Organon §153

Strange, rare and peculiar symptoms are the most important in the search for a homeopathic remedy. 

In the search for a homeopathically specific remedy, that is, in the comparison of the complex of the natural disease's signs with the symptom sets of the available medicines (in order to find among them an artificial disease potence that corresponds in similarity to the malady to be cured) the more striking, exceptional, unusual, and odd (characteristic) signs and symptoms 170 of the disease case are to be especially and almost solely kept in view. These, above all, must correspond to very similar ones in the symptom set of the medicine sought if it is to be the most fitting one for cure. The more common and indeterminate symptoms (lack of appetite, headache, lassitude, restless sleep, discomfort, etc.) are to be seen with almost every disease and medicine and thus deserve little attention unless they are more closely characterized. 

Comment

170 In arranging the characteristic symptoms of homeopathic medicines in his Repertory, Baron von Boenninghausen has earned our esteem, as has Dr. G.H. G. Jahr with his Handbook of Chief Indications, now in its third printing under the title Grand Manuel.
