Potential Differential Field Symptoms Vs Rubrics

Prof (Dr) Chandrashekhar Goupale

Conceptual Image – Repertorial Totality = Potential Differential Field

Potential difference is that symptomatology which remains after deduction of repertorial totality from the conceptual image.

A Homoeopathic physician collect the all data and facts of case from patient, attendants and from his own observations.

By logical arrangement of all the signs and symptoms he makes the conceptual image of the diseases.

Conceptual image is the totality of the case in which important symptoms are arranged according to their hierarchy.

This totality helps us to select the right medicine from our Materia medica.

After that physician rearrange/modified the totality according to repertory used and method used for repertorisation.

For example, if Kent repertory used then arrangement will be

  • Mental general
  • Physical general
  • Characteristics particulars

If BTPB used then arrangement will be (according to modern method)

  • Causative modalities
  • General modalities
  • Physical generals
  • Concomitants
  • Mental for reference

Modified totality as per the repertory used is called as reportorial totality

  • Repertorial totality is also known as repertorial syndrome.
  • While rearrangement of totality according to the repertory some symptoms may remain because they do not fit into selected repertory.
  • The symptoms which remains are known as potential difference field
  • PDF usually consists of finer general symptoms such as thermals, modalities, desire & aversion, physical constitution etc.


  • It Helps to select one medicine from group of medicine that comes after repertorisation.
  • Ultimately helps for individualizing the case.
