The article concerns the problem of small doses. We study the solutions of caffeine in a wide concentration range, including ultra-small concentrations. It turns out the possibility of manifestation of the effects of ultra-low doses for a solution to-caffeine, these solutions are investigated by ultraviolet spectroscopy, prepared as a water and alcohol in the solvent, the results are compared.
