This paper deals with the so-called "mysterious" Q-potencies, the dilution of a substance according to particular augmentation methods, dating back to Samuel Hahnemann, the founder of homoeopathy. Hahnemann's method consists of a step by step dilution of substances. ⋯ This is the reason why the Q-potency is still a mystery in Hahnemann's casebooks. This article examines the hidden references to the notations referring to the Q-potency and presents preliminary results.
