A homeopathic repertory is the symptom index of homeopathy: a large, cross-referenced book or database that lists symptoms as rubrics and, under each rubric, the remedies homeopaths have traditionally associated with that symptom. If the materia medica answers the question “what does this remedy do?”, the repertory answers the opposite question: “the patient has this symptom — which remedies have historically matched it?” James Tyler Kent’s Repertory of the Homeopathic Materia Medica is the ancestor of nearly all modern editions, and the structure he established — chapters by body region, rubrics from general to specific, and remedies printed in graded typefaces — is still what you see today. You do not need to be a practitioner to read one; you need to understand its logic.
This guide explains that logic in plain language, so you can follow a professional’s reasoning, look things up sensibly for a mild self-limiting complaint, and avoid the traps that make beginners misread the book.
A Repertory Is an Index, Not an Answer Book
The single most useful idea to hold onto is that a repertory is an index. It points; it does not diagnose, prescribe, or explain. In homeopathic practice the repertory is used in a loop with two other tools:
- Case-taking — the structured interview that collects the complaint, its modalities, concomitants, and the person’s general and mental state.
- The repertory — used to convert those recorded symptoms into candidate remedies.
- The materia medica — used to confirm that a candidate remedy genuinely fits the whole case, not just one line of it.
A remedy that tops a computer repertorization but does not match the person in the materia medica is a false lead. Skipping the confirmation step is the classic beginner error.

Kent’s layout divides the body and mind into fixed chapters, always in the same order. In a standard edition you will find, roughly: Mind, Vertigo, Head, Eye, Vision, Ear, Hearing, Nose, Face, Mouth, Teeth, Throat, External Throat, Stomach, Abdomen, Rectum, Stool, Bladder, Kidneys, Prostate Gland, Urethra, Urine, Male Genitalia, Female Genitalia, Larynx and Trachea, Respiration, Cough, Expectoration, Chest, Back, Extremities, Sleep, Dreams, Chill, Fever, Perspiration, Skin, and Generalities. Inside each chapter, rubrics run from broad to narrow in an indented hierarchy — a main rubric such as “Cough” with sub-rubrics beneath it for time, type, and circumstance.
Two habits make navigation far easier:
- Start broad, then narrow. Find the chapter, then the main rubric, then the sub-rubric that carries the patient’s most characteristic detail.
- Read the Generalities chapter deliberately. It holds whole-person symptoms — time of aggravation, weather, food cravings, constitution — that often decide the case.
Reading a Rubric: Gradations, Sides, and Modalities
Under each rubric, remedies are printed in a hierarchy that homeopaths call gradation. In Kent-style repertories the convention is: bold for the strongest and most frequently confirmed association, italics for a moderate one, and plain roman type for a weaker or less often confirmed one. Modern “expanded” repertories replace typefaces with a numeric grade, usually 1 to 4, which is what repertorization software uses when it adds up points.
Rubrics also carry structural details that matter more than the remedy list itself:
- Laterality — “left” or “right” variants of the same complaint sometimes sit in separate sub-rubrics, because sides are a genuinely characteristic feature in homeopathic case-taking.
- Timing — “morning”, “midnight”, “2 a.m.”, “periodic”. Time patterns are treated as high-value individualizing detail, not trivia.
- Modalities — “cough, warmth, from” or “pain, pressure, amel.” (amel. means better for, agg. means worse for). These “better/worse” entries are often the sharpest filters in the whole book.
- Sensations — burning, stitching, tearing, bursting, “as if” descriptions. Homeopaths treat an “as if” sensation as a legitimate symptom when the patient volunteers it.
Kent’s, Boericke’s, and Expanded Repertories Compared
Three families of repertory are in common use, and they serve different purposes:
- Kent’s Repertory — single-author, compact, philosophically consistent. Fewer rubrics, but the ones present are well tested in classical practice. Good for learning structure.
- Boericke’s — smaller and more practical, often bound together with a short materia medica. Useful at the bedside for acute, everyday prescribing.
- Expanded/modern repertories — multi-author, enormously larger, with hundreds of thousands of cross-references and confirmed additions. Excellent coverage, but the sheer volume means a carelessly chosen rubric can pull in remedies that are only loosely related.
None of these is “more accurate” in an absolute sense. In homeopathic practice the choice is a trade-off between a lean, reliable map and a wide, detailed one.
Where Computer Repertorization Fits In
Digital repertories do the arithmetic that makes paper work slow: they take the rubrics you selected, apply the grade of each remedy within each rubric, and return a ranked list with a running total. This is called repertorization. It is a genuine convenience and it is also where people get misled, for three reasons:
- Point totals reward generality. Broad rubrics are shared by dozens of remedies; a handful of small, precise rubrics usually discriminates better.
- Diagnoses are not rubrics. Entering a medical diagnosis produces a vague answer; entering the patient’s actual sensations, modalities and concomitants produces a useful one.
- The ranking is a shortlist, not a verdict. The final choice still requires reading the candidate remedies in the materia medica and, ideally, discussing the case with a qualified practitioner.
Five Mistakes Beginners Make
- Using the patient’s wording as a rubric. Translating “my head feels like it’s in a vice” into a standard rubric takes practice.
- Piling on rubrics. Ten rubrics dilute each other; three or four truly characteristic ones carry the case.
- Ignoring modalities. “Worse for cold, better for warmth” can matter more than the location of the pain.
- Confusing repertory and materia medica. The first suggests, the second confirms.
- Self-prescribing for chronic or serious conditions. A repertory is not a substitute for professional care, especially where the symptoms are worsening.
A Worked Reading Walk-Through
Suppose your notes read: “dry cough, worse at midnight and from cold air, better for sips of warm water, with restlessness and a fear of the dark.” A repertory reading follows a fixed path:
- Choose the chapter. The complaint is respiratory, so start in Cough, and note that the general time pattern also belongs in Generalities.
- Take the most characteristic line first. “Worse at midnight” is more individualizing than “dry”, which half the cough rubrics share.
- Add the modality. “Better for warm drinks” and “worse from cold air” are two distinct rubrics and both discriminate.
- Add one general or mental feature. Restlessness and fear of the dark belong to Mind, and in homeopathic practice they often carry more weight than the physical details.
- Intersect the lists. Look for remedies that appear under several of your rubrics, not most rubrics.
- Confirm in the materia medica. Read the shortlist remedies in full before choosing.
The output of that process is a shortlist of three to five candidate remedies, not a prescription. The discipline is in step five: a remedy present in four well-chosen rubrics is usually a better lead than a remedy present in ten vaguely chosen ones.
Repertory Vocabulary You Will Meet
Homeopathic reference works use a small, consistent shorthand. Knowing it prevents most misreadings:
- Rubric — one symptom entry, with its remedies listed beneath it.
- Grading — the strength of the historical association between remedy and rubric, shown by typeface or a number.
- Agg. / amel. — aggravated by, or ameliorated (improved) by. These indicate modalities.
- Concomitant — something that appears alongside the main complaint and is treated as a symptom in its own right.
- Keynote — a striking, unusual symptom strongly associated with a particular remedy.
- Totality — the complete, individual symptom picture that a prescription is meant to match.
Two practical notes. First, rubrics are worded in an older, formal register: “as if”, “pain, stitching”, “amel. by pressure”. Second, the Generalities chapter is deliberately last but should be read early, because whole-person symptoms such as time of aggravation, weather sensitivity and food preferences frequently decide a case. A reader who only searches the organ chapters will collect the least discriminating half of the case.
Frequently Asked Questions
Do I need a repertory to use homeopathy at home?
No. For simple, self-limiting complaints a short first-aid guide or a starter-kit leaflet is enough. A repertory becomes useful when you want to understand how a professional reasons about a more detailed symptom picture.
What do the bold, italic and plain entries actually mean?
They are homeopathy’s traditional grading of how strongly and how often a remedy has been associated with that rubric — bold strongest, italic moderate, plain weakest. Expanded repertories render the same idea as numbers.
Can a repertory tell me my constitution?
Not by itself. The concept of the constitutional remedy is built from the whole case — mental and general symptoms, modalities, history — and the repertory is only one input into that judgement.
Is repertorization the same as diagnosis?
No. Homeopathy works from the individual’s symptom picture rather than from a disease name, and it is used as a complementary approach. A diagnosis still belongs with a medical professional.
Where should a complete beginner start?
Learn case-taking first: location, sensation, modalities, concomitants. A person who can collect those accurately can use any repertory well; a person who cannot will misread even the best one.
