Jan Scholten has created a Materia Medica of the periodic table - (most elements are either almost unknown or completely missing from standard texts). By using his "Group Analysis Method" - ( looking at individual remedies according to the themes they present and their relationship to others at different points on the periodic table) - he allows combinations and connections across different themes.His system, detailed with many case illustrations, enables us to make these connections ourselves. His painstaking method, research, and inquiring mind have greatly enriched the prescribing potential of homoeopathy.
