oils and flavonoids. Native Americans have a history of use of St. John s Wort as an anti inflammatory, antiseptic and astringent agent.
If you decide to try St. John s Wort, you must consult with a health care professional first, as this herb interacts with other medications. Evidence shows that it can affect anticoagulant drugs and contraceptive pills. It can also affect medication needed to treat high blood pressure.
One study of St. John s Wort showed it was beneficial to a group who consumed 300 mg. three times daily compared to a group who took a placebo only. This study occurred over a four week period. Sixty seven percent of the St. John s Wort group experienced improvement of their depression compared to 28 percent of the placebo group. This study included only those suffering from mild depression. What was important in this study was that there were no adverse side effects from the St. John s Wort as compared to synthetic antidepressants. This was significant because many patients often refuse standard antidepressants because of the harmful and bothersome side effects they produce.
There is no denying that St. John s Wort has a long tradition as a medicine to treat anxiety and depression. This is why studies continue into its effectiveness. Researchers do not want to ignore repeated testimonials about the herb s antidepressant capabilities; they seek to make sure these claims are legitimate by having facts to back them up.
Thirty seven trials that met criteria for being credible received recognition concerning St. John s Wort. They received summarization in a study. (Cochrane Database of Systematic Reviews 1998, Issue 4. Art. No.: CD000448. DOI: 10.1002/14651858.CD000448.pub2.)
The conclusion reached upon analysis of the studies showed St. John s Wort could benefit those with milder types of depression. No conclusive evidence exists that more severe types receive anything more than minimum benefits from the St. John s Wort products that were part of the studies. The researchers stress that their analysis applies only to certain products they tested, not every St. Johns Wort formulation on the market. Many are of different pharmaceutical quality and of different strengths and purities.
Research will continue into this natural product that the earth provides us. At the very least, St. John s Wort does help some forms of depression. The jury is out on whether its benefits will extend to those who suffer harsher forms of the debilitating mental condition that affects millions.
