XVII. Knowledge of Substance as a Basis for the Knowledge of Medicaments

Therefore, in these conditions of illness, only mineral substances will be useful as remedies. In order to get to know the remedial effects of a mineral, we must discover how far the substance can be broken down, for in the organism the mineral introduced from outside must first be broken down and then built up again in a new form by the body's organic forces. The healing influence must consist in this breaking down and building up process. The outcome of it must lie in the direction that a deficient activity of the organism is taken over by the activity of the medicament given.
