After the discovery of “Law of Similiars” with Cinchona bark, Dr.Hahnemann started proving different drugs on him and also on different healthy human beings, reproving the existing drugs to get the fuller account of the positive effect of drugs. By this he collected a large number of symptoms in every drug. All these symptoms were explained in books like “Materia Medica Pura” and “Chronic Diseases”.

    During Hahnemann’s time many drugs were proved. As remedies and proving multiplied it became a problem to keep track of all the symptoms, and Master Hahnemann himself consciously felt the need for indexing this growing pool of information. Hahnemann realized the limitations of human mind to remember all symptoms and felt the need for an aid to retrieve the facts.

    He demonstrated the procedure by working on cases in Materia Medica Pura, which gave some idea about his concept on which repertorization stands today. He wrote in Materia Medica Pura that for the convenience of treatment, we require to write down all remedies producing a symptom along with the circumstances under which they occur expressing the remedies in short with few letters and proceed in same way to be able to perceive the remedy sought for which covers homeopathically all the symptoms especially characteristic totality. Thus was born the concept of repertory and repertorization.
