Preface :
The concordance repertory is designed to enable the physician to find quickly and certainly any desired symptom in the materia medica together with the indicated remedy .

The rules adopted for the preparation of the work — are
1) Select and give all the more characteristic pathogenetic symptoms.
2) Include only such clinical symptoms as have been repeatedly verified.
3) When two or more remedies have the power of producing a similar condition, include them as merely suggestive, under the name of the condition produced.
4) Give the noun, verb, and essential adjective in the sentence.
The idea which finally gave origin to the work presented itself in the autumn of 1876.

Author wanted to find a remedy for a symptom — the symptom which caused the search is ” constant dull frontal headache , worse in the temples, with aching in the umbilicus ” — that peculiarity made it difficult to find .
After a weary search and final success in finding the remedy, the
Author exclaimed — if only we had a repertory arranged on the plan of Cruden’s Concordance of the Bible, it would have been necessary only to refer to the letter ‘ U ‘ and under ‘ umbilicus ‘ find at once the desired symptom.
It was decided then that the attempt should be made to materialize the thought into activity , and with a determined will the work was begun.

The work comprised of six large volumes.
In searching for any desired symptom, the physician should first express it mentally , or better in writing, employing words commonly used, and then select the word in the sentence expressing the central thought, idea, fact, condition or object of the sentence or the noun, verb, essential adjective, and referring in the concordance to the word selected . [ the synonyms should also be thought of ]

For eg :
Imagination of having two heads — is a mental symptom, should be found in the section devoted to the Mind and Disposition.’ imagination’
being a noun, the first word and word expressing the central thought, we select that, and turning to the letter ‘ I’ in the proper section, find the word in the bold face letters and follow it with the desired symptom, together with all other symptoms in the materia medica in which the word “ imagination ” appears., grouped together , convenient for consideration and comparison.

Another eg :
“ Fancies seeing cats and dogs ” – this may be found in C following “ cats ” , in D following “ Dogs ” and in F following “ Fancies ” .
And in the like manner any symptom in the concordance may be found .
Frequent difficulty may be met in finding a symptom on account of difference in phraseology of the materia medica writers or upon the part of the person desiring to find the symptom. Therefore, when there is a failure to find a symptom under one word, the synonym should be thought of.

For eg :
Wants to do something and yet feels no ambition —
While the symptom can be found referring to ” do “, “ something ” and “ambition” .
Yet the word ‘ wants ‘ cannot be found , because the writer of the symptom
did not use that word .the word used in the materia medica is ” Desires” and
symptom can be found by referring to that word in the concordance.

For eg :
” Desires to kiss everybody ” — we get that symptom as —
” wants to kiss everybody ” . Think of the synonym ” wants ” or some other word  in the sentence, such as ” kiss ” or everybody ” .
