Homoeopathy is a scientific method of symptom similarity in its application
What homoeopathy has shown to be true a century ago is true today, for symptoms of disease and symptoms of drug don’t change and that is the rock on which the basis of homoeopathy rests.
Hahnemann is considered as the father of homoeopathy but he was not the first clinician to note that drugs selected on the basis of their similarity to the disease cure. He cites previous experiences of clinicians like Hippocrates, Paracelsus and stahl (1738) in whose wittings; he finds the most definite statement of the law of similar. But none of these proceeded systematically to offer an experimental proof.
