Dr. Cartoon.
I can't believe that you are only cartoon by putting this wonderful question.
I am convinced with the remarks given by drmas and ricky.

Obviously if a well selected remedy is not working then surly it was wrongly selected.
In our body there are several layers of hurdles in the way of cure and we have to remove those layers with the help of atomic war heads. After long experiences of great homeopaths, they compiled data of those remedies which can produced some reaction in the body, irrespective of symptoms and disease which the patient has. These remedies are our last weapon on patient.
