ABSTRACT
Clearly, our general physical, biological, and chemical theories provide no reason to believe that homeopathy has any effect whatsoever. Conversely, if we were to accept the theories behind homeopathy, we would need to reject or at least revise a large number of established physical and chemical theories. In addition, homeopathy has been evaluated rigorously by randomized controlled trials, and the research has been examined in meta-analyses. Some trials have shown that there might actually be some effect of homeopathy, but it has been widely discussed what to conclude from this. The conducted studies have overall been of a poor quality, and it is likely that some will produce misleading results. The overall conclusion in the established research community has been that there are no clinical effects of homeopathy apart from placebo effects, if any such are found (Shang et al., 2005).
