Isopathy has conceived about 200 years ago, Which states that “All the contagions carry in their substance even the means of their cure.” Although good, it was a vague idea as the germ theory and disease causation were not known.
Ignorant of this fact, the nosode was prepared from different natural materials/fluids without any scientific knowledge of the disease, germ, and its infectivity. Hence the results were not uniform and successful. It has since been consigned to oblivion.
The idea that it could be improved and used in Viral diseases/epidemics and Exogenous toxic states was not conceived previously.
