One-Sided Diseases

Organon Aphorism §183

Whenever, therefore, the dose of the first medicine ceases to have a beneficial effect (if the newly developed symptoms do not, by reason of their gravity, demand more speedy aid – which, however, from the minuteness of the dose of homoeopathic medicine, and in very chronic diseases, is excessively rare), a new examination of the disease must be instituted, the status morbi as it now is must be noted down, and a second homoeopathic remedy selected in accordance with it, which shall exactly suit the present state, and one which shall be all the more appropriate can then be found, as the group of symptoms has become larger and more complete.
