Glossary

Every difficult term of the classical literature, in plain words.

Foundations

Potency
The strength of a homeopathic preparation, expressed as a number with a scale letter — 6C, 30C, 200C. Each C-step dilutes one part in a hundred and shakes vigorously. Higher numbers mean greater dilution, not greater strength of original substance.
Trituration
The grinding of the original substance with milk-sugar to make it soluble enough to begin the dilution process; the first step for insoluble materials.
Mother tincture
The starting alcohol extract of a plant or other material, labelled with the Latin name and pharmacy symbol (Ø), from which dilutions are prepared.
Proving
The structured testing of a substance on healthy volunteers, recording every symptom produced, to build the remedy's portrait.
Simillimum
The 'most similar' remedy — the one whose proving picture best matches the patient's whole pattern.
Vital force
The old term for the body's self-healing capacity — what modern physiology would call regulation, repair and immunity working together.

Prescribing terms

Keynote
A striking, characteristic symptom that strongly suggests a remedy — like 'burning better from heat' for Arsenicum.
Totality of symptoms
The whole pattern — mind, body, modalities, peculiarities — rather than any single complaint.
Constitution
The person's lifelong pattern of reactivity and build; constitutional remedies treat the person, not the moment.
Modalities
The factors that worsen (aggravations) or relieve (ameliorations) symptoms — heat, cold, motion, time of day, company.
Aggravation
A temporary worsening of symptoms after the remedy, once interpreted as a sign of action.
Concomitant
A symptom accompanying the chief complaint that completes the picture.
Alternation
Symptoms that swap sides or change places — 'now the head, now the bowels'.
Never-well-since
A complaint dating from a specific event — a grief, a drug, a fever — that shaped everything after.

Materia medica terms

Affinity
The organs or systems a remedy was traditionally thought to act on most.
Diathesis
An inherited tendency toward certain complaints — the 'rheumatic diathesis', the 'gouty diathesis'.
Nosode
A remedy prepared from disease material itself — Psorinum from scabies, Tuberculinum from tuberculosis — recording the disease's portrait.
Sarcode
A remedy prepared from healthy tissue secretions, by contrast with nosodes.
Antipsoric
A remedy of the chronic, inherited tendency — Sulphur stands at the head of the class.
Repertory
The index of symptoms cross-referenced to remedies — the symptom-to-remedy dictionary of the library.
Rubrics
The symptom categories of the repertory — 'MIND, anxiety, midnight'.
High potency / low potency
The dilution convention: below 12C is 'low' (some original molecules remain), above is 'high'.

Old clinical language (as the books use it)

Cachexia
The wasted, depleted state of long chronic illness — thin, sallow, exhausted.
Chlorosis
The 'green sickness' of young women — iron-deficiency anaemia with its flushed-but-tired face.
Scrofula
Chronically enlarged, unhealthy glands of childhood — the pre-antibiotic tonsil-and-gland picture.
Marasmus
The melting, wasting state of infants who fail to thrive.
Quinsy
Peritonsillar abscess — the one-sided throat swelling of the old books.
Dropsy
Generalised fluid retention — the era's name for heart and kidney failure's swelling.
Typhoid state
The low, dull, drowsy fever with its dark face and muttering delirium.
Hydrophobia
Rabies — the water-spasm of the old books.
Hectic fever
The wasting fever of chronic infection, with its flush and sweat.
Vicarious
A discharge or symptom appearing in place of another — 'the skin acting for the lungs'.
Metastasis
A complaint that migrates from one system to another — rheuma that 'flies to the heart'.
Idiosyncrasy
An unusual personal sensitivity to a substance — the era's term for allergy.
