A homoeopathic drug proving of Withania somnifera 30CH
Introduction The purpose of this study was to conduct a homoeopathic proving of Withania somnifera in the thirtieth centesimal potency [30CH], thereafter to determine and report the symptomatology in standard materia medica and repertory format, and then compare this symptomatology to the indigenous African and Ayurvedic medicinal usage of Withania somnifera. Methodology The homoeopathic drug proving of Withania somnifera 30CH was conducted as a randomised, double-blind, placebo-controlled trial at the Durban University of Technology. The intervention, Withania somnifera 30CH, was manufactured according to methods 6, 8a and 10 of the German Homoeopathic Pharmacopoeia [GHP] (Driehsen, 2003). Thirty healthy subjects were recruited as provers after meeting with the inclusion criteria (see Appendix A). The provers were randomised into two groups: 80% of provers received verum and 20% received a placebo control identical in appearance to the verum. The vehicle for both verum and control was six lactose powders, self-administered sublingually three times daily by all provers over two consecutive days. The measurement of proving symptoms was two-fold: a subjective account of symptoms produced by the verum/placebo recorded daily in a journal provided, and objective monitoring by the researcher. After the proving-generated symptoms had subsided, journals were collected and data analysis commenced. The accepted symptoms were collated and reported in standard materia medica and repertory format. Results The proving of Withania somnifera 30CH produced a total of 282 rubrics, five of which were newly formulated rubrics. There were 184 Grade 1 rubrics, 98 Grade 2 rubrics and 0 Grade 3 rubrics. The majority of rubrics were represented in the MIND, DREAMS, HEAD and GENERALS sections of the repertory. Analysis of results provided insight into the similarities and differences between indigenous African and Ayurvedic medicinal usage of Withania somnifera and the relationship to other homoeopathic medicines. Conclusion Clearly observable symptomatology was produced by healthy provers in response to the administration of Withania somnifera 30CH. In addition, there was significant correlation between the proving symptomatology and the indigenous African and Ayurvedic medicinal usage of Withania somnifera.
