Abstract: The aim of the study was to find out, whether in a homoeopathic remedy proving in healthy volunteers the symptoms described under placebo would be different from those reported under Belladonna 30C. 46 healthy volunteers were admitted to the study. For 10 weeks they reported daily the symptoms which they observed in a diary, categorizing the symptoms into given categories of location, mode and time, as well as giving other details. As the study was meant to be a pilot study the data was collected in a closed but large enough categorical set of 188 variables. After a placebo run in week the group was split, and in an 8-week crossover each person took Selladonna 30C and placebo for 4 volunteers from placebo, provided the sample is big enough.
