Here is a detailed explanation of all 8 Steps of Repertorization as per standard homeopathic curriculum:
Steps of Repertorization
Step 1 - Case Taking
This is the foundation of the entire repertorization process. A case is taken according to Hahnemann's instructions in Organon of Medicine (§83-104).
What is collected:
- Chief complaint - onset, duration, character, location, extension
- Modalities - < (aggravation) and > (amelioration) from time, temperature, weather, position, food, motion, sleep, etc.
- Concomitants - symptoms occurring alongside the chief complaint that appear unrelated but are consistent
- Mental and emotional symptoms - fears, grief, anger, anxiety, desires, aversions, dreams
- Physical generals - thermals, thirst, appetite, bowels, sleep, sweat
- Past history / Family history
- Causation (Aetiology) - e.g., ailments after grief, fright, exposure to cold, suppression
Types of case taking:
| Type | Used When |
|---|
| Hahnemann's method | Detailed chronic case; physician is silent and lets patient speak |
| Boenninghausen's method | Emphasis on complete symptoms (SLMC - Seat, Location, Modality, Concomitant) |
| Kent's method | Mental generals first; then physical generals; then particulars |
| Boger's method | Causation, modalities and pathological generals emphasized |
Step 2 - Recording and Interpretation
After case taking, the raw information is written down systematically and then interpreted.
Recording includes:
- Patient's own words (verbatim notes)
- Physician's clinical observations (objective symptoms)
- All information arranged under appropriate headings (mental, generals, particulars)
Interpretation means:
- Understanding what the patient actually means when they describe symptoms in their own language
- Converting vague descriptions into precise symptom language
- For example: "I feel worse when the weather changes" → interpreted as aggravation from change of weather
- Differentiating pathological symptoms (common to disease) from individual symptoms (peculiar to the patient)
Important distinction:
- The patient says: "I feel a burning sensation in my stomach but I want cold drinks"
- Physician interprets: Burning pains - desires cold though pains are burning → a striking concomitant/SRP
Step 3 - Classification and Evaluation of Symptoms
Symptoms are classified by type and then evaluated (graded) by their value for repertorization.
Classification (Types of Symptoms):
| Class | Examples |
|---|
| Mental/Emotional | Anxiety, grief, fear, irritability, sadness |
| Physical Generals | Thermals, thirst, appetite, sleep, sweat, desire/aversion |
| Particular symptoms | Symptoms of individual organs/parts |
| Common symptoms | Symptoms common to all cases of a disease |
| SRP (Strange, Rare, Peculiar) | Symptoms that appear contradictory or uncommon |
| Complete symptoms | Having all 4 components: Location + Sensation + Modality + Concomitant |
Evaluation (Grading by Value):
Kent's grading hierarchy:
- Mental generals (will, intellect, emotions)
- Physical generals (whole body reactions)
- SRP / Peculiar symptoms
- Particular symptoms with strong modalities
- Common/pathological symptoms (lowest value)
Boenninghausen's evaluation:
- Emphasizes complete symptoms (each symptom with all 4 elements)
- Concomitants carry special importance
- Modalities of generals ranked highest
Why evaluation matters: If a common symptom (e.g., headache) is given equal weight to a peculiar general (e.g., craving for salt), the repertorization will yield an inaccurate result.
Step 4 - Defining the Problem
This step answers Hahnemann's fundamental question from §3 Organon:
"What is to be cured in diseases?"
The physician must clearly identify:
- What is the disease picture - the totality of the patient's suffering
- What is peculiar to this patient vs. what is common to the disease
- The miasmatic background (psora, sycosis, syphilis) underlying the case
- Whether the case is acute or chronic (determines depth of case taking)
- Obstacles to cure - maintaining causes, lifestyle factors, suppressions
- Centre of gravity of the case - the one thing around which all symptoms revolve (the "essence")
This step requires clinical judgment and philosophical understanding. Without properly defining the problem, even a perfectly executed repertorization will point to the wrong remedy.
Example:
In a case with 20 symptoms, the physician must decide:
- Is this primarily a mental/emotional case (grief-based)?
- Is this a one-sided case (very few symptoms)?
- Is it an acute flare of a chronic miasm?
Step 5 - Erecting the Totality of Symptoms
The totality is not simply a list of all symptoms - it is the carefully constructed, characteristic symptom picture that represents the patient as a whole.
Hahnemann (§7): The totality of symptoms is the "outwardly reflected image of the inner nature of the disease."
What goes into the totality:
- The most characteristic, individualizing symptoms
- Symptoms that are peculiar, rare, or striking
- Symptoms with strong modalities
- The generals + the most important particulars
- Miasmatic indicators
What is excluded from the totality:
- Common pathological symptoms (e.g., fever in malaria)
- Symptoms with no modalities or characteristics
- Symptoms that belong only to the disease, not the patient
Constructing the totality - approaches:
| Approach | Priority |
|---|
| Kent's totality | Mental generals → Physical generals → Particulars |
| Boenninghausen's totality | Complete symptoms (SLMC) + Concomitants |
| Boger's totality | Causation + Generals + Pathological generals |
| Hahnemann's characteristic totality | Most peculiar + striking + uncommon symptoms |
Once the totality is built, each symptom in it must be converted into a rubric from the chosen repertory.
Step 6 - Selection of the Proper Repertory
The appropriate repertory is chosen based on the type of symptoms available in the totality.
| Repertory | Best Used When |
|---|
| Kent's Repertory | Mental generals and physical generals are clear; most commonly used |
| Boenninghausen's TTTT (Therapeutic Pocketbook) | Complete symptoms available; strong modalities and concomitants; one-sided cases |
| Boger-Boenninghausen's Repertory (BBCR) | Causation, pathological generals, and modalities are prominent |
| Boericke's Repertory | Pathological/clinical cases; when generals are few |
| Phatak's Repertory | Quick reference; concise clinical practice |
| Synthesis / Complete Repertory | Modern, comprehensive; used in computer-aided repertorization |
Factors guiding selection:
- Nature of the case (acute vs. chronic)
- Dominant symptom type (mental vs. pathological vs. generals)
- Availability of complete vs. incomplete symptoms
- Physician's familiarity with the repertory's structure
Step 7 - Repertorial Result
After selecting rubrics and tabulating, the repertorization gives a numerical result - a table showing remedies ranked by their total coverage of the rubrics.
Two main methods of tabulation:
a) Total Addition (Aggregation) Method
- All rubrics are taken simultaneously
- Marks (grades 1, 2, 3) for each remedy are added across all rubrics
- Remedies with highest total marks and maximum rubric coverage are ranked first
- Used in: Hahnemann's method, Boger's method, computer repertorization
| Remedy | Rubric 1 | Rubric 2 | Rubric 3 | Rubric 4 | Total |
|---|
| Nat-m | 3 | 2 | 3 | 2 | 10 |
| Puls | 2 | 3 | 1 | 3 | 9 |
| Sepia | 1 | 2 | 2 | 3 | 8 |
b) Elimination Method
- The most characteristic symptom (usually a mental general or SRP) is chosen as the eliminating rubric
- Only remedies present under that first rubric are considered further
- Remaining rubrics are used to further narrow down
- Much faster; used in Kent's method
Keynote Method (variant):
- Prescribing based on one or two striking keynote symptoms rather than full repertorization
- Useful in acute cases or when one symptom is overwhelmingly characteristic
The repertorial result gives a short list of 3-6 remedies - these are the candidates for the similimum.
Step 8 - Analysis of Repertorial Result and Prescription
The numerical result is only a guide - final selection is made through careful analysis.
Analysis involves:
- Studying the top remedies in Materia Medica - does the full drug picture match the patient?
- Checking rubric coverage - does the remedy cover the most important rubrics (generals, SRP) rather than just common ones?
- Miasmatic analysis - does the remedy match the patient's miasmatic background?
- Checking for keynotes/essence - does any remedy have a keynote that perfectly fits the patient?
- Eliminating remedies that score high only on common symptoms
- Using the Potential Differential Field (PDF) - symptoms not used in repertorization that help differentiate between two equally-scoring remedies
The Similimum is selected when:
- It covers the maximum number of characteristic rubrics
- Its grade under important rubrics is highest (bold = grade 3)
- Its Materia Medica picture resonates with the patient's constitution
Prescription includes:
- Selection of remedy (the similimum)
- Potency selection - based on sensitivity, vitality, pathology depth (e.g., 30C, 200C, 1M)
- Dose and repetition - based on the case (single dose vs. repeated doses; LM potency in sensitive cases)
- Follow-up plan - assessment of response after 4-6 weeks in chronic cases; Hering's Law of Cure applied
- Second prescription criteria - based on whether there is improvement, relapse, or a new symptom picture
