Mental & Emotional Diseases

Organon Aphorism §210

Of psoric origin are almost all those diseases that I have above termed one-sided, which appear to be more difficult to cure in consequence of this one-sidedness, all their other morbid symptoms disappearing, as it were, before the single, great, prominent symptom. Of this character are what are termed mental diseases. They do not, however, constitute a class of disease the condition of the disposition and mind is always altered; and in all cases of disease we are called on to cure the state of the patient’s disposition is to be particularly noted, along with the totality of the symptoms, if we would trace an accurate picture of the disease, in order to be able therefrom to treat it homoeopathically with success.

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