The main aim of the study is to determine whether a homeopathic drug in the potency C12 provokes more characteristic homeopathic proving symptoms after three weeks compared to a placebo in healthy volunteers.

Secondary aims are to develop and to test a qualitative analysis methodology on which to base a definition for drug-specific (characteristic) symptoms and to compile a profile of characteristic homeopathic proving symptoms of the drug being trialled for therapeutic purposes.

This study protocol adapts the traditional homeopathic drug proving methodology to a modern clinical trial design.

Arms Assigned Interventions
Experimental: Homeopathic drug, potency C12 Drug: Homeopathic drug C12
Subjects in the intervention group are instructed to take five globules of the trial drug (potency C12), five times per day for a maximum of five days (5×5×5). The study medication is obtained from DHU (Germany), produced according to the Hahnemannian method. Subjects are asked to stop taking the medication, in agreement with their investigator, if they experience any of a predefined set of proving symptoms
Placebo Comparator: Placebo Other: Placebo
Placebo consists of pure sucrose globules (DHU, Germany) that are not potentiated nor impregnated with alcohol. The administration scheme is identical in the placebo control group to that of the intervention group.
