He said that when an organism or a human being gets into stress, the usual physiologic systems are interrupted and the resulting changes cause diseases. The physical and emotional upset organisms experienced upon injection of the toxic substance caused such patterns to develop which would cause infection, disease and ultimately death if left untreated.
