Here is a thorough overview of the topic:
Repertory - Introduction, Definition, Types & Kent's 37 Chapters
1. Introduction to Repertory
The word "Repertory" is derived from the Latin word "Repertorium" meaning an index or a list. In homeopathy, a repertory is an indispensable tool that helps the physician find the most suitable remedy (simillimum) for a patient by systematically indexing symptoms from the Materia Medica.
The first homeopathic repertory was compiled by Dr. Hahnemann himself (Fragmenta de Viribus, 1805). Since then, repertories have evolved significantly. Among all repertories, Kent's Repertory of the Homoeopathic Materia Medica by Dr. James Tyler Kent (1849-1916) remains the most widely used, universally accepted, and influential repertory - the "pole star" of homeopathic repertorization.
2. Definition of Repertory
"A repertory is an index of symptoms of Materia Medica arranged in a systematic order to facilitate the selection of the simillimum."
Other important definitions:
- Calvin B. Knerr: "A repertory is a book of reference in which the symptoms of medicines are classified and arranged for the purpose of convenient reference."
- Dr. Kent: A repertory is a tool for working out cases using symptoms and finding the remedy that covers all characteristics of the patient.
- In simple terms: Repertory = Index of Materia Medica arranged symptom-wise
The relationship between Materia Medica and Repertory is:
- Materia Medica = Drug-based arrangement (remedy-to-symptom)
- Repertory = Symptom-based arrangement (symptom-to-remedy)
3. Types of Repertory
Repertories are classified based on plan of construction, arrangement, and author:
A. Based on Plan/Arrangement
| Type | Description | Example |
|---|
| Schema / Complete Repertory | Covers all symptoms from head to foot (anatomical/regional) | Kent's Repertory |
| Pathological / Clinical Repertory | Arranged based on diseases/clinical conditions | Knerr's Repertory |
| Therapeutic Repertory | Arranged based on therapeutic use | Boericke's Repertory |
| General Repertory | Covers generals and modalities | Boenninghausen's TPB |
| Partial Repertory | Covers a specific organ or part only | Phatak's Repertory (partially) |
B. Based on Author / Historical Classification
| Repertory | Author | Year | Key Feature |
|---|
| Fragmenta de Viribus | Hahnemann | 1805 | First ever homeopathic repertory |
| Therapeutic Pocket Book (TPB) | Boenninghausen | 1846 | Based on totality of symptoms; generals-based |
| Knerr's Repertory | Knerr | 1896 | Based on Hering's Guiding Symptoms |
| Kent's Repertory | J.T. Kent | 1897 | Most widely used; logico-utilitarian |
| Boger-Boenninghausen's (BBCR) | Boger | 1905 | Combines Kent + Boenninghausen approach |
| Phatak's Repertory | S.R. Phatak | 1963 | Concise, for busy practitioners |

| Complete Repertory | Roger van Zandvoort | 1992 | Most comprehensive computerized repertory |
C. Based on Logic Used
- Inductive Repertory - Boenninghausen's TPB (particulars lead to generals)
- Deductive / Logico-Utilitarian Repertory - Kent's Repertory (generals to particulars)

5. The 37 Chapters of Kent's Repertory (In Proper Order)

7. Arrangement Logic of Chapters
The chapter sequence follows Hahnemann's order - starting from the highest (mental/emotional) symptoms and progressing downward:
- Mind and Sensorium (Chapters 1-2): Mind, Vertigo
- Head and Sense Organs (Chapters 3-13): Head → Eye → Vision → Ear → Hearing → Nose → Face → Mouth → Teeth → Throat → External Throat
- Digestive System (Chapters 14-17): Stomach → Abdomen → Rectum → Stool

- Reproductive System (Chapters 23-24): Male Genitalia → Female Genitalia
- Respiratory System (Chapters 25-28): Larynx & Trachea → Respiration → Cough → Expectoration
- Thorax & Spine (Chapters 29-30): Chest → Back
- Limbs (Chapter 31): Extremities
- General Physiology (Chapters 32-37): Sleep → Chill → Fever → Perspiration → Skin → Generalities
Key memory tip for the chapter order:
"Mind-Vertigo-Head, Eye-Vision-Ear-Hearing, Nose-Face-Mouth-Teeth, Throat-Ext.Throat, Stomach-Abdomen-Rectum-Stool, Bladder-Kidney-Prostate-Urethra-Urine, Male-Female, Larynx-Respiration-Cough-Expectoration, Chest-Back-Extremities, Sleep-Chill-Fever-Perspiration-Skin-Generalities"
This covers all 37 chapters in their correct sequence as published in Kent's Repertory of the Homoeopathic Materia Medica.
