If you've spent any time in homeopathic study groups, online forums, or college corridors, you've almost certainly encountered the debate: which repertory should I use? Kent, Murphy, or Complete Repertory? Ask five homeopaths and you'll receive five different answers, each passionately argued. It's one of the most common questions in the profession, and for good reason: your choice of repertory shapes how you think about cases, how quickly you find rubrics, and ultimately how effectively you prescribe.
The truth is, there's no single "best" repertory. Each of the three major repertories — Kent's Repertory, Murphy's Medical Repertory (MetaRepertory), and the Complete Repertory — was created with a distinct philosophy, structure, and clinical purpose. Understanding those differences is the key to choosing the right tool for your practice, your patients, and your stage of professional development.
Why Your Choice of Repertory Matters
A repertory is far more than a reference book. It's a framework for clinical thinking. The way a repertory organises symptoms, grades remedies, and structures its chapters reflects a particular approach to understanding the patient and finding the similimum. Two practitioners analysing the same case may arrive at different remedy shortlists simply because they used different repertories — not because one is wrong, but because each repertory highlights different facets of the symptom picture.
Some repertories prioritise breadth, capturing the widest possible range of rubrics and remedy entries. Others emphasise precision, including only well-verified additions. Some use 19th-century language faithful to original provings; others translate symptoms into contemporary clinical terminology. These aren't trivial differences. They affect how quickly you can locate a rubric during a consultation, whether you catch a relevant symptom that another source might miss, and how confident you feel in your final analysis.
Kent's Repertory: The Foundation of Modern Repertorisation
History and Background
James Tyler Kent (1849–1916) published his Repertory of the Homoeopathic Materia Medica in 1897, and it remains the most widely taught and universally recognised repertory in homeopathic education. Kent compiled his work from provings, clinical observations, and earlier repertorial sources, organising the material into a systematic structure that reflected his philosophical commitment to Hahnemannian principles.
Structure and Size
Kent's Repertory contains approximately 68,000 rubrics arranged across 37 chapters, beginning with Mind and concluding with Generalities. The chapter order follows a head-to-foot schema for regional symptoms, with systemic chapters positioned at either end. This structure encourages a top-down approach to case analysis: consider the patient's mental state and general characteristics first, then refine with particular and local symptoms.
The grading system uses three tiers:
- Bold (grade 3): Remedies most strongly confirmed by provings and clinical experience
- Italic (grade 2): Remedies well-supported but with less extensive evidence
- Plain (grade 1): Remedies with limited or single-source confirmation
Strengths
- Time-tested reliability: Every rubric has been scrutinised by generations of practitioners
- Universal teaching standard: Nearly every homeopathic college in the world teaches Kent as the primary repertory
- Philosophical coherence: The structure reflects Kent's deductive method, guiding the practitioner from the whole person to the specific symptom
- Foundation for other repertories: Murphy, Complete Repertory, Synthesis, and virtually every modern repertory builds upon Kent's framework
Limitations
- 19th-century language: Terms like "loathing of life," "coryza," and "stitching pain" can feel alien to practitioners trained in modern terminology
- Gaps in clinical rubrics: Certain conditions common in modern practice are understandably absent
- No updates since Kent's death: The original text has not been revised or expanded
- Limited pathological rubrics: Kent's philosophical preference for functional and mental symptoms means some practitioners find it less useful for pathology-heavy cases
Best For
Kent's Repertory is ideal for students learning the fundamentals of repertorisation, classical prescribers who follow a Hahnemannian methodology, and any practitioner who values a time-tested, philosophically consistent framework. If you are learning how to repertorise for the first time, Kent is almost certainly where you should begin.
Murphy's Medical Repertory (MetaRepertory): The Clinician's Companion
History and Background
Dr Robin Murphy ND (1950–2021) was an American naturopathic physician, teacher, and prolific author who devoted over two decades to compiling the MetaRepertory. Murphy's goal was practical: to create a repertory that a busy clinician could use efficiently during consultations without sacrificing depth or accuracy. He drew from Kent, Allen, Hering, Boericke, Knerr, Phatak, and numerous other sources, synthesising their contributions into a unified, clinically oriented work.
Structure and Size
Murphy's MetaRepertory is significantly larger than Kent, containing well over 100,000 rubrics. It retains a chapter-based structure similar to Kent's but reorganises material for clinical accessibility. Related rubrics that might be scattered across multiple chapters in Kent are grouped together in Murphy, reducing the need to search in several places.
The language has been modernised throughout. Clinical conditions, disease rubrics, and modern pathological terms are integrated in ways that Kent's original structure does not accommodate.
Strengths
- Modern, simplified language: Practitioners can search using contemporary clinical terminology without first translating into 19th-century language
- Clinical organisation: Rubrics mirror how practitioners actually think during consultations
- Comprehensive sourcing: Incorporates material from Allen, Hering, Boericke, Knerr, Phatak, and other major sources alongside Kent
- Practical cross-references: Murphy's cross-referencing system is notably clearer than Kent's
- Regular clinical updates: Murphy continued to refine and expand the repertory throughout his career
Limitations
- Less universally taught: Kent remains the default in most academic curricula
- Purist objections: Some classical homeopaths feel that Murphy's reorganisation obscures the philosophical structure Kent intentionally built into his work
- Source verification: Because Murphy compiled from so many sources, some practitioners raise questions about verification standards
Best For
Murphy's MetaRepertory is the repertory of choice for busy clinical practitioners who need speed and clarity, homeopaths who prefer modern language, and practitioners who value broad remedy coverage from multiple historical sources. It's widely considered the most popular clinical repertory in modern practice.
Complete Repertory: The Comprehensive Reference
History and Background
The Complete Repertory was created by Roger van Zandvoort, a Dutch homeopath and researcher, and first published as a digital database in 1996. Van Zandvoort's ambition was monumental: to compile the most comprehensive repertory ever assembled, drawing from every credible source available and meticulously documenting the origin of every addition.
Unlike Kent or Murphy, the Complete Repertory was conceived from the outset as a digital work, making it particularly well-suited to modern repertorisation platforms.
Structure and Size
The Complete Repertory is one of the largest repertories available, containing well over 250,000 rubrics — roughly four times the size of Kent. Its chapter structure is based on Kent's framework but has been massively expanded.
What truly distinguishes the Complete Repertory is its approach to sourcing. Every addition to the base Kent material is documented with its exact origin. This level of provenance is unique among major repertories and invaluable for practitioners and researchers who want to evaluate the reliability of individual entries.
Strengths
- Unmatched comprehensiveness: For rare symptoms, unusual presentations, or obscure remedies, the Complete Repertory often provides entries that other repertories lack
- Source traceability: Practitioners can distinguish between rubric entries backed by multiple provings and those supported by a single clinical observation
- Regular updates: Continues to evolve, incorporating new provings, modern clinical data, and corrections
- Digital optimisation: Works seamlessly with modern repertorisation platforms
Limitations
- Size can overwhelm: With over 250,000 rubrics, a simple symptom search may return dozens of sub-rubrics and hundreds of remedies
- Primarily digital: Most practical as a software tool rather than a physical book
- Compilation risks: Less reliable entries may sit alongside well-verified ones (though source tracking mitigates this)
- Cost: Access typically requires a paid subscription or software licence
Best For
The Complete Repertory is ideal for thorough researchers who want maximum coverage, practitioners working with rare or complex presentations, academic work requiring traceable sources, and experienced homeopaths comfortable navigating large datasets.
Other Notable Repertories Worth Knowing
Boenninghausen's Therapeutic Pocketbook
Rather than listing specific, narrow rubrics, Boenninghausen's system uses broader categories — location, sensation, modality, and concomitant — which are then combined during analysis. This method can be remarkably effective for cases where the patient's symptoms don't fit neatly into Kent's more specific rubric structure.
Synthesis Repertory
Synthesis is an expanded version of Kent created by Frederik Schroyens and used as the primary repertory in RadarOpus software. It retains Kent's DNA while offering broader coverage.
Boger-Boenninghausen Repertory
C.M. Boger built upon Boenninghausen's methodology, creating a repertory that emphasises characteristic symptoms, modalities, and concomitants. Particularly valued by practitioners who follow the Boenninghausen method.
Saine Repertory
Andre Saine's repertory represents a modern effort to create a highly curated, precisely verified collection of rubrics. Rather than maximising size, Saine focuses on reliability.

Which Repertory Is Right for You?
For Students
Start with Kent. There is no substitute for understanding the foundational repertory that underpins virtually every modern work. Learning Kent teaches you not just where to find rubrics but how to think about cases. Once you have a solid grounding, explore Murphy to see how the same clinical material can be organised differently. For a deeper understanding of Kent's structure, dedicated study of the repertory's organisation is well worth the time.
For Classical Prescribers
If you follow a strictly Hahnemannian or Kentian methodology, Kent's Repertory remains your natural home. You might also explore Boenninghausen's Therapeutic Pocketbook as a complementary tool.
For Clinical Practitioners
Murphy's MetaRepertory is hard to beat for daily clinical use. Its modern language, intuitive organisation, and broad sourcing make it the fastest path from patient symptom to relevant rubric.
For Researchers and Thorough Analysts
The Complete Repertory provides the widest net. When you're working with unusual presentations, rare remedies, or academic research that demands traceable sources, its comprehensiveness and provenance tracking are unmatched.
The Best Approach: Use More Than One
Experienced practitioners almost universally discover that the most effective approach is to develop fluency in multiple repertories and use them in combination. Each repertory offers a different lens on the same symptom picture. A rubric that's sparse in Kent might be richly detailed in the Complete Repertory. A symptom that's hard to find in Kent's 19th-century language might be immediately obvious in Murphy's modern phrasing.
Why Using Multiple Repertories Gives the Best Results
Each repertory compiler brought a different clinical perspective to their work. Kent's deductive logic, Murphy's clinical pragmatism, and van Zandvoort's comprehensive documentation each illuminate different aspects of the symptom picture. By searching across multiple repertories for the same symptom, you reduce the risk of missing a clinically significant rubric or remedy.
Historically, working with multiple repertories meant maintaining several heavy volumes and manually cross-referencing between them. Modern software has eliminated this barrier entirely. Platforms like Similia make multi-repertory work seamless by providing a single search interface across 14+ repertories. Type a symptom once, and see matching rubrics from Kent, Murphy, Complete Repertory, Boenninghausen, Boger, and other sources in one unified view.
Similia offers Kent's Repertory free on all plans, with Murphy's MetaRepertory available through the Pro Murphy Edition and Complete Repertory 2026 through the Pro Complete Edition.
Frequently Asked Questions
Is Murphy's Repertory better than Kent's?
Neither is objectively better; they serve different purposes. Kent's is the foundational work every homeopath should study, and it remains the gold standard for classical prescribing methodology. Murphy's is more practical for daily clinical use, with modern language and broader sourcing. Many practitioners use both.
Can I use Complete Repertory as my only repertory?
In theory, yes — it contains the most extensive collection of rubrics available. However, its sheer size means that search results can be overwhelming without experience. Most practitioners find it most effective as a supplement to Kent or Murphy.
Which repertory is best for homeopathy students?
Kent's Repertory is the recommended starting point. It's universally taught, its structure reflects important principles of case analysis, and understanding Kent gives you the foundation to navigate any other repertory. For a comprehensive introduction, our beginner's guide to repertorisation covers the fundamentals.
Are there free versions of these repertories available?
Kent's Repertory is available free on many platforms, including Similia. Murphy's MetaRepertory and the Complete Repertory are premium resources that typically require a subscription.
How do Murphy and Complete Repertory differ from each other?
Murphy's is a clinically reorganised compilation designed for practical daily use, with modernised language. The Complete Repertory prioritises maximum coverage and source traceability. Murphy is faster in the consulting room; Complete Repertory is more thorough for in-depth research.
Do I need software to use these repertories?
Kent and Murphy are available in printed form. The Complete Repertory is primarily digital. Regardless of which repertory you prefer, modern software dramatically improves speed and effectiveness — particularly when working with multiple repertories simultaneously.
What is the difference between a repertory and a materia medica?
A repertory is organised by symptoms, listing which remedies are associated with each. A materia medica is organised by remedies, describing the full picture of each medicine. They are complementary tools: use the repertory to narrow candidates, then consult the materia medica to confirm your selection.
Can I switch between repertories in the same case analysis?
Absolutely, and many experienced practitioners do exactly this. You might begin in Kent, switch to Murphy for more clinically specific rubrics, and then consult the Complete Repertory for unusual symptoms. Software platforms that support multiple repertories make this workflow straightforward.
Conclusion
The repertory debate — Kent vs Murphy vs Complete Repertory — is ultimately a false choice. Each work represents a different philosophy, a different era, and a different set of strengths. Kent provides the philosophical foundation. Murphy delivers clinical practicality. The Complete Repertory offers unmatched comprehensiveness.
The most effective practitioners don't limit themselves to a single repertory. They develop familiarity with multiple sources and learn when each one is most useful. And they use a platform that makes searching across all of them as simple as typing a single query.
