How match sx with a remedy.
If we follow Hahnemann himself rather than later systems, the movement from a patient's physical symptoms to the selected remedy is quite systematic. And importantly, he does not say “find a physical symptom and match a remedy to it.” He moves from the whole observed disease picture → characteristic symptoms → comparison with the medicinal symptom picture → the most similar remedy.
I’ll use the 6th edition German as the controlling text, with English only as a secondary aid.
§3 — What the physician must know
The starting point is not a remedy.
Hahnemann says the physician must know:
„was an Krankheiten zu heilen ist“
and must know:
„die Arzneikräfte“
and:
„wie die Arzneien zur Heilung der Krankheiten anzuwenden sind“
So there are three distinct requirements:
What is to be cured in the individual patient.
What the medicines are capable of producing.
How to apply the medicines appropriately.
That already prevents the simplistic method:
“symptom → remedy.”
The physician must understand both sides of the comparison.
§5 — The circumstances of the case
Hahnemann does not merely collect isolated symptoms.
He says the physician should consider:
„die bedeutendsten Momente der Krankheitsgeschichte“
and asks about things such as the patient's constitution, occupation, mode of life, circumstances and possible causes.
This information helps construct the individual case.
But there is an important distinction: not everything discovered in the history is automatically a prescribing symptom.
§6 — Observe what has actually changed
This is one of the foundations.
Hahnemann begins:
„Der vorurtheilslose Beobachter …“
The physician observes the changes in the health of:
„Körper und Gemüth“
— body and mind.
And these are:
„die krankhaften Erscheinungen, Zufälle, Symptome“
In other words, the physician starts with the observable deviations from the patient's previous healthy state.
Hahnemann then says these perceptible signs collectively constitute:
„das wahre und einzig denkbare Bild der Krankheit“
the true and only conceivable picture of the disease.
This is crucial.
A physical symptom is part of the disease picture.
It isn't automatically the disease picture.
§7 — The symptoms point toward the remedy
This is where Hahnemann makes the connection.
He says:
„so müssen … es auch einzig die Symptome sein, durch welche die Krankheit die, zu ihrer Hülfe geeignete Arznei fordert und auf dieselbe hinweisen“
The symptoms are therefore what point toward the medicine required.
But he immediately makes the decisive qualification:
„die Gesammtheit dieser ihrer Symptome“
— the totality of its symptoms.
That totality is:
„das … nach außen reflectirende Bild des innern Wesens der Krankheit“
and is:
„das Einzige, was die Wahl des angemessensten Hilfsmittels bestimmen kann“
So Hahnemann's sequence is:
patient → observed changes → totality of symptoms → remedy selection.
Not:
one physical symptom → remedy.
§9 — The disease as alteration of the whole person
The diseased person is not regarded merely as a collection of disconnected organs.
The organism is altered as a whole.
Therefore the physician observes the patient's overall altered state, expressed through the symptoms.
§18 — The decisive statement
This is perhaps the clearest answer.
Hahnemann writes:
„der Inbegriff aller, in jedem einzelnen Krankheitsfalle wahrgenommenen Symptome und Umstände“
is:
„die einzige Indication, die einzige Hinweisung auf ein zu wählendes Heilmittel“
In plain terms:
The totality of the symptoms and circumstances observed in the individual case is the sole indication and guide to the medicine to be selected.
Notice the German:
Inbegriff aller … Symptome und Umstände
Not one symptom.
§§19–21 — Now compare this with medicines
This is the other side of the equation.
§19 says disease involves a change in the patient's condition:
„Befindensveränderungen“
while medicines possess the ability to alter human condition.
Then §21 asks: How do we know what a medicine can cure?
Hahnemann's answer is essentially: by observing what the medicine produces.
He says medicines produce:
„deutliche Veränderungen seines Befindens“
and particularly:
„mehrere, bestimmte Krankheitssymptome“
in healthy people.
Therefore:
„welche Krankheits-Erzeugungskraft jede einzelne Arznei … welche Krankheits-Heilungskraft jede besitze.“
This gives the second half of the method:
Patient's symptoms ↔ medicinal symptom.
§22 — The two sides must correspond
Now the physician has:
The natural disease
The patient's observed:
symptoms + circumstances
and:
The medicinal disease
The symptoms produced by a medicine in healthy provings.
The task is to find the medicinal disease that corresponds most closely to the natural disease.
This is where similia similibus becomes a practical method rather than merely a maxim.
§23–27 — Similarity becomes the therapeutic principle
Hahnemann distinguishes his method from merely opposing symptoms.
The central principle is:
a medicine capable of producing a similar artificial disease can remove the natural disease when the two symptom pictures correspond sufficiently closely.
The essential relationship is therefore:
natural disease picture
↓
comparison
↓
similar medicinal disease picture
↓
appropriate remedy
§30–34 — Similarity must be sufficiently strong
Hahnemann develops the idea that the medicinal disease must be sufficiently similar to the natural one.
The medicine is not selected because it is generally useful for the diagnosis.
It is selected because its effects on the healthy human being correspond to the individual patient's disease picture.
That is a very important distinction.
§153 — Now Hahnemann tells you what to give the greatest weight
This is the famous prescribing principle.
He begins:
„Bei dieser Aufsuchung eines homöopathisch specifischen Heilmittels“
and describes the comparison of:
„des Zeichen-Inbegriffs der natürlichen Krankheit“
with:
„den Symptomenreihen der vorhandenen Arzneien“
The physician is therefore comparing:
the total signs of the natural disease
with:
the symptom series of the medicines.
Then comes the critical instruction:
„die auffallendern, sonderlichen, ungewöhnlichen und eigenheitlichen (charakteristischen) Zeichen und Symptome“
must be:
„besonders und fast einzig fest ins Auge zu fassen“
That is:
particularly—and almost exclusively—kept in view.
Why does he say that?
Because general symptoms such as:
„Eßlust-Mangel, Kopfweh, Mattigkeit, unruhiger Schlaf“
may occur in many diseases and many medicines.
They therefore have relatively little discriminating value when they remain vague.
But a striking, peculiar, uncommon, characteristic symptom can separate one remedy from many others.
So §153 gives us the practical hierarchy:
Totality first → characteristic symptoms receive greatest weight.
§154 — This is the point at which the remedy is selected
Now Hahnemann describes the successful match.
The medicine's symptom picture contains the patient's:
„besondern, ungemeinen, eigenheitlich sich auszeichnenden (charakteristischen) Zeichen“
in the:
„größten Zahl“
and:
„größten Aehnlichkeit“
Then:
„so ist diese Arznei … das passendste, homöopathische, specifische Heilmittel“
That is probably the clearest answer
Hahnemann's actual test is not:
“Does the remedy have this physical symptom?”
It is:
“Does the remedy's symptom picture correspond to the patient's characteristic symptom picture in the greatest number and greatest similarity?”
§§210–213 — Physical symptoms are not enough
This is particularly important.
Hahnemann says that even in bodily diseases:
„die Gemüths- und Geistes-Verfassung allemal geändert ist“
and that the state of mind must be included in:
„den Inbegriff der Symptome“
§213 then says that one cannot cure:
„naturgemäß … homöopathisch“
unless one observes the mental/dispositional symptoms along with the other symptoms.
So Hahnemann's method does not reduce to physical prescribing.
The complete Hahnemannian chain
If we put the principal aphorisms together, the process looks like this:
§3
Know what is to be cured + know the medicines.
↓
§5
Establish the important circumstances and history.
↓
§6
Observe the actual deviations from health.
↓
§7
The symptoms constitute the outward disease picture and point toward the remedy.
↓
§9
Regard the altered state of the person as a whole.
↓
§18
The totality of symptoms and circumstances is the indication for the medicine.
↓
§19–21
Know medicines through what they produce in human beings.
↓
§22–27
Seek correspondence between natural and medicinal disease.
↓
§30–34
The medicinal disease must be sufficiently similar.
↓
§153
Give particular weight to the striking, singular, uncommon and characteristic symptoms.
↓
§154
Select the medicine whose symptoms correspond in the greatest number and greatest similarity.
If you take one physical symptom and find a remedy that produces that symptom, that is not yet Hahnemann's method.
If you take the patient's complete observable disease picture, identify its characteristic features, know the medicinal symptom pictures from provings, and find the medicine whose symptom picture corresponds with the patient's picture in the greatest number and greatest similarity, that is the prescribing process Hahnemann describes.
And there is an important subtlety in the German: §153 says „fast einzig“—“almost exclusively”—about the characteristic symptoms, but §154 still requires the characteristic signs to occur in the greatest number and greatest similarity. So Hahnemann is not saying ignore everything except one peculiar symptom. He is describing a totality-based comparison in which characteristic symptoms have the greatest discriminating weight.
