According to Hahnemann:- Common / General Uncommon / Peculiar
According to Boenninghausen: - Primary / Typical, Secondary / Concomitant
In the lesser writing Dr. Boenninghausen had said- “First of all, those symptoms which are found in almost all disease may be left out at our count unless they manifest themselves in a striking manner.
On the other hand, those entire attendant symptoms should be carefully noted which:
(ii) Those which belong to another sphere of disease than the chief ailment.
(iii) Lastly those which have more or less of the characteristic signs of one of the medicines.
Such a symptoms would be included among those which Hahnemann calls “More striking, singular, uncommon and peculiar (Characteristic), signs”, because they predominantly give to the whole disease in its individual Character. (2)
