Effects of additional agitation process on the spectrophotometric profiles of homeopathic high dilutions

INTRODUCTION: Conventional homeopathy advocates giving 10 strokes (agitation/succussions) to a prescription bottle containing liquid dilution, before taking it. To scientifically support such activity, it must be based on studies on the physicochemical aspects of the memory of water and agitated water chains, supplemented with spectrometry. OBJECTIVE: To analyze spectrometric profiles of homeopathic high dilutions, comparing additionally agitated and non-agitated dilutions, and to define differences according to each dilution´s kingdom. METHODOLOGY: Homeopathic dilutions were prepared using a ratio of 1:100 obtaining dilutions from 1cH to 15cH. Measurements of absorbance of 15cH dilutions were performed at 340 nm and 200 nm, with and without additional agitation. RESULTS: Statistically significant differences were found between agitated and non-agitated dilutions (p <0.05) for Apis mellifica, Bufo rana, and Calcium iodatum, with a decrease in the mean value of absorbance (340 nm) in agitated solutions. For A nica montana, Matricaria chamomilla, Coffea arabica, Pulsatilla nigricans, Calcium iodatum and Natrum muriaticum, the absorbance values increased; these values decreased for Apis and Bufo. In addition, measurements were performed with a shorter wavelength (200 nm); it was observed that there are significant differences for all homeopathic dilutions studied. Additionally, when comparing the mean values of the absorbance for each kingdom, and observing the agitation factor, a statistically significant difference was found in the animal kingdom (p<0.05), having lower absorbance for agitated dilutions. CONCLUSION: Comparisons of the spectrometric profiles of agitated and non-agitated solutions allow to observe that there is a difference of the absorbance when comparing a previously agitated solution and a solution with no agitation before taking it.

La primera parte de este artículo se dedicó a presentar las líneas de investigación biológica experimental que se realizan en la Homeopatía; ahora, esta segunda entrega se enfoca, de inicio, en la presentación y el análisis de 25 estudios de notable calidad metodológica que permiten evaluar científicamente la eficacia clínica de la medicina hahnemanniana. Cabe decir que a pesar de que la realización de estos trabajos es complicada y de que sus resultados varían, en conjunto nos ayudan a concluir que “no es tan fácil afirmar, como una simple visión general, que la Homeopatía es un placebo”. A continuación, el doctor Bernard Poitevin enlista las hipótesis que distintos grupos de científicos han tratado de corroborar o desmentir para dar respuesta a una de las interrogantes más frecuentes que se le plantean a la Homeopatía: cuál es el mecanismo de acción del medicamento homeopático (y, en consecuencia, qué tipo de información tiene y de qué manera interactúa con el organismo del paciente). Los resultados obtenidos hasta ahora no son concluyentes, ya que este tipo de investigaciones son todavía muy recientes. Finalmente, el autor nos recuerda que la Homeopatía es una disciplina evolutiva y, como tal, debe eludir los dogmatismos e incluso cuestionar sus principios fundamentales cuando sea necesario. Sólo a través de la investigación a fondo de aquellos problemas científicos que plantea la Homeopatía será posible acallar las críticas y, sobre todo, se tendrá un mejor conocimiento de esta disciplina médica, lo que en consecuencia mejorará su aplicación y efectividad...

The first part of this paper was dedicated to show the lines of experimental biological research being conducted in homeopathy; now, this second part focuses, at first, to the presentation and analysis of 25 studies of high methodological quality that allows to evaluate scientifically the clinical efficacy of Hahnemann’s medicine. We can say that although the realization of these studies is complicated and that their results may vary, together they help us to conclude that “it is not so easy to say, as a simple overview that homeopathy is a placebo”. Then Dr. Bernard Poitevin lists the hypothesis that different groups of scientists have tried to corroborate or deny to answer one of the most frequent questions posed to homeopathy: what is the mechanism of action of homeopathic medicine (and therefore what type of information does it has and how it interacts with the patient’s body). The results so far are inconclusive, since this type of research is still very recent. Finally, the author reminds us that homeopathy is an evolving discipline and, as such, must avoid dogmatism and even to question its fundamental principles when necessary. Only through a profound research of those scientific problems that Homeopathy propose It will be possible to silence criticism and, above all, we will have a better knowledge of this medical discipline, which consequently will improve its implementation and effectiveness...

La Homeopatía se fundó sobre un método que es, al mismo tiempo, experimental y empírico. La Homeopatía es parcialmente experimental debido a que su semiología nació con la experimentación sobre el hombre sano, efectuada según el método hahnemanniano; asimismo, es parcialmente empírica porque se basa en el trabajo de observación de los médicos homeópatas y en la adquisición de la experiencia práctica, la cual ha sido transmitida a alumnos deseosos de utilizar este método terapéutico. La investigación en Homeopatía se ha desarrollado progresivamente, tratando de integrar las aportaciones de estos dos métodos: experimental y empírico. De hecho, los esfuerzos realizados por situar a la Homeopatía dentro de una metodología rigurosa se remontan al inicio mismo de esta disciplina, inscrita desde su origen por Hahnemann dentro de la línea científica y médica original...

Homeopathy is in part experimental because the semiology was born with the experimentation on the healthy man, which was performed according to Hahnemann´s method; it is also partly empirical because much work is based on the observation of homeopaths and the acquisition of practical experience, which has been transmitted to students eager to use this therapeutic method. Research in Homeopathy has been gradually developed, trying to integrate the contributions of these two methods: experimental and empirical. In fact, efforts have been made to place homeopathy within a rigorous methodology dating back to the beginning of the discipline itself, from its origin registered by Hahnemann within the original scientific and medical field...
