Homeopathic consultations come with their own vocabulary, and understanding it makes the process far less mysterious. This glossary defines fifty terms you are likely to hear, in the order you are likely to meet them, so that a case-taking session, a potency recommendation or a repertory entry stops feeling like a foreign language. None of these definitions are treatment advice. Homeopathy is complementary care, used alongside — never instead of — medical assessment.
The Core Principles
Homeopathy — a system of complementary medicine founded by Samuel Hahnemann in the late eighteenth century, which selects remedies by symptom resemblance rather than by diagnosis.
Law of similars — the founding principle that a substance which can produce symptoms in a healthy person may, when prepared homeopathically, be used to treat a similar symptom picture in a sick person.
Similia similibus curentur — Latin for “let like be cured by like”, the formal statement of the law of similars.

Vital force — the traditional term for the body’s self-regulating capacity, which homeopaths hold remedies are intended to support.
Holistic — treating the person as a whole, taking mental, emotional and physical symptoms together rather than in isolation.
How Remedies Are Made
Dilution — the stepwise process of reducing a substance’s concentration, typically in a ratio of one part to nine (X or D scale) or one part to ninety-nine (C scale).
Succussion — the vigorous shaking performed at each dilution step; in homeopathic preparation, dilution and succussion together are called potentization.
Potentization — the combined process of diluting and succussing a substance to produce a remedy.
Potency — the number and scale that describe how far a remedy has been potentized, such as 6X, 30C, 200C or 1M.
X scale (decimal) — a dilution series where each step is one part in ten; 6X means six such steps.
C scale (centesimal) — a dilution series where each step is one part in one hundred; 30C means thirty such steps.
M scale — a thousand-fold centesimal scale; 1M means 1,000C.
LM or Q potency — a very low-dose series developed by Hahnemann, in which each step is diluted 1:50,000.
Mother tincture — the concentrated botanical extract from which diluted potencies are made, usually denoted by the symbol theta.
Nosode — a remedy prepared from a pathological product or an organism-derived material, used in some homeopathic traditions.
Imponderabilia — remedies prepared from non-material sources such as light, magnetism or x-ray energy, used in some schools.
Remedy Sources and Categories
Materia medica — the reference collection describing each remedy’s symptom picture.
Proving — a structured trial in which healthy volunteers record the symptoms produced by a substance, forming the basis of its homeopathic picture.
Polycrest — a remedy with a very broad and well-studied symptom picture, used in many different cases.
Constitutional remedy — the remedy considered to fit a person’s whole long-term constitution rather than one acute complaint.
Acute remedy — a remedy chosen for a short, self-limiting episode rather than a chronic pattern.
Organ remedy — a remedy selected for a specific organ or tissue rather than the whole constitution, in some homeopathic traditions.
Combination remedy — a product containing several low-potency remedies together, as distinct from classical single-remedy prescribing.
The Consultation and the Case
Case-taking — the structured interview in which the practitioner records the full symptom picture, including onset, location, sensation, modalities and emotional state.
Repertory — an index of symptoms that lists the remedies associated with each, used to build and compare the case.
Rubric — a single entry in a repertory, such as “headache, worse in the morning”.
Modality — anything that makes a symptom better or worse, for example warmth, motion, fresh air or pressure.
Concomitant — a symptom that appears alongside the main complaint and helps narrow the remedy choice.
Strange, rare and peculiar — homeopathic shorthand for unusual symptoms that are considered especially valuable for prescribing.
Totality of symptoms — the complete picture assembled from all symptoms, not just the chief complaint.
Repertorization — the process of translating a case into rubrics and comparing the remedies they have in common.
Differential — the shortlist of remedies that plausibly fit before the final choice is made.
Timing, Reactions and Progress
Aggravation — a temporary intensification of symptoms after a dose, traditionally interpreted as a reaction to the remedy.
Amelioration — improvement of symptoms; the opposite of aggravation.
Herring’s law of cure — the homeopathic observation that healing is said to move from within outward, from above downward, and from more vital to less vital organs.
Proving symptom return — the reappearance of old symptoms during treatment, traditionally read as a sign that an older layer is being re-addressed.
Antidote — something that appears to cancel a remedy’s action, such as strong odours, coffee or dental work in some homeopathic accounts.
Interval — the waiting period between doses, chosen according to the remedy, the potency and the person’s response.
Repetition — how often a dose is repeated; less repetition is usual with higher potencies.
Placebo — an inactive treatment effect; a concept frequently raised in critiques of homeopathy, and one homeopaths discuss in terms of individual response rather than by dismissing it.
Laws of cure review — the periodic reassessment of whether the case is moving in the expected direction.
Historical and Theoretical Terms
Hahnemannian — referring to the original method of Samuel Hahnemann, emphasizing single remedies and provings.
Kentian — referring to the approach of James Tyler Kent, emphasizing the mental and constitutional picture and high potencies.
Miasm — a traditional concept describing a chronic background tendency inherited or acquired over a lifetime, such as psora, sycosis or syphilis in classical terminology.
Psora — in classical homeopathy, the oldest and broadest miasmatic category, associated with suppressed skin conditions in traditional accounts.
Sycosis — traditionally associated with overgrowth and excess patterns in miasmatic theory.
Nosode in miasmatic work — the use of organism-derived remedies in some miasmatic prescribing systems.
Suppression — the traditional homeopathic idea that suppressing a surface symptom with local treatment may push the disturbance deeper; a contested belief, held within the homeopathic tradition rather than established fact.
Second prescription — the practitioner’s choice of what to do after an initial response, often the most delicate decision in a long case.
Antipsoric — a traditional classification of remedies and treatment for chronic, deep-seated cases.
Organic vs functional — the distinction between changes in tissue structure and changes in function alone, which influences how homeopaths frame a case.
Homeopathy Compared with Neighbouring Terms
Allopathy — a term used in homeopathic writing for conventional medicine, which treats disease by opposing its mechanisms; in ordinary use, the medicine practised by licensed physicians.
Herbal medicine — the therapeutic use of concentrated plant material, delivering measurable amounts of active constituents, which distinguishes it clearly from homeopathic dilution.
Isopathy — the use of a substance based on the disease it is associated with rather than on symptom similarity.
Naturopathy — a broader system emphasizing diet, lifestyle and natural agents, which may include homeopathy without being defined by it.
How to Actually Use This Glossary
The point of a glossary is not memorization but recognition. In a consultation, the terms that will actually change what you do are a small set: case-taking, potency, modality, interval and aggravation. If you understand those five, you can follow a treatment plan, describe your symptoms usefully, and know what a practitioner means when they say a dose should not be repeated yet.
The rest of the vocabulary becomes useful over time, particularly the terms connected to the remedy itself. Knowing that 30C and 30X describe different scales, and that a mother tincture is a concentrated extract rather than a diluted potency, prevents the most common confusion in home self-care.
Where the Vocabulary Comes From
Many of these words are historical rather than clinical. Miasm, psora and suppression come from nineteenth-century homeopathic theory and are best read as a working model inside the tradition rather than as established biology. Others, such as dilution, succussion and potentization, describe a manufacturing process and are entirely concrete. Distinguishing the two kinds of term makes homeopathic writing much easier to read.
None of this replaces medical assessment. Whatever the vocabulary suggests, symptoms that are severe, worsening or unfamiliar belong with a qualified clinician.
Frequently Asked Questions
Do I need to know all of this before my first appointment?
No. A good practitioner explains terms as they arise. This glossary is for orientation, and case-taking works best when you simply describe your experience in ordinary words.
Is the 30C on a label the same as 30X?
No. The letter gives the scale and the number the steps. 30C means thirty centesimal steps, while 30X means thirty decimal steps, and the two are very different in potency.
What does “constitutional” really mean in practice?
It describes the remedy chosen for the whole long-term pattern, reviewed over months, as opposed to a remedy used for a short acute illness.
Why do homeopaths use words like “miasm” that other medicines do not?
They come from the historical theory of homeopathy. They are part of the homeopathic framework, and homeopaths hold them as a working model rather than as established biological fact.
