Review of Ernst (2002) In 2002, Professor Edzard Ernst, Complementary Medicine first professor at Britain's University, made the first systematic review. Cinergy Health of all the studies he could find in any language, on the effectiveness of Bach flower. Removing them from six databases, found 56 of them were only four in which some form of control would allow scientific evaluation, alongside others whose lack of rigor or whose character made them useless for such assessment. The rest (52) were not oriented accurately to the flowers of Bach, or lacked sufficient clinical control. Ernst's work presents the results of the synthesis of these 4 trials available at the time of its preparation (2002).In such studies, 'two trials suggest a positive outcome, "but" those studies that controlled for the placebo effect and minimized the randomizing selection bias, showed no effects beyond a placebo response. Ernst concludes that "the hypothesis that flower remedies are associated with effects beyond a placebo response is not based on rigorous clinical trial data. Below the four studies are discussed. The Center for Reviews and Dissemination (CRD) British published a commentary on the review by Ernst in which, while appreciated the breadth of the search for studies and selection methodology, which is put together critical studies involving "individualized medicine" to the time a standard remedy, and the inclusion of healthy participants.Although "the author's goal was to critically evaluate research on flower remedies ... scarcity of data in the review indicates the need for more research to obtain a more conclusive" on the effectiveness of flowers Bach. Although study quality was rated good 'aspects of the review process ... were conducted by one author, and this may have introduced a bias in the review. Ernst results seem to support their conclusions, but "it does not guarantee its assertion that flower remedies are not clinically different from placebos. Therefore, "it takes more skill-based tests of placebo control in order to clarify the effect of flower remedies in various clinical areas.Methodologically, a problem common to studies that seek to confirm the effectiveness of spiritual therapies, which his supporters deny the legitimacy of isolating problems and standardize methods, citing an obligation to individualize each treatment. That renders any objective assessment, when all cases are unique and impossible to classify. But, say both the value of the remedies, without assigning virtue to the act itself unique therapeutic relationship between therapist and patient. In fact scientific critics of such therapies generally deny specific value and the proclaimed objective of the remedies, leaving aside questions of faith and "vibrations". The problem of working with insoluble elements is also healthy because it deviates from the protocols, but it's the kind of person who mainly uses these therapies. Bach flower remedies, in particular, are set for emotional disorders are not usually considered a clinical medical condition.Referring to the above, note that one of the four studies reviewed by Professor Ernst is a previously published article (1999) by him in collaboration with Dr. N. Armstrong. This was a 1998 study by the Department of Complementary Medicine at the University of Exeter, where Ernst is professor, to "examine the efficacy of Rescue Remedy (Rescue Remedy) in the" anxiety due to exams' in healthy college students. The study results suggest that participants who took the flower remedy had no less anxiety about the situation of examination participants who took placebo, concluding that "this study provides no evidence of the effectiveness of Rescue Remedy under the experimental conditions given ' . The study was carried out carefully, using a standard chart to measure anxiety, with random selection of participants and double blind. The only weak point was that of the 100 students initially enrolled, only 45 completed the study.Obviously, the conclusions of previous studies, like those of other clinical trials, apply in varying degrees specifically examined treatment, rescue remedy for anxiety in healthy students, and family treatment, Bach flowers, which share the same theoretical and methodological foundations.
