represents the evidence is suggestive of higher effectiveness rate for St. John’s Wort compared with a placebo, and similar effectiveness against current antidepressant medication with fewer common side effects or less severity in side effects. (Linde, K., et al (2008) Conclusion)
There is a controversy in the data which in one article states it has a higher effective rate on major depression than placebo, yet the article posted by the Journal of the American Medical Association suggests that it has only slightly higher effectiveness on minor depression similar to that of a placebo. The data produced through these trials is inconsistent with the data from the first article using a sample size of 336 patients they found the research did not support the usage of St. John’s Wort for major depression. (Davidson, J., et al (2002) Results)
The third article by BioMed Central was conducted with a double-blind, and placebo-controlled study. The conclusion of this study was consistent with the conclusion found by Linde, K., Berner, MM., & Kriston, L. being that St. John’s Wort was more effective and safer than the placebo, but had similar effectiveness to the current standard medication used for depression. (Kasper, S., et al (2006)

    Biologically, benzodiazepines bind to GABA receptor sites in the brain. GABA is an important inhibitory neurotransmitter that if in excess amounts in the brain or regulated can cause seizures and sleep problems respectively. Previously, scientists have tried medication substitution to anxiolytics, agonist substitution to mimic the effect, or abstain completely. Liebrenz and his team of five scientists suggest that, “patients’ subjective views are of clinical importance because past research indicates that individuals should be presented with a variety of treatment alternatives, rather than simply being informed about what is obtainable or easiest; in addition, this prior research has found interventions to be most beneficial when patients…

    John’s wort benefits claimed. Two studies, one sponsored by the National Center for Complementary and Alternative Medicine (NCCAM), showed that the herb was no more effective than placebo in treating major depression of moderate severity; ironically, the conventional drugs used in the study did not fare any better than placebo, either (LOL). It should also be noted that these two studies did not directly tested St. John’s wort as a treatment for depression, but as a treatment for mood disorder, which has a broader range of symptoms (that include depression). Nevertheless, the two studies were a big setback for St. John’s…

    The Western definition and symptom list for depression, due to the DSM, had planted its roots and gained ground in Japan. “By 2008 sales of Paxil were over one billion dollars per year in Japan” (Watters, E. 2010). What later came out about the these selective serotonin reuptake inhibitors (SSRI)was that these companies were actually hiding results, such that “the drug had an eightfold increase in the risk of suicidality and that only one in ten test subjects showed a positive response that can be attributed to the effect of the SSRI” (Watters, E.…

    Many patients will be prescribed drugs and they will believe that the drugs will work but the patient does not improve because of the actual chemical components of the drug. An article written in an APA magazine says, “Studies have shown that people with mild depression that take antidepressants, do not do significantly better than using placebos” (Smith36).

    Less than one third of individuals who experience psychological distress seek help from a mental health professional (Andrews, Issakidis & Carter, 2001). It has come to my realization that more individuals seek mood regulating medication for temporary relief from their feelings than those who seek therapeutic help to explore the cause of their distress. I am by no means suggesting that medication is the wrong way, medication can be used when there is evidence of a chemical imbalance contributing to such psychological distress. As the world continues to develop and new issues begin to surface, more people should consider taking steps to counseling rather than medication which only helps with a quarter of the issues, if any in some cases. The…
