Here is a complete, well-structured answer on the Medium of Repertory in Homeopathy, covering Comparative and Integrated types with definitions and examples.
Medium of Repertory
Definition of Medium
The medium of repertorisation refers to the repertory (or repertories) used as the vehicle for conducting the exercise of repertorisation. In other words, the repertory acts as the medium through which a physician finds the similimum for a given case.
Depending on the number of repertories used, the medium is classified as:
- Unitary Medium
- Multiple Medium (which is further divided into Comparative and Integrated)
1. Unitary Medium
Definition: Only one repertory is used for the entire case. All the symptoms to be repertorised are located within that single repertory.
- The repertory is selected based on the operating school of philosophy of the case (e.g., Kentian, Boenninghausian).
- All rubrics are found "under one roof."
- Affords the easiest passage through the case.
Example: Using only Kent's Repertory for a case where strong mental and general symptoms are present (Kentian philosophy), and finding all required rubrics within it.
2. Multiple Medium (Cross-Repertorisation)
Definition: More than one repertory is consulted for a given case - either to help in selecting the similimum or to confirm a result obtained from one repertory.
Purpose:
- To highlight the oneness of all repertories in their objective (finding the similimum).
- To select well-represented rubrics from any of the repertories available.
Multiple medium is further divided into:
A. Comparative Medium
Definition: The same set of symptoms are repertorised separately in different repertories, and the results are compared side by side.
Key Features:
- Each symptom/rubric is looked up independently in each repertory chosen.
- The medicines leading in each repertorial result may NOT tally between different repertories.
- It is quite often an academic exercise - used to understand and appreciate the relative value of different repertories for a given case.
- Useful when the operating school of philosophy cannot be determined for the case.
- More time-consuming than unitary medium.
Example:
A patient presents with anxiety, thirst for cold water, and burning pains better by heat. The physician repertorises the same rubrics in:
- Kent's Repertory → gets one result (e.g., Arsenicum album comes up)
- Boenninghausen's Therapeutic Pocket Book → gets another result
- Synthesis Repertory → gets a third result
The physician then compares all three outcomes to understand which remedy is most consistently prominent across different repertories.
B. Integrated Medium
Definition: Different rubrics from the same case are taken from different repertories and combined (integrated) into a single repertorial exercise. It is used when:
- All required rubrics for the case are not found in a single repertory.
- There is no clarity about the operating school of philosophy, or more than one school is indicated.
Structure of Integrated Medium:
| Term | Meaning |
|---|
| Base Repertory | The primary repertory when the operating school of philosophy is unclear |
| Primary Repertory | The repertory that covers the major share of rubrics (when all repertories belong to the same school) |
| Secondary Repertory | Belongs to the same school as the primary but contributes fewer rubrics |
| Accessory Repertory | Belongs to a different school of philosophy; used for rubrics not found elsewhere |
Important Rule: Since grading of medicines differs across repertories, the grading scale of the Primary/Base Repertory is used as the benchmark, and grades from other repertories are converted accordingly.
Example:
A case has both strong generals and strong particulars. The physician uses:
- Synthesis Repertory as the Primary repertory - for generals (e.g., thirst, thermal reaction, food desires)
- Kent's Repertory as the Secondary/Accessory repertory - for particulars (e.g., a specific local symptom not well-covered in Synthesis)
The marks from both are combined into a single chart, with Kent's grades converted to Synthesis scale, to arrive at the final similimum.
Quick Comparison Table
| Feature | Comparative Medium | Integrated Medium |
|---|
| Core idea | Same rubrics repertorised in multiple repertories separately | Different rubrics taken from different repertories and combined |
| Result | Multiple separate results, then compared | One merged/integrated result |
| Purpose | Academic comparison; when school unclear | Practical use; when rubrics are scattered across repertories |
| Time | More time-consuming | Moderately time-consuming |
| Example | Same anxiety rubric looked up in Kent, TPB, and Synthesis separately | Generals from Synthesis + Particulars from Kent, merged into one sheet |
In summary: The medium of repertorisation defines how many and which repertories are used. Unitary medium is simple (one repertory). Multiple medium involves more than one, and is either Comparative (same rubrics in different repertories, results compared) or Integrated (different rubrics from different repertories, combined into one result). The Integrated medium is the most commonly used in clinical practice when cases have diverse symptom types that span different repertorial strengths.
