Organon §158

A small homeopathic aggravation is a good indication in an acute disease.

This small homeopathic aggravation in the first hours is a very good portent that the acute disease will be mostly finished by the first dose. Such an aggravation is not infrequent, since the medicinal disease must naturally be somewhat stronger than the malady in order to over-tune and extinguish it, just as a natural disease can only lift and annihilate another similar natural disease if it is stronger than the other one (§43-§48).
