Organon §220

Seek an antimiasmatic remedy capable of arousing similar symptoms to those of the disease, especially its mental symptoms.

4. By adding the patient’s mental and emotional state 190 (accurately observed by the patient’s relations and by the physician himself) to the patient’s somatic symptoms, a complete image of the disease is put together. In order to homeopathically cure the malady (if the mental disease has already lasted for some time) a medicine must be sought from among the (antipsoric, etc.) medications which is capable of arousing aptly similar symptoms and, especially, the similar mental derangement.
