And then Hahnemann’s Initial Aggravation – transient and little noticed in acute sickness, but often very definite in chronic disease; where it may occur during the first eight to ten days. It was the initial aggravation that caused hahnemann, as we said to reduce his doses : and which led presently to the establishment of the fact, that when remedies are reduced again and again by repeated subdivision into the region of infinitesimals, there is no loss, but an augmentation of energy.
And therefore, as time went on, and observation was added to observation,”dilutions ” became for him “potencies”, and the 30th dilution (“one in a decillion”) was more correctly named, the 30th power, or potency.
Initial aggravation is succeeded by a period of amelioration Sir Almroth Wright has called it a “Positive phase.” which, Hahnemann says must not be interfered with. Vital reaction has been brought into play, and must be permitted to work itself out.
