In Jan Scholten's periodic table, which reflects the various developmental stages of human life, the Iron series represents the start of adult life with its associated tasks and duties. Topics, such as discipline, routine, rules, control, perfection, and the feeling of guilt associated with failure are characteristics of this phase, in which the superego and society both take their toll. The resulting conflicts highlight each element of the Iron series in its own way.
SPECTRUM presents the developmental stages of the fourth series of the periodic table with a number of case histories and a variety of illnesses. Together with familiar remedies, such as Kalium, Ferrum, Zincum, or Arsenicum, accompanied by their salts, we will look at less familiar remedies, such as Scandium, Titanium, Vanadium, Gallium, and Germanium. The themes of the Iron series and their manifestation in the various stages help us to achieve a better understanding of both familiar and new remedies. The aim of this chapter of our modern materia medica is therefore to comprehensively demonstrate the practical application of the elements of the periodic table, exemplified by the Iron series.
