The historical development of homeopathy was not an evolution according to Hahnemann's intentions. Even during his lifetime, some homeopathic doctors considered symptoms as the key to solving the case. This finally led to what we can describe now as 'Kentian' homeopathy, named after the main representative of this symptom orientated homeopathy. The 'rise and fall' of homeopathy is mainly based on and the consequence of this so-called symptom-based or Kentian homeopathy. However, Hahnemann did not introduce a symptom-based form of homeopathy but a disease-based form, based on recognizing miasms as the main basis for chronic disease.
