Classical versus non-classical homeopathy

Hahnemann's formulation of homeopathy is often referred to as classical homeopathy. Classical homeopaths take a detailed patient history, often lasting more than one hour, base their prescription also on incidental or constitutional symptoms, and administer one remedy at a time at infrequent intervals (typically, not more than once a month).

By contrast, clinical or non-classical homeopathy treatments can involve more than one remedy at a time. For example, some multi-remedy homeopathic formulations are marketed for specific medical conditions. Some formulations use a 'shotgun' approach of the most commonly indicated single remedies in mixture form. Other formulations are proprietary mixtures marketed for specific diagnostic criteria.
