It is exceptional to find a patient as sensitive as this remedy not homeopathically related to the case.

But in disease, the patient becomes excessively sensitive to the remedy which has caused corresponding symptoms, that is to say, to the remedy which is homeopathic to his condition.

Experience taught Hahnemann that a very much smaller amount of the corresponding drug was needed to cure then that required to produce the symptoms.

Experience has confirmed the fact in the practise of thousands of his followers ; and it now remains established beyond the possibility of disproof.
