One-Sided Diseases

Organon Aphorism §180

In this case the medicine, which has been chosen as well as was possible, but which, for the reason above stated, is only imperfectly homoeopathic, will, in its action upon the disease that is only partially analogous to it – just as in the case mentioned above (§ 162, et seq.) where the limited number of homoeopathic remedies renders the selection imperfect – produce accessory symptoms, and several phenomena from its own array of symptoms are mixed up with the patient’s state of health, which are, however, at the same time, symptoms of the disease itself, although they may have been hitherto never or very rarely perceived; some symptoms which the patient had never previously experienced appear, or others he had only felt indistinctly become more pronounced.

Study notes for this aphorism are not published yet. They appear here once a homeopath has reviewed them.
