[Regulative therapy: treatment with nonspecific stimulants in dermatology in traditional and modern perspectives].

Stimulation or regulation therapies are old therapeutic procedures based on models reaching back to traditional medical faculties in ancient times and in the Middle Ages. Among this heterogeneous group are acupuncture, purgative procedures (especially the Aschner methods), autohemotherapy, fasting therapy, homeopathy, microbiological and physical therapies. The basic principle underlying all of these procedures is that stimulants applied in proper doses to the organism elicit counterregulation. The counterregulation stimulates 'self-healing processes' within the organism. The efficacy of stimulation therapies was originally deduced mostly from traditional explanatory models which have lost their relevance for modern medicine. However, it has been found in applications in dermatology that many of these stimulation therapies can lead to clinical improvement in selected indications and that modern explanatory models can be found for these effects. This presentation reports on exemplary applications of stimulation therapies in dermatology. Traditional and modern concepts of action are compared.
